|2016–17 Slovenian Basketball League|
The Premier A Slovenian Basketball League (Slovene: 1. Slovenska Košarkarska Liga), abbreviated as 1. SKL and known as the Liga Nova KBM due to sponsorship reasons , is the top-level professional men's basketball league in Slovenia. The league, operated by the Basketball Federation of Slovenia, consists of 12 clubs. It was also named Liga Kolinska (1998–2001), HYPO Liga (2001–2002), 1. A SKL (2002–2006), Liga UPC Telemach (2006–2009), and Liga Telemach (2009–2016). The most successful team is Olimpija with 15 titles.
The league was founded in 1991, shortly after Slovenia gained its independence from SFR Yugoslavia. Before the independence, the Slovenian Republic League was played as a second or third level of the Yugoslav basketball. Olimpija, Ljubljana, Slovan, ŽKK Maribor, Lesonit and Branik Maribor were the only Slovenian teams that played in the Yugoslav First Federal Basketball League.
The league is conducted in two phases.
In the first phase, 12 teams compete in a home-and-away round-robin series (22 games total) with the country's representative in the Adriatic League, currently Olimpija and Krka, being exempt from this stage.
All teams advance from the regular season to one of two postseason stages, depending on their league position.
The top seven teams from the regular season are joined by the Adriatic League representative in the second phase. These teams start the second phase from scratch, with no results carrying over from the regular season. Each team plays a total of 14 games in this phase; as in the regular season, a home-and-away round-robin is used.
The top four teams at the end of this stage advance to the semifinals, conducted as a best-of-three playoff. The semifinal winners advance to the best-of-five championship finals, with the winners being crowned league champion.
The bottom five teams play a home-and-away round-robin series with one another; these teams' results from the regular season carry over to the playouts. At the end of the playout phase, the bottom finisher is automatically relegated to the second level of the Slovenian league system, the 2. SKL. That team is replaced in the following season's league by the 2. SKL champion. The second-from-bottom finisher enters a home-and-away round-robin mini-league with the second- and third-place teams from the second league, with the team finishing on top of the mini-league taking up a place in the next year's 1. A SKL.
