2. Summary of Significant Accounting Policies

(a)

Principles of Consolidation

The consolidated financial statements include the accounts of Harvard Bioscience, Inc. and its wholly-owned subsidiaries. All intercompany balances and transactions have been eliminated in consolidation.

(b)

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires the use of management estimates. Such estimates include the determination and establishment of certain accruals and provisions, including those for inventory excess and obsolescence, income tax and reserves for bad debts. In addition, certain estimates are required in order to determine the value of assets and liabilities associated with acquisitions, as well as the Company’s defined benefit pension obligations. Estimates are also required to evaluate the value and recoverability of existing long-lived and intangible assets, including goodwill. On an ongoing basis, the Company reviews its estimates based upon currently available information. Actual results could differ materially from those estimates.

(c)

Cash and Cash Equivalents

For purposes of the consolidated balance sheets and statements of cash flows, the Company considers all highly liquid instruments with original maturities of three months or less to be cash equivalents. Cash and cash equivalents include cash on hand and amounts due from banks. The Company maintains a portion of its cash in bank deposits, which at times, may exceed federally insured limits. The Company has not experienced any losses in such accounts. The Company does not believe it is exposed to any significant risk with respect to these accounts.

(d)

Allowance for Doubtful Accounts

The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The Company determines the allowance based on considering factors such as historical experience, credit quality, known troubled accounts, historical experience, factors that may affect a customer’s ability to pay and other currently available evidence.

(e)

Inventories

The Company values its inventories at the lower of the actual cost to purchase (first-in, first-out method) and/or manufacture the inventories or the net realizable value of the inventories. The Company regularly reviews inventory quantities on hand and records a provision to write down excess and obsolete inventories to its estimated net realizable value if less than cost, based primarily on historical inventory usage and estimated forecast of product demand.

(f)

Property, Plant and Equipment

Property, plant and equipment are stated at cost and depreciated using the straight-line method over the estimated useful lives of the assets as follows:

Buildings			40	years
Machinery and equipment	3	-	10	years
Computer equipment and software	3	-	7	years
Furniture and fixtures	5	-	10	years
Automobiles	3	-	6	years

Property and equipment held under capital leases and leasehold improvements are amortized using the straight line method over the shorter of the lease term or estimated useful life of the asset.

(g)

Catalog Costs

Significant costs of product catalog design, development and production are capitalized and amortized over the expected useful life of the catalog (usually one to three years).

(h)

Income Taxes

Income taxes are accounted for under the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to be applied to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

The Company recognizes the effect of income tax positions only if those positions are more likely than not of being sustained. Recognized income tax positions are measured at the largest amount that is more than 50% likely of being realized. Changes in recognition are reflected in the period in which the judgement occurs.

(i)

Foreign Currency Translation

The functional currency of the Company’s foreign subsidiaries is generally their local currency. All assets and liabilities of its foreign subsidiaries are translated at exchange rates in effect at period-end. Income and expenses are translated at rates which approximate those in effect on the transaction dates. The resulting translation adjustment is recorded as a separate component of stockholders’ equity in accumulated other comprehensive (loss) income (“AOCI”) in the consolidated balance sheets. Gains and losses resulting from foreign currency transactions are included in net (loss) income.

(j)

Earnings per Share

Basic earnings per share is computed by dividing net income by the weighted average number of shares of common stock outstanding during the periods presented. The computation of diluted earnings per share is similar to the computation of basic earnings per share, except that the denominator is increased for the assumed exercise of dilutive options and other potentially dilutive securities using the treasury stock method unless the effect is antidilutive. Since the Company is reporting discontinued operations, it used income from continuing operations as the control number in determining whether those potential dilutive securities are dilutive or antidilutive.

(k)

Comprehensive (Loss) Income

The Company follows the provisions of Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 220, “Comprehensive Income”. FASB ASC 220 requires companies to report all changes in equity during a period, resulting from net (loss) income and transactions from non-owner sources, in a financial statement in the period in which they are recognized. The Company has chosen to disclose comprehensive (loss) income, which encompasses net (loss) income, foreign currency translation adjustments, gains and losses on derivatives, the underfunded status of its pension plans, and pension minimum additional liability adjustments, net of tax, in the consolidated statements of comprehensive (loss) income.

(l)

Revenue Recognition

Nature of contracts and customers

The Company’s contracts are primarily of short duration and are mostly based on the receipt and fulfilment of purchase orders. The purchase orders are binding and include pricing and all other relevant terms and conditions.

The Company’s customers are primarily research scientists at pharmaceutical and biotechnology companies, universities, hospitals, government laboratories, including the United States National Institute of Health (NIH) and contract research organizations. The Company also has global and regional distribution partners, and original equipment manufacturer (OEM) customers who incorporate its products into their products under their own brands.

Performance obligations

The Company’s performance obligations under its revenue contracts consist of its instruments, equipment, accessories, services, maintenance and extended warranties. Equipment also includes software that functions together with the tangible equipment to deliver its essential functionality. Contracts with customers may contain multiple promises such as delivery of hardware, software, professional services or post-contract support services. These promises are accounted for as separate performance obligations if they are distinct. For contracts with customers that contain multiple performance obligations, the transaction price is allocated to the separate performance obligations based on estimated relative standalone selling price, which does not materially differ from the stated price in the contract. In general, the Company’s list prices are indicative of standalone selling price.

Instruments, equipment and accessories consist of a range of products that are used in life sciences research. Revenues from the sales of these items are recognized when transfer of control of these products to the customer occurs. Transfer of control occurs when the Company has a right to payment, and the customer has legal title to the asset and the customer or their selected carrier has possession, which is typically upon shipment. Sales on these items are therefore generally recognized at a point in time.

The Company’s equipment revenue also includes the sale of wireless implantable monitors that are used for life science research purposes. The Company sells these wireless implantable monitors to pharmaceutical companies, contract research organizations and academic laboratories. In addition to sales generated from new and existing customers, these implantable devices are also sold under a program called the “exchange program”. Under this program, customers may return an implantable monitor to the Company after use, and if the returned monitor can be reprocessed and resold, they may, in exchange, purchase a replacement implantable monitor of the same model at a lower price than a new monitor. The implantable monitors that are returned by customers are reprocessed and made available for future sale. The initial sale of implantable monitors and subsequent sale of replacement implantable monitors are independent transactions. The Company has no obligation in connection with the initial sale to sell replacement implantable monitors at any future date under any fixed terms and may refuse returned implantable monitors that cannot be recovered or are obsolete. The Company has concluded that the offer to its customers that they may purchase a discounted product in the future is not a material right based on the applicable guidance within ASC 606.

