Accounting Policies [Abstract] |
Ownership, Description of Business, and Summary of Significant Accounting Policies | Ownership, Description of Business, and Summary of Significant Accounting Policies Encore Capital Group, Inc. (“Encore”), through its subsidiaries (collectively with Encore, the “Company”), is an international specialty finance company providing debt recovery solutions and other related services for consumers across a broad range of financial assets. The Company purchases portfolios of defaulted consumer receivables at deep discounts to face value and manages them by working with individuals as they repay their obligations and work toward financial recovery. Defaulted receivables are consumers’ unpaid financial commitments to credit originators, including banks, credit unions, consumer finance companies, commercial retailers, and telecommunication companies. Defaulted receivables may also include receivables subject to bankruptcy proceedings. Basis of Consolidation The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“GAAP”), and reflect the accounts and operations of the Company and those of its subsidiaries in which the Company has a controlling financial interest. The Company also consolidates VIEs, for which it is the primary beneficiary. The primary beneficiary has both (a) the power to direct the activities of the VIE that most significantly affect the entity’s economic performance and (b) either the obligation to absorb losses or the right to receive benefits. Refer to Note 10, “Variable Interest Entities” for further details. All intercompany transactions and balances have been eliminated in consolidation. Translation of Foreign Currencies The financial statements of certain of the Company’s foreign subsidiaries are measured using their local currency as the functional currency. Assets and liabilities of foreign operations are translated into U.S. dollars using period-end exchange rates, and revenues and expenses are translated into U.S. dollars using average exchange rates in effect during each period. The resulting translation adjustments are recorded as a component of other comprehensive income or loss. Equity accounts are translated at historical rates, except for the change in retained earnings during the year which is the result of the income statement translation process. Intercompany transaction gains or losses at each period end arising from subsequent measurement of balances for which settlement is not planned or anticipated in the foreseeable future are included as translation adjustments and recorded within other comprehensive income or loss. Translation gains or losses are the material components of accumulated other comprehensive income or loss. Transaction gains and losses are included in other income or expense. Reclassifications Certain immaterial reclassifications have been made to the consolidated financial statements to conform to the current year’s presentation. Change in Accounting Principle In February 2018, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). ASU 2018-02 is effective for all entities for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2018. Early adoption is permitted either (1) in the period of adoption or (2) retrospectively to each period in which the effect of the change in the federal income tax rate in the Tax Cuts and Jobs Act is recognized. The Company early adopted this guidance for the year ending December 31, 2017. The Company elected to reclassify the income tax effects of the Tax Cuts and Jobs Act from accumulated other comprehensive income to retained earnings in the period of adoption using the security by security approach. The adoption of ASU 2018-02 resulted in a reclassification of $0.3 million due to tax rate changes for certain hedge instruments from accumulated other comprehensive income to accumulated earnings. In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting (“ASU 2016-09”). ASU 2016-09 simplifies several aspects of the accounting for share-based payment transactions, including the income tax consequences, classification of awards as either equity or liabilities, and classification on the statement of cash flows. For public entities, ASU 2016-09 is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. Early adoption is permitted. Upon adoption of this standard, excess tax benefits and tax deficiencies will be recognized as income tax expense, and the tax effects of exercised or vested awards will be treated as discrete items in the period in which they occur. As such, implementation of this standard could create volatility in an entity’s effective income tax rate on a quarter by quarter basis. The volatility in the effective income tax rate is due primarily to fluctuations in the stock price and the timing of stock option exercises and vesting of restricted share grants. The standard also requires excess tax benefits to be presented as an operating activity on the statement of cash flows rather than as a financing activity. An entity may elect to apply the change in presentation in the statement of cash flows either prospectively or retrospectively to all periods presented. Further, the amendments allow an entity to make an accounting policy election to either estimate forfeitures or recognize forfeitures as they occur. If an election is made, the change to recognize forfeitures as they occur must be adopted using a modified retrospective approach with a cumulative effect adjustment recorded to opening retained earnings. ASU 2016-09 became effective for the Company on January 1, 2017. The Company applied the change in presentation to the statement of cash flows retrospectively for all periods presented after adoption date. The Company believes that the new standard may cause volatility in its effective tax rates and earnings per share due to the tax effects related to share-based payments being recorded to the