Securities lending transactions, initial collateral percentage value

  
We participate in securities lending programs whereby marketable securities in our investment portfolio are transferred to independent brokers or dealers in exchange for cash and securities collateral. We recognize the collateral as an asset, which is reported under the caption “Other current assets” in our consolidated balance sheets, and we record a corresponding liability for the obligation to return the collateral to the borrower, which is reported under the caption “Other current liabilities” in our consolidated balance sheets. The securities on loan are reported in the applicable investment category on our consolidated balance sheets. Unrealized gains or losses on securities lending collateral are included in accumulated other comprehensive loss as a separate component of shareholders’ equity. The market value of loaned securities and that of the collateral pledged can fluctuate in non-synchronized fashions. To the extent the loaned securities’ value appreciates faster or depreciates slower than the value of the collateral pledged, we are exposed to the risk of the shortfall. As a primary mitigating mechanism, the loaned securities and collateral pledged are marked to market on a daily basis and the shortfall, if any, is collected accordingly. Secondarily, the collateral level is set at 102% of the value of the loaned securities, which provides a cushion before any shortfall arises. The investment of the cash collateral is subject to market risk, which is managed by limiting the investments to higher quality and shorter duration instruments.Receivables: Receivables are reported net of amounts for expected credit losses. The allowance for doubtful accounts is based on historical collection trends, future forecasts and our judgment regarding the ability to collect specific accounts.Premium receivables include the uncollected amounts from insured groups, individuals and government programs. Premium receivables are reported net of an allowance for doubtful accounts of $140 and $142 at March 31, 2022 and December 31, 2021, respectively. Self-funded receivables include administrative fees, claims and other amounts due from self-funded customers. Self-funded receivables are reported net of an allowance for doubtful accounts of $53 and $50 at March 31, 2022 and December 31, 2021, respectively. Other receivables include pharmacy rebates, provider advances, claims recoveries, reinsurance receivables, proceeds due from brokers on investment trades, accrued investment income, and other miscellaneous amounts due to us. These receivables are reported net of an allowance for doubtful accounts of $698 and $648 at March 31, 2022 and December 31, 2021, respectively.Revenue Recognition: For our non-risk-based contracts, we had no material contract assets, contract liabilities or deferred contract costs recorded on our consolidated balance sheet at March 31, 2022. For the three months ended March 31, 2022 and 2021, revenue recognized from performance obligations related to prior periods, such as due to changes in transaction price, was not material. For contracts that have an original expected duration of greater than one year, revenue expected to be recognized in future periods related to unfulfilled contractual performance obligations and contracts with variable consideration related to undelivered performance obligations is not material.Recently Adopted Accounting Guidance: In January 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update No. 2021-01, Reference Rate Reform (Topic 848) (“ASU 2021-01”). The amendments in ASU 2021-01 provide optional expedients and exceptions for applying GAAP to contract modifications and hedging relationships, subject to meeting certain criteria, that reference the London Interbank Offered Rate (“LIBOR”) or another reference rate expected to be discontinued because of the reference rate reform. The provisions must be applied at a Topic, Subtopic, or Industry Subtopic level for all transactions other than derivatives, which may be applied at a hedging relationship level. We adopted ASU 2021-01 on January 7, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows.In October 2020, the FASB issued Accounting Standards Update No. 2020-08, Codification Improvements to Subtopic 310-20, Receivables—Nonrefundable Fees and Other Costs (“ASU 2020-08”).

ASU 2020-08 became effective for interim and annual reporting periods beginning after December 15, 2020. The amendments were to be applied on a prospective basis as of the beginning of the period of adoption for existing or newly purchased callable debt securities. We adopted ASU 2020-08 on January 1, 2021, and the adoption did not have an impact on our consolidated financial position, results of operations or cash flows.In August 2020, the FASB issued Accounting Standards Update No. 2020-06, Debt—Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging—Contracts in Entity’s Own Equity (Subtopic 815-40): Accounting -9-
