Since individual salaries are negotiated before the season starts (in many cases years before), and BRI is not determined until the season concludes, there are mechanisms in place to adjust when salaries miss their target. If the players receive less than their guaranteed share of BRI, the league cuts a check to the players association for the difference, and this amount is distributed to the players (this happened in 2014-15, 2015-16, and 2016-17, under the 2011 CBA). The escrow system adjusts the players' salaries when they earn more than their guaranteed share (see question number 16). An additional benefits pool is funded with 1% of BRI, which comes out of the players' share. This pool is used to fund various benefits and annuities for players who have vested. If there is an escrow overage (see question number 16) and the escrow fund is not large enough to bring salaries and benefits down to the players' designated share, they take the remainder out of this pool.
