(CNN) -- Manchester United's financial state was thrown into stark relief on Thursday after the English club's American owners revealed a record loss of $137 million despite making an unprecedented operating profit of $160 million. The disparity of figures is largely caused by interest payments of $67 million and a one-off cost of $107 million relating to the Premier League outfit's bond scheme, launched in January to help restructure the debts accrued by the Glazer family in purchasing the 18-time English champions in 2005. The club produced a record turnover of $455 million for the year ended June 2010, more than double that of local rivals Manchester City, but suffered a big swing from last year's profit of $77 million -- which was largely due to the world-record $130 million sale of Cristiano Ronaldo to Real Madrid.Man Utd's owners make record loss of $137 million despite operating profit of $160 millionGlazer family's debts incurred in buying English club in 2005 largely to blameThe 18-time English champions' turnover for year ended June 2010 was $455 millionUnited's wage bill is only 46 percent of turnover, the lowest ratio in Premier League
