问题如下:
Which comment regarding CDOs and covered bonds is accurate?
选项:
A. Easton’s comment
B. Avelyn’s first comment
C. Avelyn’s second comment
解释:
A is correct.
CDOs typically include some form of subordination. With subordination, a CDO has more than one bond class or tranche, including senior bond classes, mezzanine bond classes (which have credit ratings between senior and subordinated bond classes), and subordinated bond classes (often referred to as residual or equity tranches).
The correlation of expected defaults on a CDO’s collateral affects the relative value between the senior and subordinated tranches of the CDO.
As correlations increase, the values of the equity tranches usually increase relative to the
values of the senior and mezzanine tranches
是否可以这样理解: 当senior tranche 和subordinated tranche 的违约相关系数较低时, 资产池内动不动就有人违约; 而当其相关系数较高时, 资产池内要么同时违约, 要么同时不违约. 相较前者, 在后者情况下, equity tranche 有更高的概率不违约, 所以其相对价值会升高. 谢谢.