income statement. The volatility in future periods will depend on the Company’s stock price at the awards’ vest dates and the number of awards that vest in each period. The Company will not elect an accounting policy change to record forfeitures as they occur and will continue to estimate forfeitures at each period. Recent Accounting Pronouncements Other than the adoption of ASU 2016-09 as discussed in the “Change in Accounting Principle” section above, there have been no new accounting pronouncements made effective during year ended December 31, 2017 that have significance, or potential significance, to the Company’s consolidated financial statements. Recent Accounting Pronouncements Not Yet Effective In August 2017, the FASB issued ASU No. 2017-12, Targeted Improvements to Accounting for Hedging Activities—Derivatives and Hedging (Topic 815) (“ASU 2017-12”) which amends the hedge accounting recognition and presentation requirements in Accounting Standards Codification (“ASC”) 815. ASU 2017-12 improves Topic 815 Derivatives and Hedging by simplifying and expanding the eligible hedging strategies for financial and nonfinancial risks by more closely aligning hedge accounting with a company’s risk management activities, and also simplifies its application through targeted improvements in key practice areas. This includes expanding the list of items eligible to be hedged and amending the methods used to measure the effectiveness of hedging relationships. In addition, the ASU prescribes how hedging results should be presented and requires incremental disclosures. These changes are intended to allow preparers more flexibility and to enhance the transparency of how hedging results are presented and disclosed. Further, the new standard provides partial relief on the timing of certain aspects of hedge documentation and eliminates the requirement to recognize hedge ineffectiveness separately in earnings in the current period. The ASU is effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted, including adoption in any interim period. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements as well as whether to adopt the new guidance early. In May 2017, the FASB issued ASU No. 2017-09, Compensation—Stock Compensation (Topic 718) (“ASU 2017-09”). ASU 2017-09 provides clarity in order to reduce both (1) diversity in practice and (2) cost and complexity when applying the guidance in Topic 718, Compensation—Stock Compensation, to a change to the terms or conditions of a share-based payment award. Under the new guidance, modification accounting is required only if the fair value, the vesting conditions, or the classification of the award (as equity or liability) changes as a result of the change in terms or conditions. The guidance is effective for annual periods, and interim periods within those annual periods, beginning after December 15, 2017. Early adoption is permitted, including adoption in any interim period. The Company does not anticipate that the adoption of ASU 2017-09 will have a material impact on its consolidated financial statements and related disclosures. In January 2017, the FASB issued ASU 2017-04, Intangibles - Goodwill and Other (Topic 350). The amendments in this update simplify the test for goodwill impairment by eliminating Step 2 from the impairment test, which required the entity to perform procedures to determine the fair value at the impairment testing date of its assets and liabilities following the procedure that would be required in determining fair value of assets acquired and liabilities assumed in a business combination. The amendments in this update are effective for public companies for annual or any interim goodwill impairments tests in fiscal years beginning after December 15, 2019. Early adoption is permitted for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company did not early adopt this guidance for its annual goodwill impairment testing on October 1, 2017. In January 2017, the FASB issued ASU 2017-01, Business Combinations (Topic 805); Clarifying the Definition of a Business. The amendments in this update clarify the definition of a business to help companies evaluate whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The amendments in this update are effective for public companies for annual periods beginning after December 15, 2017, including interim periods within those periods. The Company is evaluating the impact of adopting this guidance on its consolidated financial statements. In August 2016, the FASB issued ASU 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments (“ASU 2016-15”). The FASB issued ASU 2016-15 to decrease the diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. The amendments in this update provide guidance on eight specific cash flow issues. ASU 2016-15 is effective for reporting periods beginning after December 15, 2017, with early adoption permitted, provided that all of the amendments are adopted in the same period. The guidance requires application using a retrospective transition method. The Company will adopt the guidance of ASU 2016-15 in the first quarter of 2018. In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments (“ASU 2016-13”). ASU 2016-13 applies a current expected credit loss model which is a new impairment model based on expected losses rather than incurred losses. Under this model, an entity would recognize an impairment allowance equal to its current estimate of all contractual cash flows that the entity does not expect to collect from financial assets measured at amortized cost. The estimate of expected credit losses should consider historical information, current information, as well as reasonable and supportable forecasts, including estimates of prepayments. The expected credit losses, and subsequent adjustments to such losses, will be recorded through an allowance account that is deducted from the amortized