THE CARNEGIE FOUNDATION FOR THE 

 ADVANCEMENT OF TEACHING ' 



THE ACTUARIAL SIDE OF THE RETIRING 

 ALLOWANCE SYSTEM 



The foundation has now had four years 

 of history. It seems, therefore, desirable to 

 examine as critically as possible the experi- 

 ence gained in this interval. It will be re- 

 membered that in each report emphasis has 

 been laid upon the fact that the income of 

 the foundation could sustain permanently 

 a satisfactory retiring allowance system for 

 only a limited number of teachers and that 

 it was desirable to determine at as early a 

 date as practicable the approximate load 

 the income could carry ; or, put in another 

 way, to determine the number of teachers 

 as well as the number of institutions which 

 the foundation might safely include in the 

 retiring allowance system. 



For the sake of continuity I venture to 

 state in some detail the process through 

 which the trustees have gone. 



When the first $10,000,000, with its in- 

 come of $500,000, was placed in the hands 

 of the trustees, the problem before them 

 presented a variety of factors, some of 

 which were of an actuarial nature, but 

 mainly the factors were of an educational 

 and social character. 



From the actuarial standpoint the prob- 

 lem could be stated in several ways. Per- 

 haps the most simple way to state it is in 

 the following terms. Assuming one thou- 

 sand college professors at an average age 

 of forty-seven, assuming three fourths of
