Overview
Fifth Street Asset Management Inc. was a U.S. alternative asset manager focused on credit investments and lending to small and medium-sized businesses. The businesses targeted by its lending activities generally generated annual revenue of approximately $25 million to $500 million. Rather than operating primarily as a traditional retail investment-management brand, Fifth Street built its business around the management of business development companies, private investment vehicles, senior-loan funds, and related credit strategies. The firm was founded in 1998 by Leonard M. Tannenbaum. Its principal investment platform included Fifth Street Finance Corporation and Fifth Street Senior Floating Rate Corporation, two publicly traded business development companies. Fifth Street Finance was established in 1998 and completed its initial public offering in 2008. Fifth Street Senior Floating Rate was formed in 2013. Through these vehicles and other funds, the manager provided loans and other financing to smaller companies, a segment that is often underserved by large commercial banks but offers specialized credit managers opportunities to earn management and incentive fees. Fifth Street expanded its platform through partnerships and structured financing arrangements. In 2014, Fifth Street Finance partnered with Kemper Corporation on two joint ventures involving stated equity commitments of $200 million and leverage of $400 million. The arrangements were designed to expand lending capacity and distribute additional debt exposure. The firm also managed two senior-loan funds and maintained a broader institutional credit business. By the middle of the 2010s, Fifth Street reported more than $6 billion in assets under management across its two public business development companies and multiple private investment vehicles. Its principal offices were identified in Greenwich, Silicon Valley, Dallas, and Chicago, and the organization had more than 100 professionals. Its business model generated revenue primarily from management fees and related fees associated with the assets and investment portfolios it managed. For the quarter ended March 31, 2015, reported total revenue was $24.9 million, with management fees accounting for most of the total; these figures are historical and should not be treated as current financial information. Fifth Street also became a public company in its own right. After initially withdrawing a proposed offering, it amended and completed an initial public offering in October 2014 under the NASDAQ ticker FSAM. The offering was reduced from the originally proposed size, and the shares experienced a sharp decline during their first trading day. The company and its investment vehicles subsequently faced investor criticism over equity issuances that were viewed as dilutive, including offerings by the business development companies at prices below previously reported net asset value. The Fifth Street platform ultimately underwent a major transition in 2017. On July 14, 2017, Oaktree Capital Management announced that it would assume management of Fifth Street Finance Corporation and Fifth Street Senior Floating Rate Corporation. The transaction closed on October 17, 2017. Following the closing, the two funds were renamed Oaktree Specialty Lending Corporation and Oaktree Strategic Income Corporation, respectively. This change ended Fifth Street's role as manager of its principal publicly traded business development companies and marked the effective end of the Fifth Street asset-management platform as described in the cited historical sources.
History
Fifth Street Asset Management was founded in 1998 by Leonard M. Tannenbaum as a credit-focused investment manager serving the U.S. middle market. Its strategy centered on lending to smaller companies, generally businesses with annual revenue between $25 million and $500 million. The firm developed a platform combining publicly traded business development companies, private investment funds, senior-loan funds, and joint ventures. The first major public vehicle associated with the platform was Fifth Street Finance Corporation, founded in 1998 and taken public in 2008. A second public business development company, Fifth Street Senior Floating Rate Corporation, was established in 2013. These vehicles invested in loans and other credit instruments issued by middle-market companies, allowing Fifth Street to earn management fees and related compensation while providing capital to borrowers that might not have had the same access to traditional bank financing. In 2014, Fifth Street Finance entered into two joint ventures with Kemper Corporation. The arrangements were described as having $200 million of equity commitments and $400 million of leverage, giving the partners additional capacity for lending activities. Fifth Street also maintained two senior-loan funds and several private investment vehicles. During this period, the firm reported more than $6 billion of assets under management across its two public business development companies and private funds, with principal offices in Greenwich, Silicon Valley, Dallas, and Chicago and a workforce of more than 100 professionals. Fifth Street Asset Management became publicly traded in October 2014. It had initially withdrawn its proposed offering before filing an amended version that reduced the size of the IPO. The shares began trading on NASDAQ under FSAM, but the stock fell materially during its first trading session. The firm and its managed investment companies also attracted negative investor attention in 2014 after issuing new shares. Critics argued that certain offerings were dilutive to existing shareholders, particularly where shares were issued below a previously reported net asset value. Historical company reporting cited in the reference material showed that total revenue for the quarter ended March 31, 2015, was $24.9 million, compared with $23.8 million for the corresponding quarter a year earlier. Management fees represented the large majority of quarterly revenue, and fee-earning assets under management had increased year over year. These results illustrate the fee-based economics of the platform but are not current figures. The decisive change came in 2017. Oaktree Capital Management announced on July 14 that it would assume management of Fifth Street Finance Corporation and Fifth Street Senior Floating Rate Corporation. The transaction closed on October 17. Oaktree renamed the funds Oaktree Specialty Lending Corporation and Oaktree Strategic Income Corporation. Because those two public business development companies were the core of Fifth Street's operating platform, the transaction effectively ended Fifth Street's role as their investment manager and marks the end of the brand's active historical business as documented by the cited sources.