cost basis of the financial asset, with the net carrying value of the financial asset presented on the consolidated balance sheet at the amount expected to be collected. ASU 2016-13 eliminates the current accounting model for loans and debt securities acquired with deteriorated credit quality under ASC 310-30, which provides authoritative guidance for the accounting of the Company’s investment in receivable portfolios. Under this new standard, entities will gross up the initial amortized cost for the purchased financial assets with credit deterioration (“PCD assets”), the initial amortized cost will be the sum of (1) the purchase price and (2) the estimate of credit losses as of the date of acquisition. After initial recognition of PCD assets and the related allowance, any change in estimated cash flows (favorable or unfavorable) will be immediately recognized in the income statement because the yield on PCD assets would be locked. ASU 2016-13 is effective for reporting periods beginning after December 15, 2019 with early adoption permitted for reporting periods beginning after December 15, 2018. The guidance will be applied on a modified retrospective basis through a cumulative-effect adjustment to retained earnings as of the beginning of the period in which ASU 2016-13 is adopted. However, the FASB has determined that financial assets for which the guidance in Subtopic 310-30, Receivables-Loans and Debt Securities Acquired with Deteriorated Credit Quality, has previously been applied should prospectively apply the guidance in ASU 2016-13 for PCD assets. A prospective transition approach should be used for PCD assets where upon adoption, the amortized cost basis should be adjusted to reflect the addition of the allowance for credit losses. This transition relief will avoid the need for a reporting entity to reassess its purchased financial assets that exist as of the date of adoption to determine whether they would have met at acquisition the new criteria of more-than insignificant credit deterioration since origination. The transition relief also will allow an entity to accrete the remaining noncredit discount (based on the revised amortized cost basis) into interest income at the effective interest rate at the adoption date of ASU 2016-13. The same transition requirements should be applied to beneficial interests that previously applied Subtopic 310-30 or have a significant difference between contractual cash flows and expected cash flows. The Company is in the process of determining the effects the adoption will have on its consolidated financial statements as well as whether to adopt the new guidance early. In February 2016, the FASB issued ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”). ASU 2016-02 changes accounting for leases and requires lessees to recognize the assets and liabilities arising from all leases, including those classified as operating leases under previous accounting guidance, on the balance sheet and requires disclosure of key information about leasing arrangements to increase transparency and comparability among organizations. The new guidance must be adopted using the modified retrospective approach and will be effective for the Company starting in the first quarter of fiscal year 2019. Early adoption is permitted. The Company is in the process of determining the effects the adoption will have on its consolidated financial statements as well as whether to adopt the new guidance early. In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”). The objective of ASU 2014-09 is to establish a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and will supersede most of the existing revenue recognition guidance, including industry-specific guidance. The core principle is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In applying ASU 2014-09, companies will perform a five-step analysis of transactions to determine when and how revenue is recognized. ASU 2014-09 applies to all contracts with customers except those that are within the scope of other topics in the FASB’s ASC. ASU 2014-09 is effective for annual reporting periods (including interim periods within that reporting period) beginning after December 15, 2016 and shall be applied using either a full retrospective or modified retrospective approach. Early application is not permitted. In August 2015, FASB issued ASU 2015-14, which defers the effective date of ASU 2014-09 for all public companies for all annual periods beginning after December 15, 2017 with early adoption permitted only as of annual reporting periods beginning after December 31, 2016, including interim periods within the reporting period. In March 2016, the FASB issued ASU 2016-08 as an amendment to ASU 2014-09, which clarifies how to identify the unit of accounting for the principal versus agent evaluation, how to apply the control principle to certain types of arrangements, such as service transactions, and reframed the indicators in the guidance to focus on evidence that an entity is acting as a principal rather than as an agent. The Company’s investment in receivable portfolios is outside of the scope of Topic 606 since it is accounted for in accordance with ASC 310-30. The Company will adopt the new standard effective January 1, 2018, using the modified retrospective approach. As the majority of the Company’s revenues are not subject to the new guidance, the adoption of ASU 2014-09 will not have a material impact on the Company’s consolidated financial statements. With the exception of the updated standards discussed above, there have been no new accounting pronouncements not yet effective that have significance, or potential significance, to the Company’s consolidated financial statements. Use of Estimates The preparation of financial statements, in conformity with GAAP, requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and 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 