1. Business Overview

Company Description

Cardiovascular Systems, Inc. (the “Company”) develops, manufactures and markets devices for the treatment of vascular diseases. The Company’s peripheral arterial disease (“PAD”) products, the Diamondback 360^® Peripheral Orbital Atherectomy System (“OAS”) and the Stealth 360°^® Peripheral OAS, are catheter-based platforms capable of treating a broad range of plaque types, including calcified plaque, in leg arteries both above and below the knee, and these products address many of the limitations associated with other surgical, catheter and pharmacological treatment alternatives. These devices use smaller access sheaths that can provide procedural benefits and allow physicians to treat PAD patients in a variety of vessel sizes, including the small and tortuous vessels located below the knee, and facilitate access through alternative sites in the ankle, foot and wrist, as well as in the groin.

In October 2013, the Company received premarket approval from the United States Food and Drug Administration (“FDA”) to market the Diamondback 360 Coronary OAS (the “Coronary OAS”) as a treatment for severely calcified coronary arteries. In March 2017, the Company received approval from the FDA to market the Diamondback 360 Coronary OAS Micro Crown (the “Coronary OAS Micro Crown”). The Coronary OAS Micro Crown is the only atherectomy device designed to both pilot tight, calcific lesions and treat 2.5 to 4 mm vessels with a single device.

Until February 2018, the Company sold its products only in the United States. In November 2016, the Company signed an exclusive distribution agreement with Medikit Co., Ltd. (“Medikit”) to sell its Coronary and Peripheral OAS in Japan. In March 2017, the Company received approval from Japan’s Ministry of Health, Labor and Welfare for its Coronary OAS Micro Crown. On February 1, 2018, the Coronary OAS Micro Crown received reimbursement approval in Japan, followed by the first commercial sales, making Japan the first international market for any of the Company’s products. The Company is currently evaluating options for additional international markets to expand the coronary and peripheral opportunities.

2. Summary of Significant Accounting Policies

Interim Financial Statements

The Company prepared the unaudited interim consolidated financial statements and related unaudited financial information in the footnotes in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and the rules and regulations of the Securities and Exchange Commission (“SEC”) for interim financial statements. The year-end consolidated balance sheet was derived from the Company’s audited consolidated financial statements, but does not include all disclosures as required by GAAP. These interim consolidated financial statements reflect all adjustments consisting of normal recurring accruals, which, in the opinion of management, are necessary for a fair statement of the Company’s consolidated financial position, the results of its operations and its cash flows for the interim periods. These interim consolidated financial statements should be read in conjunction with the consolidated annual financial statements and the notes thereto included in the Annual Report on Form 10-K filed by the Company with the SEC on August 24, 2017. The nature of the Company’s business is such that the results of any interim period may not be indicative of the results to be expected for the entire year.

Use of Estimates

The preparation of the Company’s consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Table of Contents

Stock-Based Compensation

The Company has stock-based compensation plans, which include stock options, nonvested share awards, and an employee stock purchase plan. Fair value of option awards is determined using option-pricing models, fair value of nonvested share awards with market conditions is determined using the Monte Carlo simulation, and fair value of nonvested share awards that vest based upon service conditions is determined by the closing market price of the Company’s stock on the date of grant. Stock-based compensation expense is recognized ratably over the requisite service period for the awards expected to vest.

Revenue Recognition

The Company sells the majority of its products via direct shipment to hospitals or clinics. The Company recognizes revenue when all of the following criteria are met: persuasive evidence of an arrangement exists; delivery has occurred; the sales price is fixed or determinable; and collectability is reasonably assured. Revenue recognition may occur upon shipment or upon delivery to the customer site, based on the contract terms. The Company records estimated sales returns, discounts and rebates as a reduction of net sales.

Deferred revenue associated with the upfront payment received under the Company’s Japan distribution agreement (see Note 3 for additional details) will be recognized in relation to the estimated future sales under the agreement. The short term portion represents the expected amount of deferred revenue that will be recognized over the next year. The estimate of future sales under contract will continue to be assessed and adjusted accordingly.

Costs related to products delivered are recognized in the period revenue is recognized. Cost of goods sold consists primarily of raw materials, direct labor, and manufacturing overhead.

Recent Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board (“FASB”) issued amended revenue recognition guidance to clarify the principles for recognizing revenue from contracts with customers. The guidance requires an entity to recognize revenue in an amount that reflects the consideration to which an entity expects to be entitled in exchange for the transfer of goods or services. The guidance also requires expanded disclosures relating to the nature, amount, timing, and uncertainty of revenue and cash flows arising from contracts with customers. Additionally, qualitative and quantitative disclosures are required about customer contracts, significant judgments and changes in judgments, and assets recognized from the costs to obtain or fulfill a contract. The Company is currently in the process of analyzing the impact of the new standard, which includes reviewing customer contracts, applying the five-step model of the new standard to the customer contracts and comparing the results to the Company’s current accounting. The Company is also evaluating the method of adoption and assessing changes that might be necessary to information technology systems, processes, and internal controls to capture new data and address changes in financial reporting. Effective July 1, 2018, the Company will be revising its revenue recognition accounting policy and expanding revenue disclosures to reflect the requirements of the amended revenue recognition guidance. Because of the nature of the work that remains, at this time the Company is unable to reasonably estimate the impact of adoption on its consolidated financial statements.

In January 2016, the FASB issued ASU 2016-01, “Recognition and Measurement of Financial Assets and Financial Liabilities,” which revises the accounting requirements related to the classification and measurement of investments in equity securities and the presentation of certain fair value changes for financial liabilities measured at fair value. The update also changes certain disclosure requirements associated with the fair value of financial instruments. These changes will require an entity to measure, at fair value, investments in equity securities and recognize the changes in fair value within net income. ASU 2016-01 will be applied on a modified retrospective basis to all outstanding instruments, with an adjustment recorded to opening retained earnings as of the beginning of the first period in which the guidance becomes effective. The guidance is effective for annual periods beginning after December 15, 2017, including interim periods within those fiscal years, with early adoption permitted. The guidance is effective for the Company on July 1, 2018. The Company does not anticipate a material impact on its financial statements upon adoption.

In February 2016, the FASB issued ASU 2016-02, “Leases.” The guidance requires lessees to recognize the assets and liabilities that arise from leases on the balance sheet. ASU 2016-02 is effective for annual periods beginning after December 15, 2018, including interim periods within those annual periods, and should be applied using a modified retrospective approach. Early adoption is permitted. The guidance is effective for the Company on July 1, 2019. The Company is currently evaluating the timing, method of adoption and impact of the new lease guidance on its financial statements.

