twice the dollar amount of the actuarially adequate rate per enrollee age 65 and over as determined under section 1395r(a)(1) of this title for such month minus the dollar amount of the premium per enrollee for such month, as determined under section 1395r(a)(3) of this title , to the dollar amount of the premium per enrollee for such month, plus twice the dollar amount of the actuarially adequate rate per enrollee under age 65 as determined under section 1395r(a)(4) of this title for such month minus the dollar amount of the premium per enrollee for such month, as determined under section 1395r(a)(3) of this title , to the dollar amount of the premium per enrollee for such month; minus the aggregate amount of additional premium payments attributable to the application of section 1395r(i) of this title ; plus such sums as the Secretary deems necessary to place the Trust Fund, at the end of any fiscal year occurring after June 30, 1967 , in the same position in which it would have been at the end of such fiscal year if (A) a Government contribution representing the excess of the premiums deposited in the Trust Fund during the fiscal year ending June 30, 1967 , over the Government contribution actually appropriated to the Trust Fund during such fiscal year had been appropriated to it on June 30, 1967 , and (B) the Government contribution for premiums deposited in the Trust Fund after June 30, 1967 , had been appropriated to it when such premiums were deposited; plus a Government contribution equal to the amount of payment incentives payable under sections 1395w–4( o ) and 1395w–23( l )(3) of this title; plus a Government contribution equal to the estimated aggregate reduction in premiums payable under part B that results from establishing the premium at 15 percent of the actuarial rate (as would be determined in accordance with section 1395r(a)(1) of this title if the reference to “one-half” in such section were a reference to “100 percent”) under section 1395r(j) of this title instead of 25 percent of such rate (as so determined) for individuals enrolled only for the purpose of coverage of immunosuppressive drugs under section 1395 o (b) of this title.
