Question: Uncertainty about the exact lives of assets prevents precise maturity matching in an ex post (i.e., after the fact) sense even though it is possible to match maturities on an ex ante (expected) basis.
Answer Options:
a. True
b. False
Answer: a. True
Question: The “maturity matching,” or “self-liquidating,” approach to financing involves obtaining the funds for permanent current assets with a combination of long-term capital and short-term capital that varies depending on the level of interest rates. When short-term rates are relatively high, short-term assets will be financed with long-term debt to reduce costs.
Answer Options:
a. True
b. False
Answer: b. False
Question: A firm that follows an aggressive working capital financing approach uses primarily short-term credit and thus is more exposed to an unexpected increase in interest rates than is a firm that uses long-term capital and thus follows a conservative financing policy.
Answer Options:
a. True
b. False
Answer: a. True
Question: The relative profitability of a firm that employs an aggressive working capital financing policy will improve if the yield curve changes from upward sloping to downward sloping.
Answer Options:
a. True
b. False
Answer: b. False
Question: If the yield curve is upward sloping, then short-term debt will be cheaper than long-term debt. Thus, if a firm’s CFO expects the yield curve to continue to have an upward slope, this would tend to cause the current ratio to be relatively low, other things held constant.
Answer Options:
a. True
b. False
Answer: a. True
Question: The risk to the firm of borrowing using short-term credit is usually greater than if it used long-term debt. Added risk stems from (1) the greater variability of interest costs on short-term than long-term debt and (2) the fact that even if its long-term prospects are good, the firm’s lenders may not be willing to renew short-term loans if the firm is temporarily unable to repay those loans.
Answer Options:
a. True
b. False
Answer: a. True
