New Accounting Pronouncements and Changes in Accounting Principles [Abstract]
Recent Accounting Pronouncements	RECENT ACCOUNTING PRONOUNCEMENTS The Company implemented the following accounting standards during the six months ended June 30, 2017: In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2016-09, "Compensation - Stock Compensation (Topic 718)," as a part of its simplification initiative. The Company adopted this ASU during the six months ended June 30, 2017. Key areas of the amendments in this standard are (i) all excess tax benefits (deficiencies) from stock plan transactions should be recognized in the income statement as opposed to being recognized in additional paid-in capital; (ii) the tax withholding threshold for triggering liability accounting on a net settlement transaction has been increased from the minimum statutory rate to the maximum statutory rate; and (iii) an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur. The guidance also provides clarification of the presentation of certain components of share-based awards in the statement of cash flows. The Company has elected to continue estimating forfeitures expected to occur in order to determine the amount of compensation cost to be recognized each period and to apply the cash flow classification guidance prospectively. As a result, excess tax benefits are now classified as an operating activity rather than a financing activity and the Company has recorded $1.4 million of excess tax benefits from stock plan transactions as a component of income tax expense in the consolidated statement of operations for the six months ended June 30, 2017. The Company has excluded the excess tax benefits from the assumed proceeds available to repurchase shares in the computation of its diluted earnings per share for the six months ended June 30, 2017. In March 2016, the FASB issued ASU 2016-05, "Derivatives and Hedging," which clarifies that a change in the counter party to a derivative instrument that has been designated as a hedging instrument does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The Company adopted this ASU during the six months ended June 30, 2017 and elected to to apply the amendments in this standard on a prospective basis. The implementation of this standard did not have a material impact on the Company's financial position, results of operations or cash flows. In March 2016, the FASB issued ASU 2016-07, "Investments - Equity Method and Joint Ventures," as a part of its simplification initiative. The amendments in this standard eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in ASU 2016-07 also require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The Company adopted this ASU during the six months ended June 30, 2017 and elected to to apply the amendments in this standard on a prospective basis. The implementation of this standard did not have a material impact on the Company's financial position, results of operations or cash flows. In October 2016, the FASB issued ASU No. 2016-17, "Consolidation - Interest Held through Related Parties that are Under Common Control," which amends the current consolidation guidance on how a reporting entity that is the single decision maker of a variable interest entity ("VIE") should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The primary beneficiary of a VIE is the reporting entity that has a controlling financial interest in a VIE, and therefore consolidates the VIE. A reporting entity has an indirect interest in a VIE if it has a direct interest in a related party that, in turn, has a direct interest in the VIE. The Company adopted this ASU during the six months ended June 30, 2017. The implementation of this standard did not have a material impact on the Company's financial position, results of operations or cash flows. The following accounting standards will be adopted in future periods: In May 2017, the FASB issued ASU No. 2017-10 "Service Concession Arrangements - Determining the Customer of the Operation Services". The objective of this guidance is to reduce diversity in practice and provide clarification on how an operating entity determines the customer of the operation services for transactions within the scope of Topic 853, Service Concessions Arrangements. The amendments in this update clarify that the grantor is the customer of the operation services in all cases for such arrangements. The new standard is effective for the Company beginning on January 1, 2018. The adoption of this standard is not expected to have a material impact on the Company's financial position, results of operations or cash flows. In May 2017, the FASB issued ASU No. 2017-09 "Compensation - Stock Compensation". The objective of this guidance is to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying modification accounting for changes in the terms or conditions of share-based payment awards. An entity should account for the effects of a modification unless all of the following factors are met: (i) the fair value of the modified award is the same as the fair value of the original award immediately before the award is modified; (ii) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and (iii) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The new standard will be effective for all entities for fiscal years beginning after December 15, 2017 with early adoption permitted for public companies for reporting periods for which financial statements have not yet been issued. The amendments in this update should be applied prospectively to an award modified on or after the adoption date. The adoption of this standard is not expected to have a material impact on the Company's financial position, results of operations or cash flows. In March 2017, the FASB issued ASU No. 2017-07 "Compensation - Retirement Benefits (Topic 715)-Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost". This guidance revises how employers that sponsor defined benefit pension and other postretirement plans present the net periodic benefit cost in their income statement and requires that the service cost component of net periodic benefit cost be presented in the same income statement line items as other employee compensation costs from services rendered during the period. Of the components of net periodic benefit cost, only the service cost component will be eligible for asset capitalization. The other components of the net periodic benefit cost must be presented separately from the line items that include the service cost and outside of any subtotal of operating income on the income statement. The new standard will be effective for public companies for fiscal years beginning after December 15, 2017 on a retroactive basis. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company's financial position, results of operations or cash flows. In February 2016, FASB issued ASU 2016-02, "Leases," which requires entities to recognize lease assets and lease liabilities on the balance sheet and to disclose key information about leasing arrangements. For finance leases and operating leases, a lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term with each initially measured at the present value of the lease payments. The amendments in ASU 2016-02 are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company has implemented a lease management software application tool and is currently assessing the impact that the adoption of ASU 2016-02 will have on its consolidated financial position or results of operations, but expects that it will result in a significant increase in its long-term assets and liabilities given the significant number of leases the Company is a party to. In May 2014, the FASB issued a new standard related to revenue recognition (ASU 2014-09, "Revenue from Contracts with Customers".) Under the new standard, revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. In addition, the standard requires disclosure of the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. The FASB has recently issued several amendments to the standard, including clarification on accounting for licenses of intellectual property and identifying performance obligations. The guidance permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective transition method). The new standard is effective for the Company beginning on January 1, 2018. The Company is currently in the process of evaluating whether these standards would have a material impact on the Company's financial position, results of operation or cash flows. However, upon its initial assessment, the Company believes that the timing of revenue recognition could potentially be affected as it relates to certain variable consideration arrangements with certain of its customers. However, at this time, the Company does not believe this would result in a material impact on the Company's financial position, results of operations or cash flows. The Company has also initially determined that it will likely use the modified retrospective transition method to implement this standard, however, that election, as well as its analysis of any impacts related to variable consideration arrangements, may change once the Company's final assessment is completed.

