  1. 01
    What is Net Present Value (NPV)?
    The present value of cash inflows minus the present value of cash outflows, discounted at the required rate of return.
    npv
  2. 02
    What is the NPV decision rule for independent projects?
    Accept if NPV > 0 (creates value); reject if NPV < 0.
    npv
  3. 03
    What is Internal Rate of Return (IRR)?
    The discount rate that sets a project’s NPV equal to zero.
    irr
  4. 04
    What is the IRR decision rule (conventional independent project)?
    Accept if IRR > required return (cost of capital); reject if IRR < required return.
    irr
  5. 05
    Why can IRR be misleading with mutually exclusive projects?
    IRR ignores scale and timing differences; NPV is preferred for ranking value creation.
    pitfalls
  6. 06
    What is the multiple-IRR problem?
    Nonconventional cash flows (sign changes more than once) can produce multiple IRRs, making the metric ambiguous.
    pitfalls
  7. 07
    What is the payback period?
    Time required to recover the initial investment from project cash flows (often undiscounted).
    payback
  8. 08
    What is a key weakness of the simple payback method?
    Ignores time value of money and cash flows after payback; arbitrary cutoff.
    payback
  9. 09
    What is discounted payback?
    Payback computed using discounted cash flows — accounts for time value but still ignores post-payback cash flows.
    payback
  10. 10
    If two projects are mutually exclusive and conflict on IRR vs NPV, which should you generally follow?
    NPV — it measures absolute value added at the cost of capital.
    decision
  11. 11
    What does a higher discount rate do to NPV of a normal project?
    Lowers NPV (future cash flows are discounted more heavily).
    npv
  12. 12
    What is the profitability index (PI)?
    PV of future cash flows / initial investment (or 1 + NPV/Investment) — useful under capital rationing.
