2. ACQUISITIONS

RadiaDyne Acquisition

On September 21, 2018, the Company acquired RadiaDyne, a privately held medical diagnostic and device company that designs and develops patient dose monitoring technology to improve cancer treatment outcomes. The aggregate purchase price of $75.0 million included an upfront payment of $47.9 million, contingent consideration with an estimated fair value of $22.3 million, an indemnification holdback of $4.6 million and a purchase price holdback of $0.2 million. The fair value of $22.3 million in contingent consideration is comprised of $16.5 million for the revenue milestones and $5.8 million for the technical milestones. The $4.6 million indemnification holdback is recorded in other long-termaccrued liabilities at August 31, 2019 and the $0.2 million purchase price holdback iswas initially recorded in accrued liabilities.liabilities, and was paid during the third quarter of fiscal year 2019.
This acquisition expands the Company’s growing Oncology business by adding RadiaDyne’s early-stage, proprietary OARtrac® real-time radiation dose monitoring platform and other market-leading oncology solutions, including the IsoLoc®/ImmobiLoc® and Alatus® balloon stabilizing technologies.
The Company accounted for the RadiaDyne acquisition under the acquisition method of accounting for business combinations. Accordingly, the cost to acquire the assets was allocated to the underlying net assets in proportion to estimates of their respective fair values. The excess of the purchase price over the estimated fair value of the net assets acquired was recorded as goodwill. Goodwill is deductible for income tax purposes.
The Company has not disclosed the amount of revenue and earnings for sales of RadiaDyne products since acquisition, nor proforma information, because these amounts are not significant to the Company's financial statements. Acquisition-related costs associated with the RadiaDyne acquisition, which are included in acquisition,"acquisition, restructuring and other expenses, netnet" in the accompanying consolidated statementsConsolidated Statements of income,Operations, were approximately $1.6 million.million in fiscal year 2019.

The values assigned to the RadiaDyne and OarTracOARtrac trademark and product technologies were derived using the relief-from-royalties method under the income approach. This approach is used to estimate the cost savings that accrue for the owner of an intangible asset who would otherwise have to pay royalties or licensing fees on revenues earned through the use of the asset if they had not owned the rights to use the assets. The net after-tax royalty savings are calculated for each year in the remaining economic life of the intangible asset and discounted to present value. The trademarks are deemed to have a useful life of five to seven years and the product technologies are deemed to have a useful life of seven to ten years. Both are amortized on a straight-line basis over their useful life.
The value assigned to customer relationships was derived using the multi-period excess earnings method under the income approach. This approach estimates the excess earnings generated over the lives of the customers that existed as of the acquisition date and discounts such earnings to present value. Customer relationships are amortized on a straight-line basis over fifteen years.
The goodwill arising from the acquisition consists largely of synergies and economies of scale the Company hopes to achieve from combining the acquired assets with the Company's current operations.
BioSentry Acquisition
On August 14, 2018, the Company acquired the BioSentry product from Surgical Specialties, LLC (“SSC”), for an aggregate purchase price of $39.8 million of which $37.0 million was paid on August 14, 2018 and $2.8 million was recorded as contingent consideration. The contingent consideration liability was recorded at fair value and will be payable to SSCwas paid in the fourth quarter of fiscal year 2019 upon fulfillment of certain hydrogel orders.orders by SSC.
The Company accounted for the BioSentry acquisition under the acquisition method of accounting for business combinations. Accordingly, the cost to acquire the assets was allocated to the underlying net assets in proportion to estimates of their respective fair values. The excess of the purchase price over the estimated fair value of the net assets acquired was recorded as goodwill. Goodwill is deductible for income tax purposes.

3. DIVESTITURES    

Fluid Management
On May 31, 2019, the Company completed the sale of the NAMIC Fluid Management business (the “Divestiture”) and all of the assets used primarily in connection with the Fluid Management business to Medline Industries, Inc. (“Medline”) pursuant to an asset purchase agreement dated April 17, 2019 (the “Asset Purchase Agreement”). Total consideration received by the Company for the Divestiture in the fourth quarter of fiscal year 2019 was $169.2 million in cash and resulted in a gain of $46.6 million after working capital adjustments of $0.6 million. The gain was recorded in discontinued operations. On June 3, 2019, a portion of the net proceeds were used to retire the outstanding balance on the Term Loan and Revolving Facility and the remaining net proceeds will continue to be invested in the business.
Pursuant to a transition services agreement entered into and effective on the closing of the transaction, the Company will supply certain services to Medline. Medline will receive certain legal, human resource, tax, accounting and information technology services from the Company for a period generally not to exceed 24 months.
As a result of the Divestiture, the results of operations from the Fluid Management business are reported in the accompanying Consolidated Statements of Operations as “Income from discontinued operations, net of income tax” for the

three months ended August 31, 2018. The following table summarizes the financial results of our discontinued operations:

4. REVENUE FROM CONTRACTS WITH CUSTOMERS

Adoption of ASC Topic 606 "Revenue from Contracts with Customers"
The Company adopted ASC 606, Revenue from Contracts with Customers on June 1, 2018 using the modified retrospective method for all contracts not completed as of the date of adoption. The reported results for fiscal 2019 reflect the application of ASC 606 guidance while the reported results for fiscal 2018 were prepared under the guidance of ASC 605, Revenue Recognition (“ASC 605”). For discussion of the Company’s accounting policy for revenue recognition under ASC 605, refer to Item 8 of the Annual Report on Form 10-K for the year ended May 31, 2018. The adoption of ASC 606 did not have an impact on the Company’s consolidated balance sheet, results of operations, equity or cash flows as of the adoption date or for the periods presented, other than the enhanced disclosures included in this footnote.
Revenue Recognition

Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to the performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

The Company has one primary revenue stream which is the sales of its products.

