请问为什么最安全的不是mortgage bond，以房产作为抵押的不是应该比机器设备做抵押更有保障吗

Senior bentures. A is correct. ETCs, or equipment trust certificates, are generally the most secure because the unrlying assets are actually ownethe trustee anrenteto the borrower. Also, the assets are usually stanrzefor easy resale.解析哪一个债券的利息最低？有抵押品的债券利息最低，在所有有抵押品的债券里，ETC的抵押品质量最好，利息最低。 1、“Equipment trust certificates”老师好，以机器设备抵押的债券，是指债券发行人用设备所有权做抵押发行的债券？之前有一道题，提到A将设备卖给B，B将设备回租给借款人，借款人还清借款时就拥有了设备所有权。这过程不就是售后回租吗？和设备抵押债券有什么关系呢？2、“Mortgage bon”是以房地产贷款为抵押的债券？