Table of Contents

In June 2016, the FASB issued ASU No. 2016-13, “Measurement of Credit Losses on Financial Instruments,” which revises guidance for the accounting for credit losses on financial instruments within its scope. The new standard introduces an approach, based on expected losses, to estimate credit losses on certain types of financial instruments and modifies the impairment model for available-for-sale debt securities. The new approach to estimating credit losses (referred to as the current expected credit losses model) applies to most financial assets measured at amortized cost and certain other instruments, including trade and other receivables, loans, held-to-maturity debt securities, net investments in leases and off-balance-sheet credit exposures. ASU 2016-13 is effective for annual periods beginning after December 15, 2019, including interim periods within those fiscal years. Early adoption is permitted and should be applied as a cumulative-effect adjustment to retained earnings as of the beginning of the first reporting period in which the guidance is adopted. The guidance is effective for the Company on July 1, 2020. The Company does not anticipate a material impact on its financial statements upon adoption.

In May 2017, the FASB issued ASU 2017-09, “Scope of Modification Accounting,” which clarifies when changes to the terms or conditions of a share-based payment award must be accounted for as modifications. The new guidance will reduce diversity in practice and result in fewer changes to the terms of an award being accounted for as modifications. ASU 2017-09 will be applied prospectively to awards modified on or after the adoption date. The guidance is effective for annual periods, and interim periods within those annual periods beginning after December 15, 2017, with early adoption permitted. The guidance is effective for the Company on July 1, 2018. The Company does not anticipate a material impact on its financial statements upon adoption.

In December, 2016, the Company entered into a Purchase and Sale Agreement, as subsequently amended (collectively, the “Sale Agreement”), with Krishna Holdings, LLC (“Krishna”), providing for the sale to Krishna of the Company’s headquarters facility in St. Paul, Minnesota (the “Facility”) for a cash purchase price of $21,500. On March 30, 2017, the sale of the Facility under the Sale Agreement closed. The Company received proceeds of approximately $20,944 ($21,500, less $556 of transaction expenses). The net proceeds are to be used for working capital and general corporate purposes.

Under the Sale Agreement, the Company entered into a Lease Agreement (the “Lease Agreement”) with Krishna Holdings, LLC, Apex Holdings, LLC, Kashi Associates, LLC, Keva Holdings, LLC, S&V Ventures, LLC, Polo Group LLC, SPAV Holdings LLC, Star Associates LLC, and The Global Villa, LLC. As the lease terms resulted in a capital lease classification, the Company accounted for the sale and leaseback of the Facility as a financing transaction where the assets remain on the Company’s balance sheet.

Under the Settlement Agreement, the Company agreed to pay $8,000 (the “Settlement Amount”), as follows: an initial payment of $3,000, paid on July 1, 2016, with the remaining $5,000, which bears interest at 1.8% per annum, payable in 11 equal quarterly installments, beginning January 1, 2017. The amount payable within the next twelve months is included in accrued expenses (as noted in the table above) with the long-term portion included in other liabilities (as noted in the table below). Under the Settlement Agreement, if the Company makes a single payment in excess of $2,000, which payment is not covered by an insurance policy, in settlement of any claims before

Deferred Revenue

In November 2016, the Company signed an exclusive distribution agreement with Medikit to sell its Diamondback 360^®Coronary and Peripheral OAS in Japan. To secure exclusive distribution rights, Medikit made an upfront payment of $10,000 to the Company, which is refundable based on performance under the terms of the agreement. On February 1, 2018, the Coronary OAS Micro Crown received reimbursement approval in Japan, followed by the first commercial sales. Accordingly, the Company has classified $1,095 of the upfront payment as current and $8,905 as long-term based on its expected amount of deferred revenue that will be recognized over the next year. The estimate will be assessed and adjusted accordingly on a quarterly basis.

4. Debt

Revolving Credit Facility

In March 2017, the Company entered into a Loan and Security Agreement (the “Loan Agreement”) with Silicon Valley Bank (“SVB”). The Loan Agreement provides for a senior, secured revolving credit facility (the “Revolver”) of $40,000 (the “Maximum Dollar Amount”).

Advances under the Revolver may be made from time to time up to the Maximum Dollar Amount, subject to certain borrowing limitations. The Revolver has a maturity date of March 31, 2020 and bears interest at a floating per annum rate equal to the Wall Street Journal prime rate, less 0.25%. Interest on borrowings is due monthly and the principal balance is due at maturity. Borrowings up to $10,000 are available on a non-formula basis. Borrowings above $10,000 are based on (i) 85% of eligible domestic accounts receivable, and (ii) the lesser of 50% of eligible inventory or $5,000, subject to adjustment as defined in Loan Agreement. Upon the Revolver’s maturity, any outstanding principal balance, unpaid accrued interest, and all other obligations under the Revolver will be due and payable. The Company will incur a fee equal to 1% of the Maximum Dollar Amount upon termination of the Loan Agreement or the Revolver for any reason prior to the maturity date, unless refinanced with SVB.

The Company’s obligations under the Loan Agreement are secured by certain of the Company’s assets, including, among other things, accounts receivable, deposit accounts, inventory, equipment, general intangibles and records pertaining to the foregoing. The collateral does not include the Company’s intellectual property, but the Company has agreed not to encumber its intellectual property without the consent of SVB. The Loan Agreement contains customary covenants limiting the Company’s ability to, among other things, incur debt or liens, make certain investments and loans, enter into transactions with affiliates, undergo certain fundamental changes, dispose of assets, or change the nature of its business. In addition, the Loan Agreement contains financial covenants requiring the Company to maintain, at all times when any amounts are outstanding under the Revolver, either (i) minimum unrestricted cash at SVB and unused availability on the Revolver of at least $10,000 or (ii) minimum trailing three-month Adjusted EBITDA of $1,000. If the Company does not comply with the various covenants under the Loan Agreement, the interest rate on outstanding amounts will increase by 5% and SVB may, subject to various customary cure rights, decline to provide additional advances under the Revolver, require the immediate payment of all amounts outstanding under the Revolver, and foreclose on all collateral.

Table of Contents

Under the Loan Agreement, the Company paid SVB a non-refundable commitment fee of $80, which will be amortized to interest expense over the term of the Loan Agreement. The Company is required to pay a fee equal to 0.35% per annum on the unused portion of the Revolver, payable quarterly in arrears. The Company is not obligated to draw any funds under the Revolver and has not done so under the Revolver since entering into the Loan Agreement. No amounts are outstanding as of December 31, 2017.

