The 2016 foreign deferred benefit includes the tax effect of a $341 million impairment associated with the Canadian operations (see Note 16 – Fair Value Measurements, Guarantees, and Concentration of Credit Risk). The 2015 state deferred benefit includes $7 million related to the impact of a Texas franchise tax rate decrease. The 2015 foreign deferred provision includes $8 million related to the impact of an Alberta provincial tax rate increase.
Income (loss) before income taxes includes $4 million and $387 million of foreign loss in 2017 and 2016, respectively, and $1 million of foreign income in 2015.
Deferred income tax liabilities, primarily attributable to the taxable temporary differences from property, plant, and equipment, were $16 million and $20 million in 2017 and 2016, respectively.
Cash payments for income taxes (net of refunds) were $12 million and $3 million in 2017 and 2016, respectively. Cash refunds for income taxes (net of payments) were $4 million in 2015.
As of December 31, 2017, we have no unrecognized tax benefits.
Tax years after 2013 are subject to examination by the Texas Comptroller. Generally, tax returns for our previously owned Canadian entities are open to audit for tax years after 2012. Tax years 2013 and 2014 are currently under examination. Williams has indemnified us for any adjustments to foreign tax returns filed prior to Pre-Merger WPZ’s acquisition of certain Canadian operations from Williams in 2014. We have indemnified the purchaser for any adjustments to foreign tax returns for periods prior to the sale of our Canadian operations in September 2016 (see Note 2 – Acquisitions and Divestitures).
