3. Stock-Based Compensation ExpenseExpense. The stock-based compensation expense before income tax expense for the three and six months ended June 30,March 31, 2019 and 2018, and 2017, consisted of the following (in thousands):

 $1,691


We recognize stock-based compensation expense (net of a forfeiture rate) for those awards which are expected to vest on a straight-line basis over the requisite service period. We estimate the forfeiture rate based on our historical experience and expectations about future forfeitures. As of June 30, 2018,March 31, 2019, the total remaining unrecognized compensation cost related to non-vested stock options, net of expected forfeitures, was approximately $22.4$32.8 million and iswas expected to be recognized over a weighted average period of 3.463.48 years.


During the three and six-month periodsthree-month period ended June 30,March 31, 2019, we granted stock-based awards representing 909,603 shares of our common stock. During the three-month period ended March 31, 2018, we granted stock-based awards representing 200,000 and 692,002 shares of our common stock, respectively. During the three and six-month periods ended June 30, 2017, we granted stock-based awards representing approximately 1.28 million492,002 shares of our common stock. We use the Black-Scholes methodology to value the stock-based compensation expense for options. In applying the Black-Scholes methodology to the option grants, the fair value of our stock-based awards granted was estimated using the following assumptions for the periods indicated below:



 Three Months Ended March 31,
 2019 2018
Risk-free interest rate2.42% - 2.56% 2.63%
Expected option term3.0 - 5.0 years 5.0 years
Expected dividend yield 
Expected price volatility28.93% - 33.69% 34.32%

 Six Months Ended June 30,
 2018 2017
Risk-free interest rate2.63% - 2.77% 1.77% - 1.79%
Expected option life5.0 years 5.0 years
Expected dividend yield 
Expected price volatility34.06% - 34.32% 33.81% - 34.03%


The average risk-free interest rate is determined using the U.S. Treasury rate in effect as of the date of grant, based on the expected term of the stock options. We determine the expected term of the stock options using the historical exercise behavior of employees. The expected price volatility was determined using a weighted average of daily historical volatility of our stock price over the corresponding expected option lifeterm and implied volatility based on recent trends of the daily historical volatility. For options with a vesting period, compensation expense is recognized on a straight-line basis over the service period, which corresponds to the vesting period.

5. Acquisitions. On March 28, 2019, we paid $2 million to acquire convertible participating preferred shares of Fluidx Medical Technology, LLC ("Fluidx"), owner of certain technology proposed to be used in the development of embolic and adhesive agents for use in arterial, venous, vascular graft and cardiovascular applications inside and outside the heart and related appendages. Our investment in Fluidx has been recorded as an equity investment accounted for at cost and reflected within other assets in the accompanying consolidated balance sheets because we are not able to exercise significant influence over the operations of Fluidx. Our total current investment in Fluidx represents an ownership of approximately 12.7% of the outstanding equity interests of Fluidx.

On December 14, 2018, we consummated an acquisition transaction contemplated by an asset purchase agreement with Vascular Insights, LLC and VI Management, Inc. (combined "Vascular Insights") and acquired Vascular Insight's intellectual property rights, inventory and certain other assets, including, the ClariVein® IC system and the ClariVein OC system. The ClariVein systems are specialty infusion and occlusion catheter systems with rotating wire tips designed for the controlled 360-degree dispersion of physician-specified agents to the targeted treatment area. We accounted for this acquisition as a business combination. The purchase consideration included an upfront payment of $40 million, and we are obligated to pay up to an additional $20 million based on achieving certain revenue milestones specified in the asset purchase agreement. The sales and results of operations related to this acquisition have been included in our cardiovascular segment. During the three-month period ended March 31, 2019, net sales of products acquired from Vascular Insights were approximately $1.5 million. It is not practical to separately report earnings related to the products acquired from Vascular Insights, as we cannot split out sales costs related solely to the products we acquired from Vascular Insights, principally because our sales representatives sell multiple products (including the products we acquired from Vascular Insights) in our cardiovascular business segment. Acquisition-related costs associated with the Vascular Insights acquisition, which were included in selling, general and administrative expenses during the year ended December 31, 2018, were not material. We are in the process of finalizing the net working capital adjustment pursuant to the asset purchase agreement. The purchase price was preliminarily allocated as follows (in thousands):
 Inventories$1,353
 Intangibles 
 Developed technology32,750
 Customer list840
 Trademarks1,410
 Goodwill21,847
   
 Total net assets acquired$58,200


We are amortizing the developed technology intangible asset acquired from Vascular Insights over 12 years, the related trademarks over nine years and the customer list on an accelerated basis over eight years. The total weighted-average amortization period for these acquired intangible assets is approximately 11.8 years.

On November 13, 2018, we consummated an acquisition transaction contemplated by a merger agreement to acquire Cianna Medical, Inc. ("Cianna Medical"). The purchase consideration consisted of an upfront payment of $135 million plus a final working capital adjustment of approximately $1.2 million in cash, with potential earn-out payments of up to an additional $15 million for achievement of supply chain and scalability metrics and up to an additional $50 million for the achievement of sales milestones. Cianna Medical developed the first non-radioactive, wire-free breast cancer localization system. Its SCOUT® and SAVI® Brachy technologies are FDA-cleared and address unmet needs in the delivery of radiation therapy, tumor localization and surgical guidance. We accounted for this acquisition as a business combination. During the three-month period ended March 31, 2019, net sales of Cianna Medical products were approximately $12.8 million. It is not practical to separately report earnings related to the products acquired from Cianna Medical, as we cannot split out sales costs related solely to the products we acquired from Cianna Medical, principally because our sales representatives sell multiple products (including the products we acquired from Cianna Medical) in our cardiovascular business segment. Acquisition-related costs associated with the Cianna Medical acquisition, which were included in selling, general and administrative expenses during the year ended December 31, 2018, were approximately $3.5 million. The following table summarizes the preliminary purchase price allocated to the net assets acquired from Cianna Medical (in thousands):

5. Acquisitions.On May 23, 2018, we entered into an asset purchase agreement with DirectACCESS Medical, LLC (“DirectACCESS”) to acquire its assets, including, certain product distribution agreements for the FirstChoice™ Ultra High Pressure PTA Balloon Catheter. We accounted for this acquisition as a business combination. The purchase price for the assets was approximately $7.3 million. The sales and results of operations related to the acquisition have been included in our cardiovascular segment since the acquisition date and were not material. Acquisition-related costs associated with the DirectACCESS acquisition, which were included in selling, general and administrative expenses in our consolidated statements of income,during the year ended December 31, 2018, were not material.

On May 18, 2018, we paid $750,000 for a distribution agreement with QXMédical, LLC ("QXMédical") for the Q50® PLUS Stent Graft Balloon Catheter. We accounted for this acquisition as an asset purchase. We are amortizing the distribution agreement intangible asset over a period of ten years.
On April 6, 2018, we entered into long-term agreements with NinePoint Medical, Inc. (“NinePoint”), pursuant to which, we (a) became the exclusive worldwide distributor for the NvisionVLE® Imaging System with Real-time Targeting™ using Optical Coherence Tomography (OCT) and (b) acquired an option to purchase up to 100% of the outstanding equity in NinePoint throughout a three-month period commencing 18 months subsequent to the agreement date, both in exchange for total consideration of $10.0 million. We accounted for this transaction as an asset purchase. The results of operations related to the distribution agreement have been included in our endoscopy segment since the acquisition date. During the period from April 6, 2018 to June 30, 2018, our net sales of NinePoint products were approximately $1.1 million. We believe the NinePoint products will enhance the product offerings of our Endotek operating segment and will be another step in our strategy to add therapy and disease-state products to our portfolio. The NinePoint products have 510(k) clearance in the United States, and NinePoint is preparing a CE mark application. We plan to launch the NinePoint products globally on a measured basis.

In addition, we made a loan to NinePoint for $10.5 million with a maturity date of April 6, 2023, at which time the loan, together with accrued interest thereon, will be due and payable. The loan bears interest at a rate of 9% and is collateralized by NinePoint's rights, interest and title to the NvisionVLE® Imaging System and any other product owned or licensed by NinePoint. This loan has been recorded as a note receivable within other long-term assets in our consolidated balance sheets.

On February 14, 2018, we acquired certain divested assets from Becton, Dickinson and Company ("BD"), for an aggregate purchase price of $100.3 million.

During the three and six months ended June 30, 2018, our net sales of ITL products were approximately $2.0 million and $4.2 million, respectively. It is not practical to separately report the earnings related to the ITL acquisition, as we cannot split out sales costs related solely to the products we acquired from ITL, principally because our sales representatives sell multiple products (including the products we acquired from ITL) in our cardiovascular business segment.

The assets and liabilities in the purchase price allocation for the Argon critical care acquisition are stated at fair value based on estimates of fair value using available information and making assumptions our management believes are reasonable. The following table summarizes the purchase price allocated to the net tangible and intangible assets acquired and liabilities assumed (in thousands):

(1) 
The total fair value of the net assets acquired from Argon exceeded the purchase price, resulting in a gain on bargain purchase which was recorded within other income (expense) in our consolidated statements of income. We believe the reason for the gain on bargain purchase was a result of the divestiture of a non-strategic, slow-growth critical care business for Argon. It is our understanding that the divestiture allows Argon to focus on its higher growth interventional portfolio. A reduction of $1.2 million was recorded since the bargain purchase gain was first presented in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2017, resulting from our ongoing activities, including reassessment of the assets acquired and liabilities assumed. The purchase price allocation for this acquisition is now final.