materially differ from those estimates. Cash and Cash Equivalents Cash and cash equivalents consist of highly liquid investments with maturities of three months or less at the date of purchase. The Company invests its excess cash in bank deposits and money market instruments, which are afforded the highest ratings by nationally recognized rating firms. The carrying amounts reported in the consolidated statements of financial condition for cash and cash equivalents approximate their fair value. Included in cash and cash equivalents are cash collected on behalf of and due to third party clients. A corresponding balance is included in accounts payable and accrued liabilities. The balance of cash held for clients was $21.0 million and $15.1 million at December 31, 2017 and 2016, respectively. Investment in Receivable Portfolios In accordance with the authoritative guidance for loans and debt securities acquired with deteriorated credit quality, discrete receivable portfolio purchases during the same fiscal quarter are aggregated into pools based on common risk characteristics. Common risk characteristics include risk ratings (e.g. FICO or similar scores), financial asset type, collateral type, size, interest rate, date of origination, term, and geographic location. The Company’s static pools are typically grouped into credit card, purchased consumer bankruptcy, and mortgage portfolios. The Company further groups these static pools by geographic region or location. Portfolios acquired in business combinations are also grouped into these pools. During any fiscal quarter in which the Company has an acquisition of an entity that has portfolio, the entire historical portfolio of the acquired company is aggregated into the pool groups for that quarter, based on common characteristics, resulting in pools for that quarter that may consist of several different vintages of portfolio. Once a static pool is established, the portfolios are permanently assigned to the pool. The discount (i.e., the difference between the cost of each static pool and the related aggregate contractual receivable balance) is not recorded because the Company expects to collect a relatively small percentage of each static pool’s contractual receivable balance. As a result, receivable portfolios are recorded at cost at the time of acquisition. The purchase cost of the portfolios includes certain fees paid to third parties incurred in connection with the direct acquisition of the receivable portfolios. In compliance with the authoritative guidance, the Company accounts for its investments in receivable portfolios using either the interest method or the cost recovery method. The interest method applies an internal rate of return (“IRR”) to the cost basis of the pool, which remains unchanged throughout the life of the pool, unless there is an increase in subsequent expected cash flows. Subsequent increases in expected cash flows are recognized prospectively through an upward adjustment of the pool’s IRR over its remaining life. Subsequent decreases in expected cash flows do not change the IRR, but are recognized as an allowance to the cost basis of the pool, and are reflected in the consolidated statements of income as a reduction in revenue, with a corresponding valuation allowance, offsetting the investment in receivable portfolios in the consolidated statements of financial condition. With gross collections being discounted at monthly IRRs, when collections are lower in the near term, even if substantially higher collections are expected later in the collection curve, an allowance charge could result. The Company accounts for each static pool as a unit for the economic life of the pool (similar to one loan) for recognition of revenue from receivable portfolios, for collections applied to the cost basis of receivable portfolios and for provision for loss or allowance. Revenue from receivable portfolios is accrued based on each pool’s IRR applied to each pool’s adjusted cost basis. The cost basis of each pool is increased by revenue earned and portfolio allowance reversals and decreased by gross collections and portfolio allowances. If the amount and timing of future cash collections on a pool of receivables are not reasonably estimable, the Company accounts for such portfolios on the cost recovery method Cost Recovery Portfolios. The accounts in these portfolios have different risk characteristics than those included in other portfolios acquired during the same quarter, or the necessary information was not available to estimate future cash flows and, accordingly, they were not aggregated with other portfolios. Under the cost recovery method of accounting, no revenue is recognized until the carrying value of a Cost Recovery Portfolio has been fully recovered. See Note 5, “Investment in Receivable Portfolios, Net” for further discussion of investment in receivable portfolios. Fee-based Income Certain of the Company’s international subsidiaries earn fee-based income by providing portfolio management services to credit originators for non-performing loans. The Company recognizes fee-based income in accordance with the authoritative guidance for revenue recognition, specifically principal agent considerations. The revenue recognition guidance requires an analysis to be completed to determine if certain revenues should be reported gross or reported net of their related operating expense. This analysis includes an assessment of who retains credit risk, controls vendor selection, establishes pricing and remains the primary obligor on the transaction. The Company considers each of these factors to determine the correct method of recognizing fee-based income. Fee-based income is included in “Other Revenues” in the Company’s consolidated statements of operations. Goodwill and Other Intangible Assets Goodwill represents the excess of purchase price