Financing Obligation

In connection with the sale of the Facility, the Company entered into an agreement to lease the Facility. The Lease Agreement has an initial term of fifteen years, with four consecutive renewal options of five years each at the Company’s option, with a base annual rent in the first year of $1,638 and annual escalations of 3% thereafter. Rent during subsequent renewal terms will be at the then fair market rental rate. As the lease terms resulted in a capital lease classification, the Company accounted for the sale and leaseback of the Facility as a financing transaction where the assets remain on the Company’s balance sheet and a financing obligation was recorded for $20,944. As lease payments are made, they will be allocated between interest expense and a reduction of the financing obligation, resulting in a value of the financing obligation that is equivalent to the net book value of the assets at the end of the lease term. The effective interest rate is 7.89%. At the end of the lease (including any renewal option terms), the Company will remove the assets and financing obligation from its balance sheet.

Payments under the initial term of the Lease Agreement as of December 31, 2017 are as follows:



Six months ended June 30, 2018	$	831
Fiscal 2019	1,699
Fiscal 2020	1,750
Fiscal 2021	1,803
Fiscal 2022	1,857
Thereafter	21,288
	$	29,228

5. Deferred Compensation Plan

The Company offers certain members of management and highly compensated employees the opportunity to defer up to 100% of their base salary (after 401(k), payroll tax and other deductions), performance bonus and discretionary bonus and elect to receive the deferred compensation at a fixed future date of participant’s choosing. Each participant may, at the time of his or her deferral election, choose to allocate the deferred compensation into investment alternatives set by the Human Resources and Compensation Committee. The amount payable to each participant under the plan will change in value based upon the investment selected by that participant and is classified as current or long-term on the Company’s balance sheet based on the disbursement elections made by the participants. As of December 31, 2017, $196 of the amount payable is included in accrued liabilities and $440 is included in other liabilities on the consolidated balance sheet.

The available-for-sale marketable securities are comprised of individual mutual funds which invest in fixed income and equity securities and consist of the following:



	As of December 31, 2017
	Amortized Cost		Unrealized Gains		Unrealized Losses		Fair Value
Mutual funds	$	524	$	112	$	—	$	636
Total short-term investments	$	524	$	112	$	—	$	636

Total short-term investments	$	604	$	100	$	—	$	704

Table of Contents

During the three and six months ended December 31, 2017 and 2016, there were no purchases of available-for-sale securities or other-than-temporary impairments. There was $49 and $96 of available-for-sale securities that were sold during the three and six months ended December 31, 2017, respectively. There were no sales during the three and six months ended December 31, 2016. During the three and six months ended December 31, 2017, there was a realized gain of $8 and $16, respectively, that was recorded within interest and other, net on the consolidated statement of operations.

The following table provides information by level for the Company’s available-for-sale marketable securities that were measured at fair value on a recurring basis:



			Fair Value Measurements as of December 31, 2017 Using Inputs Considered as
	Fair Value		Level 1		Level 2		Level 3
Mutual funds	$	636	$	252	$	384	$	—

Mutual funds	$	704	$	281	$	423	$	—
Total short-term investments	$	704	$	281	$	423	$	—

The Company’s marketable securities classified within Level 1 are valued using real-time quotes for transactions in active exchange markets. Marketable securities within Level 2 are valued using readily available pricing sources. There were no transfers of assets between Level 1 and Level 2 of the fair value measurement hierarchy during the six months ended December 31, 2017. Any transfers between levels would be recognized on the date of the event or when a change in circumstances causes a transfer.

6. Stock Options and Restricted Stock Awards

On November 15, 2017, the Company’s stockholders approved the 2017 Equity Incentive Plan (the “2017 Plan”), for the purpose of granting equity awards to employees, directors and consultants. The 2017 Plan replaced the 2014 Equity Incentive Plan (the “2014 Plan”), and no further equity awards may be granted under the 2014 Plan or the 2007 Equity Incentive Plan (the “2007 Plan”) (the 2017 Plan, 2014 Plan and the 2007 Plan are collectively referred to as the “Plans”).

Stock Options

All options granted under the Plans become exercisable over periods established at the date of grant. The option exercise price is generally not less than the estimated fair market value of the Company’s common stock at the date of grant, as determined by the Company’s management and Board of Directors. An employee’s vested options must be exercised at or within 90 days of termination to avoid forfeiture. As of December 31, 2017, all outstanding options were fully vested.

Stock option activity for the six months ended December 31, 2017 is as follows:



	Number of Options^(a)		Weighted Average Exercise Price
Options outstanding at June 30, 2017	78,201		$	9.07
Options exercised	(55,880	)	$	9.20
Options outstanding at December 31, 2017	22,321		$	8.75
(a) Includes the effect of options granted, exercised, forfeited or expired from the 2007 Plan.

Table of Contents

Restricted Stock

The value of each restricted stock award is equal to the fair market value of the Company’s common stock at the date of grant. Vesting of time-based restricted stock awards ranges from one to three years. The estimated fair value of restricted stock awards, including the effect of estimated forfeitures, is recognized on a straight-line basis over the restricted stock’s vesting period.

Restricted stock award activity for the six months ended December 31, 2017 is as follows:



	Number of Shares		Weighted Average Fair Value
Outstanding at June 30, 2017	486,584		$	21.26
Granted	209,796		$	29.64
Forfeited	(39,545	)	$	21.46
Vested	(197,052	)	$	22.74
Outstanding at December 31, 2017	459,783		$	24.43

Performance-Based Restricted Stock

The Company also grants performance-based restricted stock awards to certain executives and other management. In August and November 2017, the Company granted an aggregate maximum of 251,479 and 27,140 shares, respectively, that vest based on the Company’s total shareholder return relative to total shareholder return of the Company’s peer group (a market condition), as measured by the closing prices of the stock of the Company and the peer group members for the 90 trading days preceding July 1, 2017 compared to the closing prices of the stock of the Company and the peer group members for the 90 trading days preceding July 1, 2020. Vesting of these awards will be determined on the date that the Company’s Annual Report on Form 10-K for the fiscal year ending June 30, 2020 is filed.

To calculate the estimated fair value of these restricted stock awards with market conditions, the Company uses a Monte Carlo simulation, which uses the expected average stock prices to estimate the expected number of shares that will vest. The Monte Carlo simulation resulted in an aggregate fair value of approximately $3,801, which the Company will recognize as expense using the straight-line method over the period that the awards are expected to vest. Stock-based compensation expense related to an award with a market condition will be recognized regardless of whether the market condition is satisfied, provided that the requisite service has been provided.

Performance-based restricted stock awards granted in August 2016 that are outstanding vest based on the Company’s total shareholder return relative to total shareholder return of the Company’s peer group (a market condition), as measured by the closing prices of the stock of the Company and the peer group members for the 90 trading days preceding July 1, 2016 compared to the closing prices of the stock of the Company and the peer group members for the 90 trading days preceding July 1, 2019.

