NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1 — BASIS OF PRESENTATION

The accompanying unaudited condensed consolidated financial statements have been prepared by Luminex Corporation (the Company or Luminex) in accordance with United States generally accepted accounting principles (U.S. GAAP) for interim financial information and the rules and regulations of the Securities and Exchange Commission (SEC). Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. The condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All significant intercompany accounts and transactions have been eliminated in consolidation. In the opinion of management, all adjustments (consisting of normal recurring entries) considered necessary for a fair presentation have been included. Operating results for the three and six months ended March 31,June 30, 2017 are not necessarily indicative of the results that may be expected for the year ending December 31, 2017. These financial statements should be read in conjunction with the financial statements and notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2016 (the 2016 10-K).

NOTE 2 — REORGANIZATION

Following the acquisition of Nanosphere, Inc. (Nanosphere) which occurred June 30, 2016, and to better focus on the Company's core business, the Company conducted a reorganization in December 2016. The reorganization included a headcount reduction of approximately 40 people, a reallocation of responsibilities within the research and development organization and a significant reduction of biodefense efforts.  The Company measured and accrued the liabilities associated with employee separation costs at fair value as of the date the plan was announced and terminations were communicated to employees, which primarily consisted of severance pay and other employee separation costs such as outplacement services and benefits. As a result of the organizational change, the Company eliminated approximately 4% of its aggregate workforce. The Company recognized a charge of approximately $2.5 million in the fourth quarter of 2016 in conjunction with these activities.

The remaining employee separation payments were paid in January 2017. As such, there is no remaining liability within accrued liabilities on the consolidated balance sheet as of March 31, 2017.



NOTE 32 — INVESTMENTS

Marketable Securities

The Company determines the appropriate classification of its investments in debt and equity securities at the time of purchase and re-evaluates such determinations at each balance sheet date. Marketable securities that are bought and held principally for the purpose of selling them in the near term are classified as trading securities and are reported at fair value, with unrealized gains and losses recognized in earnings. Debt securities are classified as held-to-maturity when the Company has the positive intent and ability to hold the securities to maturity. Held-to-maturity securities are stated at amortized cost, which approximates the fair value of these investments. Debt securities for which the Company does not have the intent or ability to hold to maturity are classified as available-for-sale. Debt and marketable equity securities not classified as held-to-maturity or as trading are classified as available-for-sale, and are carried at fair market value, with the unrealized gains and losses included in the determination of comprehensive income and reported in stockholders’ equity. As of March 31,June 30, 2017 and December 31, 2016, all of the Company’s marketable securities were classified as available-for-sale. Marketable securities are recorded as either short-term or long-term on the balance sheet based on the contractual maturity date. The fair value of all securities is determined by quoted market prices, market interest rate inputs, or other than quoted prices that are observable either directly or indirectly (as of the end of the reporting period). Declines in fair value below the Company’s carrying value deemed to be other than temporary are charged against net earnings. As of March 31,June 30, 2017, the Company had no short or long term investments, since those funds were used to pay for a portion of the acquisition of Nanosphere.Nanosphere, Inc. (Nanosphere).

Available-for-sale securities consisted of the following as of March 31,June 30, 2017 (in thousands):

There were no available-for-sale debt securities as of March 31,June 30, 2017 orand December 31, 2016.

Expected maturities may differ from contractual maturities because the issuers of the securities may have the right to prepay obligations without prepayment penalties.

Non-Marketable Securities and Other-Than-Temporary Impairment

During the year ended December 31, 2016, and in the threesix months ended March 31,June 30, 2017, respectively, the Company made a $1.0 million and $0.5 million minority interest investment respectively,(an aggregate of $2.0 million), in a private company based in the U.S. that is focused on development of next generation technologies. This minority interest is included at cost in other long-term assets on the Company’s Consolidated Balance Sheets as the Company does not have significant influence over the investee since the Company owns less than 20% of the voting equity in the investee and the investee is not publicly traded. Although we may invest further in this entity over the course of the next several quarters, we do not anticipate our ownership interest to exceed 20% in the short term.

The Company owns a minority interest in a second private company based in the U.S. through its investment of $1.0 million in the third quarter of 2012.  This minority interest is included at cost in other long-term assets on the Company’s Consolidated Balance Sheets as the Company does not have significant influence over the investee since the Company owns less than 20% of the voting equity in the investee and the investee is not publicly traded.

The Company regularly evaluates the carrying value of its cost-method investment for impairment and whether any events or circumstances are identified that would significantly harm the fair value of the investment. The primary indicators the Company utilizes to identify these events and circumstances are the investee's ability to remain in business, such as the investee's liquidity and rate of cash use, and the investee’s ability to secure additional funding and the value of that additional funding. In the event a decline in fair value is judged to be other-than-temporary, the Company will record an other-than-temporary impairment charge in Other income, net in the Consolidated Statements of Comprehensive Income. As the inputs utilized for the Company's periodic impairment assessment are not based on observable market data, the determination of fair value of this cost-method investment is classified within Level 3 of the fair value hierarchy. See Note 54 - Fair Value Measurement to our Condensed Consolidated Financial Statements for further discussion. To determine the fair value of this investment, the Company uses all available financial information related to the entities, including information based on recent or pending third-party equity investments in these entities. In certain instances, a cost-method investment's fair value is not estimated as there are no identified events or changes in the circumstances that may have a significant adverse effect on the fair value of the investment and to do so would be impractical.



NOTE 43 — INVENTORIES, NET

Inventories are stated at the lower of cost or net realizable value, with cost determined according to the standard cost method, which approximates the first-in, first-out method. Net realizable value is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company routinely assesses its on-hand inventory for timely identification and measurement of obsolete, slow-moving or otherwise impaired inventory.

NOTE 54 — FAIR VALUE MEASUREMENT

The Fair Value Measurements and Disclosures Topic of the Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) defines fair value, establishes a framework for measuring fair value under U.S. GAAP and enhances disclosures about fair value measurements. Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The ASC describes a fair value hierarchy based on the following three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last unobservable:
 
Level 1 –Quoted prices in active markets for identical assets or liabilities.
 
Level 2 –Inputs other than Level 1 that are observable, either directly or indirectly, such as 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 market data for substantially the full term of the assets or liabilities.
 
Level 3 –Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The Company determines the fair value of its investment portfolio assets by obtaining non-binding market prices from its third-party portfolio managers on the last day of the quarter, whose sources may use quoted prices in active markets for identical assets (Level 1 inputs) or inputs other than quoted prices that are observable either directly or indirectly (Level 2 inputs) in determining fair value. There were no transfers between Level 1, Level 2, or Level 3 measurements for the three or six month period ended March 31,June 30, 2017.

The following table represents the Company’s fair value hierarchy for its financial assets and liabilities measured at fair value on a recurring basis as of March 31,June 30, 2017 and December 31, 2016 (in thousands):

Basic net income per share is computed by dividing the net income for the period by the weighted average number of common shares outstanding during the period. Diluted net income per share is computed by dividing the net income for the period by the weighted average number of common and common equivalent shares outstanding during the period. Stock options to acquire approximately 2.32.5 million and 0.60.4 million shares for the three months ended March 31,June 30, 2017 and 2016, and 2.0 million and 0.4 million shares for the six months ended June 30, 2017 and 2016, respectively, were excluded from the computations of diluted EPS because the effect of including those stock options would have been anti-dilutive.

