Segment Reporting [Abstract]

Segment Reporting

25.	SEGMENT REPORTING

The Company’s operations are organized into two segments, consisting of Baidu Core and iQIYI. Baidu Core mainly provides search-based, feed-based and other online marketing services, cloud services, products and other services from its new AI initiatives. iQIYI is an online entertainment service provider that offers original, professionally produced and partner-generated content on its platform.

The Company derives the results of the segments directly from its internal management reporting system. The CODM reviews the performance of each segment based on its operating results and uses these results to evaluate the performance of, and to allocate resources to, each of the segments. Because substantially all of the Group’s long-lived assets and revenues are located in and derived from the PRC, geographical segments are not presented. The Company does not allocate assets to its segments as the CODM does not evaluate the performance of segments using asset information.

The table below provides a summary of the Group’s operating segment operating results for the year ended December 31, 2021.

Due to adverse changes in the expected performance of certain produced content and the reduced amount of ultimate revenue expected to be recognized, iQIYI performed an assessment to determine whether the fair value was less than unamortized content costs. iQIYI uses a discounted cash flow approach to estimate the fair value of the produced content titles predominantly monetized on its own. The significant unobservable inputs (level 3) include forecasted future revenues, production costs required to complete the content and exploitation and participation costs. iQIYI considers the historical performance of similar content, the forecasted performance and/or preliminary actual performance subsequent to the release of the produced content in estimating the fair value. Based on the above assessment, certain produced content predominantly monetized on its own were determined to be impaired and re-measured to the fair value as of each quarter end. Impairment charges of RMB161 million, RMB68 million and RMB253 million (US$36 million) were recognized for produced content predominantly monetized on its own and was recognized as cost of revenues in the consolidated statements of comprehensive income for the years ended December 31, 2021, 2022 and 2023, respectively.

Due to declined financial performances and changes in business circumstances of certain investees, the Group recognized impairment charges of long-term investments in the consolidated statements of comprehensive income during the years ended December 31, 2022 and 2023. For equity securities accounted for under the measurement alternative, when there are observable price changes in orderly transactions for identical or similar investments of the same issuer, the investments are re-measured to fair value.

Convertible Senior Notes

15.	CONVERTIBLE SENIOR NOTES

iQIYI 2023 Convertible Senior Notes

On December 4, 2018, iQIYI issued US$750

million convertible senior notes (the “iQIYI 2023 Convertible Notes”). The iQIYI 2023 Convertible Notes are senior, unsecured obligations of iQIYI, and

interest is payable semi-annually in cash at a rate of 3.75% per annum on June 1 and December 1 of each year, beginning on June 1, 2019. The iQIYI 2023 Convertible Notes will mature on December 1, 2023 unless redeemed, repurchased or converted prior to such date.

The initial conversion rate of the iQIYI 2023 Convertible Notes is 37.1830 of iQIYI’s ADS per US$1,000 principal amount of the iQIYI 2023 Convertible Notes (which is equivalent to an initial conversion price of approximately US$26.89 per ADS). Prior to June 1, 2023, the iQIYI 2023 Convertible Notes will be convertible at the option of the holders only upon the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2019, if the last reported sale price of ADSs for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price; (2) during the five business day period after any ten consecutive trading day period in which the trading price per US$1,000 principal amount of notes was less than 98% of the product of the last reported sale price of the ADSs and the conversion rate on each such trading day; (3) if iQIYI calls the notes for a tax redemption; or (4) upon the occurrence of specified corporate events. Thereafter, the iQIYI 2023 Convertible Notes will be convertible at the option of the holders at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. The conversion rate is subject to adjustment in some events but is not adjusted for any accrued and unpaid interest. In addition, following a make-whole fundamental change that occurs prior to the maturity date or following iQIYI’s delivery of a notice of a tax redemption, iQIYI will increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event or such tax redemption. Upon conversion, iQIYI will pay or deliver to such converting holders, as the case may be, cash, ADSs, or a combination of cash and ADSs, at its election.

The holders may require iQIYI to repurchase all or portion of the iQIYI 2023 Convertible Notes for cash on December 1, 2021, or upon a fundamental change, at a repurchase price equal to 100% of the principal amount, plus accrued and unpaid interest.

In connection with the issuance of the iQIYI 2023 Convertible Notes, iQIYI purchased capped call options (the “2023 Capped Call”) on iQIYI’s ADS with certain counterparties at a price of US$68 million. The counterparties

agreed to sell to iQIYI up to approximately 28 million of iQIYI’s ADSs upon iQIYI’s exercise of the 2023 Capped Call. The exercise price is equal to the iQIYI 2023 Convertible Notes’ initial conversion price and the cap price is US$38.42 per ADS, subject to certain adjustments under the terms of the capped call transactions. The capped call transactions are expected to reduce potential dilution to existing holders of the ordinary shares and ADSs of iQIYI upon conversion of the iQIYI 2023 Convertible Notes and/or offset any potential cash payments that iQIYI is required to make in excess of the principal amount of any converted notes, as the case may be, with such reduction and/or offset subject to a cap.

iQIYI 2025 Convertible Senior Notes

On March 29, 2019, iQIYI issued US$1.2

billion convertible senior notes (the “iQIYI 2025 Convertible Notes”). The iQIYI 2025 Convertible Notes are senior, unsecured obligations of iQIYI, and

interest is payable semi-annually in cash at a rate of 2.00% per annum on October 1 and April 1 of each year, beginning on

October 1, 2019

. The iQIYI 2025 Convertible Notes will mature on April 1, 2025 unless redeemed, repurchased or converted prior to such date.

The initial conversion rate of the iQIYI 2025 Convertible Notes is 33.0003 of iQIYI’s ADS per US$1,000 principal amount of the iQIYI 2025 Convertible Notes (which is equivalent to an initial conversion price of approximately US$30.30 per ADS). Prior to October 1, 2024, the iQIYI 2025 Convertible Notes will be convertible at the option of the holders only upon the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2019, if the last reported sale price of ADSs for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price; (2) during the five business day period after any ten consecutive trading day period in which the trading price per US$1,000 principal amount of notes was less than 98% of the product of the last reported sale price of the ADSs and the conversion rate on each such trading day; (3) if iQIYI calls the notes for a tax redemption; or (4) upon the occurrence of specified corporate events. Thereafter, the iQIYI 2025 Convertible Notes will be convertible at the option of the holders at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. The conversion rate is subject to adjustment in some events but is not adjusted for any accrued and unpaid interest. In addition, following a make-whole fundamental change that occurs prior to the maturity date or following iQIYI’s delivery of a notice of a tax redemption, iQIYI will increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event or such tax redemption. Upon conversion, iQIYI will pay or deliver to such converting holders, as the case may be, cash, ADSs, or a combination of cash and ADSs, at its election.

The holders may require iQIYI to repurchase all or a portion of the iQIYI 2025 Convertible Notes for cash on April 1, 2023, or upon a fundamental change, at a repurchase price equal to 100% of the principal amount, plus accrued and unpaid interest.

In connection with the issuance of the iQIYI 2025 Convertible Notes, iQIYI purchased capped call options (the “2025 Capped Call”) on iQIYI’s ADS with certain counterparties at a price of US$85 million. The counterparties agreed to sell to iQIYI up to approximately 40 million of iQIYI’s ADSs upon iQIYI’s exercise of the 2025 Capped Call. The exercise price is equal to the iQIYI 2025 Convertible Notes’ initial conversion price and the cap price is US$40.02 per ADS, subject to certain adjustments under the terms of the capped call transactions. The capped call transactions are expected to reduce potential dilution to existing holders of the ordinary shares and ADSs of iQIYI upon conversion of the iQIYI 2025 Convertible Notes and/or offset any potential cash payments that iQIYI is required to make in excess of the principal amount of any converted notes, as the case may be, with such reduction and/or offset subject to a cap.

iQIYI 2026 Convertible Senior Notes

On December 21, 2020, iQIYI issued US$800 million convertible senior notes and offered an additional US$100 million principal amount simultaneously, pursuant to the underwriters’ option to purchase additional notes. On January 8, 2021, the additional US$100 million principal amount was issued pursuant to the underwriters’ exercise of their option. The convertible senior notes issued on December 21, 2020 and January 8, 2021 (collectively referred to as the “iQIYI 2026 Convertible Notes”) are senior, unsecured obligations of iQIYI, and interest is payable semi-annually in cash at a rate of 4.00% per annum on June 15 and December 15 of each year, beginning on June 15, 2021. The iQIYI 2026 Convertible Notes will mature on December 15, 2026 unless redeemed, repurchased or converted prior to such date.

The initial conversion rate of the iQIYI 2026 Convertible Notes is 44.8179 of iQIYI’s ADS per US$1,000 principal amount of the iQIYI 2026 Convertible Notes (which is equivalent to an initial conversion price of approximately US$22.31 per ADS). Prior to June 15, 2026, the iQIYI 2026 Convertible Notes will be convertible at the option of the holders only upon the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on March 31, 2021, if the last reported sale price of ADSs for at least 20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price; (2) during the five business day period after any ten consecutive trading day period in which the trading price per US$1,000 principal amount of notes was less than 98% of the product of the last reported sale price of the ADSs and the conversion rate on each such trading day; (3) if iQIYI calls the notes for a tax redemption; or (4) upon the occurrence of specified corporate events. Thereafter, the iQIYI 2026 Convertible Notes will be convertible at the option of the holders at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. The conversion rate is subject to adjustment in some events but is not adjusted for any accrued and unpaid interest. In addition, following a make-whole fundamental change that occurs prior to the maturity date or following iQIYI’s delivery of a notice of a tax redemption, iQIYI will increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event or such tax redemption. Upon conversion, iQIYI will pay or deliver to such converting holders, as the case may be, cash, ADSs, or a combination of cash and ADSs, at its election.

The holders may require iQIYI to repurchase all or a portion of the iQIYI 2026 Convertible Notes for cash on August 1, 2024, or upon a fundamental change, at a repurchase price equal to 100% of the principal amount, plus accrued and unpaid interest.

iQIYI PAG Convertible Senior Notes

On December 30, 2022, iQIYI issued US$500

million convertible senior notes, pursuant to the definitive agreements entered into with PAGAC IV-1 (Cayman) Limited, PAG Pegasus Fund LP and/or their affiliates (collectively, the “Investors”) in August 2022. IQIYI also offered an additional

US$50 million principal amount simultaneously, pursuant to the Investors’ option to purchase additional notes. On February 24, 2023, the additional US$50

million principal amount was issued pursuant to the Investors’ exercise of their option. The convertible senior notes issued on December 30, 2022 and February 24, 2023 (collectively referred to as the “iQIYI PAG Convertible Notes”) are senior, secured obligations of iQIYI by certain collateral arrangements, and

interest is payable quarterly in cash at a rate of 6.00%

per annum on January 1, April 1, July 1 and October 1 of each year, beginning on April 1, 2023. The iQIYI PAG Convertible Notes will mature on the fifth anniversary of the issuance date unless redeemed, repurchased or converted prior to such date.

For the year ended December 31, 2023, the amount of interest cost recognized of iQIYI PAG Convertible Notes was RMB473 million (US$67 million). The repayments of iQIYI PAG Convertible Notes are guaranteed by equity interests of certain subsidiaries of iQIYI and collateralized by partial cash consideration related to certain contracts for which

million) cash consideration has been charged as of December 31, 2023 and recorded as long-term restricted cash. (Note 9).

iQIYI 2028 Convertible Senior Notes

Prior to September 15, 2027, the iQIYI 2028 Convertible Notes will be convertible at the option of the holders only upon the following circumstances: (1) during any calendar quarter commencing after the calendar quarter ending on June 30, 2023 (and only during such calendar quarter), if the last reported sale price of ADSs for at least

20 trading days (whether or not consecutive) during a period of 30 consecutive trading days ending on, and including, the last trading day of the immediately preceding calendar quarter is greater than or equal to 130% of the conversion price; (2) during the five business day period after any ten consecutive trading day period in which the trading price per US$1,000 principal amount of notes was less than 98%

Thereafter, the iQIYI 2028 Convertible Notes will be convertible at the option of the holders at any time until the close of business on the second scheduled trading day immediately preceding the maturity date. The conversion rate is subject to adjustment in some events but is not adjusted for any accrued and unpaid interest. In addition, following a make-whole fundamental change that occurs prior to the maturity date or following iQIYI’s delivery of a notice of a tax redemption, iQIYI will increase the conversion rate for a holder who elects to convert its notes in connection with such a corporate event or such tax redemption. Upon conversion, iQIYI will pay or deliver to such converting holders, as the case may be, cash, ADSs, or a combination of cash and ADSs, at its election.

Accounting for Convertible Senior Notes

The Group adopted ASU

No. 2020-06,

Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity

(“ASU

2020-06”)

by using a modified retrospective transition method through a cumulative-effect adjustment on January 1, 2022. After the adoption of ASU

2020-06,

as the iQIYI 2023 Convertible Notes, the iQIYI 2025 Convertible Notes, the iQIYI 2026 Convertible Notes, the iQIYI 2028 Convertible Notes and the iQIYI PAG Convertible Notes (collectively as the “iQIYI Notes”) were not issued at a substantial premium, all of the proceeds received from the issuance of the iQIYI Notes are recorded as a liability on the consolidated balance sheet in accordance with ASC

470-20.

That is, no portion of the proceeds from issuing the iQIYI Notes are attributed to the conversion option at inception. The difference between the principal amount of each of the iQIYI Notes and net proceeds from the issuance is considered debt discount and is amortized at their respective effective interest rates to accrete the carrying value of the iQIYI Notes to its face value

(

120

of the principal amount for iQIYI PAG Convertible Notes) on the respective put dates of the iQIYI Notes. For the year ended December 31, 2023, the effective interest rates of the iQIYI 2026 Convertible Notes, the iQIYI PAG Convertible Notes and the iQIYI 2028 Convertible Notes were

4.53

12.05

7.15

%, respectively.

The cost of the 2023 Capped Call and 2025 Capped Call of US$68 million and US$85

million were recorded as a reduction of the Company’s additional paid-in capital and non-controlling interests on the consolidated balance sheets with no subsequent changes in fair value recorded.

In 2023, the net proceeds from the issuance of the iQIYI 2028 Convertible Notes was

US$590 million, after deducting underwriting discounts and offering expenses of US$10 million from the initial proceeds of US$600 million.

In 2021 and 2023, iQIYI repurchased the iQIYI 2023 Convertible Notes and the iQIYI 2025 Convertible Notes with aggregate principal amount of US$

747

million and US$

1.2

billion (equivalent to RMB

8.5

billion), respectively, as requested by the holders. In 2023, iQIYI repurchased the iQIYI 2026 Convertible Notes and the iQIYI 2028 Convertible Notes with the aggregate principal amount of US$

504

million (equivalent to RMB

3.6

billion) and US$

million (equivalent to RMB

185

million), respectively, upon separate and individually privately negotiated agreements with certain holders. Following settlement of the repurchase, a difference between the net carrying amount of the repurchased iQIYI notes and the repurchased price was recognized as extinguishment gain and reported in “Others, net” in the consolidated statements of comprehensive income.

