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 months ended March 31, 2020 and 2019 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, 2020 and December 31, 2019, and our results of operations and cash flows for the three-month periods ended March 31, 2020 and 2019. The results of operations for the three-month periods ended March 31, 2020 and 2019 are not necessarily indicative of the results for a full-year period. Within the financial statements and tables presented, certain columns and rows may not total due to the use of rounded numbers for disclosure purposes. Percentages and earnings per share amounts presented are calculated from the underlying amounts. These interim consolidated financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K (the "2019 Form 10-K") for the year ended December 31, 2019, which was filed with the Securities and Exchange Commission (the "SEC") on March 2, 2020.

Reclassifications

Certain reclassifications have been made to the 2019 periods to conform to the 2020 presentation. In the consolidated statements of cash flows, the fair value adjustment to contingent consideration is presented as a reconciling item between net income (loss) and cash flows from operating activities in 2020, with a corresponding reclassification of $775,000 made in the prior period for comparability, along with corresponding reclassifications to the change in certain operating assets and liabilities.

2.   Recently Issued Financial Accounting Standards.

Recently Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 became effective for us on January 1, 2020. The adoption of this standard did not have a material impact on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), which removes, modifies and adds various disclosure requirements related to fair value disclosures. ASU 2018-13 became effective for us beginning on January 1, 2020. We modified our disclosures beginning in the three-month period ended March 31, 2020 to conform with this guidance (see Note 14).

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaced the incurred loss impairment methodology for financial assets with a methodology that reflects expected credit losses. The new credit loss model must be applied to loans, accounts receivable, and other financial assets. ASU 2016-13 became effective for us beginning on January 1, 2020. We adopted this standard using a modified retrospective approach with a cumulative-effect adjustment to retained earnings of $575,000 as of the beginning of 2020. See Note 14 for additional disclosures related to our allowance for current expected credit losses. The adoption of this guidance did not have a material impact on our statements of operations or cash flows.

We currently believe that all other issued and not yet effective accounting standards are not relevant to our financial statements.

3.   Revenue from Contracts with Customers. We recognize revenue when a customer obtains control of promised goods. The amount of revenue recognized reflects the consideration we expect to receive in exchange for these goods.

Disaggregation of Revenue

The disaggregation of revenue is based on product category and geographical region. Beginning in the first quarter of 2020, we revised our product categories to more clearly reflect how we sell our products to our customers. We presented historical information under the new revised product categories in a Current Report on Form 8-K, filed with the SEC on April 3, 2020.

We design, develop, manufacture and market 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 four product categories: peripheral intervention, cardiac intervention, custom procedural solutions, and OEM. Within these product categories, we sell a variety of products, including cardiology and radiology devices (which assist in diagnosing and treating coronary arterial disease, peripheral vascular disease and other non-vascular diseases), as well as embolotherapeutic, cardiac rhythm management, electrophysiology, critical care, breast cancer localization and guidance, biopsy, 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.

The following tables present revenue from contracts with customers for the three-month periods ended March 31, 2020 and 2019 (in thousands):

4.   Acquisitions. On August 1, 2019, we entered into a share purchase agreement to acquire Fibrovein Holdings Limited, which is the owner of 100% of the capital stock of STD Pharmaceutical Products Limited, a UK private company engaged in the manufacture, distribution and sale of pharmaceutical sclerotherapy products (“STD Pharmaceutical”). The purchase consideration consisted of an upfront payment of approximately $13.7 million, net of cash acquired. We also recorded a contingent consideration liability of approximately $934,000 related to royalties potentially payable pursuant to the terms of the share purchase agreement. We accounted for this acquisition as a business combination. 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 STD Pharmaceutical acquisition, which were included in selling, general and administrative expenses, were not material. The purchase price was preliminarily allocated as follows (in thousands):

Assets Acquired
Trade receivables	$	277
Inventories		843
Prepaid expenses and other assets		49
Intangible assets
Developed technology		10,428
Goodwill		4,975
Total assets acquired		16,572
Liabilities Assumed
Trade payables		(53)
Accrued expenses		(29)
Deferred income tax liabilities		(1,890)
Total liabilities assumed		(1,972)
Total net assets acquired	$	14,600

We are amortizing the developed technology intangible asset acquired in the STD Pharmaceutical acquisition over 12 years. The goodwill consists largely of the synergies we hope to achieve from combining operations and is not expected to be deductible for income tax purposes.

On June 14, 2019, we consummated an acquisition transaction contemplated by a merger agreement to acquire Brightwater Medical, Inc. ("Brightwater"). The purchase consideration consisted of an upfront payment of $35 million plus a final working capital adjustment of approximately $39,000, net of cash acquired, with potential earn-out payments of up to an additional $5 million for achievement of CE certification with respect to the Brightwater ConvertX®, a single-use device used to replace a series of devices and procedures used to treat severe obstructions of the ureter, and up to an additional $10 million for the achievement of sales milestones specified in the merger agreement. The ConvertX device is designed to be implanted once and converted from a nephroureteral catheter to a nephroureteral stent without requiring sedation or local anesthesia. Brightwater recently received FDA clearance for the ConvertX biliary stent device. We accounted for this acquisition as a business combination. 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

We are amortizing the developed technology intangible asset acquired in the Brightwater acquisition over 13 years, the related trademarks over five years and the customer list on an accelerated basis over one year. The total weighted-average amortization period for these acquired intangible assets is approximately 12.9 years. The goodwill consists largely of the synergies and economies of scale we hope to achieve from combining the acquired assets and operations with our historical operations and is not expected to be deductible for income tax purposes.

The pro forma impact of these acquisitions was not significant, either individually or in the aggregate, on our financial results for the three-month period ended March 31, 2019. Operating results attributable to the STD Pharmaceutical and Brightwater acquisitions were included in our consolidated statements of income (loss) for the three-month period ended March 31, 2020.

Total accumulated goodwill impairment losses aggregated to approximately $8.3 million as of March 31, 2020 and December 31, 2019. We did not have any goodwill impairments for the three-month periods ended March 31, 2020 and 2019. The total goodwill balance as of March 31, 2020 and December 31, 2019 was related to our cardiovascular segment.

Aggregate amortization expense for the three-month periods ended March 31, 2020 and 2019 was approximately $15.0 million and $14.8 million, respectively.

We evaluate long-lived assets, including amortizing intangible assets, for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. We perform the impairment analysis at the asset group for which the lowest level of identifiable cash flows is largely independent of the cash flows of other assets and liabilities. We compare the carrying value of the amortizing intangible assets acquired to the undiscounted cash flows expected to result from the asset group and determine whether the carrying amount is recoverable. We determine the fair value of our amortizing assets based on estimated future cash flows discounted back to their present value using a discount rate that reflects the risk profiles of the underlying activities. We did not identify indicators of impairment in any intangible assets based on our qualitative assessment for the three-month periods ended March 31, 2020 and 2019.

Estimated amortization expense for the developed technology and other intangible assets for the next five years consists of the following as of March 31, 2020 (in thousands):

Year Ending December 31,	Estimated Amortization Expense
Remaining 2020	$	44,365
2021		51,932
2022		50,625
2023		49,417
2024		46,465

7.   Income Taxes. Our provision for income taxes for the three-month periods ended March 31, 2020 and 2019 was a tax expense of approximately $1.2 million and $651,000, respectively, which resulted in an effective tax rate of

14

(58.3)% and 9.5%, respectively. The increase in the income tax expense and the corresponding change in the effective income tax rate for the three-month period ended March 31, 2020, when compared to the prior-year period, was primarily due to discrete expenses related to the fair value adjustment of the contingent consideration liabilities of recent equity acquisitions and the write-off of our purchase option to acquire Bluegrass Vascular Technologies, Inc. (“Bluegrass Vascular”) due to our decision not to exercise our option to purchase this business (see Note 14).

8.   Revolving Credit Facility and Long-Term Debt. Principal balances outstanding under our long-term debt obligations as of March 31, 2020 and December 31, 2019, consisted of the following (in thousands):

Third Amended and Restated Credit Agreement

On July 31, 2019, we entered into a Third Amended and Restated Credit Agreement (the "Third Amended Credit Agreement"). The Third Amended Credit Agreement is a syndicated loan agreement with Wells Fargo Bank, National Association and other parties. The Third Amended Credit Agreement amends and restates in its entirety our previously outstanding Second Amended and Restated Credit Agreement and all amendments thereto. The Third Amended Credit Agreement provides for a term loan of $150 million and a revolving credit commitment up to an aggregate amount of $600 million, inclusive of sub-facilities for multicurrency borrowings, standby letters of credit and swingline loans. On July 31, 2024, all principal, interest and other amounts outstanding under the Third Amended Credit Agreement are payable in full. At any time prior to the maturity date, we may repay any amounts owing under all term loans and revolving credit loans in whole or in part, without premium or penalty, other than breakage fees (as defined in the Third Amended Credit Agreement).

Revolving credit loans denominated in dollars and term loans made under the Third Amended Credit Agreement bear interest, at our election, at either the Base Rate or the Eurocurrency Rate (as such terms are defined in the Third Amended Credit Agreement) plus the Applicable Margin (as defined in the Third Amended Credit Agreement). Revolving credit loans denominated in an Alternative Currency (as defined in the Third 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 (as defined in the Third Amended Credit Agreement). Interest on each loan featuring the Base Rate is due and payable on the last business day of each calendar quarter; interest on each loan featuring the Eurocurrency Rate is due and payable on the last day of each interest period applicable thereto, and if such interest period extends over three months, at the end of each three-month interval during such interest period.

The Third Amended Credit Agreement is collateralized by substantially all our assets. The Third Amended Credit Agreement contains affirmative and negative covenants, representations and warranties, events of default and other terms

15

customary for loans of this nature. In particular, the Third Amended Credit Agreement requires that we maintain certain financial covenants, as follows:

	Covenant Requirement
Consolidated Total Leverage Ratio (1)		4.0 to 1.0
Consolidated Interest Coverage Ratio (2)		3.0 to 1.0
Facility Capital Expenditures (3)		$50 million

(1) Maximum Consolidated Total Net Leverage Ratio (as defined in the Third Amended Credit Agreement) as of any fiscal quarter end.

(2) Minimum ratio of Consolidated EBITDA (as defined in the Third Amended Credit Agreement and adjusted for certain expenditures) to Consolidated interest expense (as defined in the Third Amended Credit Agreement) for any period of four consecutive fiscal quarters.

(3) Maximum level of the aggregate amount of all Facility Capital Expenditures (as defined in the Third Amended Credit Agreement) in any fiscal year.

As of March 31, 2020, we believe we were in compliance with all covenants set forth in the Third Amended Credit Agreement.

As of March 31, 2020, we had outstanding borrowings of approximately $446.1 million under the Third Amended Credit Agreement, with additional available borrowings of approximately $232.1 million, based on the net leverage ratio required pursuant to the Third Amended Credit Agreement. Our interest rate as of March 31, 2020 was a fixed rate of 2.87% on $175 million as a result of an interest rate swap (see Note 9) and a variable floating rate of 2.74% on $271.1 million. Our interest rate as of December 31, 2019 was a fixed rate of 2.62% on $175 million as a result of an interest rate swap and a variable floating rate of 3.30% on $265 million.