Service revenues consist of installation, training, data analysis, and surgeries performed on research animals. Maintenance revenue consists of post-contract support provided in relation to software that is embedded within the equipment that is sold to the customer. The Company provides standard warranties that promise the customer that the product will work as promised. These standard warranties are not a separate performance obligation. Extended warranties relate to warranties that are separately priced, and purchased in addition to a standard warranty, and are therefore a separate performance obligation. The Company has made the judgment that the customer benefits as the Company performs over the period of the contract, and therefore revenues from service, maintenance and warranty contracts are recognized over time. The Company uses the input method to recognize revenue over time, based on time elapsed, which is generally on a straight-line basis over the service period. The period over which maintenance and warranty contracts is recognized is typically one year. The period over which service revenues is recognized is generally less than one month.

For sales for which transfer of control occurs upon shipment, the Company accounts for shipping and handling costs as fulfilment costs. As such, the Company records the amounts billed to the customer for shipping costs as revenue and the costs within cost of revenues upon shipment. For sales, for which control transfers to customers after shipment, the Company has elected to account for shipping and handling as activities to fulfill the promise to transfer the goods to the customer. The Company therefore accrues for the costs of shipping undelivered items in the period of shipment.

Revenues expected to be recognized related to any and all remaining performance obligations are generally expected to be recognized in one year or less, as the majority of the Company's contracts have a term of less than one year.

Variable Consideration

The nature of the Company's contracts gives rise to certain types of variable consideration, including in limited cases volume and payment discounts. The Company analyzes sales that could include variable consideration, and estimates the expected or most likely amount of revenue after returns, trade-ins, discounts, rebates, credits, and incentives. Product returns are estimated and accrued for, based on historical information. In making these estimates, the Company considers whether the amount of variable consideration is constrained and is included in revenue only to the extent that it is probable that a significant reversal of the revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. Variable consideration, and its impact on the Company’s revenue recognition, was not material in any of the periods presented.

The Company’s payment terms are generally from zero to sixty days from the time of invoicing, which generally occurs at the time of shipment or prior to services being performed. Payment terms vary by the type of its customers and the products or services offered.

Sales taxes, value added taxes, and certain excise taxes collected from customers and remitted to governmental authorities are accounted for on a net basis, and are therefore excluded from revenues.

Deferred revenue

The Company records deferred revenue when cash is collected from customers prior to satisfaction of the Company’s performance obligation to the customer. Deferred revenue consists of amounts deferred related to service contracts and revenue deferred as a result of payments received in advance from customers. Deferred revenue is generally expected to be recognized within one year.

The amounts included in deferred revenue from advanced payments relate to amounts that are prepaid for wireless implantable monitors under the exchange program. The Company has made the judgment that these payments do not represent a significant financing component as the customer can exercise their discretion as to when they can obtain the products that they have made a prepayment for.

Advanced payments received from customers are recorded as a liability, and revenue is recognized when the Company’s performance obligations are completed. Performance obligations are completed when the product is shipped or delivered to the customer, or at the end of the exchange program if goods are not acquired prior to the termination of the contract period.

Disaggregation of revenue

Refer to Note 19 for revenue disaggregated by type and by geographic region as well as further information about the deferred revenue balances.

(m)

Valuation of Identifiable Intangible Assets Acquired in Business Combinations

The determination of the fair value of intangible assets, which represents a significant portion of the purchase price in the Company’s acquisitions, requires the use of significant judgment with regard to (i) the fair value; and (ii) whether such intangibles are amortizable or not amortizable and, if the former, the period and the method by which the intangibles asset will be amortized. The Company estimates the fair value of acquisition-related intangible assets principally based on projections of cash flows that will arise from identifiable assets of acquired businesses. The projected cash flows are discounted to determine the present value of the assets at the dates of acquisitions. At December 31, 2018, amortizable intangible assets include existing technology, trade names, distribution agreements, in-process research and development, customer relationships and patents. These amortizable intangible assets are amortized on a straight-line basis over 7 to 15 years, 10 to 15 years, 4 to 5 years, 5 to 15 years, 5 to 15 years and 5 to 15 years, respectively.

(n)

Goodwill and Other Intangible Assets

Goodwill and unamortizable intangible assets acquired in a business combination and determined to have an indefinite useful life are not amortized, but instead are tested for impairment annually or more frequently if events or changes in circumstances indicate that the asset might be impaired, in accordance with the provisions of FASB ASC 350, “Intangibles—Goodwill and Other”.

For the purpose of its goodwill analysis, the Company has one reporting unit. The Company conducted its annual impairment analysis in the fourth quarter of fiscal year 2018. The goodwill impairment test is a two-step process. The first step of the impairment analysis compares the Company’s fair value to its carrying value to determine if there is any indication of impairment. Step two of the analysis compares the implied fair value of goodwill to its carrying amount in a manner similar to a purchase price allocation for business combination. If the carrying amount of goodwill exceeds its implied fair value, an impairment loss is recognized equal to that excess. For indefinite-lived intangible assets if the carrying amount exceeds the fair value of the asset, the Company would write down the indefinite-lived intangible asset to fair value.

At December 31, 2018, the fair value of the Company significantly exceeded the carrying value. The Company concluded that none of its goodwill was impaired.

The Company evaluates indefinite-lived intangible assets for impairment annually and when events occur or circumstances change that may reduce the fair value of the asset below its carrying amount. Events or circumstances that might require an interim evaluation include unexpected adverse business conditions, economic factors, unanticipated technological changes or competitive activities, loss of key personnel and acts by governments and courts. At December 31, 2018, the Company concluded that none of its indefinite-lived intangible assets were impaired.

(o)

Impairment of Long-Lived Assets

The Company assesses recoverability of its long-lived assets that are held for use, such as property, plant and equipment and amortizable intangible assets in accordance with FASB ASC 360, “Property, Plant and Equipment” when events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets or an asset group to be held and used is measured by a comparison of the carrying amount of an asset or asset group to estimated undiscounted future cash flows expected to be generated by the asset or the asset group. Cash flow projections are based on trends of historical performance and management’s estimate of future performance. If the carrying amount of the asset or asset group exceeds the estimated future cash flows, an impairment charge is recognized by the amount by which the carrying amount of the asset or asset group exceeds its estimated fair value. At December 31, 2018, the Company concluded that none of its long-lived assets were impaired.

The Company uses interest-rate-related derivative instruments to manage its exposure related to changes in interest rates on its variable-rate debt instruments. The Company does not enter into derivative instruments for any purpose other than cash flow hedging. The Company does not speculate using derivative instruments. The Company recognizes all derivative instruments as either assets or liabilities in the balance sheet at their respective fair values. For derivatives designated in hedging relationships, changes in the fair value are either offset through earnings against the change in fair value of the hedged item attributable to the risk being hedged or recognized in AOCI, to the extent the derivative is effective at offsetting the changes in cash flows being hedged until the hedged item affects earnings.