The carrying amount of the iQIYI Notes as of December 31, 2022 and 2023 were as follows:


	As of December 31,

As of December 31, 2023, the iQIYI 2026 Convertible Notes, iQIYI PAG Convertible Notes and iQIYI 2028 Convertible Notes will be accreted up to the principal amount of

US$396 million, US$660 million (120%

of the principal amount of iQIYI PAG Convertible Notes) and

US$574 million over a remaining period of 0.59 year, 2.00 years and 2.21 years, respectively. The amount repayable within the next twelve months are classified as “Convertible senior notes, current portion” on the consolidated balance sheets.

billion, respectively) of the iQIYI Notes will be repaid when they become due in 2025, 2026 and 2028, respectively, assuming there is no conversion of the iQIYI Notes, no redemption of the iQIYI Notes prior to their maturities, the convertible senior notes bondholders hold the iQIYI Notes until their maturities and iQIYI elects to fully settle the

Organization and Basis of Presentation

1.	ORGANIZATION AND BASIS OF PRESENTATION

Baidu, Inc. (“Baidu” or the “Company”) was incorporated under the laws of the Cayman Islands on January 18, 2000. The Company, its subsidiaries, variable interest entities (“VIEs”) and subsidiaries of the VIEs are hereinafter collectively referred to as the “Group”.

As of December 31, 2023, the Company has major subsidiaries incorporated in countries and jurisdictions including mainland China, Hong Kong, Cayman Islands and British Virgin Islands (“BVI”). As of December 31, 2023, the Company also effectively controls a number of VIEs through the Primary Beneficiaries, as defined below. The VIEs include:

•

Beijing Baidu Netcom Science Technology Co., Ltd. (“Baidu Netcom”), controlled by the Company;

•

Beijing Perusal Technology Co., Ltd. (“Beijing Perusal”), controlled by the Company;

•

Beijing iQIYI Science & Technology Co., Ltd. (“Beijing iQIYI”), and other VIEs controlled by iQIYI, Inc. (“iQIYI VIEs”); and

•

Other VIEs controlled by the Company or the Company’s subsidiaries.

The Group’s operations consist of Baidu Core and iQIYI. Baidu Core offers online marketing services, and other services including cloud services and other growth initiatives including intelligent driving, Xiaodu smart devices, etc. iQIYI is an innovative market-leading online entertainment service provider in China and offers membership services, online advertising services, content distribution and other services. iQIYI’s platform features iQIYI original content, as well as a comprehensive library of other professionally produced content (PPC), professional user generated content (PUGC) and user-generated content. The Group’s principal geographic market is in mainland China. The Company does not conduct any substantive operations of its own, but conducts its primary business operations through its subsidiaries incorporated in mainland China and contractual arrangements with the VIEs based in mainland China.

The Group’s internet content services, value-added telecommunication-based services, internet map services, online audio and video services, and mobile application distribution businesses in mainland China have been conducted through the applicable VIEs in order to comply with the laws and regulations of mainland China, which restrict and impose conditions on foreign direct investment in companies involved in the provision of such businesses. To comply with these foreign ownership restrictions, the Group operates its websites and primarily provides services subject to such restriction in mainland China through the VIEs, the mainland China legal entities that were established or whose equity shares were held by the individuals authorized by the Group.

The paid-in capital

of the VIEs was mainly funded by the Company or its subsidiaries through loans extended to the authorized individuals who were the shareholders of the VIEs. The Company or its subsidiaries has entered into proxy agreements/shareholder voting rights trust agreements/powers of attorney and exclusive equity purchase and transfer option agreement or exclusive purchase option agreement with the VIEs and nominee shareholders of the VIEs, which give the Primary Beneficiaries the power to direct the activities that most significantly affect the economic performance of the VIEs and to acquire the equity interests in the VIEs when permitted by the laws of mainland China, respectively. Certain exclusive agreements have been entered into with the VIEs through the Primary Beneficiaries or their wholly-owned subsidiaries in mainland China, which obligate the Primary Beneficiaries to absorb losses or receive economic benefits of the VIEs’ that could potentially be significant to the VIEs or entitle the Primary Beneficiaries to receive economic benefits from the VIEs that could potentially be significant to the VIEs. In addition, the Group has entered into certain agreements with the shareholders of the VIEs through the Primary Beneficiaries or their wholly-owned subsidiaries, including loan agreements for

the paid-in capital

of the VIEs and equity pledge agreements for the equity interests in the VIEs held by the shareholders of the VIEs.

The shareholders of the VIEs effectively assigned all of their voting rights underlying their equity interests in the VIEs to the Primary Beneficiaries. In addition, through the other exclusive agreements, which consist of exclusive equity purchase and transfer option agreements/exclusive purchase option agreements, commitment letters, operating agreements/business operation agreements, exclusive technology consulting and services agreements and license agreements, the Primary Beneficiaries, by themselves or their wholly-owned subsidiaries in mainland China, demonstrate their ability and intention to continue to exercise the ability to absorb losses or receive economic benefits that could potentially be significant to the VIEs. The VIEs are subject to operating risks, which determine the variability of the Company’s interest in those entities. Based on these contractual arrangements, the Company consolidates the VIEs as required by Accounting Standards Codification (“ASC”) Topic 810,

Consolidation

Unrecognized revenue-producing assets held by the VIEs include certain internet content provisions and other licenses, domain names and trademarks. The internet content provisions and other licenses, which are held by the VIEs that provide the relevant services, are required under the relevant laws of mainland China, rules and regulations for the operation of Internet businesses in mainland China, and therefore are integral to the Company’s operations.

Commitment Letters

Pursuant to the commitment letter dated January 30, 2013, under the condition that Beijing iQIYI remains as a consolidated variable interest entity of iQIYI under United States generally accepted accounting principles (“U.S. GAAP”) and the relevant contractual arrangements remain in effect, iQIYI commits to provide unlimited financial support to Beijing iQIYI, if Beijing iQIYI requires any form of reasonable financial support for its normal business operations. If Beijing iQIYI incurs any losses and as a result cannot repay its loans from iQIYI and Beijing QIYI Century, one of iQIYI’s subsidiaries, iQIYI and Beijing QIYI Century would unconditionally forgive their loans to Beijing iQIYI, if Beijing iQIYI provides sufficient proof for its loss and incapacity to repay.

The commitment letters executed by other iQIYI VIEs contain terms similar to the terms described above.

Through the contractual arrangements, the shareholders of the VIEs effectively assigned their full voting rights to the Company or its subsidiaries, which gives the Company or its subsidiaries the power to direct the activities that most significantly impact the VIEs’ economic performance. The Company or its subsidiaries obtain the ability to approve decisions made by the VIEs and the ability to acquire the equity interests in the VIEs when permitted by the laws of mainland China. The Company or its subsidiaries are obligated to absorb losses or receive economic benefits of the VIEs that could potentially be significant to the VIEs through providing unlimited financial support to the VIEs or are entitled to receive economic benefits from the VIEs that could potentially be significant to the VIEs through the exclusive technology consulting and service fees. As a result of these contractual agreements, the Company or its subsidiaries are determined to be the primary beneficiary of the VIEs and consolidates the VIEs as required by ASC Topic 810,

Consolidation

Through the contractual arrangements, the shareholders of the iQIYI VIEs effectively assigned all of their voting rights underlying their equity interests in iQIYI VIEs to iQIYI. In addition, through the other exclusive agreements, which consist of the operation agreements, business cooperating agreements, exclusive technology consulting and services agreements and trademark and software usage license agreements, iQIYI, through its wholly-owned subsidiaries in mainland China, have the right to receive economic benefits from iQIYI VIEs that potentially could be significant to iQIYI VIEs. Lastly, through the commitment letters, iQIYI has the obligation to absorb losses of iQIYI VIEs that could potentially be significant to iQIYI VIEs. Therefore, iQIYI is considered the primary beneficiary of iQIYI VIEs and consolidates iQIYI VIEs and their subsidiaries

In the opinion of the Company’s legal counsel, (i) the ownership structure relating to the VIEs of the Company is in compliance with the laws and regulations of mainland China; (ii) the contractual arrangements with the VIEs and their shareholders constituted legal, valid and binding obligations of such party, and are enforceable against such party in accordance with their respective terms; and (iii) the execution, delivery and performance by the VIEs and their shareholders, and the contractual arrangements as a whole, do not result in any violation of the provisions of the articles of association and business licenses of the VIEs, and any violation of any current laws and regulations of mainland China.

However, uncertainties in the PRC legal system could cause the Company’s current ownership structure to be found in violation of any existing and/or future laws or regulations of mainland China and could limit the Company’s ability, through the Primary Beneficiaries, to enforce its rights under these contractual arrangements. Furthermore, shareholders of the VIEs may have interests that are different with those of the Company, which could potentially increase the risk that they would seek to breach the existing terms of the aforementioned arrangements.

On January 1, 2020, the Foreign Investment Law came into effect and became the principal laws and regulations governing foreign investment in mainland China. The Foreign Investment Law does not explicitly classify

contractual arrangements as a form of foreign investment, but it contains a

catch-all

provision which includes investments made by foreign investors through means stipulated in laws or administrative regulations or other methods prescribed by the State Council. There are uncertainties regarding the interpretation of the Foreign Investment Law with respect to the contractual arrangements as a form of foreign investment. Since the VIEs’ internet content services, value-added telecommunication-based services, internet map services, online audio and video services and mobile application distribution businesses in mainland China are included in the negative list or subject to the restrictions on foreign investment, if any of the VIEs would be deemed as a foreign invested enterprise, the Company’s current organizational structure could be in violation of existing and/or future laws or regulations of mainland China and could limit the Company’s ability, through the Primary Beneficiaries, to enforce its rights under these contractual arrangements with the VIEs and the Company’s ability to conduct business through the VIEs could be severely limited.

In addition, if the current organizational structure or any of the contractual arrangements were found to be in violation of any existing and/or future laws or regulations of mainland China, the Company may be subject to penalties, which may include but not be limited to, the cancellation or revocation of the Company’s business and operating licenses, being required to restructure the Company’s operations or discontinue the Company’s operating activities. The imposition of any of these or other penalties may cause the Company to lose its right to direct the activities that most significantly impact the VIEs and/or the right to receive economic benefits that could potentially be significant to the VIEs based on the contractual arrangements, which may result in the Company no longer being able to consolidate the financial results of the VIEs in the consolidated financial statements.

Furthermore, shareholders of the VIEs may have interests that are different with those of the Company, which could potentially increase the risk that they would seek to breach the existing terms of the aforementioned agreements.

The following tables set forth the financial statement balances and amounts of the VIEs and their subsidiaries included in the consolidating financial statements after the elimination of intercompany balances and transactions among VIEs and their subsidiaries within the Group.

As of December 31, 2023, there was no pledge or collateralization of the VIEs’ assets that can only be used to settle obligations of the VIEs, other than aforementioned in the equity pledge agreements and collateralization of a VIE’s office building for iQIYI’s short-term loans (Note 13). The amount of the net assets of the VIEs was RMB30.5 billion (US$4.3 billion) as of December 31, 2023. The creditors of the VIEs’ third-party liabilities did not have recourse to the general credit of the Company in normal course of business. The Company did not provide financial or other supports not previously contractually required to the VIEs during the years presented.

Basis of Presentation

The consolidated financial statements are prepared in accordance with United States generally accepted accounting principles (“U.S. GAAP”).

Effective on March 1, 2021, each share of Class A ordinary shares, Class B ordinary shares and preferred shares of a par value of US$0.00005 each in the share capital of the Company (including authorized issued and unissued Class A ordinary shares, Class B ordinary shares and preferred shares)

was sub-divided into

80 shares of a par value of US$0.000000625 each (the “Share Subdivision”). Following the Share Subdivision, the authorized share capital of the Company became US$43,520 divided into 66,000,000,000 Class A ordinary shares of a par value of US$0.000000625 each, 2,832,000,000 Class B ordinary shares of a par value of US$0.000000625 each and 800,000,000 preferred shares of a par value of US$0.000000625 each. The number of issued and unissued Class A ordinary shares, Class B ordinary shares and preferred shares as disclosed elsewhere in the consolidated financial statements are presented on a basis after taking into account the effects of the Share Subdivision and have been retrospectively adjusted, where applicable. Simultaneously with the Share Subdivision, the change in ratio of the Company’s ADS to Class A ordinary share (the “ADS Ratio Change”) also became effective. Following the ADS Ratio Change, each ADS now represents eight Class A ordinary shares. Previously, ten ADSs represented one Class A ordinary share. Given that the ADS Ratio Change was exactly proportionate to the Share Subdivision, no new ADSs were issued to any ADS holder and the total number of the Company’s outstanding ADSs remains unchanged immediately after the Share Subdivision and the ADS Ratio Change became effective.

Summary Of Significant Accounting Policies [Line Items]

Principles of Consolidation

The consolidated financial statements include the financial statements of the Company, its subsidiaries, VIEs and subsidiaries of the VIEs. All inter-company transactions and balances between the Company, its subsidiaries,

VIEs and subsidiaries of the VIEs have been eliminated upon consolidation. The Group included the results of operations of the acquired businesses from their respective da

tes

of acquisition.

Comparative Information

Certain financial information of the Group’s equity method investees in Note 4, certain produced content related disclosures presented in Note 7 and certain iQIYI’s segment revenue related disclosures presented in Note 25 have been adjusted to conform with the current year’s presentation to facilitate comparison.

Use of Estimates

The preparation of the financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, and disclosures of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the period. Management evaluates estimates, including those related to the standalone selling prices of performance obligations and amounts of variable considerations of revenue contracts, the allowance for credit losses of accounts receivable, contract assets, receivables from online payment agencies, amounts due from related parties and debt securities, fair values of certain debt and equity investments, future viewership consumption patterns and useful lives of licensed copyrights and produced content, future revenues generated by the broadcasting and sublicensing rights of content assets (licensed and produced), ultimate revenue of produced content predominantly monetized on its own, fair values of licensed copyrights and produced contents monetized as a film group or individually, fair value of nonmonetary content exchanges, the useful lives of long-lived assets, impairment of long-lived assets, long-term investments and goodwill, the purchase price allocation, deferred tax valuation allowance, the fair value of share-based awards and estimated forfeitures for share-based awards among others. Management bases the estimates on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. Actual results could differ from these estimates.

Change in Accounting Estimate

In 2021, the Group reviewed and revised the estimated useful life of its servers from four years to five years. As a result of these revisions, depreciation expense decreased by RMB982 million, net income increased by RMB814 million, and basic and diluted net earnings per Class A and Class B ordinary share increased by RMB0.28 and RMB0.28, respectively, for the year ended December 31, 2021.

