Smaller project frees up funds at t = 0 for investment. The higher the opportunity cost, the more valuable these funds, so high k favors small projects.2. T

NPV should be used to choose between mutually exclusive projects.11 - 33Copyright 2001 by Harcourt, Inc.All rights reserved.Managers like rates-prefer IRR to NPV comparisons. Can we give them a better IR

24、R?Yes, MIRR is the discount rate thatcauses the PV of a projects terminalvalue (TV) to equal the PV of costs.TV is found by compounding inflowsat WACC.Thus, MIRR assumes cash inflows are reinvested at WACC.11 - 34Copyright 2001 by Harcourt, Inc.All rights reserved.MIRR = 16.5%10.080.060.0012310% 66.
