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-month periods ended March 31, 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 March 31, 2017 and December 31, 2016, and our results of operations and cash flows for the three-month periods ended March 31, 2017 and 2016. The results of operations for the three-month periods ended March 31, 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 March 31, 2017 and December 31, 2016 consisted of the following (in thousands):

| March 31, |  | December 31,
| 2017 |  | 2016
Finished goods | $ | 69,130 |  |  | $ | 63,852 |
Work-in-process | 15,724 |  |  | 11,008 |
Raw materials | 49,456 |  |  | 45,835 |
Total | $ | 134,310 |  |  | $ | 120,695 |

3. Stock-Based Compensation. Stock-based compensation expense before income tax expense for the three-month periods ended March 31, 2017 and 2016, consisted of the following (in thousands):

| Three Months Ended March 31,
| 2017 |  | 2016
Cost of goods sold | $ | 96 |  |  | $ | 123 |
Research and development | 52 |  |  | 42 |
Selling, general, and administrative | 429 |  |  | 459 |
Stock-based compensation expense before taxes | $ | 577 |  |  | $ | 624 |

As of March 31, 2017, the total remaining unrecognized compensation cost related to non-vested stock options, net of expected forfeitures, was approximately $7.2 million and is expected to be recognized over a weighted average period of 3.19 years.
During the three-month period ended March 31, 2017, we did not grant any new stock-based awards. During the three-month period ended March 31, 2016, we granted stock-based awards representing 563,500 shares of our common stock. We use the Black-Scholes methodology to value the stock-based compensation expense for options. In applying the Black-Scholes methodology to the options granted during the three-month period ended March 31, 2016, the fair value of our stock-based awards granted was estimated using the following assumptions for the periods indicated below:

|  | Three months ended
|  | March 31, 2016
Risk-free interest rate |  | 1.4%
Expected option life |  | 5.0 years
Expected dividend yield |  | —%
Expected price volatility |  | 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

Table of Contents
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):

| Net Income |  | Shares |  | Per Share Amount
Three-month period ended March 31, 2017: |  |  |  |  |  |  |  |
Basic EPS | $ | 14,803 |  |  | 44,830 |  |  | $ | 0.33 |
Effect of dilutive stock options and warrants |  |  |  | 990 |  |  |  |
Diluted EPS | $ | 14,803 |  |  | 45,820 |  |  | $ | 0.32 |
Stock options excluded from the calculation of common stock equivalents as the impact was anti-dilutive |  |  | 96 |  |  |
Three-month period ended March 31, 2016: |  |  |  |  |  |  |  |
Basic EPS | $ | 4,351 |  |  | 44,275 |  |  | $ | 0.10 |
Effect of dilutive stock options and warrants |  |  |  | 304 |  |  |  |
Diluted EPS | $ | 4,351 |  |  | 44,579 |  |  | $ | 0.10 |
Stock options excluded from the calculation of common stock equivalents as the impact was anti-dilutive |  |  | 978 |  |  |

5. Acquisitions. On January 31, 2017, we signed a purchase agreement with Argon Medical Devices, Inc. ("Argon") to acquire Argon’s critical care business including a manufacturing facility in Yishun, 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 which is subject to a working capital adjustment. We accounted for the acquisition as a business combination.
Acquisition-related costs associated with the Argon acquisition during the three-month period ended March 31, 2017, which are included in selling, general, and administrative expenses in the accompanying consolidated statements of income, were approximately $1.1 million. The results of operations related to this acquisition have been included in our cardiovascular segment since the acquisition date. During the three-month period ended March 31, 2017, our net sales of Argon products were approximately $7.2 million. 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 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):

Assets Acquired |
Cash and cash equivalents | $ | 1,436 |
Trade receivables | 8,351 |
Inventories | 12,217 |
Prepaid expenses | 1,275 |
Property and equipment | 2,667 |
Deferred tax assets | 184 |
Intangibles |
Developed technology | 2,600 |
Customer lists | 1,300 |
Trademarks | 1,500 |
Total assets acquired | 31,530 |
Liabilities Assumed |
Trade payables | (2,306 | )
Accrued expenses | (5,083 | )
Income taxes payable | (2 | )
Deferred income tax liabilities | (999 | )
Total liabilities assumed | (8,390 | )
Total net assets acquired | 23,140 |
Gain on bargain purchase | (12,243 | )
Total purchase price | $ | 10,897 |

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.
The total fair value of the net assets acquired from Argon, including identifiable intangible assets, 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-month period ended March 31, 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. Given the circumstances of this acquisition, which closed during the first quarter, as well as the complexity of the transaction, the entire purchase price allocation disclosed herein (as well as the gain
11