Net Product Revenue
The Company's products consist of a wide range of medical, surgical and diagnostic devices used by professional healthcare providers for vascular access, for the treatment of peripheral vascular disease and for use in oncology and surgical settings. The Company's devices are generally used in minimally invasive, image-guided procedures. Most of the Company's products are intended to be used once and then discarded, or they may be temporarily implanted for short-short or longer-termlong term use. The Company sells its products to its distribution partners and to end users, such as interventional radiologists, interventional cardiologists, vascular surgeons, urologists, interventional and surgical oncologists and critical care nurses.
Contracts and Performance Obligations
The Company contracts with its customers based on customer purchase orders, which in many cases are governed by master purchasing agreements. The Company’s contracts with customers are generally for product only, and do not include other performance obligations such as services or other material rights. As part of its assessment of each contract, the Company evaluates certain factors including the customer’s ability to pay (or credit risk). For each contract, the Company considers the promise to transfer products, each of which is distinct, to be the identified performance obligations.
Transaction Price and Allocation to Performance Obligations
Transaction prices of products are typically based on contracted rates. Product revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring products to a customer. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price utilizing the expected value method. As such, revenue is recorded net of rebates, returns and other deductions.
If a contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price based on the estimated relative standalone selling prices of the promised products underlying each performance obligation. The Company has standard pricing for its products and determines standalone selling prices based on the price at which the performance obligation is sold separately.




Revenue Recognition
Revenue is recognized when control of the product is transferred to the customer (i.e., when the Company’s performance obligation is satisfied), which occurs at a point in time, and may be upon shipment from the Company’s manufacturing site or delivery to the customer’s named location, based on the contractual shipping terms of a contract.
In determining whether control has transferred, the Company considers if there is a present right to payment from the customer and when physical possession, legal title and risks and rewards of ownership have transferred to the customer.
The Company typically invoices customers upon satisfaction of identified performance obligations. As the Company’s standard payment terms are 30 to 90 days from invoicing, the Company does not provide any significant financing to its customers.

Sales, value add, and other taxes collected on behalf of third parties are excluded from revenue.
Variable Consideration
Revenues from product sales are recorded at the net sales price (transaction price), which includes estimates of variable consideration for which reserves are established for discounts, returns, rebates and allowances that are offered within contracts between the Company and its customers. These reserves are based on the amounts earned or to be claimed on the related sales and are classified as a current liability.
Rebates and Allowances: The Company provides certain customers with rebates and allowances that are explicitly stated in the Company’s contracts and are recorded as a reduction of revenue in the period the related product revenue is recognized. The Company establishes a liability for such amounts, which is included in accrued expenses in the accompanying condensed consolidated balance sheets.Consolidated Balance Sheets. These rebates and allowances result from performance-based offers that are primarily based on attaining contractually specified sales volumes and administrative fees the Company is required to pay to group purchasing organizations.
Product Returns: The Company generally offers customers a limited right of return. Product returns after 30 days must be pre-approved by the Company and customers may be subject to a 20% restocking charge. To be accepted, a returned product must be unadulterated, undamaged and have at least twelve months remaining prior to its expiration date. The Company estimates the amount of its product sales that may be returned by its customers and records this estimate as a reduction of revenue in the period the related product revenue is recognized. The Company currently estimates product return liabilities using its historical product return information and considers other factors that it believes could significantly impact its expected returns, including product recalls. During the sixthree months ended November 30, 2018,August 31, 2019, such product returns were not material.
Contract Balances with Customers
A receivable is recognized in the period the Company ships the product. Payment terms on invoiced amounts are based on contractual terms with each customer and generally coincide with revenue recognition. Accordingly, the Company does not have any contract assets associated with the future right to invoice its customers. In some cases, if control of the product has not yet transferred to the customer or the timing of the payments made by the customer precedes the Company’s fulfillment of the performance obligation, the Company recognizes a contract liability that is included in deferred revenue in the accompanying condensed consolidated balance sheets.Consolidated Balance Sheets.
The following table presents changes in the Company’s receivables, contract assets and contract liabilities with customers:
Nov 30, 2018 May 31, 2018

During the sixthree months ended November 30, 2018,August 31, 2019, the Company recognized $0.2 million in revenue that was included in contract liabilities as of the beginning of the period. This was offset by additions to contract liabilities of $0.2$0.1 million.



Costs to Obtain or Fulfill a Customer Contract
Prior to the adoption of ASC 606, the Company expensed incremental commissions paid to sales representatives for obtaining product sales. Under ASC 606, the Company recognizes an asset for incremental costs of obtaining a contract with a customer if it expects to recover those costs. The Company’s sales incentive compensation plans qualify for capitalization since these plans are directly related to sales achieved during a period of time. However, the Company has elected the practical expedient under ASC 340-40-25-4 to expense the costs as they are incurred within selling and marketing expenses since the amortization period is less than one year.
The Company accounts for shipping and handling activities related to contracts with customers as costs to fulfill the promise to transfer the associated products. Shipping and handling costs, associated with the distribution of finished products to customers, are recorded in costs of goods sold and are recognized when the related finished product is shipped to the customer. Amounts charged to customers for shipping are recorded in net sales.

4.5. INVENTORIES
Inventories are stated at lower of cost and net realizable value (using the first-in, first-out method). Inventories consisted of the following:

Inventories$50,637

The Company periodically reviews for both obsolescence and loss of value. The Company makes assumptions about the future demand for and market value of the inventory. Based on these assumptions, the Company estimates the amount of obsolete, expiring and slow moving inventory. The total inventory reserve at November 30, 2018August 31, 2019 and May 31, 20182019 was $5.0$4.1 million and $6.1$4.2 million, respectively. Of the $5.0$4.1 million reserve as of November 30, 2018,August 31, 2019 and the $4.2 million reserve as of May 31, 2019, $0.4 million relates to the inventory reserve for Acculis inventory as a result of the recall announced in the fourth quarter of fiscal year 2017 and $0.7 million relates to a specific reserve related to the termination of an agreement with a Japanese distributor in the second quarter of fiscal year 2018. Of the $6.1 million reserve as of May 31, 2018, $1.6 million relates to the inventory reserve for Acculis inventory as a result of the recall announced in the fourth quarter of fiscal year 2017 and $0.7 million relates to a specific reserve related to the termination of an agreement with a Japanese distributor in the second quarter of fiscal year 2018.

