BIOLASE, Inc. (“Biolase” and, together with its consolidated subsidiaries, the “Company,” “we,” “our,” or “us”) incorporated in Delaware in 1987, is a medical device company that develops, manufactures, markets, and sells laser systems in dentistry and medicine and also markets, sells, and distributes dental imaging equipment, including digital x-rays, CAD/CAM intra-oral scanners and other imaging equipment.

The unaudited consolidated financial statements include the accounts of Biolase, Inc. and its wholly-owned subsidiaries and have been prepared on a basis consistent with the December 31, 2014 audited consolidated financial statements and include all material adjustments, consisting of normal recurring adjustments and the elimination of all material intercompany transactions and balances, necessary to fairly present the information set forth therein. These unaudited, interim, consolidated financial statements do not include all the footnotes, presentations, and disclosures normally required by accounting principles generally accepted in the United States of America (“GAAP”) for complete consolidated financial statements. Certain amounts have been reclassified to conform to current period presentations.

The consolidated results of operations for the three and nine months ended September 30, 2015 are not necessarily indicative of the results for the full year. The accompanying consolidated financial statements should be read in conjunction with the consolidated financial statements and notes thereto for the year ended December 31, 2014, included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2014 filed with the Securities and Exchange Commission (the “SEC”) on March 6, 2015, as amended on April 29, 2015 (the “2014 Form 10-K”).

The Company incurred a loss from operations and a net loss and used cash in operating activities for the three and nine months ended September 30, 2015. The Company has also suffered recurring losses from operations during the three years ended December 31, 2014.

As of September 30, 2015, the Company had working capital of approximately $22.0 million. The Company’s principal sources of liquidity at September 30, 2015 consisted of approximately $15.4 million in cash and restricted cash equivalent and $9.2 million of net accounts receivable.

Additional capital requirements may depend on many factors, including, among other things, the rate at which the Company’s business grows, demands for working capital, manufacturing capacity, and any acquisitions that the Company may pursue. From time to time, the Company could be required, or may otherwise attempt, to raise capital, through either equity or debt offerings, or enter into a line of credit facility. The Company cannot provide assurances that it will be able to successfully enter into any such equity or debt financings or line of credit facility in the future or that the required capital would be available on acceptable terms, if at all, or that any such financing activity would not be dilutive to its stockholders.

The preparation of these consolidated financial statements in conformity with GAAP requires the Company to make estimates and assumptions that affect amounts reported in the consolidated financial statements and the accompanying notes. Significant estimates in these consolidated financial statements include allowances on accounts receivable, inventory, and deferred taxes, as well as estimates for accrued warranty expenses, indefinite-lived intangible assets, and the ability of goodwill to be realized, revenue deferrals for multiple element arrangements, effects of stock-based compensation and warrants, contingent liabilities, and the provision or benefit for income taxes. Due to the inherent uncertainty involved in making estimates, actual results reported in future periods may differ materially from those estimates.

Information with respect to the Company’s critical accounting policies which management believes could have the most significant effect on the Company’s reported results and require subjective or complex judgments by management is contained in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the 2014 Form 10-K. Management believes that there have been no significant changes during the three and nine months ended September 30, 2015 in the Company’s critical accounting policies from those disclosed in Item 7 of the 2014 Form 10-K, except with regard to restricted cash equivalent as set forth below.

The restricted cash equivalent represents a revolving 90-day certificate of deposit maintained by the Company as collateral in connection with corporate credit cards. At September 30, 2015, the restricted cash equivalent balance was $200,000.

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants in the principal market (or, if none exists, the most advantageous market) for the specific asset or liability at the measurement date (referred to as the “exit price”). The fair value is based on assumptions that market participants would use, including a consideration of nonperformance risk. Under the accounting guidance for fair value hierarchy there are three levels of measurement inputs. Level 1 inputs are quoted prices in active markets for identical assets or liabilities. Level 2 inputs reflect input other than quoted prices included in Level 1 that are observable, either directly or through collaboration with observable market data, other than Level 1. Level 3 inputs are unobservable due to little or no corroborating market data.

The Company’s financial instruments, consisting of cash and cash equivalents, accounts receivable, accounts payable, and accrued liabilities, approximate fair value because of the short maturity of these items. Financial instruments consisting of lines of credit approximate fair value, as the interest rates associated with the lines of credit approximates the market rates for debt securities with similar terms and risk characteristics.

Changes to GAAP are established by the Financial Accounting Standards Board (“FASB”) in the form of accounting standards updates (“ASUs”) to the FASB’s Accounting Standards Codification.

In May 2014, the FASB issued ASU No. 2014-09, Revenue from Contracts with Customers (“ASU 2014-09”), which supersedes nearly all existing revenue recognition guidance under GAAP. The core principle of ASU 2014-09 is to recognize revenues when promised goods or services are transferred to customers in an amount that reflects the consideration to which an entity expects to be entitled for those goods or services. ASU 2014-09 defines a five-step process to achieve this core principle and, in doing so, more judgment and estimates may be required within the revenue recognition process than are required under existing GAAP.

The standard is effective for annual periods beginning after December 15, 2017, and interim periods therein, using either of the following transition methods: (i) a full retrospective approach reflecting the application of the standard in each prior reporting period with the option to elect certain practical expedients, or (ii) a retrospective approach with the cumulative effect of initially adopting ASU 2014-09 recognized at the date of adoption (which includes additional footnote disclosures). The Company is currently evaluating the impact of the pending adoption of ASU 2014-09 on its consolidated financial statements and has not yet determined the method by which it will adopt the standard during the year ending December 31, 2018.

In August 2014, the FASB issued ASU No. 2014-15, Disclosure of Uncertainties About an Entity’s Ability to Continue as a Going Concern. The standard requires management to perform interim and annual assessments of an entity’s ability to continue as a going concern within one year of the date the financial statements are issued and provides guidance on determining when and how to disclose going concern uncertainties in the financial statements. Certain disclosures will be required if conditions give rise to substantial doubt about an entity’s ability to continue as a going concern. ASU 2014-15 applies to all entities and is effective for annual and interim reporting periods ending after December 15, 2016, with early adoption permitted. The Company does not expect that the adoption of this standard will have a material effect on its financial statements.

In July 2015, the FASB recently issued ASU No. 2015-11, Simplifying the Measurement of Inventory (“ASU 2015-11”), as part of its simplification initiative. The standard requires inventory within the scope of ASU 2015-11 to be measured using the lower of cost and net realizable value. The changes apply to all types of inventory, except those measured using LIFO or the retail inventory method. ASU 2015-11 applies to all entities and is effective for fiscal years, and for interim periods within those fiscal years, beginning after December 15, 2016, with early adoption permitted. The Company does not expect that the adoption of this standard will have a material effect on its financial statements.

