Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2018 . The condensed consolidated balance sheet as of December 31, 2018 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. The condensed consolidated financial statements include the accounts of Facebook, Inc., its wholly owned subsidiaries, and any variable interest entities for which we are deemed to be the primary beneficiary. All intercompany balances and transactions have been eliminated. The accompanying condensed consolidated financial statements reflect all normal recurring adjustments that are necessary to present fairly the results for the interim periods presented. Interim results are not necessarily indicative of the results for the full year ending December 31, 2019 . Use of Estimates Conformity with GAAP requires the use of estimates and judgments that affect the reported amounts in the consolidated financial statements and accompanying notes. These estimates form the basis for judgments we make about the carrying values of our assets and liabilities, which are not readily apparent from other sources. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. GAAP requires us to make estimates and judgments in several areas, including, but not limited to, those related to income taxes, loss contingencies, fair value of acquired intangible assets and goodwill, collectability of accounts receivable, fair value of financial instruments, leases, useful lives of intangible assets and property and equipment, and revenue recognition. These estimates are based on management's knowledge about current events and expectations about actions we may undertake in the future. Actual results could differ materially from those estimates. Recently Adopted Accounting Pronouncements On January 1, 2019, we adopted Accounting Standards Update No. 2016-02, Leases (Topic 842) (ASU 2016-02), as amended, which supersedes the lease accounting guidance under Topic 840, and generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use (ROU) assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. We adopted the new guidance using the modified retrospective transition approach by applying the new standard to all leases existing at the date of initial application and not restating comparative periods. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while our accounting for finance leases remained substantially unchanged. For information regarding the impact of Topic 842 adoption, see Significant Accounting Policies - Leases and Note 7— Leases. Significant Accounting Policies - Leases On January 1, 2019, we adopted Topic 842 using the modified retrospective transition approach by applying the new standard to all leases existing at the date of initial application. Results and disclosure requirements for reporting periods beginning after January 1, 2019 are presented under Topic 842, while prior period amounts have not been adjusted and continue to be reported in accordance with our historical accounting under Topic 840. We elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classification, our assessment on whether a contract was or contains a lease, and our initial direct costs for any leases that existed prior to January 1, 2019. We also elected to combine our lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of income on a straight-line basis over the lease term. Additionally, for certain equipment leases, we apply a portfolio approach to effectively account for the operating lease ROU assets and liabilities. Upon adoption, we recognized total ROU assets of $ 6.63 billion , with corresponding liabilities of $ 6.35 billion on the condensed consolidated balance sheets. This included $761 million of pre-existing finance lease ROU assets previously reported in the network equipment within property and equipment, net. The ROU assets include adjustments for prepayments and accrued lease payments. The adoption did not impact our beginning retained earnings, or our prior year condensed consolidated statements of income and statements of cash flows. Under Topic 842, we determine if an arrangement is a lease at inception. ROU assets and liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. For this purpose, we consider only payments that are fixed and determinable at the time of commencement. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Our incremental borrowing rate is a hypothetical rate based on our understanding of what our credit rating would be. The ROU asset also includes any lease payments made prior to commencement and is recorded net of any lease incentives received. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise such options.

