The arrays described in these two appendices differonly in the applicable mortality tables. For the static method,the 2000 mortality table is assumed for all future years. In thetrended method (Appendix D), projections of future mortalitytables are used.Table C.2.1 is a segment of the male lives array. We assumedthat the initial PD claimant population consisted of 750 malesand 250 females. A corresponding array was used for the femaleclaimants.
