Allowance for Credit Losses

Effective

January 1, 2020,

the Company adopted ASU

Financial Instruments – Credit Losses (ASC

) which is required to be applied by means of a cumulative-effect adjustment to the opening retained earnings balance as of the adoption date. This ASU replaces the incurred loss impairment model with an expected credit loss impairment model for financial instruments, including trade receivables and contract assets. The amendment requires entities to consider forward-looking information to estimate expected credit losses, resulting in earlier recognition of losses for receivables that are current or

not

yet due, which were

not

considered under the previous accounting guidance. There was

impact to the Company’s opening retained earnings or its consolidated balance sheet upon adoption.

The Company is exposed to credit losses primarily through sales of products and services. The Company’s expected loss allowance methodology for accounts receivable is developed using historical collection experience, current and future economic and market conditions and a review of the current status of customers' trade accounts receivables. Due to the short-term nature of such receivables, the estimate of amount of accounts receivable that

may

not

be collected is based on aging of the accounts receivable balances and the financial condition of customers. Additionally, specific allowance amounts are established to record the appropriate provision for customers that have a higher probability of default. 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 novel coronavirus ("COVID-

19"

) pandemic and included specific allowance amounts for any customer determined to have been significantly impacted. 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 for the
