This paper is an empirical exploration of the determinants of the required credit spreads on highly leveraged transaction (HLT) loans. The analysis uses a multi-factor spread model to estimate the movement of loan spreads relative to spreads required in the (competing) corporate bond market as well as the significance of loan-specific characteristics in determining loan spreads. The empirical estimates are based on the Loan Pricing Corporation's database which consists of over 4000 loan transactions between 1987 and 1994. We find a positive HLT loan spread sensitivity to changes in spreads in the corporate bond market, but this sensitivity is significantly less than unity; indicating that the HLT loan market and high yield public debt market are not fully integrated. Furthermore, there is evidence that lenders augment, rather than substitute, loan yield spreads with additional fees for syndication, commitment and cancellation risks. In general syndicated loans have lower yield spreads than other HLT loan types.

This paper examines asset pricing theories for treasury bonds using longer maturities than previous studies and employing a simple multi-factor model. We allow bond factor loadings to vary over time according to term structure variables. The model examines not only the time variation in the expected returns of bonds but also their unexpected returns. This allows us to explicitly test some asset pricing restrictions which are difficult to study under existing frameworks. We confirm that the pure expectation theory of the term structure of interest rates is rejected by the data. Our empirical study of a two-factor model finds substantial evidence of time-varying term-premiums and factor loadings. The fact that factor loadings vary with long-term interest rates and yield spreads suggest that bond return volatilities are sensitive to interest rate levels.
