BASIS OF PRESENTATION	BASIS OF PRESENTATION Heska Corporation and its wholly-owned and majority-owned subsidiaries ("Heska", the "Company", "we" or "our") sell advanced veterinary diagnostic and other specialty veterinary products. Our offerings include blood testing instruments and supplies, digital imaging products, software and services, and single use products and services such as in-clinic heartworm diagnostic tests, heartworm preventive products, allergy immunotherapy products and allergy testing. Our core focus is on the canine and feline companion animal health markets. In the opinion of management, the accompanying unaudited Condensed Consolidated Financial Statements contain all adjustments, consisting of normal, recurring adjustments, necessary to present fairly the financial position of the Company at March 31, 2016, and the results of our operations and cash flows for the three months ended March 31, 2016 and 2015. The Condensed Consolidated Financial Statements included herein have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC"). Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("U.S. GAAP") have been condensed or omitted pursuant to such rules and regulations. These unaudited Condensed Consolidated Financial Statements should be read in conjunction with the audited Consolidated Financial Statements and Notes thereto contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2015 and other financial information filed with the SEC. 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, the 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. Significant estimates are required when establishing the allowance for doubtful accounts and the provision for excess or obsolete inventory, in determining the period over which our obligations are fulfilled under agreements to license product rights and/or technology rights, evaluating long-lived and intangible assets for impairment, determining the allocation of purchase price under purchase accounting, estimating the expense associated with the granting of stock options, determining the value of our non-controlling interest and in determining the need for, and the amount of, a valuation allowance on deferred tax assets. Critical Accounting Policies Our accounting policies are described in our audited Consolidated Financial Statements and Notes thereto contained in our Annual Report on Form 10-K for the year ended December 31, 2015. Recent Accounting Pronouncements In March 2016, the FASB issued guidance codified in Accounting Standards Codification (“ASC”) Topic 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting. The standard simplifies several aspects related to the accounting for share-based payment transactions, including the accounting for income taxes, statutory tax withholding requirements and classification on the statement of cash flows. The standard will be effective for the fiscal year beginning January 1, 2017 and subsequent interim periods. We are currently evaluating the impact the provisions of the Topic will have on our consolidated financial statements. In February 2016, the FASB issued ASU 2016-02, Leases, which supersedes ASC 840, Leases, and creates a new topic, ASC 842, Leases. This update requires lessees to recognize a lease liability and a lease asset for all leases, including operating leases, with a term greater than 12 months on its balance sheet. The update also expands the required quantitative and qualitative disclosures surrounding leases. This update is effective for fiscal years beginning after December 15, 2018 and interim periods within those fiscal years, with earlier application permitted. This update will be applied using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. We are currently evaluating the effect of this update on our consolidated financial statements. In November 2015, the FASB issued ASU 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes. The amendments in this update simplify the presentation of deferred income taxes and require that deferred tax liabilities and assets be classified as non-current in a classified statement of financial position. This update applies to all entities that present a classified statement of financial position. These amendments may be applied either prospectively to all deferred tax liabilities and assets or retrospectively to all periods presented. If the guidance is applied prospectively, disclosure is made in the first interim and first annual period of change, the nature of and reason for the change in accounting principle and a statement that prior periods were not retrospectively adjusted. If the guidance is applied retrospectively, disclosure is made in the first interim and first annual period of change, the nature of and reason for the change in accounting principle and quantitative information about the effects of the accounting change on prior periods. The amendments are effective for financial statements issued for annual periods beginning after December 15, 2016, and interim periods within those annual periods. Earlier application is permitted for all entities as of the beginning of an interim or annual reporting period. We have decided to early-adopt ASU 2015-17, which resulted in a retrospective adjustment of amounts disclosed in our consolidated balance sheet as of March 31, 2015. In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606). Upon the effective date, the ASU replaces almost all existing revenue recognition guidance, including industry specific guidance, in generally accepted accounting principles. In August 2015, the FASB issued ASU 2015-14, Revenue from Contracts with Customers (Topic 606): Deferral of the Effective Date. The amendments in this update deferred the effective date for implementation of ASU 2014-09 by one year and are now effective for annual reporting periods beginning after December 15, 2017. Early application is permitted only as of annual reporting periods beginning after December 15, 2016 including interim reporting periods within that period. We are currently assessing the impact that the adoption of this standard will have on our consolidated financial statements and related disclosures upon implementation.
