With respect to each retirement system, such unfunded accrued liability shall be known by the name consisting of the applicable abbreviation for the retirement system, as defined in paragraph three, four, five, six or seven of subdivision a of this section, followed by the calendar year as of which the unfunded accrued liability was established, followed by the term "UAL adjustment".

         (ii)   Each post-2010 UAL adjustment for each retirement system shall be amortized in equal installments payable or creditable, as determined by the actuary, as follows:

            (A)   that portion of a post-2010 UAL adjustment which is attributable to actuarial gains or losses, as determined by the actuary, shall be amortized in fourteen annual installments, as determined by the actuary, payable or creditable over a period of fifteen fiscal years following the June thirtieth as of which the unfunded accrued liability was established, with payments or credits commencing with the second fiscal year succeeding the June thirtieth as of which the unfunded accrued liability was established, provided, however, that the portion of a post-2010 UAL adjustment which is attributable to actuarial gains and losses shall be an amount equal to the total amount of such post-2010 UAL adjustment minus an amount equal to the sum of the portions of such post-2010 UAL adjustment, if any, which are attributable to (1) changes in the valuation rate of interest, changes in actuarial tables and changes in actuarial methods, as determined by the actuary pursuant to item (B) of this subparagraph, and (2) recently enacted changes in benefits which were not incorporated in the unfunded accrued liability established as of the preceding June thirtieth, as determined by the actuary pursuant to item (C) of this subparagraph;

            (B)   that portion of a post-2010 UAL adjustment which is attributable to changes in the valuation rate of interest, changes in actuarial tables or changes in actuarial methods, as determined by the actuary, shall be amortized in nineteen annual installments, as determined by the actuary, payable or creditable over a period of twenty fiscal years following the June thirtieth as of which the unfunded accrued liability was established, with payments or credits commencing with the second fiscal year succeeding the June thirtieth as of which the unfunded accrued liability was established; or

            (C)   that portion of a post-2010 UAL adjustment which is attributable to recently enacted changes in benefits which were not incorporated in the unfunded accrued liability established as of the preceding June thirtieth, as determined by the actuary, shall, unless an amortization period of a different length is specified by the law enacting such benefit changes, be payable or creditable in annual installments over a period of fiscal years comparable in length to the number of years which is one less than the number of years of the remaining working lifetimes of members covered by the benefit changes, as determined by the actuary, with the payment or credit of such annual installments commencing with the second fiscal year succeeding the June thirtieth as of which the unfunded accrued liability was established, provided, however, that where the length of the amortization period for the benefit changes is not specified in the law enacting the benefit changes, the actuary, in his or her discretion, and in lieu of amortizing the portion of the unfunded accrued liability attributable to the benefit changes over a period of fiscal years comparable in length to the number of years which is one less than the number of years of the remaining working lifetimes of members covered by the benefit changes, may select an amortization period that is reasonably consistent with past practice for amortizing unfunded accrued liability attributable to the particular type of benefit changes.

      (4)   Notwithstanding any other provision of law to the contrary, with respect to any installment of an unfunded accrued liability or an unfunded accrued liability adjustment, in the event that such retirement system has more than one responsible obligor, the actuary for that retirement system shall determine and shall allocate to each such responsible obligor its share of that installment, as determined to be appropriate by the actuary. Each responsible obligor's share of each such installment shall be either a charge or a credit with respect to such responsible obligor for the applicable fiscal year.

      (5)   For each fiscal year, commencing with the two thousand eleven – two thousand twelve fiscal year, the actuary shall determine whether the sum of the charges and credits applicable to each responsible obligor for such fiscal year with respect to the applicable retirement system shall constitute a total charge or a total credit. Where such amount for such responsible obligor for such fiscal year with respect to such retirement system is a total charge, the responsible obligor shall pay an amount equal to such total charge to the retirement system in a timely manner, as required by paragraph six of this subdivision. Where such amount for such responsible obligor for such fiscal year with respect to such retirement system is a total credit, the amount of employer contributions otherwise payable by such responsible obligor to such retirement system for such fiscal year pursuant to applicable provisions of law, as determined by the actuary, shall be reduced by the amount of such total credit, provided, however, that such total amount of employer contributions otherwise payable by such responsible obligor to such retirement system for such fiscal year shall not be reduced below an amount equivalent to the amount payable by such responsible obligor for such fiscal year for administrative expenses, as determined by the actuary in accordance with the provisions of subdivision f of section 13-103 of this title for NYCERS, subdivision h of section 13-216 of this title for the PPF, subdivision d of section 13-518 of this title for the NYCTRS or paragraph (e) of subdivision twenty-three of section twenty-five hundred seventy-five of the education law for BERS, and shall not be reduced below zero for the FPF, provided further, that where a total credit for a responsible obligor with respect to a retirement system has been offset against employer contributions otherwise payable by such obligor to such retirement system for such fiscal year by the maximum amount permissible pursuant to the preceding provisions of this paragraph, and all or a portion of such credit remains after such offset, the remaining credit shall be carried forward, together with interest calculated on such amount at the valuation rate of interest, as a credit for such obligor for the following fiscal year, as determined by the actuary.

      (6)   All responsible obligors shall make all unfunded accrued liability payments to a retirement system required pursuant to the provisions of this subdivision in accordance with the time of payment requirements set forth in subdivision c of section 13-133 of this title for NYCERS, subdivision c of section 13-231 of this title for the PPF, subdivision c of section 13-334 of this title for the FPF, subdivision (c) of section 13-533 of this title for the NYCTRS or paragraph (j) of subdivision sixteen of section twenty-five hundred seventy-five of the education law for BERS.

      (2)   In each fiscal year succeeding such June thirtieth, one of such recomputed installments shall be paid by or credited to, as the case may be, the responsible obligor or responsible obligors with respect to such retirement system in the same manner as the corresponding prior installments were paid or credited, until all such remaining installments are paid or credited in full; provided, however, that until all such installments are so disposed of, they shall be recomputed and paid or credited in recomputed form pursuant to this subdivision for each subsequent change in such valuation rate.
