Differing Points of View
• A US life insurance company will calculate at least three reserve values for every policy every financial reporting period.– Statutory reserve using methods specified by
state insurance departments– GAAP reserve using methods specified by the
Financial Accounting Standards Board (FASB)
– Tax reserve using methods specified in the Internal Revenue Code

• The premium each year is $115
• The annual interest rate is 4%
• The probability of death in the – First year is 0.0011– Second year is 0.0012

Benefit Reserve Calculation
• Calculate the benefit reserve immediately after the first premium payment.
• Assume premium is paid at the beginning of each year.
• Assume death benefits are paid at the end of each year.
October 5, 2006 Purdue University
Present value of future benefits
The expected value of each benefit payment after the valuation date is discounted with interest to the date of valuation.
[100,000 x 0.0011 ]/ (1.04)
+ [100,000 x (1 – 0.0011) x 0.0012] / ((1.04)^2)
= 216.59
October 5, 2006 Purdue University
Present value of future premium
Each premium after the valuation date is discounted back to the date of valuation.
In this example, only one premium remains to be paid.
115 x (1- 0.0011) / (1.04) = 110.46
October 5, 2006 Purdue University
Benefit Reserve
216.59 – 110.46 = 106.13
• $115 premium was received.
• $106.13 is reserved for expected benefit payments.
• If no deaths occur the reported income in year one is $115.00 - $106.13 or $8.87.
October 5, 2006 Purdue University
Assumptions
• Mortality rates
• Interest rates
• Premium is paid at the beginning of each policy year.
• Death benefits are paid at the end of each policy year.
