Synthetic Floating‐Rate Debt: An Example of an Asset‐Driven Liability Structure

An asset‐driven liability (ADL) structure is analogous to a liability‐driven investment (LDI) strategy. In both cases, the intent is to reduce the risk arising from a mismatch of assets and liabilities by aligning the interest rate sensitivity of cash flows on both sides of the balance sheet. Increasingly, defined‐benefit pension plans have adopted LDI strategies that reduce their equity assets and increase the average duration of their debt assets to better match the typical long duration of their retirement obligations to its employees. To illustrate the concept of ADL, the authors use the example of a corporate issue of traditional fixed‐rate debt that is transformed into synthetic floating‐rate debt using an interest rate swap (in which the corporation receives the fixed rate on the swap and pays at money market reference rate like three‐month LIBOR). The use of such long‐term, floating‐rate debt reduces interest rate risk when the firm has operating revenues that are positively correlated to the business cycle. However, a problem arises in that there is limited demand for such debt securities from institutional investors, many of which, because of LDI guidelines, prefer long‐term, fixed‐rate securities. Derivatives provide a way of resolving this mismatch between issuer and investor interests. In the article, the authors present a detailed example of the cash flows on the “receive‐fixed” interest rate swap (and its valuation for financial reporting) to show how the synthetic ADL debt structure obtains the desired outcome.     

Differential taxation and the equilibrium structure of interest rates

Equilibrium coupon bond pricing relationships given differential taxation are derived under uncertainty assuming that both corporate and municipal bonds were originally issued at par but are currently selling at a discount. The impact of differential taxation upon the term structure and coupon structure of interest rates is investigated, while the tax structure of interest rates is uniquely characterized. Differential taxation substantially alters the prevailing equilibrium structure of interest rates.     

Rate-base valuation methods and firm efficiency

The economic performance of public utilities under different rate-base valuation methods is examined in this paper. A unique procedure, involving Ordinary Least Squares regression analysis, examined data for all usable firms in states which have changed rate-base methods since World War II. The sample consists of 20 electric firms extending over 30 years of time-series data. Equations for individual firms were run to capture the effects of changes on rate-base methods on capital intensity and capacity utilization on each separate business. Contrary to expectations, there was no clear pattern indicating that firms in the sample increased the rate of capital intensity when their rate-base method was changed to fair value from original cost. Similarly, expected excess capacity was not found under fair-value regulation. The general conclusion is that there is no reason to believe that different rate-base valuation methods induce allocative inefficiency. Nevertheless, inefficiency may already exist in regulated monopolies in the form of X-inefficiency.     

On inferring standard deviations from path dependent options

Path dependent option prices are employed to derive implied standard deviations of the underlying security price process without recourse to numerical procedures. We empirically illustrate our methodology by inferring the volatility of gold prices.
