A Non-parametric Approach to Incorporating Incomplete Workouts Into Loss Given Default Estimates [PDF]

When estimating Loss Given Default (LGD) parameters using a workout approach, i.e. discounting cash flows over the workout period, the problem arises of how to take into account partial recoveries from incomplete work-outs.
