I have been invited by the Council of the Institute of Actuaries to read a paper dealing with the general bearings of the New Experience Tables. The Unadjusted Data of the Assurance Experience are set forth in the three volumes published by the Joint Committee of the Institute of Actuaries and the Faculty of Actuaries in Scotland, comprising (1) Whole-Life Assurances—Participating and Non-Participating—Male Lives; (2) Whole-Life Assurances—Participating and Non-Participating—Female Lives; (3) Endowment Assurances and Minor Classes of Assurances—Male and Female Lives. The Joint Committee have also kindly placed at my disposal, in the preparation of this paper, the graduated results, so far as available; and the Monetary Tables which have been computed, and which are in course of being printed for publication.

On reading over my paper after it was published, I did not feel quite satisfied as to the accuracy of my approximate formula, given on page 235, for the adjustment of in respect of the excess of contributions included in the Table as constructed, so I have had the values of and , calculated. The constant summation of these columns, namely, and , will give the columnar values to be used for making accurate adjustments.
