MERIT MEDICAL SYSTEMS, INC. AND SUBSIDIARIES

CONDENSED NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

(Unaudited)

1. Basis of Presentation. The interim consolidated financial statements of Merit Medical Systems, Inc. ("Merit," "we" or "us") for the three and six-month periods ended June 30, 2017 and 2016 are not audited. Our consolidated financial statements are prepared in accordance with the requirements for unaudited interim periods and, consequently, do not include all disclosures required to be made in conformity with accounting principles generally accepted in the United States of America. In the opinion of our management, the accompanying consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of our financial position as of June 30, 2017 and December 31, 2016, and our results of operations and cash flows for the three and six-month periods ended June 30, 2017 and 2016. The results of operations for the three and six-month periods ended June 30, 2017 and 2016 are not necessarily indicative of the results for a full-year period. These interim consolidated financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K (the "2016 Form 10-K") for the year ended December 31, 2016, which was filed with the Securities and Exchange Commission (the "SEC") on March 1, 2017.

2. Inventories. Inventories at June 30, 2017 and December 31, 2016 consisted of the following (in thousands):

	June 30,		December 31,
	2017		2016
Finished goods	$	75,971	$	63,852
Work-in-process	15,572		11,008
Raw materials	45,141		45,835
Total	$	136,684	$	120,695

3. Stock-Based Compensation. Stock-based compensation expense before income tax expense for the three and six-month periods ended June 30, 2017 and 2016, consisted of the following (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,
	2017		2016		2017		2016
Cost of goods sold	$	168	$	141	$	264	$	264
Research and development	100		54		152		96
Selling, general, and administrative	846		591		1,275		1,050
Stock-based compensation expense before taxes	$	1,114	$	786	$	1,691	$	1,410

As of June 30, 2017, the total remaining unrecognized compensation cost related to non-vested stock options, net of expected forfeitures, was approximately $17.3 million and is expected to be recognized over a weighted average period of 3.87 years.

During the three and six-month periods ended June 30, 2017, we granted stock-based awards representing approximately 1.28 million shares of our common stock. During the three and six-month periods ended June 30, 2016, we granted stock-based awards representing 220,875 and 784,375 shares of our common stock, respectively. We use the Black-Scholes methodology to value the stock-based compensation expense for options. In applying the Black-Scholes methodology to the options granted during the six-month periods ended June 30, 2017 and 2016, the fair value of our stock-based awards granted was estimated using the following assumptions for the periods indicated below:

	Six months ended June 30,
	2017	2016
Risk-free interest rate	1.77% - 1.79%	1.25% - 1.40%
Expected option life	5.0 years	5.0 years
Expected dividend yield	—%	—%
Expected price volatility	33.81% - 34.03%	36.50% - 37.06%

For the purpose of the foregoing analysis, 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 option. 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

9

historical volatility of our stock price over the corresponding expected option life 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.

4. Earnings Per Common Share (EPS). The computation of weighted average shares outstanding and the basic and diluted earnings per common share for the following periods consisted of the following (in thousands, except per share amounts):

	Three Months					Six Months
	Net Income		Shares	Per Share Amount		Net Income		Shares	Per Share Amount
Period ended June 30, 2017:
Basic EPS	$	9,483	49,957	$	0.19	$	24,286	47,406	$	0.51
Effect of dilutive stock options and warrants			1,231					1,110
Diluted EPS	$	9,483	51,188	$	0.19	$	24,286	48,516	$	0.50
Stock options excluded from the calculation of common stock equivalents as the impact was anti-dilutive			1,007					552
Period ended June 30, 2016:
Basic EPS	$	7,290	44,308	$	0.16	$	11,641	44,297	$	0.26
Effect of dilutive stock options and warrants			395					350
Diluted EPS	$	7,290	44,703	$	0.16	$	11,641	44,647	$	0.26
Stock options excluded from the calculation of common stock equivalents as the impact was anti-dilutive			1,207					1,093

5. Acquisitions. On May 23, 2017, we paid $2.5 million to acquire 182,000 shares of preferred stock of Fusion Medical, Inc. ("Fusion"), a developer of medical devices designed for clot removal. The shares of preferred stock we acquired, which represent an ownership interest of approximately 19.5%, have been accounted for as an equity method investment of $2.5 million reflected within other assets in the accompanying consolidated balance sheets because we may be deemed to exercise significant influence over the operations of Fusion.

On May 19, 2017, we entered into a business purchase agreement with Sugan Co, Ltd. ("Sugan"), a Japanese medical device distributor. Pursuant to this agreement, we terminated our distributor agreement with Sugan and acquired the customer list Sugan used in the distribution of our products in Japan. The consideration attributed to the customer list was approximately $1.1 million payable on or before December 31, 2017. The customer list is recorded as an other intangible asset and the amount due to Sugan is recorded in accrued expenses within the accompanying consolidated balance sheets. We intend to amortize the customer list on an accelerated basis over five years.

On May 1, 2017, we entered into an asset purchase agreement with Lazarus Medical Technologies, LLC to acquire rights to the patented technology for the Repositionable Chest Tube^TM and related devices. As of June 30, 2017, we had paid $570,000 in connection with this agreement. We are obligated to pay an additional $750,000 if certain milestones set forth in the agreement are reached. We are also required to pay royalties equal to 6% of net sales throughout the term of the agreement. We accounted for this transaction as an asset purchase. We recorded the amount paid upon closing as a license agreement intangible asset, which we intend to amortize over 15 years.

On May 1, 2017, we entered into an agreement and plan of merger with Vascular Access Technologies, Inc. ("VAT"), pursuant to which we acquired the SAFECVAD™ device. We accounted for this acquisition as a business combination. The purchase price for the business was $5.0 million. We also recorded $4.9 million of contingent consideration related to royalties payable to VAT pursuant to the agreement. The following table summarizes the preliminary purchase price allocated to the net assets acquired and liabilities assumed (in thousands):

10

Net Assets Acquired
Intangibles
Developed technology	7,800
In-process technology	850
Goodwill	4,323
Deferred tax liabilities	(3,073		)
Total net assets acquired	$	9,900

We are amortizing the developed technology intangible asset over fifteen years. 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 VAT acquisition, which are included in selling, general and administrative expenses in the accompanying consolidated statements of income, were not material.

On January 31, 2017, we signed a purchase agreement with Argon Medical Devices, Inc. ("Argon") to acquire Argon’s critical care division, including a manufacturing facility in Singapore, the related commercial operations in Europe and Japan, and certain inventories and intellectual property rights within the United States. We made an initial payment of approximately $10.9 million and received a subsequent reduction to the purchase price of approximately $797,000 related to a working capital adjustment according to the terms of the purchase agreement. We accounted for the acquisition as a business combination.

Acquisition-related costs associated with the acquisition of the Argon critical care division during the three and six-month periods ended June 30, 2017, which are included in selling, general and administrative expenses in the accompanying consolidated statements of income, were approximately $1.3 million and $2.4 million, respectively. The results of operations related to this acquisition have been included in our cardiovascular segment since the acquisition date. During the three and six-month periods ended June 30, 2017, our net sales of Argon products were approximately $11.7 million and $19.0 million, respectively. It is not practical to separately report the earnings related to the Argon acquisition, as we cannot split out sales costs related solely to the products we acquired from Argon, principally because our sales representatives sell multiple products (including the products we acquired from Argon) in our cardiovascular business segment.

The assets and liabilities in the initial purchase price allocation for the Argon 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 preliminary purchase price allocated to the net tangible and intangible assets acquired and liabilities assumed (in thousands):

	Gain on bargain purchase (1)	(12,243		)	669			(11,574		)
	Total purchase price	$	10,897		$	(797	)	$	10,100
(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 for the three and six-month periods ended June 30, 2017, and includes a negative adjustment of $669,000 in the three-month period ended June 30, 2017. We believe the reason for the provisional 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.
(2)	Amounts represent adjustments to the preliminary purchase price allocation first presented in our March 31, 2017 Form 10-Q resulting from our ongoing activities, including reassessment of the assets acquired and liabilities assumed, with respect to finalizing our purchase price allocation for this acquisition.

With respect to the Argon 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 currently 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.

Given the timing of this acquisition, which closed during the first quarter of 2017, as well as the complexity of the acquisition, the entire purchase price allocation disclosed herein (as well as the gain on bargain purchase) is considered provisional at this time and is subject to adjustment to reflect information obtained about factors and circumstances that existed as of the acquisition date that if known would have affected the measurement of the amounts recognized as of that date. We are currently reassessing whether we have fully identified all the assets acquired and the liabilities assumed, and the measurement period remains open.

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, which are included in selling, general and administrative expenses in the accompanying consolidated statements of income, were not material. The results of operations

12

related to this acquisition have been included in our cardiovascular segment since the acquisition date. During the three and six-month periods ended June 30, 2017, our net sales of the products acquired from Catheter Connections were approximately $2.5 million and $4.3 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 preliminarily allocated as follows (in thousands):

		Preliminary Allocation			Adjustments (1)			Revised Preliminary Allocation
	Assets Acquired
	Trade receivables	$	952		$	7		$	959
	Inventories	2,244			(87		)	2,157

	Net assets acquired	$	38,000		$	—		$	38,000
(1)	Amounts represent adjustments to the preliminary purchase price first presented in our Quarterly Report on Form 10-Q for the Quarter Ended March 31, 2017, resulting from our ongoing activities with respect to finalizing our purchase price allocation for this acquisition. The larger adjustments primarily relate to the valuation of the acquired intangible assets.

We are amortizing the Catheter Connections developed technology asset over 12 years, the related trademarks over 10 years, and the associated customer list 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 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. In the three-month period ended December 31, 2016, we negotiated the final net working capital adjustment resulting in a reduction to the purchase price of approximately $1.1 million. As a result, we recorded measurement period adjustments to reduce inventories by approximately $89,000, reduce property and equipment by approximately $109,000, reduce goodwill by approximately $1.2 million, reduce accrued expenses by approximately $407,000 and increase the associated deferred tax liabilities by approximately $113,000. The measurement period for this acquisition is now closed. Under GAAP, measurement period adjustments are recognized on a prospective basis in the period of change, instead of restating prior periods. There was no material impact to reported earnings in connection with these measurement period adjustments.

