News release: “The Federal Reserve Board on Tuesday requested public comment on proposed changes to the methodology for calculating the imputed costs, collectively known as the private sector adjustment factor (PSAF), that are considered when setting fees and measuring cost recovery for certain payment services provided to depository institutions (DIs). The comment period ends on May 29, 2009. Specifically, the Board requests comment on its proposal to replace the current correspondent bank model underlying the PSAF calculation with a model based on elements derived from publicly traded firms more broadly.”
