At the beginning of his current tax year, David invests $12,000 in original issue U.S. Treasury bonds with a $10,000 face value that mature in exactly 10 years. David receives $700 in interest ($350 every six months) from the Treasury bonds during the current year, and the yield to maturity on the bonds is 5 percent. (Round your intermediate calculations to the nearest whole dollar amount.) How much interest income will he report this year if he elects to amortize the bond premium?
