Today’s uncertain financial markets could affect foundations’ future grantmaking capacities. We review foundations’ financial decision-making patterns and their effect on foundations’ assets, longevity goals, and payouts. Using three fictional foundations with different longevity goals and grantmaking preferences, we demonstrate the delicate balance and tight nexus between asset management strategies, payout rates, and longevity. To do so, we perform stochastic Monte Carlo simulations of multiple foundation life cycles, conducted under diverse capital market scenarios. The findings suggest that foundations should (a) readjust their return expectations to today’s less favorable markets; (b) reduce their reliance on past portfolios’ investment returns or unique “success stories” in making decisions; (c) appreciate the strong interdependence between portfolio-mix, payout rates, and longevity; (d) consider effects of their particular mission/problem area on these parameters; and (e) use tailored projection analyses that simulate various investment strategies, payouts rates, and longevity to meet their grantmaking goals.

Fred Bocock was examining the performance of the Energy Hedge Fund and the Energy Portfolio, a hedge fund and a mutual fund respectively, which he manages. Bocock had become increasingly aware that absolute returns or relative returns (returns relative to a benchmark) may not adequately capture his performance and some measure of risk-adjusted performance was necessary. The Dynamis Energy Hedge Fund extends the discussion of performance evaluation into the hedge fund arena. (See “Zeus Asset Management,” UVA-F-1232, for an examination of performance evaluation techniques in the mutual funds arena.) More broadly, the case engages students in discussions on what hedge funds are, what investment strategies they use, and who their investors are. Since the portfolio manager of Dynamis manages both an oil sector equity mutual fund and an oil sector hedge fund, the case allows for a comparison between a hedge fund and a mutual fund. Students should consider the pros and cons of evaluating the performance of the oil stock mutual fund against a number of oil sector stock indices as well as against a number of generic indices, such as the S&P 500 Index. The use of futures, options, shorts, and leverage by hedge funds makes it a lot more difficult to measure their performance. The case comes with a spreadsheet that contains data on the energy mutual fund, the Dynamis hedge fund, and several relevant indices.

Optimization is the core of transportation asset management, but current optimization approaches are still in the stage of single infrastructure management, which seriously hinders the development and application of transportation asset management. This paper establishes a comprehensive multi-infrastructure optimization model for transportation assets consisting of roads and bridges, which is aimed at achieving the goal of transportation asset comfort, integrity, and security, taking budget funds as constraint conditions, and applying the optimization technique of goal programming and integer programming. An interactive fuzzy linear-weighted optimum-order algorithm is presented to solve the comprehensive optimization model. Finally, the comprehensive multi-infrastructure optimization model and algorithm are verified to be effective by practical data in a case study. The results indicate that the model and algorithm can provide a satisfactory and reasonable maintenance and rehabilitation schedule for transportation asset management agencies.
