Credit Losses on Financial Instruments

Credit Losses on Financial Instruments

In accordance with ASC 326, "Financial Instruments - Credit Losses," we aggregate financial assets with similar risk characteristics to align our expected credit losses with the credit quality or deterioration over the life of such assets. We monitor certain risk characteristics within our aggregated financial assets and revise their composition accordingly, to the extent internal and external risk factors change each reporting period. Financial assets that do not share risk characteristics with other financial assets are evaluated separately. Our financial assets measured at amortized cost primarily consist of accounts receivable.

We use a loss rate method to estimate our allowance for credit losses. Our determination of the current expected credit loss rate begins with our use of historical loss experience as a percentage of accounts receivable. We measure our historical loss period based on the average days to recognize accounts receivable as credit losses. When asset specific characteristics and current conditions change from those in the historical period, due to changes in our credit and collections strategy, certain classes of aged balances, or credit loss and recovery policies, we perform a qualitative and quantitative assessment to adjust our historical loss rate. We use regression analysis to develop an expected loss rate using historical experience and economic data over a forecast period. We measure our forecast period based on the average days to collect payment on billed accounts receivable. To determine our current allowance for credit losses, we combine the historical and expected credit loss rates and apply them to our period end accounts receivable.

In conjunction with our internal reorganization, as referenced in Note 11—Segment Information, we pooled certain assets with similar credit risk characteristics based on the nature of our customers, their industry, policies used to grant credit terms and their historical and expected credit loss patterns. Additionally, we reassessed our historical loss period for the segment portfolio reorganization.

If there is a deterioration of a customer's financial condition or if future default rates in general differ from currently anticipated default rates (including changes caused by COVID-19), we may need to adjust the allowance for credit losses, which would affect earnings in the period that adjustments are made.

The assessment of the correlation between historical observed default rates, current conditions and forecasted economic conditions requires judgment. Alternative interpretations of these factors could have resulted in different conclusions regarding the allowance for credit losses. The amount of credit loss is sensitive to changes in circumstances and forecasted economic conditions. Our historical credit loss experience, current conditions and forecast of economic conditions may also not be representative of the customers' actual default experience in the future.

The following table presents the activity of our allowance for credit losses by accounts receivable portfolio for the six months ended June 30, 2021:

	Business		Mass Markets	Total
	(Dollars in millions)
Beginning balance at January 1, 2021(1)	$	109	82	191
Provision for expected losses	21		32	53
Write-offs charged against the allowance	(35)		(82)	(117)
Recoveries collected	8		17	25
Ending balance at June 30, 2021	$	103	49	152

(1)As described in Note 11—Segment Information, we completed an internal reorganization in January 2021. As a result of this change, allowance for credit losses previously included in the Consumer and Business portfolio of $70 million related to consumer and $12 million related to our small business group, respectively, were reclassified to the Mass Markets allowance for credit losses on January 1, 2021.

For the six months ended June 30, 2021, we decreased our allowance for credit losses for our business and mass markets accounts receivable portfolios primarily due to higher write-off activity in the first half of 2021 with the easing of prior delays due to COVID-19 related restrictions in 2020 and lower receivable balances.
