Course Overview

 

What is an interest rate? How is the value of a corporate bond or a share of common stock determined? How big will the mortgage payment of a homeowner be each month, and how is that affected by differing interest rates, or different frequencies of payments? What are the financial calculations underlying retirement plans and annuities? These and other questions can be straight-forwardly answered with a basic understanding of an important financial and actuarial topic: the theory of interest. In essence, you can think of Math 210 as a first course in financial mathematics; as such, you will find this course to be a mathematical gateway for all your future actuarial science and finance courses.

 

We will cover most of the material in the Broverman text, in the process thoroughly exploring the mathematical theory of interest. Some of the specific topics and concepts covered will include: interest and discount rates, simple versus compound interest, nominal versus effective rates, present value, annuities and perpetuities of many types, yield rates, loan amortization schedules and sinking funds, the pricing of financial instruments such as stocks and bonds, duration and convexity, and short sales. Other topics may be covered, depending upon time constraints. Emphasis will be placed on the ability to understand and solve problems dealing with these concepts. We will also discuss the broader financial and actuarial contexts and implications of this material.

 

This course will help you prepare for the interest theory material on the Exam 2/FM national actuarial examination, co-sponsored by the Casualty Actuarial Society and the Society of Actuaries.

 

Accessibility Statement

 

To insure that disability-related concerns are properly addressed throughout the semester, students with disabilities who require reasonable accommodations to participate in this class are asked to contact me within the first two weeks of class.

 

Course Schedule

 

Some key dates for the class are noted below:

 

August 26 (Tuesday)

First day of class: Introduction and Motivation

September 25 (Thursday)

Exam # 1

October 30 (Thursday)

Exam # 2

December 9 (Thursday)

Last day of class

December 17 (Wednesday, 8 am)

Exam # 3

 

In most non-exam weeks, there will be a homework assignment and one or more short in-class or other assignments. In addition, practicing actuaries will be invited to give guest presentations to the class on several occasions during the semester.

 

Grading

 

Course grades will be determined based on the following weights:

 

Homework assignments

20 %

In-class/other assignments

5 %

Exams

75 % (25% each)

 

Exams may not be made up or taken at different times, except in extremis. In general, the grade weight for a missed exam (provided there is a valid excuse) will accrue equally to any remaining exams. A missed in-class or homework assignment may not be made up. However, in calculating your course score and grade, your worst homework assignment score will be dropped. Thus, if you miss one homework assignment, it will count as your drop. Similarly, your two worst in-class/other assignment scores will be dropped. Class attendance is expected; serious attendance problems may result in a grade lower than that indicated by the weighting system above.

 

Please note that the final exam schedule is prescribed by the university; in general, instructors are not permitted to change the final exam timing of their courses.
