Where This Unit Fits
This unit continues Layer 2 by moving from consumer receivables and mortgage-backed products into leveraged loan securitization. After studying ABS, MBS, and CMBS, students now examine CLOs, which are among the most important structured finance products tied to corporate credit markets.
CLOs differ from many other securitizations because the underlying collateral consists largely of leveraged loans and the portfolio may be actively managed over time. This introduces a different operating model, one that combines structured securities, corporate credit exposure, manager discretion, coverage tests, and ongoing investor surveillance.
Unit Overview
Collateralized loan obligations pool leveraged loans and issue multiple classes of securities backed by the cash flows of those loans. These structures divide risk across tranches with different payment priorities and rely on collateral managers to select, monitor, and often actively manage the loan portfolio within defined guidelines.
This unit introduces the core operating model of CLOs, including leveraged loan collateral pools, capital stack design, collateral manager responsibilities, coverage tests, cash flow waterfall logic, and investor reporting practices. Students learn how CLOs function as both structured credit products and actively monitored portfolios within institutional loan markets.
Why This Matters in Structured Finance
CLOs are central to modern leveraged finance because they connect institutional loan markets to securitization structures and investor demand. They provide funding for leveraged loans, create diversified credit exposures for investors, and support active portfolio management within a structured framework. Because CLOs depend on loan quality, manager performance, and structural protections, they require careful analysis across both collateral and transaction design.
Students who understand this unit are better prepared to explain how leveraged loan pools are securitized, why CLO capital structures differ across tranches, how coverage tests protect investors, and why collateral managers play such a critical role in portfolio construction, monitoring, and performance.