Table of Contents
on bargain purchase) is considered provisional at this time and 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 correctly 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 million, which is subject to a working capital adjustment. Catheter Connections, which is 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-month period ended March 31, 2017, our net sales of the products acquired from Catheter Connections were approximately $1.8 million. 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):

Assets Acquired |
Trade receivables | $ | 952 |
Inventories | 2,244 |
Prepaid expenses and other current assets | 181 |

We are amortizing the 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 11.8 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 ("VCF") 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. Under GAAP, measurement period adjustments are recognized on a prospective basis in the period of change, instead of restating prior periods. There was no 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):

The gross amount of trade receivables we acquired in the DFINE acquisition was approximately $4.3 million, of which approximately $224,000 was expected to be uncollectible or returned. With respect to the DFINE assets, we are amortizing developed technology over fifteen 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 fifteen 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):

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 periods ended March 31, 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 business had occurred on January 1, 2016 (in thousands, except per share amounts):

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 business 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 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-month periods ended March 31, 2017, and 2016, are as follows (in thousands):

7. Recently Issued Financial Accounting Standards. 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 three months ended March 31, 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 2017-04 effective January 1, 2017 on a prospective basis. The implementation of ASU 2017-04 did not have a material impact on our consolidated financial statements for the three months ended March 31, 2017.
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 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 current requirement to make an estimate upon the grant of the awards. We adopted ASU 2016-09 effective January 1, 2017 on a prospective basis. The implementation of ASU 2016-09 did not have a material impact on our consolidated financial statements for the three months ended March 31, 2017.
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 November 2015, the FASB issued ASU 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 three months ended March 31, 2017.
In July 2015, the FASB issued ASU 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 three months ended March 31, 2017.
In May 2014, the FASB issued ASU 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 final 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 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 March 31, 2017 and 2016 was 4.5% and 26.3%, respectively, which resulted in a provision for income taxes of approximately $690,000 and $1.6 million, respectively. The decrease in the effective income tax rate for the first quarter of 2017, when compared to the first quarter of 2016, was due primarily to the nontaxable gain on the bargain purchase recorded in connection with the acquisition of the critical care division of Argon.

2017 Debt Facility
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 the Company's 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. Our interest rate as of March 31, 2017 was a variable rate of 2.06%.
2016 Term Loan and Revolving Credit Loans
On July 6, 2016, we entered into a Second Amended and Restated Credit Agreement (as amended to date, the “Second Amended Credit Agreement”), with Wells Fargo Bank, National Association, as administrative agent, swingline lender and a lender, and Wells Fargo Securities, LLC, as sole lead arranger and sole bookrunner. In addition to Wells Fargo Bank, National Association, Bank of America, N.A., U.S. Bank, National Association, and HSBC Bank USA, National Association, are parties to the Second Amended Credit Agreement as lenders. The Second Amended Credit Agreement amends and restates in its entirety Merit’s 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:

| 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 March 31, 2017, we believe we were in compliance with all covenants set forth in the Second Amended Credit Agreement.
As of March 31, 2017, we had outstanding borrowings of approximately $231.0 million under the Second Amended Credit Agreement, with available borrowings of approximately $136.5 million, based on the leverage ratio required pursuant to the Second Amended Credit Agreement. Our interest rate as of March 31, 2017 was a fixed rate of 3.12% on $46.3 million and a fixed rate of 2.98% on $128.8 million as a result of interest rate swaps (see Note 10), and a variable floating rate of 2.98% on $56.0 million. Our interest rate as of December 31, 2016 was a fixed rate of 3.12% on $45.0 million and 2.98% on $130.0 million as a result of interest rate swaps and a variable floating rate of 2.77% on approximately $150.0 million.

10. 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.
18

Table of Contents
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 March 31, 2017 and 2016, our interest rate swaps qualified as cash flow hedges. The fair value of our interest rate swaps at March 31, 2017 was an asset of approximately $5.4 million, which was partially offset by approximately $2.1 million in deferred taxes. The fair value of our interest rate swap at December 31, 2016 was an asset of approximately $5.0 million, which was 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.

(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) or 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 at 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-month periods ended March 31, 2017 and 2016, consisted of the following (in thousands):

| Three Months Ended March 31,
| 2017 |  | 2016
Beginning balance | $ | 683 |  |  | $ | 1,024 |
Fair value adjustments recorded to income during the period | 37 |  |  | 71 |

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

Contingent consideration asset or liability |  | Fair value at March 31, 2017 |  | Valuation technique |  | Unobservable inputs |  | Range
Revenue-based payments |  | $ | 705 |  |  | 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
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 March 31, 2017, approximately $609,000 was included in other long-term obligations and $96,000 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-month periods ended March 31, 2017 and 2016, we had losses of approximately $18,000, and $0, 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, 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 three-month period ended March 31, 2017 were as follows (in thousands):