Future minimum principal payments on our long-term debt as of March 31, 2020, were as follows (in thousands):

Years Ending	Future Minimum
December 31,	Principal Payments
Remaining 2020	$	5,625
2021		7,500
2022		8,438
2023		11,250
2024		413,312
Total future minimum principal payments	$	446,125

9.   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. For qualifying hedges, the change in fair value is deferred in accumulated other comprehensive income, a component of stockholders’ equity in the accompanying consolidated balance sheets, and recognized in earnings at the same time the hedged item affects earnings. Changes in the fair value of derivatives not designated as hedging instruments are recorded in earnings throughout the term of the derivative.

16

Interest Rate Risk. 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 Third Amended Credit Agreement that is solely due to changes in the benchmark interest rate.

Derivative Instruments Designated as Cash Flow Hedges

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

On December 23, 2019, we entered into a pay-fixed, receive-variable interest rate swap with a notional amount of $75 million with Wells Fargo to fix the one-month LIBOR rate at 1.71% for the period from July 6, 2021 to July 31, 2024. 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 will reset, the swap will be settled with the counterparty, and interest will be paid.

At March 31, 2020 and December 31, 2019, our interest rate swaps qualified as cash flow hedges. The fair value of our interest rate swaps at March 31, 2020 was a liability of approximately $4.8 million, which was partially offset by approximately $1.2 million in deferred taxes. The fair value of our interest rate swaps at December 31, 2019 was an asset of approximately $1.2 million, partially offset by approximately $307,000 in deferred taxes, and a liability of $(290,000), partially offset by approximately $(75,000) 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 Chinese Renminbi, Euros, British Pounds, Mexican Pesos, Brazilian Reals, Australian Dollars, Hong Kong Dollars, Swiss Francs, Swedish Krona, Canadian Dollars, Danish Krone, Japanese Yen, and South Korean Won, among others. 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.

Derivative Instruments Designated as Cash Flow Hedges

For derivative instruments that are designated and qualify as cash flow hedges, the gain or loss on the derivative instrument is temporarily reported as a component of other comprehensive income (loss) and then 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. We entered 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 150 cash flow foreign currency hedges every month. As of March 31, 2020 and December 31, 2019 we had entered into foreign currency forward contracts, which qualified as cash flow hedges, with notional amounts of $173.2 million and $212.5 million, respectively.

17

Derivative Instruments Not Designated as Cash Flow Hedges

We forecast our net exposure in various receivables and payables to fluctuations in the value of various currencies, and we enter into foreign currency forward contracts to mitigate that exposure. We enter into approximately 20 foreign currency fair value hedges every month. As of March 31, 2020 and December 31, 2019 we had entered into foreign currency forward contracts related to those balance sheet accounts with notional amounts of $65.2 million and $65.0 million, respectively.

Balance Sheet Presentation of Derivative Instruments. As of March 31, 2020 and December 31, 2019, all derivative instruments, 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.

10.   Commitments and Contingencies.

Loan Commitment. On October 11, 2019, we acquired shares of stock in Selio Medical Limited (“Selio”) representing  an ownership interest of approximately 19.5%, as well as an option to purchase all ordinary shares of Selio throughout a 45 day period commencing from the date Selio receives FDA 510(k) approval of a medical device it is currently developing, and an option to purchase all remaining shares of Selio on the third anniversary date of the agreement if we elect to purchase all ordinary shares. We have also made a loan of $250,000 to Selio and committed to provide additional loans of up to  €2 million at a rate of 5% per annum. Additional loans made to Selio pursuant to our loan agreement, together with the initial advance and all other amounts owed to us by Selio, would be securitized by Selio’s assets.

Litigation: In the ordinary course of business, we are involved in various claims and litigation matters. These claims and litigation matters may include actions involving product liability, intellectual property, contract disputes, and employment or other matters that are significant to our business. For example, in December 2019 our company, our Chief Executive Officer and our Chief Financial Officer were named in a complaint filed in the Central District of California, which alleges violations of certain federal securities laws. Based upon our review of currently available information, we do not believe that any such actions are likely to be, individually or in the aggregate, materially adverse to our business, financial condition, results of operations or liquidity.

In addition to the foregoing matters, in October 2016, we received a subpoena from the U.S. Department of Justice seeking information on certain of our marketing and promotional practices. We have responded to the subpoena, as well as additional related requests. We have incurred, and anticipate that we will continue to incur, substantial costs in connection with the matter. The investigation is ongoing and at this stage we are unable to predict its scope, duration or outcome. Investigations such as this may result in the imposition of, among other things, significant damages, injunctions, fines, or civil or criminal claims or penalties against our company or individuals. Legal expenses we incurred in responding to the

19

U.S. Department of Justice investigation for the three-month periods ended March 31, 2020 and 2019 were approximately $1.5 million and $1.7 million, respectively.

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

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

	Three Months Ended
	March 31,
	2020		2019
Net income (loss)	$	(3,154)	$	6,195
Average common shares outstanding		55,246		54,917
Basic EPS	$	(0.06)	$	0.11
Average common shares outstanding		55,246		54,917
Effect of dilutive stock options (1)		—		1,573
Total potential shares outstanding		55,246		56,490
Diluted EPS	$	(0.06)	$	0.11
Stock options excluded as the impact was anti-dilutive(1)		4,340		976

(1) For the three-month period ended March 31, 2020, 2,242 outstanding stock options were considered antidilutive due to the net loss in the period. Independent of the net loss incurred, the potentially dilutive effect of these options would have been 769 shares.

12.   Stock-Based Compensation Expense. Stock-based compensation expense before income tax expense for the three-month periods ended March 31, 2020 and 2019 consisted of the following (in thousands):

	Three Months Ended
	March 31,
	2020		2019
Cost of sales	$	339	$	252
Research and development		285		192
Selling, general and administrative		2,153		1,322
Stock-based compensation expense before taxes	$	2,777	$	1,766

Nonqualified Stock Options

During the three-month periods ended March 31, 2020 and 2019, we granted stock options representing 216,494 and 909,603 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 option grants, the fair value of our stock-based awards granted was estimated using the following assumptions for the periods indicated below:

	Three Months Ended
	March 31,
	2020	2019
Risk-free interest rate	0.52% - 1.67%	2.42% - 2.56%
Expected option term	4.0 - 5.0 years	3.0 - 5.0 years
Expected dividend yield	—	—
Expected price volatility	38.65% - 43.24%	28.93% - 33.69%

20

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 award. 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 term and implied volatility based on recent trends of the daily historical volatility. For awards with a vesting period, compensation expense is recognized on a straight-line basis over the service period, which corresponds to the vesting period.

We recognize stock-based compensation expense (net of a forfeiture rate) for those awards which are expected to vest on a straight-line basis over the requisite service period. We estimate the forfeiture rate based on our historical experience and expectations about future forfeitures. As of March 31, 2020, the total remaining unrecognized compensation cost related to non-vested stock options was approximately $28.4 million, which was expected to be recognized over a weighted average period of 2.93 years.

Stock-Settled Performance-Based Restricted Stock Units

During the three-month period ended March 31, 2020, we granted stock-settled performance-based restricted stock units (“performance stock units”) to certain of our executive officers representing up to 152,475 shares of our common stock. Conversion of the performance stock units occurs at the end of one, two and three-year performance periods, or one year after the agreement date, whichever is later. The conversion ratio is based upon attaining targeted levels of free cash flow (“FCF”) and relative shareholder return as compared to the Russell 2,000 (“rTSR”), as defined in the award agreements. The payout for each unit is equal to one share of common stock multiplied by a FCF multiplier (between 0% and 200%) and a rTSR multiplier (between 75% and 125%). If FCF is below a specified threshold, no shares will be awarded. The potential maximum payout per performance stock units is 250% of the target shares. Performance stock units convey no shareholder rights, including voting rights, unless and until shares are issued in settlement of the award. As performance stock units represent contingently issuable shares, we have excluded them from the calculation of weighted average shares outstanding for the calculation of diluted EPS.

We use Monte-Carlo simulations to estimate the grant-date fair value of the performance stock units linked to total shareholder return. The fair value of each performance stock unit was estimated using the following assumptions for the periods indicated below:

	Three Months Ended
	March 31,
	2020
Risk-free interest rate	1.1% - 1.3%
Performance period	0.8 - 2.8 years
Expected dividend yield	—
Expected price volatility	40.2% - 56.1%

The risk-free interest rate of return was determined using the U.S. Treasury rate at the time of grant with a remaining term equal to the expected term of the award. The expected volatility was based on a weighted average volatility of our stock price and the average volatility of our compensation peer group's volatilities. The expected dividend yield was assumed to be zero because, at the time of the grant, we had no plans to declare a dividend.

Compensation expense is recognized using the grant-date fair value for the number of shares that are probable of being awarded based on the performance conditions. Each reporting period, this probability assessment is updated, and cumulative catchups are recorded based on the level of FCF that is expected to be achieved. At the end of the performance period, cumulative expense is calculated based on the final number of shares awarded. For the three-month period ended March 31, 2020, we recognized stock-based compensation expense associated with the performance stock units of approximately $0.3 million. As of March 31, 2020, the total remaining unrecognized compensation cost related to performance stock units was approximately $5.0 million, which is expected to be recognized over a weighted average period of 1.83 years.

21

Cash-Settled Performance-Based Share-Based Awards

During the three-month period ended March 31, 2020, we granted cash-settled performance-based share-based awards to our Chief Executive Officer. These awards entitle him to a cash payment equal to a target cash incentive multiplied by rTSR and FCF multipliers, as defined in the award agreements. The potential maximum payout is 250% of the target cash incentive. Settlement generally occurs at the end of one, two and three-year performance periods based upon the same performance metrics and vesting period as our performance stock units.

For the three-month period ended March 31, 2020, we recognized expense associated with these cash-settled performance-based restricted stock units of approximate $0.1 million within selling, general and administrative expenses in our consolidated statement of income (loss). The fair value of these awards will be remeasured at each reporting period until the awards are settled. These awards are classified as liabilities and reported in accrued expenses and other long-term assets within our consolidated balance sheet. As of March 31, 2020, the total remaining unrecognized compensation cost related to cash-settled performance-based share-based awards was approximately $2.2 million, which is expected to be recognized over a weighted average period of 1.83 years.

13.   Segment Reporting. We report our operations in two operating segments: cardiovascular and endoscopy. Our cardiovascular segment consists of four product categories: peripheral intervention, cardiac intervention, custom procedural solutions, and OEM. Within these product categories, we sell a variety of products, including cardiology and radiology devices (which assist in diagnosing and treating coronary arterial disease, peripheral vascular disease and other non-vascular diseases), as well as embolotherapeutic, cardiac rhythm management, electrophysiology, critical care, breast cancer localization and guidance, biopsy, 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.

14.   Fair Value Measurements.

Assets (Liabilities) Measured at Fair Value on a Recurring Basis

Our financial assets and (liabilities) carried at fair value measured on a recurring basis as of March 31, 2020 and December 31, 2019, consisted of the following (in thousands):

			Fair Value Measurements Using

(1) The fair value of the interest rate contracts is determined using Level 2 fair value inputs and is recorded as other long-term assets or other long-term obligations 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 current assets or other long-term assets 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 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 or other milestones. See Note 4 for further information regarding these acquisitions. The contingent consideration liability is re-measured at the estimated fair value at the end of each reporting period with the change in fair value recognized within operating expenses in the accompanying consolidated statements of income (loss) for such period. We measure the initial liability and re-measure the liability on a recurring basis using Level 3 inputs as defined under authoritative guidance for fair value measurements.

