The following post comes to us from Elizabeth Blankespoor of the Graduate School of Business at Stanford University; Thomas Linsmeier of the Financial Accounting Standards Board; Kathy Petroni, Professor of Accounting at Michigan State University; and Catherine Shakespeare of the Ross School of Business at the University of Michigan.
In our paper, Fair Value Accounting for Financial Instruments: Does it improve the Association between Bank Leverage and Credit Risk?, which was recently made publicly available on SSRN, we contribute to the debate on whether financial instruments should be measured at fair value in financial statements. Accounting standard setters have been deliberating the role of fair values for financial instruments for decades. A fair value is the price at which two willing parties would exchange an asset or settle a liability. Starting after the savings and loan crisis in the late 1980s, the Financial Accounting Standards Board (FASB) has increased the extent to which financial instruments are recognized at fair value (see Godwin, Petroni, and Wahlen 1998). In 2010, the FASB proposed to require that all financial instruments be recognized at fair value, with limited exceptions for receivables and payables and some companies’ own debt (FASB 2010). The proposal was controversial, with over 2,800 comment letters submitted, the vast majority of which objected to the fair value measurement of loans, deposits, and financial liabilities. The FASB is redeliberating this project and has tentatively decided that all financial instruments should be measured at fair value except certain debt financial assets and most financial liabilities (including deposits), which would be measured at amortized cost (FASB 2011).
To empirically provide insight on the controversy, we assess whether a fair value leverage ratio can explain measures of a bank’s credit risk better than a leverage ratio based on a mixture of fair values and historical costs consistent with the mixed-attribute model of US Generally Accepted Accounting Principles (GAAP) and a leverage ratio based on even fewer fair values than GAAP, which is consistent with regulatory Tier 1 capital. We focus on balance sheet leverage because it is very commonly used for assessing firm risk. We define a bank’s credit risk as the risk that the bank defaults on its obligations, and we focus on credit risk because understanding a bank’s credit risk is essential to understanding its financial condition.