5.6. GOODWILL AND INTANGIBLE ASSETS

Intangible assets other than goodwill are amortized over their estimated useful lives on either a straight-line basis or proportionately to the benefit being realized. Useful lives range from two to eighteen years. The Company periodically reviews the estimated useful lives of its intangible assets and reviews such assets or asset groups for impairment whenever events or changes in circumstances indicate that the carrying value of the assets or asset groups may not be recoverable. If an intangible asset or asset group is considered to be impaired, the amount of the impairment will equal the excess of the carrying value over the fair value of the asset.

Goodwill is not amortized, but rather, is tested for impairment annually or more frequently if impairment indicators arise. Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in each business combination.

The changes in the carrying amount of goodwill for the six months ended November 30, 2018 were as follows:

(in thousands) 
Goodwill balance at May 31, 2018$361,252
Additions for BioSentry acquisition (Note 2)14,140
Additions for RadiaDyne acquisition (Note 2)51,482
Goodwill balance at November 30, 2018$426,874



The Company's annual testing for impairment of goodwill was completed as of December 31, 2017.2018. The Company operates as a single operating segment with one1 reporting unit and consequently evaluates goodwill for impairment based on an evaluation of the fair value of the Company as a whole. The Company determines the fair value of the reporting unit based on the market valuation approach and concluded that it was not more-likely-than-not that the fair value of the Company's reporting unit was less than its carrying value.

Even though the Company determined that there was no0 goodwill impairment as of December 31, 2017,2018, the future occurrence of a potential indicator of impairment, such as a significant adverse change in legal, regulatory, business or economic conditions or a more-likely-than-not expectation that the reporting unit or a significant portion of the reporting unit will be sold or disposed of, would require an interim assessment for the reporting unit prior to the next required annual assessment as of December 31, 2018. The Company continued2019. There were no adjustments to assessgoodwill for potential impairment through November 30, 2018 and noted no events that would be considered a triggering event.the three months ended August 31, 2019.

7.8. LONG TERM DEBT

On November 7, 2016,June 3, 2019 and in connection with the completion of the Fluid Management divestiture, the Company repaid all amounts outstanding under its existing Credit Agreement and entered into a new Credit Agreement (the “Credit Agreement”) with the lenders party thereto, JPMorgan Chase Bank, N.A., as administrative agent, and Bank of America, N.A. and KeybankKeyBank National Association, as co-syndication agents, and JPMorgan Chase Bank, N.A., Merrill Lynch, Pierce, Fenner & Smith Incorporated and Keybank National Association as joint bookrunners and joint lead arrangers.agents.
The Credit Agreement provides for a $100.0$125.0 million senior secured term loan facility (“Term Loan”) and a $150.0 million senior secured revolving credit facility which includes up to a $20.0 million sublimit for letters of credit and a $5.0 million sublimit for swingline loans (the “Revolving Facility”), and together with the Term Loan, the “Facilities”).
On November 7, 2016,which includes an uncommitted expansion feature that allows the Company borrowed $100.0 million underto increase the Term Loantotal revolving commitments and/or add new tranches of term loans in an aggregate amount not to exceed $75.0 million.  The proceeds may be used to refinance certain existing indebtedness of the Company and approximately $16.5 millionits subsidiaries, to finance the working capital needs, and for general corporate purposes (including permitted acquisitions), of the Company and its subsidiaries.
The Credit Agreement has a five year maturity. Interest on the facility will be based, at the Company’s option, on a base rate of LIBOR plus an applicable margin tied to the Company’s total leverage ratio and having ranges between 0.25% and 0.75% for base rate loans and between 1.25% and 1.75% for LIBOR loans. After default, the interest rate may be increased by 2.0%. The facility will also carry a commitment fee of 0.20% to 0.25% per annum on the unused portion.

8.9. INCOME TAXES
The Company provides for income taxes at the end of each interim period based on the estimated effective tax rate for the full fiscal year adjusted for any discrete events, which are recorded in the period that they occur.  The estimated annual effective tax rate prior to discrete items was 26.3%8.3% in the secondfirst quarter of fiscal 2019,2020, as compared to 59.8%17.8% for the same period in fiscal 2018.2019. In fiscal 2019,2020, the Company’s effective tax rate differs from the U.S. statutory rate primarily due to the impact of the valuation allowance, foreign taxes, and state taxes.other non-deductible permanent items (such as non-deductible meals and entertainment, Section 162(m) excess compensation and non-deductible stock based compensation).
On December 22, 2017, the United States enacted the Tax Cuts and Jobs Act of 2017 (the “Tax Reform Act”). The Tax Reform Act is significant and has wide-ranging effects.
The Company is still studying all of the ramifications of the Tax Reform Act, but expects the primary material impact of the Act to be the remeasurement of the Company’s naked credit deferred tax liability, which was recorded in fiscal 2018 as a result of the reduction in U.S. corporate tax rates from 35% to 21%. The Tax Reform Act imposes a one-time transition tax on the deemed repatriation of post-1986 undistributed foreign subsidiaries’ earnings. Based on the information available as of December 31, 2017, the Company estimated undistributed foreign earnings in fiscal 2018. The taxable income arising from this deemed repatriation is expected to result in the utilization of net operating loss carryforwards and other tax credits, offset by changes in the valuation allowance, resulting in no net impact to tax expense. No changes have been made to these estimates and the Company expects to complete its accounting for these items within the prescribed measurement period.
The Tax Reform Act also creates a new requirement that certain income earned by foreign subsidiaries (“GILTI”), must be included in U.S. gross income. The FASB allows an accounting policy election of either recognizing deferred taxes for temporary differences expected to reverse as GILTI in future years or recognizing such taxes as a current period expense when incurred. The Company has not yet adopted an accounting policy.
The Company regularly assesses its ability to realize its deferred tax assets. Assessing the realization of deferred tax assets requires significant management judgment. In determining whether its deferred tax assets are more likely than not realizable, the Company evaluated all available positive and negative evidence, and weighted the evidence based on its objectivity. Evidence that the Company considered included its history of net operating losses, which resulted in the Company recording a full valuation allowance for its deferred tax assets in fiscal 2016, except the naked credit deferred tax liability.

