* $500 thousand or less.
\1\ In 1983, includes $329.3 million loss on sale of securities.
\2\ Starting in 1983, includes amounts from Postal Service.
\3\ For 1989 and 1990, includes transactions and balances of the HI and SMI Catastrophic Insurance trust funds, which began in 1989 and were abolished
  in 1990.
\4\ For years after 1986, receipts for kidney dialysis.
\5\ For years after 2006, includes outlays for vocational rehabilitation.
\6\ For years after 2006, outlays for peer review organizations are included in the benefit payments line.
Note: Offsetting collections from Federal sources that are credited to the Old Age and Survivors insurance (OASI) account and to the Supplementary
  Medical insurance (SMI) account are treated as offsets to cash outgo rather than as cash income. As a result, the partial transfer to SMI of Hospital
  Insurance (HI) home health is shown as benefit payments under HI rather than SMI. Similarly, transfers to Medicaid for payment of SMI premiums, which
  began in 2001, are shown as benefits under SMI.