Performance-based restricted stock award activity for the six months ended December 31, 2017 is as follows:



	Number of Shares		Weighted Average Fair Value
Outstanding at June 30, 2017	318,584		$	11.97
Granted	278,889		$	13.63
Forfeited	(11,641	)	$	12.73
Outstanding at December 31, 2017	585,832		$	12.75

(1)	At December 31, 2017 and 2016, 22,321 and 181,040 stock options were outstanding, respectively. The effect of the shares that would be issued upon exercise of these options has been excluded from the calculation of diluted loss per share, for the three and six months ended December 31, 2017 and six months ended December 31, 2016, because those shares are anti-dilutive.

(2)

At December 31, 2017 and 2016, 335,869 and 350,771 additional shares of common stock, respectively, were issuable upon the settlement of outstanding restricted stock units. The effect of the shares that would be issued upon settlement of these restricted stock units has been excluded from the calculation of diluted loss per share, for the three and six months ended December 31, 2017 and six months ended December 31, 2016, because those shares are anti-dilutive.


(3)	At December 31, 2017 and 2016, 585,832 and 336,826 performance-based restricted stock awards, respectively, were outstanding. The effect of the shares that would be issued upon vesting of these awards has been excluded from the calculation of diluted loss per share, for the three and six months ended December 31, 2017 and six months ended December 31, 2016, because those shares are anti-dilutive.

Unvested time-based restricted stock awards that contain nonforfeitable rights to dividends are participating securities and included in the computation of earnings per share pursuant to the two-class method. Under this method, earnings attributable to the Company are allocated between common stockholders and the participating awards, as if the awards were a second class of stock. During periods of net income, the calculation of earnings per share excludes the income attributable to participating securities in the numerator and the dilutive impact of these securities from the denominator. In the event of a net loss, undistributed earnings are not allocated to participating securities and the denominator excludes the dilutive impact of these securities as they do not share in the losses of the Company. During the three months ended December 31, 2016, undistributed earnings allocated to participating securities were based on 573,016 time-based restricted stock awards.

9. Income Taxes

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law. Among other provisions, the Tax Act will lower the Federal statutory corporate income tax rate from 35% to 21%. Under ASC 740, Accounting for Income Taxes, the enactment of the Tax Act requires companies to recognize the effects of changes in tax laws and rates on deferred tax assets and liabilities and the retroactive effects of changes in tax laws in the period in which the new legislation is enacted. The Company has reviewed the provisions that will impact the Company, however, given that its deferred tax assets are offset by a full valuation allowance, the Company does not expect these changes to have a net impact on its financial position and net loss after the revaluation. There is no change to the Company’s assertion on maintaining a full valuation allowance against its deferred tax assets.

ITEM 2.	MANAGEMENT’S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

You should read the following discussion and analysis of our financial condition and results of operations together with our financial statements and the related notes appearing under Item 1 of Part I of this Quarterly Report on Form 10-Q. Some of the information contained in this discussion and analysis or set forth elsewhere in this report, including information with respect to our plans and strategy for our business and expected financial results, includes forward-looking statements that involve risks and uncertainties. You should review the “Risk Factors” discussed in our Annual Report on Form 10-K for the year ended

June 30, 2017 and subsequent reports on Form 10-Q, including in Item 1A of Part II of this Quarterly Report on Form 10-Q, for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis.

OVERVIEW

We are a medical technology company leading the way in the effort to successfully treat patients suffering from peripheral and coronary artery diseases, including those with arterial calcium, the most difficult arterial disease to treat. We are committed to clinical rigor, constant innovation and a defining drive to set the industry standard to deliver safe and effective medical devices that improve lives of patients facing these difficult disease states.

Our peripheral arterial disease (“PAD”) products, the Diamondback 360^® Peripheral Orbital Atherectomy System (“OAS”) (“Diamondback 360 Peripheral”), the Diamondback 360 60cm Peripheral OAS, the Diamondback 360 4 French 1.25 Peripheral OAS, the Diamondback 360 1.50 Peripheral OAS, the Diamondback 360 2.00 Peripheral OAS, and the Stealth 360^® Peripheral OAS (“Stealth 360”), are catheter-based platforms capable of treating a broad range of plaque types in leg arteries both above and below the knee, including calcified plaque, and address many of the limitations associated with other existing surgical, catheter and pharmacological treatment alternatives. The micro-invasive devices use small access sheaths that can provide procedural benefits and allow physicians to treat PAD patients in even the small and tortuous vessels located below the knee and facilitate access through alternative sites in the ankle, foot and wrist, as well as in the groin. We refer to each of the products above in this report as the “Peripheral OAS.”

The United States Food and Drug Administration (“FDA”) has granted us 510(k) clearances for our Peripheral OAS devices as a therapy in patients with PAD, as discussed in Item 1 of Part I of our Annual Report on Form 10-K for the year ended June 30, 2017.

Our coronary arterial disease (“CAD”) product, the Diamondback 360 Coronary OAS (“Coronary OAS”), is marketed as a treatment for severely calcified coronary arteries. The Coronary OAS is a catheter-based platform designed to facilitate stent delivery in patients with CAD who are acceptable candidates for percutaneous transluminal coronary angioplasty or stenting due to de novo, severely calcified coronary artery lesions. The Coronary OAS design is similar to technology used in our Peripheral OAS, customized specifically for the coronary application.

A coronary application required us to conduct a clinical trial and file a premarket approval (“PMA”) application and obtain approval from the FDA. In March 2013, we completed submission of our PMA application to the FDA for our orbital atherectomy system to treat calcified coronary arteries. In October 2013, we received PMA from the FDA to market the Coronary OAS as a treatment for severely calcified coronary arteries. We commenced a commercial launch of our Coronary OAS following receipt of PMA. In March 2017, we received approval from the FDA to market the Diamondback 360 Coronary OAS Micro Crown (the “Coronary OAS Micro Crown”). The Coronary OAS Micro Crown is the only atherectomy device designed to both pilot tight, calcific lesions and treat 2.5 to 4mm vessels with a single device.

We market the Peripheral and Coronary OAS in the United States through a direct sales force and expend significant capital on our sales and marketing efforts to expand our customer base and utilization per customer. At our facilities, we assemble the saline infusion pump and the single-use catheter used in the Peripheral and Coronary OAS with components purchased from third-party suppliers, as well as with components manufactured in-house. Ancillary products are purchased from third-party suppliers.

