Some series identifiers for data in the Financial Accounts have been changed to make the coding more consistent across instrument categories. In addition, new series have been added while others have been discontinued. A list of these code changes, effective with the release on September 25, 2013, is available online at: http://www.federalreserve.gov/Releases/Z1/preview/Code_changes. A preview of the coded tables is available through the "Z.1 Release Preview" link on this site. For a detailed description of the major changes see the "Release Highlights" page in the Financial Accounts Guide at http://www.federalreserve.gov/apps/fof/FOFHighlight.aspx.
