Summary of Significant Accounti

Summary of Significant Accounting Policies	9 Months Ended

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	1. Summary of Significant Accounting Policies Basis of Presentation These condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP"). The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The accompanying unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial reporting. In the opinion of management of the Company, the unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments necessary for a fair presentation. The results of operations for the three months ended September 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017 or for any other period. The financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2016 Annual Report on Form 10-K filed with the SEC on March 30, 2017 . During the third quarter of 2017, we identified and corrected an immaterial charge in the reported non-cash loss on debt extinguishment and interest expense recorded in the second quarter 2017 in our Condensed Consolidated Statements of Operations. The Fourth Amendment to the Company’s Credit Agreement should have been accounted for as a modification rather than an extinguishment in accordance with the accounting literature under ASC 470, Debt. The unaudited Consolidated Statements of Operations for the three months ended September 30, 2017, reflect a reversal of the immaterial non-cash net $1.4 million charge to loss on debt extinguishment and interest expense. This matter had no effect on the reported revenue, gross profit, or the Condensed Consolidated Statement of Cash Flows and had no material effect on the Condensed Consolidated Balance Sheet, or Condensed Consolidated Statements of Comprehensive Loss. See Note 6 - Debt for more information related to the Company’s Credit Agreement. Use of Estimates The preparation of the accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses. Significant items subject to such estimates include allowance for doubtful accounts, stock-based compensation, contingent consideration, acquired intangible assets, the useful lives of intangible assets and property and equipment, and income taxes. In accordance with GAAP, management bases its estimates on historical experience and on various other assumptions that management believes are reasonable under the circumstances. Management regularly evaluates its estimates and assumptions using historical experience and other factors; however, actual results could differ from those estimates. Concentrations of Credit Risk and Significant Customers Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents and accounts receivable. The Company’s cash and cash equivalents are placed with high-quality financial institutions, which, at times, may exceed federally insured limits. The Company has not experienced any losses in these accounts, and the Company does not believe it is exposed to any significant credit risk related to cash and cash equivalents. The Company provides credit, in the normal course of business, to a number of its customers. The Company performs periodic credit evaluations of its customers and generally does not require collateral. No individual customer represented more than 10% of total revenues in the three months ended September 30, 2017 or for the year ended December 31, 2016 , or more than 10% of accounts receivable as of September 30, 2017 or December 31, 2016 . Fair Value of Financial Instruments The Company’s financial instruments consist principally of cash and cash equivalents, accounts receivable, and accounts payable, and long–term debt. The carrying value of cash and cash equivalents, accounts receivable, and accounts payable approximate fair value, primarily due to short maturities. The carrying values of the Company’s debt instruments approximated their fair value based on rates currently available to the Company. Recent Accounting Pronouncements Recently issued accounting pronouncements not yet adopted In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09 (Topic 606), Revenue from Contracts with Customers. ASU 2014-09 amends the existing accounting standards for revenue recognition and is based on the principle that revenue should be recognized to depict the transfer of goods or services to a customer at an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The Company will adopt ASU 2014-09 on January 1, 2018, and we expect to use the modified retrospective application method. The Company has made significant progress in the assessment phase of this project but has not yet fully determined the impact of the new revenue recognition standard on its systems, processes and consolidated financial statements; however, we expect the new standard may have the most significant impact on the manner in which we account for certain costs to acquire new contracts (i.e., selling and commission costs). Generally, as it relates to these types of costs, the provisions of the new standard will result in the deferral of these costs on the consolidated balance sheets and subsequently amortizing these costs to the consolidated statements of income over the expected life of our customer relationships, which we have preliminarily estimated to be approximately 6 years. In February 2016, the FASB issued ASU 2016-02, Leases. The core change with ASU 2016-2 is the requirement for the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the effect that the adoption of ASU 2016-02 will have on its financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for losses. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted for annual and interim periods beginning after December 15, 2018. The Company is currently evaluating the effect that the adoption of ASU 2016-13 will have on its financial statements. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 is intended to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows and to eliminate the diversity in practice related to such classifications. The guidance in ASU 2016-15 is required for annual reporting periods beginning after December 15, 2017, with early adoption permitted. The Company does not expect the adoption of this guidance will have a material impact on its financial statements. In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which revises the definition of a business and assists in the evaluation of when a set of transferred assets and activities is a business. ASU 2017-01 is effective for interim and annual reporting periods beginning after December 15, 2017, and should be applied prospectively. Early adoption is permitted under certain circumstances. The Company does not expect the adoption of this guidance will have a material impact on its financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminates step two of the goodwill impairment test and specifies that goodwill impairment should be measured by comparing the fair value of a reporting unit with its carrying amount. Additionally, the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets should be disclosed. ASU 2017-04 is effective for annual or interim goodwill impairment tests performed in fiscal years beginning after December 15, 2019; early adoption is permitted. We currently anticipate that the adoption of ASU 2017-04 will not have a material impact on our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation: Scope of Modification Accounting, which provides guidance about which changes to the terms or conditions of a share-based payment awarded require an entity to apply modification accounting. ASU 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted. The amendments in ASU 2017-09 are to be applied prospectively to an award modified on or after the adoption date; consequently, the impact will be dependent on whether we modify any share-based payment awards and the nature of such modifications. The adoption of this standard is not expected to have a material impact on our financial statements. Recently adopted accounting pronouncements In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern: Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. The new standard provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. The Company adopted ASU 2014-15 during the first quarter of 2017. No additional disclosure was deemed necessary upon the adoption of ASU 2014-15. This standard would not result in an amount being recorded. In March 2016, the FASB issued ASU 2016-09, Stock Compensation. The core change with ASU 2016-09 is the simplification of several aspects of the accounting for share-based payment transactions, including the income tax consequences, classifications of awards as either equity or liabilities, and classification on the statement of cash flows. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. The Company adopted ASU 2016-09 during the first quarter of 2017. No impact on the financial statements was recorded as a result of the adoption of ASU 2016-09.