The Company only enters into derivative contracts that it intends to designate as a hedge of a forecasted transaction or the variability of cash flows to be received or paid related to a recognized asset or liability (cash flow hedge). For all hedging relationships, the Company formally documents the hedging relationship and its risk-management objective and strategy for undertaking the hedge, the hedging instrument, the hedged transaction, the nature of the risk being hedged, how the hedging instrument’s effectiveness in offsetting the hedged risk will be assessed prospectively and retrospectively, and a description of the method used to measure ineffectiveness. The Company also formally assesses, both at the inception of the hedging relationship and on an ongoing basis, whether the derivatives that are used in hedging relationships are highly effective in offsetting changes in cash flows of hedged transactions. For derivative instruments that are designated and qualify as part of a cash flow hedging relationship, the effective portion of the gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment of effectiveness are recognized in current earnings.

The Company discontinues hedge accounting prospectively when it determines that the derivative is no longer effective in offsetting cash flows attributable to the hedged risk, the derivative expires or is sold, terminated, or exercised, the cash flow hedge is de-designated because a forecasted transaction is not probable of occurring, or management determines to remove the designation of the cash flow hedge.

In all situations in which hedge accounting is discontinued and the derivative remains outstanding, the Company continues to carry the derivative at its fair value on the balance sheet and recognizes any subsequent changes in its fair value in earnings. When it is probable that a forecasted transaction will not occur, the Company discontinues hedge accounting and recognizes immediately in earnings gains and losses that were accumulated in other comprehensive income related to the hedging relationship.

Fair Value of Financial Instruments

The carrying values of the Company’s cash and cash equivalents, trade accounts receivable and trade accounts payable and short-term debt approximate their fair values because of the short maturities of those instruments. The fair value of the Company’s long-term debt approximates its carrying value and is based on the amount of future cash flows associated with the debt discounted using current borrowing rates for similar debt instruments of comparable maturity.

Financial reporting standards define a fair value hierarchy that consists of three levels:



Level 1 includes instruments for which quoted prices in active markets for identical assets or liabilities accessible to the Company at the measurement date.



Level 2 includes instruments for which the valuations are based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities.



Level 3 includes valuations based on inputs that are unobservable and significant to the overall fair value measurement.

Stock-based Compensation

The Company accounts for stock-based payment awards in accordance with the provisions of FASB ASC 718, “Compensation—Stock Compensation”, which requires it to recognize compensation expense for all stock-based payment awards made to employees and directors including stock options, restricted stock units, and restricted stock units with a market condition related to our Third Amended and Restated 2000 Stock Option and Incentive Plan (as amended, the “Third A&R Plan”) as well as employee stock purchases (“employee stock purchases”) related to its Employee Stock Purchase Plan (as amended, the “ESPP”). The Company issues new shares upon stock option exercises, upon vesting of restricted stock units and restricted stock units with a market condition, and under the Company’s ESPP.

Stock-based compensation expense recognized is based on the value of the portion of stock-based payment awards that is ultimately expected to vest and has been reduced for estimated forfeitures. The Company values stock-based payment awards, except restricted stock units at grant date using the Black-Scholes option-pricing model (“Black-Scholes model”). The Company values restricted stock units with a market condition using a Monte-Carlo valuation simulation. The determination of fair value of stock-based payment awards on the date of grant using an option-pricing model or Monte-Carlo valuation simulation is affected by its stock price as well as assumptions regarding certain variables. These variables include, but are not limited to its expected stock price volatility over the term of the awards and actual and projected stock option exercise behaviors.

The fair value of restricted stock units are based on the market price of the Company’s stock on the date of grant and are recorded as compensation expense ratably over the applicable service period, which ranges from one to four years. Unvested restricted stock units are forfeited in the event of termination of employment with the Company.

Stock-based compensation expense recognized under FASB ASC 718 for the years ended December 31, 2018 and 2017 consisted of stock-based compensation expense related to stock options, the employee stock purchase plan, and the restricted stock units and was recorded as a component of cost of product revenues, sales and marketing expenses, general and administrative expenses, research and development expenses and discontinued operations. Refer to Note 14 for further details.

Recently Issued Accounting Pronouncements

In February 2016, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2016-02, Leases, which is intended to improve financial reporting about leasing transactions. The update requires a lessee to record on the balance sheet the assets and liabilities for the rights and obligations created by lease terms of more than 12 months. The update is effective for fiscal years beginning after December 15, 2018. A modified retrospective transition approach is required for leases existing at, or entered into after, the beginning of the earliest comparative period presented in the financial statements, with certain practical expedients available. The Company expects to utilize a practical expedient in its method of adoption of the standard. Under this expedient, which is a “current-period adjustment method,” the Company would apply ASC 842 as of January 2019 and record a cumulative-effect adjustment to retained earnings as of that date.

The Company has made substantial progress in its assessment over the impact of the standard and determined that the only material leases that it holds are building leases. Upon adoption of the standard, the Company preliminarily expects to record a right of use asset in the range of approximately $9 to $11 million and a lease liability in the range of approximately $10 to $12 million on its consolidated balance sheet. The finalization of the Company’s assessment may result in changes to the Company’s estimates that may impact its preliminary estimate of the cumulative effect. The Company’s future commitments under lease obligations are summarized in Note 13.

In June 2016, the FASB issued ASU No. 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, which amends the impairment model by requiring entities to use a forward-looking approach based on expected losses rather than incurred losses to estimate credit losses on certain types of financial instruments, including trade receivables. This may result in the earlier recognition of allowances for losses. The ASU is effective for public entities for fiscal years beginning after December 15, 2019, with early adoption permitted. In November 2018, the FASB issued ASU No. 2018-19, Codification Improvements to Topic 326, Financial Instruments—Credit Losses, which provided additional implementation guidance on the previously issued ASU. Management has not yet completed its assessment of the impact of the new standard on the Company’s consolidated financial statements. Currently, the Company believes that the most notable impact of this ASU will relate to its processes around the assessment of the adequacy of its allowance for doubtful accounts on trade accounts receivable and the recognition of credit losses.

In August 2017, the FASB issued ASU 2017-12, Derivatives and Hedging (Topic 815) which amends the hedge accounting recognition and presentation requirements in ASC 815, Derivatives and Hedging. The Board’s objectives in issuing the ASU are to (1) improve the transparency and understandability of information conveyed to financial statement users about an entity’s risk management activities by better aligning the entity’s financial reporting for hedging relationships with those risk management activities and (2) reduce the complexity of and simplify the application of hedge accounting by preparers. The ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2018. Early adoption is permitted, including adoption in any interim period. The Company is evaluating the requirements of this guidance and has not yet determined the impact of the adoption on its consolidated financial position, results of operations and cash flows.

In August 2018, the FASB issued ASU No. 2018-14, Disclosure Framework—Changes to the Disclosure Requirements for Defined Benefit Plans, which amends ASC 715 to add, remove and clarify disclosure requirements related to defined benefit pension and other postretirement plans. The ASU is effective for public entities for fiscal years beginning after December 15, 2020, with early adoption permitted. Management has not yet completed its assessment of the impact of the new standard on the Company’s Consolidated Financial Statements.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers, a new accounting standard that provides for a comprehensive model to use in the accounting for revenue arising from contracts with customers that will replace most existing revenue recognition guidance within generally accepted accounting principles in the United States. Under this standard, revenue will be recognized to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services.