With respect to the Argon critical care assets, we are amortizing developed technology over seven years and customer lists on an accelerated basis over five years. While U.S. trademarks can be renewed indefinitely, we estimate that we will generate cash flow from the acquired trademarks for a period of five years from the acquisition date. The total weighted-average amortization period for these acquired intangible assets is 6.0 years.

On January 31, 2017, we acquired substantially all the assets, including intellectual property covered by approximately 40 patents and pending applications, and assumed certain liabilities, of Catheter Connections, Inc. (“Catheter Connections”), in exchange for payment of $38.0 million. Catheter Connections, based in Salt Lake City, Utah, developed and marketed the DualCap® System, an innovative family of disinfecting products designed to protect patients from intravenous infections resulting from infusion therapy. We accounted for this acquisition as a business combination.

Acquisition-related costs associated with the Catheter Connections acquisition during the year ended December 31, 2017, which were included in selling, general and administrative expenses were approximately $482,000. The results of operations related to this acquisition have been included in our cardiovascular segment since the acquisition date. During the three and six months ended June 30, 2018, our net sales of the products acquired from Catheter Connections were approximately $3.1 million and $6.3 million, respectively. It is not practical to separately report the earnings related to the products acquired from Catheter Connections, as we cannot split out sales costs related solely to those products, principally because our sales representatives sell multiple products (including the DualCap System) in the cardiovascular business segment. The purchase price was allocated as follows (in thousands):

Assets Acquired 
Trade receivables$958
Inventories2,157
Prepaid expenses and other assets85
Property and equipment1,472

Total assets acquired38,361
  
Liabilities Assumed 
Trade payables(338)
Accrued expenses(23)
Total liabilities assumed(361)
  
Net assets acquired$38,000

We are amortizing the Catheter Connections developed technology asset over 12 years, the related trademarks over 10 years, and the associated customer list on an accelerated basis over eight years. We have estimated the weighted average life of the intangible Catheter Connections assets acquired to be approximately 11.7 years.

On July 6, 2016, we acquired all of the issued and outstanding shares of DFINE Inc. ("DFINE"). The DFINE acquisition added a line of vertebral augmentation products for the treatment of vertebral compression fractures, as well as medical devices used to treat metastatic spine tumors. We made an initial payment of $97.5 million to certain DFINE stockholders on July 6, 2016 and paid approximately $578,000 related to a net working capital adjustment subject to review by Merit and the preferred stockholders of DFINE. We accounted for the acquisition as a business combination. Acquisition-related costs during the year ended December 31, 2016, which are included in selling, general, and administrative expenses were approximately $1.6 million. The results of operations related to this acquisition have been included in our cardiovascular segment since the acquisition date. During the three and six months ended June 30, 2018, our net sales of DFINE products were approximately $7.2 million and $14.5 million, respectively. It is not practical to separately report the earnings related to the DFINE acquisition, as we cannot split out sales costs related to DFINE products, principally because our sales representatives are selling multiple products (including DFINE products) in the cardiovascular business segment. The purchase price was allocated to the net tangible and intangible assets acquired and liabilities assumed, based on estimated fair values, as follows (in thousands):

Net assets acquired, net of cash received of $1,327$95,635

The gross amount of trade receivables we acquired in the acquisition was approximately $4.3 million, of which approximately $224,000 was expected to be uncollectible or returned. With respect to the DFINE assets, we are amortizing developed technology over 15 years and customer lists on an accelerated basis over nine years. While U.S. trademarks can be renewed indefinitely, we currently estimate that we will generate cash flow from the acquired trademarks for a period of 15 years from the acquisition date. The total weighted-average amortization period for these acquired intangible assets is 14.8 years.
On February 4, 2016, we purchased the HeRO® Graft device and other related assets from CryoLife, Inc., a developer of medical devices based in Kennesaw, Georgia ("CryoLife"). The HeRO Graft is a fully subcutaneous vascular access system intended for use in maintaining long-term vascular access for chronic hemodialysis patients who have failing fistulas, grafts or are catheter dependent due to a central venous blockage. The purchase price was $18.5 million, which was paid in full during 2016. We accounted for this acquisition as a business combination. The purchase price was allocated as follows (in thousands):
Assets Acquired 
Inventories$2,455
Property and equipment290
Intangibles 
Developed technology12,100
Trademarks700
Customers Lists400
Goodwill2,555
  
Total assets acquired$18,500

We are amortizing the developed HeRO Graft technology asset over 10 years, the related trademarks over 5.5 years, and the associated customer lists over 12 years. We have estimated the weighted average life of the intangible HeRO Graft assets acquired to be approximately 9.8 years. Acquisition-related costs related to the HeRO Graft device and other related assets during the year ended December 31, 2016, which are included in selling, general and administrative expenses, were not material. The results of operations related to this acquisition have been included in our cardiovascular segment since the acquisition date. During the three and six months ended June 30, 2018, our net sales of the products acquired from CryoLife were approximately $2.2 million and $4.2 million, respectively. It is not practical to separately report the earnings related to the products acquired from CryoLife, as

we cannot split out sales costs related to those products, principally because our sales representatives are selling multiple products (including the HeRO Graft device) in the cardiovascular business segment.

The unaudited pro forma information set forth above is for informational purposes only and includes adjustments related to the step-up of acquired inventories, amortization expense of acquired intangible assets and interest expense on long-term debt and changes in the timing of the recognition of the gain on bargain purchase.debt. The pro forma information should not be considered indicative of actual results that would have been achieved if the acquisition of the Argon critical care divisionCianna Medical and Vascular Insights had occurred on January 1, 2016,2017, or results that may be obtained in any future period. The pro forma consolidated results of operations do not include the acquisition of assets from BD because it was deemed impracticable to obtain information to determine net income associated with the acquired product lines which represent a small product line of a large, consolidated company without standalone financial information. The pro forma consolidated results of operations do not include the DirectACCESS ITL, Laurane, Osseon, VAT or Catheter Connections acquisitionsacquisition as we do not deem the pro forma effect of these transactionsthis transaction to be material.
    
The goodwill arising from the acquisitions discussed above consists largely of the synergies and economies of scale we hope to achieve from combining the acquired assets and operations with our historical operations. The goodwill recognized from certain acquisitions is expected to be deductible for income tax purposes.



6. Revenue from Contracts with Customers.


In accordance with Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with Customers (Topic 606) ("ASC 606"), we recognize revenue when a customer obtains control of promised goods. The amount of revenue recognized reflects the consideration we expect to receive in exchange for these goods. To achieve this core principle, we apply the following five steps:

1.
Identify the contract with the customer. A contract with a customer exists when (i) we enter into an enforceable contract with a customer that defines each party’s rights regarding the goods to be transferred and identifies the payment terms related to these goods, (ii) the contract has commercial substance and, (iii) we determine that collection of substantially all consideration for services that are transferred is probable based on the customer’s intent and ability to pay the promised consideration. We do not have significant costs to obtain contracts with customers. For commissions on product sales, we have elected the practical expedient to expense the costs as incurred if the amortization period would have been one year or less.

2.
Identify the performance obligations in the contract. Generally, our contracts with customers do not include multiple performance obligations to be completed over a period of time. Our performance obligations relate to delivering single-use medical products to a customer, subject to the shipping terms of the contract. Limited warranties are provided, under which we typically accept returns and provide either replacement parts or refunds. We do not have significant returns. We do not typically offer extended warranty or service plans.

3.
Determine the transaction price. Payment by the customer is due under customary fixed payment terms, and we evaluate if collectability is reasonably assured. None of our contracts as of June 30, 2018 contained a significant financing

component. Further, our methodology to estimate and recognize variable consideration is consistent with the requirements of ASC 606. Revenue is recorded at the net sales price, which includes estimates of variable consideration such as product returns, rebates, discounts, and other adjustments. The estimates of variable consideration are based on historical payment experience, historical and projected sales data, and current contract terms. Variable consideration is included in revenue only to the extent that it is probable that a significant reversal of the revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenues.

4.
Allocate the transaction price to performance obligations in the contract. We typically do not have multiple performance obligations in our contracts with customers. As such, we recognize revenue upon delivery of the product to the customer's control at contractually stated pricing.

5.
Recognize revenue when or as we satisfy a performance obligation. We satisfy performance obligations at a point in time upon either shipment or delivery of goods, in accordance with the terms of each contract with the customer. We do not have significant service revenue.


Disaggregation of Revenue


The disaggregation of revenue is based on type of product and geographical region. For descriptions of our product offerings and segments, see Note 1213 in our 20172018 Form 10-K.

7. Segment Reporting. We report our operations in two operating segments: cardiovascular and endoscopy. Our cardiovascular segment consists of cardiology and radiology medical device products which assist in diagnosing and treating coronary artery disease, peripheral vascular disease and other non-vascular diseases and includes embolotherapeutic, cardiac rhythm management ("CRM"), electrophysiology ("EP"), critical care, and interventional oncology and spine devices.devices, and our Cianna Medical product line. Our endoscopy segment focuses on the gastroenterology, pulmonary and thoracic surgery specialties, with a portfolio consisting primarily of stents, dilation balloons, certain inflation devices, guidewires,guide wires, and other disposable products.products, as well as the products related to our distribution agreement with NinePoint Medical Inc. ("NinePoint Medical"). We evaluate the performance of our operating segments based on net sales and operating income.