Acquisition-related costs associated with the DFINE acquisition during the year ended December 31, 2016, which were included in selling, general and administrative expenses in the consolidated statements of income included in the 2016 Form 10-K, 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 year ended December 31, 2016, our net sales of DFINE products were approximately $13.5 million. It is not practical to separately report the earnings related to the DFINE acquisition, as we cannot split out sales costs

13

related solely to the DFINE products, principally because our sales representatives sell 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):

Assets Acquired
Trade receivables	$	4,054
Other receivables	6
Inventories	8,585
Prepaid expenses	630
Property and equipment	1,630
Other long-term assets	145
Intangibles
Developed technology	67,600
Customer lists	2,400
Trademarks	4,400
Goodwill	24,818
Total assets acquired	114,268
Liabilities Assumed
Trade payables	(1,790		)
Accrued expenses	(5,298		)
Deferred income tax liabilities - current	(701		)
Deferred income tax liabilities - noncurrent	(10,844		)
Total liabilities assumed	(18,633		)
Net assets acquired, net of cash received of $1,327	$	95,635

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 equipment	290
Intangibles
Developed technology	12,100
Trademarks	700
Customers Lists	400
Goodwill	2,555
Total assets acquired	$	18,500

14

We are amortizing the developed HeRO Graft technology asset over ten 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 9.82 years. Acquisition-related costs related to the HeRO Graft device and other related assets during the year ended December 31, 2016, which were included in selling, general and administrative expenses in the consolidated statements of income included in the 2016 Form 10-K, were not material. The results of operations related to this acquisition have been included in our cardiovascular segment since the acquisition date. During the year ended December 31, 2016, our net sales of the products acquired from CryoLife were approximately $7.1 million. It is not practical to separately report the earnings related to the products acquired from CryoLife, as we cannot split out sales costs related solely to those products, principally because our sales representatives sell multiple products (including the HeRO Graft device) in the cardiovascular business segment.

The following table summarizes our consolidated results of operations for the three-month period ended June 30, 2016 and the six-month periods ended June 30, 2017 and 2016, as well as unaudited pro forma consolidated results of operations as though the DFINE acquisition had occurred on January 1, 2015 and the acquisition of the Argon critical care division had occurred on January 1, 2016 (in thousands, except per share amounts):

	Three Months Ended				Six Months Ended				Six Months Ended
	June 30, 2016				June 30, 2017				June 30, 2016
	As Reported		Pro Forma		As Reported		Pro Forma		As Reported		Pro Forma
Net Sales	$	151,071	$	170,878	$	357,618	$	360,378	$	289,148	$	327,268

* The pro forma results for the three-month period ended June 30, 2017 are not included in the table above because the operating results for the DFINE and Argon critical care division acquisitions were included in our consolidated statements of income for this period.

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, interest expense on long-term debt and changes in the timing of the recognition of the gain on bargain purchase. The pro forma information should not be considered indicative of actual results that would have been achieved if the DFINE acquisition had occurred on January 1, 2015 and the acquisition of the Argon critical care division had occurred on January 1, 2016, or results that may be obtained in any future period. The pro forma consolidated results of operations do not include the VAT, Catheter Connections or HeRO Graft acquisitions as we do not deem the pro forma effect of these transactions to be material.

6. 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"), and interventional oncology and spine devices. Our endoscopy segment consists of gastroenterology and pulmonology medical device products which assist in the palliative treatment of expanding esophageal, tracheobronchial and biliary strictures caused by malignant tumors. We evaluate the performance of our operating segments based on operating income. 

Financial information relating to our reportable operating segments and reconciliations to the consolidated totals for the three and six-month periods ended June 30, 2017 and 2016, are as follows (in thousands):

	Three Months Ended June 30,				Six Months Ended June 30,

7. New Financial Accounting Standards.

Recently Adopted

In January 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates the requirement to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under these amendments, goodwill impairment testing will be performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. We adopted ASU 2017-04 effective January 1, 2017 on a prospective basis, and it did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which provides guidance to entities to assist with evaluating when a set of transferred assets and activities is a business and provides a screen to determine when a set is not a business. Under the new guidance, when substantially all the fair value of gross assets acquired (or disposed of) is concentrated in a single identifiable asset, or group of similar assets, the assets acquired would not represent a business. Also, to be considered a business, an acquisition would have to include an input and a substantive process that together significantly contribute to the ability to produce outputs. We adopted ASU 2017-01 effective January 1, 2017 on a prospective basis. The implementation of ASU 2017-01 did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which requires companies to record excess tax benefits and deficiencies in income rather than the current requirement to record them through equity. ASU 2016-09 also allows companies the option to recognize forfeitures of share-based awards when they occur rather than the previous requirement to make an estimate upon the grant of the awards. We adopted ASU 2016-09 effective January 1, 2017 on a prospective basis and, as such, no prior periods were adjusted. In accordance with the new standard and prospectively since the date we adopted ASU 2016-09, excess tax benefits from stock-based compensation are reported as an income tax benefit in our consolidated statements of income (see Note 8).

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which requires all deferred tax assets and deferred tax liabilities to be presented as noncurrent within a classified balance sheet. We adopted ASU 2015-17 effective January 1, 2017 on a prospective basis and did not reclassify presentation of prior year balances. The adoption of this standard did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. ASU 2015-11 requires that inventory be measured at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Inventory measured using last-in, first-out or the retail inventory method are excluded from the scope of ASU 2015-11, which is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The implementation of ASU 2015-11 did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

Not Yet Adopted

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other than Inventory, which requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. ASU 2016-16 will be effective for us on January 1, 2018. We are currently evaluating the anticipated impact of adopting ASU 2016-16 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. ASU 2016-15 will be effective for us on January 1, 2018 with early adoption permitted. We do not presently anticipate that the adoption of ASU 2016-15 will have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases, 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

16

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.

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. ASU 2016-01 will be effective for us on January 1, 2018. Early adoption is not permitted except for the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income. Upon adoption of ASU 2016-01, an entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance is effective. We do not presently anticipate that the adoption of ASU 2016-01 will have a material impact on our financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), to update the financial reporting requirements for revenue recognition. Topic 606 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The guidance is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. This guidance is effective for us beginning on January 1, 2018, and entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. We have not yet reached a conclusion on whether we will adopt this new standard on a prospective or retrospective basis.

We are concluding the assessment phase of implementing this guidance. We have evaluated each of the five steps in Topic 606, which are as follows: 1) Identify the contract with the customer; 2) Identify the performance obligations in the contract; 3) Determine the transaction price; 4) Allocate the transaction price to the performance obligations; and 5) Recognize revenue when (or as) performance obligations are satisfied. Our preliminary conclusion is that we expect to identify similar performance obligations under ASC Topic 606 as compared with deliverables and separate units of account previously identified. As a result, we expect the timing of our revenue to remain largely the same in comparison to the current revenue recognition guidance. There are also certain considerations related to internal control over financial reporting that are associated with implementing Topic 606. We are currently evaluating our control framework for revenue recognition and identifying any changes that may need to be made in response to the new guidance. Disclosure requirements under the new guidance in Topic 606 have been significantly expanded in comparison to the disclosure requirements under the current guidance. Designing and implementing the appropriate controls over gathering and reporting the information required under Topic 606 is currently in process.

8. Income Taxes. Our overall effective tax rate for the three months ended June 30, 2017 and 2016 was 16.2% and 26.1%, respectively, which resulted in a provision for income taxes of approximately $1.8 million and $2.6 million, respectively. Our overall effective tax rate for the six months ended June 30, 2017 and 2016 was 9.4% and 26.2%, respectively, which resulted in a provision for income taxes of approximately $2.5 million and $4.1 million, respectively. A higher mix of earnings from our foreign operations, primarily in Ireland, which are taxed at lower rates than our U.S. operations and a discrete tax benefit related to share-based payment awards due to the application of ASU No. 2016-09 decreased our effective income tax rates for both periods, when compared to the prior year periods. A nontaxable gain on the bargain purchase relating to the acquisition of the critical care division of Argon also decreased the effective income tax rate for the six-month period ended June 30, 2017, when compared to the corresponding period of 2016.

9. Revolving Credit Facility and Long-term Debt. Our outstanding debt obligations as of June 30, 2017 and December 31, 2016, consisted of the following (in thousands):

	June 30, 2017			December 31, 2016
2016 Term loan	$	90,000		$	145,000
2016 Revolving credit loans	145,500			180,000
2017 Debt facility	6,969			—
Less debt issuance costs	(557		)	(627		)
Total debt	241,912			324,373
Less current portion	16,969			10,000
Long-term portion	$	224,943		$	314,373

2017 Debt Facility

On February 23, 2017, we entered into a 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 matures on February 1, 2018, with an extension available at our option, subject to certain conditions. The loan agreement bears interest at the three-month London Inter-Bank Offered Rate (“LIBOR”) plus 1.0%, which resets quarterly. The loan is secured by assets equal to the currently outstanding loan balance. The loan contains covenants, representations and warranties and other terms customary for loans of this nature. As of June 30, 2017, our interest rate on the loan was a variable rate of 2.12%.

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, 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 and on March 20, 2017 to allow flexibility in how we apply net proceeds received from equity issuances to prepay outstanding indebtedness.

The Second Amended Credit Agreement provides for a term loan of $150 million and a revolving credit commitment up to an aggregate amount of $275 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 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:

18

		Covenant Requirement
Consolidated Total Leverage Ratio (1)
	As of June 30, 2017	4.0 to 1.0
	July 1, 2017 through December 31, 2017	3.75 to 1.0
	January 1, 2018 through March 31, 2018	3.5 to 1.0
	April 1, 2018 and thereafter	3.25 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, 2017, we believe we were in compliance with all covenants set forth in the Second Amended Credit Agreement.

As of June 30, 2017, we had outstanding borrowings of approximately $235.5 million under the Second Amended Credit Agreement, with available borrowings of approximately $129.5 million, based on the leverage ratio required pursuant to the Second Amended Credit Agreement. Our interest rate as of June 30, 2017 was a fixed rate of 2.23% on $127.5 million and a fixed rate of 2.37% on $47.5 million as a result of interest rate swaps (see Note 10), and a variable floating rate of 2.48% on $60.5 million. Our interest rate as of December 31, 2016 was a fixed rate of 2.98% on $130.0 million and 3.12% on $45.0 million as a result of interest rate swaps and a variable floating rate of 2.77% on approximately $150.0 million.

