Use of Estimates	Use of Estimates Preparation of condensed consolidated financial statements in conformity with GAAP requires the use of estimates and judgments that affect the reported amounts in the condensed 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 revenue recognition, valuation of non-marketable equity securities, income taxes, loss contingencies, including the ultimate resolution of litigation, regulatory matters, and asserted and unasserted claims, valuation of long-lived assets including goodwill, intangible assets, and property and equipment, and their associated estimated useful lives, valuation of purchase commitments, credit losses of available-for-sale debt securities and accounts receivable, fair value of financial instruments, and fair value of leases. These estimates are based on management's knowledge about current events, interpretation of regulations, and expectations about actions we may undertake in the future. Actual results could differ materially from those estimates.

Earnings Per Share	We compute earnings per share (EPS) of Class A and Class B common stock using the two-class method. As the liquidation and dividend rights for both Class A and Class B common stock are identical, the undistributed earnings are allocated on a proportionate basis to the weighted-average number of common shares outstanding for the period. Basic EPS is computed by dividing net income by the weighted-average number of shares of our Class A and Class B common stock outstanding. For the calculation of diluted EPS, net income for basic EPS is adjusted by the effect of dilutive securities, including awards under our equity compensation plan. 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 is computed by dividing the resulting net income by the weighted-average number of fully diluted common shares outstanding.
Segment Reporting	We report our financial results for our two reportable segments: Family of Apps (FoA) and Reality Labs (RL). FoA includes Facebook, Instagram, Messenger, WhatsApp, and other services. RL includes augmented and virtual reality related consumer hardware, software, and content. Our operating segments are the same as our reportable segments. Revenue and costs and expenses are generally directly attributed to our segments. These costs and expenses include certain product development related operating expenses, costs associated with partnership arrangements, consumer hardware product costs, content costs, and legal-related costs. Indirect costs are allocated to segments based on a reasonable allocation methodology, when such costs are significant to the performance measures of the operating segments. Indirect cost of revenue is allocated to our segments based on usage, such as costs related to the operation of our data centers and technical infrastructure. Indirect operating expenses, such as facilities, information technology, certain shared research and development activities, recruiting, and physical security expenses, are mostly allocated based on headcount.

Use of Estimates

Preparation of condensed consolidated financial statements in conformity with GAAP requires the use of estimates and judgments that affect the reported amounts in the condensed 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 revenue recognition, valuation of non-marketable equity securities, income taxes, loss contingencies, including the ultimate resolution of litigation, regulatory matters, and asserted and unasserted claims, valuation of long-lived assets including goodwill, intangible assets, and property and equipment, and their associated estimated useful lives, valuation of purchase commitments, credit losses of available-for-sale debt securities and accounts receivable, fair value of financial instruments, and fair value of leases. These estimates are based on management's knowledge about current events, interpretation of regulations, and expectations about actions we may undertake in the future. Actual results could differ materially from those estimates.