The Company currently has one stock-based compensation plan, the 2002 Stock Incentive Plan (as amended effective as of May 26, 2004, November 15, 2005, May 16, 2007, May 5, 2011, June 6, 2013, October 30, 2014 and April 27, 2015) (the “2002 Plan”), which will expire on May 5, 2019. Persons eligible to receive awards under the 2002 Plan include officers, employees, and directors of the Company, as well as consultants. As of September 30, 2015, a total of 11,550,000 shares have been authorized for issuance under the 2002 Plan, of which 3,068,000 shares of Biolase common stock have been issued pursuant to options that were exercised and restricted stock units that were settled in common stock, 5,442,000 shares of Biolase common stock have been reserved for outstanding options and unvested restricted stock units, and 3,040,000 shares of Biolase common stock remain available for future grants.

Stock-based compensation cost recognized in operating results totaled approximately $621,000 and $301,000 for the three months ended September 30, 2015 and 2014, respectively, and $2.3 million and $887,000 for the nine months ended September 30, 2015 and 2014, respectively. The net impact to earnings were $(0.01) and $(0.01) per basic and diluted share for the three months ended September 30, 2015 and 2014, respectively, and $(0.04) and $(0.02) per basic and diluted share for the nine months ended September 30, 2015 and 2014, respectively. At September 30, 2015, the Company had approximately $5.7 million of total unrecognized compensation cost, net of estimated forfeitures, related to unvested share-based compensation arrangements. The Company expects that cost to be recognized over a weighted-average period of 2.7 years.

The following table summarizes the income statement classification of compensation expense (credit) associated with share-based payments (in thousands):

	Three Months Ended					Nine Months Ended
	September 30,					September 30,

The stock option fair values, under the 2002 Plan, were estimated using the Black-Scholes option-pricing model with the following assumptions:

A summary of option activity under the 2002 Plan for the nine months ended September 30, 2015 is as follows:

						Weighted Average
				Weighted		Remaining		Aggregate
				Average		Contractual		Intrinsic
	Shares			Exercise Price		Term (Years)		Value(1)
Options outstanding at December 31, 2014		3,391,000		$	3.11		2.97	$	1,063,000
Granted		3,271,000		$	2.32

(1) The intrinsic value calculation does not include negative values. This can occur when the fair market value on the reporting date is less than the exercise price of the grant.

Cash proceeds along with fair value disclosures related to grants, exercises, and vested options under the 2002 Plan are provided in the following table (in thousands, except per share amounts):

(1) Excess tax benefits received related to stock option exercises are presented as financing cash inflows. The Company currently does not receive a tax benefit related to the exercise of stock options due to the Company’s net operating losses.

(2) The intrinsic value of stock options exercised is the amount by which the market price of the stock on the date of exercise exceeded the market price of the stock on the date of grant.

On January 2, 2015, the Compensation Committee of Biolase’s board of directors (the “Board”) granted non-qualified stock options to purchase 1,365,702 shares of Biolase common stock to six officers of the Company and one consultant in connection with the Company’s compensation plan for 2015. These options were granted at an exercise price of $2.64, the closing price of Biolase common stock on the grant date. These options expire ten years from the grant date and vest as follows: (i) as to one-half of the options, one-fourth on the first anniversary of the grant date and the remaining three-fourths, ratably over the next thirty-six month period, commencing on the thirteenth month from the grant date, and (ii) as to the other half of the options, upon the achievement of specific annual Company performance criteria. On August 12, 2015, the Compensation Committee of the Board approved a modification to the performance criteria applicable to the unvested options. As a result of this modification, the fair value of the awards decreased by $661,000, and the Company recognized additional compensation expense of $154,000 for the three and nine months ended September 30, 2015.

In accordance with the 2002 Plan, the Company issues restricted stock units (“RSUs”) to acquire shares of Biolase common stock as approved by the Board. As of September 30, 2015, 37,000 shares of Biolase common stock have been issued in connection with the settlement of the RSUs.

Effective July 13, 2015, the Compensation Committee of the Board awarded 870,000 common stock-settled RSUs to its President and Chief Executive Officer in connection with his employment agreement with the Company. The RSUs are valued at $1.64 per share and vest upon the achievement of specific interim and annual Company performance criteria.

The Company issues warrants to acquire shares of Biolase common stock underlying such warrants as approved by the Board.

A summary of warrant activity for the nine months ended September 30, 2015 is as follows:

No warrants were exercised during the three months ended September 30, 2015 or 2014 and during the nine months ended September 30, 2015. During the nine months ended September 30, 2014, Comerica Bank exercised warrants issued in connection with the Company’s prior lines of credit on a cashless basis pursuant to the terms of the warrant, resulting in a net issuance of 38,708 shares of common stock.

Effective March 9, 2015, the Compensation Committee of the Board granted non-qualified stock options to purchase up to 871,710 shares of Biolase common stock to its Chief Financial Officer in connection with his employment agreement with Biolase. These options were granted at an exercise price of $1.99 per share, the closing price of Biolase common stock on the grant date. These options expire ten years from the grant date and vest in two tranches as follows: (i) as to options to purchase 523,026 shares (the “First Tranche”), options to purchase 130,757 shares vest and become exercisable on March 9, 2016, and options to purchase 10,896 shares vest and become exercisable each month following March 9, 2016 for a period of 35 consecutive months, and options to purchase 10,909 shares vest and become exercisable on March 9, 2019, and (ii) as to options to purchase 348,684 shares (the “Second Tranche”), 248,684 of such shares vest and become exercisable on March 9, 2025. In June 2015, the Compensation Committee accelerated the vesting of 100,000 of the Second Tranche options that had previously been scheduled to vest on March 9, 2025, such that such options vested and became exercisable as of June 23, 2015. The fair value of the First Tranche of $1.48 per share was estimated using the Black-Scholes option-pricing model with assumptions of 6.1 years for expected term, 88.79% volatility and 1.83% risk-free interest rate. The fair value of the Second Tranche of $1.70 per share was estimated using the Black-Scholes option-pricing model with assumptions of 10.0 years for expected term, 87.87% volatility and 2.19% risk-free interest rate.

Effective July 13, 2015, the Compensation Committee of the Board granted non-qualified stock options to purchase up to 870,000 shares of Biolase common stock to the Company’s President and Chief Executive Officer in connection with his employment agreement with Biolase. These options were granted at an exercise price of $1.64 per share, the closing price of Biolase common stock on the grant date. These options expire ten years from the grant date and vest over four years, with options to purchase 217,500 shares vesting and becoming exercisable on July 13, 2016 and options to purchase 18,125 shares vesting and becoming exercisable each month following July 13, 2016 for a period of 36 consecutive months. The fair value of $1.19 per share was estimated using the Black-Scholes option-pricing model with assumptions of 6.1 years for expected term, 85.83% volatility and 1.93% risk-free interest rate.

Basic net loss per share is computed by dividing loss available to common stockholders by the weighted-average number of shares outstanding for the period. In computing diluted net loss per share, the weighted average number of shares of Biolase common stock outstanding is adjusted to reflect the effect of potentially dilutive securities.

Outstanding stock options and warrants to purchase 15,536,000 shares (including 9,206,000 shares underlying warrants issued in connection with the private placement completed by the Company on November 7, 2014) were not included in the computation of diluted loss per share for the three and nine months ended September 30, 2015 as a result of their anti-dilutive effect. For the same 2014 period, anti-dilutive outstanding stock options and warrants to purchase 4,703,000 shares were not included in the computation of diluted loss per share.

