April 1, 2008: Beginning with the release of March 2008 data in the Federal Reserve's monthly G.17 Statistical Release, monthly releases will be based on a six-month reporting window: One month of new data will be reported, and the previous five months of data will be revised. For example, the monthly release to be issued on April 16, 2008 will include new data for March and revised data for October 2007 through February 2008. Previously, the monthly releases were issued with a four-month reporting window, which covered one month of new data and revisions to the previous three months of data.