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 programs 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

19

taxes, in accumulated other comprehensive income (loss), a component of stockholders’ equity in the accompanying consolidated balance sheets. For the ineffective portions of qualifying hedges, the change in fair value is recorded through earnings in the period of change. 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.

Derivatives Designated as Cash Flow Hedges

On December 19, 2012, we entered into a pay-fixed, receive-variable interest rate swap having an initial notional amount of $150 million with Wells Fargo to fix the one-month LIBOR rate at 0.98%. The variable portion of the interest rate swap is tied to the one-month LIBOR rate (the benchmark interest rate). 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 on a monthly basis. The notional amount of the interest rate swap is reduced quarterly by 50% of the minimum principal payment due under the terms of our Second Amended Credit Agreement. The interest rate swap is scheduled to expire on December 19, 2017.

On August 5, 2016, we entered into a pay-fixed, receive-variable interest rate swap having an initial notional amount of $42.5 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 notional amount of the interest rate swap increases quarterly by an amount equal to the decrease of the hedge entered into on December 19, 2012, up to the amount of $175.0 million. The interest rate swap is scheduled to expire on July 6, 2021.

At June 30, 2017 and December 31, 2016, our interest rate swaps qualified as cash flow hedges. The fair value of our interest rate swaps at June 30, 2017 was an asset of approximately $4.5 million, which was partially offset by approximately $1.7 million in deferred taxes. The fair value of our interest rate swaps at December 31, 2016 was an asset of approximately $5.0 million, which was partially offset by approximately $1.9 million in deferred taxes.

Foreign Currency Risk. 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 Yuan Renminbi, Mexican Pesos, Brazilian Reals, Australian Dollars, Hong Kong Dollars, Swiss Francs, Swedish Krona, Canadian Dollars, Singapore Dollars, Japanese Yen, Korean Won, and Danish Krone. Our consolidated financial statements are denominated in, and our principal currency is, the U.S. Dollar. 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.

Derivatives 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 100 cash flow foreign currency hedges every month. As of June 30, 2017, 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):

20

Euro	EUR	8,375
Swiss Franc	CHF	1,448
Danish Krone	DKK	9,955
British Pound	GBP	3,355
Mexican Peso	MXN	83,325
Swedish Krona	SEK	13,930

Derivatives 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, 2017, 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):

Currency	Symbol	Forward Notional Amount

11. Fair Value Measurements. Our financial assets and (liabilities) carried at fair value measured on a recurring basis as of June 30, 2017 and December 31, 2016, consisted of the following (in thousands):

				Fair Value Measurements Using
	Total Fair			Quoted prices in		Significant other			Significant
	Value at			active markets		observable inputs			unobservable inputs

(1)    The fair value of the interest rate contracts is determined using Level 2 fair value inputs and is recorded as prepaid expenses and other assets (current) and other assets (long-term) in the consolidated balance sheets.

(2)    The fair value of the foreign currency contract assets (including those designated as hedging instruments and those not designated as hedging instruments) is determined using Level 2 fair value inputs and is recorded as prepaid expenses and other assets (current) and other assets (long-term) in the consolidated balance sheets.

(3)    The fair value of the foreign currency contract liabilities (including those designated as hedging instruments and those not designated as hedging instruments) is determined using Level 2 fair value inputs and is recorded as accrued expenses (current) and other long-term obligations in the consolidated balance sheets.

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 each reporting period with the change in fair value recognized within operating expenses in the accompanying consolidated statements of income. We measure the initial liability and re-measure the liability on a recurring basis using Level 3 inputs as defined under authoritative

23

guidance for fair value measurements. Changes in the fair value of our contingent consideration liability during the three and six-month periods ended June 30, 2017 and 2016, consisted of the following (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,
	2017			2016			2017			2016
Beginning balance	$	705		$	928		$	683		$	1,024
Contingent consideration liability recorded as the result of acquisitions (see Note 5)	4,900			—			4,900			—
Fair value adjustments recorded to income during the period	(18		)	(14		)	19			57
Contingent payments made	(15		)	(16		)	(30		)	(183		)
Ending balance	$	5,572		$	898		$	5,572		$	898

The recurring Level 3 measurement of our contingent consideration liabilities and contingent receivable includes the following significant unobservable inputs at June 30, 2017 and December 31, 2016 (amounts in thousands):

Contingent consideration asset or liability	Fair value at June 30, 2017		Valuation technique	Unobservable inputs	Range
Revenue-based payments	$	5,572	Discounted cash flow	Discount rate	9.9% - 15%
contingent liability				Probability of milestone payment	100%
				Projected year of payments	2017-2033
Contingent receivable	$	528	Discounted cash flow	Discount rate	10%
asset				Probability of milestone payment	57%
				Projected year of payments	2017-2019
Contingent consideration asset or liability	Fair value at December 31, 2016		Valuation technique	Unobservable inputs	Range
Revenue-based payments	$	683	Discounted cash flow	Discount rate	9.9% - 15%
contingent liability				Probability of milestone payment	100%
				Projected year of payments	2017-2028
Contingent receivable	$	528	Discounted cash flow	Discount rate	10%
asset				Probability of milestone payment	57%
				Projected year of payments	2017-2019

The contingent consideration liabilities 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 liabilities and contingent receivable could change in future periods based upon our ongoing evaluation of these significant unobservable inputs. We record any such change in fair value to operating expenses in our consolidated statements of income. As of June 30, 2017, approximately $5.5 million was included in other long-term obligations and $69,000 was included in accrued expenses in our consolidated balance sheet. As of December 31, 2016, approximately $595,000 was included in other long-term obligations and $88,000 was included in accrued expenses in our consolidated balance sheet. The cash 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 three and six-month periods ended June 30, 2017, we had losses of approximately $1,000, and $19,000, respectively, compared to losses of approximately $90,000 and $90,000 for the three and six-month periods ended June 30, 2016, respectively, related to the measurement of non-financial assets at fair value on a nonrecurring basis subsequent to their initial recognition.

24

The carrying amount of cash and cash equivalents, trade receivables, and trade payables approximate fair value because of the immediate, short-term maturity of these financial instruments. The carrying amount of long-term debt approximates fair value, as determined by borrowing rates estimated to be available to us for debt with similar terms and conditions. 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.

12. Goodwill and Intangible Assets. The changes in the carrying amount of goodwill for the six-month period ended June 30, 2017 were as follows (in thousands):

	2017
Goodwill balance at January 1	$	211,927
Effect of foreign exchange	1,686
Additions as the result of acquisitions	13,216
Goodwill balance at June 30	$	226,829

As of June 30, 2017, we had recorded $8.3 million of accumulated goodwill impairment charges. The goodwill balances as of June 30, 2017 and December 31, 2016, were related to our cardiovascular segment.

Other intangible assets at June 30, 2017 and December 31, 2016, consisted of the following (in thousands):

	June 30, 2017
	Gross Carrying Amount		Accumulated Amortization			Net Carrying Amount
Patents	$	15,192	$	(3,444	)	$	11,748

Royalty agreements	267		(267		)	—
Total	$	77,387	$	(30,048	)	$	47,339

Aggregate amortization expense for the three and six-month periods ended June 30, 2017 was approximately $6.2 million and $12.4 million, respectively. For the three and six-month periods ended June 30, 2016, aggregate amortization expense was approximately $4.0 million and $7.9 million, respectively.

Estimated amortization expense for the developed technology and other intangible assets for the next five years consists of the following as of June 30, 2017 (in thousands):

25

Year Ending December 31
Remaining 2017	$	12,679
2018	24,565

2020	23,079
2021	16,614

13. 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, contractual, and employment matters. We do not believe that any such actions are likely to be, individually or in the aggregate, material to our business, financial condition, results of operations or liquidity. However, in the event of unexpected further developments, it is possible that the ultimate resolution of these matters, or other similar matters, if unfavorable, 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.

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 2017. We have incurred, and anticipate that we will continue to incur, substantial costs in connection with the matter. We incurred approximately $3.7 million and $8.5 million of expenses for the three and six-month periods ended June 30, 2017, respectively, responding to the pending subpoena from the U.S. Department of Justice. We expect that these expenses will be in a similar range in subsequent periods and may potentially be higher, depending on the progress of the investigation and other factors beyond our control. 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.

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.

14. 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 $815,000 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).

OVERVIEW

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the consolidated financial statements and related condensed notes thereto, which are included in Part I of this Report.

We design, develop, manufacture and market single-use medical products for interventional and diagnostic procedures. For financial reporting purposes, we report our operations in two operating segments: cardiovascular and endoscopy. Our cardiovascular segment consists of cardiology and radiology devices, which assist in diagnosing and treating coronary arterial disease, peripheral vascular disease and other non-vascular diseases and includes embolotherapeutic, cardiac rhythm management ("CRM"), electrophysiology ("EP"), and interventional oncology and spine devices. Our endoscopy segment consists of gastroenterology and pulmonology devices which assist in the palliative treatment of expanding esophageal, tracheobronchial and biliary strictures caused by malignant tumors.

For the three-month period ended June 30, 2017, we reported sales of approximately $186.5 million, up approximately $35.5 million or 23.5%, over sales from the three-month period ended June 30, 2016 of approximately $151.1 million. For the six-month period ended June 30, 2017, we reported sales of approximately $357.6 million, up approximately $68.5 million or 23.7%, over sales for the six-month period ended June 30, 2016 of approximately $289.1 million.

Gross profit as a percentage of sales increased to 45.1% for the three-month period ended June 30, 2017 as compared to 44.3% for the three-month period ended June 30, 2016. Gross profit as a percentage of sales increased to 44.8% for the six-month period ended June 30, 2017 as compared to 43.9% for the six-month period ended June 30, 2016.

Net income for the three-month period ended June 30, 2017 was approximately $9.5 million, or $0.19 per share, as compared to $7.3 million, or $0.16 per share, for the three-month period ended June 30, 2016. For the six-month period ended June 30, 2017, net income was approximately $24.3 million, or $0.50 per share, as compared to $11.6 million, or $0.26 per share, for the six-month period ended June 30, 2016.

We anticipate that our business in 2017 will continue to be impacted by the trends identified in the 2016 Form 10-K under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Overview.”

