 Background:

 Revenue of Epistar Group was NTD 6.65 billion in the first quarter of 2015,

 an increase of 6.5% from NTD 6.24 billion for the first quarter of 2014 and

 an increase of 16.3% from NTD 5.72 billion for the fourth quarter of 2014.

 Gross margin for the Group was 11.8% for the first quarter of 2015, an

 decrease of 3.4% from 15.2% for the first quarter of 2014 and the fourth

 quarter of 2014. Even if gross margin rate for the first quarter of 2015

 is less than for the fourth quarter of 2014, the  revenue showed an

 increasing trend. The operating profit was 0.02 billion for the first

 quarter of 2015.

 Due to the subsequently measurement of convertible corporate bonds made

 in accordance with IFRS in the first quarter of 2015, the gains of

 NTD 0.67 billion was reported in the first quarter of 2015. As a result,

 a net income of NTD 0.71 billion was recognized for the first quarter

 of 2015. Conversion options, call options and put options embedded in

 convertible corporate bonds were stated at fair value at the balance

 sheet date. The gains were primarily due to lower liquidity risk and

 company stock price down compare to the end of first quarter.

 The valuation gains didn’t result in any cash inflow.

 If the above impact was excluded, the Group’s net income before tax

 for the first quarter of 2015 would be NTD 0.24 billion.