On July 18, 2014, the Company retired all 1,963,500 shares of stock held in treasury at that date. The Company recorded the cost of the treasury stock retired as a $2,000 reduction to common stock and a $16,397,000 reduction in additional paid in capital.

In February 2014, the Board declared a one-half percent stock dividend payable March 28, 2014, to stockholders of record on March 14, 2014. During 2015, the Board has not declared any stock dividends. There is no assurance, with respect to the amount or frequency, that any stock dividend will be declared in the future.

Inventory is valued at the lower of cost or market (determined by the first-in, first-out method) and is comprised of the following (in thousands):

Inventory is net of a provision for excess and obsolete inventory totaling $1.9 million and $2.4 million as of September 30, 2015 and December 31, 2014, respectively.

Property, plant, and equipment, net is comprised of the following (in thousands):

The cost of leasehold improvements of $114,000 and tenant improvement allowance of $398,000 in connection with the Company’s corporate headquarters and manufacturing facility lease and the costs associated with certain operating and information technology equipment of $577,000 are included in the above as part of construction in progress. For additional information on operating leases, see Note 9 of the unaudited financial statements contained in this Form 10-Q. Depreciation expense related to property, plant, and equipment totaled $251,000 and $540,000 for the three and nine months ended September 30, 2015, respectively, and $160,000 and $477,000 for the three and nine months ended September 30, 2014, respectively.

The Company conducted its annual impairment test of goodwill as of June 30, 2015 and determined that there was no impairment. The Company also tests its intangible assets and goodwill if events occur or circumstances change that would more likely than not reduce the fair value of the Company or its assets below their carrying amounts. For intangible assets subject to amortization, the Company performs its impairment test when indicators, such as reductions in demand for its products or significant economic slowdowns, are present. No events have occurred from June 30, 2015 through the date of these financial statements that have triggered further impairment testing of the Company’s intangible assets and goodwill.

Amortization expense for the three and nine months ended September 30, 2015 totaled $14,000 and $49,000, respectively, and $17,000 and $52,000, respectively, for the same periods in 2014. Other intangible assets primarily include acquired customer lists and non-compete agreements.

The following table presents details of the Company’s intangible assets, related accumulated amortization, and goodwill (in thousands):

In June 2014, the Company extended the warranty for WaterLase systems from one year to two years for systems purchased after January 1, 2014.

Current portion of deferred revenue is comprised of the following (in thousands):

In connection with the Company’s initiatives to measure and improve customer satisfaction and concurrent with the launch of WaterLase iPlus 2.0 in February 2015, the Company introduced its exclusive Practice Growth Guarantee, which is a program that essentially guarantees growth in the Company’s clients’ dental practices through training on a select number of clinical procedures and with billing and marketing support for dentists included. Consistent with the Company’s standard terms and conditions applicable to all of its products, the Practice Growth Guarantee does not give the customer the right to return purchased laser systems or receive a refund of any amount of the purchase price. However, the Practice Growth Guarantee does provide for additional training opportunities and certain billing and marketing support activities to the customer. The Company has estimated additional deferred revenue related to the Practice Growth Guarantee for all WaterLase iPlus 2.0 system sales during the nine months ended September 30, 2015 to be approximately $133,000.

During the three months ended September 30, 2014, the Company performed a review of its training service policies and procedures and determined that substantially all of the training service for new customers was used within nine months of the product purchase. Accordingly, and consistent with this information on the exhaustion of training service, the Company changed the period over which deferred training service revenue is being recognized from an estimated period of 24 months to nine months.

The Company entered into two revolving credit facility agreements with Comerica Bank (the “Credit Agreements”) on May 24, 2012. The revolving lines of credit provided for borrowings against certain domestic accounts receivable and inventory (the “Domestic Revolver”) and certain export-related accounts receivable and inventory (the “Ex-Im Revolver”).

On July 28, 2014, the Company repaid all amounts outstanding under the Credit Agreements, including principal, accrued interest, and fees which totaled, in the aggregate, approximately $2.9 million, and the Credit Agreements were terminated.

The Credit Agreements required the Company to maintain compliance with certain monthly financial and non-financial covenants, as defined therein. Any noncompliance with these covenants could have resulted in default interest rates and penalties, and Comerica Bank could have declared the amounts outstanding immediately due and payable. On March 4, 2014, the Company received a waiver of noncompliance with certain financial and nonfinancial covenants as of January 31, 2014 and December 31, 2013. In connection with this waiver, the Company incurred a fee of $10,000, and Comerica Bank reduced the total aggregate available borrowings on the lines of credit to $5.0 million. The Company was not in compliance with a financial covenant as of February 28, 2014 and, as such, entered into a forbearance agreement (the “Forbearance Agreement”) with Comerica Bank on April 10, 2014. The Company paid a fee of $10,000 in connection with the Forbearance Agreement, pursuant to which Comerica Bank reduced the total aggregate available borrowings to $4.0 million.

The Company was not in compliance with a financial covenant at March 31, 2014 and did not repay the lines of credit in full on the original maturity date of May 1, 2014. As a result, on May 5, 2014, the Company and Comerica Bank agreed to Amendment No. 1 to the Forbearance Agreement (“Amendment No. 1”), which extended the end of the forbearance period from May 1, 2014 to June 1, 2014. In connection with Amendment No. 1, the maturity date of the revolving lines of credit was extended to June 1, 2014, and the Company paid an administrative fee of $10,000. On June 3, 2014, the Company and Comerica Bank agreed to Amendment No. 2 to Forbearance Agreement (“Amendment No. 2”), which extended the maturity date of the revolving lines of credit to August 1, 2014. In connection with Amendment No. 2, Comerica Bank increased the interest rates on the lines of credit by 0.50%, and the Company paid an administrative fee of $15,000. The Company was not in compliance with certain financial covenants as of May 31, 2014 and, as a result, agreed to Amendment No. 3 to Forbearance Agreement with Comerica Bank whereby the forbearance period was continued to August 1, 2014, and the Company paid an administrative fee of $10,000.

The outstanding principal balances of the Credit Agreements, as amended June 3, 2014, bore interest at annual percentage rates equal to the daily prime rate, plus 2.50% for the Domestic Revolver and 2.00% for the Ex-Im Revolver. The daily prime rate was subject to a floor of the daily adjusting LIBOR rate plus 2.50% per annum, or if LIBOR was undeterminable, 2.50% per annum. The Company was also required to pay an unused commitment fee of 0.25% based on a portion of the undrawn lines of credit, payable quarterly in arrears. During the three and nine months ended September 30, 2014, the Company incurred $37,000 and $451,000, respectively, of interest expense associated with the credit facilities, including $0 and $128,000, respectively, of amortization of deferred debt issuance costs and $0 and $200,000, respectively, of amortization of the discount on lines of credit. There was no interest expense payable at December 31, 2014.

Lockbox arrangements under the revolving bank facilities provided that substantially all of the income generated was deposited directly into lockbox accounts and then swept into cash management accounts for the benefit of Comerica Bank. Cash was disbursed from Comerica Bank to the Company only after payment of the applicable debt service and principal. At December 31, 2014, there were no restricted cash amounts. The Company’s obligations were generally secured by substantially all of the Company’s assets then owned or thereafter acquired.