Based on the review of all available evidence, the Company determined that it has not yet attained a sustained level of profitability and the objectively verifiable negative evidence outweighed the positive evidence. Therefore, the Company has provided a valuation allowance on its federal and state net operating loss carryforwards, federal and state R&D credit carryforwards and other net deferred tax assets that have a limited life and are not supportable by the naked credit deferred tax liability sourced income as of November 30, 2018.August 31, 2019. The Company will continue to assess the level of the valuation allowance required. If sufficient positive evidence exists in future periods to support a release of some or all of the valuation allowance, such a release would likely have a material impact on the Company’s results of operations.

10. SHARE-BASED COMPENSATION

The Company has two stock-based compensation plans that provide for the issuance of up to approximately 11.3 million shares of common stock. The 2004 Stock and Incentive Award Plan (the "2004 Plan") provides for the grant of incentive options to the Company's employees and for the grant of non-statutory stock options, restricted stock, stock appreciation rights, performance units, performance shares and other incentive awards to the Company's employees, directors and other service providers. The Company also has an employee stock purchase plan.

For the three months ended November 30,August 31, 2019 and 2018, and 2017, share-based compensation expense was $2.6$1.9 million and $2.0 million, respectively. For the six months ended November 30, 2018 and 2017, share-based compensation expense was $4.7 million and $3.8$2.2 million, respectively.

During the sixthree months ended November 30,August 31, 2019 and 2018, and 2017, the Company granted stock options and restricted stock units under the 2004 Plan to certain employees and members of the Board of Directors. Stock option awards are valued using the Black-Scholes option-pricing model and then amortized on a straight-line basis over the requisite service period of the award. Restricted stock unit awards are valued based on the closing trading value of the Company's shares on the date of grant and then amortized on a straight-line basis over the requisite service period of the award.

In the first six months of fiscal year 2019, the Company granted market-based performance share awards under the 2004 Plan to certain employees. The awards may be earned by achieving relative performance levels over the three year requisite service period. The performance criteria are based on the total shareholder return ("TSR") of the Company's common stock

relative to the TSR of the common stock of a pre-defined industry peer-group. The fair value of these awards are based on the closing trading value of the Company's shares on the date of grant and use a Monte Carlo simulation model.

As of November 30, 2018,August 31, 2019, there was $18.0$16.6 million of unrecognized compensation expense related to share-based payment arrangements. These costs are expected to be recognized over a weighted-average period of approximately four years. The Company has sufficient shares to satisfy expected share-based payment arrangements.

10.11. EARNINGS PER SHARE
Basic earnings per share is based on the weighted average number of common shares outstanding without consideration of potential common stock. Diluted earnings per share includes the dilutive effect of potential common stock consisting of stock options, restricted stock units and performance stock units, provided that the inclusion of such securities is not anti-dilutive. In periods with a net loss, stock options and restricted stock units are not included in the computation of diluted loss per share as the impact would be anti-dilutive.

12.13. FAIR VALUE

On a recurring basis, the Company measures certain financial assets and financial liabilities at fair value based upon quoted market prices, where available. Where quoted market prices or other observable inputs are not available, the Company applies valuation techniques to estimate fair value. FASB ASC Topic 820, Fair Value Measurements and Disclosures, establishes a three-level valuation hierarchy for disclosure of fair value measurements. The categorization of financial assets and financial liabilities within the valuation hierarchy is based upon the lowest level of input that is significant to the measurement of fair value. The three levels of the hierarchy are defined as follows:

Level 1 - Inputs to the valuation methodology are quoted market prices for identical assets or liabilities.

Level 2 - Inputs to the valuation methodology are other observable inputs, including quoted market prices for similar assets or liabilities and market-corroborated inputs.

Level 3 - Inputs to the valuation methodology are unobservable inputs based on management’s best estimate of inputs market participants would use in pricing the asset or liability at the measurement date, including assumptions about risk.


The Company's financial instruments include cash and cash equivalents, marketable securities, accounts receivable, accounts payable and contingent consideration. The carrying amount of cash and cash equivalents, accounts receivable, and accounts payable approximates fair value due to the immediate or short-term maturities. The Company's recurring fair value measurements using significant unobservable inputs (Level 3) relate to the Company's marketable securities, which are comprised of auction rate securities, and contingent consideration.consideration liabilities.
The following tables provide information by level for assets and liabilities that are measured at fair value on a recurring basis as of November 30, 2018August 31, 2019 and May 31, 2018:

Short-term Investments
Short-term investments consist of highly liquid investments in municipal bonds that reset on a weekly basis and can be called at any point in time.
Marketable Securities
Marketable securities consist solely of an auction rate security. Assumptions associated with the auction rate security include the interest rate benchmarks, the probability of full repayment of the principal considering the credit quality and guarantees in place, and the rate of return required by investors to own such securities given the current liquidity risk.
Contingent Consideration for Acquisition Earn Outs
Some of the Company's business combinations involve the potential for the payment of future contingent consideration upon the achievement of certain product development milestones or various other performance conditions. Payment of the additional consideration is generally contingent on the acquired company reaching certain performance milestones, including attaining specified revenue levels or product development targets. Contingent consideration is recorded at the estimated fair value of the contingent payments on the acquisition date. The fair value of the contingent consideration is remeasured at the estimated fair value at each reporting period with the change in fair value recognized as income or expense within change in fair value of contingent consideration in the consolidated statementsConsolidated Statements of income.Operations.

The Company measures the initial liability and remeasures the liability on a recurring basis using Level 3 inputs as defined under authoritative guidance for fair value measurements. The fair value is determined using a discounted cash flow model applied to projected net sales, using probabilities of achieving projected net sales and projected payment dates. Projected net sales are based on the Company's internal projections and extensive analysis of the target market and the sales potential.

Increases or decreases in any valuation inputs in isolation may result in a significantly lower or higher fair value measurement in the future.