Acquisitions	2. Acquisitions 2017 Acquisitions On January 10, 2017, the Company completed its purchase of Omtool, Ltd ("Omtool"), a document capture, fax and workflow solution company. The purchase price consideration paid was approximately $19.3 million in cash payable at closing (net of $3.0 million of cash acquired). Revenues recorded since the acquisition date through September 30, 2017 were approximately $8.0 million . On April 21, 2017, the Company acquired RightAnswers, Inc.

The purchase price was $17.4 million , in cash at closing (net of $0.1 million cash acquired) and a $2.5 million cash holdback payable in one year (subject to indemnification claims) and excludes potential future earn-out payments tied to additional performance-based goals. Revenues recorded since the acquisition date through September 30, 2017 were approximately $3.4 million . On July 13, 2017, the Company acquired Waterfall International Inc. (“Waterfall”), a cloud-based mobile messaging platform. The purchase price consideration paid was approximately $24.4 million in cash at closing (net of $0.4 million of cash acquired) and a $1.5 million cash holdback payable in 18 months (subject to indemnification claims). The foregoing excludes additional potential $3.0 million in earnout payments tied to performance-based conditions. Revenues recorded since the acquisition date through September 30, 2017 were approximately $2.6 million . 2016 Acquisitions On January 7, 2016, the Company completed its purchase of LeadLander, Inc. ("LeadLander"), a website analytics provider. The purchase price consideration paid was approximately $8.0 million in cash payable at closing (net of $0.4 million of cash acquired) and a $1.2 million cash holdback payable in 12 months (subject to indemnification claims), which was fully paid after December 31, 2016. In addition, the Asset Purchase Agreement included a contingent share consideration component pursuant to which the Company issued an aggregate of $2.4 million in common stock on July 25, 2016. On March 14, 2016, the Company completed its purchase of HipCricket, Inc. ("HipCricket"), a cloud-based mobile messaging software provider. The consideration paid to the seller consisted of the issuance of one million shares of the Company's common stock and the transfer of the Company's EPM Live product business. The value of the shares on the closing date of the transaction was approximately $5.7 million , and the fair value of the EPM Live product business was approximately $5.9 million . At the time of the acquisition, the Company recognized a loss on the transfer in conjunction with the EPM Live net asset value of approximately $0.7 million in other expenses, net. Prior to the transaction, HipCricket was owned by an affiliate of ESW Capital, LLC, which is a shareholder of the Company. Raymond James & Co. provided a fairness opinion to the Company in connection with the transaction. On April 27, 2016, the Company acquired Advanced Processing & Imaging, Inc. ("API"), a content management platform driving workflow in governments and schools. The purchase price consideration consisted of $4.1 million in cash payable at closing (net of $0.1 million of cash acquired), and a $0.8 million cash holdback payable in 12 months (subject to indemnification claims). The following condensed table presents the preliminary and finalized acquisition-date fair value of the assets acquired and liabilities assumed for the acquisitions in 2016 and through the nine months ended September 30, 2017 , as well as assets and liabilities (in thousands): Preliminary Finalized Waterfall RightAnswers Omtool API HipCricket LeadLander Year Acquired 2017 2017 2017 2016 2016 2016 Cash $ 435 $ 139 $ 2,957 $ 125 $ — $ 365 Accounts receivable 1,442 2,164 784 821 1,226 199 Other current assets 1,031 125 607 54 273 55 Property and equipment 74 158 63 68 — 5 Customer relationships 5,700 5,700 4,400 1,420 1,000 970 Trade name 110 200 170 40 70 70 Technology 2,800 2,600 3,180 810 900 1,410 Goodwill 18,747 20,100 13,933 3,420 8,531 13,104 Other assets — — 33 89 — 6 Total assets acquired 30,339 31,186 26,127 6,847 12,000 16,184 Accounts payable (605 ) (139 ) (219 ) (11 ) (44 ) — Accrued expense and other (1,382 ) (1,321 ) (915 ) (137 ) — (254 ) Deferred revenue (1,220 ) (5,428 ) (2,779 ) (1,699 ) (356 ) (910 ) Total liabilities assumed (3,207 ) (6,888 ) (3,913 ) (1,847 ) (400 ) (1,164 ) Total consideration $ 27,132 $ 24,298 $ 22,214 $ 5,000 $ 11,600 $ 15,020 Tangible assets were valued at their respective carrying amounts, which approximates their estimated fair value. The valuation of identifiable intangible assets reflects management’s estimates based on, among other factors, use of established valuation methods. Customer relationships were valued using an income approach, which estimates fair value based on the earnings and cash flow capacity of the subject asset. The value of the marketing-related intangibles was determined using a relief-from-royalty method, which estimates fair value based on the value the owner of the asset receives from not having to pay a royalty to use the asset. Developed technology was valued using a cost-to-recreate approach. The Company recorded the purchase of the acquisitions described above using the acquisition method of accounting and, accordingly, recognized the assets acquired and liabilities assumed at their fair values as of the date of the acquisition. The purchase price allocations for the 2017 acquisitions of Omtool, RightAnswers, and Waterfall are preliminary as the Company has not obtained and evaluated all of the detailed information necessary to finalize the opening balance sheet amounts in all respects. The purchase price allocations for the 2016 acquisitions of Leadlander, HipCricket, and API are final. Management has recorded the purchase price allocations based upon acquired company information that is currently available. Management expects to close its purchase price allocations for Omtool and RightAnswers during the last quarter of 2017 and during the first half of 2018 for Waterfall. The goodwill of $77.8 million for the above acquisitions is primarily attributable to the synergies expected to arise after the acquisition. Goodwill ded uctible for tax purposes is $11.6 million for the LeadLander acquisition, $8.2 million for HipCricket, and $3.7 million for Waterfall. There was no goodwill deductible for tax purposes for the API, Omtool, and RightAnswers acquisitions.

Fair Value Measurements

Fair Value Disclosures [Abstract]
Fair Value Measurements	3. Fair Value Measurements Fair value is defined as the exit price, or the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants as of the measurement date. GAAP sets forth a three–tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The three tiers are Level 1, defined as observable inputs, such as quoted market prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, which therefore requires an entity to develop its own assumptions. Changes to the fair value of earnout liabilities are recorded to other expense, net. Lia bilities measured at fair value on a recurring basis are summarized below (in thousands): Fair Value Measurements at December 31, 2016 Level 1 Level 2 Level 3 Total Earnout consideration liability $ — $ — $ 2,500 $ 2,500 Fair Value Measurements at September 30, 2017 (unaudited) Level 1 Level 2 Level 3 Total Earnout consideration liability $ — $ — $ 4,193 $ 4,193 The Level 3 earnout consideration liability consists of amounts associated with the acquisitions of LeadLander in January 2016, RightAnswers in April 2017, and Waterfall in July 2017.