Currency Translation For Financial Statements Presentation

Currency Translation for Financial Statements Presentation

Translations of amounts from RMB into U.S. dollars (US$) for the convenience of the reader have been calculated at the exchange rate of RMB7.0999 per US$1.00 on December 29, 2023, the last business day in fiscal year 2023, as published on the website of the United States Federal Reserve Board. No representation is made that the RMB amounts could have been, or could be, converted into U.S. dollars at such rate.

Foreign Currency

The Company’s functional currency is the US$. The Company’s subsidiaries, VIEs and subsidiaries of the VIEs determine their functional currencies based on the criteria of ASC Topic 830,

Foreign Currency Matters

. The Group uses the RMB as its reporting currency. The Group uses the exchange rate as of the balance sheet date to translate its assets and liabilities and the average daily exchange rate for each month to translate its income and expense items to reporting currency. Any translation gains (losses) are recorded in other comprehensive (loss)

income. Transactions denominated in foreign currencies are measured and recorded into the functional currency at the exchange rates prevailing on the transaction dates. Assets and liabilities denominated in foreign currencies other than functional currency are remeasured into the functional currency at the exchange rates prevailing at the balance sheet date. Exchange gains and losses are included in earnings as a component of “Other income, net.”

Segment Reporting

As of December 31, 2022 and 2023, the Group had two reportable segments, Baidu Core and iQIYI. Baidu Core mainly provides search-based, feed-based and other online marketing services, cloud services, products and other services from its new AI initiatives. iQIYI is an online entertainment service provider that offers original, professionally produced and partner-generated content on its platform.

The Group’s chief executive officer, who has been identified as the chief operating decision maker (“CODM”), reviews the operating results of Baidu Core and iQIYI, to allocate resources and assess the Group’s performance. Accordingly, the financial statements include segment information which reflects the current composition of the reportable segments in accordance with ASC Topic 280,

Segment Reporting.

Business Combinations

The Group accounts for its business combinations using the acquisition method in accordance with ASC Topic 805,

Business Combinations

. The acquisition method requires that the consideration transferred to be allocated to the assets, including separately identifiable assets and liabilities the Group acquired, based on their estimated fair values. The consideration transferred in an acquisition is measured as the aggregate of the fair values at the date of exchange of the assets given, liabilities incurred, and equity instruments issued as well as the contingent considerations as of the acquisition date. The costs directly attributable to the acquisition are expensed as incurred. Identifiable assets, liabilities and contingent liabilities acquired or assumed are measured separately at their fair value as of the acquisition date, irrespective of the extent of any noncontrolling interests. The excess of (i) the total cost of acquisition, fair value of the noncontrolling interests and acquisition date fair value of any previously held equity interests in the acquiree over (ii) the fair value of the identifiable net assets of the acquiree, is recorded as goodwill. If the cost of acquisition is less than the fair value of the net assets of the subsidiary acquired, the difference is recognized directly in earnings.

In a business combination achieved in stages, the Group remeasures its previously held equity interest in the acquiree immediately before obtaining control at its acquisition-date fair value and the

re-measurement

gain or loss, if any, is recognized in “Others, net” in the consolidated statements of comprehensive income.

The determination and allocation of fair values to the identifiable assets acquired, liabilities assumed and noncontrolling interests are based on various assumptions and valuation methodologies requiring considerable judgment from management. The most significant variables in these valuations are discount rates, the number of years on which to base the cash flow projections, as well as the assumptions and estimates used to determine the cash inflows and outflows. The Group determines discount rates to be used based on the risk inherent in the related activity’s current business model and industry comparisons.

Cash and Cash Equivalents and Restricted Cash

Cash, Cash Equivalents and Restricted Cash

Cash and cash equivalents

Cash and cash equivalents primarily consist of cash, money market funds, investments in interest bearing demand deposit accounts, time deposits and highly liquid investments with original maturities of three months or less from the date of purchase and are stated at cost which approximates their fair value.

Restricted cash

Restricted cash mainly represents amounts deposited and held in escrow for the acquisition of YY Live, the share purchase agreement for which has been terminated on January 1, 2024, and restricted deposits used as security against convertible senior notes.

In the event that the obligation to maintain such restricted deposits is expected to be terminated within the next twelve months, these deposits will be classified as current assets, included in “Restricted cash” in the consolidated balance sheets. Otherwise, they will be classified as

non-current

assets, included in “Other

non-current

assets” in the consolidated balance sheets.

Accounts Receivable and Contract Asset, net

Accounts Receivable and Contract Assets, net

Accounts receivable are recognized and carried at the original invoiced amount less an allowance for credit losses. The Group’s right to consideration in exchange for goods or services that the Group has transferred to a customer is recognized as a contract asset. The Group maintains an allowance for credit losses in accordance with ASC Topic 326,

Credit Losses

(“ASC 326”) and records the allowance for credit losses as an offset to accounts receivable and contract assets, and the estimated credit losses charged to the allowance is classified as “Selling, general and administrative” in the consolidated statements of comprehensive income. The Group assesses collectability by reviewing accounts receivable and contract assets on a collective basis where similar characteristics exist, primarily based on similar business lines, services or product offerings and on an individual basis when the Group identifies specific customers with known disputes or collectability issues. In determining the amount of the allowance for credit losses, the Group considers historical collectability based on past due status, the age of the accounts receivable balances and contract assets balances, credit quality of the Group’s customers based on ongoing credit evaluations, current economic conditions, reasonable and supportable forecasts of future economic conditions, and other factors that may affect the Group’s ability to collect from customers.

Receivables from Online Payment Agencies, net

Receivables from online payment agencies are funds due from the third-party online payment service providers for clearing transactions and are included in “Other current assets, net” on the consolidated balance sheets. The cash was paid or deposited by customers or users through these online payment agencies for services provided by the Group. The Group considers and monitors the credit worthiness of the third-party payment service providers and recognizes credit losses based on ongoing credit evaluations. Receivable balances are written off when they are deemed uncollectible. As of December 31, 2022 and 2023, allowance for credit losses provided for the receivables from online payment agencies were insignificant.

Investments

Short-term

investments

All highly liquid investments with original maturities less than twelve months are classified as short-term investments. Investments that are expected to be realized in cash during the next twelve months are also included in short-term investments.

The Group accounts for short-term debt investments in accordance with ASC Topic 320,

Investments – Debt Securitie

s (“ASC 320”)

The Group classifies the short-term investments in debt securities as

held-to-maturity,

trading or

available-for-sale,

whose classification determines the respective accounting methods stipulated by ASC 320. Dividend and interest income, including amortization of the premium and discount arising at

acquisition, for all categories of investments in securities are included in earnings. Any realized gains or losses on the sale of the short-term investments are determined on a specific identification method, and such gains and losses are reflected in earnings during the period in which gains or losses are realized.

Securities that the Group has the positive intent and ability to hold to maturity are classified as

held-to-maturity

securities and stated at amortized cost less allowance for credit losses.

Securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities, in accordance with ASC 320. Unrealized holding gains and losses for trading securities are included in earnings.

Debt investments not classified as trading or as

held-to-maturity

are classified as

available-for-sale

debt securities, which are reported at fair value, with unrealized gains and losses recorded in “Accumulated other comprehensive income (loss)” on the consolidated balance sheets.

The allowance for credit losses of the

held-to-maturity

debt securities reflects the Group’s estimated expected losses over the contractual lives of the

held-to-maturity

debt securities and is charged to “Others, net” in the consolidated statements of comprehensive income. Estimated allowance for credit losses is determined by considering reasonable and supportable forecasts of future economic conditions in addition to information about past events and current conditions. As of December 31, 2022 and 2023, the allowance for credit losses provided for the

held-to-maturity

debt securities held by the Group was RMB277 million and RMB385 million (US$54 million), respectively.

Long-term investments

The Group’s long-term investments consist of equity method investments, equity investments with readily determinable fair value, equity investments without readily determinable fair value, equity investments in private equity funds, other investments accounted for at fair value and

available-for-sale

debt investments.

Investments in entities in which the Group can exercise significant influence but does not own a majority equity interest or control are accounted for using the equity method of accounting in accordance with ASC Topic 323,

Investments-Equity Method and Joint Ventures

(“ASC 323”). Under the equity method, the Group initially records its investment at cost and the difference between the cost of the equity investee and the amount of the underlying equity in the net assets of the equity investee is accounted for as if the investee were a consolidated subsidiary. The Group subsequently adjusts the carrying amount of its investment to recognize the Group’s proportionate share of each equity investee’s net income or loss into earnings after the date of investment and its share of each equity investee’s movement in accumulated other comprehensive income or loss is recognize in other comprehensive (loss) income. When calculating its proportionate share of each equity investee’s net income or loss, the Group adjusts the net income or loss of equity investee to include accretion of preferred stock that is classified in temporary equity in the investee’s financial statements, into earnings. The Group will discontinue applying the equity method if an investment (plus additional financial support provided to the investee, if any) has been reduced to zero. When the Group has other investments in its equity-method investee and is not required to advance additional funds to that investee, the Group would continue to report its share of equity method losses in its consolidated statements of comprehensive income after its equity-method investment in ordinary shares has been reduced to zero, to the extent of and as an adjustment to the adjusted basis of the Group’s other investments in the investee. Such losses are first applied to those investments of a lower liquidation preference before being further applied to the investments of a higher liquidation preference. The Group adopted a

one-quarter

lag in reporting for its share of equity income/(loss) to a majority of its equity method investees.

The Group evaluates its equity method investments for impairment at each reporting date, or more frequently if events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable. Factors considered by the Group when determining whether an investment has been other-than-temporarily-impaired, include, but are not limited to, the length of the time and the extent to which the market value has been less than cost, the financial condition and near-term prospects of the investee, and the Group’s intent and ability to retain the investment until the recovery of its cost. An impairment loss on the equity method investments is recognized in earnings when the decline in value is determined to be other-than-temporary and is allocated to the individual net assets underlying equity method investments in the following order: 1) reduce any equity method goodwill to zero; 2) reduce the individual basis differences related to the investee’s long-lived assets pro rata based on their amounts relative to the overall basis difference at the impairment date; and 3) reduce the individual basis difference of the investee’s remaining assets in a systematic and rational manner.

For equity investments in private equity funds, over which the Group does not have the ability to exercise significant influence, are measured using the net asset value per share based on the practical expedient in ASC Topic 820,

Fair Value Measurements and Disclosures

(“ASC 820”) (“NAV practical expedient”).

For equity securities without readily determinable fair value and do not qualify for the NAV practical expedient, the Group elects to use the measurement alternative to measure those investments at cost, less any impairment, plus or minus changes resulting from observable price changes in orderly transactions for identical or similar investments of the same issuer, if any. Significant judgments are required to determine (i) whether observable price changes are orderly transactions and identical or similar to an investment held by the Group; and (ii) the selection of appropriate valuation methodologies and underlying assumptions, including expected volatility and the probability of exit events as it relates to liquidation and redemption features used to measure the price adjustments for the difference in rights and obligations between instruments. Equity securities with readily determinable fair values are measured at fair value, and any changes in fair value are recognized in “Others, net” in the consolidated statements of comprehensive income.

For equity investments measured at fair value with changes in fair value recorded in earnings, the Group does not assess whether those securities are impaired. For equity investments that the Group elects to use the measurement alternative, the Group makes a qualitative assessment considering impairment indicators to evaluate whether investments are impaired at each reporting date. Impairment indicators considered include, but are not limited to, a significant deterioration in the earnings performance or business prospects of the investee, including factors that raise significant concerns about the investee’s ability to continue as a going concern, a significant adverse change in the regulatory, economic, or technologic environment of the investee and a significant adverse change in the general market condition of either the geographical area or the industry in which the investee operates. If a qualitative assessment indicates that the investment is impaired, the entity has to estimate the investment’s fair value in accordance with the principles of ASC 820. If the fair value is less than the investment’s carrying value, the Group recognizes an impairment loss in earnings equal to the difference between the carrying value and fair value.

In accordance with ASC Subtopic

946-320,

Financial Services—Investment Companies, Investments—Debt and Equity Securities

(“ASC

946-320”)

the Group’s consolidated investment company accounts for long-term equity investments in unlisted companies at fair value. These investments were initially recorded at their transaction price net of transaction costs, if any. Fair values of these investments are

re-measured

at each reporting date in accordance with ASC 820.

Available-for-sale

debt investments are convertible debt instruments issued by private companies and investments in preferred shares that are currently redeemable at the Group’s option, which are measured at fair

value. Interest income is recognized in earnings. All other changes in the carrying amount of these debt investments are recognized in other comprehensive (loss) income.

Long-term time deposits and

held-to-maturity

investments

Long-term time deposits and

held-to-maturity

securities are mainly deposits in commercial banks and wealth management products issued by commercial banks and other financial institutions with maturities of greater than one year.

Investments in debt securities with maturities of greater than one year that the Group has positive intent and ability to hold to maturity are classified as long-term

held-to-maturity

investments and stated at amortized cost less allowance for credit losses.

Fair Value Measurements of Financial Instruments

Financial instruments include cash and cash equivalents, restricted cash, short-term investments, amounts due from and due to related parties, other receivables and long-term investments. The carrying values of the aforementioned financial instruments included in current assets and liabilities approximate their respective fair values because of their general short maturities. The carrying amounts of long-term loans approximate fair values as the related interest rates currently offered by financial institutions for similar debt instruments of comparable maturities. The fair value of long-term investments, notes payable and convertible senior notes that are not reported at fair value are disclosed in Note 26.

Fixed Assets

Fixed assets are stated at cost less accumulated depreciation. Depreciation is recorded on a straight-line basis over the shorter of the estimated useful lives of the assets or the term of the related lease, as follows:


Office building		– 43 to 45 years
Office building related facility, machinery and equipment		– 10 to 15 years
Computer equipment		– 3 to 5 years
Office equipment		– 3 to 5 years
Vehicles		– 5 years
Leasehold improvements		– over the shorter of lease terms or estimated useful lives of the assets

Fixed assets have no estimated residual value except for the office building and its related facility, machinery and equipment, which mainly have an estimated residual value of 4% of the cost.

Repair and maintenance costs are charged to expense as incurred, whereas the cost of renewals and betterments that extend the useful life of fixed assets are capitalized as additions to the related assets. Retirements, sales and disposals of assets are recorded by removing the cost and accumulated depreciation from the asset and accumulated depreciation accounts with any resulting gain or loss reflected in earnings. All direct and indirect costs that are related to the construction of fixed assets and incurred before the assets are ready for their intended use are capitalized as construction in progress. Construction in progress is transferred to specific fixed assets items and depreciation of these assets commences when they are ready for their intended use.

Interest costs are capitalized if they are incurred during the acquisition, construction or production of a qualifying asset and such costs could have been avoided if expenditures for the assets have not been made. Capitalization of interest costs commences when the activities to prepare the asset are in progress and expenditures and borrowing costs are being incurred. Interest costs are capitalized until the assets are ready for their intended use. Interest costs capitalized for the years ended December 31, 2021, 2022 and 2023 were insignificant.