The recurring Level 3 fair value measurements of the contingent consideration liabilities include the following significant unobservable inputs as of November 30, 2018:August 31, 2019:

At November 30, 2018,August 31, 2019, the range of estimated potential undiscounted future contingent consideration that the Company expects to pay as a result of all completed acquisitions is approximately $31.1$14.0 million to $41.1$34.0 million. The milestones, including revenue projections and technical milestones, associated with the contingent consideration must be reached in future periods ranging from fiscal years 20192020 to 2023 in order for the associated consideration to be paid.

13. MARKETABLE SECURITIES

On June 1, 2019, the Company adopted ASU No. 2016-02 using the specific identification method. modified retrospective approach. This ASU increases transparency and comparability among organizations by recognizing lease assets and liabilities on the balance sheet and disclosing key information about leasing arrangements. Comparative periods prior to adoption have not been retrospectively adjusted.

The Company holdselected the three practical expedients that permit an investment in an auction rate security that is high credit qualityentity to a) not reassess whether expired or existing contracts contain leases, b) not reassess lease classification for existing or expired leases, and generally achieved with municipal bond insurance. Sell orders for any security traded through an auction process could exceed bids and, in such cases,c) not consider whether previously capitalized initial direct costs would be appropriate under the auction fails andnew standard. Further, the Company may be unablehas elected to liquidate its positionnot recognize leases with terms of 12 months or less on the balance sheet, and elected to account for lease and non-lease components as a single component for certain classes of assets.

The adoption of this standard resulted in the security inrecording of an additional lease asset and lease liability of approximately $5.6 million. The standard did not have a material impact on the near term.Company's Consolidated Statement of Operations, Stockholders Equity or Cash Flows.

Leases
The Company determines if an arrangement is a lease at inception of the contract. The Company has operating leases for buildings, primarily for office space, R&D, manufacturing and warehousing.

Operating lease right-of-use (“ROU”) assets and operating lease liabilities are recognized based on the present value of the future minimum lease payments over the lease term at commencement date. Many of the lease agreements contain renewal or termination clauses that are factored into the determination of the lease term if it is reasonably certain that these options would be exercised. The Company recognizes lease expense for these leases on a straight-line basis over the lease term.

C.R. Bard, Inc. v. AngioDynamics, Inc.

On January 11, 2012, C.R. Bard, Inc. (“Bard”) filed a suit in the United States District Court of Utah claiming certain of the Company's implantable port products infringe on three3 U.S. patents held by Bard (the "Utah Action"). Bard’s Complaintcomplaint sought unspecified damages and other relief. The Company filed petitions for reexamination in the US Patent and Trademark Office ("USPTO") seeking to invalidate all three3 patents asserted by Bard in the litigation. The Company's petitions were granted and 40 of Bard's 41 patent claims were rejected and, following further proceedings, the Patent Office issued a Final Rejection of all 4000040 claims subject to reexamination. Thereafter, Bard filed appeals to the USPTO Board of Appeals and Interferences for all three reexaminations. The Patent Office issued decisions in all three appeals.3 reexaminations which were decided as follows: In one (issued on March 11, 2016 for US Patent No. 7,785,302), the rejections of six6 of the ten10 claims under reexamination were affirmed, but were reversed on four4 of the ten claims. In the second (issued on March 24, 2016 for U.S. Patent No. 7,959,615), the rejections of eight8 of the ten10 claims under reexamination were affirmed but the rejections of the other two2 of the ten claims were reversed. In the third (issued on March 29 for U.S. Patent No. 7,947.022)7,947,022) the rejections of all twenty20 claims under reexamination were affirmed.

On March 10, 2015, C.R. Bard Inc. ("Bard") and Bard Peripheral Vascular, Inc. (“BPV”)BPV filed suit in the United States District Court for the District of Delaware (the “Delaware Action") claiming certain of the Company's implantable port products infringe on three3 other U.S. patents held by Bard, (the “Delaware Action").which are different from those asserted in the Utah action. Bard's complaint seeks unspecified damages and other relief. The patents asserted in the Delaware Action are different than those asserted in the Utah Action. On June 1, 2015, the Company filed two2 motions in response to Bard’s Complaint - one sought transfer to the District of Utah where the Utah Action is currently pending, and the other sought dismissal of the entire complaint on grounds that none of the claims in the asserted patents is directed to patent eligible subject matter under Section 101 of the Patent Statute and in light of recent authority from the U. S. Supreme Court.

On January 12, 2016, the Court issued a decision denying both motions. A Markman hearing was held on March 10, 2017 and the Court issued its Claim Construction Order on May 19, 2017. On May 19, 2017, Bard served its Final Infringement Contentions and on June 2, 2017, the Company served its Final Invalidity Contentions.

Jury selection was held on Friday March 1, 2019 and trial began on March 4, 2019.  On day four of the jury trial, at the close of C.R. Bard’s case (Plaintiff), Judge Bataillon granted judgment as a matter of law under rule 50(a) in favor of AngioDynamics, dismissing Bard’s suit.  On April 5, 2019, Bard filed a precautionary Notice of Appeal to the Federal Circuit. On April 26, 2019, the District Court issued a Memorandum and Order confirming the grant of judgment in the Company’s favor of patent ineligibility, non-infringement, patent invalidity and no willful infringement. Meanwhile, on May 10, 2019, the Company believes thesefiled a Motion for Attorney fees and non-taxable expenses under 35 USC Sec. 285. On May 21, 2019, the Court issued a Memorandum and Order which, inter alia, stayed proceedings on the Company’s fee Motion and the Company’s equitable claims pending appeal; and entered Final Judgment on May 21, 2019 as well. Bard filed a second Notice of Appeal on May 23, 2019. Both appeals have since been consolidated and Bard’s opening brief was served on September 27, 2019 and the Company's answering brief is currently due on November 6, 2019. We maintain our belief that Bard’s claims are without merit and intends to defend them vigorously.merit.

EXECUTIVE OVERVIEW

Company and Market

We design, manufacture and sell a wide range of medical, surgical and diagnostic devices used by professional healthcare providers for vascular access, for the treatment of peripheral vascular disease and for use in oncology and surgical settings. Our devices are generally used in minimally invasive, image-guided procedures. MostMany of our products are intended to be used once and then discarded, or they may be temporarily implanted for short- or longer-term use.

