During the inflationary period of the past ten years, and particularly during the more violent phase of the past five years, the most immediate and pressing problem of the investment managers of funds has been to attempt to increase income at a rate commensurate with the decrease experienced in the purchasing power of the income received. Most funds have succeeded only partially in maintaining their income as expressed in terms of what that income can accomplish. Some, however, have been much more successful in this respect than have others. The reasons behind this variation in results afford an interesting picture of conflicting investment theories and practices. In speaking of endowments, or endowed funds, or of funds, it is important to realize that one is not speaking of a homogeneous entity, but rather of a group of capital aggregations having some, but far from all, common characteristics. It is, therefore, not possible to speak with definiteness and exactness of the total dollar amount of such endowed funds, as one can speak, for example, of the total of commercial bank deposits. The total size of in this country is conditioned to a considerable extent by the definition applied to endowments. Even after a satisfactory definition has been agreed upon, there still remains the fact that there is no central reporting agency or association having contacts with endowment or pension funds. In general, endowments fall into one of several generic groupings. Institutions of higher education, chiefly colleges and universities, form one such group. The I95I World Almanac' lists I93 colleges with endowments of 2 million dollars or more, the total endowments of these I93 colleges having a reported value in excess of i12 billion dollars. Philanthropic foundations with assets of i million dollars or more are listed in the I95I World Almanac in the number of 35. Their total assets exceed i2 billion dollars.2 Many hospitals depend upon income from endowment to help meet annual operating deficits. There are over 6,500 registered hospitals in the United States,3 and although their total of funds is not available, there are many metropolitan hospitals whose known endowments run into multiple millions of dollars. The growth of pension fund assets is a relatively new phenomenon. No *A.B. I926, Dartmouth College. Author, BANKER'S HANDBOOK OF BOND INVESTMENT (1939).