Earnings Per Share [Abstract]
Earnings per Share	Earnings per Share We compute earnings per share (EPS) of Class A and Class B common stock using the two-class method required for participating securities. We consider restricted stock awards to be participating securities because holders of such shares have non-forfeitable dividend rights in the event of our declaration of a dividend for common shares. Undistributed earnings allocated to participating securities are subtracted from net income in determining net income attributable to common stockholders. Basic EPS is computed by dividing net income attributable to common stockholders by the weighted-average number of shares of our Class A and Class B common stock outstanding, adjusted for outstanding shares that are subject to repurchase. For the calculation of diluted EPS, net income attributable to common stockholders for basic EPS is adjusted by the effect of dilutive securities, including awards under our equity compensation plans. In 2018, the calculation of diluted EPS also included the effect of inducement awards under separate non-plan restricted stock unit (RSU) award agreements. In addition, the computation of the diluted EPS of Class A common stock assumes the conversion of our Class B common stock to Class A common stock, while the diluted EPS of Class B common stock does not assume the conversion of those shares to Class A common stock. Diluted EPS attributable to common stockholders is computed by dividing the resulting net income attributable to common stockholders by the weighted-average number of fully diluted common shares outstanding. RSUs with anti-dilutive effect were excluded from the EPS calculation and they were not material for the three and six months ended June 30, 2019 and 2018 , respectively. Basic and diluted EPS are the same for each class of common stock because they are entitled to the same liquidation and dividend rights. The numerators and denominators of the basic and diluted EPS computations for our common stock are calculated as follows (in millions, except per share amounts): Three Months Ended June 30, Six Months Ended June 30, 2019 2018 2019 2018 Class A Class B Class A Class B Class A Class B Class A Class B Basic EPS: Numerator Net income $ 2,204 $ 412 $ 4,246 $ 860 $ 4,241 $ 804 $ 8,368 $ 1,725 Less: Net income attributable to participating securities — — — — — — 1 — Net income attributable to common stockholders $ 2,204 $ 412 $ 4,246 $ 860 $ 4,241 $ 804 $ 8,367 $ 1,725 Denominator Weighted average shares outstanding 2,405 450 2,407 488 2,400 455 2,405 495 Basic EPS $ 0.92 $ 0.92 $ 1.76 $ 1.76 $ 1.77 $ 1.77 $ 3.48 $ 3.48 Diluted EPS: Numerator Net income attributable to common stockholders $ 2,204 $ 412 $ 4,246 $ 860 $ 4,241 $ 804 $ 8,367 $ 1,725 Reallocation of net income attributable to participating securities — — — — — — 1 — Reallocation of net income as a result of conversion of Class B to Class A common stock 412 — 860 — 804 — 1,725 — Reallocation of net income to Class B common stock — (2 ) — (4 ) — (3 ) — (9 ) Net income attributable to common stockholders for diluted EPS $ 2,616 $ 410 $ 5,106 $ 856 $ 5,045 $ 801 $ 10,093 $ 1,716 Denominator Number of shares used for basic EPS computation 2,405 450 2,407 488 2,400 455 2,405 495 Conversion of Class B to Class A common stock 450 — 488 — 455 — 495 — Weighted average effect of dilutive RSUs and employee stock options 20 — 35 3 18 1 39 5 Number of shares used for diluted EPS computation 2,875 450 2,930 491 2,873 456 2,939 500 Diluted EPS $ 0.91 $ 0.91 $ 1.74 $ 1.74 $ 1.76 $ 1.76 $ 3.43 $ 3.43

Goodwill and Intangible Assets	Goodwill and Intangible Assets During the six months ended June 30, 2019 , we completed business acquisitions that were not material to our condensed consolidated financial statements, either individually or in the aggregate. Accordingly, pro forma historical results of operations related to these business acquisitions during the six months ended June 30, 2019 have not been presented. We have included the financial results of these business acquisitions in our condensed consolidated financial statements from their respective dates of acquisition.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	te 10. Commitments and Contingencies Guarantee In 2018, we established a multi-currency notional cash pool for certain of our entities with a third-party bank provider. Actual cash balances are not physically converted and are not commingled between participating legal entities. As part of the notional cash pool agreement, the bank extends overdraft credit to our participating entities as needed, provided that the overall notionally pooled balance of all accounts in the pool at the end of each day is at least zero. In the unlikely event of a default by our collective entities participating in the pool, any overdraft balances incurred would be guaranteed by Facebook, Inc. Other contractual commitments We also have $4.57 billion of non-cancelable contractual commitments as of June 30, 2019 , the majority of which is related to network infrastructure and our data center operations. These commitments are primarily due within five years. Legal Matters Beginning on March 20, 