Imperial Sugar Co. announced Thursday it has not filed its annual report for the year ended Sept. 30, partly because the company has not received audited financial statements from Louisiana Sugar Refining LLC, owner of the new Gramercy sugar mill.

Louisiana Sugar Refining, a three-way investment involving Cargill, Imperial and Sugar Growers and Refiners, took over the operations of the existing Imperial facility at Gramercy and built a new refinery that began producing sugar earlier this year.

Imperial also said it will take more time to complete its financial statement and for an audit of those statements. The company has asked the U.S. Securities and Exchange Commission for additional time and expects to file the annual report by Dec. 29.
