This period, some 354 codes (and therefore a larger number of series) have been renamed. A list of changed codes is available in a separate Data Buffet News article. We will announce series changes later.
The following is quoted from the written documentation for the 2010:Q2 release. Additional commentary may be found in footnotes attached to each Z.1 table. The "coded tables" are marked with numeric identifiers from which the DataBuffet.com mnemonics are derived.
The documentation field of each Data Buffet time series identifies at least one Z.1 table in which the series may be found; however, a series may appear in up to six cross-referenced tables. Use the "find in catalog" search mode to locate them all.
Data revisions and other changes
The statistics in the attached tables reflect the use of new or revised source data. Most significant revisions appear in recent quarters; however, new source information resulted in changes to data for earlier periods.
1. Many nine-digit flow of funds mnemonics have been changed to make the coding more consistent across instrument categories. A list of these code changes is available online at: http://www.federalreserve.gov/Releases/Z1/preview/Code_changes/ [See also related Data Buffet News article.]
2. Seasonal factors for quarterly flows have been recalculated for the period 2000:Q1 forward. The seasonal factors were generated using the X-12- ARIMA/88 seasonal adjustment program from Statistics Canada. The seasonals of several series received special treatment due to the recent financial crisis: seasonal factors for money market mutual fund assets and federal government deposits at the Federal Reserve and commercial banks were not revised; seasonal factors for depository institution reserves at the Federal Reserve were eliminated from 2000:Q1 forward; and seasonal factors were added to the rest of the world’s holdings of Treasury securities from 2000:Q1 forward.
3. The statistics in this publication reflect the annual revisions to the national income and product accounts (NIPAs) from 2007 forward released by the Bureau of Economic Analysis (BEA) of the Department of Commerce on July 30, 2010, and subsequent information for 2010:Q2 released on August 27, 2010. The August 2010 issue of the Survey of Current Business details the major features of this annual revision. The flow of funds table on saving and investment by sector (table F.8) has been redesigned to be consistent with the revised NIPA table 5.1 and with the Integrated Macroeconomic Accounts of the United States, jointly compiled by the Federal Reserve Board and the BEA.
4. Data for investment and depreciation flows of all sectors, and capital stocks for the household, nonfarm nonfinancial corporate business, and nonfarm noncorporate business sectors have been revised to reflect updated annual estimates of fixed assets from the BEA.
5. The household sector (table F.100) has been modified to include an additional capital expenditure for nonproduced nonfinancial assets (net), which represents the sale of land by individuals to state and local governments.
6. Revisions to the rest of the world sector (tables F.107 and L.107) reflect new estimates of the balance of payments and the international investment position from the BEA for 1976 through 2009. The new estimates are detailed in the July 2010 issue of the Survey of Current Business.
7. Federal funds and security repurchase agreements in the rest of the world sector (tables F.107 and L.107) has been revised to net out securities sold under agreements to repurchase.
8. The instrument table "Gold and Official Foreign Exchange Holdings" (tables F.200 and L.200) has been renamed to "U.S. Official Reserve Assets" and reorganized to be consistent with revised international accounting standards in the System of National Accounts 2008 (SNA2008). As a result, special drawing right (SDR) allocations have been added as a liability of the federal government and an asset of the rest of the world (tables F.106, F.107, L.106, and L.107). Also, SDR holdings are now shown as a liability of the rest of the world on table L.200. The May 2010 issue of BEA’s Survey of Current Business provides a description of the new treatment of SDRs under the SNA2008.