Licensed Copyrights, net

Licensed copyrights consist of professionally-produced content such as films, drama series, variety shows and other video content acquired from external parties. The license fees are capitalized and, unless prepaid, a corresponding liability is recorded when the cost of the content is known, the content is accepted by the Group in accordance with the conditions of the license agreement and the content is available for its first showing on the Group’s platforms. Licensed copyrights are presented on the consolidated balance sheets as current and

non-current

based on estimated time of usage.

The Group’s licensed copyrights include the right to broadcast and, in some instances, the right to sublicense. The broadcasting right, refers to the right to broadcast the content on its own platforms and the sublicensing right, refers to the right to sublicense the underlying content to external parties. When licensed copyrights include both broadcasting and sublicensing rights, the content costs are allocated to these two rights upon initial recognition, based on the relative proportion of the estimated total revenues that will be generated from each right over its estimated useful lives.

For the right to broadcast the contents on its own platforms that generates online advertising and membership services revenues, the content costs are amortized based on factors including historical and estimated future viewership patterns, using an accelerated method by content categories over the shorter of each content’s contractual period or estimated useful lives within ten years, beginning with the month of first availability. Content categories accounting for most of the Group’s content include newly released drama series, newly released films, animations, library drama series and library films. Estimates of future viewership consumption patterns and estimated useful lives are reviewed periodically, at least on an annual basis and revised, if necessary. Revisions to the amortization patterns are accounted for as a change in accounting estimate prospectively in accordance with ASC Topic 250,

Accounting Changes and Error Corrections

(“ASC 250”). For the right to sublicense the content to external parties that generates direct content distribution revenues, the content costs are amortized based on its estimated usage pattern and recorded as cost of revenues.

Produced Content, net

The Group produces original content

in-house

and in collaboration with external parties. Produced content primarily consists of films, episodic series, variety shows and animations. The costs incurred in the physical production of original content include direct production costs, production overhead and acquisition costs. Produced content also includes cash expenditures made to acquire a proportionate share of certain rights to films including profit sharing, distribution and/or other rights. Exploitation costs are expensed as incurred. Participation costs are accrued using the individual-film-forecast-computation method, which recognizes the costs in the same ratio as the associated ultimate revenue. Production costs for original content that are predominantly monetized in a film group are capitalized. Production costs for original content that are predominantly monetized on its own are capitalized to the extent that they are recoverable from total revenues expected to be earned (“ultimate revenue”); otherwise, they are expensed as cost of revenues. Ultimate revenue estimates include revenue expected to be earned from all sources, including exhibition, licensing, or exploitation of produced content if the Group has demonstrated a history of earning such revenue. The Group estimates

ultimate revenue to be earned during the estimated useful lives of produced content based on anticipated release patterns and historical results of similar produced content, which are identified based on various factors, including cast and crew, target audience and popularity. The capitalized production costs are reported separately as noncurrent assets with caption of “Produced content, net” on the consolidated balance sheets. Based on factors including historical and estimated future viewership consumption patterns, the Group amortizes produced content that is predominantly monetized in a film group. For produced content that is monetized on its own, the Group considers historical and estimated usage patterns to determine the pattern of amortization. Based on the estimated patterns, the Group amortizes produced content using an accelerated method over its estimated useful lives within ten years, beginning with the month of first availability and such costs are included in “Cost of revenues” in the consolidated statements of comprehensive income.

Impairment of licensed copyrights and produced contents

Impairment of licensed copyrights and produced content

The Group’s business model is mainly subscription and advertising based, as such the majority of the Group’s content assets (licensed copyrights and produced content) are predominantly monetized with other content assets, whereas a smaller portion of the Group’s content assets are predominantly monetized at a specific title level such as variety shows and investments in a proportionate share of certain film rights including profit sharing, distribution and/or other rights. Because the identifiable cash flows related to content launched on the Group’s Mainland China platform are largely independent of the cash flows of other content launched on the Group’s overseas platform, the Group has identified two separate film groups. The Group reviews its film groups and individual content for impairment when there are events or changes in circumstances that indicate the fair value of a film group or individual content may be less than its unamortized costs. Examples of such events or changes in circumstances include, a significant adverse change in technological, regulatory, legal, economic, or social factors that could affect the fair value of the film group or the public’s perception of a film or the availability of a film for future showings, a significant decrease in the number of subscribers or forecasted subscribers, or the loss of a major distributor, a change in the predominant monetization strategy of a film that is currently monetized on its own, actual costs substantially in excess of budgeted costs, substantial delays in completion or release schedules, or actual performance subsequent to release failing to meet expectations set before release such as a significant decrease in the amount of ultimate revenue expected to be recognized.

When such events or changes in circumstances are identified, the Group assesses whether the fair value of an individual content (or film group) is less than its unamortized film costs, determines the fair value of an individual content (or film group) and recognizes an impairment charge for the amount by which the unamortized capitalized costs exceed the individual content’s (or film group’s) fair value. The Group mainly uses a discounted cash flow approach to determine the fair value of an individual content or film group, of which the most significant inputs include the forecasted future revenues, costs and operating expenses attributable to an individual content or the film group and the discount rate. An impairment loss attributable to a film group is allocated to individual licensed copyrights and produced content within the film group on a pro rata basis using the relative carrying values of those assets as the Group cannot estimate the fair value of individual contents in the film group without undue cost and effort.

Goodwill and Intangible Assets

Goodwill

Goodwill represents the excess of the purchase price over the fair value of the identifiable net assets acquired in a business combination. The Group assesses goodwill for impairment in accordance with ASC Subtopic

350-20,

Intangibles—Goodwill and Other: Goodwill

(“ASC

350-20”),

which requires goodwill to be tested for

impairment at the reporting unit level at least annually and more frequently upon the occurrence of certain events, as defined by ASC

350-20.

As of December 31, 2022 and 2023, the Group has three reporting units, consisting of Baidu Core excluding Smart Living Group (“SLG”), SLG and iQIYI.

The Group has the option to assess qualitative factors first to determine whether it is necessary to perform the quantitative test in accordance with ASC

350-20.

In the qualitative assessment, the Group considers primary factors such as industry and market considerations, overall financial performance of the reporting unit, and other specific information related to the operations. If the Group believes, as a result of the qualitative assessment, that it is

more-likely-than-not

that the fair value of the reporting unit is less than its carrying amount, the quantitative impairment test described above is required. Otherwise, no further testing is required. The quantitative impairment test compares the fair value of the reporting unit with its carrying amount, including goodwill. If the carrying amount of a reporting unit exceeds its fair value, an impairment loss shall be recognized in an amount equal to that excess.

The Group performed qualitative assessments for the reporting unit of Baidu Core excluding SLG in 2022 and 2023. Based on the requirements of ASC

350-20,

the Group evaluated all relevant factors including, but not limited to, macroeconomic conditions, industry and market conditions, financial performance, and the share price of the Group.

Due to the changing market conditions and fluctuations in the share price of the Group, the Group performed quantitative assessment for the reporting unit of Baidu Core excluding SLG in 2022 and 2023. The Group estimated fair value using the income approach and the market approach. The fair value determined using the income approach was compared with comparable market data and reconciled, as necessary. No impairment loss of goodwill related to the reporting unit of Baidu Core excluding SLG was recorded for the years ended December 31, 2022 and 2023.

The Group performed qualitative assessments for the reporting unit of SLG in 2022 and 2023. Based on the requirements of ASC

350-20,

the Group evaluated all relevant factors including, but not limited to, macroeconomic conditions, industry and market conditions, financial performance, and the share price of the Group. The Group weighed all factors in their entirety and concluded that it was not

more-likely-than-not

the fair value was less than the carrying amount of SLG, and further impairment testing on goodwill was unnecessary as of December 31, 2022 and 2023.

The Group elected to bypass the qualitative assessment and proceeded directly to perform a quantitative test for the reporting unit of iQIYI. The Group primarily considers the quoted market price of iQIYI’s ordinary shares to determine the fair value of the reporting unit. As of December 31, 2022 and 2023, the fair value of iQIYI exceeded its carrying amount, therefore, goodwill related to the iQIYI reporting unit was not impaired and the Group was not required to perform further testing.

Application of a goodwill impairment test requires significant management judgment and estimation, such as identification of reporting units, estimating the fair value of each reporting unit. Estimating the fair value of reporting units using income approach and market approach involved significant assumptions, such as revenue growth rates, profitability in estimating future cash flows, discount rates, earnings multipliers based on market data of comparable companies engaged in a similar business. Changes in these assumptions could materially affect the determination of fair value for each reporting unit.

On disposal of a portion of reporting unit that constitutes a business, the attributable amount of goodwill is included in the determination of the amount of gain or loss recognized upon disposal. When the Group disposes

of a business within the reporting unit, the amount of goodwill disposed is measured on the basis of the relative fair value of the business disposed and the portion of the reporting unit retained.

Intangible assets

Intangible assets with finite lives are carried at cost less accumulated amortization. All intangible assets with finite lives are amortized using the straight-line method over their estimated useful lives.

Intangible assets have weighted average useful lives from the date of purchase as follows:


Trademarks		– 11 years
Technology		– 5 years
Intellectual property right		– 8 years
Online literature		– 9 years
Others		– 13 years

Intangible assets with indefinite useful life are not amortized and are tested for impairment annually or more frequently, if events or changes in circumstances indicate that they might be impaired in accordance with ASC Subtopic

350-30,

Intangibles-Goodwill and Other: General Intangibles Other than Goodwill

(“ASC

350-30”).

Impairment of Long-Lived Assets Other Than Goodwill

The Group evaluates long-lived assets, such as fixed assets and purchased or internally developed intangible assets with finite lives other than licensed copyrights and produced content, for impairment whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable in accordance with ASC Topic 360,

Property, Plant and Equipment

. When such events occur, the Group assesses the recoverability of the asset group based on the undiscounted future cash flows the asset group is expected to generate and recognizes an impairment loss when estimated undiscounted future cash flows expected to result from the use of the asset group plus net proceeds expected from disposition of the asset group, if any, is less than the carrying value of the asset group. If the Group identifies an impairment, the Group reduces the carrying amount of the asset group to its estimated fair value based on a discounted cash flow approach or, when available and appropriate, to comparable market values and the impairment loss, if any, is recognized in “Cost of revenues” in the consolidated statements of comprehensive income. The Group uses estimates and judgments in its impairment tests and if different estimates or judgments had been utilized, the timing or the amount of any impairment charges could be different. Asset groups to be disposed of would be reported at the lower of the carrying amount or fair value less costs to sell, and no longer depreciated. The assets and liabilities of a disposal group classified as held for sale would be presented separately in the appropriate asset and liability sections of the consolidated balance sheets.

Leases

The Group has lease agreements with lease and

non-lease

components, which are generally accounted for separately. The Group elected the short-term lease exemption for all contracts with lease terms of 12 months or less.

The Group determines if an arrangement is a lease or contains a lease at lease inception. For operating leases, the Group recognizes an ROU asset and a lease liability based on the present value of the lease payments over the lease term on the consolidated balance sheets at commencement date. For finance leases, assets are included in

“Other

non-current

assets” on the consolidated balance sheets. As the implicit rates of most of the Group’s leases are not readily determinable, the Group estimates its incremental borrowing rate based on the information available at the commencement date in determining the present value of lease payments. The incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in economic environments where the leased asset is located. The Group’s leases often include options to extend and lease terms include such extended terms when the Group is reasonably certain to exercise those options. Lease terms also include periods covered by options to terminate the leases when the Group is reasonably certain not to exercise those options. Lease expense is recorded on a straight-line basis over the lease term.

Revenue Recognition

The Group’s revenues are derived principally from online marketing service and others. Revenue is recognized when control of promised goods or services is transferred to the Group’s customers in an amount of consideration to which an entity expects to be entitled to in exchange for those goods or services. Revenue is recorded net of valued added taxes (“VAT”).

For arrangements that include multiple promised goods or services, the Group would evaluate all of the performance obligations in the arrangement to determine whether each performance obligation is distinct. For arrangements with multiple distinct performance obligations, each distinct performance obligation is separately accounted for and the total consideration is allocated to each performance obligation based on their relative standalone selling price at contract inception. The Group generally determines standalone selling prices based on the prices charged to customers on a standalone basis or estimates it using an expected cost plus margin approach. For arrangement with multiple components that are not distinct within the context of the contract because they have significant integration and the customer can only benefit from these promised goods or services in conjunction with one another, the Group accounts for them as one performance obligation.

The Group’s revenue recognition policies by types are as follows:

Online marketing services

Performance-based online marketing services

The Group’s

pay-for-performance

(“P4P”) platform enables customers to bid for priority placement of paid sponsored links and reach users who search for information related to their products or services. P4P online marketing customers can choose from search-based and feed-based online marketing services, and select criteria for their purchase, such as daily spending limit and user profile targeted. Revenue is recognized when all of the revenue recognition criteria are met, which is generally when a user clicks on one of the customer-sponsored links or feed-based marketing.

To the extent the Group provides online marketing services based on performance criteria other than

cost-per-click

(“CPC”), revenue is recognized when the specified performance criteria are met along with the satisfaction of other applicable revenue recognition criteria.

Baidu Union online marketing services

Baidu Union is a program through which the Group expands distribution of its customers’ sponsored links or advertisements by leveraging the traffic of Baidu Union partners’ online properties. The Group acquires traffic

from Baidu Union partners and is responsible for service fulfillment and pricing. The services which the Group provided to customers through Baidu Union partners’ online properties include CPC, other performance-based online marketing services and online display advertising services. These services are provided in the same way to customers as those through Baidu’s own platforms or properties. As the principal, the Group recognizes revenue from Baidu Union on a gross basis. Payments made to Baidu Union partners are recorded as traffic acquisition costs, which are included in “Cost of revenues” in the consolidated statements of comprehensive income.

Online display advertising services

The Group provides online display advertising services to its customers by integrating text description, image and/or video, and displaying the advertisement in the search result, in Baidu Feed or on other properties. The Group recognizes revenue on a

pro-rata

basis over the contractual term for cost per time advertising arrangements, commencing on the start date of the display advertisement, or based on the number of times that the advertisement has been displayed for cost per thousand impressions advertising arrangements.

Collection

Certain customers of online marketing services are required to pay a deposit before using the Group’s services and are sent automated reminders to replenish their accounts when the balance falls below a designated amount. The deposits received are recorded as “Customer deposits and deferred revenue” on the consolidated balance sheets. The amounts due to the Group are deducted from the deposited amounts when users click on the paid sponsored links in the search results or other performance criteria have been satisfied. In addition, the Group offers payment terms to third-party agents and advertisers based on their historical marketing placements and credibility, consistently with industry practice.

Payment terms and conditions vary by customer and are based on the billing schedule established in the Group’s contracts or purchase orders with customers, but the Group generally provides credit terms to customers within one year; therefore, the Group has determined that its contracts do not include a significant financing component.

