Accounting Changes and Error Corrections [Abstract]
Accounting Standards	Effective January 1, 2017, the company adopted new guidance issued by the Financial Accounting Standards Board (“FASB”) which simplifies how an entity is required to test goodwill for impairment by eliminating Step 2 from the goodwill impairment test. Step 2 measures a goodwill impairment loss by comparing the implied fair value of a reporting unit’s goodwill with the carrying amount of that goodwill. Under the amended guidance, an entity will perform its annual or interim goodwill impairment test by comparing the fair value of a reporting unit with its carrying amount. An impairment charge will be recognized for the amount by which the carrying amount exceeds the reporting unit’s fair value. Adoption of this new guidance had no impact on the company’s consolidated results of operations and financial position. Effective January 1, 2017, the company adopted new guidance issued by the FASB which allows the recognition of deferred income taxes for an intra-entity asset transfer, other than inventory, when the transfer occurs. Historically, recognition of the income tax consequence was not recognized until the asset was sold to an outside party. The new guidance has been applied on a modified retrospective basis through a cumulative-effect adjustment directly to accumulated deficit. At January 1, 2017, the adjustment to accumulated deficit was an increase of $4.4 million. Effective January 1, 2017, the company adopted new guidance which clarifies the treatment of several cash flow categories. In addition, the guidance also clarifies that when cash receipts and cash payments have aspects of more than one class of cash flows and cannot be separated, classification will depend on the predominant source or use. The company previously reported premium payments on and proceeds from the settlement of corporate-owned life insurance policies as cash flows from operating activities in the company’s consolidated statement of cash flows. Under the new guidance, these amounts were reclassified to investing activities. The new guidance has been applied on a retrospective basis whereby prior-period financial statements have been adjusted to reflect the application of the new guidance, as required by the FASB. For the six months ended June 30, 2016, $0.8 million was reclassified from “(increase) decrease in other assets” in operating activities to “other” in investing activities in the company’s consolidated statements of cash flows. Effective January 1, 2017, the company adopted new guidance that changes certain aspects of accounting for share-based payments to employees. The new guidance requires all income tax effects of awards to be recognized in the income statement when the awards vest or are settled. It also allows an employer to repurchase more of an employee’s shares than it can today for tax withholding purposes without triggering liability accounting and to make a policy election to account for forfeitures as they occur. Additionally, the standard requires all tax-related cash flows resulting from share-based payments to be reported as operating activities on the consolidated statement of cash flows, and any cash payments made to taxing authorities on an employee’s behalf as financing activities, which the company previously reported as operating activities. The new guidance has been applied on a retrospective basis whereby prior-period financial statements have been adjusted to reflect the application of the new guidance, as required by the FASB. For the six months ended June 30, 2016, $0.4 million was reclassified from “decrease in accounts payable and other accrued liabilities” in operating activities to “other” in financing activities in the company’s consolidated statements of cash flows. Effective January 1, 2017, the company adopted new guidance issued by the FASB which requires companies to include amounts generally described as restricted cash or restricted cash equivalents with cash and cash equivalents when reconciling the beginning-of-period and end-of-period total amounts shown on the statement of cash flows. The new guidance has been applied on retrospective basis whereby prior-period financial statements have been adjusted to reflect the application of the new guidance, as required by the FASB. For the six months ended June 30, 2016, the reclassification in the consolidated statements of cash flows resulted in a $3.1 million reduction to “(increase) decrease in other assets” in operating activities, a $1.3 million increase in “other” in investing activities, a $0.4 million increase in “effect of exchange rate changes on cash, cash equivalents and restricted cash,” a $31.6 million increase in “cash, cash equivalents and restricted cash, beginning of period” and a $30.2 million increase in “cash, cash equivalents and restricted cash, end of period.” In March 2017, the FASB issued new guidance on the presentation of net periodic benefit cost in the income statement. The new guidance requires employers to present the service cost component of net periodic benefit cost in the same income statement line item(s) as other employee compensation costs arising from services rendered during the period. Only the service cost component will be eligible for capitalization in assets. The other components of net periodic benefit cost will be presented separately from the line items that include service cost and outside the subtotal of operating income. This update is effective for annual periods beginning after December 15, 2017, which for the company is January 1, 2018. Adoption of this new guidance will result in the reclassification of net periodic benefit cost, other than service costs ($42.6 million for the six months ended June 30, 2017), from operating income to non-operating income. There will be no overall impact on the company’s consolidated financial position. In June 2016, the FASB issued new guidance that introduces a new model for recognizing credit losses on financial instruments based on an estimate of current expected losses. This includes trade and other receivables, loans and other financial instruments. This update is effective for annual periods beginning after December 15, 2019, with earlier adoption permitted. The company is currently assessing when it will choose to adopt, and is currently evaluating the impact of the adoption on its consolidated financial statements. In February 2016, the FASB issued a new lease accounting standard entitled “Leases.” The new standard is intended to improve financial reporting about leasing transactions. The new rule will require organizations that lease assets, referred to as lessees, to recognize on the balance sheet the assets and liabilities for the rights and obligations created by those leases. The standard requires disclosures to help investors and other financial statement users better understand the amount, timing and uncertainty of cash flows arising from leases. The standard is effective for annual reporting periods beginning after December 15, 2018, which for the company is January 1, 2019. Earlier adoption is permitted. The company is currently assessing when it will choose to adopt, and is currently evaluating the impact of the adoption on its consolidated results of operations and financial position. In 2014, the FASB issued a new revenue recognition standard entitled “Revenue from Contracts with Customers.” The objective of the standard is to establish the principles that an entity shall apply to report useful information to users of financial statements about the nature, amount, timing and uncertainty of revenue and cash flows from a contract with a customer. The standard, and its various amendments, is effective for annual reporting periods beginning after December 15, 2017, which for the company is January 1, 2018. The standard allows for either “full retrospective” adoption, meaning the standard is applied to all periods presented, or “modified retrospective” adoption, meaning the standard is applied only to the most current period presented in the financial statements. Generally the new standard would require the company to recognize revenue for certain transactions, including extended payment term software licenses and short-term software licenses, sooner than the current rules would allow. The company will adopt the standard on January 1, 2018 using the modified retrospective method. The company is currently monitoring the impact the adoption of this new standard will have on its consolidated results of operations and financial position and currently does not believe there will be a material impact upon adoption or on a go-forward basis. However, the final impact cannot be determined until the end of 2017 and it will be impacted by transactions entered into during 2017.
