Recently Adopted & Not Yet Adopted Accounting Pronouncements	Recent Accounting Pronouncements Not Yet Adopted In February 2016, the Financial Accounting Standards Board ("FASB") issued an accounting standard update ASU 2016-02, "Leases," which requires that lease arrangements longer than 12 months result in an entity recognizing an asset and liability on its balance sheet. ASU 2016-02 is effective for interim and annual periods beginning after December 15, 2018, and early adoption is permitted. This accounting standard update will be effective for the Company on January 1, 2019. For operating leases with terms longer than 12 months, the Company will recognize a lease liability for the obligation to make lease payments and a right-of-use asset for the right to use the underlying asset for the lease term. The Company is currently in the process of evaluating the impact of the adoption on its financial position, results of operations and cash flows. In February 2018, the FASB issued Accounting Standards Update No. 2018-02, "Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income", which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from the Tax Cuts and Jobs Act, eliminating the stranded tax effects resulting from the Tax Cuts and Jobs Act. However, the new guidance only applies to the tax effects resulting from the Tax Cuts and Jobs Act and does not change the underlying guidance to recognize the effect of a change in tax laws or rates in income from continuing operations. The amendments are effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. The Company is currently in the process of evaluating the impact of the adoption on its financial position, results of operations and cash flows. (c) Recently Adopted Accounting Pronouncements In August 2016, the FASB issued ASU No. 2016-15, "Classification of Certain Cash Receipts and Cash Payments," which addresses eight classification issues related to the statement of cash flows. In November 2016, the FASB issued ASU 2016-18, "Statement of Cash Flows: Restricted Cash," which addresses classification and presentation of changes in restricted cash on the statement of cash flows. The standard requires that restricted cash and restricted cash equivalents be included as components of total cash and cash equivalents as presented on the statement of cash flows. The Company adopted ASU 2016-15 and ASU 2016-18 using a retrospective transition method effective January 1, 2018 and applied to the periods presented on the condensed consolidated statements of cash flows. Restricted cash includes cash and cash equivalents that is restricted through legal contracts, regulations or our intention to use the cash for a specific purpose. Our restricted cash primarily relates to refundable deposits and funds held in escrow. In May 2014, the FASB issued ASU 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. ASU 2014-09 will replace most of the existing revenue recognition guidance in U.S. GAAP when it becomes effective. This new accounting standard is effective for the Company for annual periods in fiscal years beginning after December 15, 2017 (as amended in August 2015 by ASU 2015-14, "Deferral of the Effective Date"). In December 27, 2016, FASB issued ASU 2016-20, "Technical Corrections and Improvements to Topic 606, Revenue from Contracts with Customers," which addresses loan guarantee fees, impairment testing of contract costs, provisions for losses on construction-type and production-type contracts, and various disclosures. ASU 2016-20 will go into effect once ASU 2014-09 takes effect. The Company adopted this standard effective January 1, 2018 using the modified retrospective method, which was only applied to contracts that were not completed as of the adoption date, with a cumulative adjustment to retained earnings.
