e. None of the above

85 Regarding expensing an asset's cost immediately versus capitalizing the cost and depreciating it over time: All else the same, given a choice, a tax paying firm would generally prefer to
a. Capitalize the cost and depreciate, because this

A. true
b. false

A. true
b. false

90 If an investment has an NPV =0, then
a. this means the investor earned no money
b. this means the investor earned more than the required rate of return (i.e., cost of capital)
c. this means the investor earned less than the required rate of return (i.e., cost of capital)
d. this means the investor earned a return just equal to the required rate of return (i.e. the cost of capital rate at which the NPV was calculated)