Changes in the fair value of our contingent consideration liabilities during the three-month periods ended March 31, 2020 and 2019, consisted of the following (in thousands):

	Three Months Ended
	March 31,
	2020		2019
Beginning balance	$	76,709	$	82,236
Contingent consideration expense (1)		4,897		775
Contingent payments made		(12,754)		(554)
Effect of foreign exchange		17		—
Ending balance	$	68,869	$	82,457
(1) There were no fair value adjustments recorded to OCI for the three months ended March 31, 2020

As of March 31, 2020, approximately $57.6 million in contingent consideration liability was included in other long-term obligations and approximately $11.3 million in contingent consideration liability was included in accrued expenses in our consolidated balance sheet. As of December 31, 2019, approximately $48.1 million in contingent consideration liability was included in other long-term obligations and approximately $28.6 million in contingent consideration liability was included in accrued expenses in our consolidated balance sheet. Cash paid to settle the contingent consideration liability recognized at fair value as of the applicable acquisition date (including measurement-period adjustments) has been reflected as a cash outflow from financing activities in the accompanying consolidated statements of cash flows.

During the year ended December 31, 2016, we sold an equity investment for cash and for the right to receive additional payments based on various contingent milestones. We determined the fair value of the contingent payments using Level 3 inputs defined under authoritative guidance for fair value measurements, and we recorded a contingent receivable asset. During the three-month period ended March 31, 2019, we recorded a gain on the contingent receivable of approximately $20,000. As of December 31, 2019, the contingent receivable was settled in full and there was no balance remaining to collect.

The recurring Level 3 measurement of our contingent consideration liabilities included the following significant unobservable inputs at March 31, 2020 and December 31, 2019 (amounts in thousands):

	Fair value at
	March 31,		Valuation
Contingent consideration liability	2020		technique	Unobservable inputs	Range	Weighted Average(1)
Revenue-based royalty payments contingent liability	$	8,053	Discounted cash flow	Discount rate	12% - 24%	15.4%
				Projected year of payments	2020-2034	2026
Revenue milestones contingent liability	$	58,116	Monte Carlo simulation	Discount rate	9% - 14.5%	10.9%
				Projected year of payments	2020-2023	2022
Regulatory approval contingent liability	$	2,700	Scenario-based method	Discount rate	6.6%
				Probability of milestone payment	65%
				Projected year of payment	2022
(1) Unobservable inputs were weighted by the relative fair value of the instruments. No weighted average is reported for unobservable inputs related to a single financial asset or liability.

24

	Fair value at
	December 31,		Valuation
Contingent consideration liability	2019		technique	Unobservable inputs	Range
Revenue-based royalty payments contingent liability	$	7,710	Discounted cash flow	Discount rate	13% - 24%
				Projected year of payments	2020-2034
Revenue milestones contingent liability	$	66,114	Monte Carlo simulation	Discount rate	9% - 13.5%
				Projected year of payments	2020-2023
Regulatory approval contingent liability	$	2,885	Scenario-based method	Discount rate	2.4%
				Probability of milestone payment	65%
				Projected year of payment	2022

The contingent consideration liability is re-measured to fair value each reporting period. Significant increases or decreases in projected revenues, based on our most recent internal operational budgets and long-range strategic plans, discount rates or the time until payment is made would have resulted in a significantly lower or higher fair value measurement. Our determination of the fair value of the contingent consideration liability could change in future periods based upon our ongoing evaluation of these significant unobservable inputs. We intend to record any such change in fair value to operating expenses in our consolidated statements of income (loss).

Fair Value of Other Financial Instruments

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

We recognize or disclose the fair value of certain assets, such as non-financial assets, primarily property and equipment, intangible assets and goodwill in connection with impairment evaluations. All our nonrecurring valuations use significant unobservable inputs and therefore fall under Level 3 of the fair value hierarchy. During the three-month period ended March 31, 2020, we recorded impairment charges of approximately $359,000, related to certain property and equipment associated with our sale of the NvisionVLE® Imaging System under our distribution agreement with NinePoint Medical, Inc. (“NinePoint”). In addition, during the three-month periods ended March 31, 2020 and 2019, we had losses of approximately $81,000 and $211,000, respectively, related to the measurement of other non-financial assets at fair value on a nonrecurring basis subsequent to their initial recognition.

Our equity investments in privately held companies, including options to acquire these companies, were $14.5 million and $17.1 million at March 31, 2020 and December 31, 2019, respectively. We analyze our investments in privately-held companies to determine if they should be accounted for using the equity method based on our ability to exercise significant influence over operating and financial policies of the investment. Investments not accounted for under the equity method of accounting are accounted for at cost minus impairment, if applicable, plus or minus changes in valuation resulting from observable transactions for identical or similar investments. During the three-month period ended March 31, 2020 we recorded charges of $3.5 million due to our write-off of our purchase option to acquire Bluegrass Vascular due to our  decision not to exercise our option to purchase the business.

Our outstanding long-term notes receivable, including accrued interest, and in 2020 our allowance for current expected credit losses, were approximately $2.1 million and $2.7 million as of March 31, 2020 and December 31, 2019, respectively. As of March 31, 2020, we recognized an allowance for current expected credit losses of $670,000 associated with these notes receivable and our contractual obligation to extend credit to Selio. We assess the allowance for current expected credit losses on an individual security basis, due to the limited number of securities, using a probability of default model,

25

which is based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the expected collectability of securities. During the first quarter of 2020, we adjusted the probability of default for all securities for a period of one year due to changes in current macroeconomic conditions and our expectations of collectability.

The table below presents a rollforward for the period ended March 31, 2020 of the allowance for current expected credit losses on our notes receivable (in thousands):

16. Subsequent Events.

COVID-19 Pandemic

In December 2019, a novel strain of coronavirus (“COVID-19”) surfaced in Wuhan, China. In March 2020, the World Health Organization classified the COVID-19 outbreak as a pandemic, and the virus has spread to most countries and to all 50 states within the United States. The COVID-19 pandemic has created significant uncertainty in the global economy, has negatively impacted our business, results of operations and financial condition, and we anticipate that it may negatively impact our business, results of operations and financial condition for the foreseeable future. At present, it is not possible for us to predict the extent of this impact due to uncertainties regarding the duration of the pandemic, potential government mandates regarding elective procedures, and patient behavior, among other factors.

In response to the COVID-19 pandemic, we implemented certain cost reduction and operating efficiency initiatives, including decreased discretionary spending, delayed product launches, and deferred capital spending and research and development projects, among other initiatives. In April 2020, due to the significant impact of the COVID-19 pandemic on our business, results of operations and financial condition, and uncertainly regarding the scope and duration of that impact, we implemented furloughs and a temporary salary reduction for executive management and certain other salaried personnel. We also implemented processes to encourage the safety of our employees, including formal policies restricting travel, temperature screenings at most of our manufacturing locations, and mandatory telecommuting for certain positions.

As the impact of the COVID-19 pandemic evolves, we will continue to assess the impact on our business and respond accordingly. Sustained adverse impacts to our business, our suppliers, and our customers may also affect our future valuation of certain assets and therefore may increase the likelihood of an impairment charge, write-off, or reserve associated with such assets, including goodwill, finite-lived intangible assets, property and equipment, inventories, accounts receivable, tax assets, and other assets. Estimates may change as new events occur and additional information is obtained, and actual results will likely differ, and may differ materially, from our estimates under different assumptions, circumstances or conditions.

Disclosure Regarding Trademarks

This report includes trademarks, tradenames and service marks that are our property or the property of others. Solely for convenience, such trademarks and tradenames sometimes appear without any “™” or “®” symbol. However, failure to include such symbols is not intended to suggest, in any way, that we will not assert our rights or the rights of any applicable licensor, to these trademarks and tradenames.

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 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 four product categories: peripheral intervention, cardiac intervention, custom procedural solutions, and OEM. Within these product categories, we sell a variety of products, including cardiology and radiology devices (which assist in diagnosing and treating coronary arterial disease, peripheral vascular disease and other non-vascular diseases), as well as embolotherapeutic, cardiac rhythm management, electrophysiology, critical care, breast cancer localization and guidance, biopsy, 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.

30

For the three-month period ended March 31, 2020, we reported sales of approximately $243.5 million, up approximately $5.2 million or 2.2%, over sales from the three-month period ended March 31, 2019 of approximately $238.3 million.

Gross profit as a percentage of sales decreased to 42.6% for the three-month period ended March 31, 2020 as compared to 43.9% for the three-month period ended March 31, 2019.

Net loss for the three-month period ended March 31, 2020 was approximately $(3.2) million, or $(0.06) per share, as compared to net income of approximately $6.2 million, or $0.11 per share, for the three-month period ended March 31, 2019.

Recent Developments and Trends

In addition to the trends identified in the 2019 Form 10-K under the heading “Management’s Discussion and Analysis of Financial Condition and Results of Operations - Overview,” our business in 2020 has been impacted, and we believe it will continue to be impacted by the following recent events and trends:

● Despite the challenges presented by the COVID-19 pandemic during the three months ended March 31 2020, we continued to implement initiatives we have been working on for several months. We are in the process of moving 14 products to our Tijuana, Mexico and Pearland, Texas facilities, as well as consolidating four satellite facilities.

● Sales in many of our end markets declined during the three months ended March 31, 2020 due, in large part, to the imposed limitations of hospital procedures required to devote limited resources to COVID-19 treatment. At the same time, we saw increased demand for many of our critical care products, such as hemodynamic monitoring, peritoneal dialysis catheters and insertion tools, as well as our infection control products.

● At present, we expect a number of previously announced new product launches will be delayed due to the COVID-19 pandemic. However, in April 2020 we initiated production of a nasopharyngeal swab and transport vial, used to collect specimens with suspected presence of COVID-19. We received our first purchase order of $2.4 million from the State of Utah in April 2020.

● We have actively managed inventory levels, reduced executive management and other employee compensation, limited discretionary spending and delayed capital spending.

● As of March 31, 2020, we had cash on hand of approximately $50 million and net borrowing capacity of approximately $232.1 million, which was undrawn as of March 31, 2020.

Sales

Sales for the three-month period ended March 31, 2020 increased by 2.2%, or approximately $5.2 million, compared to the corresponding period in 2019. Listed below are the sales by product category within each of our financial reporting segments for the three-month periods ended March 31, 2020 and 2019 (in thousands, other than percentage changes):

			Three Months Ended
			March 31,

Cardiovascular Sales. Our cardiovascular sales for the three-month period ended March 31, 2020 were approximately $235.5 million, up 2.2% when compared to the corresponding period of 2019 of approximately $230.5 million. Sales for the three-month period ended March 31, 2020 were favorably affected by increased sales of:

(a) Peripheral intervention products (particularly our access and drainage products, offset partially by angiography and vertebral compression fracture products) of approximately $2.4 million, up 2.9% from the corresponding period of 2019;

(b) Custom procedural solutions products (particularly our trays and critical care products, many of which saw increased demand due to COVID-19, offset partially by decreased kit sales) of approximately $1.8 million, up 3.8% from the corresponding period of 2019; and

(c) OEM products (particularly custom procedural solutions and cardiac intervention products, offset partially by sensors) of approximately $0.8 million, up 3.0% from the corresponding period of 2019.

Endoscopy Sales. Our endoscopy sales for the three-month period ended March 31, 2020 were approximately $8.0 million, up 1.4%, when compared to sales in the corresponding period of 2019 of approximately $7.9 million. Sales for the three-month period ended March 31, 2020 were favorably affected by sales of our AEROmini® and EndoMAXX® Fully Covered Esophageal Stents.

