ABC wishes to immunize the portfolio from interest rate risk. The assets are $24,000,000 with a "duration" of 10 years; there is $16,000,000 in liabilities. You have 2 liability choices of: 1) a zero coupon bond yielding 6% and a maturity of 14 years and 2) a 199 year bond yielding 6.67%. How much would you recommend for each type of liability?