Our business operations cross a variety of markets. Our financial performance is impacted by changing market dynamics, which have included an emergence of value-based purchasing by healthcare providers, consolidation of healthcare providers, the increased role of the consumer in health care decision-making and an aging population, among others. In addition, our growth is impacted by changes within our sector, such as the merging of competitors to gain scale and influence; changes in the regulatory environment for medical device; and fluctuations in the global economy.

Our sales and profitability growth also depends, in part, on the introduction of new and innovative products, together with ongoing enhancements to our existing products. Expansions to our product offerings are created through internal product development, technology licensing and strategic alliances. We recognize the importance of, and intend to continue to make investments in research and development activities and business development opportunities and feel confident that our existing capital structure and free cash flow generation will allow us to properly fund those activities. This was evident with the BioSentry and RadiaDyne acquisitions noted below.

On August 14, 2018, the Company acquired the BioSentry Tract Sealant System (BioSentry) technology from Surgical Specialties, LLC, a medical device company headquartered in Westwood, Massachusetts for a total purchase price of $39.8 million of which $37.0 million was paid on August 14, 2018 and $2.8 million was recorded as contingent consideration. The contingent consideration liability was recorded at fair value and will be payable to SSC upon fulfillment of certain hydrogel orders. This is part of the Company’s strategic focus on building a continuum of care within the oncology space. Refer to Note 2 for further disclosure on the acquisition.


On September 21, 2018, the Company acquired RadiaDyne, a privately held medical diagnostic and device company that designs and develops patient dose monitoring technology to improve cancer treatment outcomes. The aggregate purchase price of $75.0 million included an upfront payment of $47.9 million, contingent consideration with an estimated fair value of $22.3 million, an indemnification holdback of $4.6 million and a purchase price holdback of $0.2 million. The fair value of $22.3 million is comprised of $16.5 million for the revenue milestones and $5.8 million for the technical milestones. The $4.6 million indemnification holdback is recorded in other long-term liabilities and the $0.2 million purchase price holdback is recorded in accrued liabilities. This acquisition expands the Company’s growing Oncology business by adding RadiaDyne’s early-stage, proprietary OARtrac® real-time radiation dose monitoring platform and other market-leading oncology solutions, including the IsoLoc®/ImmobiLoc® and Alatus® balloon stabilizing technologies.
We sell our products in the United States primarily through a direct sales force, and outside the U.S. through a combination of a direct sales and distributor relationships. We expect our businesses to grow in both sales and profitability through geographic expansion, market penetration, new product introductions and increasing our direct presence internationally.

(“Medline”) pursuant to an asset purchase agreement dated April 17, 2019 (the “Asset Purchase Agreement”). Total consideration received

by the Company for the Divestiture in the fourth quarter of fiscal year 2019 was $169.2 million in cash and resulted in a gain of $46.6 million after working capital adjustments of $0.6 million. A portion of the net proceeds were used on June 3, 2019 to retire the outstanding balance on the Term Loan and Revolving Facility and the remaining net proceeds will continue to be invested in the business.

The BioSentry acquisition increased intangible assets by $26.0 million and resulted in additional amortization expense of $0.5 million. The RadiaDyne acquisition increased intangible assets by $25.6 million and resulted in additional amortization expense of $0.6 million.

Change in fair value of contingent consideration - Represents changes in contingent consideration driven by changes to estimated future payments on earn-out liabilities created through acquisitions and amortization of present value discounts on long-term contingent consideration.

The increasechange from the prior year is due to the gain of $0.6 million that was recorded on the technical milestones and revenue milestones for the RadiaDyne contingent considerations that were recorded as part consideration. This gain was partially offset by normal amortization

of the BioSentry and RadiaDyne acquisitions of $2.8 million and $22.3 million, respectively. The change in the fair value in contingent consideration is the result of amortization of the present value discount of $0.2$0.1 million. In addition, in the second quarter of fiscal year 2018, the final minimum payment of $1.2 million was made on the AngioVac product contingent consideration and a $2.1 million payment was made onpaid for the Microsulis contingent consideration during the first quarter of fiscal 2019.

Our effective tax rate including discrete items for the three month periods ended November 30,August 31, 2019 and 2018 was 8.3% and 2017 was 21.6% and negative (200.0)%17.7%, respectively. In fiscal 2019,2020, the Company'sCompany’s effective tax rate differs from the U.S. statutory rate primarily due to the impact of the valuation allowance, foreign taxes, and state taxes.other non-deductible permanent items (such as non-deductible meals and entertainment, Section 162(m) excess compensation and non-deductible stock based compensation).

The estimated annual effective tax rate, however, prior to discrete items was 26.3%8.3% in the secondfirst quarter of fiscal 2019,2020, as compared to 59.8%17.8% for the same period in fiscal 2018.

The Company regularly assesses its ability to realize its deferred tax assets. Assessing the realization of deferred tax assets requires significant management judgment. In determining whether its deferred tax assets are more likely than not realizable, the Company evaluated all available positive and negative evidence, and weighted the evidence based on its objectivity. Evidence the Company considered included its history of net operating losses, which resulted in the Company recording a full valuation allowance for its deferred tax assets in fiscal 2016, except the naked credit deferred tax liability.
Based on the review of all available evidence, the Company determined that it has not yet attained a sustained level of profitability and the objectively verifiable negative evidence outweighed the positive evidence. Therefore, the Company has provided a valuation allowance on its federal and state net operating loss carryforwards, federal and state R&D credit carryforwards and other net deferred tax assets that have a limited life and are not supportable by the naked credit deferred tax liability sourced income as of November 30, 2018. The Company will continue to assess the level of the valuation allowance required. If sufficient positive evidence exists in future periods to support a release of some or all of the valuation allowance, such a release would likely have a material impact on the Company’s results of operations.