International Sales. International sales for the three-month period ended March 31, 2020 were approximately $102.5 million, or 42.1% of net sales, up 2.2% when compared to the corresponding period of 2019. The increase in our international sales for the first quarter of 2020 compared to the first quarter of 2019 was primarily related to sales increases in Turkey of approximately $4.1 million, South Africa of approximately $0.9 million, Italy of approximately $0.8 million, Australia of approximately $0.6 million, and Germany of approximately $0.5 million, partially offset by decreased sales primarily driven by decreased demand due to the COVID-19 pandemic in China of approximately $(5.0) million and Japan of  $(0.7) million.

Gross Profit

Our gross profit as a percentage of sales decreased to 42.6% for the three-month period ended March 31, 2020, compared to 43.9% for the three-month period ended March 31, 2019. The decrease in gross profit percentage was primarily due to changes in product mix driven by the COVID-19 pandemic (as sales were down in China, a market which typically

32

generates gross margins which are higher than our corporate average) and increased obsolescence expense primarily due to reserves of inventory sold under our distribution agreement with NinePoint, partially offset by improvements in manufacturing variances from operational efficiencies.

Operating Expenses

Selling, General and Administrative Expense. Selling, general and administrative ("SG&A") expenses increased approximately $0.5 million, or 0.7%, for the three-month period ended March 31, 2020 compared to the three-month period ended March 31, 2019. As a percentage of sales, SG&A expenses were 32.4% of sales for the three-month period ended March 31, 2020, compared to 32.8% for the three-month period ended March 31, 2019. In the three months ended March 31, 2020 compared to the corresponding period of 2019, overall compensation expenses were higher (including increased severance and offset by lower bonus expense), bad debt expense increased by approximately $0.9 million (primarily as a result of the COVID-19 pandemic and increased credit sales to distributors in the Middle East), and discretionary spending decreased (including reduced travel, training, and shows and conventions expenses as a result of restrictions related to the COVID-19 pandemic).

Research and Development Expenses. Research and development ("R&D") expenses for the three-month period ended March 31, 2020 were approximately $14.9 million, down (7.3)%, when compared to R&D expenses in the corresponding period of 2019 of approximately $16.0 million. This decrease in R&D expenses was largely due to headcount reductions and lower discretionary expenses related to the COVID-19 pandemic.

Operating Income (Loss)

The following table sets forth our operating income (loss) by financial reporting segment for the three-month periods ended March 31, 2020 and 2019 (in thousands):

	Three Months Ended
	March 31,
	2020		2019
Operating Income (Loss)
Cardiovascular	$	1,502	$	7,619
Endoscopy		(140)		1,904
Total operating income	$	1,362	$	9,523

Cardiovascular Operating Income. Our cardiovascular operating income for the three-month period ended March 31, 2020 was approximately $1.5 million, compared to operating income of approximately $7.6 million for the three-month period ended March 31, 2019. The decrease in cardiovascular operating income was primarily a result of increased impairment expense of $3.8 million related to an option to purchase Bluegrass Vascular, which expired unexercised, higher contingent consideration expense from fair value adjustments related to liabilities from completed acquisitions and lower gross margins, partially offset by higher sales.

Endoscopy Operating Income (Loss). Our endoscopy operating loss for the three-month period ended March 31, 2020 was approximately $(0.1) million, compared to operating income of approximately $1.9 million for the three-month period ended March 31, 2019. This decrease was primarily the result of lower gross margins due to $1.4 million of inventory obsolescence related to products sold under our distribution agreement with NinePoint.

Effective Tax Rate

Our effective income tax rate for the three-month periods ended March 31, 2020 and 2019 was (58.3)% and 9.5%, respectively. The increase in the income tax expense and the corresponding change in the effective income tax rate for the three-month period ended March 31, 2020, when compared to the prior-year period, was primarily due to discrete expenses related to the fair value adjustment of the contingent consideration liabilities of recent equity acquisitions and the write-off of our purchase option to acquire Bluegrass Vascular, due to our decision not to exercise our option to purchase this business.

33

Other Expense

Our other expense for the three-month periods ended March 31, 2020 and 2019 was approximately $3.4 million and $2.7 million, respectively. The increase in other expense was primarily a result of increased interest expense as a result of higher average debt balances.

Net Income (Loss)

Our net income (loss) for the three-month periods ended March 31, 2020 and 2019 was approximately $(3.2) million and $6.2 million, respectively. The decrease in net income was primarily due to lower gross margins, higher contingent consideration expense from fair value adjustments related to liabilities from recent acquisitions, and higher impairment and other charges, partially offset by increased sales and reduced expenses from certain cost-cutting initiatives.

LIQUIDITY AND CAPITAL RESOURCES

Capital Commitments, Contractual Obligations and Cash Flows

At March 31, 2020 and December 31, 2019, we had cash and cash equivalents of approximately $50.1 million and $44.3 million respectively, of which approximately $37.3 million and $31.7 million, respectively, were held by foreign subsidiaries. We currently believe future repatriation of cash and other property held by our foreign subsidiaries will generally not be subject to U.S. federal income tax. As a result, after evaluation of the permanent reinvestment assertion, we are not permanently reinvested with respect to our historic unremitted foreign earnings. 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, 2020, and December 31, 2019, we had cash and cash equivalents of approximately $14.5 million and $11.3 million, respectively, within our subsidiary in China.

Cash flows provided by operating activities. We generated cash from operating activities of approximately $28.9 million and $13.5 million during the three-month periods ended March 31, 2020 and 2019, respectively. Net cash provided by operating activities increased approximately $15.4 million for the three-month period ended March 31, 2020 compared to the three-month period ended March 31, 2019. Significant changes in operating assets and liabilities affecting cash flows during these years included:

● Net income (loss) was approximately $(3.2) million and $6.2 million for the three-month periods ended March 31, 2020 and 2019, respectively. The loss recognized in the three-month period ended March 31, 2020 was primarily attributable to increased non-cash expenses including $3.9 million for the write-off of certain intangible and other long-term assets principally associated with the expiration of our option to purchase Bluegrass Vascular and $4.9 million for fair value adjustments to our contingent consideration liabilities, and

● Cash provided by (used for) accounts receivable was approximately $3.4 million and $(11.6) million for the three-month periods ended March 31, 2020 and 2019, respectively, due primarily to timing of collections and increased allowances due to economic uncertainty, partially offset by increases in sales volume.

Cash flows used in investing activities. We used cash in investing activities of approximately $14.8 million and $21.0 million for the three-month periods ended March 31, 2020 and 2019, respectively. We invested in capital expenditures for property and equipment of approximately $14.0 million and $18.3 million in the three-month periods ended March 31, 2020 and 2019, respectively. Capital expenditures in each fiscal year were primarily related to investment in buildings, property and equipment to support development and production of new and expanded product lines and to facilitate growth in our distribution markets. These investments include construction of a new manufacturing and research and development facility in South Jordan, Utah completed in early 2020. Historically, we have incurred significant expenses in connection with facility construction, production automation, product development and the introduction of new products. We anticipate that we will spend approximately $50 to $55 million in 2020 for buildings, property and equipment.

34

Cash outflows invested in acquisitions for the three-month periods ended March 31, 2019 were approximately $1.9 million and were primarily related to our investment in the equity of Fluidx Medical Technology, LLC. There was no cash paid for acquisitions in the three-month period ended March 31, 2020.

Cash flows used in financing activities. Cash used in financing activities for the three-month periods ended March 31, 2020 and 2019 was approximately $6.2 million and $9.8 million, respectively. In 2020 we increased our net borrowings by approximately $6.1 million to partially finance the payment of contingent consideration of $12.8 million, which is classified as a financing activity, principally related to our acquisition of Cianna Medical, Inc. In 2019, our primary financing activities included additional net borrowings under our credit agreement to partially fund our acquisition activity and capital expenditures for property and equipment.

As of March 31, 2020, we had outstanding borrowings of approximately $446.1 million under the Third Amended Credit Agreement, with additional available borrowings of approximately $232.1 million, based on the leverage ratio required pursuant to the Third Amended Credit Agreement. Our interest rate as of March 31, 2020 was a fixed rate of 2.87% on $175 million as a result of an interest rate swap (see Note 9 to our consolidated financial statements included in Part I, Item 1 of this report) and a variable floating rate of 2.74% on $271.1 million. Our interest rate as of December 31, 2019 was a fixed rate of 2.62% on $175 million as a result of an interest rate swap and a variable floating rate of 3.30% on $265 million. See Note 8 to our consolidated financial statements included in Part I, Item 1 of this report for additional details regarding the Third Amended Credit Agreement and our long-term debt.

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

Off-Balance Sheet Arrangements

We have committed to provide loans of up to an additional €2 million at the discretion of Selio at a rate of 5% per annum. The current note receivable balance from Selio is $250,000. Additional loans made to Selio pursuant to our loan agreement, together with the initial advance and all other amounts owed to us by Selio, would be securitized by Selio’s assets. Aside from this arrangement, we do not have any off-balance sheet arrangements that have had, or are reasonably likely in the future to have, an effect on our financial condition, results of operations, liquidity, capital expenditures or capital resources.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

Our financial results are affected by the selection and application of accounting policies and methods. In the three months ended March 31, 2020, there were no changes to the application of critical accounting policies previously disclosed in Part II, Item 7 of the 2019 Form 10-K.

35

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Currency Risk

Our principal market risk relates to changes in the value of the following currencies relative to the U.S. Dollar (USD):

● Chinese Yuan Renminbi (CNY) and

● Euro (EUR)

We also have more limited market risk relating to the following currencies (among others):

● British Pound (GBP),

● 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),

● South Korean Won (KRW), and

● Japanese Yen (JPY).

Our consolidated financial statements are denominated in, and our principal currency is, the USD. For the three-month period ended March 31, 2020, a portion of our net sales (approximately $75.5 million, representing approximately 31.0% of our aggregate net sales), was attributable to sales that were denominated in foreign currencies. All other international sales were denominated in USD.

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

	USD Relative to Other Currency
	10% Strengthening		10% Weakening
Impact to Operating Income:
CNY	$	(8,880)	$	8,880
EUR	$	5,053	$	(5,053)

36

During the three-month period ended March 31, 2020, exchange rate fluctuations of foreign currencies against the USD had the following impact on our sales, cost of sales and gross profit (in thousands, except percentages):

	Three Months Ended
	March 31, 2020
	Currency Impact to Reported Amounts
	Increase/(Decrease)		Percent Increase/(Decrease)
Net sales	$	(2,802)	(1.1)	%
Cost of sales	$	(400)	(0.3)	%
Gross profit (1)	$	(2,402)	(2.3)	%

(1) Represents approximately 49 basis points in gross margin percentage for the three-month period ended March 31, 2020

The impact to sales for the three-month period ended March 31, 2020 was primarily a result of unfavorable impacts due to sales denominated in EUR, CNY and BRL. The impact to cost of sales was primarily a result of favorable impacts from EUR fluctuations related to manufacturing costs from our facilities in Europe denominated in EUR.

We forecast our net exposure related to sales and expenses denominated in foreign currencies. As of March 31, 2020 and December 31, 2019 we had entered into foreign currency forward contracts, which qualified as cash flow hedges, with notional amounts of $173.2 million and $212.5 million, respectively.

We also forecast our net exposure in various receivables and payables to fluctuations in the value of various currencies, and we enter into foreign currency forward contracts to mitigate that exposure. As of March 31, 2020 and December 31, 2019 we had entered into foreign currency forward contracts (which were not designated as hedging instruments) related to those balance sheet accounts with notional amounts of $65.2 million and $65.0 million, respectively.

See Note 9 to our consolidated financial statements included in Part I, Item 1 of this report for a discussion of our foreign currency forward contracts.

Interest Rate Risk. As discussed in Note 8 to our consolidated financial statements included in Part 1, Item 1 of this report, as of March 31, 2020, we had outstanding borrowings of approximately $446.1 million under the Third Amended Credit Agreement. Our earnings and after-tax cash flow are affected by changes in interest rates. On August 5, 2016, we entered into a pay-fixed, receive-variable interest rate swap with Wells Fargo, which as of March 31, 2020 had a notional amount of $175 million, to fix the one-month LIBOR rate at 1.12%. The interest rate swap is scheduled to expire on July 6, 2021. This instrument is intended to reduce our exposure to interest rate fluctuations and was not entered into for speculative purposes. Excluding the amount that is subject to a fixed rate under the interest rate swap and assuming the current level of borrowings remained the same, it is estimated that our interest expense and income before income taxes would change by approximately $2.7 million annually for each one percentage point change in the average interest rate under these borrowings.

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

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our management is responsible for establishing and maintaining adequate disclosure controls and procedures for our company. Consequently, our management, with the participation of our chief executive officer and chief financial officer, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15 under the Exchange Act as

37

of March 31, 2020. In designing and evaluating the disclosure controls and procedures, management recognized that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Based on that evaluation, our chief executive officer and chief financial officer concluded that our disclosure controls and procedures are designed at a reasonable assurance level and are effective to provide reasonable assurance that information we are required to disclose in reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in Securities and Exchange Commission rules and forms, and that such information is accumulated and communicated to our management, including our chief executive officer and chief financial officer, as appropriate, to allow timely decisions regarding required disclosure.

Changes in Internal Control Over Financial Reporting

During the quarter ended March 31, 2020, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f) under the Securities Exchange Act of 1934).

PART II - OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

See Note 10 “Commitments and Contingencies” set forth in the notes to our consolidated financial statements included in Part I, Item 1 of this report.

ITEM 1A. RISK FACTORS

In addition to other information set forth in this report, readers should carefully consider the factors discussed in Part I, Item 1A. "Risk Factors" of the 2019 Form 10-K, as well as the amended and updated risk factors included below (which replace the equivalent risk factors disclosed in Part I, Item 1A. "Risk Factors" of the 2019 Form 10-K). Such risk factors could materially affect our business, financial condition or future results. The risks described in our 2019 Form 10-K are not the only risks we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially and adversely affect our business, financial condition and/or operating results.

The COVID-19 pandemic has negatively impacted our business and operations around the world and may continue to materially and adversely impact our business, operations and financial results.

In December 2019, a novel strain of coronavirus surfaced in Wuhan, China. Since then, this virus and the resulting disease COVID-19, has spread to most countries, and all 50 states within the United States. The COVID-19 pandemic has created significant uncertainty in the global economy, has negatively impacted our business, results of operations and financial condition, and we anticipate that it may negatively impact our business, results of operations and financial condition for the foreseeable future. Elective procedures that use our products have significantly decreased in number as health care organizations around the world have prioritized the treatment of patients with COVID-19. For example, in the United States, governmental authorities have recommended, and in certain cases required, that elective, specialty and other procedures and appointments, be suspended or canceled to avoid non-essential patient exposure to medical environments and potential infection with COVID-19 and to focus limited resources and personnel capacity toward the treatment of COVID-19 patients. Specifically, many of these procedures that use our products have been suspended or postponed and it is unclear when these procedures will resume. In addition, most of the hospitals and clinics that purchase our products have instituted strict procedures at their facilities in an effort to prevent the spread of COVID-19, including restrictions on sales representatives entering these facilities. This has been a major impediment to our sales efforts, as supporting existing customers and acquiring new customers is much more difficult in this environment. These restrictions have had a significant adverse effect on our sales and, until they are lifted, our business, operations and financial results continue to be adversely impacted. These measures and challenges will likely continue for the duration of the pandemic, which is uncertain, and are likely to continue to reduce our revenue and negatively impact our business, operations and financial results. Further, once the pandemic subsides, we anticipate there will be substantial backlog of patients seeking appointments with physicians and surgeries to be performed at hospitals and ambulatory surgery centers relating to a variety of medical conditions, and as a result, patients seeking procedures that use our products will have to navigate limited provider capacity. We believe this limited provider, hospital and ambulatory surgery center capacity could have a significant adverse effect on our business, operations and financial results following the end of the pandemic.

Numerous national, international, state and local jurisdictions have imposed, and others in the future may impose, "shelter-in-place" orders, quarantines, executive orders and similar government orders and restrictions for their residents to control the spread of COVID-19. Such orders or restrictions have resulted in significant alteration of our operations, work stoppages, slowdowns and delays, travel restrictions and cancellation of events, among other effects, thereby significantly and negatively impacting our operations. Other disruptions or potential disruptions include (i) restrictions on our personnel and personnel of business partners to travel and access customers for training and case support; (ii) delays in approvals by regulatory bodies; (iii) diversion of or limitations on employee resources that would otherwise be focused on the operations of our business, including because of sickness of employees or their families or the desire of employees to avoid contact with large groups of people; (iv) reductions in our sales team, including through layoffs, furloughs or other losses of sales representatives; (v) additional government requirements or other incremental mitigation efforts that may further impact our or our suppliers' capacity to manufacture our products; (vi) disruption of our research and development activities; and (vii) delays in ongoing studies and pre-clinical trials. The extent to which the COVID-19 pandemic impacts our business

39

will depend on future developments, which are highly uncertain and cannot be predicted, including new information which may emerge concerning the severity and spread of COVID-19 and the actions by government entities and our customers to contain COVID-19 or treat its impact, among others.

The extent to which the COVID-19 pandemic impacts our business, operations and financial results will depend on future developments that are uncertain and cannot be predicted, including new information that may emerge concerning the severity of the virus and actions taken to contain its impact. To the extent the COVID-19 pandemic adversely affects our business, operations and financial results, it may also have the effect of heightening other risks described in “Risk Factors” in our 2019 Form 10-K, such as those relating to general economic conditions, demand for our products, relationships with suppliers and sales efforts.

Changes in general economic conditions, geopolitical conditions, U.S. trade policies and other factors beyond our control may adversely impact our business and operating results.

Our operations and performance depend significantly on global, regional and U.S. economic and geopolitical conditions. In recent years, there has been discussion and dialogue regarding potential significant changes to U.S. trade policies, legislation, treaties and tariffs, including the North American Free Trade Agreement (“NAFTA”). In January 2020, after passing the House and Senate, President Trump signed the United States Mexico Canada Agreement (“USMCA”). Mexico had already ratified the USMCA, but before it can take effect, Canada must also ratify the USMCA. At this time, it is unknown whether Canada will ratify the USMCA, new legislation will be passed into law, pending or new regulatory proposals will be adopted, other international trade agreements will be negotiated, or the effect that any such action would have, either positively or negatively, on our industry or our Company. If the USMCA is fully ratified, any new legislation and/or regulations are implemented, or if existing trade agreements are renegotiated, it may be inefficient and expensive for us to alter our business operations in order to adapt to or comply with such changes. Such operational changes could have a material adverse effect on our business, operations and financial results.

Recently, the COVID-19 pandemic has significantly impacted our business operations around the world. The adverse impact of the COVID-19 pandemic on our net sales during the first quarter of 2020 was approximately $16 million. While the potential economic impact brought by and the duration of COVID-19 is difficult to assess or predict, the widespread pandemic has resulted in, and may continue to result in, significant disruption of global financial markets, reducing our ability to access capital, which could in the future negatively affect our liquidity. In addition, a recession or market correction resulting from the spread of COVID-19 could materially affect our business. The COVID-19 pandemic has also resulted in a significant increase in unemployment in the United States which may continue even after the pandemic. The occurrence of any such events may lead to reduced disposable income, access to healthcare and availability of health insurance coverage, which could adversely affect the number and mix of our products sold after the pandemic has ended.

In addition to changes in U.S. trade policy and the COVID-19 pandemic, a number of other economic and geopolitical factors both in the U.S. and abroad could have a material adverse effect on our business, financial condition, results of operations or cash flows, which could ultimately result in:

● a global or regional economic slowdown in any of our market segments;

● postponement of spending, in response to tighter credit, financial market volatility and other factors;

● effects of significant changes in economic, monetary and fiscal policies in the U.S. and abroad including significant income tax changes, currency fluctuations and inflationary pressures;

● rapid material escalation of the cost of regulatory compliance and litigation;

● changes in government policies and regulations affecting the Company or its significant customers;

● industrial policies in various countries that favor domestic industries over multinationals or that restrict foreign companies altogether;

● difficulties protecting intellectual property;

● new or stricter trade policies and tariffs affecting China;

40

● longer payment cycles;

● credit risks and other challenges in collecting accounts receivable; and

● the impact of each of the foregoing on outsourcing and procurement arrangements.

In addition, any changes in U.S. trade policy could trigger retaliatory actions by affected countries, such as China, resulting in a “trade war.” A trade war could result in increased costs for raw materials we use in our manufacturing and could result in foreign governments imposing tariffs on products that we export outside the U.S. or otherwise limiting our ability to sell our products abroad. These events could result in increased costs, lower margins and lower demand than we have assumed in our projected financial results, which could have a material adverse effect on our business, financial condition, results of operations, or cash flows.

The market price of our common stock has been, and may continue to be, volatile.

The market price of our common stock has recently been, and may in the future be, volatile for various reasons, including those discussed in these risk factors. Other events that could cause volatility in our stock, include without limitation, variances in our financial results; analysts’ and other projections or recommendations regarding our common stock specifically or medical technology stocks generally; actions of activist shareholders; any restatement of our financial statements or any investigation of us by the SEC, the FDA, or another regulatory authority; or a decline, or rise, of stock prices in capital markets generally. In recent months, due in large part to the effect of the COVID-19 pandemic, domestic and international capital markets have experienced significant volatility and significant declines in those markets generally. The impact of the COVID-19 pandemic is likely to continue throughout 2020 and may amplify the effects of other events that could cause volatility in the market for our stock.

The agreements and instruments governing our debt contain restrictions and limitations that could significantly affect our ability to operate our business, as well as significantly affect our liquidity.

We have entered into a Third Amended and Restated Credit Agreement (the "Third Amended Credit Agreement"), with Wells Fargo Bank, National Association, as administrative agent and a lender, and Wells Fargo Securities, LLC, BOFA Securities, Inc., HSBC Bank USA, National Association, and U.S. Bank National Association as joint lead arrangers and joint bookrunners, and Bank of America, N.A., HSBC Bank USA, National Association and U.S. Bank National Association as co-syndication agents. In addition, Bank of America, N.A., HSBC Bank USA, National Association, U.S. Bank, National Association, BMO Harris Bank, N.A., and MUFG Union Bank, Ltd. are parties to the Third Amended Credit Agreement as lenders. The Third Amended Credit Agreement amends and restates in its entirety our previously outstanding Second Amended and Restated Credit Agreement and all amendments thereto. The Third Amended Credit Agreement contains a number of significant covenants that could adversely affect our ability to operate our business, our liquidity or our results of operations. These covenants restrict, among other things, our incurrence of indebtedness, creation of liens or pledges on our assets, mergers or similar combinations or liquidations, asset dispositions, repurchases or redemptions of equity interests or debt, issuances of equity, payment of dividends and certain distributions and entry into related party transactions.

