DERIVATIVES AND HEDGE ACCOUNTING ACTIVITIES

DERIVATIVESAND HEDGE ACCOUNTING ACTIVITIES

Questar Gas uses derivative instruments to manage exposure to supply and price risk. As discussed in Note 2, changes in the fair value of derivatives are deferred as regulatory assets or regulatory liabilities until the related transactions impact earnings. See Note 5 for further information about fair value measurements and associated valuation methods for derivatives.

Derivative assets and liabilities are presented gross on Questar Gas' Balance Sheets. Questar Gas' derivative contracts include over-the-counter transactions, which are bilateral contracts that are transacted directly with a counterparty. At December 31, 2016, substantially all of Questar Gas' derivative assets and liabilities were not subject to a master netting or similar arrangement.

The following table presents the volume of Questar Gas' derivative activity at December 31, 2016. These volumes are based on open derivative positions and represent the combined absolute value of their long and short positions, except in the case of offsetting transactions, for which they represent the absolute value of the net volume of their long and short positions.
