这道题的C也不对吧，shortfall损失由support tranche提供？

十分位和百分位是什么意思？

Debt covenants are least likely to place restrictions on the issuer's ability to: A pay dividends. B issue additional debt. C issue additional equity. 我怎么觉得a这种能力也不会限制？

老师 不理解A和C选项 这里的pass through 和 transform应该怎么理解呢？

请问进阶题目的讲解在哪里看？

老师您好 这里有两个问题：1， 这幅图的第20题:想请问 Depre expense 在Unit-on-production时 都是采用的全体年份 而非当年的total生产量对吧，全体年份是否应从2009.1-expiration date? 2. 我在不同的地方看到过book value，比如计算ROE时，CFI计算时也会book value=carrying value-Depre-impairment loss，目前只想到这两处 想问下这两个book value说的是一个意思么

那么sharpe ratio和大盘比，高了好还是低了好呢？
