(i)#
the balance in the Federal Hospital Insurance Trust Fund, reduced by the outstanding amount of any loan (including interest thereon) theretofore made to such Trust Fund under this subsection, as of the last day of the second month preceding such month, to
(ii)#
the amount obtained by multiplying by twelve the total amount which (as estimated by the Secretary) will be paid from the Federal Hospital Insurance Trust Fund during the month for which such ratio is to be determined (other than payments of interest on, or repayments of loans from another Trust Fund under this subsection), and reducing the amount of any transfers to the Railroad Retirement Account by the amount of any transfer into the Hospital Insurance Trust Fund from that Account.