During the three and nine months ended September 30, 2014, the Company incurred $10,000 and $55,000, respectively, of Comerica Bank commitment fees and legal costs associated with the various waivers and amendments. Commitment fees and legal costs associated with acquiring and maintaining the credit facilities were capitalized and amortized on a straight-line basis as interest expense over the remaining term of the Credit Agreements.

The Company leases its corporate headquarters and manufacturing facility in Irvine, California and also leases certain other facilities, office equipment, and automobiles under various operating or capital lease arrangements. In February 2015, the Company entered into a 30-month capital lease agreement for information technology equipment. Future minimum lease payments under the capital lease, together with the present value of the net minimum lease payments, for the years ending December 31, 2015, 2016 and 2017 are $32,000, $157,000, and $160,000, respectively. The amount necessary to reduce net minimum lease payments to present value calculated at the Company's incremental borrowing rate of 1.64% at the inception of the lease totaled $9,000. The present value of net minimum lease payments are reflected on the Consolidated Balance Sheets as current and noncurrent obligations of $142,000 within accrued liabilities and $201,000 within capital lease obligation, respectively.

In March 2015, the corporate headquarters and manufacturing facility lease was amended to extend the term through April 30, 2020, modify provisions for tenant improvement allowance of up to $398,000, and adjust the basic rent terms. Future minimum rental commitments under operating lease agreements with non-cancelable terms greater than one year for the years ending December 31, 2015, 2016, 2017, and 2018 and thereafter totaled $178,000, $694,000, $651,000, and $1.5 million, respectively.

Certain members of management are entitled to severance benefits payable upon termination following a change in control, which would approximate $1.6 million, in the aggregate, at September 30, 2015. The Company also has agreements with certain employees to pay bonuses based on targeted performance criteria. As of September 30, 2015, approximately $198,000 was accrued for performance bonuses, which is included in accrued liabilities in the consolidated balance sheets.

The Company generally purchases components and subassemblies for its products from a limited group of third party suppliers through purchase orders. As of September 30, 2015, the Company had $11.0 million of purchase commitments for which the Company has not received certain goods or services that are expected to be purchased within one year. These purchase commitments were made to secure better pricing and to ensure the Company will have the necessary parts to meet anticipated near-term demand.

The Company discloses material loss contingencies deemed to be reasonably possible and accrues for loss contingencies when, in consultation with its legal advisors, management concludes that a loss is probable and reasonably estimable. The ability to predict the ultimate outcome of such matters involves judgments, estimates, and inherent uncertainties. The actual outcome of such matters could differ materially from management’s estimates.

On August 23, 2013, a purported class action lawsuit entitled Brady Adams v. Biolase, Inc., et al., Case No. 13-CV-1300 JST (FFMx) was filed in the United States District Court for the Central District of California against Biolase, its then Chief Executive Officer, Federico Pignatelli, and its then Chief Financial Officer, Frederick D. Furry. On August 26, 2013, a purported class action lawsuit entitled Ralph Divizio v. Biolase, Inc., et al., Case No. 13-CV-1317 DMG (MRWx) was filed in the same court against Biolase, Messrs. Pignatelli and Furry, and its then President and Chief Operating Officer, Alexander K. Arrow. Each of the lawsuits alleges violations of the federal securities laws and asserts causes of action against the defendants under Sections 10(b) and 20(a) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). In accordance with the Private Securities Litigation Reform Act of 1995, on December 10, 2013, the court entered an order consolidating the lawsuits, appointing a lead plaintiff and approving the lead plaintiff’s selection of lead counsel. On February 24, 2014, the lead plaintiff filed a consolidated complaint against the Company and Messrs. Pignatelli, Furry, and Arrow, alleging violations of the federal securities laws and asserting causes of action against the defendants under Sections 10(b) and 20(a) of the Exchange Act.

On November 19, 2013, the Board received a letter from attorneys for purported shareholder David T. Long, demanding that the Board investigate, institute litigation, and take measures to redress and prevent alleged wrongdoing concerning the dissemination of certain allegedly false and misleading public disclosures made by the Company between January 2013 and August 2013.

On June 5, 2015, the United States District Court for the Central District of California approved, on a preliminary basis, the settlement of the consolidated securities class action lawsuit. On October 13, 2015, the court granted final approval of the settlement, and ordered the plaintiff to submit a proposed final judgment consistent with the court’s approval. On October 30, 2015, the court entered final judgment which formally released all claims against the Company. As of the date of these financial statements, management does not expect the Company to incur additional expenses related to this matter due to certain insurance coverage in place.

On April 24, 2012, CAO Group, Inc. (“CAO”) filed a lawsuit against the Company in the District of Utah for patent infringement of U.S. Patent No. 7,485,116 (the “116 Patent”) regarding the Company’s ezlase dental laser. On September 9, 2012, CAO filed its First Amended Complaint, which added claims for (1) business disparagement/injurious falsehood under common law and (2) unfair competition under 15 U.S.C. Section 1125(a). The additional claims stem from a press release that the Company issued on April 30, 2012, which CAO claims contained false statements that are disparaging to CAO and its diode product. The First Amended Complaint seeks injunctive relief, treble damages, attorneys’ fees, punitive damages, and interest. On November 13, 2012, the Court stayed the lawsuit for 120 days to allow the United States Patent and Trademark Office (the “USPTO”) to consider the Company’s request for reexamination of the patent-in-suit. The USPTO granted the request to reexamine the asserted claims of the patent-in-suit and, on February 28, 2013, the Court stayed the lawsuit until the termination of the reexamination proceedings. On April 23, 2013, the USPTO issued an office action rejecting all of the asserted claims over the prior art, and CAO responded to the office action. On August 28, 2013, the USPTO issued an Action Closing Procedure, rejecting all of CAO’s patent claims. CAO responded to the USPTO’s ruling and on December 10, 2013, the USPTO issued a Right of Appeal Notice, finally rejecting some claims of the 116 Patent while finding that other claims appeared to be patentable. The Company appealed the USPTO’s findings on January 9, 2014 and on January 27, 2014, the USPTO declined to reconsider the finding of certain claims as patentable and instructed the parties to proceed to appeal to the Patent Trial and Appeal Board. On March 17, 2014, the Company filed its brief in support of its appeal of the USPTO’s decision not to reject certain claims of the 116 Patent. On March 24, 2014, CAO filed its brief in support of its appeal of the USPTO’s decision to reject certain claims of the 116 patent. On April 18, 2014, the Company filed a respondent brief in opposition to the CAO’s appeal arguments. On May 30, 2014, both parties filed rebuttal briefs in support of their appeals. On June 30, 2014, the Company requested an oral hearing before the Board. On July 1, 2014, the Board noted that request and docketed the case for consideration. A hearing on reconsideration was held in November 2014. The Patent Trial and Appeal Board issued its Decision on Appeal on July 1, 2015. The Decision on Appeal rejected 38 of 42 patent claims. Accordingly, CAO filed a Request for Rehearing on July 31, 2015.