International

In November 2016, we signed an exclusive distribution agreement with Medikit Co., Ltd. (“Medikit”) to sell our Coronary and Peripheral OAS in Japan. In March 2017, we received approval from Japan’s Ministry of Health, Labor and Welfare for our Coronary OAS Micro Crown. On February 1, 2018, the Coronary OAS Micro Crown received reimbursement approval in Japan, followed by the first commercial sales, making Japan the first international market for any of our products. We are currently evaluating options for additional international markets to expand the coronary and peripheral opportunities.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT JUDGMENTS AND ESTIMATES

Our management’s discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States. The preparation of our consolidated financial statements requires us to make estimates, assumptions and judgments that affect amounts reported in those statements. Our estimates, assumptions and judgments, including those related to revenue recognition, allowance for doubtful accounts, excess and obsolete inventory, deferred revenue and stock-based compensation, are updated as appropriate at least quarterly. We use authoritative pronouncements, our technical accounting knowledge, cumulative business experience, judgment and other factors in the selection and application of our accounting policies. While we believe that the estimates, assumptions and judgments that we use in preparing our consolidated financial statements are appropriate, these estimates, assumptions and judgments are subject to factors and uncertainties regarding their outcome. Therefore, actual results may materially differ from these estimates.

Some of our significant accounting policies require us to make subjective or complex judgments or estimates. An accounting estimate is considered to be critical if it meets both of the following criteria: (1) the estimate requires assumptions about matters that are highly uncertain at the time the accounting estimate is made, and (2) different estimates that reasonably could have been used, or changes in the estimate that are reasonably likely to occur from period to period, would have a material impact on the presentation of our financial condition, results of operations, or cash flows.

Our critical accounting policies are identified in our Annual Report on Form 10-K for the fiscal year ended June 30, 2017 in Management’s Discussion and Analysis of Financial Condition and Results of Operations under the heading “Critical Accounting Policies and Significant Judgments and Estimates.”

Comparison of Three Months Ended December 31, 2017 with Three Months Ended December 31, 2016

Net revenues. Net revenues increased by $2.6 million, or 5.2%, from $50.0 million for the three months ended December 31, 2016 to $52.6 million for the three months ended December 31, 2017. Sales of our Peripheral OAS increased $1.9 million, or 5.5%, due to 8.3% more devices sold, partially offset by a 2.6% decrease in average selling price in the three months ended December 31, 2017 compared to the three months ended December 31, 2016. Coronary OAS revenues increased approximately 388,000, or 3.2%, due to 4.6% more devices sold, partially offset by a 1.3% decrease in average selling price in the three months ended December 31, 2017 compared to the three months ended December 31, 2016. Other product revenue increased by $323,000 for the three months ended December 31, 2017, driven by increased sales of our Peripheral and Coronary OAS, which the other products support.

Prior to February 2018, all of our revenues have been in the United States; however, sales in Japan commenced in February 2018. In November 2016, we signed an exclusive distribution agreement with Medikit to sell our Coronary and Peripheral OAS in Japan, and in March 2017, we received approval from Japan’s Ministry of Health, Labor and Welfare for our Coronary OAS Micro Crown. On February 1, 2018, the Coronary OAS Micro Crown received reimbursement approval in Japan, followed by the first commercial sales, making Japan the first international market for any of our products. We are evaluating options for additional international markets to expand the coronary and peripheral opportunities. We expect our revenue to increase as we continue to increase the number of physicians using the devices, increase the usage per physician, introduce new and improved products, generate additional clinical data, and expand into new geographies, partially offset by potential decreases in average selling price.

Cost of Goods Sold. Cost of goods sold increased $336,000, or 3.7%, from $9.2 million for the three months ended December 31, 2016 to $9.5 million for the three months ended December 31, 2017. Cost of goods sold represents the cost of materials, labor and overhead for single-use catheters, guidewires, saline pumps, and other ancillary products. Cost of goods sold for the three months ended December 31, 2017 and 2016 includes $73,000 and $175,000, respectively, for stock-based compensation. The increase in cost of goods sold was primarily due to more devices sold, partially offset by lower costs per unit driven by manufacturing efficiencies and cost reductions. Gross margin increased to 81.9% for the three months ended December 31, 2017 from 81.7% for the three months ended December 31, 2016 due to lower costs per unit. We expect that gross margin in the third quarter of fiscal 2018 will be slightly lower than the gross margin in the three months ended December 31, 2017. Quarterly margin fluctuations could occur based on production volumes, timing of new product introductions, sales mix, pricing changes, or other unanticipated circumstances.

Selling, General and Administrative Expenses. Our selling, general and administrative expenses increased by $3.0 million, or 8.9%, from $34.0 million for the three months ended December 31, 2016 to $37.0 million for the three months ended December 31, 2017. The increase was primarily due to increased payroll related expenses due to the expansion of our sales organization and severance benefits, and litigation and other legal expenses. These amounts were partially offset by lower incentive compensation expense. Selling, general and administrative expenses for the three months ended December 31, 2017 and 2016 include $2.3 million and $2.1 million, respectively, for stock-based compensation. We expect our selling, general and administrative expenses for the third quarter of fiscal 2018 to be higher than the amounts incurred for the three months ended December 31, 2017.

Research and Development Expenses. Research and development expenses increased by $591,000, or 10.2%, from $5.8 million for the three months ended December 31, 2016 to $6.4 million for the three months ended December 31, 2017. Research and development expenses relate to specific projects to develop new products or expand into new markets, such as the development of new versions of the Peripheral and Coronary OAS, shaft designs and crown designs, and to PAD and CAD clinical trials. The increase was primarily due to the commencement of our ECLIPSE clinical study. Research and development expenses for the three months ended December 31, 2017 and 2016 include $269,000 and $252,000, respectively, for stock-based compensation. We expect research and development expenses in the third quarter of fiscal 2018 to be higher than the amounts incurred for the three months ended December 31, 2017. Fluctuations could occur based on the number of projects and studies and the timing of expenditures.

Other (Income) Expense, Net. Other expense, net, was $105,000 and $15,000 for three months ended December 31, 2017 and 2016, respectively. The change was primarily due to $430,000 of interest expense related to the sale-leaseback of our facility that we completed in March 2017, partially offset by higher interest income due to our increased cash balance from the three months ended December 31, 2016, as well as interest related to the partial payment of the convertible note receivable.

Comparison of Six Months Ended December 31, 2017 with Six Months Ended December 31, 2016

Net revenues. Net revenues increased by $2.5 million, or 2.5%, from $99.8 million for the six months ended December 31, 2016 to $102.3 million for the six months ended December 31, 2017. Sales of our Peripheral OAS increased $1.8 million, or 2.6%, due to 6.3% more devices sold, partially offset by a 3.4% decrease in average selling price in the six months ended December 31, 2017 compared to the six months ended December 31, 2016. Coronary OAS revenues increased approximately $294,000, or 1.3%, due to 2.6% more devices sold, partially offset by a 1.3% decrease in average selling price in the six months ended December 31, 2017 compared to the six months ended December 31, 2016. Other product revenue increased by $327,000 for the six months ended December 31, 2017, driven by increased sales of our Peripheral and Coronary OAS, which the other products support. The factors that had an adverse effect on revenues in the six months ended December 31, 2017 included the effects of Hurricanes Harvey and Irma, and a recall of a version of our saline infusion pump.

