Implementation costs incurred by customers in CCAs are deferred if they would be capitalized by customers in software license arrangements under the existing internal-use software guidance.

We are currently evaluating the effect that this ASU will have on our consolidated financial statements. In August 2018, the FASB issued ASU No. 2018-13, Fair Value Measurement (Topic 820), which removes, modifies, and adds fair value disclosure requirements, including a new requirement to disclose the range and weighted average of significant observable inputs used to develop Level 3 fair value measurements. Certain disclosures are required to be adopted on a retrospective basis and others on a prospective basis. Although early adoption is permitted, we expect to adopt the new disclosure requirement for significant observable inputs for Level 3 fair value measurements when they become effective in January 1, 2020. This ASU is not expected to have a material effect on our consolidated financial statements.

Basis of Presentation

Principles of Consolidation

The unaudited condensed consolidated financial statements reflect our financial position, results of operations and cash flows, in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”). We have condensed or omitted certain information and footnote disclosures normally included in financial statements presented in accordance with U.S. GAAP. In our opinion, the accompanying unaudited condensed consolidated financial statements reflect all adjustments, including normal recurring items, considered necessary for a fair presentation of the interim periods. All significant intercompany transactions and balances within the financial statements have been eliminated.

These financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto for the year ended December 31, 2017 included in our Annual Report on Form 10-K, filed with the Securities and Exchange Commission (“SEC”) on March 1, 2018.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates. Interim results are not necessarily indicative of full year performance.

Reclassifications

Certain line items on the condensed consolidated statements of comprehensive income for the three and nine months ended September 30, 2017 and condensed consolidated statements of cash flows for the nine months ended September 30, 2017 have been reclassified to conform to the current period presentation.
