A method, machine, article for reducing accounting volatility. A method can include: storing in memory terms of an agreement governing a contract, the terms including a specification of at least one measure of a variation in a rate of return corresponding to a return on an investment portfolio and a contract rate of return on an investment associated with the investment portfolio determined by using an amount of the at least one measure of the variation, wherein the amount of the measure of the variation changes over time; determining, by a digital computer accessing the memory and receiving market data including data corresponding to the at least one measure of the variation, the amount of the variation; determining, by the computer receiving market data including data on the rate of return on the investment portfolio and by using the amount of the variation, at least one of a contract rate of return on the investment associated with the investment portfolio and a contract value for the investment associated with the investment portfolio; and outputting, by the computer, at least one of the determined contract rate of return and the determined contract value. At least one measure of the variation includes at least one of: a variance, a covariance, a coefficient of variation, a standard deviation, a semi-variance, a semi-standard deviation, a third central moment, a fourth central moment, a duration, and a volatility index. |
