This case explores the intersection of asset allocation theory and corporate governance. Taro Tanaka, an investment manager at ABC Corp’s Defined Benefit (DB) pension fund, faces a structural crisis: the traditional "safe" portfolio of bonds is yielding negative real returns in an inflationary environment. To fulfill the fund’s long-term promise to 5,000 employees, Tanaka proposes shifting into Alternative Assets (Private Equity and Hedge Funds). However, he must confront a conservative Board of Trustees that views "safety" as the absence of short-term volatility.The case culminates in a fiduciary and ethical showdown: Is it riskier to embrace new, complex assets or to stick with a "safe" strategy that is mathematically certain to fail?