2018, multiple putative class actions and derivative actions were filed in state and federal courts in the United States and elsewhere against us and certain of our directors and officers alleging violations of securities laws, breach of fiduciary duties, and other causes of action in connection with our platform and user data practices as well as the misuse of certain data by a developer that shared such data with third parties in violation of our terms and policies, and seeking unspecified damages and injunctive relief. Beginning on July 27, 2018, two putative class actions were filed in federal court in the United States against us and certain of our directors and officers alleging violations of securities laws in connection with the disclosure of our earnings results for the second quarter of 2018 and seeking unspecified damages. These two actions subsequently were transferred and consolidated in the U.S. District Court for the Northern District of California with the putative securities class action described above relating to our platform and user data practices. We believe these lawsuits are without merit, and we are vigorously defending them. In addition, our platform and user data practices, as well as the events surrounding the misuse of certain data by a developer became the subject of U.S. Federal Trade Commission (FTC), SEC, state attorneys general, and other government inquiries in the United States, Europe, and other jurisdictions. In July 2019, we entered into a settlement and modified consent order to resolve the FTC inquiry, and we also entered into a settlement to resolve the SEC inquiry, in each case pending federal court approval of the respective settlement. Among other matters, our settlement with the FTC requires us to pay a penalty of $5.0 billion and to significantly enhance our practices and processes for privacy compliance and oversight. In addition, our settlement with the SEC requires us to pay a penalty of $100 million . Beginning on September 28, 2018, multiple putative class actions were filed in state and federal courts in the United States and elsewhere against us alleging violations of consumer protection laws and other causes of action in connection with a third-party cyber-attack that exploited a vulnerability in Facebook’s code to steal user access tokens and access certain profile information from user accounts on Facebook, and seeking unspecified damages and injunctive relief. We believe these lawsuits are without merit, and we are vigorously defending them. In addition, the events surrounding this cyber-attack became the subject of Irish Data Protection Commission (IDPC) and other government inquiries. In addition, from time to time, we are subject to litigation and other proceedings involving law enforcement and other regulatory agencies, including in particular in Brazil and Europe, in order to ascertain the precise scope of our legal obligations to comply with the requests of those agencies, including our obligation to disclose user information in particular circumstances. A number of such instances have resulted in the assessment of fines and penalties against us. We believe we have multiple legal grounds to satisfy these requests or prevail against associated fines and penalties, and we intend to vigorously defend such fines and penalties. From time to time we also notify the IDPC, our designated European privacy regulator under the General Data Protection Regulation, of certain other personal data breaches and privacy issues, and are subject to inquiries and investigations regarding various aspects of our regulatory compliance. In connection with the aforementioned FTC inquiry, we have recorded a probable loss of $5.0 billion in accrued expenses and other current liabilities on our condensed consolidated balance sheet as of June 30, 2019, $3.0 billion of which was previously recognized in the three months ended March 31, 2019. Although we believe that it is reasonably possible that we may incur a substantial loss in some of the other cases, actions, or inquiries described above, we are currently unable to estimate the amount of such losses or a range of possible losses. We are also party to various other legal proceedings, claims, and regulatory, tax or government inquiries and investigations that arise in the ordinary course of business. With respect to these matters, we evaluate the developments on a regular basis and accrue a liability when we believe a loss is probable and the amount can be reasonably estimated. We believe that the amount or any estimable range of reasonably possible or probable loss will not, either individually or in the aggregate, have a material adverse effect on our business and consolidated financial statements. However, the outcome of these matters is inherently uncertain. Therefore, if one or more of these matters were resolved against us for amounts in excess of management's expectations, our results of operations and financial condition, including in a particular reporting period in which any such outcome becomes probable and estimable, could be materially adversely affected. For information regarding income tax contingencies, see Note 12 — Income Taxes.

