Contract Asset and Accounts Receivable

Contract Assets and Liabilities

With respect to a small number of contracts for the sale of compounds, the Company has an “enforceable right to payment for performance to date” and as the products do not have an alternative use, the Company recognizes revenue for these contracts over time and records a contract asset using the output method. The output method recognizes revenue on the basis of direct measurements of the value to the customer of the goods or services transferred to date relative to the remaining goods or services promised under the contract.

As of June 30, 2021 and December 31, 2020, the Company's gross accounts receivable was $2.101 billion and $950 million, respectively. The Company's contract assets and contract liabilities as of June 30, 2021 and December 31, 2020 were not material.

Schedule of Bad Debt Reserve

Expected Credit Losses

The Company is exposed to credit losses primarily through its sales of products. To determine the appropriate allowance for expected credit losses, the Company considers certain credit quality indicators, such as aging, collection history, and creditworthiness of debtors. Regional and Global Credit committees review and approve specific customer allowance reserves. The allowance for expected credit losses is primarily based on two primary factors: i) the aging of the different categories of trade receivables, and ii) a specific reserve for accounts identified as uncollectible.

The Company also considers current and future economic conditions in the determination of the allowance. At June 30, 2021, the Company reported $2.059 billion of trade receivables, net of allowances of $42 million. Based on the aging analysis as of June 30, 2021, approximately 90% of our accounts receivable were current based on the payment terms of the invoice. Receivables that are past due by over 365 days account for approximately 1% of our accounts receivable.

The following is a rollforward of the Company's allowances for bad debts for the six months ended June 30, 2021, with the write-offs being under $1 million, which was not material:
