| Background and Summary of Significant Accounting Policies | BACKGROUND AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (a) The Company Globus Medical, Inc., together with its subsidiaries, is a medical device company that develops and commercializes solutions for the treatment of musculoskeletal disorders. We are primarily focused on implants that promote healing in patients with spine disorders, but recently launched a robotic guidance and navigation system and products to treat patients who have experienced orthopedic traumas. We are an engineering-driven company with a history of rapidly developing and commercializing advanced products and procedures that assist surgeons in effectively treating their patients, respond to evolving surgeon needs and address new treatment options. Since our inception in 2003, we have launched over 180 products and offer a comprehensive portfolio of innovative and differentiated products addressing a broad array of spinal pathologies, anatomies and surgical approaches. We are headquartered in Audubon, Pennsylvania, and market and sell our products through our exclusive sales force in the United States, as well as within North, Central & South America, Europe, Asia, Africa and Australia. The sales force consists of direct sales representatives and distributor sales representatives employed by exclusive independent distributors. The terms the “Company,” “Globus,” “we,” “us” and “our” refer to Globus Medical, Inc. and, where applicable, our consolidated subsidiaries. (b) Basis of Presentation The accompanying interim unaudited condensed consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles (“U.S. GAAP”) for interim financial statements and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, certain information and footnote disclosures normally included in complete financial statements prepared in accordance with U.S. GAAP have been condensed or omitted pursuant to the rules and regulations of the Securities and Exchange Commission (“SEC”). As such, the information included in this Quarterly Report on Form 10-Q should be read in conjunction with the consolidated financial statements and accompanying footnotes included in our Annual Report on Form 10-K for the year ended December 31, 2017 . In the opinion of management, the statements include all adjustments necessary, which are of a normal and recurring nature, for the fair presentation of our financial position and of the results for the three- and six- month periods presented. The results of operations for any interim period are not indicative of results for the full year. During the fourth quarter of 2017, the Company identified and recorded an adjustment to its December 31, 2016 consolidated balance sheet to correct the presentation of $65.8 million of its Variable Rate Demand Notes (“VRDNs”) as short-term marketable securities instead of cash and cash equivalents. Accordingly, the statement of cash flows for the year ended December 31, 2016 has been adjusted to appropriately increase purchases of marketable securities by $63.3 million , resulting in an increase in net cash used in investing activities and a decrease to cash and cash equivalents, end of period of $63.3 million . The statement of cash flows for the year ended December 31, 2015 has been adjusted to appropriately increase purchases of marketable securities by $2.5 million , resulting in an increase in net cash used in investing activities and a decrease to cash and cash equivalents, end of period of $2.5 million . The statement of cash flows for the six months ended June 30, 2017 has been adjusted to appropriately increase purchases of marketable securities, maturities of marketable securities and sales of marketable securities by $19.1 million , $0.7 million and $23.2 million respectively, resulting in a decrease in net cash used in investing activities and an increase to cash and cash equivalents, end of period of $4.8 million . In accordance with FASB Topic ASC 320, Investments-Debt and Equity Securities , based on our ability to market and sell these instruments and our intent to not hold such instruments until maturity, we account for VRDNs as available-for-sale, and carry them at their fair value. VRDNs are similar to short-term debt instruments because their interest rates are reset periodically. Investments in these securities can be sold for cash on the auction date. We classified VRDNs at June 30, 2017 as short-term based on the reset dates. The Company did not own VRDNs as of December 31, 2017 and does not own VRDNs as of June 30, 2018 . (c) Principles of Consolidation The accompanying condensed consolidated financial statements include the accounts of Globus and its wholly-owned subsidiaries. All intercompany balances and transactions are eliminated in consolidation. (d) Use of Estimates The preparation of the condensed consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosures of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting period. We base our estimates, in part, on historical experience that management believes to be reasonable under the circumstances. Actual results could differ from those estimates. Estimates and assumptions are periodically reviewed and the effects of revisions are reflected in the condensed consolidated financial statements in the period they are determined to be necessary. Significant areas that require management’s estimates include intangible assets, business acquisition liabilities, allowance for doubtful accounts, stock-based compensation, write-down for excess and obsolete inventory, useful lives of assets, the outcome of litigation, recoverability of intangible assets and income taxes. We are subject to risks and uncertainties due to changes in the healthcare environment, regulatory oversight, competition, and legislation that may cause actual results to differ from estimated results. During fourth quarter of 2017, we completed a review of the estimated useful life of our Instruments and Modules and cases. Based on historical useful life information, forecasted product life cycles and demand expectations, the useful life of Instruments and Modules and cases was extended from three to five years. This was accounted for as a change in accounting estimate and was made on a prospective basis effective October 1, 2017. For the three months ended June 30, 2018 , depreciation expense was lower by approximately $1.5 million than it would have been had the useful life of these assets not been extended. The effect of this change on basic and diluted earnings per share for the three months ended June 30, 2018 was $0.01 per share. For the six months ended June 30, 2018 , depreciation expense was lower by approximately $3.1 million with a diluted earnings per share impact of $0.03 per share. (e) Cash, Cash Equivalents, and Restricted Cash The following table provides a reconciliation of cash, cash equivalents, and restricted cash reported within the statement of financial position that sum to the total of the same such amounts shown in the statement of cash flows: (In thousands) June 30, 2018 December 31, 2017 June 30, 2017 December 31, 2016 Cash and cash equivalents $ 119,944 $ 118,817 $ 88,744 $ 66,954 Restricted cash — — 478 477 Total cash, cash equivalents, and restricted cash as presented in the condensed consolidated statement of cash flows $ 119,944 $ 118,817 $ 89,222 $ 67,431 (f) Marketable Securities Our marketable securities include municipal bonds, corporate debt securities, commercial paper, securities of U.S. government-sponsored agencies and asset-backed securities, and are classified as available-for-sale as of June 30, 2018 . Available-for-sale securities are recorded at fair value in both short-term and long-term marketable securities on our condensed consolidated balance sheets. The change in fair value for available-for-sale securities is recorded, net of taxes, as a component of accumulated other comprehensive income or loss on our condensed consolidated balance sheets. Premiums and discounts are recognized over the life of the related security as an adjustment to yield using the straight-line method. Realized gains or losses from the sale of our marketable securities are determined on a specific identification basis. Realized gains and losses, along with interest income and the amortization/accretion of premiums/discounts are included as a component of other income, net, on our condensed consolidated statements of income. Interest receivable is recorded as a component of prepaid expenses and other current assets on our condensed consolidated balance sheets. We maintain a portfolio of various holdings, types and maturities, though most of the securities in our portfolio could be liquidated at minimal cost at any time. We invest in securities that meet or exceed standards as defined in our investment policy. Our policy also limits the amount of credit exposure to any one issue, issuer or type of security. We review our securities for other-than-temporary impairment at each reporting period. If an unrealized loss for any security is considered to be other-than-temporary, the loss will be recognized in our condensed consolidated statement of income in the period the determination is made. (g) Inventories Inventories are stated at the lower of cost or net realizable value. Cost is determined on a first-in, first-out basis. The majority of our inventories are finished goods and we utilize both in-house manufacturing and third-party suppliers to source our products. We periodically evaluate the carrying value of our inventories in relation to our estimated forecast of product demand, which takes into consideration the estimated life cycle of product releases. When quantities on hand exceed estimated sales forecasts, we record a write-down for such excess inventories. (h) Property and Equipment Purchases of property and equipment included in accounts payable and accrued expenses were $6.8 million and $5.7 million during the six months ended June 30, 2018 and June 30, 2017 , respectively. (i) Revenue Recognition Revenue is recognized upon transfer of control of promised products or services to customers in an amount that reflects the consideration we expect to receive in exchange for those products or services. Sales and other taxes we collect concurrent with revenue-producing activities are excluded from revenue. Incidental items that are immaterial in the context of the contract are recognized as expense. For purposes of disclosing disaggregated revenue, we disaggregate our revenue, into two categories, Spine and Emerging Technologies, based on the timing of revenue recognition. Our Spine products are comprised of our entire spinal implant portfolio, including traditional interbody fusion devices, our expandable cages, products designed for minimally invasive surgical techniques, motion preservation devices, regenerative biologics technologies and interventional pain management solutions. The majority of our Spine contracts have a single performance obligation and revenue is recognized at a point in time. Our Emerging Technology products