We apply the two-class method of computing earnings per share, which requires the calculation of separate earnings per share amounts for our non-vested, time-based restricted stock awards with non-forfeitable dividends and for our common stock. Our non-vested, time-based restricted stock awards with non-forteitable rights tonon-forfeitable dividends are considered securities which participate in undistributed earnings with common stock. Under the two-class computation method, net losses are not allocated to participating securities unless the holder of the security has a contractual obligation to share in the losses. Our non-vested, time-based restricted stock awards with non-forteitablenon-forfeitable dividends do not have such an obligation so they are not allocated losses.

As of March 31,June 30, 2017, there was $17.2$15.3 million and $3.2$3.3 million of total unrecognized compensation costs related to Restricted Stock Awards (RSAs) and Restricted Stock Units (RSUs), respectively. This cost is expected to be recognized over a weighted average period of 2.852.60 years for the RSAs and 2.262.35 years for the RSUs. The Company issues a small number of cash settled RSUs pursuant to the Company's equity incentive plan in certain foreign countries. These grants do not result in the issuance of common stock and are considered immaterial by the Company.

The holders of these grants have the right to vote the related shares of common stock and receive all dividends declared and paid whether or not vested. The fair value of time-based restricted stock awards is calculated based on the market value of our common stock on the date of grant.

NOTE 1110 — INCOME TAXES
 
At the end of each interim reporting period, an estimate is made of the effective tax rate expected to be applicable for the full year. The estimated full year’s effective tax rate is used to determine the income tax rate for each applicable interim reporting period. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in the results of operations in the period of the enactment date. The effective tax rate for the threesix months ended March 31,June 30, 2017 was 34%31.2%, including amounts recorded for discrete events. This differs from the statutory rate of 35% primarily because of the worldwide mix of consolidated

earnings and losses before taxes and an assessment regarding the realizability of the Company’s deferred tax assets.taxes. The mix of profits for the 2017 fiscal year is estimated to have a higher concentration in the U.S. than in prior years, which isprofits are subject to a statutory U.S. federal and blended state rate of 37.5%. The Company’s tax expense reflects the full federal, various state, and foreign blended statutory rates. The Company is utilizing its net operating losses and tax credits in the U.S., Canada and the Netherlands and currently expects a full year effective tax rate of less than 35%. Therefore, cash taxes to be paid are expected to continue to be less than 15% of book tax expense.
 
The Company or one of its subsidiaries files income tax returns in the U.S. federal jurisdiction, Australia, Canada, China, Hong Kong, Japan, the Netherlands, and various states within the U.S.states. Due to net operating losses, the U.S., Canadian and Australian tax returns dating back to 2011 can still be reviewed by the taxing authorities. The Netherlands tax returns dating back to 2013 can still be reviewed by the taxing authorities. For the threesix months ended March 31,June 30, 2017, there were no material changes to the total amount of unrecognized tax benefits.  No material changes to this liability are expected within the next 12 months. The Company recognizes interest and penalties related to uncertain tax positions in the provision for income taxes.



NOTE 12 —11 - COMMITMENTS AND CONTINGENCIES

In the normal course of business, the Company is subject to claims, lawsuits and legal proceedings. When and if it appears probable in management's judgment, and based upon consultation with outside counsel, that we will incur monetary damages or other costs in connection with any claims or proceedings, and such costs can be reasonably estimated, we record the estimated liability in the financial statements.  If only a range of estimated losses can be estimated, we record an amount within the range that, in management's judgment, reflects the most likely outcome; if none of the estimates within that range is a better estimate than any other amount, we record the liability at the low end of the range of estimates. Any such accrual would be charged to expense in the appropriate period.   We disclose significant contingencies when the loss is not probable and/or the amount of the loss is not estimable, when we believe there is at least a reasonable possibility that a loss has been incurred.  We recognize costs associated with legal proceedings in the period in which the services were provided.


NOTE 1312 — RECENT ACCOUNTING PRONOUNCEMENTS

Recently adopted accounting guidance

In July 2015, the FASB issued guidance regarding the measurement of inventory. The new guidance requires inventory to be measured at the lower of cost and net realizable value, which is defined as the estimated selling price in the ordinary course of business, less reasonably predictable costs of completion, disposal and transportation. The Company adopted this standard during the quarter ended March 31, 2017, and its adoption did not have any impact on its consolidated financial statements.

Recent accounting guidance not yet adopted

In October 2016, the FASB issued guidance on income taxes which requires companies to recognize the income tax effects of intercompany sales and transfers of assets, other than inventory, in the income statement as income tax expense (or benefit) in the period in which the transfer occurs. The guidance is effective for annual periods beginning after December 15, 2017. Early adoption is permitted. The Company is currently evaluating the impact of the adoption of this guidance on its consolidated financial position and results of operations. The Company does not anticipate that this guidance will have a material impact on its consolidated financial statements.

In August 2016, the FASB issued specific guidance on eight cash flow classification issues that are not currently addressed by current U.S. GAAP and thereby reducereduced the current diversity in practice.  This guidance is effective for annual periods beginning after December 15, 2017. Early adoption is permitted. The Company does not anticipate that this guidance will have a material impact on its consolidated financial statements.

In February 2016, the FASB issued guidance requiring lessees to recognize a right-of-use asset and a lease liability on the balance sheet for all leases with the exception of short-term leases. The effective date of the new guidance is for the Company's first quarter of fiscal 2019 and early adoption is permitted. The new standard must be adopted using a modified retrospective transition and requires application of the new guidance at the beginning of the earliest comparative period presented. The Company is currently evaluating the impact of the adoption of this requirement on its consolidated financial statements, but does not anticipate that adoption of this guidance will have a material impact on its consolidated financial statements except for the addition of the right-of-use asset and a lease liability to the balance sheet.

In January 2016, the FASB issued guidance that changes how entities measure equity investments that do not result in consolidation and are not accounted for under the equity method. Entities will be required to measure these investments at fair value at the end of each reporting period and recognize changes in fair value in net income. This guidance also changes certain disclosure requirements and other aspects of current U.S. GAAP. This guidance is effective for annual periods beginning after December 15, 2017. Early adoption is permitted. The Company does not anticipate that adoption of this guidance will have a material impact on its consolidated financial statements as the only potential impact would be related to the Company's cost-method investments discussed in Note 32 - Investments.

