Crocs’ annual financial statements filed with the U.S. Securities and Exchange Commission include an unqualified audit opinion from its accountants that raises doubt about the company’s ability to continue as a going concern. The company, which reported a loss of $185.1 million in 2008, had $51.6 million in cash as of Dec. 31, with $22.4 million in borrowings under its revolving credit facility, which matures on April 2. Crocs has been working on extending the credit facility, and has also been in discussions with financial institutions to obtain an asset-backed lending arrangement. The 2008 report also notes a drop in revenue and one-time restructuring charges. While it made cost-cutting moves last year, it is considering further restructuring to offset potential continued sales declines.
