SPECIAL NOTICE

  Data on reserves and the monetary base have been revised to reflect the
  results of annual reviews of break factors and seasonal factors.  Revisions
  to seasonal factors start in August 1998, and they are the major source of
  revisions to the data.  Revisions to break factors begin in January 2005,
  and revisions to break-adjusted data do not exceed $100 million in any
  maintenance period.  The maximum revision to total reserves, nonborrowed
  reserves, required reserves, and the monetary base (Table 1) in any
  maintenance period was $1.6 billion; most revisions were less than $500
  million.  
  Break factors remove discontinuities (or �breaks�) associated with
  regulatory changes in reserve requirements, such as the annual indexations
  of the low-reserve tranche and the reserve requirement exemption levels.(1)
  Seasonal factors for required reserves and the surplus vault cash component
  of the monetary base have been reestimated with the revised break-adjusted
  data.
  A more detailed description of the methods for constructing break factors
  and seasonal factors is available under �Annual Review of Break and
  Seasonal Factors� on the Federal Reserve�s web site
  (http://www.federalreserve.gov/releases/h3/hist/).  Historical data, updated
  each week, are available there as well.  For paid electronic access to
  current and historical data, call STAT-USA at 1-800-782-8872 or
  202-482-1986.

1. The Monetary Control Act of 1980 established a reserve ratio of 3 percent
   against the first $25 million in net transaction deposits (low-reserve
   tranche) at each depository institution.  Since 1982, the low-reserve
   tranche has been indexed each January by 80 percent of the previous year�s
   (June 30 to June 30) growth rate of net transaction deposits at all
   depository institutions.  For all reserve maintenance periods ending in
   2006, the low-reserve tranche is $48.3 million. 
   Under the Garn-St Germain Depository Institutions Act of 1982, the first $2
   million of reservable liabilities of each depository institution was
   exempted from reserve requirements.  Since 1983, this exemption amount has
   been indexed each year by 80 percent of the rate of increase of the
   reservable liabilities at all depository institutions over the preceding
   year (June 30 to June 30).  For all reserve maintenance periods ending in
   2006, the reserve exemption level is $7.8 million.

 1. Reserves and monetary base figures incorporate adjustments for discontinuities, or "breaks", associated with regulatory changes in reserve 
    requirements. (For more information, see Table 3).
 2. Seasonally adjusted, break-adjusted total reserves equal seasonally adjusted, break-adjusted required reserves plus unadjusted excess 
    reserves. (Also, see footnote 2 on Table 2 and footnote 2 on Table 3.)
 3. Seasonally  adjusted, break-adjusted nonborrowed reserves equal seasonally adjusted, break-adjusted total reserves less unadjusted total
    borrowings of depository institutions from the Federal Reserve.
 4. Excess reserves NSA equals unadjusted total reserves (Table 2, column 1) less adjusted required reserves (Table 2, column 3).
 5. The seasonally adjusted, break-adjusted monetary base consists of (1) seasonally adjusted, break-adjusted total reserves plus (2)
    the seasonally adjusted currency component of the money stock plus (3), for all quarterly reporters on the "Report of Transaction 
    Accounts, Other Deposits and Vault Cash" and for all those weekly reporters whose vault cash exceeds their required reserves, the 
    seasonally adjusted, break-adjusted difference between current vault cash and the amount applied to satisfy current reserve requirements. 
    (Also see footnote 3 on Table 2 and footnote 4 on Table 3.)
 6. Prorated averages of biweekly averages.
 7. Averages of daily figures.

 1. Reflects actual required reserves, with no adjustments to eliminate the effects of discontinuities, or "breaks", associated with 
    regulatory changes in reserve requirements.
 2. Reserve balances with Federal Reserve Banks plus vault cash used to satisfy reserve requirements.
 3. The monetary base, not break-adjusted and not seasonally adjusted, consists of (1) total reserves plus (2) required clearing balances
    and adjustments to compensate for float at Federal Reserve Banks plus (3) the currency component of the money stock plus (4), for all 
    quarterly reporters on the "Report of Transaction Accounts, Other Deposits and Vault Cash" and for all those weekly reporters whose 
    vault cash exceeds their required reserves, the difference between current vault cash and the amount applied to satisfy current reserve 
    requirements. Currency and vault cash figures are measured over computation periods ending on Mondays.
 4. Excludes required clearing balances and adjustments to compensate for float and includes other off-balance sheet "as-of" adjustments.
 5. Vault cash eligible to satisfy reserve requirements. It includes only vault cash held by those banks and thrifts that are not exempt
    from reserve requirements. Dates refer to the maintenance periods in which the vault cash can be used to satisfy reserve requirements.
 6. All vault cash held during the lagged computation period by "bound" institutions (i.e., those whose required reserves exceed their vault 
    cash) plus the amount of vault cash applied during the maintenance period by "nonbound" institutions (i.e., those whose vault cash 
    exceeds their required reserves) to satisfy current reserve requirements.
 7. Total vault cash eligible to satisfy reserve requirements, held by depository institutions not exempt from reserve requirements, minus the
    amount used to satisfy reserve requirements.
 8. Consists of carryover only at depository institutions maintaining reserves on the basis of two-week maintenance periods. Reflects excess (+) 
    or deficit (-) reserves eligible to be carried forward into the two-week reserve maintenance period ending on the date shown.
 9. Prorated averages of biweekly averages.
10. Averages of daily figures.

 1. Figures reflect adjustments for discontinuities, or "breaks", associated with 
    regulatory changes in reserve requirements.
 2. Break-adjusted total reserves equal break-adjusted required reserves (Table 3, 
    column 3) plus excess reserves NSA (Table 1, column 5).
 3. To adjust required reserves for discontinuities due to regulatory changes in 
    in reserve requirements, a multiplicative procedure is used to estimate what 
    required reserves would have been in past periods had current reserve 
    requirements been in effect. Break-adjusted required reserves are equal to 
    break-adjusted required reserves against transactions deposits.
 4. The break-adjusted monetary base equals (1) break-adjusted total reserves plus 
    (2) the (unadjusted) currency component of the money stock plus (3), for all 
    quarterly reporters on the "Report of Transaction Accounts, Other Deposits and 
    Vault Cash" and for all those weekly reporters whose vault cash exceeds their 
    required reserves, the break-adjusted difference between current vault cash and 
    the amount applied to satisfy current reserve requirements.
 5. Prorated averages of biweekly averages.
 6. Averages of daily figures.
