The Paper shows :–

(a) That if valuations are made using assurance factors taken to two places of decimals only, it is possible by means of a simple modification to bring out results varying inappreciably from those obtained by the standard methods and that such valuations can be made entirely by summation.

(b) That the process, which enables multiplications to be dispensed with, can be extended so as to be applicable to valuations by factors taken to three places of decimals.

It is also shown that a relation found to exist between net premiums at different rates of interest can be employed, in conjunction with either of the foregoing methods, to estimate the effect of changes in the valuation rate of interest.
