Exposure at Default (EAD) represents the total value that a bank or financial institution is exposed to at the time of a borrower’s default. In essence, it estimates the amount of credit risk the lender faces upon the event of default. Understanding and calculating EAD correctly is vital for effective risk management and regulatory compliance.
Significance of Exposure at Default (EAD)
Role in Risk Management
EAD is a critical component in the quantification of credit risk. Banks utilize EAD to determine the potential financial loss if a borrower defaults on their loan. This helps in setting aside sufficient capital reserves to cover unexpected losses.
Regulatory Compliance
EAD is also essential for regulatory purposes. Regulatory frameworks like Basel II and Basel III require banks to compute EAD for calculating their capital requirements. Accurately determining EAD ensures that banks remain solvent and maintain financial stability.
Calculation Methods for Exposure at Default (EAD)
Standardized Approach
The standardized approach entails using fixed risk weights or parameters set by regulatory bodies. This method is straightforward but lacks customization for specific loan products or borrower profiles.
Internal Ratings-Based Approach (IRB)
Banks using the Internal Ratings-Based (IRB) approach rely on internal models to estimate EAD. This method offers more precision and customization, considering factors such as loan type, repayment structure, and borrower’s credit history.
Foundation IRB
The Foundation IRB approach allows banks to use their internal rating systems to determine the probability of default (PD) and loss given default (LGD), but EAD must be calculated using standardized methods.
Advanced IRB
The Advanced IRB approach provides banks with the flexibility to use their internal models for calculating PD, LGD, and EAD, enhancing the accuracy and relevancy of risk estimates.
Special Considerations
Off-Balance Sheet Items
EAD calculations must account for off-balance sheet exposures such as letters of credit, guarantees, and undrawn credit lines. These items can significantly affect the total exposure at default.
Collateral and Guarantees
The presence of collateral and guarantees can mitigate the risk to some extent. Therefore, these factors are considered during the EAD calculation process.
Examples
Example 1: Loan with Fixed Repayment
Consider a bank that has issued a $1,000,000 loan with a fixed repayment schedule. If the borrower defaults with an outstanding balance of $800,000, the EAD is $800,000.
Example 2: Revolving Credit Facility
In the case of a revolving credit facility with a credit limit of $500,000 and current outstanding of $300,000, the EAD can be higher than the current exposure due to potential future drawdowns.
Historical Context
Evolution of Credit Risk Management
The concept of EAD has evolved alongside the development of modern financial systems. Prior to regulatory frameworks like Basel, banks often lacked standardized methods for assessing credit exposure. The introduction of Basel II and later Basel III significantly advanced the accuracy and consistency of credit risk management practices, emphasizing the importance of EAD.

- Probability of Default (PD): PD is the likelihood that a borrower will default on a loan within a given time frame. It is a key input in the calculation of expected credit loss.
- Loss Given Default (LGD): LGD represents the portion of the exposure that is expected to be lost if the borrower defaults, after accounting for any recoveries from collateral or guarantees.

Summary
Exposure at Default (EAD) represents the total risk a bank faces when a borrower defaults on a loan. Essential for both effective risk management and regulatory compliance, EAD calculations consider on and off-balance sheet exposures, collateral, guarantees, and the type of loan product. By understanding EAD, banks can establish adequate capital reserves and maintain financial stability.