Sales incentives

The Group provides major sales incentives to third-party agents, which are identified as customers, that entitle them to receive price reductions on the online marketing services by meeting certain cumulative consumption requirements. The Group accounts for these incentives granted to customers as variable consideration and net them against revenue. The amount of variable consideration is measured based on the expected value of incentives to be provided to customers.

Others

Video Membership services

The Group offers membership services to subscribing members with various privileges, which primarily include access to exclusive and

ad-free

streaming of premium content 1080P/4K high-definition video, eXave Max, Dolby Audio, and accelerated downloads and others. When the receipt of membership fees is for services to be delivered over a period of time, the receipt is initially recorded as “Customer deposits and deferred revenue” and revenue is recognized ratably over the membership period as services are rendered. Membership services revenue also includes fees earned from subscribing members for

on-demand

content purchases and early access to premium content. The Group is the principal in its relationships where partners, including consumer electronics

manufacturers (TVs and cell phones), mobile operators, internet service providers and online payment agencies, provide access to the membership services or payment processing services as the Group retains control over its service delivery to its subscribing members. Typically, payments made to the partners, are recorded as cost of revenues. For the sale of the right to other membership services through strategic cooperation with other parties, the Group recognizes revenue on a net basis when the Group does not control the specified services before they are transferred to the customer.

Content distribution

The Group generates revenues from

sub-licensing

content assets within its authorized scope for cash or through nonmonetary exchanges mainly with other online video broadcasting companies, as well as from the release of feature films for exhibition in theaters. For cash

sub-licensing

transactions, the Group is entitled to receive the

sub-license

fee under the

sub-licensing

arrangements and does not have any future obligation once it has provided the underlying content to the

sub-licensee

(which is provided at or before the beginning of the

sub-license

period). The

sub-licensing

of content assets represents a license of functional intellectual property which grants a right to use the Group’s content assets, and is recognized at the point in time when the content asset is made available for the customer’s use and benefit.

The Group also enters into nonmonetary transactions to exchange online broadcasting rights of content assets with other online video broadcasting companies from time to time. The exchanged content assets provide rights for each party to broadcast the content assets received on its own platform only. Each transferring party retains the right to continue broadcasting the exclusive content on its own platform and/or sublicense the rights to the content it surrendered in the exchange. The Group accounts for these nonmonetary exchanges based on the fair value of the asset received. Barter revenues are recognized in accordance with the same revenue recognition criteria above. The Group estimates the fair value of the content assets received using a market approach based on various factors, including the purchase price of similar

non-exclusive

and/or exclusive contents, broadcasting schedule, cast and crew, theme, popularity, and box office. The transaction price of barter transaction is calculated on an individual content asset basis. For a significant barter transaction, the Group further reviews the fair value by analyzing against the cost of the content assets bartered out and/or engages a third-party valuation firm to assess the reasonableness of its fair value. The attributable cost of sublicensing transactions, whether for cash or through nonmonetary exchanges, is recognized as cost of revenues through the amortization of the sublicensing right component of the exclusive content assets.

Cloud service

The Group provides enterprise and public sector cloud services and personal cloud services, generally on either a subscription or consumption basis. For enterprise and public sector cloud services, the Group offers a full suite of cloud services and solutions, including IaaS (infrastructure as a service), PaaS (platform as a service), and SaaS (software as a service). For personal cloud services, the Group offers Baidu Drive membership services provided to individual customers. Revenue related to enterprise and public sector cloud services provided on a subscription basis is recognized ratably over the contract period. Revenue related to enterprise and public sector cloud services provided on a consumption basis, such as the amount of storage used in a period, is recognized based on the customer’s utilization of such resources. Revenue related to personal cloud services is recognized ratably over the membership period as services are rendered, and the receipt of membership fees for services to be delivered over a period of time is initially recorded as “Customer deposits and deferred revenue”.

The Group provides cloud solutions for customers in specific industries, such as smart transportation, finance, manufacturing, energy, telecom and media. Revenue related to cloud solutions, which mainly include significant

integrated hardware, software licensing and installation service, is recognized over time if one of the following criteria is met: (i) the customer simultaneously receives and consumes the benefits as the Group performs; (ii) the Group’s performance creates or enhances an asset that the customer controls as the asset is created or enhanced; or (iii) the asset delivered has no alternative use and the Group has an enforceable right to payment for performance completed to date. For performance obligations satisfied over time, the Group recognizes revenue over time by measuring the progress toward complete satisfaction of a performance obligation. Otherwise, revenue is recognized at a point in time when a customer obtains control of a promised asset or service and the Group satisfies its performance obligation.

Baidu Apollo auto solutions

Revenue related to Baidu Apollo auto solutions (Apollo Self-Driving services and DuerOS for Auto), which mainly includes software licensing, are recognized when earned in accordance with the terms of the underlying agreement. Generally, revenue is recognized at a point in time when the intellectual property is made available for the customer’s use and benefit.

Sales of hardware

The Group mainly sells Xiaodu smart device hardware products via third-party agents or directly to end customers. Revenue from the sales of hardware is recognized when control of the goods is transferred to customers, which generally occurs when the products are delivered and accepted by the customers. Revenue is recorded net of sales incentives and return allowance.

Contract assets and contract liabilities

Payment terms and conditions vary by customer and are based on the billing schedule established in the Group’s contracts or purchase orders with customers, although terms generally include a requirement of payment within one year.

Timing of revenue recognition may differ from the timing of invoicing to customers. For certain services, customers are required to pay before the services are delivered to the customer. When either party to a revenue contract has performed, the Group recognizes a contract asset or a contract liability on the consolidated balance sheets, depending on the relationship between the entity’s performance and the customer’s payment.

Contract liabilities were mainly related to fees for membership services to be provided over the membership period, which were included in “Customer deposits and deferred revenue” on the consolidated balance sheets. Balances of contract liabilities were RMB6.8 billion and RMB7.9 billion (US$1.1 billion) as of December 31, 2022 and 2023, respectively. Revenue recognized for the year ended December 31, 2023 that was included in contract liabilities as of January 1, 2023 was RMB5.9 billion (US$832 million). As of December 31, 2023, the increase in the balance of contract liabilities was primarily due to more consideration received from membership services compared to the prior year.

Contract assets mainly represent unbilled amounts related to the Group’s rights to consideration for advertising services and cloud services delivered and are included in “Other current assets, net” on the consolidated balance sheets. As of December 31, 2022 and 2023, contract assets were RMB3.4 billion and RMB3.3 billion (US$459 million), net of an allowance for credit losses of RMB285 million and RMB168 million (US$24 million), respectively.

As of December 31, 2023, total transaction price allocated to performance obligations that were unsatisfied or partially unsatisfied for contracts with an original expected length of more than one year was RMB2.3 billion (US$319 million), which is expected to be recognized over the next two years.

The Group does not disclose the value of unsatisfied performance obligations for (i) contracts with an original expected length of one year or less and (ii) contracts for which the Group recognizes revenue at the amount to which it has the right to invoice for services performed.

The Group’s disaggregated revenue disclosures are presented in Note 25.

Cost of Revenues

Cost of revenues consists primarily of traffic acquisition costs, bandwidth costs, depreciation, content costs, payroll, cost of hardware sold and other operational costs.

Traffic acquisition costs mainly represent the amounts paid or payable to Baidu Union partners who direct search queries to the Group’s websites or distribute the Group’s customers’ paid links through their properties. These payments are primarily based on revenue sharing arrangements under which the Group pays its Baidu Union partners and other business partners a percentage of the fees it earns from its online marketing customers.

Advertising, Marketing and Promotional Expenses

Advertising, marketing and promotional expenses, including advertisements through various forms of media and kinds of marketing and promotional activities, are included in “Selling, general and administrative” in the consolidated statements of comprehensive income and are expensed when incurred. Advertising, marketing and promotional expenses for the years ended December 31, 2021, 2022 and 2023 were RMB12.2 billion, RMB10.2 billion and RMB13.2 billion (US$1.9 billion), respectively.

Research and Development Expenses

Research and development expenses consist primarily of personnel-related costs. The Group expenses research and development costs as they are incurred, except for (i) costs to develop

internal-use

software or add significant upgrades and enhancements resulting in additional functionality to

internal-use

software that meet the capitalization criteria in accordance with ASC Subtopic

350-40,

Intangibles-Goodwill and Other,

Internal-Use

Software

; and (ii) costs incurred to develop software to be sold/licensed or embedded in its products sold to customers, which are capitalized once technology feasibility is established, which is when a completed detail program design of the product is available in accordance with ASC

950-20,

Costs of Software to be Sold, Leased or Marketed

Government Subsidies

Government subsidies primarily consist of financial subsidies received from provincial and local governments for operating a business in their jurisdictions and compliance with specific policies promoted by the local governments. The government subsidies of operating nature with no further conditions to be met are recorded as a reduction of operating expenses in “Selling, general and administrative” in the consolidated statements of comprehensive income when received. The government subsidies with certain conditions are recorded as “Deferred income” when received and is recognized as income in “Others, net” or as a reduction of specific operating costs and expenses when the conditions are met for which the grants are intended to compensate. If the

government subsidies are related to an asset, it is recognized as a deduction of the carrying amount of the asset when the conditions are met and then recognized ratably over the expected useful life of the related asset as a reduction to the related amortization or depreciation in the consolidated statements of comprehensive income.

For the years ended December 31, 2021, 2022 and 2023, government subsidies recorded as a reduction of

operating costs and expenses

were RMB520 million, RMB728 million and RMB768 million (US$108 million), respectively.

As of December 31, 2022 and 2023, government subsidies recorded as deferred income were RMB231 million and RMB506 million (US$71 million), respectively.

Income Taxes

The Group recognizes income taxes under the liability method. Deferred income taxes are recognized for differences between the financial reporting and tax bases of assets and liabilities at enacted tax rates in effect for the years in which the differences are expected to reverse. The Group records a valuation allowance against the amount of deferred tax assets that it determines is not

more-likely-than-not

to be realized. The effect on deferred taxes of a change in tax rates is recognized in earnings in the period that includes the enactment date.

Deferred income taxes are recognized on the undistributed earnings of subsidiaries, which are presumed to be transferred to the parent company and are subject to withholding taxes, unless there is sufficient evidence to show that the subsidiary has invested or will invest the undistributed earnings indefinitely or that the earnings will be remitted in a

tax-free

liquidation.

The Group applies the provisions of ASC Topic 740,

Income Taxes

(“ASC 740”), in accounting for uncertainty in income taxes. ASC 740 clarifies the accounting for uncertainty in income taxes by prescribing the recognition threshold a tax position is required to meet before being recognized in the financial statements. The Group has elected to classify interest and penalties related to an uncertain tax position (if and when required) as part of income tax expense in the consolidated statements of comprehensive income. The Group does not expect the amount of unrecognized tax benefits to increase significantly in the next 12 months. In general, the PRC tax authorities have up to five years to conduct examinations of the tax filings of the Company’s PRC subsidiaries. Accordingly, the PRC subsidiaries’ tax years of 2018 – 2023 remain open to examination by the respective tax authorities. The Group may also be subject to the examination of the tax filings in other jurisdictions, which are not material to the consolidated financial statements.

Share-based Compensation

The Group accounts for share-based compensation in accordance with ASC Topic 718,

Compensation-Stock Compensation

(“ASC 718”)

The Group has elected to recognize share-based compensation using the straight-line method for all share-based awards issued with no performance conditions. For awards with performance conditions, compensation cost is recognized on an accelerated basis if it is probable that the performance condition will be achieved.

Forfeitures are estimated based on historical experience and are periodically reviewed. Cancellation of an award accompanied by the concurrent grant of a replacement award is accounted for as a modification of the terms of the cancelled award (“modified awards”). The compensation costs associated with the modified awards are recognized if either the original vesting condition or the new vesting condition is achieved. Total recognized compensation cost for the awards is at least equal to the fair value of the awards at the grant date unless at the

date of the modification the performance or service conditions of the original awards are not expected to be satisfied. The incremental compensation cost is measured as the excess of the fair value of the replacement award over the fair value of the cancelled award at the cancellation date. Therefore, in relation to the modified awards, the Group recognizes share-based compensation over the vesting periods of the replacement award, which comprises, (i) the amortization of the incremental portion of share-based compensation over the remaining vesting term and (ii) any unrecognized compensation cost of the original award, using either the original term or the new term, whichever results in higher expenses for each reporting period.

Earnings Per Share ("EPS")

Earnings Per Share (“EPS”)

The Group computes earnings per Class A and Class B ordinary shares in accordance with ASC Topic 260,

Earnings Per Share

(“ASC 260”), using the two-class method. Under the provisions of ASC 260, basic earnings per share is computed using the weighted average number of ordinary shares outstanding during the period except that it does not include unvested ordinary shares subject to repurchase or cancellation. The Group adjusts for the accretion of the redeemable noncontrolling interests in the calculation of income available to ordinary shareholders of the Company used in the earnings per share calculation.

Diluted earnings per share is computed using the weighted average number of ordinary shares and, if dilutive, potential ordinary shares outstanding during the period. Potentially dilutive securities such as share options, restricted shares and convertible senior notes have been excluded from the computation of diluted net earnings per share if their inclusion is anti-dilutive. Potential ordinary shares consist of the incremental ordinary shares issuable upon the exercise of nonvested share options and restricted shares and contracts that may be settled in the Group’s stock or cash. The dilutive effect of outstanding share options, restricted shares is reflected in diluted earnings per share by application of the treasury stock method. The computation of the diluted earnings per Class A ordinary share assumes the conversion of Class B ordinary shares to Class A ordinary shares, while diluted earnings per Class B ordinary share does not assume the conversion of such shares. The Group adjusts for the securities issued by subsidiaries and equity method investees in the calculation of income available to ordinary shareholders of the Company used in the diluted earnings per share calculation.

The liquidation and dividend rights of the holders of the Company’s Class A and Class B ordinary shares are identical, except with respect to voting rights. As a result, and in accordance with ASC 260, the undistributed earnings for each year are allocated based on the contractual participation rights of the Class A and Class B ordinary shares as if the earnings for the year had been distributed. As the liquidation and dividend rights are identical, the undistributed earnings are allocated on a proportionate basis. Further, as the conversion of Class B ordinary shares is assumed in the computation of the diluted earnings per Class A ordinary share, the undistributed earnings are equal to net income for that computation.

For the purposes of calculating the Group’s basic and diluted earnings per Class A and Class B ordinary shares, the ordinary shares relating to the options that were exercised are assumed to have been outstanding from the date of exercise of such options.

Treasury stock

The Company accounts for treasury stock using the cost method. Under this method, the cost incurred to purchase the shares is recorded in “Treasury stock” on the consolidated balance sheets. At retirement of the treasury stock, the ordinary shares account is charged only for the aggregate par value of the shares. The excess of the acquisition cost of treasury stock over the aggregate par value is charged to retained earnings.

Contingencies

The Group records accruals for certain of its outstanding legal proceedings or claims when it is probable that a liability will be incurred and the amount of loss can be reasonably estimated. The Group evaluates, on a quarterly basis, developments in legal proceedings or claims that could affect the amount of any accrual, as well as any developments that would make a loss contingency both probable and reasonably estimable. The Group discloses the amount of the accrual if it is material.

