Inasmuch as we are dealing with calendar years and not with policy years, let us look at the matter on that basis. Taking the whole year's deaths during the calendar year on the supposition of a uniform distribution of deaths during the year (which is in accord with mean reserve valuations) we can assume that one-half will die before the anniversary and one-half...