over the value assigned to the tangible and identifiable intangible assets, liabilities assumed, and noncontrolling interest of businesses acquired. Acquired intangible assets other than goodwill are amortized over their useful lives unless the lives are determined to be indefinite. In accordance with authoritative guidance on goodwill and other intangible assets, goodwill and other indefinite-lived intangible assets are tested at the reporting unit level annually for impairment and in interim periods if certain events occur indicating the fair value of a reporting unit may be below its carrying value. See Note 15, “Goodwill and Identifiable Intangible Assets” for further discussion of the Company’s goodwill and other intangible assets. Property and Equipment Property and equipment are recorded at cost, less accumulated depreciation and amortization. The provision for depreciation and amortization is computed using the straight-line method over the estimated useful lives of the assets as follows:
Fixed Asset Category |  | Estimated Useful Life
Leasehold improvements |  | Lesser of lease term, including periods covered by renewal options, or useful life
Furniture, fixtures and equipment |  | 5 to 10 years
Computer hardware and software |  | 3 to 5 years
Maintenance and repairs are charged to expense in the year incurred. Expenditures for major renewals that extend the useful lives of fixed assets are capitalized and depreciated over the useful lives of such assets. Deferred Court Costs The Company pursues legal collections using a network of attorneys that specialize in collection matters and through its internal legal channel. The Company generally pursues collections through legal means only when it believes a consumer has sufficient assets to repay their indebtedness but has, to date, been unwilling to pay. In order to pursue legal collections the Company is required to pay certain upfront costs to the applicable courts that are recoverable from the consumer (“Deferred Court Costs”). The Company capitalizes Deferred Court Costs in its consolidated financial statements and provides a reserve for those costs that it believes will ultimately be uncollectible. The Company determines the reserve based on an estimated court cost recovery rate established based on its analysis of historical court costs recovery data. The Company estimates deferral periods for Deferred Court Costs based on jurisdiction and nature of litigation and writes off any Deferred Court Costs not recovered within the respective deferral period. Collections received from debtors are first applied against related court costs with the balance applied to the debtors’ account balance. See Note 6, “Deferred Court Costs, Net” for further discussion. Income Taxes The Company uses the liability method of accounting for income taxes in accordance with the authoritative guidance for Income Taxes. When the Company prepares its consolidated financial statements, it estimates income taxes based on the various jurisdictions and countries where it conducts business. This requires the Company to estimate current tax exposure and to assess temporary differences that result from differing treatments of certain items for tax and accounting purposes. Deferred income taxes are recognized based on the differences between the financial statement and income tax bases of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The Company then assesses the likelihood that deferred tax assets will be realized. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. When the Company establishes a valuation allowance or increases this allowance in an accounting period, it records a corresponding tax expense in the consolidated statement of income. The Company includes interest and penalties related to income taxes within its provision for income taxes. See Note 12, “Income Taxes” for further discussion. Management must make significant judgments to determine the provision for income taxes, deferred tax assets and liabilities, and any valuation allowance to be recorded against deferred tax assets. Stock-Based Compensation The Company determines stock-based compensation expense for all share-based payment awards based on the measurement date fair value. The Company has certain share awards that include market conditions that affect vesting, the fair value of these shares is estimated using a lattice model. Compensation cost is not adjusted if the market condition is not met, as long as the requisite service is provided. For share awards that require service and performance conditions, the Company recognizes compensation cost only for those awards expected to meet the service and performance vesting conditions over the requisite service period of the award. Forfeiture rates are estimated based on the Company’s historical experience. See Note 11, “Stock-Based Compensation” for further discussion. Derivative Instruments and Hedging Activities The Company recognizes all derivative financial instruments in its consolidated financial statements at fair value. Changes in the fair value of derivative instruments are recorded in earnings unless hedge accounting criteria are met. The Company designates certain derivative instruments as cash flow hedges. The effective portion of the changes in fair value of these cash flow hedges is recorded each period, net of tax, in accumulated other comprehensive income or loss until the related hedged transaction occurs. Any ineffective portion of the changes in fair value of these cash flow hedges is recorded in earnings. In the event the hedged cash flow does not occur, or it becomes probable that it will not occur, the Company would reclassify the amount of any gain or loss on the related cash flow hedge to income or expense at that time. See Note 4, “Derivatives and Hedging Instruments” for further discussion. Redeemable Noncontrolling Interest Some