See the review of the first edition (2007), to which I will only add that the book has been approved by the Society of Actuaries, as can be seen from their syllabus for the Financial Mathematics exam.
In addition to a new publisher, the main change in this edition is the addition of a Student Solutions Manual, which contains "detailed solutions to all the odd-numbered problems. There are solutions to 239 problems, and sometimes more than one way to reach the answer is presented." Beyond that, the changes are minor: correcting errors, changing the wording here and there, and modifying a couple of examples that proved troublesome in class. Finally, the book's move to the MAA has brought with it a welcome reduction in price!
