The salary cap between the 1999 and 2005 CBA versions has not changed much. In exchange for approving the controversial minimum age of players, players received a slightly higher percentage of the league`s revenue during the new convention. In addition, the league`s maximum score decreased slightly from the 1999 CBA. Under the 2011 CBA, players received a lower percentage of the league`s revenues. A two-way contract is the contract between a two-way player and an NBA team that pays him a two-way salary. A two-way contract is defined primarily by what it cannot do and who cannot sign: to tackle this problem, the CBAs have, since at least the 1990s, included the so-called “over 38” rule, according to which certain contracts exceeding the player`s 38th birthday should cover the seasons after the expected departure of the player. The age limit that triggered this rule was initially set at 35, 36 in CBA in 1999 and 38 in CBA in 2017. The salary for all years following the player`s 38th birthday is considered a deferred allowance and deferred to the under-38s of the agreement for cape age, with persons over 38 being referred to as “zero years” in the CBA. If the player continues to play under the deal (which does not prove the presumption of departure), the salary that was initially considered deferred will be evenly distributed over the remaining years of the contract, starting with the second season before zero years. This rule was a more important topic prior to KBA 2011, which limited the maximum term of the contract to 5 years.  In 2005, players received 57% of revenues, and from the new CBA, they receive about 49 to 51% of the turnover.  At that time, the next debate on the CBA was set at ten years. or, if necessary, in 2017.
 In 2016, the NBA and nba Players Association met to work on a new CBA approved by both parties in December of that year. This last contract started with the 2017/18 season and runs until 2023/24, with a reciprocal opt-out after 2022/23.   In December 2016, the League and the Players` Union tentatively agreed on a new CBA that both sides will ratify before the end of the month.  The new contract runs until the 2023/24 season, with both parties able to withdraw after the 2022/23 season.  The salary cap in the NBA is the limit on the total amount of money that National Basketball Association teams can pay to their players. Like many professional sports leagues, the NBA has a salary cap to control costs and profit parity, defined by the League`s collective bargaining agreement (CBA). This limit is subject to a complex system of rules and exceptions and is calculated as a percentage of the league`s revenue from the previous season. Under the CBA ratified in July 2017, the cap will continue to vary based on league revenues over the coming seasons. For the 2019/20 season, the cap is set at $109.14 million.  According to ESPN, the NBA and the players` union have agreed on a new collective bargaining agreement.
