关于LGD的考虑

NO.PZ2023040701000093

问题如下:

Cromwell works with another analyst, George Hastings, to discuss credit scoring and credit rating models. Hastings starts the conversation by saying, “Credit scoring models are primarily applied to consumers or small business borrowers. In some cases, only negative information, such as delinquencies or defaults, are used, while other models use a mix of factors, such as payment history and recent credit searches.” The focus of credit scores is the probability of default. Hastings continues, “Credit ratings, on the other hand, are used in the corporate and sovereign bond market and also for asset-backed securities. Ratings are focused on probability of default. Credit rating agencies, such as Standard & Poor’s, consider the loss given default by means of notching, which adjusts the issuer rating to reflect the priority of claims in the capital structure."

Are Hastings’s comments regarding credit scores and credit ratings most likely correct?

选项:

A.

Yes

B.

No, he is incorrect with regard to credit scores.

C.

No, he is incorrect with regard to credit ratings.

解释:

Correct Answer: A

Hastings’s comments regarding both credit scores and credit ratings are correct.

老师,您好!

关于LGD的考虑,应该是基于公司的资产状况、债券抵押物的质量等因素吧,notching只是同一个issuer的不同债项的评级调整,能用来定义LGD(损失比例)吗?麻烦老师解释一下,谢谢!

嗨,爱思考的PZer你好:


这里原理是这样的:

notching是公司债项针对主体评级的调整,这个调整主要就是基于债权受偿顺序、是否有抵质押物等因素来进行的,评级公司综合考虑因素后给出评级结果,同时,评级公司也会一起给出每个评级的POD与LGD,我们作为投资者,观察到的就是评级公司的评级结果和对应的LGD、POD,并依次来对单笔债权定价。


这句话的意思也是说评级公司根据评级来定义LGD,所以这是没问题的。