The Company filed a patent infringement lawsuit against Fotona Proizvodnja Optoelektronskih Naprav D.D. and Fotona LLC (collectively, “Fotona”) in Düsseldorf District Court (the “Düsseldorf Court”) on April 12, 2012 alleging infringement with respect to the Fotona Fidelis dental laser system. Fotona denies liability and seeks the reimbursement of statutory fees from the Company. Together with its response brief, Fotona also filed a nullity action against the patent in dispute, patent number EP 1 560 470. The nullity action is pending at the German Federal Patent Court (the “Patent Court”), Docket No. 1 Ni 58/13 (EP). On September 2, 2013, the Company filed its counterplea in the infringement proceedings and phrased its arguments defending the validity of the patent. These arguments were also the subject of the defense brief to the Patent Court in the parallel nullity action proceedings. On September 9, 2013, the Company filed its response to the Patent Court. Fotona filed a rejoinder on February 3, 2014, including its counterplea on nullity.

On April 29, 2014, the Düsseldorf Court rendered a first instance decision whereby Fotona must cease and desist from selling its Fidelis and Lightwalker dental laser systems, render accounts on past sales, recall respective products, and pay damages on infringement. Additionally, the Company was awarded statutory fees, court costs, and attorney fees. Preliminary enforcement against Fotona is possible if the Company posts a bond totaling €500,000, which is designed to cover a portion of the potential damages, before a final instance decision is available. In Germany, damages can be calculated based on the profits made by the infringer after the formal announcement of the granting of a patent, in this case beginning January 1, 2009, without considering direct labor or any other operational costs. However, Fotona has yet to provide the details of its profits in order to allow the Company to calculate the damages. In the two additional first instance cases following the extension of the initial lawsuit against Fotona, the Düsseldorf Court also required the Company to provide a statutory bond totaling €146,000. Such bonds are traditionally imposed on foreign plaintiffs to cover all statutory, court, and attorney’s fees. Fotona submitted its responses to the action and filed respective invalidation actions against the rights of the Company.

Subsequent to the foregoing responses, on March 24, 2015 the parties reached an agreement to settle the foregoing litigation and to dismiss the litigation with prejudice. As part of the settlement, Fotona agreed to pay the Company a total of $1.4 million, with $550,000 payable within 10 days of March 24, 2015 and the remaining, $825,000 payable in three increments of $275,000 each to be paid no later than the first, second, and third anniversary of the effective date of the agreement. Pursuant to the settlement agreement, the Company (i) granted Fotona a three-year, non-exclusive, paid-up license in the United States market and a five-year, non-exclusive, paid-up license in markets outside of the United States and (ii) agreed to grant Fotona a non-exclusive, royalty-based license following the expiration of the paid-up licenses. The Company calculated the present value of the settlement amount to be $1.2 million and allocated such amount to each significant element of the settlement on a relative fair value basis. $731,000 and $68,000 was allocated towards the recovery of the Company’s legal expenses and as settlement for the dismissal of the patent infringement lawsuit and are reflected as legal settlement and license fees and royalty revenue, respectively, on the Consolidated Statements of Operations and Comprehensive Loss. The remaining amount of $379,000 was allocated towards the three-year, non-exclusive, paid-up license in the United States market and the five-year, non-exclusive, paid-up license in markets outside of the United States which was reflected within other assets and long-term deferred revenue on the Consolidated Balance Sheets. The deferred revenue is being recognized as license revenue over the terms of the paid-up licenses.

In the normal course of business, the Company may be subject to other legal proceedings, lawsuits, and other claims. Although the ultimate aggregate amount of probable monetary liability or financial impact with respect to these matters is subject to many uncertainties and is therefore not predictable with assurance, the Company’s management believes that any monetary liability or financial impact to the Company from these other matters, individually and in the aggregate, would not be material to the Company’s financial condition, results of operations, or cash flows. However, there can be no assurance with respect to such result, and monetary liability or financial impact to the Company from these other matters could differ materially from those projected.

The Company currently operates in a single reportable segment. For the three and nine months ended September 30, 2015, sales in the United States accounted for approximately 59% and 59% of net revenue, respectively, and international sales accounted for approximately 41% and 41% of net revenue, respectively. For the three and nine months ended September 30, 2014, sales in the United States accounted for approximately 66% and 62% of net revenue, respectively, and international sales accounted for approximately 34% and 38% of net revenue, respectively.

Net revenue by geographic location based on the location of customers was as follows (in thousands):

No individual country, other than the United States, represented more than 10% of total net revenue.

Long-lived assets located outside of the United States at our foreign subsidiaries totaled $339,000 and $374,000 as of September 30, 2015 and December 31, 2014, respectively.

Revenue from the Company’s products for the three and nine months ended September 30, 2015 and 2014 are as follows:

	Three Months Ended						Nine Months Ended
	September 30						September 30
	2015			2014			2015			2014
Laser systems		65.3	%		57.9	%		65.2	%		60.2	%
Imaging systems		6.4	%		11.0	%		4.7	%		9.5	%
Consumables and other		13.1	%		12.6	%		15.5	%		13.6	%
Services		14.9	%		18.2	%		14.1	%		16.3	%
License fees and royalties		0.3	%		0.3	%		0.5	%		0.4	%
Total revenue		100.0	%		100.0	%		100.0	%		100.0	%

No individual customer represented more than 10% of the Company’s revenue for the three and nine months ended September 30, 2015 or 2014.

The Company maintains its cash and cash equivalent accounts with established commercial banks. Such cash deposits periodically exceed the Federal Deposit Insurance Corporation insured limit.

As of September 30, 2015, one customer represented 11.4% of the Company’s accounts receivable. Amounts due are expected to be collected in full by the Company. No individual customer represented more than 10% of the Company’s accounts receivable at December 31, 2014.

The Company currently purchases certain key components of its products from single suppliers. Although there are a limited number of manufacturers of these key components, management believes that other suppliers could provide similar key components on comparable terms. A change in suppliers, however, could cause delays in manufacturing and a possible loss of sales, which could adversely affect the Company’s business, results of operations, and financial condition.

The Company accounts for income taxes under the asset and liability method, whereby 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 apply 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. Management evaluates the need to establish a valuation allowance for deferred tax assets based upon the amount of existing temporary differences, the period in which they are expected to be recovered, and expected levels of taxable income. A valuation allowance to reduce deferred tax assets is established when it is “more likely than not” that some or all of the deferred tax assets will not be realized. Based on the Company’s net losses in prior years, management has determined that a full valuation allowance against the Company’s net deferred tax assets is appropriate.

Accounting for uncertainty in income taxes prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a tax position taken or expected to be taken in a tax return and provides guidance on de-recognition, classification, interest and penalties, accounting in interim periods, disclosure, and transition. The Company has elected to classify interest and penalties as a component of its income tax provision. With respect to the liability for unrecognized tax benefits, including related estimates of penalties and interest, the Company did not record a liability for unrecognized tax benefits for the three and nine months ended September 30, 2015 and 2014, respectively. The Company does not expect any changes to its unrecognized tax benefit for the next twelve months that would materially impact its consolidated financial statements.

