So far, this book has been largely concerned with credit exposure. Now we aim to describe the default component in more detail. We discuss the nature of default probability, recovery rates and associated credit spreads. The focus will be largely on corporate entities, which are most relevant from the point of view of counterparty risk. We will also review the range of credit derivatives products, which will be discussed in some later chapters. Hence, this chapter is a review of all the key credit risk and credit derivatives aspects and may be skipped by the reader experienced in these areas. However, many subtle questions can only be answered from a detailed knowledge of credit risk and credit derivatives products. For example:
Suppose an institution has an uncollateralised credit exposure of $10m to a defaulted counterparty but they also have $10m of credit default swap protection against the counterparty in question. Is this a perfect hedge?