Our cardiovascular sales for the three-month period ended June 30, 2017 were approximately $179.7 million, up 23.5%, when compared to the corresponding period for 2016 of approximately $145.5 million. Sales for the three-month period ended June 30, 2017 were favorably affected by increased sales of our stand-alone devices (particularly our Map™, Medallion, Vaclock and Ensnare® products, as well as new sales from our acquisitions the DFINE, Argon and Catheter Connections product lines) of approximately $25.2 million, up 54.3% and catheters (particularly our SwiftNINJA product line, Concierge® Guiding Catheters, and our Maestro® microcatheters) of approximately $3.1 million, up 10.8% and CRM/EP of approximately $1.9 million, up 19.3%. Our cardiovascular sales increased approximately $66.5 million, or 23.9%, for the six-month period ended June 30, 2017, on sales of approximately $344.5 million, compared to sales of approximately $278.1 million for the corresponding period of 2016. Sales for the six-month period ended June 30, 2017 were favorably affected by increased sales of our stand-alone devices (particularly our Map, Medallion, Vaclock, HeRO Graft and Ensnare products, as well as new sales from our acquisitions the DFINE, Argon and Catheter Connections product lines) of approximately $46 million, up 51.2% and catheters (particularly our SwiftNINJA product line, Concierge guiding catheters, Preforma® vessel-sizing catheters, and Maestro microcatheters) of approximately $9.0 million, up 17% and CRM/EP of approximately $4.9 million, up 28.1%.

Our endoscopy sales for the three-month period ended June 30, 2017 were approximately $6.8 million, up 22.9%, when compared to sales in the corresponding period of 2016 of approximately $5.5 million. Our endoscopy sales increased 18.2% for the six-month period ended June 30, 2017, on sales of approximately $13.1 million, when compared to sales for the corresponding period

31

of 2016 of approximately $11.1 million. The increase in both periods was primarily related to an increase in sales of our EndoMAXX™ fully covered esophageal stent, as well as the introduction of our Elation® balloon dilator.

Gross Profit. Gross profit as a percentage of sales increased to 45.1% for the three-month period ended June 30, 2017, compared to 44.3% for the corresponding period of 2016. Gross profit as a percentage of sales increased to 44.8% for the six-month period ended June 30, 2017, compared to 43.9% for the six-month period ended June 30, 2016. The increase was primarily due to changes in product mix and increased efficiencies gained from our operations team.

Operating Expenses. Selling, general, and administrative ("SG&A") expenses increased approximately $13.8 million, or 31.5%, for the three-month period ended June 30, 2017, compared to the three-month period ended June 30, 2016. As a percentage of sales, SG&A expenses increased to 30.8% of sales for the three-month period ended June 30, 2017, compared to 28.9% of sales for the three-month period ended June 30, 2016. SG&A expenses increased approximately $29.8 million, or 34.9%, for the six-month period ended June 30, 2017, compared to the six-month period ended June 30, 2016. As a percentage of sales, SG&A expenses increased to 32.2% of sales for the six-month period ended June 30, 2017, compared to 29.5% of sales for the six-month period ended June 30, 2016. The increase in SG&A expense was primarily related to acquisition and integration costs for our acquisitions of the critical care division of Argon and the assets of Catheter Connections, legal expenses of approximately of $3.7 million and $8.5 million for the three and six months ended June 30, 2017, respectively, incurred in responding to the pending subpoena from the U.S. Department of Justice, increased headcount, increased amortization, and foreign market expansion.

Research and Development Expenses. Research and development expenses for the three-month period ended June 30, 2017 were approximately $13.3 million, up 16.5% when compared to research and development expenses in the corresponding period of 2016 of approximately $11.4 million. Research and development expenses were approximately $25.8 million, up 17.4%, when compared to research and development expenses in the corresponding period of 2016 of approximately $22.0 million. This increase was largely due to hiring additional research and development personnel to support various new product developments.

Operating Income. The following table sets forth our operating income by business segment for the three and six-month periods ended June 30, 2017 and 2016 (in thousands):

	Three Months Ended June 30,		Six Months Ended June 30,
	2017	2016	2017	2016
Operating Income
Cardiovascular	11,545	10,880	15,549	17,529
Endoscopy	1,817	701	3,422	1,759
Total operating income	13,362	11,581	18,971	19,288

Cardiovascular Operating Income. Our cardiovascular operating income for the three-month period ended June 30, 2017 was approximately $11.5 million, compared to our cardiovascular operating income of approximately $10.9 million for the three-month period ended June 30, 2016. The increase in cardiovascular operating income was primarily related to increased sales and gross margin improvements, which were partially offset by headcount additions, $3.7 million of legal expenses incurred in responding to the pending subpoena from the U.S. Department of Justice, and acquisition and integration-related costs. Our cardiovascular operating income for the six-month period ended June 30, 2017 was approximately $15.5 million, compared to our cardiovascular operating income of approximately $17.5 million for the six-month period ended June 30, 2016. The decrease in cardiovascular operating income between the six months ended June 30, 2017 and the six months ended June 30, 2016 was primarily related to headcount additions, $8.5 million of legal expenses incurred in responding to the pending subpoena from the U.S. Department of Justice, and acquisition and integration-related costs, which were partially offset by increased sales and gross margin improvements.

Endoscopy Operating Income. Our endoscopy operating income for the three-month period ended June 30, 2017 was approximately $1.8 million, compared to approximately $701,000 for the three-month period ended June 30, 2016. Our endoscopy operating income for the six-month period ended June 30, 2017 was approximately $3.4 million, compared to approximately $1.8 million for the six-month period ended June 30, 2016. The increases in endoscopy operating income for the three and six-months ended June 30, 2017 were primarily the result of higher sales and gross margin improvements, partially offset by higher SG&A expenses.

Income Taxes. Our overall effective tax rate for the three months ended June 30, 2017 and 2016 was 16.2% and 26.1%, respectively, which resulted in a provision for income taxes of approximately $1.8 million and $2.6 million, respectively. Our overall effective tax rate for the six months ended June 30, 2017 and 2016 was 9.4% and 26.2%, respectively, which resulted in a provision for income taxes of approximately $2.5 million and $4.1 million, respectively. A higher mix of earnings from our foreign operations, primarily in Ireland, which are taxed at lower rates than our U.S. operations and a discrete tax benefit related

32

to share-based payment awards due to the application of ASU No. 2016-09 decreased our effective income tax rates for both periods, when compared to the prior year periods. A nontaxable gain on bargain purchase relating to the acquisition of the critical care division of Argon also decreased the effective income tax rate for the six-month period ended June 30, 2017, when compared to the corresponding period of 2016.

Other Income (Expense) - Net. Our other income (expense) for the three-month periods ended June 30, 2017 and 2016 was expense of approximately $(2.0) million and $(1.7) million, respectively. The change in other income (expense) was principally the result of a reduction to the bargain purchase related to the acquisition of the Argon critical care division of approximately $669,000, which was offset by lower interest expense due to lower average debt balances.

Our other income (expense) for the six-month periods ended June 30, 2017 and 2016 was income of approximately $7.8 million and expense of approximately $(3.5) million, respectively. The change in other income (expense) was principally the result of a gain on bargain purchase related to the acquisition of the Argon critical care division of approximately $11.6 million.

Net Income. Our net income for the three-month periods ended June 30, 2017 and 2016 was approximately $9.5 million and $7.3 million, respectively. Our net income for the six-month periods ended June 30, 2017 and 2016 was approximately $24.3 million and $11.6 million, respectively. The increase in net income for the three months ended June 30, 2017 compared to the three months ended June 30, 2016 was primarily due to increased sales, gross margin improvement and a discrete tax benefit related to share-based payment awards due to application of ASU No. 2016-09 which decreased our effective income tax rate. The increase in net income for the six months ended June 30, 2017 compared to the six months ended June 30, 2016 was primarily due to the gain on bargain purchase of approximately $11.6 million related to the acquisition of the Argon critical care division and and a discrete tax benefit related to share-based payment awards due to application of ASU No. 2016-09 which decreased our effective income tax rate, which was partially offset by approximately $8.5 million of legal expenses incurred in responding to the pending subpoena from the U.S. Department of Justice and acquisition and integration-related costs.

LIQUIDITY AND CAPITAL RESOURCES

Capital Commitments, Contractual Obligations and Cash Flows

At June 30, 2017 and December 31, 2016, we had cash and cash equivalents of approximately $37.7 million and $19.2 million respectively, of which $36.7 million and $18.4 million, respectively, were held by foreign subsidiaries. For each of our foreign subsidiaries, we make an evaluation as to whether the earnings are intended to be repatriated to the United States or held by the foreign subsidiary for permanent reinvestment. The cash held by our foreign subsidiaries for permanent reinvestment is used to fund the operating activities of our foreign subsidiaries and for further investment in foreign operations. A deferred tax liability has been accrued for the earnings that are available to be repatriated to the United States.

In addition, cash held by our subsidiary in China is subject to local laws and regulations that require government approval for the transfer of such funds to entities located outside of China. As of June 30, 2017 and December 31, 2016, we had cash and cash equivalents of approximately $12.7 million and $9.5 million, respectively, held by our subsidiary in China.

Cash flows provided by operating activities. Cash provided by operating activities during the six-month periods ended June 30, 2017 and 2016 was primarily the result of net income excluding non-cash items offset by shifts in working capital. Our working capital as of June 30, 2017 and December 31, 2016 was approximately $180.6 million and $155.1 million, respectively. The increase in working capital as of June 30, 2017 compared to December 31, 2016 was primarily the result of increases in cash, trade receivables and inventories, which were partially offset by a decrease in current deferred tax assets and an increase in trade payables, accrued expenses and the current portion of long-term debt. As of June 30, 2017 and December 31, 2016, we had a current ratio of 2.57 to 1 and 2.76 to 1, respectively.

During the six-month period ended June 30, 2017, our inventory balance increased approximately $16.0 million, from approximately $120.7 million as of December 31, 2016 to approximately $136.7 million as of June 30, 2017. The increase in the inventory balance was due, in large part, to the acquisition of Catheter Connections and the critical care division of Argon. The trailing twelve-month inventory turns as of June 30, 2017 decreased to 3.04, compared to 3.09 as of June 30, 2016.