In May 2014, the FASB issued a new standard on revenue recognition which outlines a single comprehensive model to use in accounting for revenue arising from contracts with customers and supersedes most current revenue recognition guidance, including industry-specific guidance. The core principle of the revenue model is that an entity should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. In doing so, companies will need to use their judgment and make estimates more extensively than under current U.S. GAAP. These judgments may include identifying performance obligations in the contract, estimating the amount of variable consideration to include in the transaction price and allocating the transaction price to each separate performance obligation. The standard is designed to create greater comparability for financial statement users across industries and jurisdictions and also requires enhanced disclosures. On July 9, 2015, the FASB voted in favor of delaying the effective date of the new standard by one year, with early adoption permitted as of the original effective date. The guidance is effective for fiscal years, and interim periods within those years, beginning after December 15, 2017. The Company currently anticipates adopting the new standard effective January 1, 2018. The new standard permits two methods of adoption: retrospectively to each prior reporting period presented (full retrospective method), or retrospectively with the cumulative effect of initially applying the guidance recognized at the date of initial application (the modified retrospective method). The Company currently anticipates adopting the standard using the modified retrospective method. The Company has begun assessing its various revenue streams to identify performance obligations under this guidance and the key aspects of the standard that will impact the Company's revenue recognition process. Based upon ourthe Company's preliminary assessments, these standards maywill impact our allocation of contract revenue between various products and services, the timing of when those revenues are recognized and the treatmentrecognition of certain coststhe Company's royalty revenue as the Company has historically waited until the partners have reported end user sales to obtainrecognize royalty revenue. With the implementation of the standard, the Company expects to record a contract.cumulative adjustment increasing retained earnings which is estimated to be approximately one quarter of royalty revenue. After implementation, the Company will begin recording estimated royalty revenue each quarter to coincide with the timing of the end user sale by the partner, with any necessary corrections to the estimates in the following quarter. Given the diversity of its commercial arrangements, the Company is continuing to assess the impact these standards may have on its consolidated results of operation, financial position, cash flows and financial statement disclosures.

OVERVIEW

We develop, manufacture and sell proprietary biological testing technologies and products with applications throughout the diagnostics, pharmaceutical and life sciences industries. These industries depend on a broad range of tests, called assays, to perform diagnostic testing and conduct life science research.

We have established a position in several segments of the life sciences industry by developing and delivering products that meet a variety of customer needs in specific market segments, including multiplexing, accuracy, precision, sensitivity, specificity, reduction of labor and ability to test for proteins and nucleic acids. These needs are addressed by our proprietary technology, which allows the end user in a laboratory to perform biological testing in a multiplexed format. Multiplexing allows for many different laboratory results to be generated from one sample with a single assay. This is important because our end user customers, which include laboratory professionals performing research and clinical laboratories performing tests on patients as ordered by physicians and other laboratories, have a fundamental need to perform high quality testing as efficiently as possible. Until the availability of multiplexing technology such as our xMAP® (Multi-Analyte-Profiling) technology, the laboratory professional had to perform one assay at a time in a sequential manner, and if additional testing was required on a sample, a second assay would be performed to generate the second result, and so on until all the necessary tests were performed.


We have a full range of instruments using our xMAP technology: our LUMINEX 100/200™ systems offer 100-plex testing; our FLEXMAP 3D® system is our high-throughput, 500-plex testing system; and our MAGPIX® system provides 50-plex testing at a lower cost using imaging rather than flow cytometry. By using our xMAP technology, the end users are able to be more efficient by generating multiple simultaneous results per sample. We believe that this technology may also offer advantages in other industries, such as in food safety/animal health and bio-defense/bio-threat markets. Using the products Luminex has available today, up to 500 simultaneous analyte results can be determined from a single sample.

We primarily serve the diagnostics, pharmaceutical and life sciences industries by marketing products, including our specific testing equipment and assays, to various types of testing laboratories. We have a large installed base of systems that has grown primarily from the following:

placements made by customers within our Licensed Technologies Group, previously referred to as our "Partner Business" whoBusiness," which customers either:
license our xMAP technology and develop products that incorporate our xMAP technology into products that they then sell to end users, or
purchase our proprietary xMAP laboratory instrumentation and our proprietary xMAP microspheres and sell xMAP-based assay products and/or xMAP-based testing services, which run on the xMAP instrumentation, and pay a royalty to us; and
our direct sales force, within our Molecular Diagnostics Group, focusing on the sale of molecular diagnostic assays that run on our systems.

As of March 31,June 30, 2017, Luminex had 7579 strategic partners, of which 5051 have released commercialized reagent-based products utilizing our technology. Our remaining partners are in various stages of development and commercialization of products that incorporate our technology.

Following the completion of our acquisition (the Acquisition) of Nanosphere Inc. (Nanosphere) on June 30, 2016, our offering in the molecular diagnostic market segment expanded to include Nanosphere's proprietary diagnostic tools that enable rapid and accurate detection of respiratory, gastrointestinal and bloodstream infections. Nanosphere is a leader in the high-growth bloodstream infection testing segment with its U.S. Food and Drug Administration (FDA) cleared Verigene® Gram-Positive Blood Culture (BC-GP) and Gram-Negative Blood Culture (BC-GN) test panels for the early detection of pathogens associated with bloodstream infections. In addition to detecting bacteria, these panels also detect yeast and identify antibiotic resistance markers. In contrast to traditional methodologies, which can take several days, these assays enable physicians to identify the pathogen, including any associated resistance markers, and prescribe the most appropriate antibiotic regimen, all within 2.5 hours after identification of a positive blood culture. The ability for clinicians to make earlier, better informed therapeutic decisions results in improved patient outcomes and lower healthcare costs. In addition, Nanosphere has FDA-cleared products for the detection of gastrointestinal and respiratory infections. These include a targeted product for the detection of  C. difficile, as well as highly multiplexed molecular enteric, blood and respiratory pathogen panels which test for a wide spectrum of microorganisms often associated with these types of infections. With the addition of the Verigene platform, Luminex offers customers automatedsample to answer molecular platforms for both syndromic and targeted molecular diagnostic testing.

In addition to our menu of infectious disease tests, we are currently developing thea next generation Verigene System,system, Verigene II, that we anticipate will deliver improved user experience. This next generation system is designed to provide a reduced time to result and an improved user interface, including a room temperature cartridge, all in a fully automated sample to result system with an optimized footprint.

A primary focus for our growth is the development and sale of molecular diagnostic assays utilizing our proprietary MultiCode®and Verigene technologies for use on our installed base of systems. We utilize a direct sales model for sales of these products, which is intended to take advantage of our increasing installed base of instruments. Our assays are primarily focused on multiplexed applications for the human molecular clinical diagnostics market. Our assay products are currently focused on three segments of the molecular diagnostic testing market: human genetics, personalized medicine and infectious disease.