The Company adopted this standard as of January 1, 2018 using the modified retrospective approach, and applied the guidance to contracts that were not completed at the date of adoption. The Company’s significant revenue streams currently consist primarily of product revenue transactions, service, maintenance and extended warranty transactions on certain product sales. The timing of recognizing revenues for these revenue streams did not materially change. Additionally, the adoption of ASU 2014-09 did not have a material impact on the Company’s financial position, results of operations, equity or cash flows as of the adoption date or for the year ended December 31, 2018. The Company’s updated revenue recognition policy is described in Note 2 and disaggregated revenue disclosures required under ASC 2014-09 are presented in Note 19.

In May 2017, the FASB issued ASU 2017-09, Stock compensation (Topic 718): Scope of modification accounting which amends the scope of modification accounting for share-based payment arrangements. The ASU provides guidance on the types of changes to the terms or conditions of share-based payment awards to which an entity would be required to apply modification accounting under ASC 718. Specifically, an entity would not apply modification accounting if the fair value, vesting conditions, and classification of the awards are the same immediately before and after the modification. The ASU is effective for annual reporting periods, including interim periods within those annual reporting periods, beginning after December 15, 2017. The Company adopted this guidance on January 1, 2018, and the new standard did not have a material impact on its consolidated financial position, results of operations and cash flows

(t) Reclassifications

As disclosed in Note 6, on January 22, 2018, the Company sold substantially all the assets of its operating subsidiary, Denville Scientific, Inc. (Denville). The sale of Denville represented a strategic shift that had a major effect on the Company’s operations and financial results. As such and pursuant to Accounting Standards Codification (ASC) 205-20 – Presentation of Financial Statements - Discontinued Operations, the operating results of Denville for the years ended December 31, 2018 and 2017 have been presented in discontinued operations in the consolidated statements of operations. Additionally, the assets and liabilities of Denville as of December 31, 2017 have been recast in the consolidated balance sheet and presented as held for sale. These reclassifications and adjustments had no effect on total amounts within the consolidated balance sheet, consolidated statements of operations and comprehensive income (loss), consolidated statements of cash flows for any of the periods presented.

Acquisitions Disclosure [Text Block]

5. Acquisition

On January 31, 2018, the Company acquired all of the issued and outstanding shares of Data Sciences International, Inc. (DSI), a Delaware corporation, for approximately $71.1 million. The Company funded the acquisition from its existing cash balances, excess proceeds from the Denville Transaction discussed in Note 6, and proceeds from the Financing Agreement discussed in Note 15.

DSI, a St. Paul, Minnesota-based life science research company, is a recognized leader in physiologic monitoring focused on delivering preclinical products, systems, services and solutions to its customers. Its customers include pharmaceutical and biotechnology companies, as well as contract research organizations, academic labs and government researchers. This acquisition diversifies the Company’s customer base into the biopharmaceutical and contract research organization markets.

The aggregate purchase price for this acquisition was allocated to tangible and intangible net assets acquired as follows:

		(in thousands)
Tangible assets	$	34,010
Liabilities assumed		(11,949)
Net assets		22,061

Total amortizable intangible assets		40,318
Deferred tax liabilities, net		(13,120)
Total goodwill and intangible assets, net of tax		49,063
Acquisition purchase price	$	71,124


Tangible assets and liabilities assumed, as referenced above, consist of the following:

Cash acquired	$	2,576
Accounts receivable, net		5,069
Inventories		11,512
Other current assets		810
Property, plant and equipment, net		3,574
Deferred income tax assets, net		10,469
Tangible assets	$	34,010

Accounts payable and accrued liabilities	$	6,001
Deferred revenue including customer advances		2,976
Other long term liabilities		2,972
Liabilities assumed	$	11,949

The allocation of the purchase price for DSI was based on estimates of the fair value of the net assets acquired and was subject to adjustment upon finalization of the valuation of the acquired intangible assets and the related deferred taxes. Measurements of these items inherently require significant estimates and assumptions. During the year ended December 31, 2018, the Company made adjustments to the preliminary allocation of the purchase price that was presented in the March 31, 2018 Form 10-Q. The adjustments consisted of an increase of $4.5 million to deferred tax liabilities; an increase of $3.1 million to goodwill; a decrease of $1.6 million to other long term liabilities; an increase of $1.5 million to property, plant and equipment, net; an increase of $0.6 million in accounts payable and accrued liabilities; and an increase of $0.6 million to the purchase price related to a net working capital adjustment. As of December 31, 2018, the Company has finalized the purchase price allocation for DSI.

The weighted-average amortization periods for definite-lived intangible assets acquired are 9.4 years for tradenames, 8.2 years for developed technology, 12.4 years for customer relationships and 7.4 years for in-process research and development assets. The weighted average amortization period for all definite-lived intangible assets acquired is 9.3 years.

Goodwill recorded as a result of the acquisition of DSI is not deductible for tax purposes.

The results of operations for DSI have been included in the Company’s consolidated financial statements from the date of acquisition. The revenues of DSI included in the Company’s consolidated statement of operations from the date of acquisition were approximately $42.6 million for the eleven-month period ended December 31, 2018. The net income of DSI included in the Company’s consolidated statement of operations for the same period was approximately $1.8 million. Included in DSI’s net income was a $3.8 million charge recognized in cost of revenues related to purchase accounting inventory fair value step up amortization. The total inventory fair value step up was recognized into cost of revenues over one inventory turn, or approximately five and a half months. Also included in net income of DSI is $4.0 million of intangible asset amortization expense and $0.6 million of additional depreciation related to a step up of fair value of property, plant and equipment, net.

The following consolidated pro forma information is based on the assumption that the acquisition of DSI occurred on January 1, 2017. Accordingly, the historical results have been adjusted to reflect amortization expense, interest expense and other purchase accounting adjustments that would have been recognized on such a pro forma basis. The pro forma information is presented for comparative purposes only and is not necessarily indicative of the financial position or results of operations which would have been reported had the Company completed the acquisition during these periods or which might be reported in the future.

12. Employee Benefit Plans

The Company sponsors profit sharing retirement plans for its U.S. employees, which includes employee savings plans established under Section 401(k) of the U.S. Internal Revenue Code (the “401(k) Plans”). The 401(k) Plans cover substantially all full-time employees who meet certain eligibility requirements. Contributions to the 401(k) Plans are at the discretion of management. For the years ended December 31, 2018 and 2017, the Company contributed approximately $0.5 million and $0.6 million, respectively, to the 401(k) Plans.