When a loss contingency is not both probable and estimable, the Group does not record an accrued liability but discloses the nature and the amount of the claim, if material. However, if the loss (or an additional loss in excess of the accrual) is at least reasonably possible, then the Group discloses an estimate of the loss or range of loss, unless it is immaterial or an estimate cannot be made. The assessment of whether a loss is probable or reasonably possible, and whether the loss or a range of loss is estimable, often involves complex judgments about future events. Management is often unable to estimate the loss or a range of loss, particularly where (i) the damages sought are indeterminate, (ii) the proceedings are in the early stages, or (iii) there is a lack of clear or consistent interpretation of laws specific to the industry-specific complaints among different jurisdictions. In such cases, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, including eventual loss, fine, penalty or business impact, if any.

Concentration of Risks

Concentration of credit risk

Financial instruments that are potentially subject the Group to significant concentration of credit risk primarily consist of cash and cash equivalents, restricted cash, debt securities, accounts receivable, contract assets, receivables from online payment agencies, amounts due from related parties, long-term time deposits and

held-to-maturity

investments and long-term restricted cash included in “Other

non-current

assets”. The carrying amounts of these assets represent the Group’s maximum exposure to credit risk. As of December 31, 2023, the Group has RMB230.9 billion (US$32.5 billion) in cash and cash equivalents, restricted cash, debt investments and long-term restricted cash, which is held by financial institutions in mainland China and international financial institutions outside of mainland China. In the event of bankruptcy of one of these financial institutions, the Group may not be able to claim its cash and cash equivalents, restricted cash and debt investments back in full. The Group continues to monitor the financial strength of the financial institutions, 82% and 18% of which are held by financial institutions in mainland China and international financial institutions outside of mainland China, respectively. The Group’s total cash and cash equivalents, restricted cash, and debt investments held at three financial institutions in mainland China representing 17%, 16% and 13% of the Group’s total cash and cash equivalents, restricted cash, and debt investments as of December 31, 2023, respectively.

PRC state-owned banks, such as Bank of China, are subject to a series of risk control regulatory standards, and PRC bank regulatory authorities are empowered to take over the operation and management when any of those banks faces a material credit crisis. The Group does not foresee substantial credit risk with respect to cash and cash equivalents, restricted cash and short-term investments held at the PRC state-owned banks. In May 2015, a new Deposit Insurance System (“DIS”) managed by the People’s Bank of China (“PBOC”) was implemented by the Chinese government. Deposits in the licensed banks in mainland China are protected by DIS, up to a limit of RMB0.5

million

. Hong Kong has an official Deposit Protection Scheme (“DPS”). Deposits in the licensed banks in Hong Kong are protected by DPS, up to a limit of HK$

0.5

million

. In the event of bankruptcy of one of the financial institutions in which the Group has deposits or investments, it may be unlikely to claim its deposits or investments back in full. The Group selected reputable international financial institutions with high rating rates to place its foreign currencies. The Group regularly monitors the rating of the international financial institutions to avoid any potential defaults. There has been no recent history of default in relation to these financial institutions.

Accounts receivable, contract assets and receivables from online payment agencies are typically unsecured and derived from revenue earned from customers and agencies in the PRC, which are exposed to credit risk. The risk is mitigated by credit evaluations the Group performs on its customers and its ongoing monitoring process of outstanding balances. The Group maintains an allowance for credit losses and actual losses have generally been within management’s expectations. As of December 31, 2023, the Group had no single customer with a balance exceeding 10% of the total accounts receivable, contract assets, and receivables from online payment agencies.

No customer generated greater than 10% of total revenues during the years presented.

Amounts due from related parties are typically unsecured. In evaluating the collectability of the amounts due from related parties, the Group considers many factors, including the related parties’ repayment history and their credit-worthiness. The Group maintains reserves for estimated credit losses and these losses have generally been within its expectations.

Business and economic risks

The Group participates in the dynamic and competitive high technology industry and believes that changes in any of the following areas could have a material adverse effect on the Group’s future financial position, results of operations and cash flows: changes in the overall demand for services and products; changes in business offerings; competitive pressures due to existing and new entrants; advances and new trends in new technologies and industry standards; changes in bandwidth suppliers; changes in certain strategic relationships or customer relationships; regulatory considerations; copyright regulations; cybersecurity regulations; brand maintenance and enhancement; risks associated with the Group’s ability to anticipate user preferences and provide high-quality content in a cost-effective manner; risks associated with the Group’s ability to attract and retain employees necessary to support its growth and risks related to health epidemics, severe weather conditions and other outbreaks.

The Group’s operations could be adversely affected by significant political, economic and social uncertainties and epidemic in mainland China.

Currency convertibility risk

Substantially all of the Group’s businesses are transacted in RMB, which is not freely convertible into foreign currencies. All foreign exchange transactions take place either through Bank of China or other banks authorized to buy and sell foreign currencies at the exchange rates quoted by the People’s Bank of China. Foreign exchange transactions, including foreign currency payments, require the approval of the People’s Bank of China and/or regulatory institutions.

Foreign currency exchange rate risk

The functional currency and the reporting currency of the Group are the U.S. dollars and the RMB, respectively. The Group’s exposure to foreign currency exchange rate risk primarily relates to cash and cash equivalents, restricted cash, short-term investments, long-term investments, long-term time deposits and

held-to-maturity

securities, accounts and notes payable and convertible senior notes denominated in the U.S. dollars. The appreciation of the U.S. dollars against the RMB was approximately 2.94% in 2023. Most of the revenues and costs of the Group are denominated in RMB, while a portion of cash and cash equivalents, restricted cash, short-term investments, long-term investments, long-term time deposits and

held-to-maturity

securities, notes payable and convertible senior notes are denominated in the U.S. dollars. It is difficult to predict how market forces or

PRC or U.S. government policy may impact the exchange rate between the Renminbi and the U.S. dollar in the future. Any significant fluctuation of the valuation of RMB may materially affect the Group’s cash flows, revenues, earnings and financial position, and the value of, and any dividends payable on, the ADS in U.S. dollars.

Derivative Instruments

ASC Topic 815,

Derivatives and Hedging

(“ASC 815”), requires all contracts which meet the definition of a derivative to be recognized on the balance sheet as either assets or liabilities and recorded at fair value. Changes in the fair value of derivative financial instruments are either recognized periodically in earnings or in other comprehensive (loss) income depending on the use of the derivative and whether it qualifies for hedge accounting. Changes in fair values of derivatives not qualified as hedges are reported in earnings.

Recent Accounting Pronouncements

In March 2020, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”)

2020-04,

Reference Rate Reform (Topic 848): Facilitation of the Effects of Reference Rate Reform on Financial Reporting

and issued subsequent amendments within ASU

2021-01

and ASU

2022-06

(collectively, including ASU

2020-04,

“ASC 848”) in January 2021 and December 2022 respectively. ASC 848 provides optional expedients and exceptions for applying U.S. GAAP on contract modifications and hedge accounting to contracts, hedging relationships, and other transactions that reference LIBOR or another reference rate expected to be discontinued because of reference rate reform, if certain criteria are met. The Group has elected the optional expedients for certain existing interest rate swaps that are designated as cash flow hedges, which did not have a material impact on the financial position, results of operations and cash flows. The Group has evaluated the effects, if any, of the potential election of the other optional expedients and exceptions provided in this guidance on the financial position, results of operations and cash flows, which were insignificant.

In October 2021, the FASB issued ASU

2021-08,

Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers

, which provides guidance on the acquirer’s accounting for acquired revenue contracts with customers in a business combination. The amendments require an acquirer to recognize and measure contract assets and contract liabilities acquired in a business combination at the acquisition date in accordance with ASC 606 as if it had originated the contracts. This guidance also provides certain practical expedients for acquirers when recognizing and measuring acquired contract assets and contract liabilities from revenue contracts in a business combination. The new guidance is required to be applied prospectively to business combinations occurring on or after the date of adoption. This guidance is effective for the Group for fiscal years beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption is permitted. The adoption of this guidance did not have a material impact on its financial position, results of operations and cash flows.

In June 2022, the FASB issued ASU

2022-03,

Fair Value Measurement (Topic 820): Fair Value Measurement of Equity Securities Subject to Contractual Sale Restrictions

, which clarifies that a contractual restriction on the sale of an equity security is not considered part of the unit of account of the equity security and, therefore, is not considered in measuring fair value. The amendments also clarify that an entity cannot, as a separate unit of account, recognize and measure a contractual sale restriction. This guidance also requires certain disclosures for equity securities subject to contractual sale restrictions. The new guidance is required to be applied prospectively with any adjustments from the adoption of the amendments recognized in earnings and disclosed on the date of adoption. This guidance is effective for the Group for fiscal years beginning after December 15, 2023, and interim periods within those fiscal years. Early adoption is permitted. Effective January 1, 2023, the Group early adopted ASU

2022-03 on a prospective basis. The adoption of this guidance did not have a material impact on its financial position, results of operations and cash flows.

In November 2023, the FASB issued ASU 2023-07,

Segment Reporting: Improvements to Reportable Segment

Disclosures

(“ASU 2023-07”), which focuses on improving reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses. A public entity shall disclose for each reportable segment the significant expense categories and amounts that are regularly provided to the CODM and included in reported segment profit or loss. ASU 2023-07 also requires public entities to provide in interim periods all disclosures about a reportable segment’s profit or loss and assets that are currently required annually. Entities are permitted to disclose more than one measure of a segment’s profit or loss if such measures are used by the CODM to allocate resources and assess performance, as long as at least one of those measures is determined in a way that is most consistent with the measurement principles used to measure the corresponding amounts in the consolidated financial statements. ASU 2023-07 is applied retrospectively to all periods presented in financial statements, unless it is impracticable. This update will be effective for the Group’s fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. Early adoption is permitted. The Group is currently in the process of evaluating the disclosure impact of adopting ASU 2023-07.

Equity method investments

The carrying amount of the Group’s equity method investments were RMB25.9 billion and RMB20.8 billion (US$2.9

billion) as of December 31, 2022 and 2023, respectively. For the years ended December 31, 2021, 2022 and 2023, the impairment recognized for equity method investments were RMB

57 million, RMB569 million and RMB62 million (US$9 million), respectively.

For the year ended December 31, 2023, the Group recognized share of losses from equity method investments of RMB

3.8

billion (US$535

million). One of the equity method investees modified certain terms of its preferred shares issued and the Group recognized

RMB3.0

billion losses from this investee mainly as a result of the modification.

Equity Investment in Trip.com International, Ltd. (“Trip”) (formally known as Ctrip)

As of December 31, 2022, the Group held approximately 12% of Trip’s outstanding shares. The Group was considered to have significant influence over Trip and accounts for such investment as an equity method investment in accordance with ASC 323.

During the year ended December 31, 2023, the Group disposed an aggregate of 10

million American Depositary Shares of Trip and recognized disposal gains in aggregate of

RMB1.4 billion.

After the partial disposal of the investment in Trip, the Group held approximately 9% equity interest in Trip, and the Group can actively participate in the operating and financing policies of Trip through its one seat on Trip’s board of directors with a total of eight members. Accordingly, the Group continues to have significant influence over Trip and accounts for its remaining investment as an equity method investment in accordance with ASC 323. As of December 31, 2023, the Group’s investments in Trip had a fair value of RMB15.1 billion (US$2.1 billion), based on the closing share price.

Equity Investment in Jidu Auto Inc. (“Jidu”)

In January 2021, the Group entered into an agreement with Zhejiang Geely Holding Group (“Geely”) to established Jidu to produce intelligent electric vehicles. In 2022, the Group purchased the ordinary shares with amount of US$371 million including common stock of US$171 million and

in-substance

common stock of US$200 million, and preferred shares with amount of US$193 million. In 2023, the Group purchased the Series C Warrant of Jidu with amount of RMB650 million giving rights to acquire 14,443,320 Series C Preferred Shares. After the exercise of such warrants, the Group will hold an equity interest of 51.14%.

However, considering the substantive participating rights held by Geely, the Group accounts for its investment of the ordinary shares as an equity method investment in accordance with ASC 323. Furthermore, the Group accounts for its investment of the preferred shares and Series C Warrant as an equity investment without a readily determinable fair value in accordance with ASC 321.

Equity Investment in Du Xiaoman

After finishing a series of legal restructuring and recapitalization of the financial services business (“Du Xiaoman”), the Group retained 41% of Du Xiaoman’s shares on a fully diluted basis, and accounted for it as an equity method investment in accordance with ASC 323, as the Group retained significant influence over Du Xiaoman.

As of December 31, 2022 and 2023, in addition to the aforementioned equity method investments, the Group held other equity method investments through its subsidiaries or VIEs and over which the Group had significant influence.

For the year ended December 31, 2023, equity method investments held by the Group in aggregate have met the significance criteria as defined under

Rule 4-08(g) of

Regulation S-X.

Investment Commitments

The Group’s investment commitments primarily relate to capital contribution obligations under certain arrangements which do not have specified contractual maturity dates. The total investment commitments contracted but not yet reflected in the consolidated financial statements amounted to RMB1.4 billion (US$197 million).

Guarantees

The Group accounts for guarantees in accordance with ASC Topic 460,

Guarantees

(“ASC 460”)

Accordingly, the Group evaluates its guarantees if any to determine whether (a) the guarantee is specifically excluded from the scope of ASC 460, (b) the guarantee is subject to ASC 460 disclosure requirements only, but not subject to the initial recognition and measurement provisions, or (c) the guarantee is required to be recorded in the financial statements at fair value.

The corporate

by-laws

require that the Company indemnify its officers and directors, as well as those who act as directors and officers of other entities at the Company’s request, against expenses, judgments, fines, settlements

and other amounts actually and reasonably incurred in connection with any proceedings arising out of their services to the Company. In addition, the Company entered into separate indemnification agreements with each director and each executive officer of the Company that provide for indemnification of these directors and officers under similar circumstances and under additional circumstances. The indemnification obligations are more fully described in the

by-laws

and the indemnification agreements. The Company purchases standard directors and officers insurance to cover claims or a portion of the claims made against its directors and officers. Since a maximum obligation is not explicitly stated in the Company’s

by-laws

or in the indemnification agreements and will depend on the facts and circumstances that arise out of any future claims, the overall maximum amount of the obligations cannot be reasonably estimated.

Historically, the Group was not required to make payments related to these obligations, and the fair value for these obligations was immaterial on the consolidated balance sheets as of December 31, 2023.

Litigation

The Group was involved in certain cases pending in various PRC, U.S. and Brazil courts and arbitration as of December 31, 2023. These cases include copyright infringement cases, unfair competition cases, and defamation cases, among others. Adverse results in these lawsuits may include awards of damages and may also result in, or even compel, a change in the Group’s business practices, which could result in a loss of revenue or otherwise harm the business of the Group.