Stockholders' Equity

Equity [Abstract]
Stockholders' Equity	Stockholders' Equity Share Repurchase Program Our board of directors has authorized a share repurchase program that commenced in 2017 and does not have an expiration date. In December 2018, our board of directors authorized an additional $9.0 billion of repurchases under this program. During the six months ended June 30, 2019 , we repurchased and subsequently retired approximately 9.3 million shares of our Class A common stock for an aggregate amount of approximately $1.65 billion . As of June 30, 2019 , approximately $7.35 billion remained available and authorized for repurchases. The timing and actual number of shares repurchased under the share repurchase program depend on a variety of factors, including price, general business and market conditions, and other investment opportunities, and shares may be repurchased through open market purchases or privately negotiated transactions, including through the use of trading plans intended to qualify under Rule 10b5-1 under the Securities Exchange Act of 1934, as amended. Share-based Compensation Plans We maintain two share-based employee compensation plans: the 2012 Equity Incentive Plan, which was amended in each of June 2016 and February 2018 (Amended 2012 Plan), and the 2005 Stock Plan (collectively, Stock Plans). Our Amended 2012 Plan serves as the successor to our 2005 Stock Plan and provides for the issuance of incentive and nonstatutory stock options, restricted stock awards, stock appreciation rights, RSUs, performance shares, and stock bonuses to qualified employees, directors and consultants. Outstanding awards under the 2005 Stock Plan continue to be subject to the terms and conditions of the 2005 Stock Plan. Shares that are withheld in connection with the net settlement of RSUs or forfeited under our Stock Plans are added to the reserves of the Amended 2012 Plan. We account for forfeitures as they occur. Effective January 1, 2019, there were 143 million shares of our Class A common stock reserved for future issuance under our Amended 2012 Plan. The number of shares reserved for issuance under our Amended 2012 Plan increases automatically on January 1 of each of the calendar years during the term of the Amended 2012 Plan, which will continue through April 2026 unless terminated earlier by our board of directors or a committee thereof, by a number of shares of Class A common stock equal to the lesser of (i) 2.5% of the total issued and outstanding shares of our Class A common stock as of the immediately preceding December 31st or (ii) a number of shares determined by our board of directors. The following table summarizes the activities for our unvested RSUs for the six months ended June 30, 2019 : Unvested RSUs Number of Shares Weighted Average Grant Date Fair Value (in thousands) Unvested at December 31, 2018 67,298 $ 144.77 Granted 41,695 $ 167.10 Vested (16,744 ) $ 135.50 Forfeited (5,852 ) $ 136.21 Unvested at June 30, 2019 86,397 $ 157.92 The fair value as of the respective vesting dates of RSUs that vested during the three and six months ended June 30, 2019 was $1.58 billion and $2.89 billion , respectively, and $2.17 billion and $4.12 billion during the three and six months ended June 30, 2018 , respectively. As of June 30, 2019 , there was $12.82 billion of unrecognized share-based compensation expense related to RSUs. This unrecognized compensation expense is expected to be recognized over a weighted-average period of approximately three years

Income Taxes

Income Taxes	6 Months Ended

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes Our tax provision for interim periods is determined using an estimated annual effective tax rate, adjusted for discrete items arising in that quarter. In each quarter, we update the estimated annual effective tax rate and make a year-to-date adjustment to the provision. The estimated annual effective tax rate is subject to significant volatility due to several factors, including our ability to accurately predict the proportion of our income (loss) before provision for income taxes in multiple jurisdictions, the effects of acquisitions, and the integration of those acquisitions. Our 2019 effective tax rate differs from the U.S. statutory rate of 21% primarily due to a portion of our income before provision for income taxes being earned in jurisdictions subject to tax rates lower than 21% , the provision for income taxes recorded as a result of the developments in Altera Corp. v. Commissioner discussed below, the $5.0 billion legal accruals recorded in 2019 related to the FTC settlement which is not expected to be tax-deductible, and the recognition of excess tax benefits from share-based compensation. Our gross unrecognized tax benefits were $ 6.84 billion and $4.68 billion on June 30, 2019 and December 31, 2018 , respectively. If the gross unrecognized tax benefits as of June 30, 2019 were realized in a subsequent period, this would result in a tax benefit of $4.07 billion within our provision of income taxes at such time. The amount of interest and penalties accrued as of June 30, 2019 and December 31, 2018 was $549 million and $340 million , respectively. We expect to continue to accrue unrecognized tax benefits for certain recurring tax positions. On July 27, 2015, the United States Tax Court issued a decision (Tax Court Decision) in Altera Corp. v. Commissioner , which concluded that related parties in a cost sharing arrangement are not required to share expenses related to share-based compensation. The Tax Court Decision was