The Company’s subsidiary in the United Kingdom, Biochrom Limited maintains contributory, defined benefit or defined contribution pension plans for substantially all of its employees. In 2014, these defined benefit pension plans were closed to new employees, as well as closed to the future accrual of benefits for existing employees. The provisions of FASB ASC 715-20 require that the funded status of the Company’s pension plans be recognized in its balance sheet. FASB ASC 715-20 does not change the measurement or income statement recognition of these plans, although it does require that plan assets and benefit obligations be measured as of the balance sheet date. The Company has historically measured the plan assets and benefit obligations as of the balance sheet date.

The weighted average assumptions used in determining the net pension cost for these plans follows:

	Year Ended December 31,
	2018	2017

Discount rate	2.65%	2.43%
Expected return on assets	4.68%	3.86%

The discount rate assumptions used for pension accounting reflect the prevailing rates available on high-quality, fixed-income debt instruments with terms that match the average expected duration of the Company’s defined benefit pension plan obligations. The Company uses the iBoxx AA 15yr+ index, which matches the average duration of its pension plan liability of approximately 15 years. With the current base of assets in the pension plans, a one percent increase/decrease in the discount rate assumption would decrease/increase annual pension expense by approximately $9,000.

The Company’s mix of pension plan investments among asset classes also affects the long-term expected rate of return on plan assets. As of December 31, 2018, the Company’s actual asset mix approximated its target mix. Differences between actual and expected returns are recognized in the calculation of net periodic pension (income)/cost over the average remaining expected future working lifetime, which is approximately 15 years, of active plan participants. With the current base of assets, a one percent increase/decrease in the asset return assumption would decrease/increase annual pension expense by approximately $178,000.

The fair value and asset allocations of the Company’s pension benefits as of December 31, 2018 and 2017 measurement dates were as follows:

		December 31,

Other		452	3%		453	3%
Total	$	17,819	100%	$	19,972	100%

Financial reporting standards define a fair value hierarchy that consists of three levels. The fair values of the plan assets by fair value hierarchy level as of December 31, 2018 and 2017 is as follows:

		December 31,
		2018		2017
		(in thousands)
Quoted Prices in Active Markets for Identical Assets (Level 1)	$	618	$	856
Significant Other Observable Inputs (Level 2)		17,201		19,116
Significant Other Unobservable Inputs (Level 3)		-		-
Total	$	17,819	$	19,972

Level 1 assets consist of cash and cash equivalents held in the pension plans at December 31, 2018. The Level 2 assets primarily consist of investments in private investment funds that are valued using the net asset values provided by the trust or fund, including an insurance contract. Although these funds are not traded in an active market with quoted prices, the investments underlying the net asset value are based on quoted prices

The Company expects to contribute at least $0.7 million to its pension plans during 2019. These contributions are expected to increase in 2019 and beyond by an immaterial amount in order to accelerate the deficit recovery period.

The benefits expected to be paid from the pension plans are $0.6 million in 2019, $0.5 million in 2020, $0.5 million in 2021, $0.6 million in 2022 and $0.7 million in 2023. The expected benefits to be paid in the five years from 2024—2028 are $4.0 million. The expected benefits are based on the same assumptions used to measure the Company’s benefit obligation at December 31, 2018.

Common Stock

On February 5, 2008, the Company’s Board of Directors adopted a Shareholder Rights Plan and declared a dividend distribution of one preferred stock purchase right for each outstanding share of the Company’s common stock to shareholders of record as of the close of business on February 6, 2008. These rights were not initially exercisable and would trade with the shares of the Company’s common stock. The rights would become exercisable under various conditions according to the terms of the plan. The Shareholder Rights Plan expired, with no rights having become exercisable, in accordance with its terms on the close of business on February 6, 2018.

Preferred Stock

The Company’s Board of Directors has the authority to issue up to 5.0 million shares of preferred stock and to determine the price privileges and other terms of the shares. The Board of Directors may exercise this authority without any further approval of stockholders. As of December 31, 2018, the Company had no preferred stock issued or outstanding.

Employee Stock Purchase Plan (as amended, the ESPP)

In 2000, the Company approved the ESPP. Under this ESPP, participating employees can authorize the Company to withhold a portion of their base pay during consecutive six-month payment periods for the purchase of shares of the Company’s common stock. At the conclusion of the period, participating employees can purchase shares of the Company’s common stock at 85% of the lower of the fair market value of the Company’s common stock at the beginning or end of the period. Shares are issued under the ESPP for the six-month periods ending June 30 and December 31. On May 18, 2017, the stockholders of the Company approved an increase of 300,000 shares of common stock in the number of shares available for issuance under the ESPP. Following such amendment, 1,050,000 shares of common stock are authorized for issuance, of which 890,762 shares were issued as of December 31, 2018. There were 89,308 and 76,215 shares issued under the ESPP during the years ended December 31, 2018 and 2017, respectively.

Stock Option and Equity Incentive Plans

Third Amended and Restated 2000 Stock Option and Incentive Plan (as amended, the Third A&R Plan)

The Third Amendment to the Third A&R Plan (the Amendment) was adopted by the Board of Directors on April 2, 2018. Such Amendment was approved by the stockholders at the Company’s 2018 Annual Meeting of Stockholders. Pursuant to the Amendment, the aggregate number of shares authorized for issuance under the Third A&R Plan was increased by 3,400,000 shares to 20,908,929.

Restricted Stock Units with a Market Condition (the Market Condition RSUs)

On August 3, 2015, the Compensation Committee of the Board of Directors of the Company approved and granted deferred stock awards of Market Condition RSUs (the 2015 Market Condition RSUs) to certain members of the Company’s management team under the Third A&R Plan. The vesting of these 2015 Market Condition RSUs was cliff-based and linked to the achievement of a relative total shareholder return of the Company’s common stock from August 3, 2015 to the earlier of (i) August 3, 2018 or (ii) upon a change of control (measured relative to the Russell 3000 index and based on the 20-day trading average price before each such date). As of August 3, 2018, certain of the target total shareholder returns were achieved, and as a result, 69,667 of the 2015 Market Condition RSUs vested. The remaining 2015 Market Condition RSUs did not vest and were canceled.

On May 24, 2018, the Compensation Committee of the Board of Directors of the Company approved and granted deferred stock awards of Market Condition RSUs (the 2018 Market Condition RSUs) to certain members of the Company’s management team under the Third A&R Plan. The vesting of the 2018 Market Condition RSUs is based on a graded-vesting schedule (one third at the end of each year for three years) and linked to the achievement of a relative total shareholder return of the Company’s common stock from May 24, 2018 to the earlier of (i) May 24, 2019 or (ii) upon a change of control (measured relative to the NASDAQ Biotechnology index and based on the 20-day trading average price before each such date). As of December 31, 2018, the target number of these restricted stock units that may be earned is 116,944 shares; the maximum amount is 150% of the target number.

Stock-Based Payment Awards

The Company accounts for stock-based payment awards in accordance with the provisions of FASB ASC 718, which requires it to recognize compensation expense for all stock-based payment awards made to employees and directors including stock options, restricted stock units, Market Condition RSUs and employee stock purchases related to the ESPP.

