1 Negative figure represents amounts lent to the OASI Trust Fund from the DI Trust Fund. Positive figures represent amounts repaid from the OASI Trust Fund to the DI Trust Fund. Transfers were not available until November 1982.

2 Income from taxation of benefits was not available until 1984.

3 Paid from the general fund of the Treasury. Includes transfers representing contributions that would have been paid on deemed wage credits for military service performed-traditionally split into "pre-1957" and "post-1956"-if such credits were considered covered wages. In 1983, a change in the financing basis for pre-1957 service resulted in a one-time transfer for past credits-adjustments to the initial 1983 transfer were made in 1985, 1990, 1995, and 2000. Additional adjustments are expected quinquennially thereafter.

4 Paid from the general fund of the Treasury. Includes costs of benefits to certain uninsured persons who attained age 72 before 1968.

5 Net interest includes net profits or losses on marketable investments. Administrative expenses are charged currently to the trust fund on an estimated basis, with a final adjustment, including interest, made in the following fiscal year. The amounts of these interest adjustments are included in net interest. Calendar years 1982-86 reflect interest on interfund borrowing.