8. Recently Issued Financial Accounting StandardsStandards.


Recently Adopted


In OctoberFebruary 2016, the Financial Accounting Standards Board (the "FASB"("FASB") issued ASUAccounting Standards Update ("ASU") No. 2016-16, Income Taxes2016-02, Leases (Topic 740): Intra-Entity Transfers of Assets Other than Inventory842) ("ASC 842"), which requires lessees to recognize right-of-use ("ROU") assets and related lease liabilities on the recognitionbalance sheet for all leases greater than one year in duration. We adopted ASC 842 on January 1, 2019 using a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the income tax consequences of an intra-entity transfer of an asset, other than inventory, whenearliest comparative period presented in the transfer occurs. ASU 2016-16 became effectivefinancial statements. The modified retrospective approach did not require any transition accounting for us as of January 1, 2018.leases that expired before the earliest comparative period presented. The adoption of ASU 2016-16this standard resulted in the recording of ROU assets and lease liabilities for all of our lease agreements with original terms of greater than one year. The adoption of ASC 842 did not have a materialsignificant impact on our consolidated financial statements.


In August 2016, the FASB issued ASU No. 2016-15, Statement of Cash Flows (Topic 230): Classification of Certain Cash Receipts and Cash Payments, which addresses eight specific cash flow issues with the objective of reducing the existing diversity in practice in how certain cash receipts and cash payments are presented and classified in the statement of cash flows. We adopted ASU 2016-15 on January 1, 2018. The adoption of ASU 2016-15 did not have a material impact on our consolidated financial statements.

In January 2016, the FASB issued ASU No. 2016-01, Financial Instruments - Overall: Recognition and Measurement of Financial Assets and Financial Liabilities, which amends the guidance regarding the classification and measurement of financial instruments. Changes to the current guidance primarily affect the accounting for equity investments, financial liabilities under the fair value option, and the presentation and disclosure requirements for financial instruments. In addition, ASU 2016-01 clarifies guidance related to the valuation allowance assessment when recognizing deferred tax assets resulting from unrealized losses on available-for-sale debt securities. We adopted ASU 2016-01 on January 1, 2018. The adoption of ASU 2016-01 did not have a material impact on our consolidated financial statements.

The FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), which provides a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. We adopted this ASU (and all subsequent ASUs that modified Topic 606) effective January 1, 2018 on a modified retrospective basis. Adoption of this standard did not result in significant changes to our accounting policies, business processes, systems or controls, or have a material impact on our financial position, resultsstatements of operations or cash flows. As such, prior period amounts are not adjusted and continueSee Note 14 for the required disclosures relating to be reported under accounting standards then in effect, and we did not record a cumulative adjustment to the opening equity balance of retained earnings as of January 1, 2018. However, additional disclosures have been added in accordance with the requirements of Topic 606 and are reflected in Note 6.our lease agreements.


Not Yet Adopted

In June 2018, the FASB issued ASU 2018-07, Compensation-Stock Compensation (Topic 718): Improvements to Nonemployee Share-Based Payment Accounting, which simplifies the accounting for nonemployee share-based payment transactions by expanding the scope of ASC Topic 718, Compensation - Stock Compensation, to include share-based payment transactions for acquiring goods and services from nonemployees. Under the new standard, most of the guidance on stock compensation payments to nonemployees would be aligned with the requirements for share-based payments granted to employees. This standard isbecame effective for annual reporting periods beginning after December 15, 2018, and interim periods within those fiscal years, with early adoption permitted. While we continue to assess the potential impact of this standard, we do not expect theus on January 1, 2019. The adoption of this standard todid not have a material impact on our consolidated financial statements.


In February 2018, the FASB issued ASU 2018-02, Income Statement-Reporting Comprehensive Income (Topic 220): Reclassification of Certain Tax Effects from Accumulated Other Comprehensive Income, which allows a reclassification from accumulated other comprehensive income to retained earnings for stranded tax effects resulting from U.S. federal tax legislation commonly referred to as the Tax Cuts and Jobs Act, which was enacted in December 2017 (the "2017 Tax Act"). ASU 2018-02 isbecame effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Earlyus on January 1, 2019. The adoption is permitted. We are currently evaluating the anticipatedof this standard did not have a material impact of adopting ASU 2018-02 on our consolidated financial statements.


In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815): Targeted Improvements to Accounting for Hedging Activities, which expands and refines hedge accounting for both financial and non-financial risk components, aligns the recognition and presentation of the effects of hedging instruments and hedge items in the financial statements, and includes certain targeted improvements to ease the application of current guidance related to the assessment of hedge effectiveness. ASU 2017-12 isbecame effective for fiscal years beginning after December 15, 2018, and interim periods within those fiscal years. Earlyus on January 1, 2019. The adoption is permitted. We are currently evaluating the anticipatedof this standard did not have a material impact of adopting ASU 2017-12 on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases (Topic 842), which eliminates the current tests for lease classification under U.S. GAAP and requires lessees to recognize the right-of-use assets and related lease liabilities on the balance sheet for all leases greater than one year in duration. ASU 2016-02 is effective for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years. Early adoption of ASU 2016-02 is permitted. ASU 2016-02 provides that lessees (for capital and operating leases) and lessors (for sales-type, direct financing, and operating leases) must apply a modified retrospective transition approach for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements. The modified retrospective approach would not require any transition accounting for leases that expired before the earliest comparative period presented. Lessees and lessors may not apply a full retrospective transition approach. We are assessing the impact that ASU 2016-02 is anticipated to have on our consolidated financial statements. We currently expect that most of our operating lease commitments will be subject to the new standard and recognized as lease liabilities and right-of-use assets upon our adoption of ASU 2016-02.


We do not believe any other issued and not yet effective accounting standards will be relevant to our consolidated financial statements.




9. Income Taxes. On December 22, 2017, the 2017 Tax Act was signed into law. At December 31, 2017, we recorded a provisional net tax benefit related to the remeasurement of deferred taxes and a one-time tax expense for the transition tax. In accordance with SEC Staff Accounting Bulletin 118 (“SAB 118”), income tax effects of the 2017 Tax Act may be refined upon obtaining, preparing, and/or analyzing additional information during the measurement period and such changes could be material. During the measurement period, provisional amounts may also be adjusted for the effects, if any, of interpretative guidance issued after December 31, 2017 by U.S. regulatory and standard-setting bodies. As of June 30, 2018, the amounts recorded for the 2017 Tax Act remain provisional and may be impacted by further analysis and subsequently issued guidance.

For tax years beginning after December 31, 2017, the 2017 Tax Act introduces new provisions of U.S. taxation of certain Global Intangible Low-Taxed Income (“GILTI”). We have not yet determined our policy election with respect to whether to record deferred taxes for temporary basis differences expected to reverse as GILTI in future periods, or account for taxes on GILTI using the period cost method. We have, however, included an estimate of the current GILTI impact in our tax provision for the three and six months ended June 30, 2018.

Our non-U.S. earnings are currently considered as indefinitely reinvested overseas. Previously, any repatriation by way of a dividend may have been subject to both U.S. federal and state income taxes, as adjusted for any non-U.S. tax credits. Under the 2017 Tax Act, such dividends should no longer be subject to U.S. federal tax. We are still analyzing how the 2017 Tax Act impacts our existing accounting position to indefinitely reinvest foreign earnings and have yet to determine whether we plan to change our position. We will record the tax effects of any change to our existing assertion in the period that we complete our analysis. If such earnings were to be distributed, any foreign withholding taxes could be material.

Our provision for income taxes for the three months ended June 30,March 31, 2019 and 2018 and 2017 was a tax expense of approximately $624,000$651,000 and $1.8$1.1 million, respectively, which resulted in an effective tax rate of 5.4%9.5% and 16.2%, respectively. Our provision for income taxes for the six months ended June 30, 2018 and 2017 was a tax expense of approximately $1.7 million and $2.5 million, respectively, which resulted in an effective tax rate of 9.6% and 9.4%17.1%, respectively. The decrease in the income tax expense and effective income tax rate for the secondfirst quarter of 2019 as compared to the first quarter of 2018 compared to the second quarter of 2017 was primarily caused by a decreasedue to an increase in the federal statutory tax rate, as well as a discrete tax benefit related to share-based payment awards. Despite the decrease resulting from these items, the effective tax rate for the six months ended June 30, 2018 is relatively unchanged when compared to the corresponding period in 2017 due primarily to the nontaxable gain on the bargain purchase recorded in connection with the 2017 acquisition of the Argon critical care division.

2016 Term Loan and Revolving Credit Loans


On July 6, 2016, we entered into a Second Amended and Restated Credit Agreement (as amended to date, the “Second Amended Credit Agreement”), with Wells Fargo Bank, National Association, as administrative agent, swingline lender and a lender, and Wells Fargo Securities, LLC, as sole lead arranger and sole bookrunner. In addition to Wells Fargo Bank, National Association, Bank of America, N.A., U.S. Bank, National Association, and HSBC Bank USA, National Association, are parties to the Second Amended Credit Agreement as lenders. The Second Amended Credit Agreement amends and restates in its entirety our previously outstanding Amended and Restated Credit Agreement and all amendments thereto. The Second Amended Credit Agreement was amended on September 28, 2016 to allow for a new revolving credit loan to our wholly-owned subsidiary, on March 20, 2017 to allow flexibility in how we apply net proceeds received from equity issuances to prepay outstanding indebtedness, on December 13, 2017 to increase the revolving credit commitment by $100 million up to $375 million, and on March 28, 2018 to amend certain debt covenants.


The Second Amended Credit Agreement provides for a term loan of $150 million and a revolving credit commitment up to an aggregate amount of $375 million, which includes a reserve of $25 million to make swingline loans from time to time. The term loan is payable in quarterly installments in the amounts provided in the Second Amended Credit Agreement until the maturity date of July 6, 2021, at which time the term and revolving credit loans, together with accrued interest thereon, will be due and payable. At any time prior to the maturity date, we may repay any amounts owing under all revolving credit loans, term loans, and all swingline loans in whole or in part, subject to certain minimum thresholds, without premium or penalty, other than breakage costs.


