1/ Beginning in 1983, includes transfers from general fund of Treasury repre-
senting contributions that would have been paid on deemed wage credits for
military service in 1957 and later, if such credits were considered to be
covered wages.
2/ Includes payments (1) in 1947-51 and in 1966 and later, for costs of non-
contributory wage credits for military service performed before 1957; (2) in
1971-82, for costs of deemed wage credits for military service performed after
1956; and (3) in 1968 and later, for costs of benefits to certain uninsured
persons who attained age 72 before 1968.
3/ Net interest includes net profits or losses on marketable investments.
Beginning in 1967, administrative expenses are charged currently to the trust
funds 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. For years prior to 1967, a description of the method
of accounting for administrative expenses is contained in the 1970 Annual
Report. Beginning in October 1973, the figures shown include relatively small
amounts of gifts to the funds. Net interest for 1983-86 reflects payments from
a borrowing trust fund to a lending trust fund for interest on amounts owed
under the interfund borrowing provisions. During 1983-90, interest paid from
the trust funds to the general fund on advance tax transfers is reflected. The
amount shown for 1985 includes an interest adjustment of $102.8 million on
unnegotiated checks issued before April 1985.
4/ Less than $500,000.
