Gains or losses realized by the state insurance fund as a result of sales or dispositions pursuant to the authorization and direction of section eighty-seven-a, eighty-seven-b, eighty-seven-bb, eighty-seven-c, or eighty-seven-f of this chapter shall be transferred to a special asset account to be known as the deferred charge on account of security exchanges and shall be amortized within such account on a basis which matches as nearly as possible all gains or losses so realized against any increase or decrease in income resulting from the reinvestment of the proceeds of such sales or dispositions, provided that the period of amortization of the gain or loss resulting from the sale or disposition of each investment shall not be longer than the unexpired period from the date of such sale or disposition to the maturity of the investment so sold or disposed of, or on such other basis as the superintendent of financial services may authorize in his discretion.