Cash flows provided by financing activities. Cash provided by financing activities for the six-month period ended June 30, 2017 was approximately $57.6 million, compared to cash provided by financing activities of approximately $24.7 million for the six-month period ended June 30, 2016, a change of approximately $32.9 million. The increase in cash provided by financing activities was primarily the result of our public equity offering of 5,175,000 shares of common stock from which we received proceeds of approximately $136.6 million, which is net of approximately $8.8 million in underwriting discounts and commissions and

33

approximately $815,000 in other direct costs incurred and paid by us in connection with the offering. This increase was partially offset by an increase in net payments on our long-term debt.

On February 23, 2017, we entered into a loan agreement with HSBC Bank, whereby HSBC Bank agreed to provide us with a loan in the amount of approximately $7.0 million. The loan matures on February 1, 2018, with an extension available at our option, subject to certain conditions. The loan agreement bears interest at the three-month LIBOR rate plus 1.0%, and resets quarterly. The loan is secured by assets equal to the currently outstanding loan balance. The loan contains covenants, representations and warranties and other terms customary for loans of this nature. Our interest rate as of June 30, 2017 was a variable rate of 2.12%.

Our Second Amended Credit Agreement provides for a term loan of $150 million and a revolving credit commitment up to an aggregate amount of $275 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 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)
	As of June 30, 2017	4.0 to 1.0
	July 1, 2017 through December 31, 2017	3.75 to 1.0
	January 1, 2018 through March 31, 2018	3.5 to 1.0
	April 1, 2018 and thereafter	3.25 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, 2017, we believe we were in compliance with all covenants set forth in the Second Amended Credit Agreement.

As of June 30, 2017, we had outstanding borrowings of approximately $235.5 million under the Second Amended Credit Agreement, with available borrowings of approximately $129.5 million, based on the leverage ratio required pursuant to the Second Amended Credit Agreement. Our interest rate as of June 30, 2017 was a fixed rate of 2.23% on $127.5 million and a fixed rate of 2.37% on $47.5 million as a result of interest rate swaps (see Note 10) and a variable floating rate of 2.48% on $60.5 million. Our interest

34

rate as of December 31, 2016 was a fixed rate of 2.98% on $130.0 million and 3.12% on $45.0 million as a result of interest rate swaps and a variable floating rate of 2.77% on approximately $150.0 million.

Cash flows used in investing activities.Our cash flow used in investing activities for the six-month period ended June 30, 2017 was approximately $73.7 million, compared to approximately $43.9 million for the six-month period ended June 30, 2016, an increase of approximately $29.7 million. This increase was primarily a result of increased cash paid for acquisitions during the six months ended June 30, 2017, compared to the six months ended June 30, 2016, principally the cash paid in the acquisitions of the Catheter Connections assets and the Argon critical care division (see Note 5 of the condensed notes to our consolidated financial statements). 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.

Capital expenditures for property and equipment were approximately $17.8 million and $21.2 million for the six-month periods ended June 30, 2017 and 2016, respectively.

We currently believe that our existing cash balances, anticipated future cash flows from operations, equipment financing 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; however, if we pursue and complete significant transactions or acquisitions in the future, additional funds may be required to facilitate such transactions.

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-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, 2016, 2015 and 2014, we recorded obsolescence expense of approximately $3.9 million, $2.8 million, and $2.3 million, respectively, and wrote off approximately $2.8 million, $2.5 million, and $2.4 million, respectively. Based on this historical trend, we believe that our inventory balances as of June 30, 2017 have been accurately adjusted for any unmarketable and/or slow-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. 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-

35

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 amount of tax positions that has 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 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. Such differences 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 Assets Impairment and Contingent Consideration. 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 2016, which was completed during the third quarter of 2016, 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 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. All our intangible assets are subject to amortization.

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 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 DISCLOSURES ABOUT MARKET RISK

Currency Risk.Our principal market risk relates to changes in the value of the Euro (EUR), Chinese Yuan Renminbi (CNY), and British Pound (GBP) relative to the value of the U.S. Dollar (USD). We also have a limited market risk relating to the 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 Dollar (SGD), Japanese Yen (JPY), and South Korean Won (KRW). Our consolidated financial statements are denominated in, and our principal currency is, the U.S. Dollar. For the three-month period ended June 30, 2017, a portion of our net sales (approximately $54.2 million, representing approximately 29.1% 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, will positively affect our net income. Excluding the effect of our hedging program, a strengthening U.S. Dollar against the Euro of 10% would increase our annual net income by approximately $2.6 million. Conversely, a weakening U.S. Dollar against the Euro of 10% would decrease our annual net income by approximately $2.6 million. A strengthening U.S. Dollar against the Chinese Yuan Renminbi of 10% would decrease our annual net income by approximately $5.3 million. Conversely, a weakening U.S. Dollar against the Chinese Yuan Renminbi of 10% would increase our annual net income by approximately $5.3 million dollars. During the three-month period ended June 30, 2017, using the foreign exchange rates in effect during the comparable prior-year period, exchange rate fluctuations of foreign currencies against the U.S. Dollar resulted in a decrease in our gross revenues of approximately $2.1 million, or 1.1%, and a decrease in gross margin of approximately $1.9 million, or 2.2% (or approximately 50 basis points in gross margin percentage), primarily as a result of unfavorable impacts to revenue due to sales denominated in EUR, CNY and GBP, partially offset by favorable impacts due to decreases in manufacturing costs from our facility in Tijuana, Mexico denominated in MXN and from our facility in Ireland denominated in EUR.

We forecast our net exposure in various receivables and payables to fluctuations in value of various currencies, and we enter into foreign currency forward contracts to mitigate that exposure. As of June 30, 2017, 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):

Currency	Symbol	Forward Notional Amount
Euro	EUR	22,779
British Pound	GBP	811
Chinese Yuan Renminbi	CNY	53,310
Mexican Peso	MXN	12,663
Brazilian Real	BRL	7,400
Australian Dollar	AUD	5,270
Hong Kong Dollar	HKD	11,000
Swiss Franc	CHF	215
Swedish Krona	SEK	3,552
Canadian Dollar	CAD	2,100
Singapore Dollar	SGD	4,902
Japanese Yen	JPY	120,000
South Korean Won	KRW	1,800,000

We also forecast our net exposure related to sales and expenses denominated in foreign currencies. As of June 30, 2017, 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):

37

Currency	Symbol	Forward Notional Amount
Euro	EUR	8,375
Swiss Franc	CHF	1,448
Danish Krone	DKK	9,955
British Pound	GBP	3,355
Mexican Peso	MXN	83,325
Swedish Krona	SEK	13,930

See Note 10 to our consolidated financial statements for a discussion of our foreign currency forward contracts.

Interest Rate Risk. As discussed in Note 10 to our consolidated financial statements, we had outstanding borrowings of approximately $235.5 million under the Second Amended Credit Agreement as of June 30, 2017. Accordingly, our earnings and after-tax cash flow are affected by changes in interest rates. As part of our efforts to mitigate interest rate risk, on December 19, 2012, we entered into a LIBOR-based interest rate swap agreement having an initial notional amount of $150.0 million with Wells Fargo to fix the one-month LIBOR rate at 0.98%. As of June 30, 2017, a notional amount of $127.5 million remained on the interest rate swap agreement, which expires on December 19, 2017. On August 5, 2016, we entered into a pay-fixed, receive-variable interest rate swap having an initial notional amount of $42.5 million with Wells Fargo to fix the one-month LIBOR rate at 1.12%. The notional amount of this interest rate swap increases quarterly by an amount equal to the decrease of the hedge entered into on December 19, 2012, up to the amount of $175 million. The interest rate swap is scheduled to expire on July 6, 2021. These instruments are intended to reduce our exposure to interest rate fluctuations and were 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 $605,000 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, 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 Securities Exchange Act of 1934, as amended (the "Exchange Act"), as of June 30, 2017. 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

Except as set forth below, during the quarter ended June 30, 2017, 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).

On January 31, 2017, we completed our acquisitions of the Catheter Connections assets and the critical care division of Argon. We are currently integrating the policies, processes, employees, technology and operations of the Catheter Connections assets and the critical care division of Argon. Management does not currently expect a material change to our internal controls over financial reporting as we fully integrate the Catheter Connections assets and the critical care division of Argon into our operations.

Management will continue to evaluate our internal control over financial reporting as we execute acquisition integration activities.

As of June 30, 2017, the total remaining unrecognized compensation cost related to non-vested stock options, net of expected forfeitures, was approximately $17.3 million and is expected to be recognized over a weighted average period of 3.87 years.

During the three and six-month periods ended June 30, 2017, we granted stock-based awards representing approximately 1.28 million shares of our common stock. During the three and six-month periods ended June 30, 2016, we granted stock-based awards representing 220,875 and 784,375 shares of our common stock, respectively. We use the Black-Scholes methodology to value the stock-based compensation expense for options. In applying the Black-Scholes methodology to the options granted during the six-month periods ended June 30, 2017 and 2016, the fair value of our stock-based awards granted was estimated using the following assumptions for the periods indicated below:

	Six months ended June 30,
	2017	2016
Risk-free interest rate	1.77% - 1.79%	1.25% - 1.40%
Expected option life	5.0 years	5.0 years
Expected dividend yield	—%	—%
Expected price volatility	33.81% - 34.03%	36.50% - 37.06%

For the purpose of the foregoing analysis, 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 option. 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 life 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.

Acquisitions

Business Combinations [Abstract]

Acquisitions

. On May 23, 2017, we paid $2.5 million to acquire 182,000 shares of preferred stock of Fusion Medical, Inc. ("Fusion"), a developer of medical devices designed for clot removal. The shares of preferred stock we acquired, which represent an ownership interest of approximately 19.5%, have been accounted for as an equity method investment of $2.5 million reflected within other assets in the accompanying consolidated balance sheets because we may be deemed to exercise significant influence over the operations of Fusion.

On May 19, 2017, we entered into a business purchase agreement with Sugan Co, Ltd. ("Sugan"), a Japanese medical device distributor. Pursuant to this agreement, we terminated our distributor agreement with Sugan and acquired the customer list Sugan used in the distribution of our products in Japan. The consideration attributed to the customer list was approximately $1.1 million payable on or before December 31, 2017. The customer list is recorded as an other intangible asset and the amount due to Sugan is recorded in accrued expenses within the accompanying consolidated balance sheets. We intend to amortize the customer list on an accelerated basis over five years.

