According to a recent filing submitted by Century Aluminum Company to the U.S. Securities and Exchange Commission, the company's gross profit margin for certain reporting periods was affected to some extent due to changes in accounting policies.

According to the disclosed information, this accounting adjustment has resulted in a decrease in gross profit margin, with the decline controlled within 10%. This financial data adjustment reflects the company’s compliance with updated accounting standards. Although it has some impact on short-term profit presentation, it does not alter the core business condition of the enterprise. When evaluating the company’s financial performance, investors should comprehensively consider the context of accounting policy changes.