In addition to the sales to this installed base, in the fourth quarter of 2015 we received FDA clearance for our ARIES® System. The ARIES® Systemsystem is aour sample to answer platform for our MultiCode®-RTx technology, including IVD assays. The ARIES® system is a clinical test system thatwhich automates and integrates extraction of nucleic acid from a clinical sample, performs real-time polymerase chain reaction, (PCR), and detects multiple signals generated by target specific probes. The ARIES® Systemsystem is used with specific assays to measure multiple analytes indicative of infectious disease. The ARIES® Systemsystem uses internal barcode scanning and other advanced features to minimize operator errors. Each independent module supports from one to six cassettes, allowing both STAT and Batch testing. The ARIES® Systemsystem can run both In Vitro Diagnostics (IVD) and MultiCode® Analyte Specific Reagents (ASRs) simultaneously with a common Universal Assay Protocol. The ARIES® Systemsystem was commercially launched in the fourth quarter of 2015. We also received FDA clearance for2015 and the ARIES® HSV (herpes simplex virus) 1&2 Assay in the fourth quarterfollowing systems and assays are on market as of 2015; Conformité EuropéenneJuly 31, 2017:

Acquisition of Nanosphere - June 30, 2016

As previously reported in the 2016 10-K, we completed our acquisition of Nanosphere, Inc., a publicly-held molecular diagnostic company based in Northbrook, Illinoisthe Acquisition on June 30, 2016. The acquisitionAcquisition was an all cash transaction that was undertaken to expand the Company's access to the high-growth molecular microbiology market and to Nanosphere's portfolio of molecular testing solutions. As a result of the dilutive nature of the acquisition of Nanosphere, we believe bothAcquisition, our profitability and operating cash flows will behave been lower than our pre-acquisition, historical results through the end of the thirdsecond quarter of 2017; however,2017, on a percentage basis. However, we expect to maintain profitability and positive operating cash flows. In addition, Nanosphere has a portfolio with meaningfully lower gross margins than the pre-existing Luminex business and we expect the gross margins on the acquired portfolio to continue to negatively impact our consolidated gross margins in the near term; however, we expect synergies realized from the acquisition,Acquisition, increased sales volumes and the commercialization of the next generation Verigene System, Verigene II, to increase these gross margins in the long term. We currently anticipate that the acquisitionThe Acquisition and its related integration will bewere accretive to the Company's consolidated revenue and profitability and cash flow byin the fourthsecond quarter of 2017.



Material Partner Activity

Based upon a recentan agreement entered into in the first quarter of 2017, the Company will continue to sell its CF products to the Company’s largest customer, LabCorp, at least through the end of 2017, when LabCorp is expected to transfer its CF testing to an alternative technology.  As a result,Notwithstanding continued sales, we expect revenue contraction of our overall genetic portfolio of approximately $5.0 million in 2017, with the majority of the contraction attributable to declines in our pharmacogenomics (PGx) portfolio.  Also, as previously stated in our 2016 10-K, LabCorp has elected to develop the next iteration of one of their women's health products with another party. The transition time is significant and, as a result, we have negotiated significant minimum women's health purchases from LabCorp through June 2018. LabCorp has committed to acquire no less than $63.1 million of our women's health products from January 1, 2017 through June 30, 2018. This is in comparison to 2016 purchases of approximately $39.3 million. The anticipated future loss of the LabCorp business could have a material adverse effect on our growth and future results of operations, if we are unable to effectively attract new customers and/or increase sales with existing customers.

Consumables Sales and Royalty Revenue Trends

We have experienced significant fluctuations in consumable revenue over the past three years. Overall, the fluctuations manifested themselves through periodic changes in volume from our largest purchasing customers. On a quarterly basis, our largest customers account for approximately 70% of our total consumable sales volume. We expect these fluctuations to continue as the ordering patterns and inventory levels of our largest bulk purchasing partners remain variable. Additionally, even though we experience variability in consumable revenue, the key indicator of the success of our partners’ commercialization efforts is the rising level of royalties and reported royalty bearing sales.

Future Operations

We expect our areas of focus over the next twelve months to be:

delivering on our revenue growth goals;

accelerating development and commercialization of the assays on our sample-to-answersample to answer diagnostics systems;

increasing the growth of our partner business through enrichment of our existing partner relationships and the addition of new partners;

developing
completing development and commercializing the next generation system for Verigene,®, Verigene II;

realizing the anticipated synergies of the acquisition of NanosphereAcquisition and associated integration, including the effective incorporation of our combined sales force in the marketplace;

improvement of ARIES®and Verigene gross margins;

placements of our ARIES® system, our sample-to-answersample to answer platform for our MultiCode-RTxMultiCode®-RTx technology, including IVD assays;

market acceptance of our Respiratory Viral Panel line of IVD assays;


commercialization, regulatory clearance and market adoption of products, including commercialization of MultiCode®analyte specific reagents outside of the United States;

maintenance and improvement of our existing products and the timely development, completion and successful commercial launch of our pipeline products;

adoption and use of our platforms and consumables by our customers for their testing services;

expansion and enhancement of our installed base of systems and our market position within our identified target market segments; and

monitoring and mitigating the effect of the ongoing uncertainty in global finance markets and changes in government funding on planned purchases by end users.

We anticipate continued revenue concentration in our higher margin items (assays, consumables and royalties) contributing to favorable, but variable, gross margin percentages. Additionally, we believe that a sustained investment in research and development is necessary in order to meet the needs of our marketplace and provide a sustainable new product pipeline. We may experience volatility in research and development expenses as a percentage of revenue on a quarterly basis as a result of the timing of development expenses, clinical validation and clinical trials in advance of the commercial launch of our new products.

CRITICAL ACCOUNTING POLICIES AND ESTIMATES

The discussion and analysis of our financial condition and results of operations are based upon our condensed consolidated financial statements, which have been prepared in accordance with U.S. GAAP for interim financial statements. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Estimates and assumptions are reviewed periodically. Actual results may differ from these estimates under different assumptions or conditions.

Management believes there have been no significant changes during the quarter ended March 31,June 30, 2017 to the items that we disclosed as our critical accounting policies and estimates in Management’s Discussion and Analysis of Financial Condition and Results of Operations in the 2016 10-K.

We continue to experience revenue concentration in a limited number of customers. Five customers accounted for 48%50% (two of whom were 18%21% and 17%15%, respectively, and no other customer exceeded 6%) of consolidated total revenue in the firstsecond quarter of 2017. For comparative purposes, these top five customers accounted for 56%49% (two of whom were 23%19% and 15%14%, respectively, and no other customer exceeded 8%) of total consolidated revenue in the firstsecond quarter of 2016.

Revenue from the sale of systems and peripheral components increased 2%10% to $8.5$9.9 million for the three months ended March 31,June 30, 2017 from $8.3$9.0 million for the three months ended March 31,June 30, 2016, resulting primarily from the acquisitioninclusion of Nanosphere,Verigene system sales, as well as a more favorable mix in sales of multiplexing analyzers with lowerfewer sales of LUMINEX 100/200 systems, partially offset by more sales of FLEXMAP 3D systems whose average sales price is higher than the LUMINEX 100/200 systems. Excluding the impact of the Acquisition, revenue from the sale of systems and peripheral components increased by 2% for the three months ended June 30, 2017 from the comparable period in 2016. We sold 242270 multiplexing analyzers in the firstsecond quarter of 2017, as compared to 255277 multiplexing analyzers sold for the corresponding prior year period. For the three months ended March 31,June 30, 2017, five of our partners accounted for 187214 multiplexing analyzers, or 77%79%, of total multiplexing analyzers sold, as compared to five of our partners accounting for 198200 multiplexing analyzers, or 78%72%, of total multiplexing analyzers sold for the three months ended March 31,June 30, 2016.

