Description: The management of the investments of an insurance enterprise has undergone a considerable evolution since the pioneering work of Redington in the mid 20th century. Best practices have evolved to incorporate ever more complex insurance liabilities, expanding investment asset classes and global market opportunities. Strategic asset allocation (SAA), liability driven investing, and other robust optimization approaches form the core of the professional management of insurance company investments.

Description: This paper presents the theory of immunization of investments to changes in interest rates and provides an extensive series of examples and formulas used in its implementation. Also presents some implications for investment behavior, product development, interest assumptions, valuation and adjusted earnings. Discussions of this paper are included.