On May 1, 2017, we entered into an asset purchase agreement with Lazarus Medical Technologies, LLC to acquire rights to the patented technology for the Repositionable Chest Tube^TM and related devices. As of June 30, 2017, we had paid $570,000 in connection with this agreement. We are obligated to pay an additional $750,000 if certain milestones set forth in the agreement are reached. We are also required to pay royalties equal to 6% of net sales throughout the term of the agreement. We accounted for this transaction as an asset purchase. We recorded the amount paid upon closing as a license agreement intangible asset, which we intend to amortize over 15 years.

On May 1, 2017, we entered into an agreement and plan of merger with Vascular Access Technologies, Inc. ("VAT"), pursuant to which we acquired the SAFECVAD™ device. We accounted for this acquisition as a business combination. The purchase price for the business was $5.0 million. We also recorded $4.9 million of contingent consideration related to royalties payable to VAT pursuant to the agreement. The following table summarizes the preliminary purchase price allocated to the net assets acquired and liabilities assumed (in thousands):

Net Assets Acquired
Intangibles
Developed technology	7,800
In-process technology	850
Goodwill	4,323
Deferred tax liabilities	(3,073		)
Total net assets acquired	$	9,900

We are amortizing the developed technology intangible asset over fifteen years. 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 VAT acquisition, which are included in selling, general and administrative expenses in the accompanying consolidated statements of income, were not material.

On January 31, 2017, we signed a purchase agreement with Argon Medical Devices, Inc. ("Argon") to acquire Argon’s critical care division, including a manufacturing facility in Singapore, the related commercial operations in Europe and Japan, and certain inventories and intellectual property rights within the United States. We made an initial payment of approximately $10.9 million and received a subsequent reduction to the purchase price of approximately $797,000 related to a working capital adjustment according to the terms of the purchase agreement. We accounted for the acquisition as a business combination.

Acquisition-related costs associated with the acquisition of the Argon critical care division during the three and six-month periods ended June 30, 2017, which are included in selling, general and administrative expenses in the accompanying consolidated statements of income, were approximately $1.3 million and $2.4 million, respectively. The results of operations related to this acquisition have been included in our cardiovascular segment since the acquisition date. During the three and six-month periods ended June 30, 2017, our net sales of Argon products were approximately $11.7 million and $19.0 million, respectively. It is not practical to separately report the earnings related to the Argon acquisition, as we cannot split out sales costs related solely to the products we acquired from Argon, principally because our sales representatives sell multiple products (including the products we acquired from Argon) in our cardiovascular business segment.

The assets and liabilities in the initial purchase price allocation for the Argon 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 preliminary purchase price allocated to the net tangible and intangible assets acquired and liabilities assumed (in thousands):

		Preliminary Allocation			Adjustments (2)			Revised Preliminary Allocation
	Assets Acquired
	Cash and cash equivalents	$	1,436		$	—		$	1,436
	Trade receivables	8,351			—			8,351
	Inventories	12,217			(546		)	11,671

	Total liabilities assumed	(8,390		)	228			(8,162		)
	Total net assets acquired	23,140			(1,466		)	21,674
	Gain on bargain purchase (1)	(12,243		)	669			(11,574		)
	Total purchase price	$	10,897		$	(797	)	$	10,100
(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 for the three and six-month periods ended June 30, 2017, and includes a negative adjustment of $669,000 in the three-month period ended June 30, 2017. We believe the reason for the provisional 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.
(2)	Amounts represent adjustments to the preliminary purchase price allocation first presented in our March 31, 2017 Form 10-Q resulting from our ongoing activities, including reassessment of the assets acquired and liabilities assumed, with respect to finalizing our purchase price allocation for this acquisition.

With respect to the Argon 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 currently 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.

Given the timing of this acquisition, which closed during the first quarter of 2017, as well as the complexity of the acquisition, the entire purchase price allocation disclosed herein (as well as the gain on bargain purchase) is considered provisional at this time and is subject to adjustment to reflect information obtained about factors and circumstances that existed as of the acquisition date that if known would have affected the measurement of the amounts recognized as of that date. We are currently reassessing whether we have fully identified all the assets acquired and the liabilities assumed, and the measurement period remains open.

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, which are included in selling, general and administrative expenses in the accompanying consolidated statements of income, 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-month periods ended June 30, 2017, our net sales of the products acquired from Catheter Connections were approximately $2.5 million and $4.3 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 preliminarily allocated as follows (in thousands):

		Preliminary Allocation			Adjustments (1)			Revised Preliminary Allocation
	Assets Acquired
	Trade receivables	$	952		$	7		$	959
	Inventories	2,244			(87		)	2,157
	Prepaid expenses and other current assets	181			—			181
	Property and equipment	1,472			—			1,472
	Intangibles
	Developed technology	22,900			(1,800		)	21,100
	Customer lists	100			600			700
	Trademarks	2,900			—			2,900
	Goodwill	7,612			1,280			8,892
	Total assets acquired	38,361			—			38,361
	Liabilities Assumed
	Trade payables	(338		)	—			(338		)
	Accrued expenses	(23		)	—			(23		)
	Total liabilities assumed	(361		)	—			(361		)
	Net assets acquired	$	38,000		$	—		$	38,000
(1)	Amounts represent adjustments to the preliminary purchase price first presented in our Quarterly Report on Form 10-Q for the Quarter Ended March 31, 2017, resulting from our ongoing activities with respect to finalizing our purchase price allocation for this acquisition. The larger adjustments primarily relate to the valuation of the acquired intangible assets.

We are amortizing the Catheter Connections developed technology asset over 12 years, the related trademarks over 10 years, and the associated customer list 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 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. In the three-month period ended December 31, 2016, we negotiated the final net working capital adjustment resulting in a reduction to the purchase price of approximately $1.1 million. As a result, we recorded measurement period adjustments to reduce inventories by approximately $89,000, reduce property and equipment by approximately $109,000, reduce goodwill by approximately $1.2 million, reduce accrued expenses by approximately $407,000 and increase the associated deferred tax liabilities by approximately $113,000. The measurement period for this acquisition is now closed. Under GAAP, measurement period adjustments are recognized on a prospective basis in the period of change, instead of restating prior periods. There was no material impact to reported earnings in connection with these measurement period adjustments.

Acquisition-related costs associated with the DFINE acquisition during the year ended December 31, 2016, which were included in selling, general and administrative expenses in the consolidated statements of income included in the 2016 Form 10-K, 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 year ended December 31, 2016, our net sales of DFINE products were approximately $13.5 million. It is not practical to separately report the earnings related to the DFINE acquisition, as we cannot split out sales costs related solely to the DFINE products, principally because our sales representatives sell 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):

Assets Acquired
Trade receivables	$	4,054
Other receivables	6
Inventories	8,585
Prepaid expenses	630
Property and equipment	1,630
Other long-term assets	145
Intangibles
Developed technology	67,600
Customer lists	2,400
Trademarks	4,400
Goodwill	24,818
Total assets acquired	114,268
Liabilities Assumed
Trade payables	(1,790		)
Accrued expenses	(5,298		)
Deferred income tax liabilities - current	(701		)
Deferred income tax liabilities - noncurrent	(10,844		)
Total liabilities assumed	(18,633		)
Net assets acquired, net of cash received of $1,327	$	95,635

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 equipment	290
Intangibles
Developed technology	12,100
Trademarks	700
Customers Lists	400
Goodwill	2,555
Total assets acquired	$	18,500

We are amortizing the developed HeRO Graft technology asset over ten 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 9.82 years. Acquisition-related costs related to the HeRO Graft device and other related assets during the year ended December 31, 2016, which were included in selling, general and administrative expenses in the consolidated statements of income included in the 2016 Form 10-K, were not material. The results of operations related to this acquisition have been included in our cardiovascular segment since the acquisition date. During the year ended December 31, 2016, our net sales of the products acquired from CryoLife were approximately $7.1 million. It is not practical to separately report the earnings related to the products acquired from CryoLife, as we cannot split out sales costs related solely to those products, principally because our sales representatives sell multiple products (including the HeRO Graft device) in the cardiovascular business segment.

* The pro forma results for the three-month period ended June 30, 2017 are not included in the table above because the operating results for the DFINE and Argon critical care division acquisitions were included in our consolidated statements of income for this period.

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, interest expense on long-term debt and changes in the timing of the recognition of the gain on bargain purchase. The pro forma information should not be considered indicative of actual results that would have been achieved if the DFINE acquisition had occurred on January 1, 2015 and the acquisition of the Argon critical care division had occurred on January 1, 2016, or results that may be obtained in any future period. The pro forma consolidated results of operations do not include the VAT, Catheter Connections or HeRO Graft acquisitions as we do not deem the pro forma effect of these transactions to be material.

Segment Reporting and Foreign Operations

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"), and interventional oncology and spine devices. Our endoscopy segment consists of gastroenterology and pulmonology medical device products which assist in the palliative treatment of expanding esophageal, tracheobronchial and biliary strictures caused by malignant tumors. We evaluate the performance of our operating segments based on operating income.

Accounting Changes and Error Corrections [Abstract]

Description of New Accounting Pronouncements Not yet Adopted

Financial Accounting Standards.

Recently Adopted

In January 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates the requirement to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under these amendments, goodwill impairment testing will be performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. We adopted ASU 2017-04 effective January 1, 2017 on a prospective basis, and it did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which provides guidance to entities to assist with evaluating when a set of transferred assets and activities is a business and provides a screen to determine when a set is not a business. Under the new guidance, when substantially all the fair value of gross assets acquired (or disposed of) is concentrated in a single identifiable asset, or group of similar assets, the assets acquired would not represent a business. Also, to be considered a business, an acquisition would have to include an input and a substantive process that together significantly contribute to the ability to produce outputs. We adopted ASU 2017-01 effective January 1, 2017 on a prospective basis. The implementation of ASU 2017-01 did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which requires companies to record excess tax benefits and deficiencies in income rather than the current requirement to record them through equity. ASU 2016-09 also allows companies the option to recognize forfeitures of share-based awards when they occur rather than the previous requirement to make an estimate upon the grant of the awards. We adopted ASU 2016-09 effective January 1, 2017 on a prospective basis and, as such, no prior periods were adjusted. In accordance with the new standard and prospectively since the date we adopted ASU 2016-09, excess tax benefits from stock-based compensation are reported as an income tax benefit in our consolidated statements of income (see Note 8).