Revolving credit loans denominated in dollars and term loans made under the Second Amended Credit Agreement bear interest, at our election, at either a Base Rate or Eurocurrency Base Rate (as such terms are defined in the Second Amended Credit Agreement) plus the applicable margin, which increases as our Consolidated Total Leverage Ratio (as defined in the Second Amended Credit Agreement) increases. Revolving credit loans denominated in an Alternative Currency (as defined in the Second Amended Credit Agreement) bear interest at the Eurocurrency rate plus the applicable margin. Swingline loans bear interest at the Base Rate plus the applicable margin. Upon an event of default, the interest rate may be increased by 2.0%. The revolving credit commitment also carries a commitment fee of 0.15% to 0.40% per annum on the unused portion.


The Second Amended Credit Agreement is collateralized by substantially all our assets. The Second Amended Credit Agreement contains covenants, representations and warranties, and other terms customary for loans of this nature. The Second Amended Credit Agreement requires that we maintain certain financial covenants, as follows:

   Covenant Requirement
Consolidated Total Leverage Ratio (1)
  
 January 1, 2018 and thereafter 3.5 to 1.0
Consolidated EBITDA (2)
 1.25 to 1.0
Consolidated Net Income (3)
 $0
Facility Capital Expenditures (4)
 $30 million
    
(1) 
Maximum Consolidated Total Leverage Ratio (as defined in the Second Amended Credit Agreement) as of any fiscal quarter end.
(2) 
Minimum ratio of Consolidated EBITDA (as defined in the Second Amended Credit Agreement and adjusted for certain expenditures) to Consolidated Fixed Charges (as defined in the Second Amended Credit Agreement) for any period of four consecutive fiscal quarters.
(3) 
Minimum level of Consolidated Net Income (as defined in the Second Amended Credit Agreement) for certain periods, and subject to certain adjustments.
(4) 
Maximum level of the aggregate amount of all Facility Capital Expenditures (as defined in the Second Amended Credit Agreement) in any fiscal year.



Additionally, the Second Amended Credit Agreement contains customary events of default and affirmative and negative covenants for transactions of this type. As of June 30, 2018,March 31, 2019, we believe we were in compliance with all covenants set forth in the Second Amended Credit Agreement.


As of June 30, 2018,March 31, 2019, we had outstanding borrowings of approximately $407$377.5 million under the Second Amended Credit Agreement, with additional available borrowings of approximately $47.8$65.5 million, based on the leverage ratio required pursuant to the Second Amended Credit Agreement. Our interest rate as of June 30, 2018March 31, 2019 was a fixed rate of 2.87%2.62% on $175 million as a result an interest rate swap

(see (see Note 11) and a variable floating rate of 3.84%4.00% on $232$202.5 million. Our interest rate as of December 31, 20172018 was a fixed rate of 2.68%2.12% on $175 million as a result of an interest rate swap and a variable floating rate of 2.82%3.52% on $97$213.5 million.


Collateralized Debt Facility


On March 14, 2018,January 11, 2019, we renewed our loan agreement with HSBC Bank USA, National Association ("HSBC Bank") whereby HSBC Bank agreed to provide us with a loan in the amount of approximately $7.0 million. The loan maturesmatured and was settled on JulyApril 10, 2018, with an extension available at our option, subject to certain conditions.2019. The loan agreement bearsbore interest at the three-month London Inter-Bank Offered Rate (“LIBOR”) plus 1.0%, which resetsreset quarterly. The loan iswas secured by assets having a value not less than the currently outstanding loan balance. The loan containscontained covenants, representations and warranties and other terms customary for loans of this nature. As of June 30, 2018,March 31, 2019, our interest rate on the loan was a variable rate of 3.26%3.43%.

11. DerivativesDerivatives.
 
General. Our earnings and cash flows are subject to fluctuations due to changes in interest rates and foreign currency exchange rates, and we seek to mitigate a portion of these risks by entering into derivative contracts. The derivatives we use are interest rate swaps and foreign currency forward contracts. We recognize derivatives as either assets or liabilities at fair value in the accompanying consolidated balance sheets, regardless of whether or not hedge accounting is applied. We report cash flows arising from our hedging instruments consistent with the classification of cash flows from the underlying hedged items. Accordingly, cash flows associated with our derivative programsinstruments are classified as operating activities in the accompanying consolidated statements of cash flows.

We formally document, designate and assess the effectiveness of transactions that receive hedge accounting initially and on an ongoing basis. Changes in the fair value of derivatives that qualify for hedge accounting treatment are recorded, net of applicable taxes, in accumulated other comprehensive income (loss), a component of stockholders’ equity in the accompanying consolidated balance sheets. ForWhen the ineffective portions of qualifying hedges, the change in fair value is recorded throughhedged transaction occurs, gains or losses are reclassified into earnings in the same line item associated with the forecasted transaction and in the same period of change.or periods during which the hedged transaction affects earnings. Changes in the fair value of derivatives not designated as hedging instruments are recorded in earnings throughout the term of the derivative.


Interest Rate Risk. A portion of our debt bears interest at variable interest rates and, therefore, we are subject to variability in the cash paid for interest expense. In order to mitigate a portion of this risk, we use a hedging strategy to reduce the variability of cash flows in the interest payments associated with a portion of the variable-rate debt outstanding under our Second Amended Credit Agreement that is solely due to changes in the benchmark interest rate.


DerivativesDerivative Instruments Designated as Cash Flow Hedges


On August 5, 2016, we entered into a pay-fixed, receive-variable interest rate swap with a current notional amount of $175.0$175 million with Wells Fargo to fix the one-month LIBOR rate at 1.12%. The variable portion of the interest rate swap is tied to the one-month LIBOR rate (the benchmark interest rate). On a monthly basis, the interest rates under both the interest rate swap and the underlying debt reset, the swap is settled with the counterparty, and interest is paid. The interest rate swap is scheduled to expire on July 6, 2021.


At June 30, 2018March 31, 2019 and December 31, 2017,2018, our interest rate swap qualified as a cash flow hedge. The fair value of our interest rate swap at June 30, 2018March 31, 2019 was an asset of approximately $8.0$4.3 million, which was partially offset by approximately $2.1$1.1 million in

deferred taxes. The fair value of our interest rate swap at December 31, 20172018 was an asset of approximately $5.7$5.8 million, which was offset by approximately $1.5 million in deferred taxes.


Foreign Currency RiskRisk. We operate on a global basis and are exposed to the risk that our financial condition, results of operations, and cash flows could be adversely affected by changes in foreign currency exchange rates. To reduce the potential effects of foreign currency exchange rate movements on net earnings, we enter into derivative financial instruments in the form of foreign currency exchange forward contracts with major financial institutions. Our policy is to enter into foreign currency derivative contracts with maturities of up to two years. We are primarily exposed to foreign currency exchange rate risk with respect to transactions and balances denominated in Euros, British Pounds, Chinese Renminbi, Mexican Pesos, Brazilian Reals, Australian Dollars, Hong Kong Dollars, Swiss Francs, Swedish Krona, Canadian Dollars, Danish Krone, Japanese Yen, KoreaKorean Won, and Singapore Dollars. We do not use derivative financial instruments for trading or speculative purposes. We are not subject to any credit risk contingent features related to our derivative contracts, and counterparty risk is managed by allocating derivative contracts among several major financial institutions.


DerivativesDerivative Instruments Designated as Cash Flow Hedges


For derivative instruments that are designated and qualify as cash flow hedges, the effective portion of the gain or loss on the derivative instrument is reported as a component of other comprehensive income (loss) and reclassified into earnings in the same line item associated with the forecasted transaction and in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any (i.e., the ineffective portion) or hedge components excluded from the assessment of effectiveness, are recognized in earnings during the current period. We enter into forward contracts on various foreign currencies to manage the risk associated with forecasted exchange rates which impact revenues, cost of sales, and operating expenses in various international markets. The objective of the hedges is to reduce the variability of cash flows associated with the forecasted purchase or sale of the associated foreign currencies.

We enter into approximately 100150 cash flow foreign currency hedges every month. As of June 30, 2018,March 31, 2019, we had entered into foreign currency forward contracts, which qualified as cash flow hedges, with the following notional amounts (in thousands and in local currencies):

DerivativesDerivative Instruments Not Designated as Cash Flow Hedges


We forecast our net exposure in various receivables and payables to fluctuations in the value of various currencies, and we enter into foreign currency forward contracts to mitigate that exposure. We enter into approximately 20 foreign currency fair value hedges every month. As of June 30, 2018,March 31, 2019, we had entered into foreign currency forward contracts related to those balance sheet accounts, with the following notional amounts (in thousands and in local currencies):

Certain of our business combinations involve the potential for the payment of future contingent consideration, generally based on a percentage of future product sales or upon attaining specified future revenue milestones. See Note 5 for further information regarding these acquisitions. The contingent consideration liability is re-measured at the estimated fair value at the end of each reporting period with the change in fair value recognized within operating expenses in the accompanying consolidated statements of income.income for such period. We measure the initial liability and re-measure the liability on a recurring basis using Level 3 inputs as defined under authoritative guidance for fair value measurements.

As of June 30, 2018,March 31, 2019, approximately $10.6$59.2 million in contingent consideration liability was included in other long-term obligations and approximately $301,000$23.3 million was included in accrued expenses in our consolidated balance sheet. As of December 31, 2017,2018, approximately $10.7$58.5 million in contingent consideration liability was included in other long-term obligations and $289,000$23.8 million was included in accrued expenses in our consolidated balance sheet. The cashCash paid to settle the contingent consideration liability recognized at fair value as of the acquisition date (including measurement-period adjustments) has been reflected as a cash outflow from financing activities in the accompanying consolidated statements of cash flows.