Consumable sales, comprised of microspheres and sheath fluid, increased 30% to $15.4remained constant at $13.3 million for the three months ended March 31,June 30, 2017 from $11.9 million forand the three months ended March 31,June 30, 2016. During the three months ended March 31,June 30, 2017, we had 1817 bulk purchases of consumables totaling approximately $12.4$10.3 million (78% of total consumable revenue), ranging from $0.1 million to $4.0 million, as compared with 24 bulk purchases totaling approximately $10.7 million (80% of total consumable revenue), ranging from $0.1 million to $6.4 million, as compared with the same number of bulk purchases totaling approximately $9.1 million (77% of total consumable revenue), ranging from $0.1 million to $3.4$2.2 million, for the three months ended March 31,June 30, 2016. The increase in revenue from bulk purchases in the first quarter of 2017 is the primary driver to the increase in consumable revenue from the prior year quarter. We expect fluctuations in consumable sales on an ongoing basis. Partners who reported royalty bearing sales accounted for $12.3$8.4 million, or 80%63%, of consumable sales for the three months ended March 31,June 30, 2017 compared to $8.6$7.3 million, or 73%55%, of the total consumable sales for the three months ended March 31, 2016.June 30, 2016.

Royalty revenue, which results when our partners sell products or testing services incorporating our technology, increased modestlydecreased by 1%5% to $11.6$10.8 million for the three months ended March 31,June 30, 2017 from $11.5$11.4 million for the three months ended March 31,June 30, 2016.  This increasedecrease is the result of an increase in base royalties of $0.5 million partially offset by a decrease in minimum royalty payments and royalty audit findings and other adjustments of approximately $0.4$0.5 million. We expect modest fluctuations in the royalties submitted quarter to quarter based upon the varying contractual terms, differing reporting and payment requirements, and the addition of new partners. Our partners’ end user sales may reflect volatility from quarter to quarter and therefore, that same volatility is reflected in our reported royalty revenues on a quarterly basis.

Assay revenue increased 38%46% to $37.4$37.8 million for the three months ended March 31,June 30, 2017 from $27.0$25.9 million for the three months ended March 31,June 30, 2016, driven primarily by the revenue stream from the acquisitioninclusion of Nanosphere,Verigene revenue, which accounted for more than 90%74% of the 46% increase, in addition to increased sales of ARIES and infectious disease testing assays. Excluding the impact of the Acquisition, assay revenue increased by 12% for the three months ended June 30, 2017 from the comparable period in 2016. Additionally, infectious disease testing assay products and genetic testing assay products represented 81% and 19%, respectively, of total assay revenue in the second quarter of 2017, compared to 66% and 34%, respectively, in the second quarter of 2016. Revenue for our primary assay portfolios increased in infectious disease testing products by 5% while79%, driven predominantly by the addition of Verigene assays, for the three months ended June 30, 2017 from the second quarter of 2016. This was partially offset by a decline in our genetic testing assay products decreased by 8%of 18% for the three months ended March 31,June 30, 2017 from the first quarter ofcomparable period in 2016. This decrease in genetic testing assay products was attributable to pricing and reimbursement challenges within the pharmacogenetic market segment and the departure of a key customer, causing us to shift our focus towards infectious disease testing. Additionally, infectious disease testing assay products and genetic testing assay products represented 55% and 18%, respectively, of total assay revenue in the first quarter of 2017, compared to 72% and 28%, respectively, in the first quarter of 2016. The Verigene assay revenue stream from Nanosphere represents approximately 25%23% of total assay revenue for the three months ended March 31,June 30, 2017, and consisted primarily of infectious disease testing assay products.our sample to answer clinical tests. Our largest customer, by revenue, accounted for 35%41% of total assay revenue for the three months ended March 31,June 30, 2017 compared to 51%45% for the three months ended March 31,June 30, 2016. No other customer accounted for more than 10% of total assay revenue during those periods. As disclosed previously, cystic fibrosis revenue from our largest assay customer is expected to transition to a competing technology and, although timing is uncertain, the loss of a significant portion of that revenue is now expected in early 2018. As discussed under "Material Partner Activity", and previously disclosed in our prior quarterly report, the same assay customer has recently informed us it plansthat they plan on developing the next iteration of itstheir women's health portfolio with another party, which could negatively impact our assay revenue in 2018 and beyond.

Service revenue, comprised of extended warranty contracts earned ratably over the term of a contract and time and materials for billable service work not under an extended warranty contract, increased $0.5$0.2 million, or 20%10%, to $2.9$2.8 million for the firstsecond quarter of 2017 compared to $2.5 million in the firstsecond quarter of 2016. This increase is primarily attributable to the acquisitioninclusion of Nanosphere,Verigene service revenue, which accounted for more than 60%10% of total service revenue for the second quarter of 2017.  Excluding the impact of the 20% increase, as well as due to an increaseAcquisition, service revenue decreased by 2% for the three months ended June 30, 2017 from the comparable period in the number of installed base of systems.2016. As of March 31,June 30, 2017, we had 1,6691,930 Luminex systems covered under extended service agreements, and $4.7of which approximately 150 are attributable to Verigene systems added since our Acquisition on June 2016. In addition, we have $4.9 million in deferred revenue related to those contracts. As of March 31,June 30, 2016, we had 1,7901,835 Luminex systems covered under extended service agreements and $4.8$4.9 million in deferred revenue related to those contracts.


Other revenue, which includes training revenue, shipping revenue, miscellaneous part sales, amortized license fees and revenue from agreements with U.S. government agencies, increased 7% to $2.0 million for the three months ended March 31, 2017 compareddecreased 8% to $1.9 million for the three months ended March 31, 2016.June 30, 2017 compared to $2.1 million for the three months ended June 30, 2016, primarily driven by a reduction in government contract revenue. We expect this trend to continue in the near term as our focus has shifted away from these government contract opportunities.

Gross Profit. Gross profit increased to $52.8$50.1 million for the three months ended March 31,June 30, 2017, as compared to $44.8$44.9 million for the three months ended March 31,June 30, 2016. However, gross margin (gross profit as a percentage of total revenue) was 68%65% for the three months ended March 31,June 30, 2017, a decrease from the prior year quarter of 71%70%. The decrease in gross margin is primarily attributable to the acquisitioninclusion of Nanosphere. For comparison, followingVerigene product revenue, which accounted for approximately 80% of the acquisition of Nanosphere on June 30, 2016 our gross margin percentages were 64% and 61% for the third and fourth quarters of 2016, respectively.decline. The acquired NanosphereVerigene portfolio has meaningfully lower gross margins than the pre-existing Luminex business. For comparison, following the Acquisition on June 30, 2016 our gross margin percentages were 64%, 61% and 68% for the third and fourth quarters of 2016 and the first quarter of 2017, respectively. We expect the gross margins on the acquired portfolio to continue to negatively impact our consolidated gross margins in the near term; however, we expect synergies realized from the acquisition,Acquisition, increased sales volumes and the commercialization of the next generation Verigene system, Verigene II, to increase these gross margins in the longer term. We currently believe that the gross margin percentages experienced in the third and fourth quarter of 2016 represent the most significant negative impact that we expect to experience from the Nanosphere portfolio margin. However, we anticipate continued fluctuation in gross margin and related gross profit primarily as a result of variability in consumable and system purchases and seasonality effects inherent in our assay revenue.

