McClenahan - Insurance Profitability Flashcards
2 ways to measure results of an insurer
Profit
Rate of return
Profit
absolute number
- can be used to pay dividends, grow company, etc
- investors & management are interested in profit
- hard to compare companies by looking at just profit
Rate of return
expresses profit as percentage of a particular base
- since rate of return is relative to a base, it is a measure of efficiency and can be used to compare companies
- more efficient companies are preferable
potential bases for rate of return
Equity
Assets
Sales
appropriate denominator to measure economic efficiency
Assets
-regulators focus on __ when looking at return of insurers
rate of return
rate regulation is
prospective
if applied retrospectively
single year of experience is not sufficient to assess the true profitability of the business
-example: low frequency, high severity lines require many years of experience to determine average profitability as most years have no/low losses whereas few years would result in terrible loss experience
investment income from policyholder funds
should be recognized in premium calculations
- arises from fact that premiums are paid by policyholder before losses and expenses are paid by insurer
- PH is therefore potentially losing out on some investment income and should receive credit for this
Opportunity cost
lost investment income
Opportunity cost is affected by 2 factors
- LOB: some lines have longer intervals before losses are paid; the opportunity cost in these cases are greater since more investment income could have been earned
- cash needed to support infrastructure of insurer: cash can not be invested; since most of the cash tied up in infrastructure was provided by premiums of prior PHs and current insureds are benefiting from these assets, they should not receive credit for the investment income from money that would be theoretically needed to pay for these
Calculation of opportunity cost should be made at and why
risk free rate
-insurer is probably earning a return other than risk free when investing the money but PH is not exposed to any of the risk of insurer’s investment ie if insurer speculates and loses money, PHs do not have to provide for the shortfall
investment income on total surplus needs to be segmented into
Investment income from PH funds
Investment income from shareholder funds
premium credit should only be given for investment income of
& why
PH funds
- PHs should not receive benefit from investment of surplus:
1. surplus is not owned by PHs, but rather the owners of insurer
2. including surplus will penalize high surplus insurers as they will need to charge lower premiums
Calculating opportunity cost in general
Sum (PV of cashflows)
PV cashflow = (premium – loss – expense)/(1+rf)^t
-this number does not represent the money expected to be earned by insurer -> insurer should expect to earn more than risk free rate on its investments
