China Shanshui Cement Group has declared a full-year net loss of $988m for 2015 following a troubled year for the company that included the replacement of its entire board in December. The losses stem in part from a $360m write-down of goodwill assets due to ?forecasted less satisfactory results of operations of group companies in the foreseeable future and over-payment in the acquisitions of certain cement plants in the past,?Dow Jones reports.
