The effective, or true, annual rate of return. The APY is the rate actually
earned or paid in one year, taking into account the affect of compounding. The APY is calculated by taking
one plus the periodic rate and raising it to the number of periods in a year. For example, a 1% per month rate
has an APY of 12.68% (1.01^12).
