Last week, Lands’ End, Inc. (NASDAQ: LE) announced that it would write down the value of its flagship trade name asset (Lands’ End). Management’s preliminary guidance is for a charge of $90 million to $110 million, which could lower the asset’s value by 20% from $528 million to $418 million. Obviously, a non-cash impairment charge is just that, non-cash, but what does it mean for stakeholders and how is such a charge actually determined?