Research and Development Expense. Research and development expense increased to $12.4$12.3 million, or 16% of total revenue, for the three months ended March 31,June 30, 2017 from $11.0$11.5 million, or 17%18% of total revenue, for the three months ended March 31,June 30, 2016. The increase in research and development expense was primarily a result of the addition of Nanosphere's expenses, as well as higher costs for clinical trials of ARIES assays, partially offset by savings from the previously announced reorganization in December 2016.  Research and development headcount as of March 31,June 30, 2017 was 194, including former Nanosphere employees, as195 compared to 197208 as of March 31,June 30, 2016. The focus of our research and development activities is the development and commercialization of a pipeline of assays for the ARIES® system and the development of the next generation Verigene system, Verigene II, and assays.

Selling, General and Administrative Expense. Selling, general and administrative expenses, excluding the amortization of acquired intangible assets, increased to $24.0was $28.2 million for the three months ended March 31,June 30, 2017, an increase of $4.0 million from $20.4the three months ended June 30, 2016 and an increase of $4.2 million forfrom the three months ended March 31, 2016.2017. Over 75% of the increase from the prior year period was attributable to the addition of Nanosphere's expenses duringfor the three months ended June 30, 2017. On a sequential basis, expenses were higher primarily resulting from stock compensation reversals in the prior quarter for employees who left the Company, as well as one-time employee separation costs of $0.5 million included in the current quarter. Selling, general and administrative headcount as of March 31,June 30, 2017 was 370, including Nanosphere employees,365 as compared to 317323 as of March 31,June 30, 2016. As a percentage of revenue, selling, general and administrative expense, excluding the amortization of acquired intangible assets, was 31%37% in the firstsecond quarter of 2017, down from 32%38% in the firstsecond quarter of 2016.

Amortization of Acquired Intangible Assets. Amortization of acquired intangible assets increased to $2.4$2.2 million for the three months ended March 31,June 30, 2017 from $1.6$1.7 million for the three months ended March 31,June 30, 2016. The increase was primarily driven by the acquired intangible assets from the acquisition of NanosphereAcquisition, which began amortizing in July 2016.

Income taxes. Our effective tax rate for the three months ended March 31,June 30, 2017 was 34%26%, reflecting a $4.8$1.9 million expense, as compared to 26%7%, or a $3.1$0.4 million expense, for the three months ended March 31,June 30, 2016. We expect our consolidated effective tax rate to be in the 25% to 35% range over the next several years, absent any other significant discrete items. We continue to assess our business model and its impact in various tax jurisdictions. Currently we are experiencing a high concentration of revenue in the U.S. relative to the rest of the world, which could be impacted by future revenue mix and worldwide tax rate adjustments.

Total revenue increased by 21% to $154.2 million for the six months ended June 30, 2017 from $127.1 million for the comparable period in 2016. The increase was primarily attributable to increases in assay, system, and consumable sales, driven in part by the Acquisition, which contributed approximately 76% of the 21% growth in total revenue. Excluding the impact of the Acquisition, revenue increased by 5% for the six months ended June 30, 2017 from the comparable period in 2016.

We continue to experience revenue concentration in a limited number of customers. Five customers accounted for 49% (two of whom were 19% and 17%, respectively, and no other customer exceeded 6%) of consolidated total revenue in the six months ended June 30, 2017. For comparative purposes, these top five customers accounted for 52% (two of whom were 21% and 14%, respectively, and no other customer exceeded 7%) of total revenue in the six months ended June 30, 2016.

Revenue from the sale of systems and peripheral components increased 6% to $18.4 million for the six months ended June 30, 2017 from $17.3 million for the six months ended June 30, 2016, resulting primarily from the inclusion of Verigene system sales, as well as a more favorable mix in sales of multiplexing analyzers with fewer sales of LUMINEX 100/200 systems, partially offset by more sales of FLEXMAP 3D systems whose average sales price is higher than the LUMINEX 100/200 systems. Excluding the impact of the Acquisition, revenue from the sale of systems and peripheral components remained consistent for the six months ended June 30, 2017 from the comparable period in 2016. We sold 512 multiplexing analyzers in the six months ended June 30, 2017, as compared to 532 multiplexing analyzers sold for the corresponding prior year period. For the six months ended June 30, 2017, five of our partners accounted for 388, or 76%, of total multiplexing analyzers sold.  Five of our partners accounted for 391, or 74%, of total multiplexing analyzers sold for the six months ended June 30, 2016.

Consumable sales increased 14% to $28.7 million for the six months ended June 30, 2017 compared to $25.2 million for the six months ended June 30, 2016. We had 35 bulk purchases of consumables totaling approximately $22.7 million (79% of total consumable revenue), ranging from $0.1 million to $6.4 million, during the six months ended June 30, 2017, as compared with 42 bulk purchases totaling approximately $19.8 million (79% of total consumable revenue), ranging from $0.1 million to $3.4 million, for the six months ended June 30, 2016.  The increase in revenue from bulk purchases in the six months ended June 30, 2017 is the main driver to the increase in consumable revenue from the prior year period. We expect fluctuations in consumable sales on an ongoing basis. Partners who reported royalty bearing sales accounted for $20.7 million, or 72%, of consumable sales for the six months ended June 30, 2017 compared to $16.0 million, or 63%, of the total consumable sales for the six months ended June 30, 2016.

Royalty revenue decreased 2% to $22.4 million for the six months ended June 30, 2017 from $22.8 million for the six months ended June 30, 2016.  This decrease is primarily attributable to a decrease in minimum royalty payments and royalty audit findings and other adjustments, which was partially offset by an increase in base royalties of approximately $0.4 million as a result of the timing of when our partners report end user sales. We expect modest fluctuations in the royalties submitted quarter to quarter based upon the varying contractual terms, differing reporting and payment requirements, and the addition of new partners. Our partners’ end user sales may reflect volatility from quarter to quarter and therefore, that same volatility is reflected in our reported royalty revenues on a quarterly basis.


Assay revenue increased 42% to $75.2 million for the six months ended June 30, 2017 from $52.9 million for the six months ended June 30, 2016, driven primarily by the inclusion of Verigene revenue, which contributed 82% of the 42% increase, in addition to increased sales of ARIES and infectious disease testing assays. The remaining 7% of growth is attributable to increased sales in infectious disease testing assays. Additionally, infectious disease testing and genetic testing assay products represented 81% and 19%, respectively, of total assay revenue in the six months ended June 30, 2017, compared to 69% and 31%, respectively, in the six months ended June 30, 2016. Our infectious disease testing assay portfolio increased 67% from the first six months of 2016, primarily driven by the addition of Verigene assays, while our genetic testing assay portfolio decreased 14% over the comparable time period.  This decrease in genetic testing assay products was primarily attributable to pricing and reimbursement challenges within the pharmacogenetic market segment and the departure of a key customer, causing us to shift our focus towards infectious disease testing. The Verigene assay revenue stream represents approximately 24% of total assay revenue for the six months ended June 30, 2017, and consisted primarily of our sample to answer clinical tests. Our largest customer, by revenue, accounted for 38% of total assay revenue for the six months ended June 30, 2017 compared to 48% for the six months ended June 30, 2016. No other customer accounted for more than 10% of total assay revenue during those periods. As disclosed previously, cystic fibrosis revenue from our largest assay customer is expected to transition to a competing technology and, although timing is uncertain, the loss of a significant portion of that revenue is now expected in early 2018. As discussed under "Material Partner Activity" and previously disclosed in our prior quarterly report, the same assay customer informed us that they plan on developing the next iteration of their women's health portfolio with another party, which could negatively impact our assay revenue in 2018 and beyond.