appealed by the Commissioner to the Ninth Circuit Court of Appeals (Ninth Circuit). On June 7, 2019, a three-judge panel from the Ninth Circuit issued an opinion ( Altera Ninth Circuit Panel Opinion) that reversed the Tax Court Decision. Based on the Altera Ninth Circuit Panel Opinion, we recorded a cumulative income tax expense of $1.11 billion in the second quarter of 2019. On July 22, 2019, the taxpayer requested a rehearing before the full Ninth Circuit and may subsequently appeal from the Ninth Circuit to the Supreme Court. As a result, the final outcome of the case is uncertain. If the Altera Ninth Circuit Panel Opinion is reversed, we would anticipate recording an income tax benefit at that time. We are subject to taxation in the United States and various other state and foreign jurisdictions. The material jurisdictions in which we are subject to potential examination include the United States and Ireland. We are under examination by the Internal Revenue Service (IRS) for our 2014 through 2016 tax years and by the Ireland tax authorities for our 2012 through 2015 tax years. Our 2017 and subsequent tax years remain open to examination by the IRS. Our 2016 and subsequent tax years remain open to examination in Ireland. In July 2016, we received a Statutory Notice of Deficiency (Notice) from the IRS related to transfer pricing with our foreign subsidiaries in conjunction with the examination of the 2010 tax year. While the Notice applies only to the 2010 tax year, the IRS states that it will also apply its position for tax years subsequent to 2010, which, if the IRS prevails in its position, could result in an additional federal tax liability of an estimated, aggregate amount of up to approximately $5.0 billion in excess of the amounts in our originally filed U.S. return, plus interest and any penalties asserted. We do not agree with the position of the IRS and have filed a petition in the Tax Court challenging the Notice. In March 2018, we received a second Notice from the IRS in conjunction with the examination of our 2011 through 2013 tax years. The IRS applied its position from the 2010 tax year to each of these years and also proposed new adjustments related to other transfer pricing with our foreign subsidiaries and certain tax credits that we claimed. If the IRS prevails in its position for these new adjustments, this could result in an additional federal tax liability of up to approximately $680 million in excess of the amounts in our originally filed U.S. return, plus interest and any penalties asserted. We do not agree with the positions of the IRS in the second Notice and have filed a petition in the Tax Court challenging the second Notice. We have previously accrued an estimated unrecognized tax benefit consistent with the guidance in ASC 740 that is lower than the potential additional federal tax liability from the positions taken by the IRS in the two Notices. In addition, if the IRS prevails in its positions related to transfer pricing with our foreign subsidiaries, the additional tax that we would owe would be partially offset by a reduction in the tax that we owe under the mandatory transition tax on accumulated foreign earnings from the 2017 Tax Cuts and Jobs Act (Tax Act). As of June 30, 2019 , we have not resolved these matters and proceedings continue in the Tax Court. We believe that adequate amounts have been reserved in accordance with ASC 740 for any adjustments to the provision for income taxes or other tax items that may ultimately result from these examinations. The timing of the resolution, settlement, and closure of any audits is highly uncertain, and it is reasonably possible that the balance of gross unrecognized tax benefits could significantly change in the next 12 months. Given the number of years remaining that are subject to examination, we are unable to estimate the full range of possible adjustments to the balance of gross unrecognized tax benefits. If the taxing authorities prevail in the assessment of additional tax due, the assessed tax, interest, and penalties, if any, could have a material adverse impact on our financial position, results of operations, and cash flows.

Summary of Significant Accounting Policies (Policies)	6 Months Ended

Accounting Policies [Abstract]
Basis of Presentation	The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with generally accepted accounting principles in the United States (GAAP) and applicable rules and regulations of the Securities and Exchange Commission (SEC) regarding interim financial reporting. Certain information and note disclosures normally included in the financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. As such, the information included in this quarterly report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2018 . The condensed consolidated balance sheet as of December 31, 2018 included herein was derived from the audited financial statements as of that date, but does not include all disclosures including notes required by GAAP. The condensed consolidated financial statements include the accounts of Facebook, Inc., its wholly owned subsidiaries, and any variable interest entities for which we are deemed to be the primary beneficiary. All intercompany balances and transactions have been eliminated. The accompanying condensed consolidated financial statements reflect all normal recurring adjustments that are necessary to present fairly the results for the interim periods presented. Interim results are not necessarily indicative of the results for the full year ending December 31, 2019 .