Effective tax rate including discrete items 25.9% (219.4)%

Our effective tax rate including discrete items for the three month periods ended November 30, 2018 and 2017 was 25.9% and negative (219.4)%, respectively. In fiscal 2019, the Company's effective tax rate differs from the U.S. statutory rate primarily due to the impact of the valuation allowance, foreign taxes and state taxes.

Cash provided byused in operating activities

SixThree months ended November 30,August 31, 2019:

Net loss of $1.3 million plus the non-cash items, primarily driven by depreciation and amortization, contributed to cash used in operations of $6.5 million.
Working capital was negatively impacted by increased inventory on hand of $5.2 million and decreased accounts payable and accrued liabilities of $17.6 million. Accounts receivable had a favorable impact on working capital as a result of the sale of the Fluid Management business.

Three months ended August 31, 2018:

Net incomeloss was driven by increased sales and increased gross profit. This was partially offset by higher operating expenses in research and development, selling and marketing and general administrative as well as costs related to our acquisition and restructuring activities. Partially offsetting the higher operating expenses was an increase in gross profit.
The Company continues to focus on optimizing its cash conversion cycle. In the secondfirst quarter of fiscal year 2019 working capital was negatively impacted by increased inventory on hand of $1.0$0.8 million. Additionally, even though days sales outstanding ("DSO") decreasedincreased by two days receivables negatively impacted working capital by $3.1for a $0.6 million as a result of increased sales in the quarter.impact. Also, the $12.5 million DOJ settlement payment that was made during the first quarter of fiscal year 2019 negatively impacted working capital from accounts payable and accrued liabilities.

Six months ended November 30, 2017:

Net income was driven by higher sales and higher gross margins.
With regards to working capital, the Company focused on optimizing DSO which contributed to $2.3 million of working capital improvement. This working capital improvement was offset by a $4.5 million decrease in accounts payable and accrued liabilities.

Cash used in investing activities

SixThree months ended November 30, 2018August 31, 2019 and 2017:2018:

$1.4 million in fixed asset additions primarily for maintenance of equipment versus $1.2$0.7 million in the prior year.

term loans in an aggregate amount not to exceed $75.0 million.  We believe that our current cash and investment balances, together with future cash generated from operations and access to our revolving credit facility, capacity of up to $150.0 million as of November 30, 2018, will provide sufficient liquidity to meet our anticipated needs for capital for at least

the next 12 months. As part of the RadiaDyne acquisition that closed on September 21, 2018, the Company drew $55.0 million on the revolving credit facility. Based on our current leverage ratio of net debt to EBITDA, as defined by the Credit Agreement, the Company could draw approximately $85.0 million more on the remaining $95.0 million of the revolving credit facility. If we seek to make significant acquisitions of other businesses or technologies in the future for cash, we may require additional external financing.

Item 3.Quantitative and Qualitative Disclosures About Market Risk.

Foreign Currency Exchange Rate Risk

We are exposed to market risk from changes in currency exchange rates, as well as interest rate fluctuations on our credit facility and investments that could impact our results of operations and financial position.

We transact sales in currencies other than the U.S. Dollar, particularly the Euro, British pound and Canadian dollar. Approximately 8%7% of our sales in the secondfirst quarter of fiscal 20192020 were denominated in foreign currencies. We do not have expenses denominated in foreign currencies at the level of our sales and as a result, our profitability is exposed to currency fluctuations. When the U.S. Dollar strengthens, our sales and gross profit will be negatively impacted. In addition, we have assets and liabilities denominated in non-functional currencies which are remeasured at each reporting period, with the offset to changes presented as a component of Other (Expenses) Income. Significant non-functional balances include accounts receivable due from a sub-section of our international customers.

Interest Rate Risk

On November 7, 2016,June 3, 2019, we entered into the Credit Agreement which provides for a $100 million senior secured Term Loan and a $150$125 million Revolving Facility. Interest on both the Term Loan and Revolving Facility isfacility will be based, at the Company’s option, on a base rate or Eurodollar rateof LIBOR plus an applicable margin which increases as ourtied to the Company’s total leverage ratio increases, with theand having ranges between 0.25% and 0.75% for base rate loans and Eurodollar rate having ranges of 0.50% tobetween 1.25% and 1.50% to 2.25% respectively.1.75% for LIBOR loans. In the event of default, the interest rate may be increased by 2.0%. A 50 basis point (0.50%) increase or decrease in the interest rate would result approximately in a $2.0 million increase or decrease in interest expense over the life of the agreement.

Concentration of Credit Risk

Financial instruments, which potentially subject the Company to significant concentrations of credit risk, consist primarily of cash and cash equivalents, our credit facility and trade accounts receivable.

The Company maintains cash and cash equivalents at various institutions and performs periodic evaluations of the relative credit standings of these financial institutions to ensure their credit worthiness. In addition, the Credit Agreement is structured across five above investment grade banks. The Company has the ability to draw equally amongst the five banks which limits the concentration of credit risk of one institution.

Concentration of credit risk with respect to trade accounts receivable is limited due to the large number of customers that purchase products from the Company. No single customer represents more than 10% of total sales. The Company monitors the creditworthiness of its customers to which it grants credit terms in the normal course of business. Although the Company does not currently foresee a significant credit risk associated with the outstanding accounts receivable, repayment is dependent upon the financial stability of our customers.

Item 4.Controls and Procedures.

Evaluation of disclosure controls and procedures

As of the end of the period covered by this report, our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures pursuant to Rule 13a-15(b) of the Securities Exchange Act of 1934, as amended.

Changes in Internal Control over Financial Reporting

Item 1.Legal Proceedings.

C.R. Bard, Inc. v. AngioDynamics, Inc.