During the three and nine months ended September 30, 2015, the Company recorded an income tax provision of $44,000 and $127,000, respectively, resulting in an effective tax rate of (0.8)% and (0.7)%, respectively. During the three and nine months ended September 30, 2014, the Company recorded an income tax provision of $28,000 and $81,000, respectively, resulting in an effective tax rate of (0.8)% and (0.6)%, respectively. The income tax provisions for the three and nine months ended September 30, 2015 and 2014 were calculated using the discrete year-to-date method. The effective tax rate differs from the statutory tax rate of 34% primarily due to the existence of valuation allowances against net deferred tax assets and current liabilities resulting from the estimated state income tax liabilities and federal alternative minimum tax liability.

We have clearance from the U.S. Food and Drug Administration (the “FDA”) to market and sell our laser systems in the United States and also have the necessary registrations to market and sell our laser systems in Canada, the European Union, and many other countries outside the U.S. Additionally, our in-licensed imaging equipment and related products improve diagnoses, applications, and procedures in dentistry and medicine.

We offer two categories of laser system products: WaterLase (all-tissue) systems and Diode (soft-tissue) systems. Our flagship brand, the WaterLase, uses a patented combination of water and laser energy to perform most procedures currently performed using drills, scalpels, and other traditional dental instruments for cutting soft and hard tissue. We also offer our Diode laser systems to perform soft tissue, pain therapy, and cosmetic procedures, including teeth whitening. As of September 30, 2015, we had approximately 260 issued and 100 pending U.S. and international patents, the majority of which are related to WaterLase technology. From 1998 through September 30, 2015, we sold approximately 29,700 laser systems in over 80 countries around the world. Contained in this total are approximately 11,100 WaterLase systems, including over 7,000 WaterLase MD and iPlus systems.

Our WaterLase systems precisely cut hard tissue (teeth and bone) and soft tissue (gums) with clinically superior results to surrounding tissue and dental structures as compared to scalpels or other conventional instruments. Our Diode systems are designed to complement our WaterLase systems and are used in soft tissue procedures, pain therapy, hygiene, and cosmetic applications, including teeth whitening. The Diode systems, together with our WaterLase systems, offer practitioners a broad product line with a range of features and price points.

We also manufacture and sell consumable products and accessories for our laser systems. Our WaterLase and Diode systems use disposable laser tips of differing sizes and shapes depending on the procedure being performed. We also market flexible fibers and hand pieces that dental practitioners replace periodically after initially purchasing our laser systems.

Due to the limitations associated with traditional and alternative dental instruments, we believe there is a large market opportunity for all-tissue dental laser systems that provide superior clinical outcomes, help reduce trauma, pain, and discomfort associated with dental procedures, and increase patient acceptance for treatment protocols. We also believe there is market opportunity for digital radiography systems that improve the accuracy of diagnosis, leading to superior treatment planning, and healthier outcomes for patients.

Our strategy is to increase awareness and demand for (i) our products among dental practitioners by creating value to growing dentist practices and (ii) our laser systems among patients through educational programs about the clinical benefits of the WaterLase and Diode Systems. An important goal of ours is to increase consumables revenue by selling more single-use accessories used by dental practitioners when performing procedures using our dental laser systems. In the short-term, we are striving for operating excellence through lean enterprise initiatives, with a specific focus on our sales strategy and cash flow management, coupled with optimizing our engineering capabilities to develop innovative new products.

We also seek to create value through innovation and leveraging existing technologies into adjacent medical applications. In addition, we seek to expand our product line and clinical applications by developing enhancements and transformational innovations, including new clinical solutions for dental applications and for other adjacent medical applications. We are actively exploring some medical markets, and we plan to continue to explore potential collaborations in the future to extend the use of our proprietary laser technologies to other medical applications.

Consistent with our goal to refocus our energies on strengthening leadership, worldwide competitiveness and attention to our professional customers and their patients, we announced the appointment of a new Chief Financial Officer in March 2015 and a new President and Chief Executive Officer in July 2015. Collectively, they bring with them to Biolase decades of experience and expertise in the medical device, dental and healthcare fields. In September 2015, we completed a series of internal corporate organizational restructuring activities where we streamlined operations and reduced payroll, payroll-related and consulting-related expenses by approximately $2.4 million, net, on an annualized basis. Expenses related to this restructuring during the quarter ended September 30, 2015 totaled approximately $246,000. We will begin to realize the impact of these cost-saving measures in the fourth quarter of 2015 and throughout 2016.

In February 2015, we launched the WaterLase iPlus 2.0, our next generation minimally invasive all-tissue flagship laser, along with our exclusive Practice Growth Guarantee. The latter essentially guarantees growth in our clients’ dental practices through focused training on a select number of clinical procedures and with billing and marketing support for dentists included. In November 2015, we announced an upgrade to the WaterLase iPlus 2.0 to provide dental practitioners a clinical protocol and application to assist in the effective management of peri-implantitis. A growing problem in dentistry, peri-implantitis is a destructive inflammatory process affecting the soft and hard tissues surrounding dental implants. With the addition of the new clinical protocol, the WaterLase iPlus 2.0 now provides pre-programmed settings and step-by-step applications for more than 50 procedures and clinical indications.

The WaterLase iPlus 2.0 includes innovations and improvements designed to enhance patients’ and dentists’ experiences and generate practice growth for dental practitioners through routine use. During the second quarter of 2015, the Practice Growth Guarantee program was fully implemented in the United States. By partnering with our WaterLase iPlus 2.0 customers via the Practice Growth Guarantee program, we are actively and routinely soliciting feedback, providing them and us highly valuable information.

The WaterLase iPlus 2.0 also marks the debut of the SureFire YSGG Delivery System, which ensures greater uptime through enhanced precision, performance and reliability. Building on the gold standard for comfortable laser delivery systems, SureFire has redesigned optics that efficiently deliver precise laser energy with a replaceable, disposable shield for better dependability. Still the most flexible, tension-free delivery system available, SureFire offers improved clinical access and comfort with its minimally-invasive flagship dental laser system and exclusive contra-angle hand-piece. The significance of these improvements has been confirmed by positive feedback from new and existing customers alike, who have indicated that Surefire meets or exceeds their expectations for reliability.

In December 2014, we introduced the EPIC X diode laser, an enhanced soft-tissue laser system featuring upgrades and improvements from our EPIC 10, which was released in 2012. EPIC X includes enhancements to nearly every system component to optimize treatment speed and efficiency, including pre-initiated diode tips, allowing dentists to significantly reduce procedure time. In the second quarter of 2015, we saw an increase in demand for EPIC X, solidifying our leadership position in this category. Dentists, hygienists, office staff, and patients are experiencing the clinical benefits provided by the EPIC X.

The unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) which require us to make estimates and assumptions that affect the reported amounts of assets and liabilities at the date of the consolidated financial statements and revenues and expenses reported during the period. Information with respect to our critical accounting policies that we believe could have the most significant effect on our reported results and require subjective or complex judgments by management is contained in Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, of the 2014 Form 10-K. We believe that there have been no significant changes during the nine months ended September 30, 2015 in our critical accounting policies from those disclosed in Item 7 of the 2014 Form 10-K, except as disclosed in Note 2 of the unaudited financial statements in this Form 10-Q.

