This case explores the decision that Bill Ackman, CEO and founder of the hedge fund Pershing Square Capital, was considering in late February 2020 about hedging the exposure of the fund's portfolio from the potential financial fallout ensuing from an extreme event like a global pandemic. Bill Ackman had become increasingly concerned about the hedge fund's exposure to a novel, highly infectious, and lethal coronavirus that was spreading across the globe. Ackman and his team needed to decide whether this was a risk worth hedging, and if so, which hedging instruments would best balance risk mitigation, explicit costs (fees and premia), opportunity costs, and the long-run objectives of the fund. Ackman and his team considered fully liquidating their portfolio, as well as hedging it with futures, options, and credit default swaps. For each alternative, they also needed to determine the optimal size and maturity of the hedging position, after accounting for uncertainty over the trajectory of the virus. This case provides students with ample opportunities to analyze and understand tail risk and how to manage it in practice, including explicit calculations of position sizing, costs, risks, and benefits of hedging alternatives.

This case examines modern endowment investment management through the lens of a leadership transition between Chief Investment Officers (CIOs). In March 2021, Paula Volent is about to step down as the CIO of the endowment of Bowdoin College after twenty-one years, and is preparing to meet with her successor, Niles Bryant, to plan for the transition. Under Volent's leadership, the endowment has grown from about $433 million to almost $1.8 billion while providing the college a consistent annual payout of between 4% and 5% of the value of the endowment to fund its operations. While returns have been exceptional under Volent's leadership (as compared for example to most other college and university endowments), she is acutely aware of the challenges ahead driven by capital markets conditions, including the persistently low level of real and nominal interest rates relative to history, high equity valuations, and the flow of assets into alternative asset classes. At the same time, colleges such as Bowdoin have become increasingly reliant on endowments in order to be able to offer admission to the best students, regardless of their financial situation, as well as compensation and research budgets to attract the best faculty in a highly competitive environment. Without the support of a growing endowment, this cost inflation would require significant tuition increases and quite possibly cuts to financial aid. The case offers students ample opportunities to examine the link between the financial needs of an investor ("liabilities") and its assets, and to analyze how this translates into effective investment risk management, liquidity management, return targets and the tradeoff between risk and return, and portfolio structuring decisions. The case also provides opportunities to examine performance evaluation as well as strategies for manager selection in an actively managed portfolio.

In April 2020, global financial markets were still reeling as the COVID-19 pandemic spread rapidly across the world. Global equity markets had initially fallen by 30% in response to the pandemic, and high-yield credit markets had dropped by nearly 20%. In contrast, U.S. Treasury markets were up 20% year-to-date (YTD). Interestingly, the U.S. Mortgage Backed Security (MBS) market had been much less responsive to the health crisis, exhibiting very low volatility throughout this period and returning about 2% YTD. Maya Russell, head of asset allocation research at a large global institutional investor, must make a recommendation on whether her fund's board should invest in MBS, and if so, whether this is a good time for the fund to implement the allocation and whether it should do so pursuing an active or a passive investment approach. This case covers a wide range of topics in fixed-income investing, including duration and interest rate risk, prepayment risk, mortgage securitization, and the design of mortgage-backed securities. These concepts are analyzed from the perspectives of both individual and professional investors in fixed-income and mortgage markets.

In June 2009, Sichuan Tengzhong Heavy Industrial Machinery Company Limited ("Tengzhong"), a little-known manufacturer of construction machinery and special-use vehicles in south-western China, took the global auto industry by surprise when it announced its plan to acquire the money-losing Hummer division of General Motors Corp. Hummer's premium sport-utility vehicles and sport-utility trucks had relatively low fuel efficiency of 9−16 miles per gallon. Since 2006, Hummer's sales volume had declined sharply due to escalating oil prices, its negative image as a "gas-guzzler" and a shift in customer preferences towards smaller sedans. Tengzhong had no prior experience in the light vehicle industry or in managing a major auto brand. Because this was Tengzhong's first attempt at foreign direct investment, it was imperative for its management to figure out the major obstacles in managing its new Hummer subsidiary in the US. They also had to formulate a sound business plan to get the Chinese government's approval for this acquisition, and to make the investment a big success. (Note: This acquisition was called off in February 2010 because Tengzhong was not able to get the Chinese government's approval. The details are included in Appendix 1 of the teaching note for reference.)

A capital-intensive industry that requires sophisticated high technology and enormous economies of scale, the global large civil aircraft industry allows only a few profitable players and has been dominated by the duopoly of The Boeing Company ("Boeing") and Airbus S.A.S. ("Airbus"). Although outsourcing has been evident since the 1970s, since the 1990s, Boeing and Airbus have become increasingly reliant on foreign suppliers, especially those in newly emerging markets, such as China. Industrial offset arrangements allow the two giants to contract their production processes, and increasingly the actual design and engineering work, to Chinese suppliers in exchange for guaranteed sales of the finished aircraft to Chinese airlines. This case provides a brief introduction to the global large civil aircraft industry. It can be used to teach courses with a focus on economics, business management, production and operational management.

This case illustrates China's attempts at building its own regional jets and large civil aircraft. The case can be used to teach courses in international competitiveness and strategic management at the country, industry or firm level. It can also be used as an introduction to corporate mission and governance issues for companies that are dominated by government shareholders.
