Infinity times zero = zero
Ally Bank sent Rocky a letter apologizing for failing to pay interest on Leap Day 2008. Rocky grew excited at his unexpected windfall, until he sadly realized that anything times zero is still zero. And bank interest rates are extremely close to zero!
Rocky was also surprised by the Leap Day interest because his trusty Monroe Bond Calculator (vintage 1986) always assumed 30/360 for interest calculations.
Perhaps the biggest riddle is why the calculation error affects accounts “that were opened or matured between March 1 and December 31, 2008″ — since Leap Day was February 29, 2008.
Ally Bank, the retail banking subsidiary of GMAC, last week received an additional $3 Billion in US Government bail-out funds….perhaps for leap day interest payments?
