"An Alternative Plan to Fix TBTF: Lay Big Banks' Subsidy Bare"(July 25), on Professor Cornelius Hurley's plan to account for implicit government subsidies, is an important contribution to the conversation on how to end Too Big to Fail.

Lower borrowing costs for the biggest institutions based on perceived government support encourage these institutions to grow larger and more systemically important. This dynamic also puts community banks at a competitive disadvantage.

As the article pointed out, a number of studies have concluded that the value of the "Too Big to Fail Subsidy" is staggering.

If the forthcoming Government Accountability Office study validates these findings, the results will underscore the sense in accounting for the subsidy.

In the meantime, legislators and regulators should give serious consideration to integrating Professor Hurley's plan into the emerging regulatory patchwork aimed at ending Too Big to Fail.