consist of our imaging, navigational and robotic (“INR”) technologies and orthopedic trauma devices. The majority of our Emerging Technology product contracts typically contain multiple performance obligations, including maintenance and support, and revenue is recognized as we fulfill each performance obligation. For contracts with multiple performance obligations, we allocate the contract’s transaction price to each performance obligation using our best estimate of the standalone selling price of each distinct good or service in the contract. Our policy is to classify shipping and handling costs billed to customers as sales and the related expenses as cost of goods sold. Nature of Products and Services A significant portion of our Spine product revenue is generated from consigned inventory maintained at hospitals or with sales representatives. Revenue from the sale of consigned Spine products is recognized when we transfer control, which occurs at the time the product is used or implanted. For all other Spine product transactions, we recognize revenue when we transfer title to the goods, provided there are no remaining performance obligations that will affect the customer’s final acceptance of the sale. We use an observable price to determine the stand-alone selling price for the identified performance obligation. Revenue from the sale of Emerging Technology products is generally recognized when title transfers to the customer which occurs at the time the product is delivered. Depending on the terms of the arrangement, we may also defer the recognition of a portion of the consideration received as we have to satisfy a future performance obligation to provide maintenance and support. We use an observable price to determine the stand-alone selling price for each separate performance obligation. Contract Balances Timing of revenue recognition may differ from the timing of invoicing to customers. We record a receivable when revenue is recognized prior to invoicing, or deferred revenue when revenue is recognized subsequent to invoicing. Deferred revenue is comprised mainly of unearned revenue related to the sales of certain Emerging Technology products, which includes maintenance and support services. Deferred revenue is generally invoiced annually at the beginning of each contract period and recognized ratably over the coverage period. For the three and six months ended June 30, 2018 , there was an immaterial amount of revenue recognized from previously deferred revenue. Disaggregation of Revenue The following table represents total sales by revenue stream: Three Months Ended Six Months Ended (In thousands) June 30, June 30, June 30, June 30, Spine products $ 159,569 $ 152,390 $ 321,197 $ 308,199 Emerging Technology products 13,815 — 26,598 — Total sales $ 173,384 $ 152,390 $ 347,795 $ 308,199 (j) Other Income On June 21, 2018, we sold assets for $5.0 million , of which $3.0 million was collected upon closing of the sale and the remaining $2.0 million recorded under prepaid expenses and other current assets in the accompanying condensed consolidated balance sheet. (k) Recently Issued Accounting Pronouncements In February 2016, the FASB released ASU 2016-02, Leases (Topic 842) (“ASU 2016-02”). Under ASU 2016-02, a right-of-use asset and lease obligation will be recorded for all leases with terms greater than 12 months, whether operating or financing, while the income statement will reflect lease expense for operating leases and amortization/interest expense for financing leases. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, with early adoption permitted, and requires the use of the modified retrospective method, which will require adjustment to all comparative periods presented in the consolidated financial statements. We are currently evaluating the impact of this update on our financial position, results of operations, and disclosures. In January 2017, the FASB released ASU 2017-04, Intangibles - Goodwill and Other (Topic 805): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), which eliminates the Step 2 calculation for the implied fair value of goodwill to measure a goodwill impairment charge. Under the updated standard, an entity will record an impairment charge based on the excess of a reporting unit’s carrying amount over its fair value. ASU 2017-04 does not change the guidance on completing Step 1 of the goodwill impairment test and still allows an entity to perform the optional qualitative goodwill impairment assessment before determining whether to proceed to Step 1. This update is effective for annual and interim goodwill impairment tests in fiscal years beginning after December 15, 2019 with early adoption permitted for any impairment test performed on testing dates after January 1, 2017. We are currently evaluating the timing and impact of the new standard on our financial position, results of operations and disclosures. In February 2018, the FASB released ASU 2018-02, Income Statement - Reporting Comprehensive Income (Topic 220) , Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income (“ASU 2018-02”). Prior to ASU 2018-02, GAAP required the remeasurement of deferred tax assets and liabilities as a result of a change in tax laws or rates to be presented in net income from continuing operations, even in situations in which the related income tax effects of items in accumulated other comprehensive income were originally recognized in other comprehensive income. As a result, such items, referred to as stranded tax effects, did not reflect the appropriate tax