So, you think you can restructure your debt, Core Media?

Core Media Group, the owner of the production company for reality TV programs such as American Idol and So You Think You Can Dance, has reportedly filed for Chapter 11 bankruptcy protection. The New York-based company said in its bankruptcy filing that it carries $398 million in debt, with creditors that include American Idol creator Simon Fuller, according to The Hollywood Reporter.

Core Media is owned as a joint venture—formed in 2014—between 21st Century Fox (FOX) and private equity firm Apollo Global Management.

Fuller is owed nearly $3.4 million by the company, which said in its filing on Thursday that Fuller demanding payment was one factor that played into Core Media’s decision to file for bankruptcy, THR reports. Other creditors include former Core Media CEO Marc Graboff, now studio head at Discovery Communications, as well as a group of investment funds that issued Core Media two matured loans.

In a statement e-mailed to Fortune by a Core Media spokesperson, the company said that the Chapter 11 restructuring “will help best position the company for the future, allowing for more flexibility and a platform for growth.”

“Core Media Group remains firmly committed to our mission as a global content and management company producing award-winning programming,” the company said.

Core Media predecessor company CKX bought 19 Entertainment, the production company behind American Idol and So You Think You Can Dance, in 2005 from the British TV producer Fuller. Core Media also owns the production company Sharp Entertainment, which produces unscripted series such as Man v. Food and Call of the Wildman, as well as B-17 Entertainment. (Core Media said in a statement that Sharp and B-17 are not involved in the bankruptcy proceedings.)

The Chapter 11 move comes less than a month after American Idol aired its final episode following 15 seasons on the air. The Fox show was part of the early wave of reality television programs that helped spur the growth of that TV genre, with Idol’s viewership topping out at more than 37 million viewers (for its sixth season premiere, in 2007) before sagging ratings in recent seasons led to the show’s cancellation.

THR also reports that Core Media submitted a declaration in court along with the Chapter 11 filing, stating: “Despite its long-running success . . . [Core Media] has recently experienced deterioration in its financial performance, primarily attributable to the decline in ratings for American Idol and the corresponding decline in revenues from Idol-related broadcast fees, international tape sales for rebroadcasts, touring fees, sponsorships and Idol-related merchandise sales.”