Income Taxes	5. Income Taxes The Company’s income tax provision for the three and nine months ended September 30, 2017 and September 30, 2016 reflects its estimate of the effective tax rates expected to be applicable for the full years, adjusted for any discrete events that are recorded in the period in which they occur. The estimates are re-evaluated each quarter based on the estimated tax expense for the full year. The tax provision for the three and nine months ended September 30, 2017 and September 30, 2016 is primarily related to foreign income taxes associated with our Canadian operations, changes in deferred tax liabilities associated with amortization of United States tax deductible goodwill and state taxes in certain states in which the Company does not file on a consolidated basis or have net operating loss carryforwards. The Company has historically incurred operating losses in the United States and, given its cumulative losses and limited history of profits, has recorded a valuation allowance against its United States net deferred tax assets, exclusive of tax deductible goodwill, at September 30, 2017 and September 30, 2016 , respectively. The Company has reflected any uncertain tax positions within its current taxes payable, but none in deferred taxes. Federal, state, and foreign income tax returns have been filed in jurisdictions with varying statutes of limitations. Varying among the separate companies, tax years 1998 through 2016 remain subject to examination by federal and most state tax authorities due to our net operating loss carryforwards. In foreign jurisdictions, tax years 2008 through 2016 remain subject to examination. The Company increased both its net operating loss deferred tax asset and its valuation allowance by $152,000 upon adoption of ASU 2016-09 relating to certain tax deductions associated with stock option transactions greater than the stock-related compensation expense for financial statement purposes.