Baidu and iQIYI have been named as defendants in several putative federal securities class actions alleging that defendants made material misstatements and omissions regarding certain reported financial and operational results. Starting in April 2020, iQIYI and certain of its current and former officers and directors were named as defendants in several putative securities class actions filed in federal court, which were purportedly brought on behalf of a class of persons who allegedly suffered damages as a result of alleged misstatements and omissions in iQIYI’s public disclosure documents. In light of the common questions of law and fact at issue in this case and a related action against Baidu, the Court terminated the motion to dismiss without prejudice, and ordered a

motion-to-dismiss

briefing for the two cases under a new coordinated briefing schedule. The coordinated motion-to-dismiss briefing was completed in March 2023. On February 26, 2024, following oral argument on the motions to dismiss, the Court held Defendants’ motions in abeyance, granted Plaintiffs leave to file amended consolidated complaints, and ordered the supplemental briefing on the amended consolidated complaints to be completed by April 22, 2024. Both of those cases remain in preliminary stage, the likelihood of any unfavorable outcome or the amount or range of any potential loss cannot be reasonably estimated at the issuance date of the consolidated financial statements. As a result, as of December 31, 2023, the Group did not record any liabilities for the loss contingencies pertaining to the cases described above.

For many proceedings, the Group is currently unable to estimate the reasonably possible loss or a range of reasonably possible losses as the proceedings are in the early stages, and/or there is a lack of clear or consistent interpretation of laws specific to the industry-specific complaints among different jurisdictions. As a result, there is considerable uncertainty regarding the timing or ultimate resolution of such matters, which includes eventual loss, fine, penalty or business impact, if any, and therefore, an estimate for the reasonably possible loss or a range of reasonably possible losses cannot be made. However, the Group believes that such matters, individually and in the aggregate, when finally resolved, are not reasonably likely to have a material adverse effect on the Group’s consolidated results of operations, financial position and cash flows. With respect to the limited number of proceedings for which the Group was able to estimate the reasonably possible losses or the range of reasonably possible losses, such loss estimates were insignificant.

Fair Value Measurements

Fair Value Disclosures [Abstract]

Fair Value Measurements

26.	FAIR VALUE MEASUREMENTS

ASC 820 establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:


Level 1	–	Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets.
Level 2	–	Include observable inputs other than quoted prices included in Level 1, such as quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets and liabilities in markets that are not active, or other inputs that are observable or can be corroborated by observable market data.
Level 3	–	Unobservable inputs which are supported by little or no market activity.

ASC 820 describes three main approaches to measuring the fair value of assets and liabilities: (1) market approach; (2) income approach and (3) cost approach. The market approach uses prices and other relevant information generated from market transactions involving identical or comparable assets or liabilities. The income approach uses valuation techniques to convert future amounts to a single present value amount. The measurement is based on the value indicated by current market expectations about those future amounts. The cost approach is based on the amount that would currently be required to replace an asset.

Assets and Liabilities Measured or Disclosed at Fair Value on a recurring basis

In accordance with ASC 820, the Group measures equity investments with readily determinable fair value, investments accounted for at fair value,

available-for-sale

debt investments and derivatives instruments at fair value on a recurring basis. The fair values of time deposits are determined based on the prevailing interest rates in the market. The fair values of the Group’s

held-to-maturity

debt investments as disclosed are determined based on the discounted cash flow model using the discount curve of market interest rates. The fair value of the Group’s short-term

available-for-sale

debt investments are measured using the income approach, based on quoted market interest rates of a similar instrument and other significant inputs derived from or corroborated by observable market data. The fair values of the Group’s equity investments in equity securities of publicly listed companies are measured using quoted market prices. The fair value of derivative instruments of interest rate swaps are based on broker quotes. The fair value of financial liability is estimated based on the quoted market price of a similar asset to the underlying assets. Investments accounted for at fair value are equity investments in listed and unlisted companies held by consolidated investment companies. These investments in unlisted companies and long-term

available-for-sale

debt investments do not have readily determinable market value, which were categorized as Level 3 in the fair value hierarchy. The Group uses a market approach based on the Group’s best estimate, which is determined by using information including but not limited to the pricing of recent rounds of financing of the investees, liquidity factors and multiples of a selection of comparable companies.

The fair values of the Group’s notes payable are extracted directly from their quoted market prices. The fair values of the convertible senior notes are classified as Level 2 or Level 3 in the fair value hierarchy. The Group carries the convertible senior notes at face value less unamortized debt discount and issuance costs on its consolidated balance sheets and presents the fair value for disclosure purposes only. For further information on the convertible senior notes, see Note 15.

Assets measured at fair value on a

non-recurring

basis

The Group measures certain

non-financial

assets on a nonrecurring basis.

For equity securities accounted for under the measurement alternative, when there are observable price changes in orderly transactions for identical or similar investments of the same issuer, the investments are

re-measured

to fair value (Note 4). The

non-recurring

fair value measurements to the carrying amount of an investment usually requires management to estimate a price adjustment for the different rights and obligations between a similar instrument of the same issuer with an observable price change in an orderly transaction and the investment held by the Group. These

non-recurring

fair value measurements were measured as of the observable transaction dates. The valuation methodologies involved require management to use the observable transaction price at the transaction date and other unobservable inputs (level 3) such as expected volatility and probability of exit events as it relates to liquidation and redemption preferences. When there is impairment of equity securities accounted for under the measurement alternative and equity method investments, the

non-recurring

fair value measurements are measured at the date of impairment. The fair values of the Group’s equity method investments in publicly listed companies are measured using quoted market prices. Estimating the fair value of investees without observable market prices is highly judgmental due to the subjectivity of the unobservable inputs (level 3) used in the valuation methodologies used to determine fair value. The Group uses valuation methodologies, primarily the market approach, which requires management to use unobservable inputs (level 3) such as selection of comparable companies and multiples, expected volatility, discount for lack of marketability and probability of

exit events as it relates to liquidation and redemption preferences, when applicable. These unobservable inputs and resulting fair value estimates may be affected by unexpected changes in future market or economic conditions.

Other

non-financial

assets, intangible assets, licensed copyrights and produced content, would be measured at fair value whenever events or changes in circumstances indicate the carrying value of an asset may not be recoverable. The fair values of

non-financial

long-lived assets were measured under the income approach, based on the Group’s best estimation. Significant inputs used in the income approach primarily included future estimated cash flows and discount rate.

The following table summarizes the Group’s financial assets held as of December 31, 2022 and 2023 for which a

non-recurring

fair value measurement was recorded during the years ended December 31, 2022 and 2023:

Business Combinations

3.	BUSINESS COMBINATIONS

In 2021, the Group completed several business combinations, total purchase consideration in aggregate was RMB326 million, among which RMB357 million was allocated to goodwill.

In January 2023, the Group acquired 100% equity interests of an entity at a cash consideration of RMB130 million, among which RMB114 million was allocated to goodwill.

Goodwill, which is

non-deductible

for tax purposes, is primarily attributable to the synergies expected to be achieved from the acquisitions.

Neither the results of operations since the acquisition dates nor the pro forma results of operations of the acquirees were presented because the effects of these business combinations, both individually and in aggregate, were not significant to the Group’s consolidated results of operations.

The valuations used in the purchase price allocation were determined by the Group with the assistance of independent third-party valuation firm. The valuation reports considered generally accepted valuation methodologies such as the income, market and cost approaches.

The Group entered into definitive agreements with JOYY Inc. (“JOYY”) and certain of its affiliates, to acquire YY Live on November 16, 2020, and subsequently amended the share purchase agreement on February 7, 2021. Pursuant to the share purchase agreement, the closing of this acquisition is subject to certain conditions, including, among others, obtaining necessary regulatory approvals from governmental authorities.

The share purchase agreement is subject to termination by either party if the closing does not occur by the long stop date. As of December 31, 2023, the long stop date, the closing conditions provided for in the share purchase agreement had not been fully satisfied. On January 1, 2024, the Group exercised its contractual right to terminate the share purchase agreement.

In February 2021, the Group made aggregate payments of US$1.9 billion to JOYY, after considering working capital adjustments of US$0.1

billion and deposited an aggregate of US$1.6 billion into several escrow accounts

accordance with the terms set forth in the share purchase agreement. As of December 31, 2023, US

1.9

billion

was recorded as “Other non-current assets” on the consolidated balance sheets and US$

1.6

billion was recorded as “

Restricted cash

” on the consolidated balance sheets.

Hong Kong

Subsidiaries in Hong Kong are subject to Hong Kong Profits Tax rate at 16.5%, and foreign-derived income is exempted from income tax. There are no withholding taxes upon payment of dividends by the subsidiaries incorporated in Hong Kong to its shareholders.

Mainland China

Preferential EIT rates at 15% is available for qualified “High and New Technology Enterprises” (“HNTEs”). The HNTE certificate is effective for a period of three years. Further, preferential EIT rates are available for qualified Software Enterprises whereby entities are entitled to full exemption from EIT for two years beginning from their first profitable calendar year and a 50% reduction for the subsequent three calendar years.

Certain PRC subsidiaries and VIEs, including Baidu Online, Baidu China, Baidu International and Baidu Netcom, etc. are qualified HNTEs and enjoy a reduced tax rate of 15%

As of December 31, 2023, the Group had tax losses of approximately RMB23.7 billion (US$3.3 billion) derived mainly from entities in the PRC and Hong Kong. The tax losses in the PRC can be carried forward for five years to offset future taxable profit, and the period is currently extended to 10 years for entities qualified as HNTE. The tax losses of entities in the PRC will expire from 2024 to 2033, if not utilized. The tax losses in Hong Kong can be carried forward with no expiration date.

As of December 31, 2023, dividend distribution withholding tax for the potential remittance of earnings from the PRC subsidiaries to offshore entities was RMB1.5 billion (US$207 million). The Group believes that the underlying dividends will be distributed in the future for offshore use, such as merger and acquisition activities. The Group did not provide for additional deferred income taxes and foreign withholding taxes on the undistributed earnings of foreign subsidiaries during the years presented on the basis of its current intent to permanently reinvest its foreign subsidiaries’ earnings. As of December 31, 2023, the total amount of undistributed earnings from the PRC subsidiaries and the VIEs for which no withholding tax has been accrued was RMB171.8 billion (US$24.2 billion). Determination of the amount of unrecognized deferred tax liability related to these earnings is not practicable.

As of December 31, 2022 and 2023, the Group has unrecognized tax benefits of RMB670 million and RMB670 million (US$94 million), respectively, primarily related to the tax-deduction of accrued expenses which were presented in “Other non-current liabilities” in the consolidated balance sheets, if ultimately recognized would impact the annual effective tax rate. It is possible that the amount of unrecognized benefits will change in the next 12 months, however, an estimate of the range of the possible change cannot be made at this moment.

Certain leases include rental escalation clauses, renewal options and/or termination options that are factored into the Group’s determination of lease payments when appropriate. As of December 31, 2023, finance leases were insignificant.

As of December 31, 2022 and 2023, the Group’s operating leases had a weighted average remaining lease term of 14.8 years and 13.6 years, respectively. As of December 31, 2022 and 2023, the Group’s operating leases had a weighted average discount rate of 4.30% and 4.07%, respectively.

Shareholders' Equity

21.	SHAREHOLDERS’ EQUITY

The authorized share capital consisted of 69,632,000,000 shares at a par value of US$0.000000625 per share (previously US$0.00005 per share before the Share Subdivision as detailed in Note 1), of which 66,000,000,000 shares were designated as Class A ordinary shares, 2,832,000,000 as Class B ordinary shares, and 800,000,000 shares designated as preferred shares (previously 825,000,000 shares were designated as Class A ordinary shares, 35,400,000 as Class B ordinary shares, and 10,000,000 shares designated as preferred shares before the Share Subdivision as detailed in Note 1). The rights of the holders of Class A and Class B ordinary shares are identical, except with respect to voting and conversion rights. Each share of Class A ordinary shares is entitled to one vote per share and is not convertible into Class B ordinary shares under any circumstances. Each share of Class B ordinary shares is entitled to ten votes per share and is convertible into one Class A ordinary share at any time by the holder thereof. Upon any transfer of Class B ordinary shares by a holder thereof to any person or entity that is not an affiliate of such holder, such Class B ordinary shares would be automatically converted into an equal

number of Class A ordinary shares. The number of Class B ordinary shares transferred to Class A ordinary shares were 12,600,000, 17,200,000 and 17,320,000 during the years ended December 31, 2021, 2022 and 2023, respectively.

On May 13, 2020, the Company announced a share repurchase program (“2020 share repurchase program”) under which the Company proposed to acquire up to an aggregate of US$1.0 billion of its ordinary shares, effective until July 1, 2021 in the open market or through privately negotiated transactions, depending on market conditions and in accordance with applicable rules and regulations. In August 2020, the board of directors approved a change to the 2020 share repurchase program, increasing the repurchase authorization from US$1.0 billion to US$3.0 billion, and in December 2020, the repurchase authorization was further increased from US$3.0 billion to US$4.5

billion, which is effective through December 31, 2022. In February 2023, the board of directors authorized a share repurchase program, under which the Company may repurchase up to US$5.0 billion of its ADSs or shares, effective until December 31, 2025.

The Company repurchased 57,343,528, 17,307,400 and 42,661,000 Class A ordinary shares from the open market with an aggregate purchase price of RMB7.6 billion, RMB1.9 billion and RMB4.8 billion (US$669 million) during the years ended December 31, 2021, 2022 and 2023, respectively, which has been approved by the Company’s board of directors. The repurchased shares were recorded in the treasury stock account.

Treasury stock

The treasury stock account includes 49,408,840 and 41,182,672 ordinary shares repurchased from the open market as of December 31, 2022 and 2023, respectively.

Such treasury stock is reserved for future issuance upon the exercise of the vested share options and the vesting of restricted shares. During the year ended December 31, 2023, 50,887,168 ordinary shares had been reissued to employees and directors upon the exercise of share options and vesting of restricted shares.

Retained Earnings

In accordance with the Regulations on Enterprises with Foreign Investment of China and their articles of association, the Company’s PRC subsidiaries, being foreign invested enterprises established in China, are required to make appropriations to certain statutory reserves, namely a general reserve fund, an enterprise expansion fund, a staff welfare fund and a bonus fund, all of which are appropriated from net profit as reported in their PRC statutory accounts. Each of the Company’s PRC subsidiaries is required to allocate at least 10% of its

after-tax

profits to a general reserve fund until such fund has reached 50% of its respective registered capital. Appropriations to the enterprise expansion fund and staff welfare and bonus funds are at the discretion of the Company’s subsidiaries.

In accordance with the China Company Laws, the Company’s VIEs must make appropriations from their

after-tax

profits as reported in their PRC statutory accounts to

non-distributable

reserve funds, namely a statutory surplus fund, a statutory public welfare fund and a discretionary surplus fund. Each of the Company’s VIEs is required to allocate at least 10% of its

after-tax

profits to the statutory surplus fund until such fund has reached 50% of its respective registered capital. Appropriations to the statutory public welfare fund and the discretionary surplus fund are made at the discretion of the Company’s VIEs.