During the year ended December 31, 2016, we sold a cost method investment for cash and for the right to receive additional payments based on various contingent milestones. We determined the fair value of the contingent payments using Level 3 inputs

defined under authoritative guidance for fair value measurements, and we recorded a contingent receivable asset, which as of June 30, 2018March 31, 2019 and December 31, 20172018 had a value of approximately $474,000$627,000 and $760,000, respectively.$607,000, respectively, recorded as a current asset in other receivables in our consolidated balance sheets. We record any changes in fair value to operating expenses as part of our cardiovascular segment in our consolidated statements of income. During the three and six months ended June 30, 2018,March 31, 2019, we recorded a lossgain on the contingent receivable of approximately $79,000 and $132,000, respectively$20,000. During the three months ended March 31, 2018, we recorded a loss of approximately $53,000 and received payments of approximately $0 and $153,000 respectively. As of June 30, 2018, approximately $184,000 was included in other long-term assets and approximately $290,000 was included in other receivables as a current asset in our consolidated balance sheet. As of December 31, 2017, approximately $319,000 was included in other long-term assets and approximately $441,000 was included in other receivables as a current asset in our consolidated balance sheet.related to the contingent receivable.

The contingent consideration liability and contingent receivable are re-measured to fair value each reporting period using projected revenues, discount rates, probabilities of payment, and projected payment dates. Projected contingent payment amounts are discounted back to the current period using a discounted cash flow model. Projected revenues are based on our most recent internal operational budgets and long-range strategic plans. An increase (decrease) in either the discount rate or the time to payment, in isolation, may result in a significantly lower (higher) fair value measurement. A decrease in the probability of any milestone payment may result in lower fair value measurements. Our determination of the fair value of the contingent consideration liability and contingent receivable could change in future periods based upon our ongoing evaluation of these significant unobservable inputs. We intend to record any such change in fair value to operating expenses in our consolidated statements of income.

During the three and six-month periodsthree-month period ended June 30, 2018,March 31, 2019, we had losses of approximately $29,000 and $86,000, respectively,$211,000, compared to losses of approximately $1,000 and $19,000$57,000 for the three and six-month periodsthree-month period ended June 30, 2017, respectively,March 31, 2018, related to the measurement of non-financial assets at fair value on a nonrecurring basis subsequent to their initial recognition.


We believe the carrying amount of cash and cash equivalents, receivables, and trade payables approximate fair value because of the immediate, short-term maturity of these financial instruments. Our long-term debt re-prices frequently due to variable rates and entails no significant changes in credit risk and, as a result, we believe the fair value of long-term debt approximates carrying value. The fair value of assets and liabilities whose carrying value approximates fair value is determined using Level 2 inputs, with the exception of cash and cash equivalents, which are Level 1 inputs.

14. Leases. We adopted ASC 842 using the modified retrospective approach, electing the practical expedient that allows us not to restate our comparative periods prior to the adoption of the standard on January 1, 2019. As such, the disclosures required under ASC 842 are not presented for periods before the date of adoption. For the comparative periods prior to adoption, we present the disclosures which were required under ASC 840.

We have operating leases for facilities used for manufacturing, R&D, sales and distribution, and office space, as well as leases for manufacturing and office equipment, vehicles, and land (in Singapore and South Jordan, Utah). Our leases have remaining terms of approximately one year to 19 years. A number of our lease agreements contain options to renew at our discretion for periods of up to 30 years and options to terminate the leases within one year. The lease term used to calculate right-of-use ("ROU") assets and lease liabilities includes renewal and termination options that are deemed reasonably certain to be exercised. Lease agreements with lease and non-lease components are generally accounted for as a single lease component. We do not have any bargain purchase options in our leases. For leases with an initial term of one year or less, we do not record a ROU asset or lease liability on our consolidated balance sheet. Substantially all of the ROU assets and lease liabilities as of March 31, 2019 recorded on our consolidated balance sheet are related to our cardiovascular segment.

We sublease a portion of one of our facilities to a third party. We also lease certain hardware consoles to customers through our distribution agreement with NinePoint Medical and record rental revenue as a component of net sales. Rental revenue under such console leasing arrangements for the three months ended March 31, 2019 and 2018 was insignificant.

The following was included in our consolidated balance sheet as of March 31, 2019 (in thousands):

During the year ended December 31, 2015, we entered into sale and leaseback transactions to finance certain production equipment for approximately $2.0 million. At that time, we deferred the gain from the sale and leaseback transaction, of which approximately $93,000 remained as of December 31, 2018. As part of the adoption of ASC 842, we wrote-off the deferred gain as an adjustment to equity through retained earnings during the three months ended March 31, 2019.

We recognize lease expense on a straight-line basis over the term of the lease. The components of lease costs for the three months ended March 31, 2019 are as follows, in thousands:

Cash paid for amounts included in the measurement of lease liabilities $3,713
Right-of-use assets obtained in exchange for lease obligations $1,162


Generally, our lease agreements do not specify an implicit rate. Therefore, we estimate our incremental borrowing rate, which is defined as the interest rate we would pay to borrow on a collateralized basis, considering such factors as length of lease term and the risks of the economic environment in which the leased asset operates. As of March 31, 2019, the following disclosures for remaining lease term and incremental borrowing rates were applicable:

As of March 31, 2019, we had additional operating leases for office space that had not yet commenced. These leases will commence during 2019 and are not significant.



14.15. Commitments and Contingencies. In the ordinary course of business, we are involved in various claims and litigation matters. These claims and litigation matters may include actions involving product liability, intellectual property, contract disputes, and employment or other matters that are significant to our business. Based upon our review of currently available information, we do not believe any such actions are likely to be, individually or in the aggregate, materially adverse to our business, financial condition, results of operations or liquidity.


In addition to the foregoing matters, in October 2016, we received a subpoena from the U.S. Department of Justice seeking information on certain of our marketing and promotional practices. We are in the process of responding to the subpoena, which we anticipate will continue during 2018.2019. We have incurred, and anticipate that we will continue to incur, substantial costs in connection with the matter. The investigation is ongoing and at this stage we are unable to predict its scope, duration or outcome. Investigations such as this may result in the imposition of, among other things, significant damages, injunctions, fines or civil or criminal claims or penalties against our company or individuals. Legal expenses we incurred in responding to the U.S. Department of Justice subpoena for the three and six-monththree-month periods ended June 30,March 31, 2019 and 2018 were approximately $1.6$1.7 million and $3.3$1.7 million, respectively.


In the event of unexpected further developments, it is possible that the ultimate resolution of any of the foregoing matters, or other similar matters, if resolved in a manner unfavorable to us, may be materially adverse to our business, financial condition, results of operations or liquidity. Legal costs for these matters, such as outside counsel fees and expenses, are charged to expense in the period incurred.




15. Issuance of Common Stock. On March 28, 2017, we closed a public offering of 5,175,000 shares of common stock and received proceeds of approximately $136.6 million, which is net of approximately $8.8 million in underwriting discounts and commissions and approximately $816,000 in other direct cost incurred and paid by us in connection with this equity offering. The net proceeds from the offering were used primarily to repay outstanding indebtedness under our Second Amended Credit Agreement (including our term loan and revolving credit loans).


16. Subsequent Events. On July 30, 2018, we closed a public offering of 4,025,000 shares of common stock and received proceeds of approximately $205.4 million, which is net of approximately $10.4 million in underwriting discounts and commissions, and we paid approximately $500,000 in other direct costs incurred in connection with this equity offering. The net proceeds from the offering were used primarily to repay revolving credit loans under our Second Amended Credit Agreement.

Recent Developments and Trends


In addition to the trends identified in the 20172018 Form 10-K under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Overview,” we believe that our business in 20182019 will be impacted by the following recent events and trends:


In February 2018, we acquired certain divested assets from BD for an aggregate purchase priceAlthough uncertainty over the future of $100.3 million. The acquired assets include the soft tissue core needle biopsy products sold under the tradenames of Achieve® Programmable Automatic Biopsy System, Temno® Biopsy System, Tru-Cut® Biopsy Needles as well as Aspira® Pleural Effusion Drainage Kits, and the Aspira® Peritoneal Drainage System. During the three and six-month periods ended June 30, 2018, our net sales of BD products were approximately $12.2 million and $18.5 million, respectively.

On April 6, 2018, we entered into long-term agreements with NinePoint Medical, Inc. (“NinePoint”), pursuant to which, we (a) became the exclusive worldwide distributor for the NvisionVLE® Imaging System with Real-time Targeting™ using Optical Coherence Tomography (OCT) and (b) acquired an option to purchase up to 100% of the outstanding equity in NinePoint both in exchange for total consideration of $10.0 million. In addition, we made a loan to NinePoint for $10.5 million. We believe the NinePoint products will enhance the product offerings of our Endotek division (in our endoscopy segment) and will be another step to adding therapy and disease-state products to our portfolio. The NinePoint products have 510(k) clearanceBrexit negotiations in the United States, and NinePoint is preparing a CE mark application. During the period from April 6, 2018 to June 30, 2018, our net sales of NinePoint products were approximately $1.1 million.

In May 2018,Kingdom continues, we entered into an agreement for the acquisition of product distribution agreements for the DirectACCESS FirstChoice™ Ultra High Pressure PTA Balloon Catheter and executed a distribution agreement for the QXMédical Q50® PLUS Stent Graft Balloon Catheter.