Service revenue, comprised of extended warranty contracts earned ratably over the term of a contract and time and materials for billable service work not under an extended warranty contract, increased 15% to $5.7 million for the six months ended June 30, 2017 compared to $5.0 million for the six months ended June 30, 2016. This increase is primarily attributable to the inclusion of Verigene service revenue, which accounted for more than 80% of the 15% increase. Excluding the impact of the Acquisition, service revenue increased by 2% for the six months ended June 30, 2017 from the comparable period in 2016.

Other revenue, which includes training revenue, shipping revenue, miscellaneous part sales, amortized license fees, and revenue from agreements with U.S. government agencies, decreased modestly to $3.9 million for the six months ended June 30, 2017 compared to $4.0 million for the six months ended June 30, 2016.

Gross Profit. Gross profit increased to $102.8 million for the six months ended June 30, 2017, as compared to $89.7 million for the six months ended June 30, 2016. Gross margin (gross profit as a percentage of total revenue) was 67% for the six months ended June 30, 2017, a decrease of four percentage points from the six months ended June 30, 2016. This decrease in gross margin was attributable to the inclusion of Verigene product revenue, where the acquired portfolio currently has meaningfully lower gross margins than the pre-existing Luminex business. We expect the gross margins on the acquired portfolio to continue to negatively impact our consolidated gross margins in the near term; however, we expect synergies realized from the Acquisition, increased sales volumes and the commercialization of the next generation Verigene system, Verigene II, to increase these gross margins in the longer term. We anticipate continued fluctuation in gross margin and related gross profit primarily as a result of variability in consumable and system purchases and seasonality effects inherent in our assay revenue.

Research and Development Expense. Research and development expense increased to $24.7 million, or 16% of total revenue, for the six months ended June 30, 2017 from $22.6 million, or 18% of total revenue, for the six months ended June 30, 2016. The increase in research and development expense was primarily the result of the addition of Nanosphere's expenses and higher expenses driven by clinical trials of ARIES assays, partially offset by savings from the previously announced reorganization in December 2016.  Research and development headcount as of June 30, 2017 was 195 as compared to 208 as of June 30, 2016. The focus of our research and development activities is the development and commercialization of a pipeline of assays for the ARIES® system and the development of the next generation Verigene system, Verigene II, and assays.

Selling, General and Administrative Expense. Selling, general and administrative expenses, excluding the amortization of acquired intangible assets, increased to $52.2 million for the six months ended June 30, 2017 from $44.5 million for the six months ended June 30, 2016, primarily resulting from the Acquisition in addition to higher sales and marketing expenses driven by increased headcount and marketing activities. This increase was partially offset by the Nanosphere acquisition costs of $2.0 million that were recorded in the six months ended June 30, 2016. Selling, general and administrative headcount as of June 30, 2017 was 365 as compared to 323 as of June 30, 2016. As a percentage of revenue, selling, general and administrative expense, excluding the amortization of acquired intangible assets, was 34% in the first six months of 2017, compared to 35% in the first six months of 2016.

Amortization of Acquired Intangible Assets. Amortization of acquired intangible assets increased to $4.5 million for the six months ended June 30, 2017 from $3.3 million for the six months ended June 30, 2016. The increase was primarily driven by the acquired intangible assets from the Acquisition which began amortizing in July 2016.

Income taxes. Our effective tax rate for the six months ended June 30, 2017 was 31%, reflecting a $6.7 million expense, as compared to 19%, or a $3.5 million expense, for the six months ended June 30, 2016. The increase in rate is attributable to the high concentration of revenue in the U.S. that we are experiencing relative to the rest of the world, which could be impacted by future revenue mix and worldwide tax rate adjustments. We expect our consolidated effective tax rate to be in the 25% to 35% range over the next several years, absent any other significant discrete items. We continue to assess our business model and its impact in various tax jurisdictions.

As of March 31,June 30, 2017, we held cash and cash equivalents of $86.5$103.7 million and had working capital of $143.5$158.4 million. At December 31, 2016, we held cash and cash equivalents of $93.5 million and had working capital of $133.5 million. The $7.0$10.3 million decreaseincrease in cash, cash equivalents and investments is primarily attributable to a decreasean increase in operating cash flows of the Company in the amount of $1.5$20.6 million for the threesix months ended March 31,June 30, 2017 driven primarily by: (i) an increase in accounts receivable, (ii) a decrease in accrued liabilities resulting from the timingby net income of payment of previously accrued bonuses and commissions, (iii)$14.8 million. These operating cash flows were partially offset by capital expenditures of $3.4$6.4 million during the first three monthsand dividends paid of 2017, and (iv) the payment of minimum tax withholdings on net share settlements of equity awards.$2.6 million.

As a result of the dilutive nature of the acquisition of Nanosphere, we believe bothAcquisition, our profitability and operating cash flows will behave been lower than our recent historical results through the end of the thirdsecond quarter of 2017; however, we expect to maintain profitability2017, on a percentage basis. The Acquisition and positive operating cash flows. We currently anticipate that the acquisition of Nanosphere and its related integration will bewas accretive to the Company's consolidated revenue and profitability and cash flow byin the fourthsecond quarter of 2017.

We have funded our operations to date primarily through the issuance of equity securities (in conjunction with an initial public offering in 2000, subsequent option exercises, and our secondary public offering in 2008) and cash generated from operations. Our cash reserves are typically held directly or indirectly in a variety of short-term, interest-bearing instruments, including non-government sponsored debt securities. We do not have any investments in asset-backed commercial paper, auction rate securities, or mortgage backed or sub-prime style investments.

Our future capital requirements will depend on a number of factors, including our success in developing and expanding markets for our products, payments under possible future strategic arrangements, continued progress of our research and development of potential products, the timing and outcome of regulatory approvals, the need to acquire licenses to new technology, costs associated with strategic acquisitions including integration costs and assumed liabilities, the status of competitive products and potential costs associated with both protecting and defending our intellectual property. Additionally, actions taken as a result of ongoing internal evaluations of our business could result in expenditures not currently contemplated in our estimates for 2017.

One of our short term projects that is expected to require significant capital to complete is our current in-process research and development of the next generation Verigene System,system, Verigene II. We currently expect to initiate clinical studies on the system and its first assay in 2017 and anticipate initial commercialization in 2018. The estimated aggregate cost to complete this project, including completion of development of the Verigene II system, cartridge, software and the initial assay, validation, verification, clinical trials and regulatory submission, is between $18.0$14.0 million and $20.0$18.0 million and is included in our research and development budget for 2017 and 2018. We believe that our existing cash and cash equivalents are sufficient to fund our operating expenses, capital equipment requirements and other expected liquidity requirements for the coming twelve months. Factors that could affect our capital requirements, in addition to those listed above, include, without limitation: (i) continued collections of accounts receivable consistent with our historical experience; (ii) our ability to manage our inventory levels consistent with past practices; (iii) volatility in our key partners' consumable purchasing patterns; (iv) execution of partnership agreements that include significant up front license fees; (v) execution of our stock repurchase and dividend programs from time to time and (vi) executing strategic investment or acquisition agreements requiring significant cash consideration. See also the "Safe Harbor Cautionary Statement" of this report and the risk factors in the 2016 10-K and our other filings with the SEC.

