Recently Issued Accounting Standards	Recently Issued Accounting Standards There have been no developments to recently issued accounting standards, including the expected dates of adoption and estimated effects on the Company's consolidated financial statements and note disclosures, from those disclosed in the Company's 2016 Annual Report on Form 10-K, that would be expected to impact the Company except for the following: In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, “Revenue from Contracts with Customers”, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers. The ASU will replace most existing revenue recognition guidance in U.S. GAAP when it becomes effective. In August 2015, the FASB issued ASU No. 2015-14, delaying the effective date of ASU 2014-09. Three other amendments have been issued during 2016 modifying the original ASU. As amended, the new standard is effective for the Company on January 1, 2018, using either a retrospective basis or a modified retrospective basis with early adoption permitted. The Company plans to adopt the standard effective January 1, 2018 using the modified retrospective transition approach; under this approach prior periods will not be retrospectively adjusted. The Company is continuing to assess all potential impacts of the standard, including the impact to the pattern with which revenue and direct and contract fulfillment costs are recognized, the impact of the standard on current accounting policies, practices and system of internal controls, in order to identify material differences, if any that would result from applying the new requirements. The Company is in the process of establishing new policies and processes, and is implementing necessary changes to data and procedures necessary to comply with the new requirements. While continuing to assess all potential impacts of the standard, the Company believes the adoption will not have a significant effect on earnings however, the presentation of certain costs may change and disclosures will be impacted. The Company is still in the process of evaluating the impacts and the initial assessment may change. In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities”. In addition to the presentation and disclosure requirements for financial instruments, ASU 2016-01 requires entities to measure equity investments, other than those accounted for under the equity method, at fair value and recognize changes in fair value in net income. Entities will no longer be able to use the cost method of accounting for equity securities. However, for equity investments without readily determinable fair values that do not qualify for the practical expedient to estimate fair value using net asset value per share, entities may elect a measurement alternative that will allow those investments to be recorded at cost, less impairment, and adjusted for subsequent observable price changes. Entities must record a cumulative-effect adjustment to the balance sheet as of the beginning of the first reporting period in which the standard is adopted, except for equity investments without readily determinable fair values, for which the guidance will be applied prospectively. The guidance under ASU 2016-01 is effective for annual and interim periods beginning after December 15, 2017. The Company has not yet completed its assessment of the impact of the new standard on the Company’s consolidated financial statements. In February 2016, the FASB issued ASU No. 2016-02, “Leases”, which requires the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous generally accepted accounting principles. The ASU is effective for us on January 1, 2019, and early application is permitted. Modified retrospective application is required. The Company plans to adopt this standard when it becomes effective for the Company beginning January 1, 2019, and expects the adoption of this standard will result in the recognition of right of use assets and lease liabilities that have not previously been recorded, which will have a material impact on the Company’s consolidated financial statements. In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 is intended to reduce diversity in practice in how certain cash receipts and cash payments are presented and classified in the Consolidated Statement of Cash Flows by providing guidance on eight specific cash flow issues. The Company intends to adopt the standard retrospectively on the effective date of January 1, 2018 and does not expect the adoption of the ASU to have a material effect on cash flows. In March 2017, the FASB issued ASU No. 2017-07, "Improving the Presentation of Net Periodic Pension Cost and Net Periodic Postretirement Benefit Cost". The update requires employers to present the service cost component of the net periodic benefit cost in the same income statement line item as other employee compensation costs arising from services rendered during the period. The other components of net benefit cost, including interest cost, expected return on plan assets, amortization of prior service cost/credit and actuarial gain/loss, and settlement and curtailment effects, are to be presented outside of any subtotal of operating income. Employers will have to disclose the line(s) used to present the other components of net periodic benefit cost, if the components are not presented separately in the income statement. ASU 2017-07 is effective for fiscal years and interim periods beginning after December 15, 2017, and early adoption is permitted. The Company is currently assessing the impact that adopting this new accounting standard will have on its consolidated financial statements. The Company does not expect the adoption of ASU 2017-07 to have a material impact on its consolidated financial statements, nor does the Company expect to early adopt ASU 2017-07. In August 2017, the FASB issued ASU 2017-12, "Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities". This update is intended to simplify hedge accounting by better aligning an entity’s financial reporting for hedging relationships with its risk management activities. The ASU also simplifies the application of the hedge accounting guidance. ASU 2017-12 is effective on January 1, 2019, with early adoption permitted. For cash flow hedges existing at the adoption date, the standard requires adoption on a modified retrospective basis with a cumulative-effect adjustment to the Consolidated Balance Sheet as of the beginning of the year of adoption, to the extent any ineffectiveness was previously recognized. The amendments to presentation guidance and disclosure requirements under this update are required to be adopted prospectively. The Company has not yet determined the effect of the ASU on our results of operations, financial condition or cash flows, nor has transition date been determined. In September 2017, the FASB issued ASU No. 2017-13, "Revenue Recognition (Topic 605), Revenue from Contracts with Customers (Topic 606), Leases (Topic 840), and Leases (Topic 842)", which provided additional implementation guidance on the previously issued topics. The Company has not yet completed its assessment of the impact of the new standard on the Company’s consolidated financial statements.

Recently Issued Accounting Standards

There have been no developments to recently issued accounting standards, including the expected dates of adoption and estimated effects on the Company's consolidated financial statements and note disclosures, from those disclosed in the Company's 2016 Annual Report on Form 10-K, that would be expected to impact the Company except for the following:

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") No. 2014-09, “Revenue from Contracts with Customers”, which requires an entity to recognize the amount of revenue to which it expects to be entitled for the transfer of promised goods or services to customers.

The Company plans to adopt the standard effective January 1, 2018 using the modified retrospective transition approach; under this approach prior periods will not be retrospectively adjusted.

The Company is continuing to assess all potential impacts of the standard, including the impact to the pattern with which revenue and direct and contract fulfillment costs are recognized, the impact of the standard on current accounting policies, practices and system of internal controls, in order to identify material differences, if any that would result from applying the new requirements.

The Company is in the process of establishing new policies and processes, and is implementing necessary changes to data and procedures necessary to comply with the new requirements.