We have pledged substantially all of our assets as collateral for the Third Amended Credit Agreement. Our breach of any covenant in the Third Amended Credit Agreement, not otherwise cured, waived or amended, could result in a default under that agreement and could trigger acceleration of the underlying obligations. Any default under the Third Amended Credit Agreement could adversely affect our ability to service our debt and to fund our planned capital expenditures and ongoing operations. The administrative agent, joint lead arrangers, joint bookrunners and lenders under the Third Amended Credit Agreement have available to them the remedies typically available to lenders and secured parties, including the ability to foreclose on the collateral we have pledged. It could lead to an acceleration of indebtedness and foreclosure on our assets.

As currently amended, the Third Amended Credit Agreement provides for potential borrowings of up to $750 million. Such increased borrowing limits may make it more difficult for us to comply with leverage ratios and other restrictive covenants in the Third Amended Credit Agreement. We may also have less cash available for operations and investments in our business, as we will be required to use additional cash to satisfy the minimum payment obligations associated with this increased indebtedness.

14.   Fair Value Measurements.

Assets (Liabilities) Measured at Fair Value on a Recurring Basis

Our financial assets and (liabilities) carried at fair value measured on a recurring basis as of March 31, 2020 and December 31, 2019, consisted of the following (in thousands):

			Fair Value Measurements Using
	Total Fair		Quoted prices in		Significant other		Significant

Contingent consideration liabilities	$	(76,709)	$	—	$	—	$	(76,709)

(1) The fair value of the interest rate contracts is determined using Level 2 fair value inputs and is recorded as other long-term assets or other long-term obligations 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 current assets or other long-term assets 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 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 or other milestones. See Note 4 for further information regarding these acquisitions. The contingent consideration liability is re-measured at the estimated fair value at the end of each reporting period with the change in fair value recognized within operating expenses in the accompanying consolidated statements of income (loss) for such period. We measure the initial liability and re-measure the liability on a recurring basis using Level 3 inputs as defined under authoritative guidance for fair value measurements.

Changes in the fair value of our contingent consideration liabilities during the three-month periods ended March 31, 2020 and 2019, consisted of the following (in thousands):

	Three Months Ended
	March 31,
	2020		2019
Beginning balance	$	76,709	$	82,236
Contingent consideration expense (1)		4,897		775
Contingent payments made		(12,754)		(554)
Effect of foreign exchange		17		—
Ending balance	$	68,869	$	82,457
(1) There were no fair value adjustments recorded to OCI for the three months ended March 31, 2020

As of March 31, 2020, approximately $57.6 million in contingent consideration liability was included in other long-term obligations and approximately $11.3 million in contingent consideration liability was included in accrued expenses in our consolidated balance sheet. As of December 31, 2019, approximately $48.1 million in contingent consideration liability was included in other long-term obligations and approximately $28.6 million in contingent consideration liability was included in accrued expenses in our consolidated balance sheet. Cash paid to settle the contingent consideration liability recognized at fair value as of the applicable acquisition date (including measurement-period adjustments) has been reflected as a cash outflow from financing activities in the accompanying consolidated statements of cash flows.

During the year ended December 31, 2016, we sold an equity investment for cash and for the right to receive additional payments based on various contingent milestones. We determined the fair value of the contingent payments using Level 3 inputs defined under authoritative guidance for fair value measurements, and we recorded a contingent receivable asset. During the three-month period ended March 31, 2019, we recorded a gain on the contingent receivable of approximately $20,000. As of December 31, 2019, the contingent receivable was settled in full and there was no balance remaining to collect.

The recurring Level 3 measurement of our contingent consideration liabilities included the following significant unobservable inputs at March 31, 2020 and December 31, 2019 (amounts in thousands):

	Fair value at
	March 31,		Valuation
Contingent consideration liability	2020		technique	Unobservable inputs	Range	Weighted Average(1)
Revenue-based royalty payments contingent liability	$	8,053	Discounted cash flow	Discount rate	12% - 24%	15.4%
				Projected year of payments	2020-2034	2026
Revenue milestones contingent liability	$	58,116	Monte Carlo simulation	Discount rate	9% - 14.5%	10.9%
				Projected year of payments	2020-2023	2022
Regulatory approval contingent liability	$	2,700	Scenario-based method	Discount rate	6.6%
				Probability of milestone payment	65%
				Projected year of payment	2022
(1) Unobservable inputs were weighted by the relative fair value of the instruments. No weighted average is reported for unobservable inputs related to a single financial asset or liability.

	Fair value at
	December 31,		Valuation
Contingent consideration liability	2019		technique	Unobservable inputs	Range
Revenue-based royalty payments contingent liability	$	7,710	Discounted cash flow	Discount rate	13% - 24%
				Projected year of payments	2020-2034
Revenue milestones contingent liability	$	66,114	Monte Carlo simulation	Discount rate	9% - 13.5%
				Projected year of payments	2020-2023
Regulatory approval contingent liability	$	2,885	Scenario-based method	Discount rate	2.4%
				Probability of milestone payment	65%
				Projected year of payment	2022

The contingent consideration liability is re-measured to fair value each reporting period. Significant increases or decreases in projected revenues, based on our most recent internal operational budgets and long-range strategic plans, discount rates or the time until payment is made would have resulted in a significantly lower or higher fair value measurement. Our determination of the fair value of the contingent consideration liability could change in future periods based upon our ongoing evaluation of these significant unobservable inputs. We intend to record any such change in fair value to operating expenses in our consolidated statements of income (loss).

Fair Value of Other Financial Instruments

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

We recognize or disclose the fair value of certain assets, such as non-financial assets, primarily property and equipment, intangible assets and goodwill in connection with impairment evaluations. All our nonrecurring valuations use significant unobservable inputs and therefore fall under Level 3 of the fair value hierarchy. During the three-month period ended March 31, 2020, we recorded impairment charges of approximately $359,000, related to certain property and equipment associated with our sale of the NvisionVLE® Imaging System under our distribution agreement with NinePoint Medical, Inc. (“NinePoint”). In addition, during the three-month periods ended March 31, 2020 and 2019, we had losses of approximately $81,000 and $211,000, respectively, related to the measurement of other non-financial assets at fair value on a nonrecurring basis subsequent to their initial recognition.

Our equity investments in privately held companies, including options to acquire these companies, were $14.5 million and $17.1 million at March 31, 2020 and December 31, 2019, respectively. We analyze our investments in privately-held companies to determine if they should be accounted for using the equity method based on our ability to exercise significant influence over operating and financial policies of the investment. Investments not accounted for under the equity method of accounting are accounted for at cost minus impairment, if applicable, plus or minus changes in valuation resulting from observable transactions for identical or similar investments. During the three-month period ended March 31, 2020 we recorded charges of $3.5 million due to our write-off of our purchase option to acquire Bluegrass Vascular due to our  decision not to exercise our option to purchase the business.

Our outstanding long-term notes receivable, including accrued interest, and in 2020 our allowance for current expected credit losses, were approximately $2.1 million and $2.7 million as of March 31, 2020 and December 31, 2019, respectively. As of March 31, 2020, we recognized an allowance for current expected credit losses of $670,000 associated with these notes receivable and our contractual obligation to extend credit to Selio. We assess the allowance for current expected credit losses on an individual security basis, due to the limited number of securities, using a probability of default model,

which is based on relevant information about past events, including historical experience, current conditions and reasonable and supportable forecasts that affect the expected collectability of securities. During the first quarter of 2020, we adjusted the probability of default for all securities for a period of one year due to changes in current macroeconomic conditions and our expectations of collectability.

The table below presents a rollforward for the period ended March 31, 2020 of the allowance for current expected credit losses on our notes receivable (in thousands):

Commitments and Contingencies

10.   Commitments and Contingencies.

Loan Commitment. On October 11, 2019, we acquired shares of stock in Selio Medical Limited (“Selio”) representing  an ownership interest of approximately 19.5%, as well as an option to purchase all ordinary shares of Selio throughout a 45 day period commencing from the date Selio receives FDA 510(k) approval of a medical device it is currently developing, and an option to purchase all remaining shares of Selio on the third anniversary date of the agreement if we elect to purchase all ordinary shares. We have also made a loan of $250,000 to Selio and committed to provide additional loans of up to  €2 million at a rate of 5% per annum. Additional loans made to Selio pursuant to our loan agreement, together with the initial advance and all other amounts owed to us by Selio, would be securitized by Selio’s assets.

Litigation: In the ordinary course of business, we are involved in various claims and litigation matters. These claims and litigation matters may include actions involving product liability, intellectual property, contract disputes, and employment or other matters that are significant to our business. For example, in December 2019 our company, our Chief Executive Officer and our Chief Financial Officer were named in a complaint filed in the Central District of California, which alleges violations of certain federal securities laws. Based upon our review of currently available information, we do not believe that any such actions are likely to be, individually or in the aggregate, materially adverse to our business, financial condition, results of operations or liquidity.

In addition to the foregoing matters, in October 2016, we received a subpoena from the U.S. Department of Justice seeking information on certain of our marketing and promotional practices. We have responded to the subpoena, as well as additional related requests. We have incurred, and anticipate that we will continue to incur, substantial costs in connection with the matter. The investigation is ongoing and at this stage we are unable to predict its scope, duration or outcome. Investigations such as this may result in the imposition of, among other things, significant damages, injunctions, fines, or civil or criminal claims or penalties against our company or individuals. Legal expenses we incurred in responding to the

U.S. Department of Justice investigation for the three-month periods ended March 31, 2020 and 2019 were approximately $1.5 million and $1.7 million, respectively.

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

Aggregate amortization expense for the three-month periods ended March 31, 2020 and 2019 was approximately $15.0 million and $14.8 million, respectively.

We evaluate long-lived assets, including amortizing intangible assets, for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. We perform the impairment analysis at the asset group for which the lowest level of identifiable cash flows is largely independent of the cash flows of other assets and liabilities. We compare the carrying value of the amortizing intangible assets acquired to the undiscounted cash flows expected to result from the asset group and determine whether the carrying amount is recoverable. We determine the fair value of our amortizing assets based on estimated future cash flows discounted back to their present value using a discount rate that reflects the risk profiles of the underlying activities. We did not identify indicators of impairment in any intangible assets based on our qualitative assessment for the three-month periods ended March 31, 2020 and 2019.

Estimated amortization expense for the developed technology and other intangible assets for the next five years consists of the following as of March 31, 2020 (in thousands):

Accounting Policies [Abstract]

Recently Issued Financial Accounting Standards

2.   Recently Issued Financial Accounting Standards.

Recently Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 became effective for us on January 1, 2020. The adoption of this standard did not have a material impact on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), which removes, modifies and adds various disclosure requirements related to fair value disclosures. ASU 2018-13 became effective for us beginning on January 1, 2020. We modified our disclosures beginning in the three-month period ended March 31, 2020 to conform with this guidance (see Note 14).

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaced the incurred loss impairment methodology for financial assets with a methodology that reflects expected credit losses. The new credit loss model must be applied to loans, accounts receivable, and other financial assets. ASU 2016-13 became effective for us beginning on January 1, 2020. We adopted this standard using a modified retrospective approach with a cumulative-effect adjustment to retained earnings of $575,000 as of the beginning of 2020. See Note 14 for additional disclosures related to our allowance for current expected credit losses. The adoption of this guidance did not have a material impact on our statements of operations or cash flows.

We currently believe that all other issued and not yet effective accounting standards are not relevant to our financial statements.