The Company adopted ASU 2016-09 as of January 1, 2017. As a result of this adoption, the Company has elected as an accounting policy to account for forfeitures for service based awards as they occur, with no adjustment for estimated forfeitures. The Company recognized as of January 1, 2017, a cumulative effect adjustment of $0.1 million to reduce retained earnings as required under the modified retrospective approach.

Earnings per share

Basic earnings per share is based upon net income divided by the number of weighted average common shares outstanding during the period. The calculation of diluted earnings per share assumes conversion of stock options, restricted stock units and Market Condition RSUs into common stock using the treasury method. The weighted average number of shares used to compute basic and diluted earnings per share consists of the following:

	Year Ended
	December 31,
	2018	2017

Basic	36,453,126	34,753,325
Effect of assumed conversion of employee and director stock options, restricted stock units and Market Condition RSUs	-	-
Diluted	36,453,126	34,753,325

Excluded from the shares used in calculating the diluted earnings per common share in the above table are options, restricted stock units and Market Condition RSUs of approximately 3,307,438 and 5,741,298 shares of common stock for the years ended December 31, 2018 and 2017, respectively, as the impact of these shares would be anti-dilutive.

The Company’s policy is to issue stock available from its registered but unissued stock pool through its transfer agent to satisfy stock option exercises and vesting of the restricted stock units.

The aggregate intrinsic value in the preceding table represents the total pre-tax intrinsic value, based on the Company’s closing stock price of $3.18 as of December 31, 2018, which would have been received by the option holders had all option holders exercised their options as of that date. The aggregate intrinsic value of options exercised for the years ended December 31, 2018 and 2017 was approximately $2.6 million and $0.1 million, respectively. The total number of in-the-money options that were exercisable as of December 31, 2018 was 160,851.

For the year ended December 31, 2018, the total compensation costs related to unvested awards not yet recognized is $3.2 million and the weighted average period over which it is expected to be recognized is 2.12 years.

The weighted-average estimated fair value per share of stock options granted during 2018 and 2017 was $1.83 and $1.32, respectively, using the Black Scholes option-pricing model with the following weighted-average assumptions:

	Year Ended

Dividend yield	-	%	-	%

The weighted average fair value of the 2018 Market Condition RSUs which were granted under the Third A&R Plan during the year ended December 31, 2018 was $4.19. There were no Market Condition RSUs granted during the year ended December 31, 2017. The following assumptions were used to estimate the fair value, using a Monte-Carlo valuation simulation, of the Market Condition RSUs granted during the year ended December 31, 2018:

	Year Ended
	December 31,
	2018
Volatility	44.02	%
Risk-free interest rate	2.27	%
Correlation coefficient	0.07	%
Dividend yield	-	%

The Company used historical volatility to calculate the expected volatility as of December 31, 2018. Historical volatility was determined by calculating the mean reversion of the daily adjusted closing stock price. The risk-free interest rate assumption is based upon observed U.S. Treasury bill interest rates (risk-free) appropriate for the term of the Company’s stock options. The expected holding period of stock options represents the period of time options are expected to be outstanding and were based on historical experience. The vesting period ranges from one to four years and the contractual life is ten years.

Stock-based compensation expense recognized in the consolidated statements of operations for the years ended December 31, 2018 and 2017 is recognized on awards as they vest and following the adoption of ASU 2016-09 in January 2017, is not reduced for annualized estimated forfeitures

15. Long Term Debt

On January 22, 2018, in connection with the closing of the Denville Transaction, the Company terminated the Third Amended and Restated Credit Agreement (the Credit Agreement), among the Company, Brown Brothers Harriman & Co. and each of the other lenders party thereto, and Bank of America, as administrative agent. All outstanding amounts under the agreement were repaid in full using a portion of the proceeds of the Denville Transaction. At the time of repayment, there was approximately $11.9 million outstanding.

On January 31, 2018, the Company entered into a financing agreement by and among the Company and certain subsidiaries of the Company parties thereto, as borrowers (collectively, the Borrower), certain subsidiaries of the Company parties thereto, as guarantors, various lenders from time to time party thereto (the Lenders), and Cerberus Business Finance, LLC, as collateral agent and administrative agent for the Lenders (the Financing Agreement). On August 16, 2018, the Company and Cerberus Business Finance, LLC entered into a First Amendment to the Financing Agreement, which such amendment modified certain provisions related to the borrowing base and reporting, among other things.

The Financing Agreement provides for senior secured credit facilities (the Senior Secured Credit Facilities) comprised of a $64.0 million term loan and up to a $25.0 million revolving line of credit. The proceeds of the term loan and $4.8 million of advances under the revolving line of credit were used to fund a portion of the DSI acquisition, and to pay fees and expenses related thereto and the closing of the Senior Secured Credit Facilities. In addition, the revolving facility is available for use by the Company and its subsidiaries for general corporate and working capital needs, and other purposes to the extent permitted by the Financing Agreement. The Senior Secured Credit Facilities have a maturity of five years.

Commencing on March 31, 2018, the outstanding term loans amortized in equal quarterly installments equal to $0.4 million per quarter on such date and during each of the next three quarters thereafter. Beginning the quarter ending March 31, 2019, the term loans amortize in installments of $0.6 million per quarter, continuing for the next three quarters thereafter and $0.8 million per quarter thereafter, with a balloon payment at maturity.

The obligations under the Senior Secured Credit Facilities are unconditionally guaranteed by the Company and certain of the Company’s existing and subsequently acquired or organized subsidiaries. The Senior Secured Credit Facilities and related guarantees are secured on a first-priority basis (subject to certain liens permitted under the Financing Agreement) by a lien on substantially all the tangible and intangible assets of the Company and its subsidiary guarantors, including all of the capital stock held by such obligors (subject to a 65% limitation on pledges of capital stock of foreign subsidiaries), subject to certain exceptions.

Interest on all loans under the Senior Secured Credit Facilities is paid monthly. Borrowings under the Financing Agreement accrue interest at a per annum rate equal to London Interbank Offered Rate (LIBOR) rate plus 6.25%. The loans are also subject to a 1.25% interest rate floor for LIBOR loans and a 4.25% interest rate floor for base rate loans.

The Financing Agreement contains customary representations and warranties and affirmative covenants applicable to the Company and its subsidiaries and also contains certain restrictive covenants, including, among others, limitations on the incurrence of additional debt, liens on property, acquisitions and investments, loans and guarantees, mergers, consolidations, liquidations and dissolutions, asset sales, dividends and other payments in respect of the Company’s capital stock, prepayments of certain debt, transactions with affiliates and modifications of organizational documents, material contracts, affiliated practice agreements and certain debt agreements. The Financing Agreement also contains customary events of default. As of December 31, 2018, the Company was in compliance with all financial covenants contained in the Financing Agreement, was subject to covenant and working capital borrowing restrictions and had available borrowing capacity under its Financing Agreement of $9.8 million.