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which requires all deferred tax assets and deferred tax liabilities to be presented as noncurrent within a classified balance sheet. We adopted ASU 2015-17 effective January 1, 2017 on a prospective basis and did not reclassify presentation of prior year balances. The adoption of this standard did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. ASU 2015-11 requires that inventory be measured at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Inventory measured using last-in, first-out or the retail inventory method are excluded from the scope of ASU 2015-11, which is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The implementation of ASU 2015-11 did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

Not Yet Adopted

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other than Inventory, which requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. ASU 2016-16 will be effective for us on January 1, 2018. We are currently evaluating the anticipated impact of adopting ASU 2016-16 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. ASU 2016-15 will be effective for us on January 1, 2018 with early adoption permitted. We do not presently anticipate that the adoption of ASU 2016-15 will have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases, 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.

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. ASU 2016-01 will be effective for us on January 1, 2018. Early adoption is not permitted except for the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income. Upon adoption of ASU 2016-01, an entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance is effective. We do not presently anticipate that the adoption of ASU 2016-01 will have a material impact on our financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), to update the financial reporting requirements for revenue recognition. Topic 606 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The guidance is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. This guidance is effective for us beginning on January 1, 2018, and entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. We have not yet reached a conclusion on whether we will adopt this new standard on a prospective or retrospective basis.

We are concluding the assessment phase of implementing this guidance. We have evaluated each of the five steps in Topic 606, which are as follows: 1) Identify the contract with the customer; 2) Identify the performance obligations in the contract; 3) Determine the transaction price; 4) Allocate the transaction price to the performance obligations; and 5) Recognize revenue when (or as) performance obligations are satisfied. Our preliminary conclusion is that we expect to identify similar performance obligations under ASC Topic 606 as compared with deliverables and separate units of account previously identified. As a result, we expect the timing of our revenue to remain largely the same in comparison to the current revenue recognition guidance. There are also certain considerations related to internal control over financial reporting that are associated with implementing Topic 606. We are currently evaluating our control framework for revenue recognition and identifying any changes that may need to be made in response to the new guidance. Disclosure requirements under the new guidance in Topic 606 have been significantly expanded in comparison to the disclosure requirements under the current guidance. Designing and implementing the appropriate controls over gathering and reporting the information required under Topic 606 is currently in process.

Income Tax Disclosure [Abstract]

Income Taxes

Income Taxes. Our overall effective tax rate for the three months ended June 30, 2017 and 2016 was 16.2% and 26.1%, respectively, which resulted in a provision for income taxes of approximately $1.8 million and $2.6 million, respectively. Our overall effective tax rate for the six months ended June 30, 2017 and 2016 was 9.4% and 26.2%, respectively, which resulted in a provision for income taxes of approximately $2.5 million and $4.1 million, respectively. A higher mix of earnings from our foreign operations, primarily in Ireland, which are taxed at lower rates than our U.S. operations and a discrete tax benefit related to share-based payment awards due to the application of ASU No. 2016-09 decreased our effective income tax rates for both periods, when compared to the prior year periods. A nontaxable gain on the bargain purchase relating to the acquisition of the critical care division of Argon also decreased the effective income tax rate for the six-month period ended June 30, 2017, when compared to the corresponding period of 2016.

2017 Debt Facility

On February 23, 2017, we entered into a 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 matures on February 1, 2018, with an extension available at our option, subject to certain conditions. The loan agreement bears interest at the three-month London Inter-Bank Offered Rate (“LIBOR”) plus 1.0%, which resets quarterly. The loan is secured by assets equal to the currently outstanding loan balance. The loan contains covenants, representations and warranties and other terms customary for loans of this nature. As of June 30, 2017, our interest rate on the loan was a variable rate of 2.12%.

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, 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 and on March 20, 2017 to allow flexibility in how we apply net proceeds received from equity issuances to prepay outstanding indebtedness.

The Second Amended Credit Agreement provides for a term loan of $150 million and a revolving credit commitment up to an aggregate amount of $275 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 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)
	As of June 30, 2017	4.0 to 1.0
	July 1, 2017 through December 31, 2017	3.75 to 1.0
	January 1, 2018 through March 31, 2018	3.5 to 1.0
	April 1, 2018 and thereafter	3.25 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, 2017, we believe we were in compliance with all covenants set forth in the Second Amended Credit Agreement.

As of June 30, 2017, we had outstanding borrowings of approximately $235.5 million under the Second Amended Credit Agreement, with available borrowings of approximately $129.5 million, based on the leverage ratio required pursuant to the Second Amended Credit Agreement. Our interest rate as of June 30, 2017 was a fixed rate of 2.23% on $127.5 million and a fixed rate of 2.37% on $47.5 million as a result of interest rate swaps (see Note 10), and a variable floating rate of 2.48% on $60.5 million. Our interest rate as of December 31, 2016 was a fixed rate of 2.98% on $130.0 million and 3.12% on $45.0 million as a result of interest rate swaps and a variable floating rate of 2.77% on approximately $150.0 million.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

Derivatives

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 programs 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. For the ineffective portions of qualifying hedges, the change in fair value is recorded through earnings in the period of change. 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.

Derivatives Designated as Cash Flow Hedges

On December 19, 2012, we entered into a pay-fixed, receive-variable interest rate swap having an initial notional amount of $150 million with Wells Fargo to fix the one-month LIBOR rate at 0.98%. The variable portion of the interest rate swap is tied to the one-month LIBOR rate (the benchmark interest rate). 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 on a monthly basis. The notional amount of the interest rate swap is reduced quarterly by 50% of the minimum principal payment due under the terms of our Second Amended Credit Agreement. The interest rate swap is scheduled to expire on December 19, 2017.

On August 5, 2016, we entered into a pay-fixed, receive-variable interest rate swap having an initial notional amount of $42.5 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 notional amount of the interest rate swap increases quarterly by an amount equal to the decrease of the hedge entered into on December 19, 2012, up to the amount of $175.0 million. The interest rate swap is scheduled to expire on July 6, 2021.

At June 30, 2017 and December 31, 2016, our interest rate swaps qualified as cash flow hedges. The fair value of our interest rate swaps at June 30, 2017 was an asset of approximately $4.5 million, which was partially offset by approximately $1.7 million in deferred taxes. The fair value of our interest rate swaps at December 31, 2016 was an asset of approximately $5.0 million, which was partially offset by approximately $1.9 million in deferred taxes.

Foreign Currency Risk. 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 Yuan Renminbi, Mexican Pesos, Brazilian Reals, Australian Dollars, Hong Kong Dollars, Swiss Francs, Swedish Krona, Canadian Dollars, Singapore Dollars, Japanese Yen, Korean Won, and Danish Krone. Our consolidated financial statements are denominated in, and our principal currency is, the U.S. Dollar. 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.

Derivatives 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 100 cash flow foreign currency hedges every month. As of June 30, 2017, 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):

Currency	Symbol	Forward Notional Amount
Euro	EUR	8,375
Swiss Franc	CHF	1,448
Danish Krone	DKK	9,955
British Pound	GBP	3,355
Mexican Peso	MXN	83,325
Swedish Krona	SEK	13,930

Derivatives 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, 2017, 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):

Currency	Symbol	Forward Notional Amount
Euro	EUR	22,779
British Pound	GBP	811
Chinese Yuan Renminbi	CNY	53,310
Mexican Peso	MXN	12,663

Balance Sheet Presentation of Derivatives. As of June 30, 2017 and December 31, 2016, all derivatives, both those designated as hedging instruments and those that were not designated as hedging instruments, were recorded gross at fair value on our consolidated balance sheets. We are not subject to any master netting agreements.

The net amount recognized in earnings during the three and six-month periods ended June 30, 2017 and 2016 due to ineffectiveness and amounts excluded from the assessment of hedge effectiveness were not significant.

As of June 30, 2017, approximately $483,000, or $295,000 after taxes, was expected to be reclassified from accumulated other comprehensive income to earnings in revenue and cost of sales over the succeeding twelve months. As of June 30, 2017, approximately $512,000, or $313,000 after taxes, was expected to be reclassified from accumulated other comprehensive income to earnings in interest expense over the succeeding twelve months.

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 each reporting period with the change in fair value recognized within operating expenses in the accompanying consolidated statements of income. 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. Changes in the fair value of our contingent consideration liability during the three and six-month periods ended June 30, 2017 and 2016, consisted of the following (in thousands):

	Three Months Ended June 30,						Six Months Ended June 30,
	2017			2016			2017			2016
Beginning balance	$	705		$	928		$	683		$	1,024
Contingent consideration liability recorded as the result of acquisitions (see Note 5)	4,900			—			4,900			—

Contingent payments made	(15		)	(16		)	(30		)	(183		)
Ending balance	$	5,572		$	898		$	5,572		$	898

The recurring Level 3 measurement of our contingent consideration liabilities and contingent receivable includes the following significant unobservable inputs at June 30, 2017 and December 31, 2016 (amounts in thousands):

Contingent consideration asset or liability	Fair value at June 30, 2017		Valuation technique	Unobservable inputs	Range
Revenue-based payments	$	5,572	Discounted cash flow	Discount rate	9.9% - 15%
contingent liability				Probability of milestone payment	100%
				Projected year of payments	2017-2033
Contingent receivable	$	528	Discounted cash flow	Discount rate	10%
asset				Probability of milestone payment	57%
				Projected year of payments	2017-2019
Contingent consideration asset or liability	Fair value at December 31, 2016		Valuation technique	Unobservable inputs	Range
Revenue-based payments	$	683	Discounted cash flow	Discount rate	9.9% - 15%
contingent liability				Probability of milestone payment	100%
				Projected year of payments	2017-2028
Contingent receivable	$	528	Discounted cash flow	Discount rate	10%
asset				Probability of milestone payment	57%
				Projected year of payments	2017-2019

The contingent consideration liabilities 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 liabilities and contingent receivable could change in future periods based upon our ongoing evaluation of these significant unobservable inputs. We record any such change in fair value to operating expenses in our consolidated statements of income. As of June 30, 2017, approximately $5.5 million was included in other long-term obligations and $69,000 was included in accrued expenses in our consolidated balance sheet. As of December 31, 2016, approximately $595,000 was included in other long-term obligations and $88,000 was included in accrued expenses in our consolidated balance sheet. The cash 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 three and six-month periods ended June 30, 2017, we had losses of approximately $1,000, and $19,000, respectively, compared to losses of approximately $90,000 and $90,000 for the three and six-month periods ended June 30, 2016, respectively, related to the measurement of non-financial assets at fair value on a nonrecurring basis subsequent to their initial recognition.