Cost of Goods Sold. Cost of goods sold increased slightly to $18.7 million for the six months ended December 31, 2017 from $18.6 for the six months ended December 31, 2016. Cost of goods sold represents the cost of materials, labor and overhead for single-use catheters, guidewires, saline pumps, and other ancillary products. Cost of goods sold for the six months ended December 31, 2017 and 2016 includes $159,000 and $375,000, respectively, for stock-based compensation. The increase in cost of goods sold due higher sales levels was partially offset by lower costs per unit driven by manufacturing efficiencies and cost reductions. Gross margin increased slightly to 81.7% for the six months ended December 31, 2017 from 81.3% for the six months ended December 31, 2016 due to lower costs per unit.

Selling, General and Administrative Expenses. Our selling, general and administrative expenses increased by $2.0 million, or 2.7%, from $70.9 million for the six months ended December 31, 2016 to $72.9 million for the six months ended December 31, 2017. The increase was primarily due to increased payroll related expenses due to the expansion of our sales organization and severance benefits, and litigation and other legal expenses. These amounts were partially offset by lower incentive compensation expense. Selling, general and administrative expenses for each of the six months ended December 31, 2017 and 2016 include $5.0 million for stock-based compensation.

Research and Development Expenses. Research and development expenses increased by $1.6 million, or 14.0%, from $11.1 million for the six months ended December 31, 2016 to $12.7 million for the six months ended December 31, 2017. Research and development expenses relate to specific projects to develop new products or expand into new markets, such as the development of new versions of the Peripheral and Coronary OAS, shaft designs and crown designs, and to PAD and CAD clinical trials. The increase was primarily due to the commencement of our ECLIPSE clinical study and new development projects. Research and development expenses for the six months ended December 31, 2017 and 2016 include $590,000 and $541,000, respectively, for stock-based compensation.

Other (Income) Expense, Net. Other (income) expense, net was $297,000 and $(18,000) for six months ended December 31, 2017 and 2016, respectively. The change was primarily due to $862,000 of interest expense related to the sale-leaseback of our facility that we completed in March 2017, partially offset by higher interest income due to our increased cash balance from the six months ended December 31, 2016, as well as interest related to the partial payment of the convertible note receivable.

LIQUIDITY AND CAPITAL RESOURCES

We had cash and cash equivalents of $107.3 million and $107.9 million at December 31, 2017 and June 30, 2017, respectively. During the six months ended December 31, 2017, net cash used in operations was $825,000. As of December 31, 2017, we had an accumulated deficit of $331.7 million. We have historically funded our operating losses primarily from the issuance of common and preferred stock, convertible promissory notes, and debt.

Facility Sale

On December 29, 2016, we entered into a Purchase and Sale Agreement, as subsequently amended (collectively, the “Sale Agreement”), with Krishna Holdings, LLC (“Krishna”), providing for the sale to Krishna of our headquarters facility in St. Paul, Minnesota (the “Facility”), for a cash purchase price of $21.5 million. On March 30, 2017, the sale of the Facility under the Sale Agreement closed. We received proceeds of approximately $20.9 million ($21.5 million less $556,000 of transaction expenses).

We intend to use the net proceeds from the sale for working capital and general corporate purposes, which may include, but are not limited to:


•	the funding of clinical trials and studies;


•	sales and marketing programs;


•	expansion into international markets; and


•	development of new products.

We may also use a portion of the net proceeds for the potential acquisition of, or investments in, businesses, technologies and products, although we have no current understandings, commitments or arrangements to do so. We cannot specify with certainty all of the particular uses for the net proceeds. Accordingly, we will retain broad discretion over the use of these net proceeds.

Revolving Credit Facility

On March 31, 2017, we entered into a Loan and Security Agreement (the “Loan Agreement”) with Silicon Valley Bank (“SVB”). The Loan Agreement provides for a senior, secured revolving credit facility (the “Revolver”) of $40.0 million (the “Maximum Dollar Amount”).

Advances under the Revolver may be made from time to time up to the Maximum Dollar Amount, subject to certain borrowing limitations. The Revolver has a maturity date of March 31, 2020 and bears interest at a floating per annum rate equal to the Wall Street Journal prime rate, less 0.25%. Interest on borrowings is due monthly and the principal balance is due at maturity. Borrowings up to $10.0 million are available on a non-formula basis. Borrowings above $10.0 million are based on (i) 85% of eligible domestic accounts receivable, and (ii) the lesser of 50% of eligible inventory or $5.0 million, subject to adjustment as defined in Loan Agreement. Upon the Revolver’s maturity, any outstanding principal balance, unpaid accrued interest, and all other obligations under the Revolver will be due and payable. We will incur a fee equal to 1% of the Maximum Dollar Amount upon termination of the Loan Agreement or the Revolver for any reason prior to the maturity date, unless refinanced with SVB.

Our obligations under the Loan Agreement are secured by certain of our assets, including, among other things, accounts receivable, deposit accounts, inventory, equipment, general intangibles and records pertaining to the foregoing. The collateral does not include our intellectual property, but we agreed not to encumber our intellectual property without the consent of SVB. The Loan Agreement contains customary covenants limiting our ability to, among other things, incur debt or liens, make certain investments and loans, enter into transactions with affiliates, undergo certain fundamental changes, dispose of assets, or change the nature of its business. In addition, the Loan Agreement contains financial covenants requiring us to maintain, at all times when any amounts are outstanding under the Revolver, either (i) minimum unrestricted cash at SVB and unused availability on the Revolver of at least $10.0 million or (ii) minimum trailing three-month Adjusted EBITDA of $1.0 million. If we do not comply with the various covenants under the Loan Agreement, the interest rate on outstanding amounts will increase by 5% and SVB may, subject to various customary cure rights, decline to provide additional advances under the Revolver, require the immediate payment of all amounts outstanding under the Revolver, and foreclose on all collateral.

Under the Loan Agreement, we paid SVB a non-refundable commitment fee of $80,000, which will be amortized to interest expense over the term of the Loan Agreement. We are required to pay a fee equal to 0.35% per annum on the unused portion of the Revolver, payable quarterly in arrears. We are not obligated to draw any funds under the Revolver and have not done so under the Revolver since entering into the Loan Agreement. No amounts are outstanding as of December 31, 2017 and we currently do not have plans to borrow under the Loan Agreement.

Changes in Liquidity

Cash and Cash Equivalents. Cash and cash equivalents were $107.3 million at December 31, 2017 and $107.9 million at June 30, 2017. The decrease is primarily attributable to net cash used in our operating and investing activities during the six months ended December 31, 2017.

