As was pointed out recently in the Nihon Keizai Shimbun by Koizumi-government economics minister Takenaka Heizo, what is missing in the proposal is anyadjustment in pension benefits or other measures to manage its costs.
The proposed regulations provide that if a taxpayer sells an interest in an S corporation or partnership interest on the installment method, anyadjustment to net gain is computed in the year of sale and is taken into account proportionately as each payment is received and gain is recognized.