As announced in February 2017, the Board of Directors initiated a cash dividend program under which the Company anticipates it will pay a regular quarterly cash dividend. The timing and amount of future dividends and stock repurchases will vary based on a number of factors, including future capital requirements for strategic transactions, the availability of financing on acceptable terms, debt service requirements, changes to applicable tax laws or corporate laws, changes to our business model and periodic

determination by our Board of Directors whether cash dividends are in the best interests of stockholders as a proper capital allocation and whether they are in compliance with applicable laws and agreements of the Company.

Based upon a recently entered agreement, the company will continue to sell its CF products to the Company’s largest customer, LabCorp, until at least the end of 2017 when LabCorp is expected to transfer its CF testing to an alternative technology.  Overall, we currently expect contraction of our genetic portfolio of approximately $5$5.0 million in 2017, with the majority of the contraction attributable to declines in our PGx portfolio.  Also, as previously disclosed, LabCorp informed us, following a request for proposal process, that they elected to develop the next iteration of one of their women's health products with another party. The transition time is significant and, as a result, we have negotiated a significant minimum women's health purchases through June 2018.  LabCorp has committed to acquire no less than $63.1 million of our women's health products from January 1, 2017 through June 30, 2018. This is in comparison to 2016 purchases of $39.3 million. Based upon an agreement entered into in the first quarter of 2017, the company will continue to sell its CF products to the Company’s largest customer, LabCorp, until at least the end of 2017 when LabCorp is expected to transfer its CF testing to an alternative technology.

To the extent our capital resources are insufficient to meet future capital requirements, we will have to raise additional funds to continue the development and deployment of our technologies, or to supplement our position through strategic acquisitions. There can be no assurance that debt or equity funds will be available on favorable terms, if at all. Any downgrade in our credit rating could adversely affect our ability to raise debt capital on favorable terms, or at all. To the extent that additional capital is raised through the sale of equity or convertible debt securities, the issuance of those securities could result in dilution to our stockholders. Moreover, incurring debt financing could result in a substantial portion of our operating cash flow being dedicated to the payment of principal and interest on such indebtedness, could render us more vulnerable to competitive pressures and economic downturns and could impose restrictions on our operations. If adequate funds are not available, we may be required to curtail operations significantly or to obtain funds through entering into agreements on unattractive terms.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Interest Rate Risk. Our interest income is sensitive to changes in the general level of domestic interest rates, particularly since our investments are in short-term instruments available-for-sale. A 50 basis point fluctuation from average investment returns as of March 31,June 30, 2017 would yield a less than 0.5% variance in overall investment return, which would not have a material effect on our financial condition.

Foreign Currency Risk. Our international business is subject to risks, including, but not limited to: foreign exchange rate volatility, differing tax structures, unique economic conditions, other regulations and restrictions, and changes in political climate. Accordingly, our future results could be materially adversely impacted by changes in these and other factors.

As of March 31,June 30, 2017, as a result of our foreign operations, we have costs, assets and liabilities that are denominated in foreign currencies, primarily Canadian dollars and to a lesser extent the Euro, Renminbi, Hong Kong dollar and Yen. For example, some fixed asset purchases and certain expenses in our Canadian subsidiary are denominated in Canadian dollars while sales of products are primarily denominated in U.S. dollars. Transactions in our Netherlands, Japanese and Hong Kong subsidiaries are primarily denominated in Euros, Yen and Hong Kong dollars, respectively. WithThe majority of transactions, with the exception of our initial capital investment, the majority of transactions in our Chinese subsidiary are denominated in Renminbi. As a consequence, movements in exchange rates could cause our foreign currency denominated expenses to fluctuate as a percentage of net revenue, affecting our profitability and cash flows. A significant majority of our revenues are denominated in U.S. dollars. The impact of foreign exchange rates on foreign denominated balances will vary in relation to changes between the U.S. dollar, Canadian dollar, Euro, Yen, Renminbi and Hong Kong dollar exchange rates. A 10% change in these exchange rates in relation to the U.S. dollar would result in an income statement impact of approximately $1.1$1.0 million on foreign currency denominated asset and liability balances as of March 31,June 30, 2017. As a result of our efforts to expand globally, in the future we will be exposed to additional foreign currency risk in multiple currencies; however, at this time, our exposure to foreign currency fluctuations is not material. We regularly assess the market to determine if additional strategies are appropriate to mitigate future risks.

In addition, the indirect effect of fluctuations in interest rates and foreign currency exchange rates could have a material adverse effect on our business, financial condition and results of operations. For example, currency exchange rate fluctuations could affect international demand for our products. In addition, interest rate fluctuations could affect our customers’ buying patterns. Furthermore, interest rate and currency exchange rate fluctuations may broadly influence the United States and foreign economies resulting in a material adverse effect on our business, financial condition and results of operations. As a result, we cannot give any assurance as to the effect that future changes in foreign currency rates will have on our consolidated financial position, results of operations or cash flows. Our aggregate foreign currency transaction lossgain of approximately $26,000$6,000 was included in determining our consolidated results for the quarter ended March 31,June 30, 2017.


ITEM 4. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures, as defined in Rule 13a-15(e) promulgated under the Securities Exchange Act of 1934, as amended (Exchange Act), which are designed to ensure that information required to be disclosed by us in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission’s rules and forms and that such information is accumulated and communicated to the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. We carried out an evaluation, under the supervision and with the participation of the Company’s management, including the Company’s Chief Executive Officer and Chief Financial Officer, of the effectiveness of the design and operation of the Company’s disclosure controls and procedures as of the end of the period covered by this quarterly report. Based on the evaluation and criteria of these disclosure controls and procedures, theour Chief Executive Officer and Chief Financial Officer concluded that the Company’s disclosure controls and procedures were effective at a reasonable assurance level and designed to ensure that material information relating to the Company and its subsidiaries would be made known to such officers on a timely basis.
 
Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Exchange Act Rule 13a-15(d) during the quarter ended March 31,June 30, 2017 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.


PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

In the normal course of business, the Company is subject to claims, lawsuits and legal proceedings. When and if it appears probable in management's judgment, and based upon consultation with outside counsel, that we will incur monetary damages or other costs in connection with any claims or proceedings, and such costs can be reasonably estimated, we record the estimated liability in the financial statements.  If only a range of estimated losses can be estimated, we record an amount within the range that, in management's judgment, reflects the most likely outcome; if none of the estimates within that range is a better estimate than any other amount, we record the liability at the low end of the range of estimates. Any such accrual would be charged to expense in the appropriate period.   We disclose significant contingencies when the loss is not probable and/or the amount of the loss is not estimable, when we believe there is at least a reasonable possibility that a loss has been incurred.  We recognize costs associated with legal proceedings in the period in which the services were provided.