Operating Activities. Net cash (used in) provided by operations was $(825,000) and $13.8 million for the six months ended December 31, 2017 and 2016, respectively. For the six months ended December 31, 2017 and 2016, we had a net loss of $2.4 million and $815,000, respectively. Significant changes in working capital during these periods included:


•	Cash provided by (used in) accounts receivable was $561,000 and $(2.5) million during the six months ended December 31, 2017 and 2016, respectively, primarily due to the amount and timing of revenue and collections.

•

Cash (used in) provided by inventories was $(504,000) and $1.3 million during the six months ended December 31, 2017 and 2016, respectively. For the six months ended December 31, 2017, the amount of cash used in inventories was primarily due to higher levels of raw materials related to new products. For the six months ended December 31, 2016, the amount of cash provided by inventories was primarily due to lower inventory levels from better inventory management.


•	Cash provided by prepaid expenses and other current assets was $2.8 million and $1.9 million during the six months ended December 31, 2017 and 2016, respectively, primarily due to payment timing of vendor deposits and other expenditures. During the six months ended December 31, 2017, we also received proceeds from an insurance receivable related to a litigation settlement payment.


•	Cash used in accounts payable was $608,000 and $1.0 million during the six months ended December 31, 2017 and 2016, respectively, due to the amount and timing of purchases and vendor payments.

•

Cash used in accrued expenses and other liabilities was $8.4 million and $4.0 million during the six months ended December 31, 2017 and 2016, respectively. For the six months ended December 31, 2017, the change in accrued expenses was primarily due to the amount and timing of compensation payments, as well as a litigation settlement payment. For the six months ended December 31, 2016, the change in accrued expenses and other liabilities was primarily due to the initial $3.0 million Department of Justice settlement payment (discussed below), reduction of clinical accruals, severance payments and the amount and timing of compensation payments.


•	Cash provided by deferred revenue was $10.0 million during the six months ended December 31, 2016. In connection with the exclusive distribution agreement with Medikit to sell our Coronary and Peripheral OAS in Japan, Medikit made an upfront payment of $10.0 million to us, which will be recognized in relation to the estimated future sales under the agreement.

Investing Activities. Net cash used in investing activities was $1.7 million and $856,000 for the six months ended December 31, 2017 and 2016, respectively, primarily related to the purchase of property and equipment and patents. Cash used in the six months ended December 31, 2017, was partially offset by proceeds from a convertible note receivable and sales of marketable securities.

Financing Activities. Net cash provided by financing activities was $1.9 million and $5.7 million for the six months ended December 31, 2017 and 2016, respectively, primarily due to proceeds from employee stock purchases and the exercise of stock options.

Our future liquidity and capital requirements will be influenced by numerous factors, including the extent and duration of future operating losses, the level and timing of future sales and expenditures, the results and scope of ongoing research and product development programs, working capital required to support our business operations, the receipt of and time required to obtain regulatory clearances and approvals, our sales and marketing programs, the continuing acceptance of our products in the marketplace, competing technologies, market and regulatory developments, ongoing facility requirements, potential strategic transactions (including the potential acquisition of, or investments in, businesses, technologies and products), international expansion, and the existence, defense and resolution of legal claims and proceedings. As of December 31, 2017, we believe our current cash and cash equivalents will be sufficient to fund working capital requirements, capital expenditures and operations for the foreseeable future, including at least the next twelve months, as well as to fund payments related to the Department of Justice settlement, expenses relating to compliance with our Corporate Integrity Agreement (as defined below), payments under our lease agreements, payments under severance agreements and anticipated costs relating to litigation. We intend to retain any future earnings to support operations and to finance the growth and development of our business. We do not anticipate paying any dividends in the foreseeable future.

Legal Settlement

As previously discussed in our Annual Report on Form 10-K for the year ended June 30, 2017, filed with the SEC on August 24, 2017, on June 28, 2016, we entered into a Settlement Agreement with the DOJ, pursuant to which we agreed to pay $8.0 million (the “Settlement Amount”) as follows: an initial payment of $3.0 million, which we paid in July 2016, with the remaining $5.0 million, which bears interest at 1.8% per annum, payable in 11 equal quarterly installments, beginning in January 2017. Under the Settlement Agreement, if we make a single payment in excess of $2.0 million, which payment is not covered by an insurance policy, in settlement of any claims before paying the full Settlement Amount, the remaining unpaid balance of the Settlement Amount will become immediately due and payable, with interest accruing on the unpaid principal portion at an interest rate of 1.8% per annum.

In connection with the resolution of this matter, we entered into a five-year corporate integrity agreement (the “Corporate Integrity Agreement”) with the Office of Inspector General of the Department of Health and Human Services. The Corporate Integrity Agreement requires that we maintain our existing compliance programs and imposes certain expanded compliance-related requirements during the term of the Corporate Integrity Agreement, including establishment of specific procedures and requirements regarding consulting activities, co-marketing activities and other interactions with healthcare professionals and healthcare institutions and the sale and marketing of our products; ongoing monitoring, reporting, certification and training obligations; and the engagement of an independent review organization to perform certain auditing and reviews and prepare certain reports regarding our compliance with federal health care programs. In the event of a breach of the Corporate Integrity Agreement, we could become liable for payment of certain stipulated penalties or could be excluded from participation in federal health care programs. The Corporate Integrity Agreement will require us to invest additional amounts in our compliance program and pay fees and expenses of the independent review organization.

Facility Lease

The Company entered into a Lease Agreement (the “Lease Agreement”) with Krishna Holdings, LLC, Apex Holdings, LLC, Kashi Associates, LLC, Keva Holdings, LLC, S&V Ventures, LLC, Polo Group LLC, SPAV Holdings LLC, Star Associates LLC, and The Global Villa, LLC. The Lease Agreement has an initial term of fifteen years, with four consecutive renewal options of five years each, with a base annual rent in the first year of $1.6 million and annual escalations of 3%. See Note 3 to our Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for additional discussion.

Employee Litigation

As previously discussed in our Annual Report on Form 10-K for the year ended June 30, 2017, filed with the SEC on August 24, 2017 and in our Quarterly Report on Form 10-Q for the quarter ended September 30, 2017, filed with the SEC on November 3, 2017, we are party to Steven Babyak v. Cardiovascular Systems, Inc., a lawsuit originally filed in the Superior Court of California, County of Los Angeles, on November 16, 2015. Effective October 24, 2017, we entered into a Settlement Agreement with Mr. Babyak that settles all disputes and releases all claims between us and Mr. Babyak. We paid all amounts due under the Settlement Agreement in the three months ended December 31, 2017.

