  1. Texas Teachers and the New Texas Way

    Matthew Rhodes-Kropf, Luis M. Viceira, John D. Dionne and Nathaniel Burbank

    In 2011 Britt Harris, the Chief Investment Officer for the $107.4 billion Teachers Retirement System of Texas (TRS), was considering whether to pursue strategic partnerships with a group of large private equity firms. After spending four years aggressively moving the fifth largest pension fund in the United States into alternative asset classes, Harris felt that TRS shouldn't just participate in private equity funds as a typical limited partner. Rather, under his proposal TRS would offer carefully vetted firms multi-billion dollar investments through a customized fund structure that had fewer allocation mandates than traditional fund structures, and guarantees to reinvest 50% of any investment gains back into the investment vehicle. In exchange, Harris hoped to receive a highly customized compensation structure and gain greater access to investment professionals within the participating firms.

  2. Blackstone at Age 30

    Josh Lerner, John D. Dionne and Amram Migdal

    Since its IPO in 2007 and following the global financial crisis, Blackstone largely outpaced its alternative investment firm peers in assets under management, new business launches, profitability, and market capitalization. Under the leadership of Stephen A. Schwarzman, chairman and CEO, and president and COO Hamilton ("Tony") James, Blackstone's growth derived from substantial horizontal expansion into new alternative asset products and services, both organically and through acquisition. These included businesses in private equity, real estate, funds of hedge funds, alternative credit, opportunistic transactions ("Tactical Opportunities"), and secondaries investments. The firm has also innovated in sourcing capital from a variety of limited partners. Blackstone's culture of centralized investment processes and risk management coupled with entrepreneurial leadership contributed to its growth in important ways, but the firm faces important external and internal challenges as it seeks to continue its growth.

  3. Eastman Kodak Company: Restructuring a Melting Ice Cube

    Stuart C. Gilson, John D. Dionne and Sarah L. Abbott

    In May 2013, senior managers of GSO Capital Partners, an $80 billion credit-oriented investment firm owned by The Blackstone Group, are considering what to do next with their investment in the senior secured debt of Eastman Kodak Company. Once a great company and an icon of American business, Kodak had fallen on desperately hard economic times as its traditional business of manufacturing cameras and photographic film had all but disappeared with the rise of digital photography, causing its annual revenues to plummet from $13 billion to $6 billion, and its stock price to fall by 95%, between 2003 and 2011. Having taken various positions in Kodak's debt during the previous four years, GSO is now faced with a major decision. Under the company's recently proposed plan of reorganization, secured creditors were to be given 85% of the company's common stock, but unsecured creditors objected to the plan. Now, six months later, GSO has brought an amended plan to the table under which it would commit to backstop a $406 million equity rights offering that would be made directly to all the unsecured creditors. This offer might bring the objecting creditors on board but could also require an additional large capital commitment by GSO, which was already heavily invested in a highly troubled business that many viewed as a "melting ice cube."