As of December 31, 2018 and December 31, 2017, the Company had borrowings net of debt issuance costs of $60.8 million and $11.7 million respectively, outstanding. The carrying value of the debt approximates fair value because the interest rate under the obligation approximates market rates of interest available to the Company for similar instruments.

As of December 31, 2018, the weighted effective interest rate, net of the impact of the Company’s interest rate swap, on its term loan was 8.88%.

As of December 31, 2018 and December 31, 2017, the Company’s borrowings were comprised of:

Derivative Instruments and Hedging Activities Disclosure [Abstract]

Derivative Instruments and Hedging Activities Disclosure [Text Block]

16. Derivatives

By using derivative financial instruments to hedge exposures to changes in interest rates, the Company exposes itself to credit risk and market risk. Credit risk is the failure of the counterparty to perform under the terms of the derivative contract. When the fair value of a derivative contract is positive, the counterparty owes the Company, which creates credit risk for the Company. When the fair value of a derivative contract is negative, the Company owes the counterparty and, therefore, the Company is not exposed to the counterparty’s credit risk in those circumstances. The Company minimizes counterparty credit risk in derivative instruments by entering into transactions with carefully selected major financial institutions based upon their credit profile.

Market risk is the adverse effect on the value of a derivative instrument that results from a change in interest rates. The market risk associated with interest-rate contracts is managed by establishing and monitoring parameters that limit the types and degree of market risk that may be undertaken.

The Company assesses interest rate risk by continually identifying and monitoring changes in interest rate exposures that may adversely impact expected future cash flows and by evaluating hedging opportunities. The Company maintains risk management control systems to monitor interest rate risk attributable to both the Company’s outstanding or forecasted debt obligations as well as the Company’s offsetting hedge positions. The risk management control systems involve the use of analytical techniques, including cash flow sensitivity analysis, to estimate the expected impact of changes in interest rates on the Company’s future cash flows.

The Company uses variable-rate LIBOR debt to finance its operations. The debt obligations expose the Company to variability in interest payments due to changes in interest rates. Management believes that it is prudent to limit the variability of a portion of its interest payments. To meet this objective, management enters into LIBOR based interest rate swap agreements to manage fluctuations in cash flows resulting from changes in the benchmark interest rate of LIBOR. These swaps change the variable-rate cash flow exposure on the debt obligations to fixed cash flows. Under the terms of the interest rate swaps, the Company receives LIBOR based variable interest rate payments and makes fixed interest rate payments, thereby creating the equivalent of fixed-rate debt for the notional amount of its debt hedged.

As disclosed in Note 15, on January 31, 2018, the Company entered into a Financing Agreement comprised of a $64.0 million term loan and up to a $25.0 million revolving line of credit. Shortly after entering into this Financing Agreement, the Company entered into an interest rate swap contract with PNC Bank with a notional amount of $36.0 million and a termination date of January 1, 2023 in order to hedge the risk of changes in the effective benchmark interest rate (LIBOR) associated with the Company’s Term Loan. The swap contract converted specific variable-rate debt into fixed-rate debt and fixed the LIBOR rate associated with a portion of the term loan under the Financing Agreement at 2.72%. The interest rate swap was designated as a cash flow hedge instrument in accordance with ASC 815 “Derivatives and Hedging”.

The notional amount of the Company’s derivative instruments as of December 31, 2018 was $34.1 million.

The following table presents the notional amount and fair value of the Company’s derivative instruments as of December 31, 2018 and December 31, 2017.


				December 31, 2018

Interest rate swaps		Other assets (long term liabilities)	$	11,900	$	37

	(a) See Note 17 for the fair value measurements related to these financial instruments.

All of the Company’s derivative instruments are designated as hedging instruments.

The Company has structured its interest rate swap agreements to be 100% effective and as a result, there was no impact to earnings resulting from hedge ineffectiveness. Changes in the fair value of interest rate swaps designated as hedging instruments that effectively offset the variability of cash flows associated with variable-rate, long-term debt obligations are reported in accumulated other comprehensive income (AOCI). These amounts subsequently are reclassified into interest expense as a yield adjustment of the hedged interest payments in the same period in which the related interest affects earnings. The Company’s interest rate swap agreement was deemed to be fully effective in accordance with ASC 815, and, as such, unrealized gains and losses related to these derivatives were recorded as AOCI.

The following table summarizes the effect of derivatives designated as cash flow hedging instruments and their classification within comprehensive loss for the years ended December 31, 2018 and 2017:

Derivatives in Hedging Relationships	Amount of loss recognized in OCI on derivative (effective portion)
	Year Ended December 31,
	2018		2017

Interest rate swaps	$	(343)	$	(24)

The following table summarizes the reclassifications out of accumulated other comprehensive loss for the year ended December 31, 2018 and 2017:

	Year Ended December 31,				Location of amount reclassified from AOCI
	2018		2017		into income (effective portion)

Interest rate swaps	$	136	$	61	Interest expense, net

As of December 31, 2018, $61 thousand of deferred losses on derivative instruments accumulated in AOCI are expected to be reclassified to earnings during the next twelve months. Transactions and events expected to occur over the next twelve months that will necessitate reclassifying these derivatives’ losses to earnings include the repricing of variable-rate debt. As a result of terminating the Credit Agreement, as discussed in Note 15, the Company unwound its previous May 2017 interest rate swap contract and received $0.1 million in proceeds.

17. Fair Value Measurements

Fair value measurement is defined as the price that would be received to sell an asset or paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants at the measurement date. A fair value hierarchy is established, which prioritizes the inputs used in measuring fair value into three broad levels as follows:

Level 1—Quoted prices in active markets for identical assets or liabilities.

Level 2—Inputs, other than the quoted prices in active markets, that are observable either directly or indirectly.

Level 3—Unobservable inputs based on the Company’s own assumptions.

The following tables present the fair value hierarchy for those assets or liabilities measured at fair value on a recurring basis:

	Fair Value as of December 31, 2018
(In thousands)		Level 1		Level 2		Level 3		Total
Assets (Liabilities):
Interest rate swap agreements	$	-	$	(170)	$	-	$	(170)

(In thousands)		Level 1		Level 2		Level 3		Total
Assets (Liabilities):
Interest rate swap agreements	$	-	$	37	$	-	$	37

The Company uses the market approach technique to value its financial liabilities. The Company’s financial assets and liabilities carried at fair value include derivative instruments used to hedge the Company’s interest rate risks. The fair value of the Company’s interest rate swap agreements was based on LIBOR yield curves at the reporting date.

Income Taxes

Income Tax [Abstract]

Income Taxes Disclosure [Text Block]

20. Income Tax

Income tax from continuing operations was a benefit of approximately $3.7 million and $0.6 million for the years ended December 31, 2018 and 2017, respectively. The effective tax rate on continuing operations was 46.1% for the year ended December 31, 2018 compared with 23.1% for the same period in 2017. The difference between the Company’s effective tax rate year over year was primarily attributable to lower pre-tax income at certain individual subsidiaries in 2018 versus the impact of certain provisions of U.S tax reform in 2017.