RECENT ACCOUNTING PRONOUNCEMENTS

The Company implemented the following accounting standards during the six months ended June 30, 2017:

In March 2016, the Financial Accounting Standards Board ("FASB") issued Accounting Standard Update ("ASU") No. 2016-09, "Compensation - Stock Compensation (Topic 718)," as a part of its simplification initiative. The Company adopted this ASU during the six months ended June 30, 2017. Key areas of the amendments in this standard are (i) all excess tax benefits (deficiencies) from stock plan transactions should be recognized in the income statement as opposed to being recognized in additional paid-in capital; (ii) the tax withholding threshold for triggering liability accounting on a net settlement transaction has been increased from the minimum statutory rate to the maximum statutory rate; and (iii) an entity can make an entity-wide accounting policy election to either estimate the number of awards that are expected to vest or account for forfeitures as they occur. The guidance also provides clarification of the presentation of certain components of share-based awards in the statement of cash flows. The Company has elected to continue estimating forfeitures expected to occur in order to determine the amount of compensation cost to be recognized each period and to apply the cash flow classification guidance prospectively. As a result, excess tax benefits are now classified as an operating activity rather than a financing activity and the Company has recorded $1.4 million of excess tax benefits from stock plan transactions as a component of income tax expense in the consolidated statement of operations for the six months ended June 30, 2017. The Company has excluded the excess tax benefits from the assumed proceeds available to repurchase shares in the computation of its diluted earnings per share for the six months ended June 30, 2017.

In March 2016, the FASB issued ASU 2016-05, "Derivatives and Hedging," which clarifies that a change in the counter party to a derivative instrument that has been designated as a hedging instrument does not, in and of itself, require dedesignation of that hedging relationship provided that all other hedge accounting criteria continue to be met. The Company adopted this ASU during the six months ended June 30, 2017 and elected to to apply the amendments in this standard on a prospective basis. The implementation of this standard did not have a material impact on the Company's financial position, results of operations or cash flows.

In March 2016, the FASB issued ASU 2016-07, "Investments - Equity Method and Joint Ventures," as a part of its simplification initiative. The amendments in this standard eliminate the requirement that when an investment qualifies for use of the equity method as a result of an increase in the level of ownership interest or degree of influence, an investor must adjust the investment, results of operations, and retained earnings retroactively on a step-by step basis as if the equity method had been in effect during all previous periods that the investment had been held. The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor's previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. Therefore, upon qualifying for the equity method of accounting, no retroactive adjustment of the investment is required. The amendments in ASU 2016-07 also require that an entity that has an available-for-sale equity security that becomes qualified for the equity method of accounting recognize through earnings the unrealized holding gain or loss in accumulated other comprehensive income at the date the investment becomes qualified for use of the equity method. The Company adopted this ASU during the six months ended June 30, 2017 and elected to to apply the amendments in this standard on a prospective basis. The implementation of this standard did not have a material impact on the Company's financial position, results of operations or cash flows.