The following table sets forth certain data from our consolidated statements of operations expressed as percentages of net revenue:

	Three Months Ended						Nine Months Ended
	September 30,						September 30,

In addition to the financial information prepared in conformity with GAAP, we provide non-GAAP net loss financial information. Management believes that the presentation of non-GAAP net loss assists investors in making comparisons of period-to-period operating results and that, in some respects, this non-GAAP financial measure is more indicative of the Company’s ongoing core operating performance than its GAAP equivalent.

Management also believes that the presentation of non-GAAP net loss provides investors with greater transparency and facilitates comparison of operating results across a broad spectrum of companies with varying capital structures, compensation strategies, derivative instruments, and amortization methods, which provide a more complete understanding of our financial performance, competitive position, and prospects for the future. However, non-GAAP net loss information presented in this report has certain limitations in that it does not reflect all of the costs associated with the operations of our business as determined in accordance with GAAP. Therefore, investors should consider non-GAAP net loss in addition to, and not as a substitute for, or as superior to, measures of financial performance prepared in accordance with GAAP. Further, non-GAAP net loss presented by the Company may be different from non-GAAP net loss used by other companies.

Management uses non-GAAP net loss (defined as net loss before interest, taxes, depreciation and amortization, stock-based compensation, other equity instruments, and other non-cash compensation) in its evaluation of the Company’s core results of operations and trends between fiscal periods and believes that these measures are important components of its internal performance measurement process. Management believes that this non-GAAP financial information reflects an additional way of viewing aspects of our business that, when viewed with our GAAP results, provides a more complete understanding of factors and trends affecting our business. The following table contains a reconciliation of non-GAAP net loss to GAAP net loss (in thousands).

Net revenue by geographic location based on the location of customers, including each category’s percentage of our total revenue, for the three months ended September 30, 2015 and 2014, as well as the amount of change and percentage of change in each geographic revenue category, was as follows (dollars in thousands):

	Three Months Ended				Three Months Ended
	September 30,				September 30,				Amount			Percent
	2015				2014				Change			Change
United States	$	6,598	58.7	%	$	8,367	65.8	%	$	(1,769	)		(21.1	%)
International		4,636	41.3	%		4,347	34.2	%		289			6.6	%
Net revenue	$	11,234	100.0	%	$	12,714	100.0	%	$	(1,480	)		(11.6	%)

The overall decrease in quarter-over-quarter net revenue resulted from decreases in domestic imaging systems net revenue, domestic and international services net revenue, consumables and other net revenue, and domestic license fees and royalty revenue. Laser systems revenue remained relatively unchanged for Third Quarter 2015 with a decrease of approximately $20,000, or 0.3%, compared to Third Quarter 2014. We continued to focus our energies on strengthening leadership, worldwide competitiveness and attention to our professional customers and their patients in Third Quarter 2015. The third quarter is typically a relatively lower revenue quarter as dental practitioners take summer vacations throughout the United States and Europe, limiting our effective selling days. While revenue generated from sales of our flagship WaterLase laser systems decreased by 4.8% worldwide, we are encouraged by revenue generated from our diode laser systems, which increased 11.3% worldwide when compared to Third Quarter 2014.

Imaging systems net revenue decreased by approximately $682,000, or 48.6%, in Third Quarter 2015 compared to Third Quarter 2014. The decrease in net revenue from imaging systems is attributable to our continuous primary focus on our flagship WaterLase laser systems.

Consumables and other net revenue, which includes consumable products such as disposable tips, decreased by approximately $131,000, or 8.2%, in Third Quarter 2015 compared to Third Quarter 2014. This decrease in consumables and other net revenue was primarily a result of seasonality and timing of customer sales.

Services net revenue, which consists of extended warranty service contracts, advanced training programs, and other services, decreased by approximately $640,000, or 27.6%, for Third Quarter 2015, as compared to Third Quarter 2014. The decrease consists of a net revenue increase of approximately $68,000, or 4.2%, during Third Quarter 2015 and a decrease resulting from a change in accounting estimate of approximately $708,000 during the Third Quarter 2014 related to changing our revenue recognition for deferred training service revenue from 24 months to nine months. The slight net revenue increase is primarily due to sales of laser systems, leading to increased demand for our training courses and the recognition of deferred revenue associated with the Practice Growth Guarantee program.

License fees and royalty revenue decreased by approximately $7,000, or 17.1%, to $34,000 in Third Quarter 2015 compared to $41,000 for Third Quarter 2014. License fees and royalty revenue are attributable to intellectual property related to our laser technologies and past-due royalty revenue recovered in connection with our patent infringement lawsuit settlement. For a detailed discussion of the intellectual property litigation and related settlement, see Note 9 of the unaudited financial statements contained in this Form 10-Q.

Cost of Revenue and Gross Profit: The following table summarizes our cost of revenue and gross profit for the three months ended September 30, 2015 and 2014, as well as the amount of change and percentage of change (dollars in thousands):

	Three Months Ended				Three Months Ended
	September 30,				September 30,				Amount			Percent
	2015				2014				Change			Change
Net revenue	$	11,234	100.0	%	$	12,714	100.0	%	$	(1,480	)		(11.6	%)
Cost of revenue		7,853	69.9	%		7,321	57.6	%		532			7.3	%
Gross profit	$	3,381	30.1	%	$	5,393	42.4	%	$	(2,012	)		(37.3	%)

Gross profit as a percentage of revenue typically fluctuates with product and regional mix, selling prices, material costs and revenue levels. The decrease in gross profit as a percentage of revenue for Third Quarter 2015, as compared to Third Quarter 2014, was mainly attributable to increased promotions related to the launch of EPIC X and WaterLase iPlus 2.0 and the impact from the recognition of $708,000 in deferred training service revenues resulting from a change in estimate during Third Quarter 2014.

Operating Expenses: The following table summarizes our operating expenses as a percentage of net revenue for the three months ended September 30, 2015 and 2014, as well as the amount of change and percentage of change (dollars in thousands):

	Three Months Ended				Three Months Ended
	September 30,				September 30,				Amount			Percent
	2015				2014				Change			Change
Sales and marketing	$	4,039	36.0	%	$	3,862	30.4	%	$	177			4.6	%
General and administrative		2,860	25.5	%		3,474	27.3	%		(614	)		(17.7	%)
Engineering and development		1,756	15.6	%		1,276	10.0	%		480			37.6	%
Excise tax		78	0.7	%		76	0.6	%		2			2.6	%
Total operating expenses	$	8,733	77.8	%	$	8,688	68.3	%	$	45			0.5	%

The quarter-over-quarter change in operating expense is explained in the following expense categories:

Sales and Marketing Expense. The increase to sales and marketing expense was primarily a result of increased payroll and consulting-related expenses of $318,000, partially offset by decreased commissions of $84,000. The increase to payroll and consulting-related expenses (i) is attributable to the increased headcount in our sales and marketing team domestically and internationally for most of Third Quarter 2015 and (ii) includes an increase of $158,000 in severance-related expenses associated with our internal corporate organizational restructuring activities.

