MILAN, Feb 12 (Reuters) - Italian insurer UnipolSai said on Friday group net profit in 2015 fell 5.8 percent to 738 million euros ($834 million) burdened by an 84 million euro charge regarding deferred taxes.

The combined ratio, a measure of profitability, stood at 93.9 percent, it said.
The insurer said it planned to pay a dividend on the year of 0.15 euros per share.