Use of Estimates	Conformity with GAAP requires the use of estimates and judgments that affect the reported amounts in the consolidated financial statements and accompanying notes. These estimates form the basis for judgments we make about the carrying values of our assets and liabilities, which are not readily apparent from other sources. We base our estimates and judgments on historical information and on various other assumptions that we believe are reasonable under the circumstances. GAAP requires us to make estimates and judgments in several areas, including, but not limited to, those related to income taxes, loss contingencies, fair value of acquired intangible assets and goodwill, collectability of accounts receivable, fair value of financial instruments, leases, useful lives of intangible assets and property and equipment, and revenue recognition. These estimates are based on management's knowledge about current events and expectations about actions we may undertake in the future. Actual results could differ materially from those estimates.
Recently Adopted Accounting Pronouncements	On January 1, 2019, we adopted Accounting Standards Update No. 2016-02, Leases (Topic 842) (ASU 2016-02), as amended, which supersedes the lease accounting guidance under Topic 840, and generally requires lessees to recognize operating and financing lease liabilities and corresponding right-of-use (ROU) assets on the balance sheet and to provide enhanced disclosures surrounding the amount, timing and uncertainty of cash flows arising from leasing arrangements. We adopted the new guidance using the modified retrospective transition approach by applying the new standard to all leases existing at the date of initial application and not restating comparative periods. The most significant impact was the recognition of ROU assets and lease liabilities for operating leases, while our accounting for finance leases remained substantially unchanged. For information regarding the impact of Topic 842 adoption, see Significant Accounting Policies - Leases
Earnings Per Share	We compute earnings per share (EPS) of Class A and Class B common stock using the two-class method required for participating securities. We consider restricted stock awards to be participating securities because holders of such shares have non-forfeitable dividend rights in the event of our declaration of a dividend for common shares. Undistributed earnings allocated to participating securities are subtracted from net income in determining net income attributable to common stockholders. Basic EPS is computed by dividing net income attributable to common stockholders by the weighted-average number of shares of our Class A and Class B common stock outstanding, adjusted for outstanding shares that are subject to repurchase. For the calculation of diluted EPS, net income attributable to common stockholders for basic EPS is adjusted by the effect of dilutive securities, including awards under our equity compensation plans. In 2018, the calculation of diluted EPS also included the effect of inducement awards under separate non-plan restricted stock unit (RSU) award agreements. In addition, the computation of the diluted EPS of Class A common stock assumes the conversion of our Class B common stock to Class A common stock, while the diluted EPS of Class B common stock does not assume the conversion of those shares to Class A common stock. Diluted EPS attributable to common stockholders is computed by dividing the resulting net income attributable to common stockholders by the weighted-average number of fully diluted common shares outstanding.
Leases	On January 1, 2019, we adopted Topic 842 using the modified retrospective transition approach by applying the new standard to all leases existing at the date of initial application. Results and disclosure requirements for reporting periods beginning after January 1, 2019 are presented under Topic 842, while prior period amounts have not been adjusted and continue to be reported in accordance with our historical accounting under Topic 840. We elected the package of practical expedients permitted under the transition guidance, which allowed us to carryforward our historical lease classification, our assessment on whether a contract was or contains a lease, and our initial direct costs for any leases that existed prior to January 1, 2019. We also elected to combine our lease and non-lease components and to keep leases with an initial term of 12 months or less off the balance sheet and recognize the associated lease payments in the consolidated statements of income on a straight-line basis over the lease term. Additionally, for certain equipment leases, we apply a portfolio approach to effectively account for the operating lease ROU assets and liabilities. Upon adoption, we recognized total ROU assets of $ 6.63 billion , with corresponding liabilities of $ 6.35 billion on the condensed consolidated balance sheets. This included $761 million of pre-existing finance lease ROU assets previously reported in the network equipment within property and equipment, net. The ROU assets include adjustments for prepayments and accrued lease payments. The adoption did not impact our beginning retained earnings, or our prior year condensed consolidated statements of income and statements of cash flows. Under Topic 842, we determine if an arrangement is a lease at inception. ROU assets and liabilities are recognized at commencement date based on the present value of remaining lease payments over the lease term. For this purpose, we consider only payments that are fixed and determinable at the time of commencement. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate based on the information available at commencement date in determining the present value of lease payments. Our incremental borrowing rate is a hypothetical rate based on our understanding of what our credit rating would be. The ROU asset also includes any lease payments made prior to commencement and is recorded net of any lease incentives received. Our lease terms may include options to extend or terminate the lease when it is reasonably certain that we will exercise such options.
