B) Exposure × Loss given default × (1 ? Probability of default).

C) Exposure × (1 ? Recovery rate) × Probability of default.

D) Exposure × (1 ? Loss given default) × (1 ? Probability of default).

C) Expected loss is less important than unexpected loss in determining capital adequacy levels.

D) Expected loss is more important than unexpected loss in determining capital adequacy levels.

The correct answer is C

Unexpected loss is more important in determining capital adequacy levels since the bank needs to stay solvent during the infrequent periods where actual losses deviate significantly from expected losses.

A) expected losses matching actual losses.

B) expected losses exceeding actual losses.

C) actual losses exceeding expected losses.

AIM 5: Define exposures, adjusted exposures, commitments, covenants, and outstandings.

1、Bank X has contractually agreed to a $20,000,000 credit facility with Bank Y. Y will immediately access 40% of the commitment. Bank X has no experience with Bank Y and conservatively estimates drawdown in default to be 75%. Calculate the adjusted exposure for Bank X.

A) $12,000,000.

B) $8,000,000.

C) $15,000,000.

D) $17,000,000.

aianjie

 

The correct answer is D

Adjusted exposure  = OS + (COM ? OS) × UGD 

  = $8,000,000 + ($12,000,000) × (0.75) 

  = $17,000,000