The carrying amount of cash and cash equivalents, trade receivables, and trade payables approximate fair value because of the immediate, short-term maturity of these financial instruments. The carrying amount of long-term debt approximates fair value, as determined by borrowing rates estimated to be available to us for debt with similar terms and conditions. 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.

Commitments and Contingencies Disclosure [Abstract]

Commitments and Contingencies

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, contractual, and employment matters. We do not believe that any such actions are likely to be, individually or in the aggregate, material to our business, financial condition, results of operations or liquidity. However, in the event of unexpected further developments, it is possible that the ultimate resolution of these matters, or other similar matters, if unfavorable, 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.

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 2017. We have incurred, and anticipate that we will continue to incur, substantial costs in connection with the matter. We incurred approximately $3.7 million and $8.5 million of expenses for the three and six-month periods ended June 30, 2017, respectively, responding to the pending subpoena from the U.S. Department of Justice. We expect that these expenses will be in a similar range in subsequent periods and may potentially be higher, depending on the progress of the investigation and other factors beyond our control. 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.

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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Principles of Consolidation

The interim consolidated financial statements of Merit Medical Systems, Inc. ("Merit," "we" or "us") for the three and six-month periods ended June 30, 2017 and 2016 are not audited. Our consolidated financial statements are prepared in accordance with the requirements for unaudited interim periods and, consequently, do not include all disclosures required to be made in conformity with accounting principles generally accepted in the United States of America. In the opinion of our management, the accompanying consolidated financial statements contain all adjustments, consisting of normal recurring accruals, necessary for a fair presentation of our financial position as of June 30, 2017 and December 31, 2016, and our results of operations and cash flows for the three and six-month periods ended June 30, 2017 and 2016. The results of operations for the three and six-month periods ended June 30, 2017 and 2016 are not necessarily indicative of the results for a full-year period. These interim consolidated financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K (the "2016 Form 10-K") for the year ended December 31, 2016, which was filed with the Securities and Exchange Commission (the "SEC") on March 1, 2017.

New Accounting Pronouncements

Financial Accounting Standards.

Recently Adopted

In January 2017, the Financial Accounting Standards Board (the “FASB”) issued Accounting Standards Update (“ASU”) No. 2017-04, Intangibles - Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment, which eliminates the requirement to determine the fair value of individual assets and liabilities of a reporting unit to measure goodwill impairment. Under these amendments, goodwill impairment testing will be performed by comparing the fair value of the reporting unit with its carrying amount and recognizing an impairment charge for the amount by which the carrying amount exceeds the reporting unit’s fair value. We adopted ASU 2017-04 effective January 1, 2017 on a prospective basis, and it did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

In January 2017, the FASB issued ASU No. 2017-01, Business Combinations (Topic 805): Clarifying the Definition of a Business, which provides guidance to entities to assist with evaluating when a set of transferred assets and activities is a business and provides a screen to determine when a set is not a business. Under the new guidance, when substantially all the fair value of gross assets acquired (or disposed of) is concentrated in a single identifiable asset, or group of similar assets, the assets acquired would not represent a business. Also, to be considered a business, an acquisition would have to include an input and a substantive process that together significantly contribute to the ability to produce outputs. We adopted ASU 2017-01 effective January 1, 2017 on a prospective basis. The implementation of ASU 2017-01 did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

In March 2016, the FASB issued ASU No. 2016-09, Compensation - Stock Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting, which requires companies to record excess tax benefits and deficiencies in income rather than the current requirement to record them through equity. ASU 2016-09 also allows companies the option to recognize forfeitures of share-based awards when they occur rather than the previous requirement to make an estimate upon the grant of the awards. We adopted ASU 2016-09 effective January 1, 2017 on a prospective basis and, as such, no prior periods were adjusted. In accordance with the new standard and prospectively since the date we adopted ASU 2016-09, excess tax benefits from stock-based compensation are reported as an income tax benefit in our consolidated statements of income (see Note 8).

In November 2015, the FASB issued ASU No. 2015-17, Income Taxes (Topic 740): Balance Sheet Classification of Deferred Taxes, which requires all deferred tax assets and deferred tax liabilities to be presented as noncurrent within a classified balance sheet. We adopted ASU 2015-17 effective January 1, 2017 on a prospective basis and did not reclassify presentation of prior year balances. The adoption of this standard did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

In July 2015, the FASB issued ASU No. 2015-11, Simplifying the Measurement of Inventory. ASU 2015-11 requires that inventory be measured at the lower of cost or net realizable value. Net realizable value is the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal, and transportation. Inventory measured using last-in, first-out or the retail inventory method are excluded from the scope of ASU 2015-11, which is effective for fiscal years beginning after December 15, 2016, and interim periods within those fiscal years. The implementation of ASU 2015-11 did not have a material impact on our consolidated financial statements for the six months ended June 30, 2017.

Not Yet Adopted

In October 2016, the FASB issued ASU No. 2016-16, Income Taxes (Topic 740): Intra-Entity Transfers of Assets Other than Inventory, which requires the recognition of the income tax consequences of an intra-entity transfer of an asset, other than inventory, when the transfer occurs. ASU 2016-16 will be effective for us on January 1, 2018. We are currently evaluating the anticipated impact of adopting ASU 2016-16 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. ASU 2016-15 will be effective for us on January 1, 2018 with early adoption permitted. We do not presently anticipate that the adoption of ASU 2016-15 will have a material impact on our consolidated financial statements.

In February 2016, the FASB issued ASU No. 2016-02, Leases, 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.

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. ASU 2016-01 will be effective for us on January 1, 2018. Early adoption is not permitted except for the provision to record fair value changes for financial liabilities under the fair value option resulting from instrument-specific credit risk in other comprehensive income. Upon adoption of ASU 2016-01, an entity should apply the amendments by means of a cumulative-effect adjustment to the balance sheet at the beginning of the first reporting period in which the guidance is effective. We do not presently anticipate that the adoption of ASU 2016-01 will have a material impact on our financial statements.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (Topic 606), to update the financial reporting requirements for revenue recognition. Topic 606 outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The guidance is based on the principle that an entity should recognize revenue to depict the transfer of goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. The guidance also requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments and assets recognized from costs incurred to fulfill a contract. This guidance is effective for us beginning on January 1, 2018, and entities have the option of using either a full retrospective or a modified retrospective approach for the adoption of the new standard. We have not yet reached a conclusion on whether we will adopt this new standard on a prospective or retrospective basis.

We are concluding the assessment phase of implementing this guidance. We have evaluated each of the five steps in Topic 606, which are as follows: 1) Identify the contract with the customer; 2) Identify the performance obligations in the contract; 3) Determine the transaction price; 4) Allocate the transaction price to the performance obligations; and 5) Recognize revenue when (or as) performance obligations are satisfied. Our preliminary conclusion is that we expect to identify similar performance obligations under ASC Topic 606 as compared with deliverables and separate units of account previously identified. As a result, we expect the timing of our revenue to remain largely the same in comparison to the current revenue recognition guidance. There are also certain considerations related to internal control over financial reporting that are associated with implementing Topic 606. We are currently evaluating our control framework for revenue recognition and identifying any changes that may need to be made in response to the new guidance. Disclosure requirements under the new guidance in Topic 606 have been significantly expanded in comparison to the disclosure requirements under the current guidance. Designing and implementing the appropriate controls over gathering and reporting the information required under Topic 606 is currently in process.

Derivatives

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 programs 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. For the ineffective portions of qualifying hedges, the change in fair value is recorded through earnings in the period of change. 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.

Derivatives Designated as Cash Flow Hedges

On December 19, 2012, we entered into a pay-fixed, receive-variable interest rate swap having an initial notional amount of $150 million with Wells Fargo to fix the one-month LIBOR rate at 0.98%. The variable portion of the interest rate swap is tied to the one-month LIBOR rate (the benchmark interest rate). 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 on a monthly basis. The notional amount of the interest rate swap is reduced quarterly by 50% of the minimum principal payment due under the terms of our Second Amended Credit Agreement. The interest rate swap is scheduled to expire on December 19, 2017.

On August 5, 2016, we entered into a pay-fixed, receive-variable interest rate swap having an initial notional amount of $42.5 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 notional amount of the interest rate swap increases quarterly by an amount equal to the decrease of the hedge entered into on December 19, 2012, up to the amount of $175.0 million. The interest rate swap is scheduled to expire on July 6, 2021.

At June 30, 2017 and December 31, 2016, our interest rate swaps qualified as cash flow hedges. The fair value of our interest rate swaps at June 30, 2017 was an asset of approximately $4.5 million, which was partially offset by approximately $1.7 million in deferred taxes. The fair value of our interest rate swaps at December 31, 2016 was an asset of approximately $5.0 million, which was partially offset by approximately $1.9 million in deferred taxes.

Foreign Currency Risk. 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 Yuan Renminbi, Mexican Pesos, Brazilian Reals, Australian Dollars, Hong Kong Dollars, Swiss Francs, Swedish Krona, Canadian Dollars, Singapore Dollars, Japanese Yen, Korean Won, and Danish Krone. Our consolidated financial statements are denominated in, and our principal currency is, the U.S. Dollar. 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.

Derivatives 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.

	Total purchase price	$	10,897		$	(797	)	$	10,100
(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 for the three and six-month periods ended June 30, 2017, and includes a negative adjustment of $669,000 in the three-month period ended June 30, 2017. We believe the reason for the provisional 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.
(2)	Amounts represent adjustments to the preliminary purchase price allocation first presented in our March 31, 2017 Form 10-Q resulting from our ongoing activities, including reassessment of the assets acquired and liabilities assumed, with respect to finalizing our purchase price allocation for this acquisition.
