Objective

The objective of this class is to help you learn about mathematical models in finance and investments, as utilized in the management as well as financial supervision of insurance enterprises and other financial intermediaries.

Grading

There will be a total of five tests. Any of the comprehensive tests (as indicated in the schedule) can count as a final. Because there will be many opportunities for testing and only the best three scores will affect the class grade (but with the opportunity for extra credit for two more tests), no make-up tests will be offered. The final will count as 40% of your grade, and the best two of the remaining tests will count as 30% of your grade each. You will also receive up to 10% extra credit for each of the remaining tests. The grading scale for will be as follows: 90% or better — A, 80% to 90% — B, 70% to 80% — C, 60% to 70% — D, below 60% — F. Past professional examinations can also serve as a guidance of what kind of material students can expect on the tests. You can find past Society of Actuaries examinations at: http://smartURL.it/pastSOAexams, and past Casualty Actuarial Society examinations at: http://smartURL.it/pastCASexams. However, the tests in this class will be quantitative only, no essay questions will be given. Even though questions will be quantitative only, students are encouraged to explain their work thoroughly. Students will also have an opportunity to earn extra credit by making presentations in class on the readings suggested in Canvas or other readings from Fellowship level examinations of the Society of Actuaries or the Casualty Actuarial Society. Those presentations must be set well in advance with Dr. Ostaszewski, and presentations scheduled at the last minuted before the end of the semester may be denied.

Class attendance

While this class does not have a strict formal attendance requirement, students who actively participate in class, and make a significant contribution may be granted extra credit. You are expected to attend classes and be involved in the learning process. If you must miss class due to an extended illness (3 or more consecutive class days) or bereavement, the Student Health Services and the Dean of Students Office can help. Please note this university policy: Excused Student Absences Due to Communicable Disease.