Income Taxes

Income Tax Disclosure [Abstract]

Income Taxes

7.   Income Taxes. Our provision for income taxes for the three-month periods ended March 31, 2020 and 2019 was a tax expense of approximately $1.2 million and $651,000, respectively, which resulted in an effective tax rate of

(58.3)% and 9.5%, respectively. The increase in the income tax expense and the corresponding change in the effective income tax rate for the three-month period ended March 31, 2020, when compared to the prior-year period, was primarily due to discrete expenses related to the fair value adjustment of the contingent consideration liabilities of recent equity acquisitions and the write-off of our purchase option to acquire Bluegrass Vascular Technologies, Inc. (“Bluegrass Vascular”) due to our decision not to exercise our option to purchase this business (see Note 14).

Revenue from Contract with Customer [Abstract]

Revenue from Contracts with Customers

3.   Revenue from Contracts with Customers. We recognize revenue when a customer obtains control of promised goods. The amount of revenue recognized reflects the consideration we expect to receive in exchange for these goods.

Disaggregation of Revenue

The disaggregation of revenue is based on product category and geographical region. Beginning in the first quarter of 2020, we revised our product categories to more clearly reflect how we sell our products to our customers. We presented historical information under the new revised product categories in a Current Report on Form 8-K, filed with the SEC on April 3, 2020.

We design, develop, manufacture and market 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 four product categories: peripheral intervention, cardiac intervention, custom procedural solutions, and OEM. Within these product categories, we sell a variety of products, including cardiology and radiology devices (which assist in diagnosing and treating coronary arterial disease, peripheral vascular disease and other non-vascular diseases), as well as embolotherapeutic, cardiac rhythm management, electrophysiology, critical care, breast cancer localization and guidance, biopsy, 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.

The following tables present revenue from contracts with customers for the three-month periods ended March 31, 2020 and 2019 (in thousands):

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

1.   Basis of Presentation. The interim consolidated financial statements of Merit Medical Systems, Inc. ("Merit," "we" or "us") for the three months ended March 31, 2020 and 2019 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, 2020 and December 31, 2019, and our results of operations and cash flows for the three-month periods ended March 31, 2020 and 2019. The results of operations for the three-month periods ended March 31, 2020 and 2019 are not necessarily indicative of the results for a full-year period. Within the financial statements and tables presented, certain columns and rows may not total due to the use of rounded numbers for disclosure purposes. Percentages and earnings per share amounts presented are calculated from the underlying amounts. These interim consolidated financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K (the "2019 Form 10-K") for the year ended December 31, 2019, which was filed with the Securities and Exchange Commission (the "SEC") on March 2, 2020.

Reclassifications

Certain reclassifications have been made to the 2019 periods to conform to the 2020 presentation. In the consolidated statements of cash flows, the fair value adjustment to contingent consideration is presented as a reconciling item between net income (loss) and cash flows from operating activities in 2020, with a corresponding reclassification of $775,000 made in the prior period for comparability, along with corresponding reclassifications to the change in certain operating assets and liabilities.

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivatives

9.   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. For qualifying hedges, the change in fair value is deferred in accumulated other comprehensive income, a component of stockholders’ equity in the accompanying consolidated balance sheets, and recognized in earnings at the same time the hedged item affects earnings. Changes in the fair value of derivatives not designated as hedging instruments are recorded in earnings throughout the term of the derivative.

Interest Rate Risk. 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 Third Amended Credit Agreement that is solely due to changes in the benchmark interest rate.

Derivative Instruments Designated as Cash Flow Hedges

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

On December 23, 2019, we entered into a pay-fixed, receive-variable interest rate swap with a notional amount of $75 million with Wells Fargo to fix the one-month LIBOR rate at 1.71% for the period from July 6, 2021 to July 31, 2024. 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 will reset, the swap will be settled with the counterparty, and interest will be paid.

At March 31, 2020 and December 31, 2019, our interest rate swaps qualified as cash flow hedges. The fair value of our interest rate swaps at March 31, 2020 was a liability of approximately $4.8 million, which was partially offset by approximately $1.2 million in deferred taxes. The fair value of our interest rate swaps at December 31, 2019 was an asset of approximately $1.2 million, partially offset by approximately $307,000 in deferred taxes, and a liability of $(290,000), partially offset by approximately $(75,000) 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 Chinese Renminbi, Euros, British Pounds, Mexican Pesos, Brazilian Reals, Australian Dollars, Hong Kong Dollars, Swiss Francs, Swedish Krona, Canadian Dollars, Danish Krone, Japanese Yen, and South Korean Won, among others. 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.

Derivative Instruments Designated as Cash Flow Hedges

For derivative instruments that are designated and qualify as cash flow hedges, the gain or loss on the derivative instrument is temporarily reported as a component of other comprehensive income (loss) and then 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. We entered 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 150 cash flow foreign currency hedges every month. As of March 31, 2020 and December 31, 2019 we had entered into foreign currency forward contracts, which qualified as cash flow hedges, with notional amounts of $173.2 million and $212.5 million, respectively.

Derivative Instruments Not Designated as Cash Flow Hedges

We forecast our net exposure in various receivables and payables to fluctuations in the value of various currencies, and we enter into foreign currency forward contracts to mitigate that exposure. We enter into approximately 20 foreign currency fair value hedges every month. As of March 31, 2020 and December 31, 2019 we had entered into foreign currency forward contracts related to those balance sheet accounts with notional amounts of $65.2 million and $65.0 million, respectively.

Balance Sheet Presentation of Derivative Instruments. As of March 31, 2020 and December 31, 2019, all derivative instruments, 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.

Organization, Consolidation and Presentation of Financial Statements [Abstract]

Basis of Presentation

1.   Basis of Presentation. The interim consolidated financial statements of Merit Medical Systems, Inc. ("Merit," "we" or "us") for the three months ended March 31, 2020 and 2019 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, 2020 and December 31, 2019, and our results of operations and cash flows for the three-month periods ended March 31, 2020 and 2019. The results of operations for the three-month periods ended March 31, 2020 and 2019 are not necessarily indicative of the results for a full-year period. Within the financial statements and tables presented, certain columns and rows may not total due to the use of rounded numbers for disclosure purposes. Percentages and earnings per share amounts presented are calculated from the underlying amounts. These interim consolidated financial statements should be read in conjunction with the financial statements included in our Annual Report on Form 10-K (the "2019 Form 10-K") for the year ended December 31, 2019, which was filed with the Securities and Exchange Commission (the "SEC") on March 2, 2020.

Recently Issued Financial Accounting Standards

Recently Adopted

In August 2018, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) 2018-15, Intangibles – Goodwill and Other – Internal-Use Software (Subtopic 350-40): Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract, which aligns the requirements for capitalizing implementation costs incurred in a hosting arrangement that is a service contract with the requirements for capitalizing implementation costs incurred to develop or obtain internal-use software (and hosting arrangements that include an internal-use software license). ASU 2018-15 became effective for us on January 1, 2020. The adoption of this standard did not have a material impact on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820), which removes, modifies and adds various disclosure requirements related to fair value disclosures. ASU 2018-13 became effective for us beginning on January 1, 2020. We modified our disclosures beginning in the three-month period ended March 31, 2020 to conform with this guidance (see Note 14).

In June 2016, the FASB issued ASU 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which replaced the incurred loss impairment methodology for financial assets with a methodology that reflects expected credit losses. The new credit loss model must be applied to loans, accounts receivable, and other financial assets. ASU 2016-13 became effective for us beginning on January 1, 2020. We adopted this standard using a modified retrospective approach with a cumulative-effect adjustment to retained earnings of $575,000 as of the beginning of 2020. See Note 14 for additional disclosures related to our allowance for current expected credit losses. The adoption of this guidance did not have a material impact on our statements of operations or cash flows.

We currently believe that all other issued and not yet effective accounting standards are not relevant to our financial statements.

Revenue Recognition

Revenue from Contracts with Customers. We recognize revenue when a customer obtains control of promised goods. The amount of revenue recognized reflects the consideration we expect to receive in exchange for these goods.

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. For qualifying hedges, the change in fair value is deferred in accumulated other comprehensive income, a component of stockholders’ equity in the accompanying consolidated balance sheets, and recognized in earnings at the same time the hedged item affects earnings. Changes in the fair value of derivatives not designated as hedging instruments are recorded in earnings throughout the term of the derivative.

Interest Rate Risk. 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 Third Amended Credit Agreement that is solely due to changes in the benchmark interest rate.

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 Chinese Renminbi, Euros, British Pounds, Mexican Pesos, Brazilian Reals, Australian Dollars, Hong Kong Dollars, Swiss Francs, Swedish Krona, Canadian Dollars, Danish Krone, Japanese Yen, and South Korean Won, among others. 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.

Derivative Instruments Designated as Cash Flow Hedges

For derivative instruments that are designated and qualify as cash flow hedges, the gain or loss on the derivative instrument is temporarily reported as a component of other comprehensive income (loss) and then 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. We entered 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.

Derivative Instruments Not Designated as Cash Flow Hedges

We forecast our net exposure in various receivables and payables to fluctuations in the value of various currencies, and we enter into foreign currency forward contracts to mitigate that exposure.

Balance Sheet Presentation of Derivative Instruments. As of March 31, 2020 and December 31, 2019, all derivative instruments, 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.

Segment Reporting [Abstract]

Segment Reporting

13.   Segment Reporting. We report our operations in two operating segments: cardiovascular and endoscopy. Our cardiovascular segment consists of four product categories: peripheral intervention, cardiac intervention, custom procedural solutions, and OEM. Within these product categories, we sell a variety of products, including cardiology and radiology devices (which assist in diagnosing and treating coronary arterial disease, peripheral vascular disease and other non-vascular diseases), as well as embolotherapeutic, cardiac rhythm management, electrophysiology, critical care, breast cancer localization and guidance, biopsy, 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. We evaluate the performance of our operating segments based on net sales and operating income.

Financial information relating to our reportable operating segments and reconciliations to the consolidated totals for the three-month periods ended March 31, 2020 and 2019, were as follows (in thousands):

16. Subsequent Events.

COVID-19 Pandemic

In December 2019, a novel strain of coronavirus (“COVID-19”) surfaced in Wuhan, China. In March 2020, the World Health Organization classified the COVID-19 outbreak as a pandemic, and the virus has spread to most countries and to all 50 states within the United States. The COVID-19 pandemic has created significant uncertainty in the global economy, has negatively impacted our business, results of operations and financial condition, and we anticipate that it may negatively impact our business, results of operations and financial condition for the foreseeable future. At present, it is not possible for us to predict the extent of this impact due to uncertainties regarding the duration of the pandemic, potential government mandates regarding elective procedures, and patient behavior, among other factors.

In response to the COVID-19 pandemic, we implemented certain cost reduction and operating efficiency initiatives, including decreased discretionary spending, delayed product launches, and deferred capital spending and research and development projects, among other initiatives. In April 2020, due to the significant impact of the COVID-19 pandemic on our business, results of operations and financial condition, and uncertainly regarding the scope and duration of that impact, we implemented furloughs and a temporary salary reduction for executive management and certain other salaried personnel. We also implemented processes to encourage the safety of our employees, including formal policies restricting travel, temperature screenings at most of our manufacturing locations, and mandatory telecommuting for certain positions.

As the impact of the COVID-19 pandemic evolves, we will continue to assess the impact on our business and respond accordingly. Sustained adverse impacts to our business, our suppliers, and our customers may also affect our future valuation of certain assets and therefore may increase the likelihood of an impairment charge, write-off, or reserve associated with such assets, including goodwill, finite-lived intangible assets, property and equipment, inventories, accounts receivable, tax assets, and other assets. Estimates may change as new events occur and additional information is obtained, and actual results will likely differ, and may differ materially, from our estimates under different assumptions, circumstances or conditions.