minority shareholders in certain subsidiaries of the Company have the right, at certain times, to require the Company to acquire their ownership interest in those entities at fair value, and in some cases, to force a sale of the subsidiary if the Company chooses not to purchase their interests at fair value. The noncontrolling interest subject to these arrangements is included in temporary equity as redeemable noncontrolling interest, and is adjusted to its estimated redemption amount each reporting period. Future reductions in the carrying amount are subject to a “floor” amount that is equal to the fair value of the redeemable noncontrolling interest at the time it was originally recorded. The recorded value of the redeemable noncontrolling interest cannot go below the floor level. Adjustments to the carrying amount of redeemable noncontrolling interest are charged to retained earnings (or to additional paid-in capital if there are no retained earnings) and do not affect net income or comprehensive income in the consolidated financial statements. Earnings Per Share Basic earnings per share is calculated by dividing net earnings attributable to Encore by the weighted average number of shares of common stock outstanding during the period. Diluted earnings per share is calculated on the basis of the weighted average number of shares of common stock plus the effect of dilutive potential common shares outstanding during the period using the treasury stock method. Dilutive potential common shares include outstanding stock options, restricted stock, and the dilutive effect of the convertible senior notes. On April 24, 2014, the Company’s Board of Directors approved a $50.0 million share repurchase program. In May 2014, the Company repurchased 400,000 shares of its common stock for approximately $16.8 million. In May 2015, the Company repurchased 839,295 shares of common stock for approximately $33.2 million, which represented the remaining amount allowed under this share repurchase program. The Company’s practice is to retire the shares repurchased. On August 12, 2015, the Company’s Board of Directors approved a new $50.0 million share repurchase program. Repurchases under this program are expected to be made with cash on hand and may be made from time to time, subject to market conditions and other factors, in the open market, through private transactions, block transactions, or other methods as determined by the Company’s management and Board of Directors, and in accordance with market conditions, other corporate considerations, and applicable regulatory requirements. The program does not obligate the Company to acquire any particular amount of common stock, and it may be modified or suspended at any time at the Company’s discretion. As of December 31, 2017, we had not made any repurchases under the share repurchase program. A reconciliation of shares used in calculating earnings per basic and diluted shares follows (in thousands):
| Year Ended December 31,
| 2017 |  | 2016 |  | 2015
Weighted average common shares outstanding—basic | 25,972 |  |  | 25,713 |  |  | 25,722 |
Dilutive effect of stock-based awards | 255 |  |  | 196 |  |  | 253 |
Dilutive effect of convertible senior notes | 178 |  |  | — |  |  | 672 |
Weighted average common shares outstanding—diluted | 26,405 |  |  | 25,909 |  |  | 26,647 |
Anti-dilutive employee stock options outstanding were approximately 107,000, 3,000 and zero for the years ended December 31, 2017, 2016, and 2015, respectively. The Company has the following convertible senior notes outstanding: $172.5 million convertible senior notes due 2020 at a conversion price equivalent to approximately $45.72 per share of the Company’s common stock (the “2020 Convertible Notes”), $161.0 million convertible senior notes due 2021 at a conversion price equivalent to approximately $59.39 per share of the Company’s common stock (the “2021 Convertible Notes”) and $150.0 million convertible senior notes due 2022 at a conversion price equivalent to approximately $45.57 per share of the Company’s common stock (the “2022 Convertible Notes”). Prior to November 2017, the company had $115.0 million convertible senior notes due 2017 at a conversion price equivalent to approximately $31.56 per share of the Company’s common stock (the “2017 Convertible Notes”). In the event of conversion, the 2017 Convertible Notes were convertible into cash up to the aggregate principal amount and permit the excess conversion premium to be settled in cash or shares of the Company’s common stock. For the 2020 Convertible Notes,2021 Convertible Notes and 2022 Convertible Notes, the Company has the option to pay cash, issue shares of common stock or any combination thereof for the aggregate amount due upon conversion. The Company’s intent is to settle the principal amount of the 2020, 2021 and 2022 Convertible Notes in cash upon conversion. As a result, upon conversion of all the convertible senior notes, only the amounts payable in excess of the principal amounts are considered in diluted earnings per share under the treasury stock method. Diluted earnings per share during the periods presented above included the effect of the common shares issuable upon conversion of certain of the convertible senior notes because the average stock price exceeded the conversion price of these notes. However, as described in Note 9, “Debt-Encore Convertible Notes,” the Company entered into certain hedge transactions that have the effect of increasing the effective conversion price of the 2017 Convertible Notes to $60.00, the 2020 Convertible Notes to $61.55, and the 2021 Convertible Notes to $83.14. On January 2, 2014 the 2017 Convertible Notes became convertible as certain conditions for conversion were met in the immediately preceding calendar quarter as defined in the applicable indenture. In November 2017, the 2017 Convertible Notes were converted.