A competitor recently experienced substantial global supply shortagescurrently believe that due to internal issues, which has resultedour newly operational distribution and training center in increased demandReading, United Kingdom and other plans we have in place, we are prepared to avoid material disruption to our business.

Several new products are scheduled for our Merit Laureate® Hydrophilic Guide Wires, our offering of microcatheters (including the Merit Maestro®, SwiftNINJA® and the recently introduced Pursue™ Microcatheter), our Impress® Diagnostic Catheters and our vascular sheaths (including the recently introduced Prelude IDeal™ and PreludeEASE™ product offerings).

Additionally, we expect that (a) our net sales forintroduction in the remainder of 2018 will be positively impacted by recently-awarded tenders, anticipated releases of2019, including the TEMNO Elite™ biopsy device, next generation Heartspan® transseptal needle, PreludeSYNC DISTAL hemostasis device and HeRO® arterial graft component, among others. We currently believe these new products will contribute to future sales growth and commencement of productionmargin improvement.

Our transition of the Laurane product linemanufacturing activities associated with the products we acquired from BD in February 2018 to our Irish facility and (b) our net income forin Tijuana, Mexico is currently on schedule to be completed by the remainderend of 2018 will be positively impacted by continued manufacturing efficiencies, cost-saving measures, and sales of our biopsy and drainage products, partially offset by several demand-based factors, including changes in our product mix, increases in revenue in certain markets served by distributors, and increases in labor costs and logistical expenses of addressing global supply requirements.2019.


Our acquisition of Cianna Medical is complete, and our integration of the Cianna Medical operations continues according to our expectations. We currently expect regulatory approval of the SAVI SCOUT® product for sale in Europe in the coming months.

The term loan is payable in quarterly installments in the amounts provided in the Second Amended Credit Agreement until the maturity date of July 6, 2021, at which time the term and revolving credit loans, together with accrued interest thereon, will be due and payable. At any time prior to the maturity date, we may repay any amounts owing under all revolving credit loans, term loans, and all swingline loans in whole or in part, subject to certain minimum thresholds, without premium or penalty, other than breakage costs.


Revolving credit loans denominated in dollars and term loans made under the Second Amended Credit Agreement bear interest, at our election, at either a Base Rate or Eurocurrency Base Rate (as such terms are defined in the Second Amended Credit Agreement) plus the applicable margin, which increases as our Consolidated Total Leverage Ratio (as defined in the Second Amended Credit Agreement) increases. Revolving credit loans denominated in an Alternative Currency (as defined in the Second Amended Credit Agreement) bear interest at the Eurocurrency rate plus the applicable margin. Swingline loans bear interest at the Base Rate plus the applicable margin. Upon an event of default, the interest rate may be increased by 2.0%. The revolving credit commitment will also carry a commitment fee of 0.15% to 0.40% per annum on the unused portion.


The Second Amended Credit Agreement is collateralized by substantially all our assets. The Second Amended Credit Agreement contains covenants, representations and warranties and other terms customary for loans of this nature. The Second Amended Credit Agreement requires that we maintain certain financial covenants, as follows:

   Covenant Requirement
Consolidated Total Leverage Ratio (1)
  
 January 1, 2018 and thereafter 3.5 to 1.0
Consolidated EBITDA (2)
 1.25 to 1.0
Consolidated Net Income (3)
 $0
Facility Capital Expenditures (4)
 $30 million
    
(1) 
Maximum Consolidated Total Leverage Ratio (as defined in the Second Amended Credit Agreement) as of any fiscal quarter end.
(2) 
Minimum ratio of Consolidated EBITDA (as defined in the Second Amended Credit Agreement and adjusted for certain expenditures) to Consolidated Fixed Charges (as defined in the Second Amended Credit Agreement) for any period of four consecutive fiscal quarters.
(3) 
Minimum level of Consolidated Net Income (as defined in the Second Amended Credit Agreement) for certain periods, and subject to certain adjustments.
(4) 
Maximum level of the aggregate amount of all Facility Capital Expenditures (as defined in the Second Amended Credit Agreement) in any fiscal year.


Additionally, the Second Amended Credit Agreement contains customary events of default and affirmative and negative covenants for transactions of this type. As of June 30, 2018,March 31, 2019, we believe we were in compliance with all covenants set forth in the Second Amended Credit Agreement.


As of June 30, 2018,March 31, 2019, we had outstanding borrowings of approximately $407.0$377.5 million under the Second Amended Credit Agreement (an increase(a decrease in long-term debt of approximately $132.6$11.0 million from December 31, 2017, which was principally due to our acquisition of assets from BD, NinePoint and DirectACCESS)2018 as we paid down the balance), with additional available borrowings of approximately $47.8$65.5 million, based on the leverage ratio required pursuant to the Second Amended Credit Agreement. Our interest rate as of June 30, 2018March 31, 2019 was a fixed rate of 2.87%2.62% on $175.0$175 million as a result of an interest rate swap (see Note 11 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report) and a variable floating rate of 3.84%4.00% on $232.0$202.5 million. Our interest rate as of December 31, 20172018 was a fixed rate of 2.68%2.12% on $175.0$175 million as a result of an interest rate swap and a variable floating rate of 2.82%3.52% on $97.0$213.5 million.


As discussed in Note 16 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report, the net proceeds from our offering of common stock, which closed on July 30, 2018, were used primarily to repay outstanding borrowings (primarily revolving credit loans) under the Second Amended Credit Agreement.

Cash flows used in investing activities.Our cash flows used in investing activities for the six-monththree-month period ended June 30, 2018March 31, 2019 was approximately $162.5$21.0 million compared to approximately $73.7$117.3 million for the six-monththree-month period ended June 30, 2017, an increaseMarch 31, 2018, a decrease of approximately $88.8$96.3 million. This increasedecrease was primarily a result of an increasea decrease of approximately $63.8$98.3 million in net cash paid for acquisitions during the sixthree months ended June 30, 2018,March 31, 2019, compared to the sixthree months ended June 30, 2017March 31, 2018 (see Note 5 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report), combined withpartially offset by a $13.8$2.0 million increase in capital expenditures for property and equipment. Capital expenditures for property and equipment were approximately $31.6$18.3 million and $17.8$16.2 million for the six-monththree-month periods ended June 30,March 31, 2019 and 2018, and 2017, respectively.


We currently believe that our existing cash balances, anticipated future cash flows from operations and borrowings under the Second Amended Credit Agreement will be adequate to fund our current and currently planned future operations for the next twelve months and the foreseeable future. In the event we pursue and complete significant transactions or acquisitions in the future, additional funds will likely be required to meet our strategic needs, which may require us to raise additional funds in the debt or equity markets.


Off-Balance Sheet Arrangements


Under SEC regulations, we are required to disclose our off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, such as changes in financial condition, revenues or expenses,

results of operations, liquidity, capital expenditures or capital resources that are material to investors. As of June 30, 2018,March 31, 2019, we have no off-balance sheet arrangements.


Critical Accounting Policies and Estimates


The SEC has requested that all registrants address their most critical accounting policies. The SEC has indicated that a “critical accounting policy” is one which is both important to the representation of the registrant’s financial condition and results and requires management’s most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain. We base our estimates on past experience and on various other assumptions our

management believes to be reasonable under the circumstances, the results of which form the basis for making judgments about carrying values of assets and liabilities that are not readily apparent from other sources. Actual results will differ, and may differ materially from these estimates under different assumptions or conditions. Additionally, changes in accounting estimates could occur in the future from period to period. Our management has discussed the development and selection of our most critical financial estimates with the audit committee of our Board of Directors. The following paragraphs identify our most critical accounting policies:
    
Inventory Obsolescence. Our management reviews on a quarterly basis inventory quantities on hand for unmarketable and/or slow-moving products that may expire prior to being sold. This review includes quantities on hand for both raw materials and finished goods. Based on this review, we provide adjustments for any slow-moving finished good products or raw materials that we believe will expire prior to being sold or used to produce a finished good and any products that are unmarketable. This review of inventory quantities for unmarketable and/or slow movingslow-moving products is based on forecasted product demand prior to expiration lives.
    
Forecasted unit demand is derived from our historical experience of product sales and production raw material usage. If market conditions become less favorable than those projected by our management, additional inventory write-downs may be required. During the years ended December 31, 2018, 2017 2016 and 2015,2016, we recorded obsolescence expense of approximately $8.2 million, $6.1 million $3.9 million and $2.8$3.9 million, respectively, and wrote off approximately $7.9 million, $2.9 million $2.8 million and $2.5$2.8 million, respectively. Based on this historical trend, we believe that our inventory balances as of June 30, 2018March 31, 2019 have been accurately adjusted for any unmarketable and/or slow movingslow-moving products that may expire prior to being sold.
    
Allowance for Doubtful Accounts. A majority of our receivables are with hospitals which, over our history, have demonstrated favorable collection rates. Therefore, we have experienced relatively minimal bad debts from hospital customers. In limited circumstances, we have written off bad debts as the result of the termination of our business relationships with foreign distributors. The most significant write-offs over our history have come from U.S. and international distributors.distributors, as well as from U.S. custom procedure tray manufacturers who bundle our products in surgical trays.
    
We maintain allowances for doubtful accounts relating to estimated losses resulting from the inability of our customers to make required payments. These allowances are based upon historical experience and a review of individual customer balances. If the financial condition of our customers were to deteriorate, resulting in an impairment of their ability to make payments, additional allowances may be required.
    
Stock-Based Compensation. We measure stock-based compensation cost at the grant date based on the value of the award and recognize the cost as an expense over the term of the vesting period. Judgment is required in estimating the fair value of share-basedstock-based awards granted and their expected forfeiture rate. If actual results differ significantly from these estimates, stock-based compensation expense and our results of operations could be materially impacted.
    
