South Africa's Anglo American Platinum Ltd (Amplats) reported an 86 percent drop in full-year profit on Monday, hit by write-downs and restructuring costs amid plunging commodity prices.

Amplats said diluted headline earnings per share, the main gauge of profit that strips off certain one-off items, totalled 41 cents in the year to the end of December compared with 300 cents a year earlier.
