On February 1, 2006, Weaver Corporation issued 7%, $100,000, 10-year bonds for $107,440. Weaver Corp. elected to amortize the premium using the straight-line method. The bonds are dated December 31, 2007, with interest payable on February 1 and August 1 of each year. Weaver retired all of these bonds on August 2, 2010, at 103. You have to calculate the unamortized bond premium on that date and determine how much gain or loss should be recognized on this bond retirement?
