The term Advanced IRB or A-IRB is an abbreviation of advanced internal ratings-based approach, and it refers to a set of credit risk measurement techniques proposed under Basel II capital adequacy rules for banking institutions. Under this approach the banks are allowed to develop their own empirical model to quantify required capital for ...
IRB stands for "Internal Rating-Based Approach". For operational risk, there are three different approaches – basic indicator approach or BIA, standardized approach or TSA, and the internal measurement approach (an advanced form of which is the advanced measurement approach or AMA). For market risk the preferred approach is VaR (value at risk).
Movements in LGD often result in proportional movements in required economic capital. According to BIS (2006) institutions implementing Advanced-IRB instead of Foundation-IRB will experience larger decreases in Tier 1 capital, and the internal calculation of LGD is a factor separating the two Methods.

There are some options in weighing risks for some claims, below are the summary as it might be likely to be implemented. NOTE: For some "unrated" risk weights, banks are encouraged to use their own internal-ratings system based on Foundation IRB and Advanced IRB in Internal-Ratings Based approach with a set of formulae provided by the Basel-II accord.
Under A-IRB, the bank itself determines how the appropriate EAD is to be applied to each exposure. A bank using internal EAD estimates for capital purposes might be able to differentiate EAD values on the basis of a wider set of transaction characteristics (e.g. product type) as well as borrower characteristics.
