Advantages of high deductible plans (5)
Per aggregate XS losses under the LR approach
per aggregate XS loss = prem * ELR * (1 - per occurrence charge) * per aggregate charge
Advantages of the LR approach to estimating XS losses (3)
Disadvantages of the LR approach to estimating XS losses (2)
2. may not properly reflect account characteristics if development emerges differently due to exposures written
Reason limits should be indexed for inflation
allows combining multiple experience periods by keeping the proportion of deductible/excess losses constant about the limit
Advantages of the implied development approach to estimating XS losses (3)
Disadvantage of the implied development approach for estimating XS losses
does not explicitly recognize XS loss development
Limited tail factor formula using an inverse power curve
age-to-age factor = 1 + a * (starting age/12 + c) ^ -b
Advantage and disadvantage of using an inverse power curve for the limited tail factor selection
advantage: produces uniformly decreasing tail factors that are consistent for each limit
disadvantage: bias exists b/c each limit is extended to the same maturity
Limited LDF under the direct development approach for estimating XS losses
limited LDF = LDF * severity relativity at ultimate / severity relativity at time t
severity relativity = limited severity / unlimited severity
XS LDF under the direct development approach for estimating XS losses
LDF * ( 1 - severity relativity at ultimate ) / ( 1 - severity relativity at time t
Weighted average form of the direct development approach
LDF = severity relativity * limited LDF + ( 1 - severity relativity ) * XS LDF
Advantages of the direct development approach for estimating XS losses (2)
2. ensures consistency b/w limited and excess LDFs
Disadvantages of the direct development approach for estimating XS losses (2)
2. not possible to produce estimates if no losses have emerged
Credibility weighting/BF method for estimating XS losses
ultimate loss = losses to date + expected loss * (LDF - 1) / LDF
Advantages of the credibility weighting/BF method for estimating XS losses (3)
1, liabilities can be determined directly or indirectly
Disadvantage of the credibility weighting/BF method for estimating XS losses
ignores actual experience to the extent of the complement of credibility
What service revenue is and which claims the insurer collects service revenue on
service revenue = asset for revenue associated with servicing claims under a high deductible program
> > collect on claims below the deductible and below the aggregate limit
Service revenue asset (formula)
SRA = expected recoverables - known recoverables
expected recoverables = ( ultimate limited losses - ultimate XS of aggregate losses ) * loss multiplier
