"How it worked under the old owners was this: store's lease is up. If a deal can't be reached with the landlord or sales are just so bad it's not worth it, the store will close on a set date."
Well said, and as I recall, totally true. BN never closed a store until the lease was over, at least in the old days. I assume they did this since, as they were a public company, they didn't want it getting around the Street saying that they were breaking leases with landlords, as this could negatively effect the stock price or scare away the money guys they needed to lend them cash.
Now that they are owned by a hedge fund–which probably means the new owners don't care a lot about literature and so forth–I have no idea if this will continue as a normal practice. If it's sheer dollars and cents, they may well break leases with abandon, and take what comes from the following lawsuits. If they plan on gutting the company for its breakup value, I honestly don't know what that value is; as most (if not all) locations are leased, there's not much real estate value, particularly since B&M retail isn't exactly thriving.
The best of luck for those still at BN. Those of us who have moved on since Black Monday (in my case, for a better and less stressful job) have been telling you to jump ship for quite some time now. Hopefully, those still manning the ramparts will realize the cause is lost.
