This study evaluates the association between the market value of banks
' common equity and fair value estimates disclosed under Statement of
Financial Accounting Standards No. 107, ''Disclosures about Fair Value
of Financial instruments.'' The results suggest that only the reporte
d fair values of investment securities have incremental explanatory po
wer relative to book value. No reliable evidence of incremental explan
atory power is found for the fair value disclosures of loans, deposits
, long-term debt or net off-balance sheet financial instruments. After
controlling for two competing indicators of value captured by the acc
rual accounting system, ROE and growth in book value, the fair value o
f securities no longer exhibits a significant association with market
value. Results from estimating a returns specification, which may impl
icitly control for correlated omitted variables, also exhibit no relia
ble evidence of significant incremental explanatory power in the fair
value estimates.
