Exposure at default (EAD) is the total value a bank is exposed to when a loan defaults. Financial in🐼stitutions calculate their risk using the internal ratings-based (IRB) approach. Banks often use internal risk management default models to estimate their respective EAD systems. Outside of the banking industry, EAD is known as credit exposure.

Understanding Exposure at Default

EAD is the predicted amount of▨ loss a bank may be exposed to when a debtor defaults on a loan. Banks often calculate an EAD value for each loan and then use these figures to determine their overall default risk. EAD is a dynamic number that changes as a borrower repays a lender.

There are two methods to d෴etermine exposure at default. Regulators use the firꦡst approach, which is called foundation internal ratings-based (F-IRB). This approach to determining exposure at risk includes forward valuations and commitment detail, though it omits the value of any guarantees, collateral, or security.

The second method, 澳洲幸运5官方开奖结果体彩网:advanced interꦬnal 𒈔ratings-based (A-IRB), is more flexible and is used by banking institutions. Banks must disclose their risk exposure. A bank will base this figure on data and internal analysis, such as borrower characteristics and product type. EAD, along with 澳洲幸运5官方开奖结果体彩网:loss given default (LGD) and 澳洲幸运5官方开奖结果体彩网:the probability of default (PD), are used to calculate the credit risk capital of financial institutions.

Special Considerations

The Probability of Default and Loss Give♔n Default

PD analysis is a method larger institutions use to calculate their expected 𒁏loss. A PD is assigned to each risk measure and represents, as a percentage, the likelihood of default. A PD is typically measured by assessing past-due loans. It is calculated by running a migration analysis of similarly rated loans. The calculation is for a specific time frame and measures the percentage of loans that default. The PD is then assigned to the risk level, and each risk level has one PD percentage.

LGD, unique to the banking industry or segment, measures the expected loss. It's shown as a percentage. LGD represents the amount unrecovered by the lender after selling the underlying asset if a borrower defaults on a loan. Determining an accurate LGD variable may be difficult if portfolio losses differ from expectations. An inaccurate LGD may also be due to the segment being statistically small. Industry LGDs are typically available from third-party lenders.

Also, PD and LGD numbers are usually valid throughout an economic cycle. However, lenders🌄 will reevalꦬuate when changes to the market or portfolio composition occur. Changes that may trigger reevaluation include economic recovery, recession, and mergers.

A bank may calculate its expected loss by multiplying the variable 🍨EAD by the PD and the LGD:

EAD x PD x LGD = Expected Loss

Exposure at Risk Example

Modern economies 𝔍have become increasingly intertwined. What happens in one country is more likely to financially impact others, especially when a wide-scale calamity is experienced.

Consider the impact of Lehman Brothers' bankruptcy filing in 2008. Subprime mortgage loans heightened the company's exposure to default, and Lehman Brothers' credit rating was downgraded, forcing the Federal Reserve to summon several banks to negotiate financing for its reorganization. Congress also passed a $700 billion rescue bill in response to the widespread financial risk the firm's collapse could have.

In response to the credit crisis of 2007–2008, the banking sector adopted international regulations to lessen its exposure to default. The Basel Committee on Banking Supervision aims to improve the banking sector's ability to deal with financial stress. The intꦆernational accord hopes to avoid the domino effect of failing financial institutions by improving risk management and bank transparency.

The Bottom Line

Lending is an inherently risky undertaking. Banking institutions use metrics like EAD to make wise choices about who they lend to, since they ultimately must answer to their investors. Credit exposure is an issue in most industries, and EAD is one of the banking world's primary tools to combat loan loss.