rate. Under ASU 2018-02, entities are permitted, but not required, to reclassify from accumulated other comprehensive income to retained earnings those stranded tax effects resulting from the Tax Act. ASU 2018-02 is effective for all entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the timing and impact of the new standard on our financial position, results of operations and disclosures. In June 2018, the FASB released ASU 2018-07, Compensation—Stock Compensation (Topic 718) , (“ASU 2018-07”), which expanded the scope of Topic 718 to include share-based payment transactions for acquiring goods and services from nonemployees. ASU 2018-07 specifies that Topic 718 applies to all share-based payment transactions in which a grantor acquires goods or services to be used or consumed in a grantor’s own operations by issuing share-based payment awards. This update is effective for public entities for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Early adoption is permitted. We are currently evaluating the timing and impact of the new standard on our financial position, results of operations and disclosures. (l) Recently Adopted Accounting Pronouncements In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”) . ASU 2014-09 amends the guidance in former Topic 605, Revenue Recognition , and most other existing revenue guidance in US GAAP. Under the new standard, an entity will recognize revenue to depict the transfer of goods or services to customers in amounts that reflect the payment to which the entity expects to be entitled in exchange for those goods or services and provide additional disclosures. As amended, the effective date for public entities is annual reporting periods beginning after December 15, 2017 and interim periods therein. We adopted the standard on January 1, 2018, using the modified retrospective method. We implemented internal controls and key system functionality to enable the preparation of financial information upon adoption. The adoption of this standard did not have a material impact on our financial position, results of operations, and disclosures. In October 2016, the FASB released ASU 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other Than Inventory (“ASU 2016-16”). ASU 2016-16 removes the current exception in US GAAP prohibiting entities from recognizing current and deferred income tax expenses or benefits related to transfer of assets, other than inventory, within the consolidated entity. The current exception to defer the recognition of any tax impact on the transfer of inventory within the consolidated entity until it is sold to a third party remains unaffected. This update is effective for public entities for annual reporting periods beginning after December 15, 2017. We adopted ASU 2016-16 on January 1, 2018. This standard does not have a material impact on our financial position, results of operations, and disclosures. In November 2016, the FASB released ASU 2016-18, Statement of Cash Flows (Topic 230): Restricted Cash (“ASU 2016-18”), which requires that amounts generally described as restricted cash and restricted cash equivalents be included with cash and cash equivalents when reconciling the total beginning and ending amounts for the periods shown on the statement of cash flows. Transfers between cash and cash equivalents and restricted cash and restricted cash equivalents will no longer be presented in the statement of cash flows. The amendments in this update should be applied using a retrospective transition method to each period presented. This update is effective for annual periods beginning after December 15, 2017, and interim periods within those fiscal years; early adoption is permitted, including adoption in an interim period. We adopted ASU 2016-18 on January 1, 2018. This standard does not have a material impact on our financial position, results of operations, and disclosures. In January 2017, the FASB released ASU 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business (“ASU 2017-01”), which clarifies the definition of a business with the objective of adding guidance to assist entities with evaluating whether transactions should be accounted for as acquisitions or disposals of assets or businesses. The amendments in this ASU should be applied prospectively and are effective for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years, with early application permitted. No disclosures are required at transition. We adopted ASU 2017-01 on January 1, 2018. This standard does not have a material impact on our financial position, results of operations, and disclosures. In May 2017, the FASB released ASU 2017-09, Compensation - Stock Compensation (Topic 718): Scope of Modification Accounting (“ASU 2017-09”), which clarifies the changes to terms or conditions of a share based payment award that requires application of modification accounting under Topic 718. A change to an award should be accounted for as a modification unless the fair value of the modified award is the same as the original award, the vesting conditions do not change, and the classification as an equity or liability instrument does not change. This update is effective for annual reporting periods, and interim periods within those annual periods, beginning after December 15, 2017. Early application is permitted and prospective application is required for awards modified on or after the adoption date. We adopted ASU 2017-09 on January 1, 2018. This standard does not have a material impact on our financial position, results of operations, and disclosures. |