Summary of Significant Accoun18

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2017
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation These condensed consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States ("GAAP"). The condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. The accompanying unaudited interim condensed consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission ("SEC") for interim financial reporting. In the opinion of management of the Company, the unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements and include all adjustments necessary for a fair presentation. The results of operations for the three months ended September 30, 2017 are not necessarily indicative of the results to be expected for the year ending December 31, 2017 or for any other period. The financial statements should be read in conjunction with the consolidated financial statements and notes thereto included in the Company’s 2016 Annual Report on Form 10-K filed with the SEC on March 30, 2017 .
Use of Estimates	Use of Estimates The preparation of the accompanying condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the consolidated financial statements, and the reported amounts of revenues and expenses. Significant items subject to such estimates include allowance for doubtful accounts, stock-based compensation, contingent consideration, acquired intangible assets, the useful lives of intangible assets and property and equipment, and income taxes. In accordance with GAAP, management bases its estimates on historical experience and on various other assumptions that management believes are reasonable under the circumstances. Management regularly evaluates its estimates and assumptions using historical experience and other factors; however, actual results could differ from those estimates.
Concentrations of Credit Risk and Significant Customers	Concentrations of Credit Risk and Significant Customers Financial instruments that potentially subject the Company to credit risk consist of cash and cash equivalents and accounts receivable. The Company’s cash and cash equivalents are placed with high-quality financial institutions, which, at times, may exceed federally insured limits. The Company has not experienced any losses in these accounts, and the Company does not believe it is exposed to any significant credit risk related to cash and cash equivalents. The Company provides credit, in the normal course of business, to a number of its customers. The Company performs periodic credit evaluations of its customers and generally does not require collateral. No individual customer represented more than 10% of total revenues in the three months ended September 30, 2017 or for the year ended December 31, 2016 , or more than 10% of accounts receivable as of September 30, 2017 or December 31, 2016 .
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company’s financial instruments consist principally of cash and cash equivalents, accounts receivable, and accounts payable, and long–term debt. The carrying value of cash and cash equivalents, accounts receivable, and accounts payable approximate fair value, primarily due to short maturities. The carrying values of the Company’s debt instruments approximated their fair value based on rates currently available to the Company.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently issued accounting pronouncements not yet adopted In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2014-09 (Topic 606), Revenue from Contracts with Customers. ASU 2014-09 amends the existing accounting standards for revenue recognition and is based on the principle that revenue should be recognized to depict the transfer of goods or services to a customer at an amount that reflects the consideration a company expects to receive in exchange for those goods or services. The Company will adopt ASU 2014-09 on January 1, 2018, and we expect to use the modified retrospective application method. The Company has made significant progress in the assessment phase of this project but has not yet fully determined the impact of the new revenue recognition standard on its systems, processes and consolidated financial statements; however, we expect the new standard may have the most significant impact on the manner in which we account for certain costs to acquire new contracts (i.e., selling and commission costs). Generally, as it relates to these types of costs, the provisions of the new standard will result in the deferral of these costs on the consolidated balance sheets and subsequently amortizing these costs to the consolidated statements of income over the expected life of our customer relationships, which we have preliminarily estimated to be approximately 6 years. In February 2016, the FASB issued ASU 2016-02, Leases. The core change with ASU 2016-2 is the requirement for the recognition of lease assets and lease liabilities by lessees for those leases classified as operating leases under previous GAAP. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018, with early adoption permitted. The Company is currently evaluating the effect that the adoption of ASU 2016-02 will have on its financial statements. In June 2016, the FASB issued ASU 2016-13, Financial Instruments - Credit Losses: Measurement of Credit Losses on Financial Instruments, which changes the impairment model for most financial assets. The new model uses a forward-looking expected loss method, which will generally result in earlier recognition of allowances for losses. ASU 2016-13 is effective for annual and interim periods beginning after December 15, 2019 and early adoption is permitted for annual and interim periods beginning after December 15, 2018. The Company is currently evaluating the effect that the adoption of ASU 2016-13 will have on its financial statements. In August 2016, the FASB issued ASU 2016-15, Classification of Certain Cash Receipts and Cash Payments. ASU 2016-15 is intended to add or clarify guidance on the classification of certain cash receipts and payments in the statement of cash flows and to eliminate the diversity in practice related to such classifications. The guidance in ASU 2016-15 is required for annual reporting periods beginning after December 15, 2017, with early adoption permitted. The Company does not expect the adoption of this guidance will have a material impact on its financial statements. In January 2017, the FASB issued ASU 2017-01, Clarifying the Definition of a Business, which revises the definition of a business and assists in the evaluation of when a set of transferred assets and activities is a business. ASU 2017-01 is effective for interim and annual reporting periods beginning after December 15, 2017, and should be applied prospectively. Early adoption is permitted under certain circumstances. The Company does not expect the adoption of this guidance will have a material impact on its financial statements. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other: Simplifying the Test for Goodwill Impairment. ASU 2017-04 eliminates step two of the goodwill impairment test and specifies that goodwill impairment should be measured by comparing the fair value of a reporting unit with its carrying amount. Additionally, the amount of goodwill allocated to each reporting unit with a zero or negative carrying amount of net assets should be disclosed. ASU 2017-04 is effective for annual or interim goodwill impairment tests performed in fiscal years beginning after December 15, 2019; early adoption is permitted. We currently anticipate that the adoption of ASU 2017-04 will not have a material impact on our consolidated financial statements. In May 2017, the FASB issued ASU 2017-09, Compensation - Stock Compensation: Scope of Modification Accounting, which provides guidance about which changes to the terms or conditions of a share-based payment awarded require an entity to apply modification accounting. ASU 2017-09 is effective for interim and annual reporting periods beginning after December 15, 2017, with early adoption permitted. The amendments in ASU 2017-09 are to be applied prospectively to an award modified on or after the adoption date; consequently, the impact will be dependent on whether we modify any share-based payment awards and the nature of such modifications. The adoption of this standard is not expected to have a material impact on our financial statements. Recently adopted accounting pronouncements In August 2014, the FASB issued ASU 2014-15, Presentation of Financial Statements - Going Concern: Disclosure of Uncertainties about an Entity's Ability to Continue as a Going Concern. The new standard provides guidance around management's responsibility to evaluate whether there is substantial doubt about an entity's ability to continue as a going concern and to provide related footnote disclosures. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. The Company adopted ASU 2014-15 during the first quarter of 2017. No additional disclosure was deemed necessary upon the adoption of ASU 2014-15. This standard would not result in an amount being recorded. In March 2016, the FASB issued ASU 2016-09, Stock Compensation. The core change with ASU 2016-09 is the simplification of several aspects of the accounting for share-based payment transactions, including the income tax consequences, classifications of awards as either equity or liabilities, and classification on the statement of cash flows. The new standard is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. The Company adopted ASU 2016-09 during the first quarter of 2017. No impact on the financial statements was recorded as a result of the adoption of ASU 2016-09.
