Contract Balances

Timing of revenue recognition may differ from the timing of invoicing to customers. Accounts receivable represents amounts invoiced and revenue recognized prior to invoicing when we have satisfied our performance obligation and have the unconditional right to payment. The allowance for doubtful accounts and authorized credits is estimated based upon our assessment of various factors including historical experience, the age of the accounts receivable balances, current economic conditions reasonable and supportable forecasts, and other factors that may affect our customers’ ability to pay. The allowance for doubtful accounts and authorized credits was $115 million and $136 million as of June 30, 2021 and December 31, 2020, respectively. As of June 30, 2021, we reported allowances for doubtful accounts of $80 million reflecting a decrease of $17 million, net of write-offs of $65 million for the six months ended June 30, 2021.

Deferred revenue consists of fees received related to unsatisfied performance obligations at the end of the period. Due to the generally short-term duration of contracts, the majority of the performance obligations are satisfied in the following reporting period. The amount of revenue recognized for the six month period ended June 30, 2021 that was included in the deferred revenue balance at the beginning of the period was $46 million. The amount of revenue recognized for the six month period ended June 30, 2020 that was included in the deferred revenue balance at the beginning of the period was $64 million.