On January 11, 2012, C.R. Bard, Inc. (“Bard”) filed a suit in the United States District Court of Utah claiming certain of the Company's implantable port products infringe on three U.S. patents held by Bard (the "Utah Action"). Bard’s Complaintcomplaint sought unspecified damages and other relief. The Company filed petitions for reexamination in the US Patent and Trademark Office ("USPTO") seeking to invalidate all three patents asserted by Bard in the litigation. The Company's petitions were granted and 40 of Bard's 41 patent claims were rejected and, following further proceedings, the Patent Office issued a Final Rejection of all 4000040 claims subject to reexamination. Thereafter, Bard filed appeals to the USPTO Board of Appeals and Interferences for all three reexaminations. The Patent Office issued decisions in all three appeals.reexaminations which were decided as follows: In one (issued on March 11, 2016 for US Patent No. 7,785,302), the rejections of six of the ten claims under reexamination were affirmed, but were reversed on four of the ten claims. In the second (issued on March 24, 2016 for U.S. Patent No. 7,959,615), the rejections of eight of the ten claims under reexamination were affirmed but the rejections of the other two of the ten claims were reversed. In the third (issued on March 29 for U.S. Patent No. 7,947.022)7,947,022) the rejections of all twenty claims under reexamination were affirmed.

The PTO denied all three Rehearing Requests, - on February 1, 2017 for the ‘302; on February 17, 2017 for the ‘022; and on February 21, 2017 for the ‘615, but modified its characterization of one prior art reference for the ‘302 and ‘022 decisions. 

Bard filed a Notice of Appealappeals to the Federal Circuit Court of Appeals in all three reexams and the Company filed Cross-Appeals for the ‘302 and the ‘615 reexams. The parties havereexams and completed the process of filing the various appellate briefs.  MedCompbriefing.  Medcomp also filed an Amicus Brief in support of the Company on November 22, 2017.  An oral hearing in the case was held on September 5, 2018 and the courtCourt rendered its decision on September 28, 2018.  The Federal Circuit affirmed2018, affirming that claims 1-5 and 10 of the ‘615 patent were invalid.  The Federal Circuit also affirmed the Board’s decisioninvalid, but that claims 6-7 of the 615 patent and 1-4 of the 302 patent were valid in light ofover the asserted prior art references.references considered in the Reexamination proceedings.  The Federal Circuit also reversed the PTAB’s claim construction ruling and remanded for consideration of obviousness for the remaining claims under the new claim construction ruling and for further findings with respect to whether one of the asserted references qualified as a printed publication.  The parties are awaiting further instruction for proceeding fromOn January 28, 2019, on remand, the USPTO in lightreversed the rejections of the decision.  Meanwhile,‘302 claims 1-10, ‘022 claims 1-20 and ‘615 claims 6-9.  The USPTO has since issued Inter Partes Reexamination Certificates for the ‘302 Patent (confirming validity of claims 1-10) on June 10, 2019, and for the ‘022 patent (confirming validity of claims 1-20) on July 2, 2019, and for the ‘615 patent on August 26, 2019.   The Company has since filed a Motion to Unstay the Utah Action has been stayed pending final resolution ofCase; that motion is fully briefed and awaiting decision by the USPTO process.  OnUtah Court. Meanwhile, on July 12, 2017, Bard assigned the asserted patents to Bard Peripheral Vascular, Inc. (“BPV”) which was added as Co-Appellant before the Federal Circuit and as a co-Plaintiff in the Utah action.  The Company believes these claims are without merit and intends to defend them vigorously.  The Company has not recorded an expense related to the outcome of this litigation because it is not yet possible to determine if a potential loss is probable nor reasonably estimable.

On March 10, 2015, C.R. Bard Inc. ("Bard") and Bard Peripheral Vascular, Inc. (“BPV”)BPV filed suit in the United States District Court for the District of Delaware (the “Delaware Action") claiming certain of the Company's implantable port products infringe on three other U.S. patents held by Bard, (the “Delaware Action").which are different from those asserted in the Utah action. Bard's complaint seeks unspecified damages and other relief. The patents asserted in the Delaware Action are different than those asserted in the Utah Action. On June 1, 2015, the Company filed two motions in response to Bard’s Complaint - one sought transfer to the District of Utah where the Utah Action is currently pending, and the other sought dismissal of the entire complaint on grounds that none of the claims in the asserted patents is directed to patent eligible subject matter under Section 101 of the Patent Statute and in light of recent authority from the U. S. Supreme Court.

On January 12, 2016, the Court issued a decision denying both motions. A Markman hearing was held on March 10, 2017 and the Court issued its Claim Construction Order on May 19, 2017. On May 19, 2017, Bard served its Final Infringement Contentions and on June 2, 2017, the Company served its Final Invalidity Contentions.

On October 20, 2017, the scheduling order for the case was amended to, among other things, set a trial date commencing July 23, 2018. The parties completed Expert Discovery in January 2018. The parties2018 and completed briefing on their respective case dispositive motions on April 27, 2018. On June 26, 2018, the Court denied all case dispositive motions, ruling that issues of material fact remained in dispute. On July 9, 2018, the Court continued the trial until March 2019. Meanwhile, a further Markman hearing is scheduled forOn January 9, 2019 the Court held a further claim construction hearing to resolve two outstanding claim construction issues which are needed before the case goesprior to trial. TheA Report and Recommendation was issued on February 11, 2019 and entered by the Court on February 28, 2019. Jury selection was held on Friday March 1, 2019 and trial began on March 4, 2019.  On day four of the jury trial, at the close of C.R. Bard’s case (Plaintiff), Judge Bataillon granted judgment as a matter of law under rule 50(a) in favor of AngioDynamics, dismissing Bard’s

suit.  On April 5, 2019, Bard filed a precautionary Notice of Appeal to the Federal Circuit. On April 26, 2019, the District Court issued a Memorandum and Order confirming the grant of judgment in the Company’s favor of patent ineligibility, non-infringement, patent invalidity and no willful infringement. Meanwhile, on May 10, 2019, the Company believes thesefiled a Motion for Attorney fees and non-taxable expenses under 35 USC Sec. 285. On May 21, 2019, the Court issued a Memorandum and Order which, inter alia, stayed proceedings on the Company’s fee Motion and the Company’s equitable claims pending appeal; and entered Final Judgment on May 21, 2019 as well. Bard filed a second Notice of Appeal on May 23, 2019. Both appeals have since been consolidated and Bard’s opening brief was served on September 27, 2019 and the Company's answering brief is currently due on November 6, 2019. We maintain our belief that Bard’s claims are without merit and intends to defend them vigorously.merit.
