Swansea City have announced a record profit or the six months up to the end of November 2012.
The £15.9million profit announced by the club on Tuesday is almost £10million more than for the same period in 2011.
The Swans returned a profit of £14.6million for their first season in the Premier League.
The profit before tax of £20.4million was made up of a £5.6million profit from operations, while a further £14.8million came from player sales, including those of Joe Allen to Liverpool and Scott Sinclair to Manchester City.
Turnover, with the exclusion of player sales, has also risen to £28.5million, a growth of 11.5 per cent from the £25.5million for the previous six months.
Finance Director Don Keefe said: "The funds generated by the profit are invaluable bearing in mind the extent of finance needed, not only to maintain Premier League status, but for the expansion of capacity in the Liberty Stadium and the development of appropriate training facilities of a standard befitting a Premier League club."
