      <subfield code="a">It is basic actuarial knowledge that the pure premium of an insurance contract can be written as the product of the expected claim number and the expected claim ammount. Actuaries use credibility theory to incorporate the contract's individual experience into this calculation in a statistically optimal way. For many years, however, the use of credibility was limited to the frequency component. This paper reviews four different formulas incoporating frequency and severity into credibility calculations</subfield>
