The document provides guidance on improving the transparency of federal spending data. It establishes an October 1, 2010 deadline for agencies to begin sub-award reporting and to improve the quality, completeness and accuracy of spending data on the USAspending.gov website. Agencies will be required to monitor and report on metrics to measure progress in improving data quality over time, with a goal of 100% complete, accurate and timely data by the end of FY2011. OMB will issue additional guidance to help agencies implement sub-award reporting and will work with them to enhance transparency of federal spending information.