Income Taxes. Under our accounting policies, we initially recognize a tax position in our financial statements when it becomes more likely than not that the position will be sustained upon examination by the tax authorities. Such tax positions are initially and subsequently measured as the largest aggregate amount of tax positions that hashave a greater than 50% likelihood of being realized upon ultimate settlement with the tax authorities assuming full knowledge of the position and all relevant facts. Although we believe that our provisions for unrecognized tax positions are reasonable, we can make no assurance that the final tax outcome of these matters will not be different from that which we have reflected in our income tax provisions and accruals. The tax law is subject to varied interpretations, and we have taken positions related to certain matters where the law is subject to interpretation. Additionally, changes in tax law - such as the 2017 Tax Act - may be subject to evolving interpretation over a period of time following their enactment. Such differences and evolving interpretations could have a material impact on our income tax provisions and operating results in the period(s) in which we make such determination.
    
Goodwill and Intangible Asset Impairment and Contingent Consideration. We allocate any excess purchase price over the fair value of the net tangible and identifiable intangible assets acquired in a business combination to goodwill. We test our goodwill balances for impairment as of July 1 of each year, or whenever impairment indicators arise. We utilize several reporting units in

evaluating goodwill for impairment. We assess the estimated fair value of reporting units using a combination of a guideline public company market-based approach and a discounted cash flow income-based approach. If the carrying amount of a reporting unit exceeds the fair value of the reporting unit, an impairment charge is recognized in an amount equal to the excess of the carrying amount of the reporting unit goodwill over the implied fair value of that goodwill. This analysis requires significant judgment, including estimation of future cash flows and the length of time they will occur, which is based on internal forecasts, and a determination of a discount rate based on our weighted average cost of capital. During our annual test of goodwill balances in 2017,2018, which was completed during the third quarter of 2017,2018, we determined that the fair value of each reporting unit with goodwill exceeded the carrying amount by a significant amount.
    
We evaluate the recoverability of intangible assets subject to amortization whenever events or changes in circumstances indicate that an asset's carrying amount may not be recoverable. This analysis requires similar significant judgments as those discussed

above regarding goodwill, except that undiscounted cash flows are compared to the carrying amount of intangible assets to determine if impairment exists. In-process technology intangible assets, which are not subject to amortization until projects reach commercialization, are assessed for impairment at least annually and more frequently if events occur that would indicate a potential reduction in the fair value of the assets below their carrying value.

During the fourth quarter of 2017,year ended December 31, 2018, we compared the carrying value of the amortizing intangible assets acquired in our July 2015 acquisition of certain assets from Distal Access,Quellent, LLC ("Quellent"), all of which pertained to our cardiovascular segment, to the undiscounted cash flows expected to result from the asset group and determined that the carrying amount was not recoverable. We then determined the fair value of the amortizing assets related to the Distal AccessQuellent acquisition based on estimated future cash flows discounted back to their present value using a discount rate that reflects the risk profiles of the underlying activities. Some of the factors that influenced our estimated cash flows were slower than anticipated sales growth in the products acquired from our Distal AccessQuellent acquisition and uncertainty about future sales growth. The excess of the carrying value compared to the fair value was recognized as an intangible asset impairment charge. We recorded an impairment charge for Distal AccessQuellent of approximately $809,000 during the fourth quarter of 2017.$657,000.


Contingent consideration is an obligation by the buyer to transfer additional assets or equity interests to the former owner upon reaching certain performance targets. Certain of our business combinations involve the potential for the payment of future contingent consideration, generally based on a percentage of future product sales or upon attaining specified future revenue or other milestones. In connection with a business combination, any contingent consideration is recorded on the acquisition date based upon the consideration expected to be transferred in the future. We utilize a discounted cash flow method, which includes a probability factor for milestone payments, in valuing the contingent consideration liability. We re-measure the estimated liability each quarter and record changes in the estimated fair value through operating expense in our consolidated statements of income. Significant increases or decreases in our estimates could result in changes to the estimated fair value of our contingent consideration liability, as the result of changes in the timing and amount of revenue estimates, as well as changes in the discount rate or periods.



Item 3.QUANTITATIVE AND QUALITATIVE DICSLOSURES ABOUT MARKET RISK


Currency Risk


Our principal market risk relates to changes in the value of the following currencies relative to the U.S. Dollar (USD):
Euro (EUR)
Chinese Yuan Renminbi (CNY), and
British Pound (GBP).


We also have a limited market risk relating to the following currencies (among others):
Hong Kong Dollar (HKD),
Mexican Peso (MXN),
Australian Dollar (AUD),
Canadian Dollar (CAD),
Brazilian Real (BRL),
Swiss Franc (CHF),
Swedish Krona (SEK),
Danish Krone (DKK),
Singapore Dollars (SGD),
South Korean Won (KRW), and
Japanese Yen (JPY).


Our consolidated financial statements are denominated in, and our principal currency is, the U.S. Dollar. For the six-monththree-month period ended June 30, 2018,March 31, 2019, a portion of our net sales (approximately $143.4$75.9 million, representing approximately 33.5%31.9% of our aggregate net sales), was attributable to sales that were denominated in foreign currencies. All other international sales were denominated in U.S. Dollars.


Our Euro-denominated revenue represents our largest single currency risk. However, our Euro-denominated expenses associated with our European operations (manufacturing sites, a distribution facility and sales representatives) provide a natural hedge. Accordingly, changes in the Euro, and in particular a strengthening of the U.S. Dollar against the Euro, generally have a positive effect on our operating income. As we continue to expand our operations in China, we have been increasingly exposed to currency risk related to our CNY-denominated revenue. In general, a strengthening of the U.S. Dollar against CNY has a negative effect on our operating income. The following table presents the USD impact to reported operating income related to a hypothetical positive and negative 10% exchange rate fluctuation in the value of the U.S. Dollar relative to both the EUR and CNY (annual amounts):

During the three and six months ended June 30, 2018,March 31, 2019, exchange rate fluctuations of foreign currencies against the U.S. Dollar had the following impact on sales, cost of sales and gross profit (in thousands, except basis points):

(1) Represents approximately 68 basis points decrease in gross margin percentage for the three months ended March 31, 2019.


The impact to sales for the three and six months ended June 30, 2018March 31, 2019 was primarily a result of favorableunfavorable impacts due to sales denominated in EUR, CNY, AUD and GBP. The impact to cost of sales was primarily a result of unfavorablefavorable impacts from EUR fluctuations related to manufacturing costs from our facilities in Europe denominated in EUR and MXN fluctuations on our manufacturing costs from our facility in Tijuana, Mexico denominated in MXN.


We forecast our net exposure related to sales and expenses denominated in foreign currencies. As of June 30, 2018,March 31, 2019, we had entered into foreign currency forward contracts, which qualified as cash flow hedges, with the following notional amounts (in thousands and in local currencies):

We also forecast our net exposure in various receivables and payables to fluctuations in the value of various currencies, and we enter into foreign currency forward contracts to mitigate that exposure. As of June 30, 2018,March 31, 2019, we had entered into the following foreign currency forward contracts (which were not designated as hedging instruments) related to those balance sheet accounts (amounts in thousands and in local currencies):

See Note 11 to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report for a discussion of our foreign currency forward contracts.


Interest Rate Risk. As discussed in Note 10 to our condensed consolidated financial statements, as of June 30, 2018,March 31, 2019, we had outstanding borrowings of approximately $407.0$377.5 million under the Second Amended Credit Agreement, an increasea decrease in long-term debt of approximately $132.6$11.0 million from December 31, 2017, which was principally due to our acquisition of assets from BD, NinePoint and DirectACCESS. Accordingly, our2018 as we paid down balances. Our earnings and after-tax cash flow are increasingly affected by changes in interest rates. On August 5, 2016, we entered into a pay-fixed, receive-variable interest rate swap with Wells Fargo, which as of June 30, 2018March 31, 2019 had a notional amount of $175 million, to fix the one-month LIBOR rate at 1.12%. The interest rate swap is scheduled to expire on July 6, 2021. This instrument is intended to reduce our exposure to interest rate fluctuations and was not entered into for speculative purposes. Excluding the amount that is subject to a fixed rate under the interest rate swap and assuming the current level of borrowings remained the same, it is estimated that our interest expense and income before income taxes would change by approximately $2.3$2.0 million annually for each one percentage point change in the average interest rate under these borrowings.


In the event of an adverse change in interest rates, our management would likely take actions to mitigate our exposure. However, due to the uncertainty of the actions that would be taken and their possible effects, additional analysis is not possible at this time. Further, such analysis would not consider the effects of the change in the level of overall economic activity that could exist in such an environment.



Item 4.CONTROLS AND PROCEDURES
 
Evaluation of Disclosure Controls and Procedures
 
Our management is responsible for establishing and maintaining adequate disclosure controls and procedures for our company. Consequently, our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 under the Exchange Act as of June 30, 2018.March 31, 2019. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Based on that evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures are designed at a reasonable assurance level and are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.


Changes in Internal Control Over Financial Reporting
 
During the quarter ended June 30, 2018,March 31, 2019, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934).

PART II - OTHER INFORMATION




ITEM 1. LEGAL PROCEEDINGS
See Note 1415 “Commitments and Contingencies” set forth in the notes to our condensed consolidated financial statements included in Part I, Item 1 of this Quarterly Report.


