In Chapter 2, page 72, section 2.7.1:
The unlabeled equation under point 3 on page 72 contains a "2" that should be an exponent. The equation should read:
(1 - c)2N - [c(1 - c)2]N - (1 - c)2N x (1 - c) - (1 - c)3N
In Chapter 2, page 74, section 2.7.3:
Equation 2.19 is missing the division operator "/" between "(365/12)" and "p," so it should read:
c = 100% - (1 - c')(365/12) / p