NON-GAAP FINANCIAL INFORMATION

To supplement our consolidated financial statements prepared in accordance with GAAP, our management uses a non-GAAP financial measure referred to as “Adjusted EBITDA.” The following table sets forth, for the periods indicated, a reconciliation of Adjusted EBITDA to the most comparable GAAP measure expressed as dollar amounts (in thousands):



	Six Months Ended December 31,
	2017			2016
Net loss	$	(2,390	)	$	(815	)
Less: Other (income) expense, net	297			(18		)
Less: Provision for income taxes	66			48
Loss from operations	(2,027		)	(785		)
Add: Stock-based compensation	5,740			5,933
Add: Depreciation and amortization	2,090			2,056
Adjusted EBITDA	$	5,803		$	7,204

Adjusted EBITDA decreased as compared to the prior year period due to the higher net loss in the six months ended December 31, 2017 compared to the six months ended December 31, 3016.

Use and Economic Substance of Non-GAAP Financial Measures Used and Usefulness of Such Non-GAAP Financial Measures to Investors

We use Adjusted EBITDA as a supplemental measure of performance and believe this measure facilitates operating performance comparisons from period to period and company to company by factoring out potential differences caused by depreciation and amortization expense and non-cash charges such as stock-based compensation. Our management uses Adjusted EBITDA to analyze the underlying trends in our business, assess the performance of our core operations, establish operational goals and forecasts that are used to allocate resources and evaluate our performance period over period and in relation to our competitors’ operating results. Additionally, our management is partially evaluated on the basis of Adjusted EBITDA when determining achievement of their incentive compensation performance targets.

We believe that presenting Adjusted EBITDA provides investors greater transparency to the information used by our management for its financial and operational decision-making and allows investors to see our results “through the eyes” of management. We also believe that providing this information better enables our investors to understand our operating performance and evaluate the methodology used by our management to evaluate and measure such performance.

The following is an explanation of each of the items that management excluded from Adjusted EBITDA and the reasons for excluding each of these individual items:


•	Stock-based compensation. Our management believes that excluding this item from our non-GAAP results is useful to investors to understand the application of stock-based compensation guidance and its impact on our operational performance and ability to make additional investments in the Company, and it allows for greater transparency to certain line items in our financial statements.


•	Depreciation and amortization expense. Our management believes that excluding these items from our non-GAAP results is useful to investors to understand our operational performance and ability to make additional investments in the company.

Material Limitations Associated with the Use of Non-GAAP Financial Measures and Manner in Which We Compensate for these Limitations

Non-GAAP financial measures have limitations as analytical tools and should not be considered in isolation or as a substitute for our financial results prepared in accordance with GAAP. Some of the limitations associated with our use of these non-GAAP financial measures are:


•	Items such as stock-based compensation do not directly affect our cash flow position; however, such items reflect economic costs to us and are not reflected in our Adjusted EBITDA, and therefore these non-GAAP measures do not reflect the full economic effect of these items.

Table of Contents


•	Non-GAAP financial measures are not based on any comprehensive set of accounting rules or principles and therefore other companies may calculate similarly titled non-GAAP financial measures differently than we do, limiting the usefulness of those measures for comparative purposes.


•	Our management exercises judgment in determining which types of charges or other items should be excluded from the non-GAAP financial measures we use.

We compensate for these limitations by relying primarily upon our GAAP results and using non-GAAP financial measures only supplementally.

INFLATION

We do not believe that inflation had a material impact on our business and operating results during the periods presented.

OFF-BALANCE SHEET ARRANGEMENTS

Since inception, we have not engaged in any off-balance sheet activities as defined in Item 303(a)(4) of Regulation S-K.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

The primary objective of our investment activity is to preserve our capital for the purpose of funding operations, while at the same time maximizing the income we receive from our investments without significantly increasing risk or decreasing availability. To achieve these objectives, our investment policy allows us to maintain a portfolio of cash equivalents and investments in a variety of marketable securities, including money market funds, U.S. government securities, and certain bank obligations. Our cash and cash equivalents as of December 31, 2017 include liquid money market accounts. Due to the short-term nature of these investments, we believe that there is no material exposure to interest rate risk.

Additionally, we have acquired certain available-for-sale marketable securities under our deferred compensation plan. See Note 5 to our Consolidated Financial Statements included in Item 1 of Part I of this Quarterly Report on Form 10-Q for additional information on these available-for-sale marketable securities.

ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Our Chief Executive Officer and Chief Financial Officer, referred to collectively herein as the Certifying Officers, are responsible for establishing and maintaining our disclosure controls and procedures. The Certifying Officers have reviewed and evaluated the effectiveness of the Company’s disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) as of December 31, 2017. Based on that review and evaluation, which included inquiries made to certain other employees of the Company, the Certifying Officers have concluded that, as of the end of the period covered by this Report, the Company’s disclosure controls and procedures, as designed and implemented, are effective.

Changes in Internal Control Over Financial Reporting

There were no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended December 31, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 1A. RISK FACTORS

In addition to the other information set forth in this report, including the important information in the section entitled “Private Securities Litigation Reform Act,” you should carefully consider the “Risk Factors” discussed in our Form 10-K for the year ended June 30, 2017 filed with the SEC on August 24, 2017 and our subsequent reports on Form 10-Q for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in this report and materially adversely affect our financial condition or future results. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial might materially adversely affect our actual business, financial condition and/or operating results. In addition, you should consider the following risk factor:

The recently passed Tax Cuts and Jobs Act of 2017 may have a significant impact on our financial condition and results of operations.

The Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law on December 22, 2017. The Tax Act made numerous changes to U.S. federal corporate tax law and is expected to reduce our effective tax rate for fiscal year 2018 and future periods. Effective January 1, 2018, the Tax Act lowers the U.S. corporate tax rate from 35% to 21% and prompts various other changes to U.S. federal corporate tax law. We are currently assessing the impact the Tax Act will have on our deferred tax assets with our professional advisors and until our analysis is complete, the full impact the Tax Act will have on us in future periods is uncertain and may adversely affect our financial condition and results of operations.

The effects of hurricanes, flooding and other natural disasters may impact our sales, inventories and supply availability, which could adversely affect our financial condition and results of operations.

In August and September 2017, Hurricanes Harvey and Irma made landfall along the Texas Gulf Coast and in the State of Florida, respectively, bringing high winds, unprecedented rain and extreme flooding to those areas. A significant portion of our sales is generated from these areas. Procedure volumes in the Houston area and in Florida decreased during the pendency and immediate aftermath of the hurricanes and flooding, which decreased the number of our products used during this time. Any sustained decrease in procedure volumes from hurricanes and other natural disasters that affect any areas in which our customers are located will result in decreased sales in these areas and could have a material adverse effect on our financial condition and results of operations.

In addition, we maintain a 46,000-square foot production facility in Pearland, Texas, which is just outside of Houston in southeast Texas. The storm and its aftermath did not cause damage to our Pearland facility, which remains open.