On December 22, 2017, tax reform legislation known as the Tax Cuts and Jobs Act (the Tax Act) was signed into law. A majority of the provisions of the Tax Act are effective January 1, 2018. The Tax Act makes broad and complex changes to the U.S. Internal Revenue Code which include, but are not limited to: (1) the reduction of the corporate income tax rate from 35% to 21%; (2) the implementation of a modified territorial tax system with a one-time transition tax on previously unremitted earnings of foreign subsidiaries; (3) a new provision designed to tax global intangible low-taxed income (GILTI); (4) the deduction for foreign-derived intangible income (FDII); (5) a new limitation on deductible interest expense; and (6) limitations on the deductibility of certain executive compensation. In response to the Tax Act, the SEC issued Staff Accounting Bulletin No. 118 (SAB 118), which provided companies with a one-year measurement period to complete the accounting for the tax effects of the Tax Act. The end of the measurement period for purposes of SAB 118 was December 22, 2018. The Company has completed the analysis in accordance with guidance available as of the date of this filing and has recorded the impact as explained below.

At December 31, 2017, the impact of the remeasurement of deferred tax assets and liabilities from 35% to 21% was an expense of $3.2 million which was fully offset by a change in the valuation allowance. The 2017 U.S. tax impact of the one-time transition tax on the mandatory deemed repatriation of foreign earnings was an expense of $3.0 million. This impact was fully offset with net operating loss carryforwards for which a full valuation allowance had been recorded. As a result, no tax expense was recorded. In finalizing its analysis in 2018 the Company recorded an immaterial amount of adjustments to the original provisional amounts. With respect to GILTI, the Company has adopted a policy to account for this provision as a period cost.

For the year ended December 31, 2018, an income tax benefit of $0.4 million was recorded for discontinued operations. For the year ended December 31, 2017, income tax benefit for discontinued operations was $0.6 million.

Income tax expense attributable to income from continued operations for years ended December 31, 2018 and 2017 consisted of:

As of December 31, 2018 and 2017, the Company maintained a total valuation allowance of $13.9 million and $11.4 million, respectively, which relates to foreign, federal, and state deferred tax assets in both years. The valuation allowance is based on estimates of taxable income in each of the jurisdictions in which we operate and the period over which our deferred tax assets will be recoverable. The movement in the valuation allowance is primarily due to the finalization of purchase accounting for the DSI acquisition and its impact on the valuation allowance related to certain U.S. deferred tax assets.

The Company adopted the provisions of ASU 2016-09, Improvements to Employee Share-based Payment Accounting, on January 1, 2017. Upon adoption, the company recorded previously unrecognized excess tax benefits from the exercise of employee stock options as an increase in its deferred tax asset for net operating losses of approximately $0.5 million. The tax benefit of this increased deferred tax asset is fully offset by an increase in the valuation allowance. Following adoption, excess tax benefits or tax deficit is reflected as income tax benefit or expense in the year the tax impact is generated. Prior to the adoption of ASU 2016-09, these excess tax benefits could only be recognized when the related tax deduction reduces income taxes payable and the benefit would be reflected as a credit to additional paid-in capital if realized.

At December 31, 2018, the Company had federal net operating loss carryforwards of $27.2 million, a portion of which ($21.9 million) expires between 2019 and 2037; the remainder have an unlimited carryforward period. The Company’s state net operating loss carryforwards of $17.5 million expire between 2019 and 2037. The Company has foreign tax credits of $0.2 million which begin to expire in 2020, as well as $8.6 million of research and development tax credit carryforwards which begin to expire in 2020. Approximately $1.0 million of the research and development tax credit carryforwards are offset by a reserve for uncertain tax positions. The Company had $0.8 million of alternative minimum tax credit carryforwards which are not subject to expiration and become refundable under the Tax Act beginning in 2018. In addition, the Company had a total of $3.8 million of state investment tax credit carryforwards, research and development tax credit carryforwards, and EZ credit carryforwards, which begin to expire in 2019. The Internal Revenue Code (IRC) limits the amounts of net operating loss carryforwards or credits that a company may use in any one year in the event of a change in ownership under IRC Sections 382 or 383. As a result of the DSI acquisition as well as acquisitions in prior years, certain losses and carryforwards would be subject to such limitation. The Company has provided a full or partial valuation allowance for the portion of state NOLs and federal and state credit carryforwards the Company expects to expire before use.

As of December 31, 2018 and December 31, 2017, cash and cash equivalents held by the Company’s foreign subsidiaries was $3.2 million and $4.8 million, respectively. As of December 31, 2017, the Company changed its indefinite reinvestment assertion to provide that all foreign cash balances above the level required for local operating expenses would be repatriated to the U.S. in tax years after 2017. The Company maintains this modified assertion at December 31, 2018. As a result of the 2017 Tax Act, post-2017 dividends from qualifying Controlled Foreign Corporations are no longer taxed in the U.S. However, any dividends to the U.S. must still be assessed for withholding tax liability as well as state income tax liability. As a result of the Company’s assertion, the Company determined the potential state income tax liability related to available cash balances at foreign subsidiaries to be immaterial in 2018 and 2017. In addition, an accrued withholding tax liability of $38 thousand was recorded as of both December 31, 2018 and December 31, 2017, related to amounts determined to be available for repatriation.

At December 31, 2018 and 2017 the amount of unrecognized tax benefits that would affect the Company’s effective tax rate are shown in the table below:

		(in thousands)
Balance at December 31, 2016	$	406

Settlements		(30)

Balance at December 31, 2018	$	1,860

In 2017, a German income tax audit was settled for $30 thousand. In 2018, the Company recorded a reserve of $0.2 million related to upcoming audits. Additionally, reserves of $1.4 million were recorded to purchase accounting based on tax positions of acquired entities, including $0.8 million for credits and $0.5 million related to state income tax issues.

The Company anticipates that the total unrecognized tax benefits will be reduced within the next 12 months by approximately $0.5 million due to the expected settlement of certain positions of acquired entities. The Company classifies interest and penalties related to unrecognized tax benefits as a component of income tax expense. At December 31, 2018 and at December 31, 2017, the Company had accrued interest and penalties of $0.1 million and $15 thousand respectively. During 2018 and 2017, the Company recognized a net expense of $31 thousand and $5 thousand, respectively, for interest and penalties in its total tax provision.

The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, and various states and foreign jurisdictions. With few exceptions, the Company is no longer subject to income tax examinations by tax authorities in foreign jurisdictions for years before 2014. In the U.S., the Company's net operating loss and tax credit carryforward amounts remain subject to federal and state examination for tax years starting in 2000 as a result of tax losses incurred in prior years. There are currently no pending federal or state tax examinations. The Company is subject to audits by various taxing jurisdictions. At December 31, 2018, the Company received notice of income tax examinations to begin in 2019 at foreign subsidiaries for which reserves have been recorded.
