Jim and Jen are each 62 and hope to retire in 3 years. After retirement, they will receive $5,000 per month after taxes from Dunder Mifflin pension plans and $1,000 per month after taxes from Social Security. Unfortunately, their monthly living expenses are $15,000. Their social obligations preclude further economies. Jim and Jen have $1,200,000 invested in a highgrade corporate-bond mutual fund. Unfortunately, the after-tax return on the fund has dropped to 3.5% per year. The couple plans to make annual withdrawals from the fund to cover the difference between their pension and social security income and their living expenses. How long will the money last?
