The year 1907 witnessed several important changes in the Post Office Insurance Fund made on the recommendation of the Government Actuary. These were: (1) That the sums eventually payable in respect of policies in existence on 31st March, 1907, in the Life Branch of the Fund were increased by 10 per cent and that the premia payable in respect of sums assured in that branch after that date would be correspondingly reduced. The rates of premia for Life Insurance were revised accordingly. (2) That a life policy, with monthly payments payable till death, was allowed to be converted into a life policy with monthly payments payable to a specified age or into a fully paid up policy payable at death. (3) That an endowment policy might be converted into a paid-up policy payable at some anterior date or at death, if earlier. (4) That insurants could reduce their monthly premia to any desired extent from any specified date. (5) That when a policy of either class was surrendered the policy holder should be given the full surrender value which on an actuarial calculation could be paid without loss to the Fund, instead of half that amount as hitherto given. (6) That the surrender value of a lapsed policy was payable at any time after default, on application being made for the same. (7) That the period up to which payment of arrears of premium or subscription was allowed for the revival of a policy of less than three years' duration was extended from three to six months. The tables of premia, introduced at the time the Fund was started, as already stated, were calculated on the mortality rates which had been deduced from the experience of the Uncovenanted Service Family Pension Fund, Bengal--a Fund which was confined to Europeans resident in India--there being no more reliable mortality statistics available for the purpose at the time. In 1909 the India Office Actuary, in his review on the operations of the Fund for the year 1907-08, noticed that, in view of the rapid growth of the scheme, it was necessary to revise the tables according to more accurate mortality statistics. In his review on the work of the Fund for 1908-09 the Actuary asked for detailed particulars of all the policies issued by the Fund since its institution in the form of statements, in order to enable him to deduce therefrom the necessary mortality rates, and thus prepare fresh tables of premia. These statistics were submitted with the Director-General's Annual Report on the operations of the Fund for the year 1910-11.
