Dik Clark and Ed McMahon show up at your door to announce you have won the Publisher?s Clearinghouse Sweepstakes. The $5,000,000 prize will be paid out as annual payments over 20 years via a payment of $250,000 at the end of each year. If the current interest rate for risk-free annuities is 5%, compounded annually, what lump sum amount today would equal the present value of this 20-year annuity.
