The paper extends the main result of [1], that is, the construction of a K-immunization strategy with the highest convexity to a more general setting by dropping the key assumption of [1] stating that interest rate shocks ht to occur in a near future are proportional to the values of spot rates Yt plus 1, e.g. the condition (4) holds. Here, the interest rate shifts ht are allowed to be of the more general type (1) with known (to an investor) coefficients gt'S (usually estimated empirically based on historical data). The optimal portfolio Z* is found here by means of the K - T conditions. If the convexity of Z* exceeds that of any single payment at time when the liability has to be discharged, then Z* appears to be also the best K-immunization strategy yielding the maximal unanticipated rate of return due to shocks in spot rates.