General reserve and statutory surplus funds are restricted to

set-off

against losses, expansion of production and operation and increasing registered capital of the respective company. Staff welfare and bonus fund and statutory

public welfare funds are restricted to capital expenditures for the collective welfare of employees. The reserves are not allowed to be transferred to the Company in the form of cash dividends, loans or advances, nor are they allowed for distribution except under liquidation.


	As of December 31,
	2022		2023		2023
	RMB		RMB		US$
	(In millions)
PRC statutory reserve funds		1,218		1,567		221
Unreserved retained earnings		147,123		159,673		22,489

Total retained earnings		148,341		161,240		22,710

Under PRC laws and regulations, there are restrictions on the Company’s PRC subsidiaries and VIEs with respect to transferring certain of their net assets to the Company either in the form of dividends, loans, or advances. Amounts of net assets restricted include paid in capital and statutory reserve funds of the Company’s PRC subsidiaries and the net assets of the VIEs in which the Company has no legal ownership, totaling RMB47.3 billion and RMB48.0 billion (US$6.8 billion) as of December 31, 2022 and 2023, respectively.

Furthermore, cash transfers from the Company’s PRC subsidiaries to their parent companies outside of China are subject to PRC government control of currency conversion. Shortages in the availability of foreign currency may restrict the ability of the PRC subsidiaries and variable interest entities and their subsidiaries to remit sufficient foreign currency to pay dividends or other payments to the Company, or otherwise satisfy their foreign currency denominated obligations.

The changes in accumulated other comprehensive income (loss) by component, net of tax, were as follows:

Balance at December 31, 2023, in US$		(303	)		37			140			(126	)

The amounts reclassified out of accumulated other comprehensive income (loss) represent realized foreign currency translation adjustments, which mainly arose from the disposal of the Group’s partial interests in Trip and realized gains (losses) on the sales of

available-for-sale

investments, which were recorded in “Others, net” in the consolidated statements of comprehensive income. The amounts reclassified were determined on the basis of specific identification. Losses on intracompany foreign currency transactions that are of a long-term-investment nature in the amount of RMB537 million, and gains in the amount of RMB2.1 billion, RMB687 million (US$97 million) were included in the foreign currency translation adjustments for the years ended December 31, 2021, 2022 and 2023, respectively.

The following table sets forth the tax benefit (expense) allocated to each component of other comprehensive (loss) income for the years ended December 31, 2021, 2022 and 2023:

Short-term Loans

Short-term loans as of December 31, 2022 and 2023 amounted to RMB5.3 billion and RMB10.3 billion (US$1.4 billion), respectively, which consisted of RMB denominated borrowings made by the Company’s subsidiaries from financial institutions in mainland China and were repayable within one year. The total outstanding balance of iQIYI’s short-term loans as of December 31, 2022 and 2023 amounted to RMB3.3 billion and RMB3.6 billion (US$503 million), respectively. The total outstanding balance of Baidu Core’s short-term loans as of December 31, 2022 and 2023 amounted to RMB2.0 billion and RMB6.7 billion (US$942 million), respectively.

As of December 31, 2022 and 2023, the repayments of primarily all of the iQIYI’s short-term loans are guaranteed by subsidiaries of iQIYI and collateralized by an office building of one of iQIYI’s VIEs with a carrying amount of RMB522 million and RMB509 million (US$72 million) respectively.

As of December 31, 2022 and 2023, the weighted average interest rates for the outstanding borrowings were approximately 3.42% and 2.82%, respectively, and the aggregate amounts of unused lines of credit for short-term loans were RMB2.6 billion and RMB12.8 billion (US$1.8 billion), respectively.

Structured payable arrangements

In 2021, 2022 and 2023, iQIYI entered into structured payable arrangements with banks or other financial institutions (“factoring arrangements”). Under the factoring arrangements, the suppliers’ receivables collection process was accelerated through selling its receivables from iQIYI to the banks or other financial institutions at a discount. For the years ended December 31, 2021, 2022 and 2023, iQIYI was legally obligated to pay the banks or other financial institutions in the amount totaling

RMB1.1 billion, RMB1.5 billion and RMB1.8 billion (US$249 million), respectively, which will mature within one year.

As a result of the factoring arrangements, the payment terms of the iQIYI’s original accounts payables were substantially modified and considered extinguished as the nature of the original liability has changed from accounts payables to loan borrowings from banks or other financial institutions. The proceeds from borrowings from banks or other financial institutions is a financing activity and is reported as “Proceeds from short-term loans” on the consolidated statements of cash flows. As of December 31, 2022 and 2023, the outstanding borrowings from the factoring arrangements were RMB755 million and RMB1.1 billion (US$149 million), respectively, which are repayable within one year and are included in “Short-term loans” on the consolidated balance sheets.

Long-term Loans

In April 2021, the Company entered into a five-year US$3.0 billion term and revolving facilities agreement with a group of 22 arrangers. The facilities consist of a US$1.5 billion five-year bullet maturity term loan and a US$1.5 billion five-year revolving facility. The facility was priced at 85 basis points over LIBOR and is intended for the general corporate purposes. In June 2021, the Company drew down US$1.5 billion term loan and US$500 million revolving loan under the facility commitment. In June 2023, the facilities were modified and priced at 93 basis points over SOFR (secured overnight financing rate). In connection with the drawdowns and the modification, the Company entered into and restructured the two interest rate swap agreements, pursuant to which each of the loans would be settled with a fixed annual interest rate of 1.71%, during the respective term of the loans.

The total outstanding borrowings were RMB13.7 billion and RMB14.2 billion (US$2.0 billion) as of December 31, 2022 and 2023.

The interest rate swap agreements met the definition of derivatives in accordance with ASC 815 and designated as cash flow hedge to hedge the variability of cash flows in the interest payments associated with its variable-rate debt. The derivatives related to the interest rate swap agreements are accounted for at fair value and included in “Other

non-current

assets” on the consolidated balance sheets (Note 26). As long as the derivative remain highly effective, the Company records the changes in fair value of the derivative instrument in other comprehensive (loss) income as described in Note 21. The gross notional amounts of derivatives designated as hedging instruments was US$2.0 billion and US$2.0 billion as of December 31, 2022 and 2023, respectively.

Share-Based Awards Plan

23.	SHARE-BASED AWARDS PLAN

Baidu, Inc.

2008 Share Incentive plan

In December 2008, the Company adopted a share incentive plan (the “2008 Plan”), which provides for the granting of share incentives, including incentive share options (“ISOs”), restricted shares and any other form of award pursuant to the 2008 Plan, to members of the board, employees, consultants and

non-employees

of the Company. The Company reserved 274,302,160 Class A ordinary shares (previously 3,428,777 Class A ordinary shares before the Share Subdivision as detailed in Note 1) for issuance under the 2008 Plan, which expired in the year 2018. The vesting schedule, time and condition to exercise options is determined by the Company’s compensation committee. The term of the options may not exceed

ten years

from the date of the grant, except that five years is the maximum term of an ISO granted to an employee who holds more than 10% of the voting power of the Company’s share capital.

2018 Share Incentive Plan

In July 2018, the Company adopted a share incentive plan (the “2018 Plan”), which provides for the granting of share incentives, including ISOs, restricted shares and any other form of award pursuant to the 2018 Plan, to members of the board, employees, consultants, and

non-employees

of the Company. The 2018 Plan has a

ten-year

term and a maximum number of 275,516,000 Class A ordinary shares (previously 3,443,950 Class A ordinary shares before the Share Subdivision as detailed in Note 1) available for issuance pursuant to all awards under the 2018 Plan.

2023 Share Incentive Plan

In August 2023, the Company adopted a share incentive plan (the “2023 Plan”), which provides for the granting of ISOs, restricted shares, restricted share units; and any other form of awards granted to a participant pursuant to the 2023 plan to members of the board, employees, and consultants of the Company. The 2023 Plan has a maximum number of

281,230,346 Class A ordinary shares available for issuance pursuant to all awards under the 2023 Plan.

Under the 2008 Plan, the 2018 Plan and the 2023 Plan, the exercise price of an option may be amended or adjusted at the discretion of the compensation committee, the determination of which would be final, binding and conclusive. To the extent not prohibited by applicable laws or exchange rules, a downward adjustment of the exercise prices would be effective without the approval of the Company’s shareholders or the approval of the affected grantees. If the Company grants an ISO to an employee who, at the time of that grant, owns shares representing more than 10% of the voting power of all classes of the Company’s share capital, the exercise price cannot be less than 110% of the fair market value of the Company’s ordinary shares on the date of that grant.

Following the Share Subdivision that took effect on March 1, 2021 as detailed in Notes 1, each Class A ordinary share was subdivided into eighty Class A ordinary shares and each ADS represents eight Class A ordinary shares. Prior and subsequent to March 1, 2021, one ordinary share was and will be issuable upon the vesting of one outstanding restricted share or the exercise of one outstanding share option, respectively. Therefore, following the Share Subdivision, each share option and restricted share is subdivided into eighty share options and eighty restricted shares, the weighted average grant date fair value per restricted share and the weighted average exercise price per share option is diluted by eighty times. The number of restricted shares and share options, the weighted average grant date fair value per restricted share and the weighted average exercise price per share option has been retrospectively adjusted for the Share Subdivision in the following tables.

Incentive share options

The following table summarizes the option activity for the year ended December 31, 2023:


	Number of share options			Weighted average exercise price (US$)		Weighted average remaining contractual life (Years)		Aggregate intrinsic value (US$ in millions)
Incentive share options
Outstanding, December 31, 2022		19,669,296			19		5.6		20

Granted		—			—
Exercised		(1,388,560	)		11
Forfeited/Cancelled		(497,616	)		14

Outstanding, December 31, 2023		17,783,120			19		4.4		17

Vested and expected to vest at December 31, 2023		17,149,656			19		4.3		17

Exercisable at December 31, 2023		16,017,392			19		4.0		17

Total intrinsic value of options exercised for the years ended December 31, 2021, 2022 and 2023 was RMB210 million, RMB124 million and RMB64 million (US$9 million), respectively. The total fair value of options vested during the years ended December 31, 2021, 2022 and 2023 was RMB217 million, RMB193 million and RMB85 million (US$12 million), respectively.

Share options are usually subject to vesting schedules ranging from

two

to four years. As of December 31, 2023, RMB50 million (US$7 million) of unrecognized share-based compensation cost related to share options is expected to be recognized over a weighted-average vesting period of 2.1 years. To the extent the actual forfeiture rate is different from the original estimate, actual share-based compensation costs related to these awards may be different from expectation.

The fair value of each option award was estimated on the date of grant using the Black-Scholes-Merton valuation model. The volatility assumption was estimated based on historical volatility of the Company’s share price applying the guidance provided by ASC 718. Assumptions of the expected term were based on the vesting and contractual terms and employee demographics. The risk-free rate for periods within the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant.

The following table presents the assumptions used to estimate the fair values of the share options granted in the years presented:


	For the years ended December 31,
	2021		2022
Risk-free interest rate		0.63~1.23%		1.92~2.96%
Dividend yield		—		—
Expected volatility range		38.12%~39.82%		40.66%~47.03%
Expected life (in years)		5.80~5.86		5.26~5.49

Note: The company didn’t grant share options in 2023.

In addition, the Company recognizes share-based compensation expense net of estimated forfeiture for shares expected to vest over the service period of the award. Estimated forfeiture rates are primarily based on historical experience of employee turnover. To the extent the Company revises this estimate in the future, share-based compensation expense could be materially impacted in the year of revision, as well as in the following years.

The exercise price of options granted during the years ended December 31, 2021 and 2022 equaled the market price of the ordinary shares on the grant date. The weighted-average grant-date fair value of options granted during the years ended December 31, 2021 and 2022 was US$12 and US$8, respectively.

Restricted Shares

Restricted Shares activity for the year ended December 31, 2023 was as follow:


	Number of shares			Weighted average grant date fair value (US$)
Restricted Shares
Unvested, December 31, 2022		126,250,360			17

Granted		35,125,120			17
Vested		(49,878,448	)		17
Forfeited/Cancelled		(15,334,944	)		17

Unvested, December 31, 2023		96,162,088			17

The total fair value of the restricted shares vested during the years ended December 31, 2021, 2022 and 2023 was RMB5.0 billion, RMB6.2 billion and RMB6.1 billion (US$861 million), respectively. The weighted-average grant-date fair value of the Restricted Shares granted during the years ended December 31, 2021, 2022 and 2023 was US$23, US$15 and US$17, respectively.

As of December 31, 2023, there was RMB4.9 billion (US$686 million) of unrecognized share-based compensation cost related to restricted shares, which is expected to be recognized over a weighted-average vesting period of 2.6 years. To the extent the actual forfeiture rate is different from the original estimate, the actual share-based compensation costs related to these awards may be different from expectation. To the extent the Company revises this estimate in the future, share-based compensation expense could be materially impacted in the year of revision, as well as in the following years.

Subsidiaries-iQIYI

2010 Equity Incentive Plan

In October 2010, iQIYI adopted its 2010 Equity Incentive Plan (the “iQIYI 2010 Plan”), which permits the grant of restricted shares, options and share appreciation rights to the employees, directors, officers and consultants to purchase iQIYI’s ordinary shares. The 2010 Plan is valid and effective for an original term of ten years, and further extended to twenty years on September 15, 2020 commencing from its adoption. Except for service conditions, there were no other vesting conditions for all the awards under the 2010 Plan. As of December 31, 2023, the share option pool under the iQIYI 2010 Plan approved by the Board of Directors of iQIYI was 589,729,714 iQIYI’s ordinary shares. All options granted vest over a four-year period.

2021 Equity Incentive Plan

On December 2, 2021, iQIYI adopted its 2021 Equity Incentive Plan (the “iQIYI 2021 Plan”), which permits the grant of restricted shares units and options to the directors, employees, consultants and other individuals of iQIYI. Under the 2021 Plan, the maximum aggregate number of ordinary shares which may be issued pursuant to all awards shall initially be 364,000,000 iQIYI’s ordinary shares, provided that if restricted share units or options with US$0 exercise price are granted, each restricted share unit and option with US$0 exercise price (that entitles the holder to one ordinary share) granted shall reduce the number of ordinary shares under the 2021 Plan available for future grants by 1.3 ordinary shares. The 2021 Plan is valid and effective for a term of

ten

years commencing from its adoption. Except for service conditions, there were no other vesting conditions for all the awards under the 2021 Plan. Any unvested portion of the restricted shares units and options will be forfeited upon the termination of the grantee’s service for any reason. In the event the grantee’s service is terminated for cause other than death or permanent disability, the vested portion of the options will be expired upon 90 days following such termination. In 2023, iQIYI has granted options under the 2021 Plan to its employees and directors. All options vest over a four-year period.

The following table sets forth the summary of employee option activity for the year ended December 31, 2023:
