At certain intervals, the ovaries release an ovum, which passes through the Fallopian tube into the uterus. If, in this transit, it meets with sperm, a single sperm can enter and merge with the egg, fertilizing it. Corresponding equivalent among males is the male reproductive system.
The Average Annual Return is a percentage figure used to report a historical return of a given period (most commonly 3-, 5-, 10-year). The most common area using this figure is mutual funds. The deceptive part of Average Annual Return is how it is calculated. It is simply (Sum of Annual Returns) / (# of Years). For example, to earn a 10% annual return, a fund could perform both of the following ways: 1  Return 1: (+10% + +10% + +10% + +15% + +5%) / 5 = 10% Average Annual Return. 2  Return 2: (40% + +30% + -10% + +5% + -15%) / 5 = 10% Average Annual Return.
A loss instead of a profit is described as a negative return. Rate of return is a profit on an investment over a period of time, expressed as a proportion of the original investment. The time period is typically a year, in which case the rate of return is referred to as annual return. To compare returns over time periods of different lengths on an equal basis, it is useful to convert each return into an annual equivalent rate of return, or annualised return.
