The unlabeled equation under point 3 on page 72 contains a "2" that should be an exponent. The equation should read:

`(1 - c)`^{2}N - [c(1 - c)^{2}]N - (1 - c)^{2}N x (1 - c) - (1 - c)^{3}N

Equation 2.19 is missing the division operator "/" between "(365/12)" and "p," so it should read:

`c = 100% - (1 - c')(365/12) / p`
