The sales-to-production ratio remained unsatisfactory, and unit fixed costs for products were high. 2. Goodwill formed from enterprise mergers under not under common control was assessed and impairment of goodwill was accrued based on professional appraisal institutions’ evaluation. 3. The company focused on advancing construction of two major carbon fiber projects in Guangdong and Gansu, investing a large amount of capital, personnel, and management resources, resulting in high expenses. 4. Amortization of interest on proceeds from convertible bonds increased financial expenses.
