Please answer a question about the following article about American Idol:

The winner receives a record deal with a major label, which may be for up to six albums, and secures a management contract with American Idol-affiliated 19 Management (which has the right of first refusal to sign all contestants), as well as various lucrative contracts. All winners prior to season nine reportedly earned at least $1 million in their first year as winner. All the runners-up of the first ten seasons, as well as some of other finalists, have also received record deals with major labels. However, starting in season 11, the runner-up may only be guaranteed a single-only deal. BMG/Sony (seasons 1–9) and UMG (season 10–) had the right of first refusal to sign contestants for three months after the season's finale. Starting in the fourteenth season, the winner was signed with Big Machine Records. Prominent music mogul Clive Davis also produced some of the selected contestants' albums, such as Kelly Clarkson, Clay Aiken, Fantasia Barrino and Diana DeGarmo. All top 10 (11 in seasons 10 and 12) finalists earn the privilege of going on a tour, where the participants may each earn a six-figure sum.

The winner also receives a management contract with which company?
19 Management
