"The export duty is calculated using the following formula: at a price of $333.3 and more per 1,000 thousand cubic meters of gas, the price drop will amount to $100, while at a price lower than $333.3 the price drop will amount to 30% of such prices," the explanatory note for the decree says.

It is also noted that the signed decree will extend the preferential treatment of the supplies of natural gas from the Russian Federation to Ukraine from April 1 to June 30, 2015.
