Quoted from ForceFlow:

Most large-ish companies have a line item in their budget for legal expenses for "rainy day" scenarios. I wouldn't worry too much so long as it doesn't drag out for an extended period of time. I imagine the two companies will file a few motions back and forth, attending a hearing, and possibly get a preliminary ruling. It might end there, but if not, Then they may go back and forth some more, and either eventually drop the case, settle, or go to trial.

Quoted from 2RustyBalls:

Totally incorrect! As posted the accounting issues clearly hid the issues until an Audit most likely. 3 years is nothing. The Audit could have taken a year just to track down the issue. Elaut has made a very serious claim don't kid yourself. The tax issue a lone is huge, think about it.
