The New England Patriots plan to provide a retirement annuity for their coach, Bill Belichick, who will retire in 10 years. When he retires, he will receive an end-of-year annuity of $150,000 for 20 years. In order to fund Bills annuity, the Patriots plan to make equal annual end-of-year deposits into an account that will earn 7% per year. When the 20-year distribution period begins, they will move the money into a different account that will earn 10% per year. There will be no money left in the account at the end of 20 years. Note that the first deposit will be at the end of year 1 and the first distribution payment will be at the end of year 11.
