Credit Loss [Abstract]

ALLOWANCE FOR CREDIT LOSSES

ALLOWANCE FOR CREDIT LOSSES

We adopted ASU 2016-13, Financial Instruments (Topic 326), as of January 1, 2020. Prior period information was not restated and continues to be presented under guidance effective for those periods. This ASU changes how entities measure credit losses for certain financial assets including accounts receivable by replacing the historical “incurred loss” approach with an “expected loss” model. We have updated our significant accounting policy for allowance for credit losses as described in Note 1, Summary of Significant Accounting Policies.

Our allowance for credit losses is computed using a number of factors including our past credit loss experience, the aging of amounts due from our customers, and our customers' credit ratings, in addition to other customer specific factors. We have also assessed the current macroeconomic environment, including the impact of the COVID-19 pandemic, to determine our ending allowance for credit losses for both accounts receivable and contract assets. The allowance for credit losses on contract assets was not significant.

A rollforward of our allowance for credit losses on our accounts receivable balance is presented below for the twelve months ended December 31, 2020:

Balance, December 31, 2019	$	32,838
Provision	16,130
Write-offs	(10,855)
Balance, December 31, 2020	$	38,113

Recoveries of amounts previously written off were not significant for the twelve months ended December 31, 2020.
