In 2Q17 the Company recorded a net income of R$ 331.8 million, in comparison to a net income of R$ 797.5 million in 2Q16.

2. Gross operating revenue

The main factors that led to this variation were:

· Tariff increase of 8.4% since May 2016;

· Increase of 2.7% in the Company’s total billed volume (2.9% in water and 2.4% in sewage);

· Bonus granted in 2Q16 amounting to R$ 33.6 million, within the Water Consumption Reduction Incentive Program ended in April 2016; and

· Lower provisioning for loss of wholesale revenue in 2Q17, in the amount of R$ 21.0 million, due to the payment received in the period.

Page 2 of 11

The increase resulting from the above mentioned factors was partially offset by the suspension of the Contingency Tariff in April 2016, in the amount of R$ 64.2 million in 2Q16.

3. Construction revenue

Construction revenue decreased R$ 117.8 million or 13.1%, when compared to 2Q16. The variation was mainly due to lower investments in the municipalities served by the Company.

6.1.1. Financial expenses

Decrease of R$ 7. 9 million, mainly due to the following events:

· Interest and charges on international loans and financing: increase of R$ 5.1 million, mainly due to the appreciation of the dollar and the yen against the real at the end of 2Q17 (4.4% and 3.5%, respectively), versus a depreciation in 2Q16 (-9.8% and -1.4%, respectively);

· Interest and charges on domestic loans and financing: reduction of R$ 7.1 million, mainly due to a decline in the debt balance following the partial amortizations of the 10th and 15th debenture issues in January and February 2017, respectively, and the full amortization of the 19th issue in June 2017; and

· Other financial expenses: reduction of R$ 5.9 million, mostly due to lower provisioning for interest on court proceedings in 2Q17.

6.2.1 Monetary and exchange rate variation on liabilities

The effect of monetary and currency variations in 2Q17 was R$ 655.3 million higher than in 2Q16, mainly due to:

· Reduction of R$ 13.7 million in expenses with monetary variation on loans and financing, due to the lower variation in the IPCA in 2Q17 compared with 2Q16 (0.2% and 1.8%, respectively); and

· Increase of R$ 672.9 million in exchange variation on loans and financing, as a result of the appreciation of dollar and yen against the real in 2Q17 (4.4% and 3.5%, respectively), versus a devaluation of 9.8% and 1.4%, respectively, in 2Q16.

6.2.2 Monetary and exchange rate variation on assets

Decrease of R$ 8.4 million, mainly due to the lower monetary restatement of judicial deposits in 2Q17.

7. Income tax and social contribution

Decrease of R$ 2 67.4 million, mainly due to the lower taxable result reported in the period, which was mainly impacted by the appreciation of dollar and yen against the real in 2Q17, versus a devaluation in 2Q16.
