dedication

Dedication is cash-flow matching put into practice as a standing strategy: you set aside a specific portfolio of bonds and 'dedicate' it to paying off a particular set of liabilities, and nothing else. The dedicated bonds are chosen so their incoming cash — coupons and maturities — covers the outgoing payments date by date. Once built, the portfolio is left alone to run off against the liabilities it was created to fund. The word captures the spirit: those assets have a single job and are walled off from everything else.

How it works in detail: you start from the liability schedule and solve, usually by computer, for the cheapest bundle of available bonds whose cash flows always stay at or above the amounts due in each period, with any small surpluses carried forward or reinvested for very short periods. A dedicated portfolio set up to fund 30 years of pension payments, for instance, holds bonds maturing across all 30 years so that each year's pensions are met by that year's bond income without ever touching the rest of the fund. Because the match is built in cash terms, day-to-day movements in bond prices and interest rates do not disturb it.

Why it matters: dedication is how pension funds and insurers lock down a block of certain, predictable liabilities so that the people relying on those payments can sleep at night — the money is ring-fenced and accounted for. It is a close cousin of immunization but more concrete: immunization matches a summary statistic (duration) and tolerates buying and selling along the way, while dedication matches the actual cash and holds to maturity. The trade-off is the same as cash-flow matching: it is safe and simple to monitor but rigid and potentially more expensive, and it only works cleanly when the liabilities really are fixed. Insurers therefore dedicate the certain core and manage the uncertain remainder more dynamically.
