The significant transactions were as follows:-

1. Share of profits in associate entities and joint ventures

Share of profits in associate entities and joint ventures for the year 2017 was Baht 3,577.16 million, increasing by Baht 669.96 million or 23.0 percent from Baht 2,907.20 million in the year 2016. The main reasons were as follows:-

(1) The profit of Hongsa Power Company Limited ("HPC"), a joint venture, in a portion of 40 percent increased in the amount of Baht 821.62 million; as well as, the profit of Phu Fai Mining Company Limited, a joint venture for coal mining and trading to HPC, in a portion of 37.5 percent increased in the amount of Baht 47.60 million, as Hongsa Power Plants generated electricity more than the previous year. In addition, Hongsa Power Plants have commenced commercial operation for 3 units on September 2, 2015, November 2, 2015, and March 2, 2016, respectively.

(2) The profit of Navanakorn Electricity Generating Company Limited, a joint venture, in a portion of 40 percent, increased in the amount of Baht 103.26 million as the power plant has commenced commercial operation on June 3, 2016.

(3) The loss of Xe-Pian Xe-Namnoy Power Company Limited, an under construction joint venture, in a portion of 25 percent, was Baht 152.75 million in the year 2017 due to the loss on exchange rate in the amount of Baht 136.75 million. In the year 2016, the figures showed the profit in the amount of Baht 60.16 million due to the gain on exchange rate in the amount of Baht 75.51 million.

(4) The profit of Ratchaburi Power Company Limited, a joint venture, in a portion of 25 percent, decreased in the amount of Baht 126.49 million. The main reason was the decrease in revenue from finance lease contracts in the amount of Baht 99.84 million. Additionally, the power plant generated electricity less than the previous year.

2. Revenue from Sales and Rendering of Services (excluding fuel costs)

Revenue from sale and rendering of services for the year 2017 was Baht 6,656.26 million

The main reason was the increase in revenue from sale of Ratchaburi Electricity Generating Company Limited, a subsidiary, in the amount of Baht 556.72 million due to the increase in Base Availability Credit in 2017 compared to that of 2016, as specified in the Power Purchase Agreement. Meanwhile, revenue from operation and maintenance services of RATCH-Lao Services Company Limited, a subsidiary, decreased by Baht 188.38 million as it has transferred its rights of such service agreement to Nam Ngum 2 Power Company Limited in April 2016, in exchange for the Baht 134.71 million remedy.

3. Cost of sale and rendering of services (excluding fuel costs)

Cost of sale and rendering of services for the year 2017 was Baht 5,503.11 million
