Shows produced by not-for-profits like Roundabout, MTC and Lincoln Center, by definition cannot flop or be a hit. They don't have investors to pay back (they're financed by a combination of private and government donations and ticket sales), so they thus, cannot "recoup." "Hit" and "flop" are terms that ONLY apply to purely commercial shows.
Thus, ASSASSINS (both the original and revival), the PACIFIC OVERTURES revival, BERNARDA ALBA, FLOYD COLLINS, BRIGHT LIGHTS, BIG CITY should be left out of this discussion.
And yes, BROOKLYN is considered a flop for Broadway since it did not recoup during its engagement here.
