1 Portfolo Loss Dstrbuton
2 Rsky assets n loan ortfolo hghly llqud assets holdtomaturty n the bank s balance sheet Outstandngs The orton of the bank asset that has already been extended to borrowers. Commtment A commtment s an amount the bank has commtted to lend. Should the borrower encounter fnancal dffcultes, t would draw on ths commtted lne of credt.
3 Adjusted exosure and exected loss Let α be the amount of drawn down or usage gven default. Outstandng + α commtment, Rsky Asset value at later tme H, V H Adjusted exosure s the rsky art of V H.

Assumtons * The random rsk factors contrbutng to an oblgor s default (resultng n EDF) are statstcally ndeendent of the severty of loss (as gven by LGD). * The default rocess s twostate event.

7 Comarson between exected loss and unexected loss * The hgher the recovery rate (lower LGD), the lower s the ercentage loss for both EL and. * EL ncreases lnearly wth decreasng credt qualty (wth ncreasng EDF) * ncreases much faster than EL wth ncreasng EDF. Percentage loss er unt of adjusted loss 10% 5% 10% EL EDF
8 Assets wth varyng terms of maturty * The longer the term to maturty, the greater the varaton n asset value due to changes n credt qualty. * The twostate default rocess aradgm nherently gnores the credt losses assocated wth defaults that occur beyond the analyss horzon. * To mtgate some of the maturty effect, banks commonly adjust a rsky asset s nternal credt class ratng n accordance wth ts terms to maturty.
9 Portfolo exected loss where EL EL AE LGD EDF EL s the exected loss for the ortfolo, AE s the rsky orton of the termnal value of the th asset to whch the bank s exosed n the event of default. We may wrte EL AE w EL AE where the weghts refer to AE w AE AE AE.

12 Rsk contrbuton The rsk contrbuton of a rsky asset to the ortfolo unexected loss s defned to be the ncremental rsk that the exosure of a sngle asset contrbutes to the ortfolo s total rsk. RC and t can be shown that RC j j ρ j.
13 Undversfable rsk The rsk contrbuton s a measure of the undversfable rsk of an asset n the ortfolo the amount of credt rsk whch cannot be dversfed away by lacng the asset n the ortfolo. RC To ncororate ndustry correlaton, usng ndustry α and j ndustry β RC (1 ) + α ραα β α k β k ρ αβ.

15 Fttng of loss dstrbuton The two statstcal measures about the credt ortfolo are ortfolo exected loss; ortfolo unexected loss. At the smlest level, the beta dstrbuton may be chosen to ft the ortfolo loss dstrbuton. Reservaton A beta dstrbuton wth only two degrees of freedom s erhas nsuffcent to gve an adequate descrton of the tal events n the loss dstrbuton.

Perform a decomoston (Cholesky, SVD or egenvalue) on the asset correlaton matrx to transform the ndeendent set of random numbers (stored n the vector e ) nto a set of correlated asset values (stored n the vector e ). Here, the transformaton matrx s M, where e M e. The covarance matrx and M are related by M T M.

27 Features of ortfolo rsk The varablty of default rsk wthn a ortfolo s substantal. The correlaton between default rsks s generally low. The default rsk tself s dynamc and subject to large fluctuatons. Default rsks can be effectvely managed through dversfcaton. Wthn a welldversfed ortfolo, the loss behavor s characterzed by lower than exected default credt losses for much of the tme, but very large losses whch are ncurred nfrequently.