We use the Black-Scholes methodology to value the stock-based compensation expense for options. In applying the Black-Scholes methodology to the option grants, the fair value of our stock-based awards granted was estimated using the following assumptions for the periods indicated below:

	Three Months Ended
	March 31,
	2020	2019
Risk-free interest rate	0.52% - 1.67%	2.42% - 2.56%
Expected option term	4.0 - 5.0 years	3.0 - 5.0 years
Expected dividend yield	—	—
Expected price volatility	38.65% - 43.24%	28.93% - 33.69%

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 award. 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 term and implied volatility based on recent trends of the daily historical volatility. For awards with a vesting period, compensation expense is recognized on a straight-line basis over the service period, which corresponds to the vesting period.

We recognize stock-based compensation expense (net of a forfeiture rate) for those awards which are expected to vest on a straight-line basis over the requisite service period. We estimate the forfeiture rate based on our historical experience and expectations about future forfeitures. As of March 31, 2020, the total remaining unrecognized compensation cost related to non-vested stock options was approximately $28.4 million, which was expected to be recognized over a weighted average period of 2.93 years.

Stock-Settled Performance-Based Restricted Stock Units

During the three-month period ended March 31, 2020, we granted stock-settled performance-based restricted stock units (“performance stock units”) to certain of our executive officers representing up to 152,475 shares of our common stock. Conversion of the performance stock units occurs at the end of one, two and three-year performance periods, or one year after the agreement date, whichever is later. The conversion ratio is based upon attaining targeted levels of free cash flow (“FCF”) and relative shareholder return as compared to the Russell 2,000 (“rTSR”), as defined in the award agreements. The payout for each unit is equal to one share of common stock multiplied by a FCF multiplier (between 0% and 200%) and a rTSR multiplier (between 75% and 125%). If FCF is below a specified threshold, no shares will be awarded. The potential maximum payout per performance stock units is 250% of the target shares. Performance stock units convey no shareholder rights, including voting rights, unless and until shares are issued in settlement of the award. As performance stock units represent contingently issuable shares, we have excluded them from the calculation of weighted average shares outstanding for the calculation of diluted EPS.

We use Monte-Carlo simulations to estimate the grant-date fair value of the performance stock units linked to total shareholder return. The fair value of each performance stock unit was estimated using the following assumptions for the periods indicated below:

	Three Months Ended
	March 31,
	2020
Risk-free interest rate	1.1% - 1.3%
Performance period	0.8 - 2.8 years
Expected dividend yield	—
Expected price volatility	40.2% - 56.1%

The risk-free interest rate of return was determined using the U.S. Treasury rate at the time of grant with a remaining term equal to the expected term of the award. The expected volatility was based on a weighted average volatility of our stock price and the average volatility of our compensation peer group's volatilities. The expected dividend yield was assumed to be zero because, at the time of the grant, we had no plans to declare a dividend.

Compensation expense is recognized using the grant-date fair value for the number of shares that are probable of being awarded based on the performance conditions. Each reporting period, this probability assessment is updated, and cumulative catchups are recorded based on the level of FCF that is expected to be achieved. At the end of the performance period, cumulative expense is calculated based on the final number of shares awarded. For the three-month period ended March 31, 2020, we recognized stock-based compensation expense associated with the performance stock units of approximately $0.3 million. As of March 31, 2020, the total remaining unrecognized compensation cost related to performance stock units was approximately $5.0 million, which is expected to be recognized over a weighted average period of 1.83 years.

Cash-Settled Performance-Based Share-Based Awards

During the three-month period ended March 31, 2020, we granted cash-settled performance-based share-based awards to our Chief Executive Officer. These awards entitle him to a cash payment equal to a target cash incentive multiplied by rTSR and FCF multipliers, as defined in the award agreements. The potential maximum payout is 250% of the target cash incentive. Settlement generally occurs at the end of one, two and three-year performance periods based upon the same performance metrics and vesting period as our performance stock units.

For the three-month period ended March 31, 2020, we recognized expense associated with these cash-settled performance-based restricted stock units of approximate $0.1 million within selling, general and administrative expenses in our consolidated statement of income (loss). The fair value of these awards will be remeasured at each reporting period until the awards are settled. These awards are classified as liabilities and reported in accrued expenses and other long-term assets within our consolidated balance sheet. As of March 31, 2020, the total remaining unrecognized compensation cost related to cash-settled performance-based share-based awards was approximately $2.2 million, which is expected to be recognized over a weighted average period of 1.83 years.

Third Amended and Restated Credit Agreement

On July 31, 2019, we entered into a Third Amended and Restated Credit Agreement (the "Third Amended Credit Agreement"). The Third Amended Credit Agreement is a syndicated loan agreement with Wells Fargo Bank, National Association and other parties. The Third Amended Credit Agreement amends and restates in its entirety our previously outstanding Second Amended and Restated Credit Agreement and all amendments thereto. The Third Amended Credit Agreement provides for a term loan of $150 million and a revolving credit commitment up to an aggregate amount of $600 million, inclusive of sub-facilities for multicurrency borrowings, standby letters of credit and swingline loans. On July 31, 2024, all principal, interest and other amounts outstanding under the Third Amended Credit Agreement are payable in full. At any time prior to the maturity date, we may repay any amounts owing under all term loans and revolving credit loans in whole or in part, without premium or penalty, other than breakage fees (as defined in the Third Amended Credit Agreement).

Revolving credit loans denominated in dollars and term loans made under the Third Amended Credit Agreement bear interest, at our election, at either the Base Rate or the Eurocurrency Rate (as such terms are defined in the Third Amended Credit Agreement) plus the Applicable Margin (as defined in the Third Amended Credit Agreement). Revolving credit loans denominated in an Alternative Currency (as defined in the Third 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 (as defined in the Third Amended Credit Agreement). Interest on each loan featuring the Base Rate is due and payable on the last business day of each calendar quarter; interest on each loan featuring the Eurocurrency Rate is due and payable on the last day of each interest period applicable thereto, and if such interest period extends over three months, at the end of each three-month interval during such interest period.

The Third Amended Credit Agreement is collateralized by substantially all our assets. The Third Amended Credit Agreement contains affirmative and negative covenants, representations and warranties, events of default and other terms

customary for loans of this nature. In particular, the Third Amended Credit Agreement requires that we maintain certain financial covenants, as follows:

	Covenant Requirement
Consolidated Total Leverage Ratio (1)		4.0 to 1.0
Consolidated Interest Coverage Ratio (2)		3.0 to 1.0
Facility Capital Expenditures (3)		$50 million

(1) Maximum Consolidated Total Net Leverage Ratio (as defined in the Third Amended Credit Agreement) as of any fiscal quarter end.

(2) Minimum ratio of Consolidated EBITDA (as defined in the Third Amended Credit Agreement and adjusted for certain expenditures) to Consolidated interest expense (as defined in the Third Amended Credit Agreement) for any period of four consecutive fiscal quarters.

(3) Maximum level of the aggregate amount of all Facility Capital Expenditures (as defined in the Third Amended Credit Agreement) in any fiscal year.

As of March 31, 2020, we believe we were in compliance with all covenants set forth in the Third Amended Credit Agreement.

As of March 31, 2020, we had outstanding borrowings of approximately $446.1 million under the Third Amended Credit Agreement, with additional available borrowings of approximately $232.1 million, based on the net leverage ratio required pursuant to the Third Amended Credit Agreement. Our interest rate as of March 31, 2020 was a fixed rate of 2.87% on $175 million as a result of an interest rate swap (see Note 9) and a variable floating rate of 2.74% on $271.1 million. Our interest rate as of December 31, 2019 was a fixed rate of 2.62% on $175 million as a result of an interest rate swap and a variable floating rate of 3.30% on $265 million.

Future minimum principal payments on our long-term debt as of March 31, 2020, were as follows (in thousands):

Business Combinations [Abstract]

Acquisitions

4.   Acquisitions. On August 1, 2019, we entered into a share purchase agreement to acquire Fibrovein Holdings Limited, which is the owner of 100% of the capital stock of STD Pharmaceutical Products Limited, a UK private company engaged in the manufacture, distribution and sale of pharmaceutical sclerotherapy products (“STD Pharmaceutical”). The purchase consideration consisted of an upfront payment of approximately $13.7 million, net of cash acquired. We also recorded a contingent consideration liability of approximately $934,000 related to royalties potentially payable pursuant to the terms of the share purchase agreement. We accounted for this acquisition as a business combination. 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 STD Pharmaceutical acquisition, which were included in selling, general and administrative expenses, were not material. The purchase price was preliminarily allocated as follows (in thousands):

Assets Acquired
Trade receivables	$	277
Inventories		843
Prepaid expenses and other assets		49
Intangible assets
Developed technology		10,428
Goodwill		4,975
Total assets acquired		16,572
Liabilities Assumed
Trade payables		(53)
Accrued expenses		(29)
Deferred income tax liabilities		(1,890)
Total liabilities assumed		(1,972)
Total net assets acquired	$	14,600

We are amortizing the developed technology intangible asset acquired in the STD Pharmaceutical acquisition over 12 years. The goodwill consists largely of the synergies we hope to achieve from combining operations and is not expected to be deductible for income tax purposes.

On June 14, 2019, we consummated an acquisition transaction contemplated by a merger agreement to acquire Brightwater Medical, Inc. ("Brightwater"). The purchase consideration consisted of an upfront payment of $35 million plus a final working capital adjustment of approximately $39,000, net of cash acquired, with potential earn-out payments of up to an additional $5 million for achievement of CE certification with respect to the Brightwater ConvertX®, a single-use device used to replace a series of devices and procedures used to treat severe obstructions of the ureter, and up to an additional $10 million for the achievement of sales milestones specified in the merger agreement. The ConvertX device is designed to be implanted once and converted from a nephroureteral catheter to a nephroureteral stent without requiring sedation or local anesthesia. Brightwater recently received FDA clearance for the ConvertX biliary stent device. We accounted for this acquisition as a business combination. 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 Brightwater acquisition, which were included in selling, general and administrative expenses, were not material. The purchase price was preliminarily allocated as follows (in thousands):

Assets Acquired
Trade receivables	$	55
Inventories		349
Property and equipment		409
Other long-term assets		30
Intangible assets
Developed technology		31,960
Customer lists		83
Trademarks		250
Goodwill		17,492
Total assets acquired		50,628
Liabilities Assumed
Trade payables		(58)
Accrued expenses		(261)
Other long-term obligations		(1,522)
Deferred income tax liabilities		(4,148)
Total liabilities assumed		(5,989)
Total net assets acquired	$	44,639

We are amortizing the developed technology intangible asset acquired in the Brightwater acquisition over 13 years, the related trademarks over five years and the customer list on an accelerated basis over one year. The total weighted-average amortization period for these acquired intangible assets is approximately 12.9 years. The goodwill consists largely of the synergies and economies of scale we hope to achieve from combining the acquired assets and operations with our historical operations and is not expected to be deductible for income tax purposes.

The pro forma impact of these acquisitions was not significant, either individually or in the aggregate, on our financial results for the three-month period ended March 31, 2019. Operating results attributable to the STD Pharmaceutical and Brightwater acquisitions were included in our consolidated statements of income (loss) for the three-month period ended March 31, 2020.