In October 2016, the FASB issued ASU No. 2016-17, "Consolidation - Interest Held through Related Parties that are Under Common Control," which amends the current consolidation guidance on how a reporting entity that is the single decision maker of a variable interest entity ("VIE") should treat indirect interests in the entity held through related parties that are under common control with the reporting entity when determining whether it is the primary beneficiary of that VIE. The primary beneficiary of a VIE is the reporting entity that has a controlling financial interest in a VIE, and therefore consolidates the VIE. A reporting entity has an indirect interest in a VIE if it has a direct interest in a related party that, in turn, has a direct interest in the VIE. The Company adopted this ASU during the six months ended June 30, 2017. The implementation of this standard did not have a material impact on the Company's financial position, results of operations or cash flows.

The following accounting standards will be adopted in future periods:

In May 2017, the FASB issued ASU No. 2017-10 "Service Concession Arrangements - Determining the Customer of the Operation Services". The objective of this guidance is to reduce diversity in practice and provide clarification on how an operating entity determines the customer of the operation services for transactions within the scope of Topic 853, Service Concessions Arrangements. The amendments in this update clarify that the grantor is the customer of the operation services in all cases for such arrangements. The new standard is effective for the Company beginning on January 1, 2018. The adoption of this standard is not expected to have a material impact on the Company's financial position, results of operations or cash flows.

In May 2017, the FASB issued ASU No. 2017-09 "Compensation - Stock Compensation". The objective of this guidance is to provide clarity and reduce both (1) diversity in practice and (2) cost and complexity when applying modification accounting for changes in the terms or conditions of share-based payment awards. An entity should account for the effects of a modification unless all of the following factors are met: (i) the fair value of the modified award is the same as the fair value of the original award immediately before the award is modified; (ii) the vesting conditions of the modified award are the same as the vesting conditions of the original award immediately before the original award is modified; and (iii) the classification of the modified award as an equity instrument or a liability instrument is the same as the classification of the original award immediately before the original award is modified. The new standard will be effective for all entities for fiscal years beginning after December 15, 2017 with early adoption permitted for public companies for reporting periods for which financial statements have not yet been issued. The amendments in this update should be applied prospectively to an award modified on or after the adoption date. The adoption of this standard is not expected to have a material impact on the Company's financial position, results of operations or cash flows.

In March 2017, the FASB issued ASU No. 2017-07 "Compensation - Retirement Benefits (Topic 715)-Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost". This guidance revises how employers that sponsor defined benefit pension and other postretirement plans present the net periodic benefit cost in their income statement and requires that the service cost component of net periodic benefit cost be presented in the same income statement line items as other employee compensation costs from services rendered during the period. Of the components of net periodic benefit cost, only the service cost component will be eligible for asset capitalization. The other components of the net periodic benefit cost must be presented separately from the line items that include the service cost and outside of any subtotal of operating income on the income statement. The new standard will be effective for public companies for fiscal years beginning after December 15, 2017 on a retroactive basis. Early adoption is permitted. The adoption of this standard is not expected to have a material impact on the Company's financial position, results of operations or cash flows.

In February 2016, FASB issued ASU 2016-02, "Leases," which requires entities to recognize lease assets and lease liabilities on the balance sheet and to disclose key information about leasing arrangements. For finance leases and operating leases, a lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term with each initially measured at the present value of the lease payments. The amendments in ASU 2016-02 are effective for public companies for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. The Company has implemented a lease management software application tool and is currently assessing the impact that the adoption of ASU 2016-02 will have on its consolidated financial position or results of operations, but expects that it will result in a significant increase in its long-term assets and liabilities given the significant number of leases the Company is a party to.

In May 2014, the FASB issued a new standard related to revenue recognition (ASU 2014-09, "Revenue from Contracts with Customers".) Under the new standard, revenue is recognized when a customer obtains control of promised goods or services and is recognized in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services.

The new standard is effective for the Company beginning on January 1, 2018. The Company is currently in the process of evaluating whether these standards would have a material impact on the Company's financial position, results of operation or cash flows. However, upon its initial assessment, the Company believes that the timing of revenue recognition could potentially be affected as it relates to certain variable consideration arrangements with certain of its customers. However, at this time, the Company does not believe this would result in a material impact on the Company's financial position, results of operations or cash flows. The Company has also initially determined that it will likely use the modified retrospective transition method to implement this standard, however, that election, as well as its analysis of any impacts related to variable consideration arrangements, may change once the Company's final assessment is completed.
