Chapter 4 — Measurement of Expected Credit Losses

4.4 Measurement Methods and Techniques

4.4 Measurement Methods and Techniques

ASC 326-20
30-3 The allowance for credit losses may be determined using various methods. For example, an entity may use discounted cash flow methods, loss-rate methods, roll-rate methods, probability-of-default methods, or methods that utilize an aging schedule. An entity is not required to utilize a discounted cash flow method to estimate expected credit losses. Similarly, an entity is not required to reconcile the estimation technique it uses with a discounted cash flow method.
30-4 If an entity estimates expected credit losses using methods that project future principal and interest cash flows (that is, a discounted cash flow method), the entity shall discount expected cash flows at the financial asset’s effective interest rate. When a discounted cash flow method is applied, the allowance for credit losses shall reflect the difference between the amortized cost basis and the present value of the expected cash flows. If the financial asset’s contractual interest rate varies based on subsequent changes in an independent factor, such as an index or rate, for example, the prime rate, the London Interbank Offered Rate (LIBOR), or the U.S. Treasury bill weekly average, that financial asset’s effective interest rate (used to discount expected cash flows as described in this paragraph) shall be calculated based on the factor as it changes over the life of the financial asset. An entity is not required to project changes in the factor for purposes of estimating expected future cash flows. If the entity projects changes in the factor for the purposes of estimating expected future cash flows, it shall use the same projections in determining the effective interest rate used to discount those cash flows. In addition, if the entity projects changes in the factor for the purposes of estimating expected future cash flows, it shall adjust the effective interest rate used to discount expected cash flows to consider the timing (and changes in the timing) of expected cash flows resulting from expected prepayments in accordance with paragraph 326-20-30-4A. Subtopic 310-20 on receivables — nonrefundable fees and other costs provides guidance on the calculation of interest income for variable rate instruments.

30-4 If an entity estimates expected credit losses using methods that project future principal and interest cash flows (that is, a discounted cash flow method), the entity shall discount expected cash flows at the financial asset’s effective interest rate. When a discounted cash flow method is applied, the allowance for credit losses shall reflect the difference between the amortized cost basis and the present value of the expected cash flows. If a financial asset is modified and is considered to be a continuation of the original asset, an entity shall use the post-modification contractual interest rate to derive the effective interest rate when using a discounted cash flow method. See paragraph 815-25-35-10 for guidance on the treatment of a basis adjustment related to an existing portfolio layer method hedge. If the financial asset’s contractual interest rate varies based on subsequent changes in an independent factor, such as an index or rate, for example, the prime rate, the London Interbank Offered Rate (LIBOR), or the U.S. Treasury bill weekly average, that financial asset’s effective interest rate (used to discount expected cash flows as described in this paragraph) shall be calculated based on the factor as it changes over the life of the financial asset. An entity is not required to project changes in the factor for purposes of estimating expected future cash flows. If the entity projects changes in the factor for the purposes of estimating expected future cash flows, it shall use the same projections in determining the effective interest rate used to discount those cash flows.

Subtopic 310-20 on receivables — nonrefundable fees and other costs provides guidance on the calculation of interest income for variable rate instruments.
30-4A As an accounting policy election for each class of financing receivable or major security type, an entity may adjust the effective interest rate used to discount expected cash flows to consider the timing (and changes in timing) of expected cash flows resulting from expected prepayments. However, if the asset is restructured in a troubled debt restructuring, the effective interest rate used to discount expected cash flows shall not be adjusted because of subsequent changes in expected timing of cash flows.

30-4A As an accounting policy election for each class of financing receivable or major security type, an entity may adjust the effective interest rate used to discount expected cash flows to consider the timing (and changes in timing) of expected cash flows resulting from expected prepayments.
30-5A An entity may make an accounting policy election, at the class of financing receivable or the major security-type level, not to measure an allowance for credit losses for accrued interest receivables if the entity writes off the uncollectible accrued interest receivable balance in a timely manner. This accounting policy election should be considered separately from the accounting policy election in paragraph 326-20-35-8A. An entity may not analogize this guidance to components of amortized cost basis other than accrued interest.

ASC 250-10-20 defines a change in accounting principle as follows:
A change from one generally accepted accounting principle to another generally accepted accounting principle when there are two or more generally accepted accounting principles that apply or when the accounting principle formerly used is no longer generally accepted. A change in the method of applying an accounting principle also is considered a change in accounting principle.

ASC 250-10-20 defines a change in accounting estimate as follows:
A change that has the effect of adjusting the carrying amount of an existing asset or liability or altering the subsequent accounting for existing or future assets or liabilities. A change in accounting estimate is a necessary consequence of the assessment, in conjunction with the periodic presentation of financial statements, of the present status and expected future benefits and obligations associated with assets and liabilities. Changes in accounting estimates result from new information. Examples of items for which estimates are necessary are uncollectible receivables, inventory obsolescence, service lives and salvage values of depreciable assets, and warranty obligations.

ASC 250-10-20 defines a change in accounting estimate effected by a change in accounting principle as follows:
A change in accounting estimate that is inseparable from the effect of a related change in accounting principle. An example of a change in estimate effected by a change in principle is a change in the method of depreciation, amortization, or depletion for long-lived, nonfinancial assets.
ASC 250-10-45-18 highlights that an entity must often use judgment to differentiate between a change in accounting principle and a change in accounting estimate and discusses certain changes that reflect a change in accounting estimate effected by a change in accounting principle.

The EIR is different for PCD assets. ASC 326 states that when determining the EIR “[f]or purchased financial assets with credit deterioration, however, to decouple interest income from credit loss recognition, the premium or discount at acquisition excludes the discount embedded in the purchase price that is attributable to the acquirer’s assessment of credit losses at the date of acquisition.”

After adoption of ASU 2022-02, this requirement would no longer be relevant because the ASU eliminated the concept of a TDR from a creditor’s accounting.

Discussed at the August 29, 2018, FASB meeting.

Although ASU 2022-02 eliminates the TDR guidance in ASC 310-40, the guidance in ASC 310-40-15-20 has been moved to ASC 310-10-50-45. As a result, a creditor would now refer to ASC 310-10-50-45 when determining whether a debtor is experiencing financial difficulty.

The Interagency Guidance was jointly issued by the Board of Governors of the Federal Reserve System, the FDIC, the National Credit Union Administration, and the OCC.

As indicated in the examples in the Interagency Guidance, an entity must use judgment and consider the specific facts and circumstances, including the nature and functionality of the underlying collateral, in determining whether a loan is expected to be repaid solely through continued operation of the collateral. In OCC Supervisory Memorandum No. 2009-7, the OCC indicated that “[r]esidential real estate loan modifications without evidence of a sustained repayment capacity or cash flows from the borrower rely on the underlying collateral as the sole source of repayment and, as such, would likely be deemed collateral-dependent upon modification.”
12
Other factors that can affect an entity’s estimation of expected credit losses may include estimated prepayments on the financial asset (or group of financial assets) and expected repayments that may be received from sources other than the collateral (e.g., general recourse to the borrower or an embedded credit enhancement provided by a third-party guarantor).
