Textbook
Actuarial Mathematics, 2nd Edition, by Bowers et al., published in 1997 by the Society of Actuaries. Only the portions of the book covered on the Casualty Actuarial Society/Society of Actuaries Course 3 examination will be covered in class. It is also recommended that you use Actex Manual for Course 3, published by Actex Publications, as a supplementary textbook. If you are planning to take Casualty Actuarial Society / Society of Actuaries Course 3 examination, you are encouraged to obtain both textbooks.


Objective
The objective of this class is to help you learn about actuarial models of life contingencies (i.e., financial random variables dependent on human life, such as life insurance payments, life annuity payments, pension payments, etc.). We will cover topics such as: survival distributions, life tables, mathematics of life insurance, life annuities, premiums, and reserves. These actuarial models are tested on the Casualty Actuarial Society / Society of Actuaries Course 3 examination, and form a key part of modern actuarial science.


Grading
There will be four tests and a final examination. You can have a make-up test, but a make-up will be made intentionally at least 20% more difficult. The final will count as 40% of your grade, and the best two of the four tests will count as 30% of your grade each. The grading scale will be as follows: 80% or better -- A, 70% to 80% -- B, 60% to 70% -- C, 50% to 60% -- D, below 50% -- F. You will also receive up to 20% extra credit for the better of the your two worst tests. You will be also given an opportunity for earning 10% extra credit for homework problems, and 10% extra credit for in class random quizes. While the grading scale may appear liberal, it is justified by the level of difficulty of the material.