ITEM 1A. RISK FACTORS
In addition to other information set forth in this Report, readers should carefully consider the factors discussed in Part I, Item 1A. "Risk Factors" of the 20172018 Form 10-K, as well as the amended and updated risk factors included below (which replace equivalent risk factors disclosed in Part I, Item 1A. "Risk Factors" of the 20172018 Form 10-K). Such risk factors could materially affect our business, financial condition or future results.


The risks described in our 20172018 Form 10-K and in the amended and updated risk factors below are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition and/or operating results.

We may be unable to successfully manage growth, particularly if accomplished through acquisitions, and the integration of acquired businesses may present significant challenges that could harm our operations.

Successful implementation of our business strategy will require that we effectively manage any associated growth. To manage growth effectively, our management will need to continue to implement changes in certain aspects of our business, to improve our information systems, infrastructure and operations to respond to increased demand, to attract and retain qualified personnel, and to develop, train, and manage an increasing number of management-level and other employees. Growth could place an increasing strain on our management, sales and other personnel, and on our financial, product design, marketing, distribution and other resources, and we could experience operating difficulties. Any failure to manage growth effectively could have a material adverse effect on our business, operations or financial condition.

Over the past several years, we have completed a series of significant acquisitions. As we grow through acquisitions and, at any given time, we may be considering a number of potential further acquisitions and strategic transactions, certain of which may also be significant. As we grow through acquisitions, we face the additional challenges of integrating the operations, culture, information management systems and other characteristics of the acquired entity with our own. Efforts to integrate future acquisitions may be hampered by delays, the loss of certain employees, suppliers or customers, proceedings resulting from employment terminations, culture clashes, unbudgeted costs, and other issues, which may occur at levels that are more severe or prolonged than anticipated. Additionally, past and future acquisitions may increase the risks of competition we face by, among other things, extending our operations into industry segments and product lines where we have few existing customers or qualified sales personnel and limited expertise. For example, although we acquired certain tunneled home drainage catheter and soft tissue core needle biopsy products from BD in February 2018, BD retained other products that directly compete with the products we acquired. As BD is a larger company with a more well-established market presence in such product lines, we may be unable to realize expected benefits from the acquisition in the timeframe anticipated or at all.

We have incurred, and will likely continue to incur, significant expenses in connection with negotiating and consummating various acquisition and other strategic transactions, and we may inherit significant liabilities in connection with prospective acquisitions or other strategic transactions, including regulatory, infringement, product liability, discrimination or other legal claims or issues. In addition, we may not realize competitive advantages, synergies or other benefits anticipated in connection with any such acquisition or other transaction. If we do not adequately identify targets for, or manage issues related to, our future acquisitions and similar transactions, such transactions may have an adverse effect on our business, operations or financial condition.

Use of our products in unapproved circumstances could expose us to liabilities.
The marketing clearances and approvals from the FDA and other regulators of certain of our products are, or are expected to be, limited to specific uses. We are prohibited from marketing or promoting any uncleared or unapproved use of our product. However, physicians may use these products in ways or circumstances other than those strictly within the scope of the regulatory approval or clearance. The use of our products for unauthorized purposes could arise from our sales personnel or distributors violating our policies by providing information or recommendations about such unauthorized uses. Consequently, claims may be asserted by the FDA or other enforcement agencies that we are not in compliance with applicable laws or regulations or have improperly

promoted our products for uncleared or unapproved uses. The FDA or such other agencies could require a recall of products or allege that our promotional activities misbrand or adulterate our products or violate other legal requirements, which could result in investigations, prosecutions, fines or other civil or criminal actions.
The FDA regulatory clearance process is expensive, time-consuming and uncertain, and the failure to obtain and maintain required regulatory clearances and approvals could prevent us from commercializing our products.
Before we can introduce a new device or a new use of or a claim for a cleared device in the United States, we must generally obtain clearance from the FDA through the 510(k) premarket notification process or approval through a PMA application, unless an exemption from premarket review or an alternative procedure, such as a de novo risk based classification or a humanitarian device exemption, applies. The FDA clearance and approval processes for medical devices are expensive, uncertain and time-consuming.
If human clinical trials of a medical device are required for FDA clearance or approval and the device presents a significant risk, the sponsor of the trial must file an IDE application with the FDA prior to commencing such trials in the U.S. Submission of an IDE application does not ensure that the IDE will become effective. If the IDE application is approved, there can be no assurance that the FDA will determine that the data derived from the trials support the safety and effectiveness of the device or warrant the continuation of clinical trials. For clinical trials involving a device that does not present a significant risk, the sponsor is not required to obtain FDA approval of an IDE, but the sponsor must obtain the review and approval of an institutional review board. Both significant risk and non-significant risk trials are subject to additional FDA regulations, including a requirement to obtain informed consent, reporting and recordkeeping requirements, and other requirements. We, the FDA, or the institutional review board, may suspend a clinical trial at any time for various reasons, including a belief that the risks to study subjects outweigh the anticipated benefits.
Changes to 510(k) cleared or PMA approved devices, including manufacturing changes, product enhancements and product line extensions, may require a new 510(k) clearance or approval of a PMA supplement. For devices marketed under an approved PMA, we must submit a PMA supplement to the FDA for review and approval prior to making a change to the device that affects the safety or effectiveness of the device, including changes to the design, manufacturing or labeling of the device. Likewise, for 510(k)-cleared devices, we must obtain new FDA 510(k) clearance when there is a major change or modification in the intended use, or a change or modification of the device that could significantly affect the safety or effectiveness of the device. In some cases, clinical data may be required to support a PMA supplement or 510(k) premarket notification for a device modification.
The FDA requires every manufacturer to make the determination regarding the need for a new 510(k) submission or a PMA supplement in the first instance, but the FDA may review the manufacturer’s decisions not to seek a new 510(k) or PMA supplement. We may make changes to our cleared products without seeking additional clearances or approvals if we determine such clearances or approvals are not necessary and document the basis for that conclusion. However, the FDA may disagree with our determination or may require additional information, including clinical data, to be submitted before a determination is made, in which case we may be required to delay the introduction and marketing of our modified products, redesign our products, conduct clinical trials to support any modifications and pay significant regulatory fines or penalties. In addition, the FDA may not approve or clear our products for the indications that are necessary or desirable for successful commercialization.
There is no assurance that we will be able to obtain the necessary regulatory clearances or approvals for any product on a timely basis or at all. Further, the FDA may change its clearance and approval policies, adopt additional regulations or revise existing regulations, or take other actions which may prevent or delay approval or clearance of our products under development or impact our ability to modify our currently cleared products on a timely basis. Delays in receipt of, or failure to obtain, regulatory clearances for any product enhancements or new products we develop would result in delayed or no realization of revenue from such product enhancements or new products and in substantial additional costs, which could decrease our profitability.
In addition, we are required to continue to comply with applicable FDA and other regulatory requirements once we have obtained clearance or approval for a product. We cannot assure you that we will successfully maintain the clearances or approvals we have received or may receive in the future. The loss of previously received clearances or approvals, or the failure to comply with existing or future regulatory requirements could also have a material adverse effect on our business.
Our products may cause or contribute to adverse medical events that we are required to report to the FDA or other governmental authorities, and if we fail to do so, we may be subject to sanctions that may materially harm our business.
Our products are subject to medical device reporting regulations, which require us to report to the FDA any information that reasonably suggests one of our products may have caused or contributed to a death or serious injury, or one of our products malfunctioned and, if the malfunction were to recur, this device or a similar device that we market would be likely to cause or

contribute to a death or serious injury. Our obligation to report under the medical device reporting regulations is triggered on the date on which we become aware of information that reasonably suggests a reportable adverse event occurred. We may fail to report adverse events of which we become aware within the prescribed timeframe. We may also fail to recognize that we have become aware of a reportable adverse event, especially if it is not reported to us as an adverse event or if it is an adverse event that is unexpected or if the product characteristic that caused the adverse event is removed in time from our products. If we fail to comply with our medical device reporting obligations, the FDA could issue warning letters or untitled letters, take administrative actions, commence criminal prosecution, impose civil monetary penalties, demand or initiate a product recall, seize our products, or delay the clearance of our future products.
We generally offer a limited warranty for the return of product due to defects in quality and workmanship. We attempt to estimate our potential liability for future product returns and establish reserves on our financial statements in amounts that we believe will be sufficient to address our warranty obligations; however, our actual liability for product returns may significantly exceed the amount of our reserves. If we underestimate our potential liability for future product returns, or if unanticipated events result in returns that exceed our historical experience, our financial condition and operating results could be materially harmed.
We may be unable to accurately forecast customer demand for our products and manage our inventory.
To ensure adequate supply, we must forecast our inventory needs and place orders with our suppliers based on estimates of future demand for particular products. Our ability to accurately forecast demand for our products could be negatively affected by many factors, including our failure to accurately manage our expansion strategy and customer acceptance of new products, product introductions by our competitors, an increase or decrease in customer demand for our products or for products of our competitors, unanticipated changes in general market conditions or regulatory matters and weakening of economic conditions or consumer confidence in future economic conditions. Inventory levels in excess of customer demand may result in inventory write-downs or write-offs, which would impact our gross margin. Conversely, if we underestimate customer demand for our products, our manufacturing facilities may not be able to deliver products to meet our order requirements, which could damage our reputation and customer relationships.
Our forecasts of customer demand and related decisions that we make about production levels may take into account potential opportunities created by regulatory issues, supply disruptions or other challenges experienced by our competitors. We generally do not know the extent and cannot predict the duration of these challenges experienced by our competitors. As a result, our estimates about related increased demand for our products are inherently uncertain and subject to change. If our estimates incorrectly forecast the extent or duration of this increased demand, or the product types to which it relates, our revenues, margins and earnings could be adversely affected.
