New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
New Accounting Pronouncements and Changes in Accounting Principles	New Accounting Pronouncements Standards adopted in 2018 Revenue Recognition On January 1, 2018, we adopted the comprehensive new revenue recognition standard issued by the Financial Accounting Standards Board (FASB). The core principle of the new guidance is that a company should recognize revenue to depict the transfer of promised services or products to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those services or products. The standard creates a five step model that requires companies to exercise judgment when considering the terms of a contract and all relevant facts and circumstances. We adopted the new revenue recognition standard using a modified retrospective basis and applied the guidance to all contracts that were not completed as of January 1, 2018. This resulted in an immaterial cumulative-effect adjustment to retained earnings as of January 1, 2018. The comparative financial information has not been restated and continues to be reported under the revenue accounting standards in effect during those periods. The adoption of this standard did not have a material impact to our condensed consolidated financial position, reported revenue, results of operations or cash flows as of and for the three months ended March 31, 2018. See Note 3 for our expanded revenue disclosures required by the new standard. Standards not yet adopted Leases In February 2016, the FASB issued an accounting standards update related to accounting for leases, which requires the assets and liabilities that arise from leases to be recognized on the balance sheet. Currently only capital leases are recorded on the balance sheet. This update will require the lessee to recognize a lease liability equal to the present value of the lease payments and a right-of-use asset representing its right to use the underlying asset for the lease term for all leases longer than 12 months. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and liabilities and recognize the lease expense for such leases generally on a straight-line basis over the lease term. This update will be effective for fiscal periods beginning after December 15, 2018, including interim periods within that reporting period. Early adoption is permitted. We are currently evaluating the impact that this update will have on our condensed consolidated financial statements.

Revenue Recognition

On January 1, 2018, we adopted the comprehensive new revenue recognition standard issued by the Financial Accounting Standards Board (FASB).
