Examination of the figures in Tables XXXIX and XL with the corresponding Ultimate experiences suggested that the mortality of the early years of assurance was no better than that experienced after the expira- tion of 10 years. To test this, the data were recast into aggregate form showing in parallel columns the expected and actual deaths for quinquennial groups of ages attained in the full aggregate Table, and the truncated aggregate Tables excluding the first '5 and excluding the first 10 years of assurance respectively. The expected deaths were throughout calculated by means of the 0[M] Ultimate Table, thus eliminating the effect of selection. This experiment showed that, on the whole, and particularly at the younger attained ages, both for whole-life and for endow- ment assurances, a heavier rate of mortality was exhibited during the first 5 and first 10 years of assurance than in the Ultimate Tables excluding the first 10 years of assurance.
