Insights
Hospitals with strong finances increasingly use variable rate debt to reduce capital costs. Factors like bond insurance and higher profitability influence this trend, indicating a strategic financial management approach.
Area of Science:
- Healthcare Finance
- Capital Markets
- Financial Management
Background:
- Variable rate debt usage in healthcare bonds has significantly increased since 1995.
- In 2004, variable rate debt constituted 63.4% of healthcare bonds issued, up from 30.6% in 1995.
Purpose of the Study:
- To identify factors influencing hospitals' choice of variable rate debt over fixed rate debt.
- Investigate issuer characteristics, issue details, and credit spread implications.
Main Methods:
- Analyzed 230 tax-exempt bond issues from acute care hospitals and health systems (2000-2004).
- Employed a logistic regression model to differentiate between variable and fixed rate debt issuance.
Main Results:
- Bond insurance positively correlated with variable rate debt; callable features showed a negative association.
- Hospitals in certificate-of-need states with higher case mix acuity, profit margins, debt service coverage, and lower debt levels favored variable rate debt.
Conclusions:
- Financially strong hospitals utilize variable rate debt to lower capital costs.
- Improved education by investment bankers on interest rate savings may also contribute to this trend.
Background:
Recent trends show a greater usage of variable rate debt among health care bond issues. In 2004, 63.4% of the total health care bonds issued were variable rate compared with 30.6% in 1995 (Fitch Ratings, 2005).
Purpose:
The purpose of this study is to gain a better understanding of the underlying factors, credit spread, issue characteristics, and issuer factors behind why hospitals and health system borrowers select variable rate debt compared with fixed rate debt.
Methodology:
From 2000 to 2004, this study sampled 230 newly issued tax-exempt bonds issued by acute care hospitals and health care systems that included both variable and fixed rate debt issues. Using a logistic regression model, hospitals with variable rate debt issues were assigned a value of 1, whereas hospitals with fixed rate debt issues were assigned a value of 0.
Findings:
This study found a positive association between bond insurance and variable rate debt and a negative association between callable feature and variable rate debt. Facilities located in certificate-of-need states that possessed higher case mix acuity, earned higher profit margins, generated higher debt service coverage, and held less debt were more likely to issue variable rate debt.
Practice Implications:
Overall, hospital managers and board members of hospitals possessing a strong financial performance have an interest in utilizing variable rate debt to lower their cost of capital. In addition, this outcome may also reflect that investment bankers are doing a better job in educating senior hospital management about the interest rate savings benefit of variable rate compared with fixed rate debt.
