Refer to Note 4 "Revenue" concerning the Company's costs in excess of billings.

The Company is exposed to credit losses through sales of products and services. The Company’s expected loss allowance methodology for accounts receivable and costs in excess of billings (collectively "accounts receivable") is developed using historical collection experience, current and future economic and market conditions, and a review of the current status of customers' accounts receivables. Due to the short-term nature of such accounts receivable, the estimated amount of accounts receivable that may not be collected is based on aging of the accounts receivable balances. Additionally, specific allowance amounts are established to record the appropriate provision for customers that no longer share risk characteristics similar with other accounts receivable. The Company’s monitoring activities include timely account reconciliation, dispute resolution, payment confirmation, consideration of customers' financial condition and macroeconomic conditions. Balances are written off when determined to be uncollectible. The Company considered the current and expected future economic and market conditions surrounding the coronavirus ("COVID-19") pandemic and determined that the estimate of credit losses was not significantly impacted as of March 31, 2020.

Estimates are used to determine the allowance. It is based on assessment of anticipated payment and all other historical, current and future information that is reasonably available.

The following table provides a roll-forward of the allowance for credit losses that is deducted from the amortized cost basis of accounts receivable to present the net amount expected to be collected.