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 $4.8 million and $1.0 million in expenses in the three-month periods ended March 31, 2017 and December 31, 2016, respectively, responding to the inquiry from the U.S. Department of Justice. We expect that these expenses will be in a similar range in subsequent quarters 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 $136.5 million, which is net of approximately $8.8 million in underwriting discounts and commissions and approximately $833,000 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 operation 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 March 31, 2017, we reported sales of approximately $171.1 million, up approximately $33.0 million or 23.9%, over sales from the three-month period ended March 31, 2016 of approximately $138.1 million.
Gross profit as a percentage of sales increased to 44.4% for the three-month period ended March 31, 2017 as compared to 43.5% for the three-month period ended March 31, 2016.
Net income for the three-month period ended March 31, 2017 was approximately $14.8 million, or $0.32 per share, as compared to $4.4 million, or $0.10 per share, for the three-month period ended March 31, 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.”

Sales for the three-month period ended March 31, 2017 were favorably affected by increased sales of our stand-alone devices (particularly our infusion bag, Map™, and Ensnare® products, as well as new sales from our acquisitions of the Hero Graft device, DFINE, Argon and Catheter Connections product lines) of approximately $20.8 million, up 47.9% and catheters (particularly our Impress® product line, Performa® vessel-sizing catheters, and our Maestro® microcatheters) of approximately $5.9 million, up 24.5%.
Our endoscopy sales for the three-month period ended March 31, 2017 were approximately $6.3 million, up 13.5%, when compared to sales in the corresponding period of 2016 of approximately $5.5 million. This increase 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 44.4% for the first quarter of 2017, compared to 43.5% for the first quarter of 2016 primarily due to changes in product mix and increased efficiencies gained from our operations group.
Operating Expenses. Selling, general, and administrative ("SG&A") expenses increased approximately $16.1 million, or 38.5%, for the three-month period ended March 31, 2017, compared to the three months ended March 31, 2016. As a percentage of sales, selling, general, and administrative expenses increased to 33.8% of sales for the three-month period ended March 31, 2017, compared to 30.2% of sales for the three-month period ended March 31, 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 Catheter Connections, legal expenses of approximately $4.8 million incurred in responding to the pending subpoena from the 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 March 31, 2017 were approximately $12.5 million, up 18.3%, when compared to research and development expenses in the corresponding period of 2016 of approximately $10.6 million. This increase was largely due to hiring of 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-month periods ended March 31, 2017 and 2016 (in thousands):

| Three Months Ended March 31,
| 2017 |  | 2016
Operating Income |  |  |  |
Cardiovascular | $ | 4,004 |  |  | $ | 6,648 |
Endoscopy | 1,605 |  |  | 1,058 |
Total operating income | $ | 5,609 |  |  | $ | 7,706 |

Cardiovascular Operating Income. Our cardiovascular operating income for the three-month period ended March 31, 2017 was approximately $4.0 million, compared to operating income of approximately $6.6 million for the three-month period ended March 31, 2016. This decrease was primarily related to headcount additions, $4.8 million of expenses incurred in responding to an inquiry 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 March 31, 2017 was approximately $1.6 million, compared to approximately $1.1 million for the three-month period ended March 31, 2016. This increase was primarily the result of higher sales and lower SG&A and research and development expenses as a percentage of sales, partially offset by a decrease in gross profit as a percentage of sales.
Income Taxes. Our effective income tax rate for the three-month period ended March 31, 2017 and 2016 was 4.5% and 26.3%, respectively. The decrease in the effective income tax rate for the first quarter of 2017, when compared to the first quarter of 2016, was due primarily to the nontaxable gain on the bargain purchase recorded in connection with the acquisition of the critical care division of Argon.
Other Income (Expense) - Net. Our other income (expense) for the three-month period ended March 31, 2017 and 2016 was income of approximately $9.9 million and expense of approximately $(1.8) million, respectively. The change in other income(expense) was principally the result of the gain on bargain purchase related to the acquisition of the Argon critical care division of approximately $12.2 million.
Net Income. Our net income for the three-month period ended March 31, 2017 and 2016 was approximately $14.8 million and $4.4 million, respectively. The increase in net income was primarily due to the gain on bargain purchase of $12.2 million related to the acquisition of the Argon critical care division, which was partially offset by $4.8 million of legal expenses incurred in responding to an inquiry 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 March 31, 2017 and December 31, 2016, we had cash and cash equivalents of approximately $26.5 million and $19.2 million respectively, of which $25.6 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 March 31, 2017 and December 31, 2016, we had cash and cash equivalents of approximately $15.5 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 three-month periods ended March 31, 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 March 31, 2017 and December 31, 2016 was approximately $167.1 million and $155.1 million, respectively. The increase in working capital as of March 31, 2017 compared to December 31, 2016 was primarily the result of increases in cash, trade receivables and inventories, which were partially offset by an increase in trade payables, accrued expenses and the current portion of long-term debt. As of March 31, 2017 and December 31, 2016, we had a current ratio of 2.59 to 1 and 2.76 to 1, respectively.
During the three-month period ended March 31, 2017, our inventory balance increased approximately $13.6 million, from approximately $120.7 million as of December 31, 2016 to approximately $134.3 million as of March 31, 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 March 31, 2017 decreased to 2.91, compared to 3.10 as of March 31, 2016.
Cash flows provided by financing activities. Cash provided by financing activities for the three-month period ended March 31, 2017 was approximately $50.7 million, compared to cash provided by financing actives of approximately $21.2 million for the three-month period ended March 31, 2016, a change of approximately $29.5 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 in which we received proceeds of approximately $136.5 million, which is net of approximately $8.8 million in underwriting discounts and commissions and approximately $833,000 in other direct costs incurred and paid by us in connection with this equity 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 the Company's 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. Our interest rate as of March 31, 2017 was a variable rate of 2.06%.
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:

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 March 31, 2017, we believe we were in compliance with all covenants set forth in the Second Amended Credit Agreement.
As of March 31, 2017, we had outstanding borrowings of approximately $231.0 million under the Second Amended Credit Agreement, with available borrowings of approximately $136.5 million, based on the leverage ratio required pursuant to the Second Amended Credit Agreement. Our interest rate as of March 31, 2017 was a fixed rate of 3.12% on $46.3 million and 2.98% on $128.8 million as a result of interest rate swaps (see Note 10) and a variable floating rate of 2.98% on $56.0 million. Our interest rate as of December 31, 2016 was a fixed rate of 3.12% on $45.0 million and 2.98% on $130.0 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 three-month period ended March 31, 2017 was approximately $58.3 million, compared to approximately $31.9 million for the three-month period ended March 31, 2016, an increase of approximately $26.4 million. This increase was primarily a result of increased cash paid for acquisitions during the quarter ended March 31, 2017, compared to the quarter ended March 31, 2016, principally the cash paid in the acquisitions of Catheter Connections and Argon (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 $10.2 million and $11.0 million for the three-month periods ended March 31, 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
33

Table of Contents
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 March 31, 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-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,
34

Table of Contents
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 DISCLOSURE 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), and Danish Krone (DKK). Our consolidated financial statements are denominated in, and our principal currency is, the U.S. Dollar. For the three-month period ended March 31, 2017, a portion of our net sales (approximately $48.1 million, representing approximately 28.1% 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 $2.4 million. Conversely, a weakening U.S. Dollar against the Euro of 10% would decrease our annual net income by approximately $2.4 million. A strengthening U.S. Dollar against the Chinese Yuan Renminbi of 10% would decrease our annual net income by approximately $5.0 million. Conversely, a weakening U.S. Dollar against the Chinese Yuan Renminbi of 10% would increase our annual net income by approximately $5.0 million dollars. During the three-month period ended March 31, 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 $1.3 million, or 0.73%, and a decrease in gross margin of approximately $487,000, or 0.64% (or approximately 4 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 March 31, 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 | 23,215 |
British Pound | GBP | 824 |
Chinese Yuan Renminbi | CNY | 40,300 |
Mexican Peso | MXN | 14,374 |
Brazilian Real | BRL | 3,700 |
Australian Dollar | AUD | 4,742 |
Hong Kong Dollar | HKD | 11,000 |
Swiss Franc | CHF | 240 |
Swedish Krona | SEK | 3,561 |
Canadian Dollar | CAD | 1,320 |
Singapore Dollar | SGD | 3,900 |
Japanese Yen | JPY | 106,000 |
South Korean Won | KRW | 1,500,000 |

We also forecast our net exposure related to sales and expenses denominated in foreign currencies. As of March 31, 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):
36

Table of Contents

Currency | Symbol | Forward Notional Amount |
Euro | EUR | 9,635 |
Swiss Franc | CHF | 1,568 |
Danish Krone | DKK | 9,895 |
British Pound | GBP | 3,600 |
Mexican Peso | MXN | 88,825 |
Swedish Krona | SEK | 15,100 |

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 $231 million under the Second Amended Credit Agreement as of March 31, 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 March 31, 2017, a notional amount of $46.3 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 $560,000 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 March 31, 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 March 31, 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 acquisition of Catheter Connections and the critical care business of Argon. We are currently integrating the policies, processes, employees, technology and operations of Catheter Connections and the critical care business of Argon. Management does not currently expect a material change to our internal controls over financial reporting as we fully integrate Catheter Connections and the critical care business of Argon into our operations.
Management will continue to evaluate our internal control over financial reporting as we execute acquisition integration activities.
