CDOs backed by corporate bonds and emerging market bonds are called Collateralized Bond Obligations (CBOs), whereas CDOs backed by ABS, RMBS, CMBS, and other CDOs are known as structured CDOs.<\/p>\n<h2><strong>CDO Structure<\/strong><\/h2>\n<p>A CDO involves the creation of a Special Purpose Entity (SPE). Then, the CDO manager (or collateral manager) buys and sells debt obligations for and from the CDO&#8217;s collateral to meet cash obligations to CDO bondholders.<\/p>\n<p>The source of funds to purchase the collateral assets is the issuance of debt obligations. Debt obligations are a variety of bonds or bond tranches, including senior, mezzanine, or subordinated (equity or junior) bond classes.<\/p>\n<p>A CDO is a leveraged transaction. As such, investors who buy the equity tranche use borrowed funds to generate a return higher than the funding costs.<\/p>\n<h4><strong>Example: CDO<\/strong><\/h4>\n<p>To illustrate the structure of a CDO transaction, the following is a $100 million CDO issue example:<\/p>\n<p>$$<br \/>\\begin{array}{l|c|c}<br \/>\\textbf{Tranche} &amp; \\textbf{Par value (US\\$)} &amp; \\textbf{Coupon rate} \\\\<br \/>\\hline<br \/>\\text{Senior} &amp; \\text{80,000,000} &amp; \\text{LIBOR + 50 bps} \\\\<br \/>\\text{Mezzanine} &amp; \\text{10,000,000} &amp; \\text{10-year US Treasury + 300bps} \\\\<br \/>\\text{Equity (junior)} &amp; \\text{10,000,000} &amp; \\text{} \\\\<br \/>\\end{array}<br \/>$$<\/p>\n<p>Assume that the 10-year US Treasury rate at the time this CDO is issued is 8%, and the coupon rate is the 10-year US Treasury rate + 500 bps.<\/p>\n<p>The collateral pays a fixed rate. However, the senior tranche requires a floating-rate payment.The CDO manager, therefore, enters into an interest rate swap agreement with another party with a notional amount of $80 million to:<\/p>\n<ul>\n<li>pay a fixed annual rate equal to the 10-year US Treasury + 200 bps; and<\/li>\n<li>receive LIBOR.<\/li>\n<\/ul>\n<p>Here is a table summarizing the cash inflows and outflows for each of the tranches in this CDO:<\/p>\n<p>$$<br \/>\\begin{array}{l|c|c}<br \/>\\text{Senior} &amp; \\begin{array}{c} \\text{Interest from swap} \\\\ \\text{= (8% + 5%) \u00d7 \\$100m =} \\\\ \\text{\\$13m} \\end{array} &amp; \\begin{array}{c} \\text{Interest to senior tranche} \\\\ \\text{= \\$80m \u00d7 (LIBOR + 50 bps) = \\$0.4m +} \\\\ \\text{\\$80m \u00d7 LIBOR} \\end{array} \\\\<br \/>\\hline<br \/>\\text{Mezzanine} &amp; \\begin{array}{c} \\text{Interest from swap} \\\\ \\text{counterparty} \\\\ \\text{= \\$80m \u00d7 LIBOR} \\end{array} &amp; \\begin{array}{c} \\text{Interest to mezzanine tranche} \\\\ \\text{= \\$10m \u00d7 (8% + 3%) = \\$1.1m} \\end{array} \\\\<br \/>\\hline<br \/>\\text{} &amp; \\text{} &amp; \\begin{array}{c} \\text{Interest to swap counterparty} \\\\ \\text{= \\$80 \u00d7 (8% + 2%) = \\$8m)} \\end{array} \\\\<br \/>\\hline<br \/>\\text{} &amp; \\begin{array}{c} \\text{Total: \\$13m + (\\$80m \u00d7} \\\\ \\text{LIBOR)} \\end{array} &amp; \\text{Total: \\$9.5m + (\\$80m \u00d7 LIBOR)} \\\\<br \/>\\hline<br \/>\\text{Equity (junior)} &amp; \\text{Net interest = \\$3.5m} &amp; \\text{} \\\\<br \/>\\end{array}<br \/>$$The amount available for distribution to the equity (junior) is whatever is left from the two other tranches less management fees.<\/p>\n<h2><strong>Risks Related to CDOs<\/strong><\/h2>\n<p>The risk of default and the risk of a decrease in the coupon rates are prevalent in CDOs. Also, there is always the risk that the manager will fail to earn a return sufficient to pay off the investors in the senior and mezzanine bond classes. In the equity tranche\u00a0\u2013 just like when buying equity in the stock markets\u00a0\u2013 there is the risk that the investor will lose their entire investment.<\/p>\n<blockquote>\n<h3><strong>Question<\/strong><\/h3>\n<p>Which of the following classes carries the highest level of risk?<\/p>\n<ol style=\"list-style-type: upper-alpha;\">\n<li data-tadv-p=\"keep\">Senior.<\/li>\n<li data-tadv-p=\"keep\">Mezzanine.<\/li>\n<li data-tadv-p=\"keep\">Subordinated.<\/li>\n<\/ol>\n<p><strong>Solution<\/strong><\/p>\n<p>The correct answer is <strong>C<\/strong>.<\/p>\n<p>Subordinated (also called junior or equity) bond classes are residual tranches.