General and Administrative Expense. The decrease to general and administrative expense was primarily due to decreased legal expenses of $1.2 million and decreased investor relations expenses of $230,000, partially offset by increased payroll and consulting-related expenses of $680,000. The decrease in legal expenses resulted from the atypical defense of the director dispute and resulting shareholder litigation incurred during Third Quarter 2014. The decrease in investor relations expenses is due to the timing of our annual shareholder meeting, which was held in April of 2015 compared to August of 2014. The increase in payroll and consulting-related expenses resulted primarily from an increase of $432,000 in stock-based compensation primarily attributable to grants to existing and new employees.

Engineering and Development Expense. The increase to engineering and development expense was primarily due to increased payroll, consulting and temporary labor expenses of $253,000, and increased operating supplies cost of $58,000, resulting from our focused efforts to accelerate innovation of both our existing products and technologies as well as to develop new products and technologies, which we believe will further strengthen our worldwide leadership position. Our engineering and development expenses fluctuate as our specific programs supporting product development transition from one development phase to the next. Depending on the stage of completion and level of effort related to each development phase we undertake, we may experience variations in our engineering and development expense. We expense engineering and development expenses as they are incurred.

Excise Tax Expense. The Patient Protection and Affordable Care Act imposes a 2.3% medical device excise tax on certain product sales to customers located in the U.S. We incurred excise tax expenses of $78,000, or 0.7% of net revenue, for Third Quarter 2015 as compared to $76,000, or 0.6% of net revenue, for Third Quarter 2014. The slight increase of $2,000, or 2.6%, in excise tax expense was due to increased non-exempt laser systems sales in the United States of approximately $74,000 in Third Quarter 2015 when compared to Third Quarter 2014.

Gain (loss) on Foreign Currency Transactions. We realized a $32,000 gain on foreign currency transactions for Third Quarter 2015, compared to a $135,000 loss on foreign currency transactions for Third Quarter 2014 due to exchange rate fluctuations between the U.S. dollar and other currencies, primarily the Euro.

Interest Income (Expense), Net. Interest income for Third Quarter 2015 represents interest recognized from the discounted present value of the settlement in connection with the Fotona intellectual property litigation, as described in Note 9 of the unaudited financial statements contained in this Form 10-Q. Interest expense for Third Quarter 2015 consists of interest incurred on our capital lease obligations in connection with the lease of information technology equipment. Interest expense for Third Quarter 2014 consisted primarily of interest on our revolving credit facilities and amortization of debt issuance costs and debt discount. Interest income (expense), net totaled approximately $21,000 of income, or 0.2% of net revenue, for Third Quarter 2015, as compared to $37,000 of interest expense for Third Quarter 2014. The decrease was primarily a result of the Company paying down all amounts due under the revolving lines of credit with Comerica Bank in July 2014.

Income Tax Provision. We use a discrete year-to-date method in calculating quarterly provision for income taxes. Our provision for income taxes was $44,000 for Third Quarter 2015, compared to a provision of $28,000 for Third Quarter 2014. The increase of $16,000, or 57.1%, in income tax provision was primarily due to increased international sales revenue, which accounted for $4.6 million of net revenue in Third Quarter 2015 and $4.3 million of net revenue in Third Quarter 2014. For additional information regarding income taxes, see Note 12 of the unaudited financial statements contained in this Form 10-Q.

Net Loss. Our net loss totaled approximately $5.3 million for Third Quarter 2015 compared to a net loss of $3.5 million for Third Quarter 2014. The increase in net loss of approximately $1.8 million, or 52.9%, was primarily due to a decrease in gross profit of $2.0 million, partially offset by an increase to total non-operating income (loss), net of $225,000.

Net Revenue: The following table summarizes our net revenues by category, including each category’s percentage of our total revenue, for the nine months ended September 30, 2015 and 2014, as well as the amount of change and percentage of change in each revenue category (dollars in thousands):

	Nine Months Ended				Nine Months Ended
	September 30,				September 30,				Amount			Percent

Net revenue	$	33,958	100.0	%	$	34,418	100.0	%	$	(460	)		(1.3	)	%

Net revenue by geographic location based on the location of customers, including each category’s percentage of our total revenue, for the nine months ended September 30, 2015 and 2014, as well as the amount of change and percentage of change in each geographic revenue category, was as follows (dollars in thousands):

	Nine Months Ended				Nine Months Ended
	September 30,				September 30,				Amount			Percent
	2015				2014				Change			Change
United States	$	19,914	58.6	%	$	21,404	62.2	%	$	(1,490	)		(7.0	)	%
International		14,044	41.4	%		13,014	37.8	%		1,030			7.9		%
Net revenue	$	33,958	100.0	%	$	34,418	100.0	%	$	(460	)		(1.3	)	%

The overall decrease in period-over-period net revenue resulted from decreases in domestic imaging systems net revenue and services revenue, partially offset by increases in domestic and international laser system net revenue, consumables and other net revenue and license fees and royalty revenue. Laser systems revenue increased by approximately $1.4 million, or 6.8%, while net revenue from imaging systems decreased by approximately $1.7 million or 51.6%. The period-over-period decrease in net revenue also resulted from a decrease in services net revenue due to a change in accounting estimate of approximately $708,000 recognized in Third Quarter 2014 related to a change in the period for recognizing deferred training service revenue from 24 to nine months. This was partially offset by an increase in consumables and other net revenue and license fees and royalty revenue.

As we continued building our worldwide leadership position in dental lasers by providing the best-in-class products and services to our professional customers and their patients, we have reversed the historical trend of declining WaterLase sales. For the nine months ended September 30, 2015, revenue generated from sales of our flagship WaterLase laser systems increased by 9.9% worldwide when compared to the same period in 2014, including increases of 8.0% and 12.2% for domestic and international sales, respectively. Period-over-period revenue generated from sales of our diode laser systems increased by 1.4% worldwide, including an increase of 14.9% for domestic sales and a decrease of 6.4% for international sales.

Consumables and other net revenue, which includes consumable products such as disposable tips, increased by approximately $598,000, or 12.8%, period-over-period. This increase in consumables and other net revenue was primarily a result of continued auxiliary sales to our growing laser customer base.

Services net revenue, which consists of extended warranty service contracts, advanced training programs, and other services, decreased by approximately $819,000, or 14.6%, period-over-period. The decrease was primarily due to the impact from the recognition of $708,000 in deferred training service revenues resulting from a change in estimate in the period over which deferred training service revenue is being recognized and the extension of our warranty for WaterLase systems from one year to two years for systems purchased after January 1, 2014, during the nine months ended September 30, 2014.

License fees and royalty revenue increased by approximately $46,000, or 36.5%, period-over-period. License fees and royalty revenue are attributable to intellectual property related to our laser technologies and past-due royalty revenue recovered in connection with our patent infringement lawsuit settlement. For a detailed discussion of the intellectual property litigation and related settlement, see Note 9 of the unaudited financial statements contained in this Form 10-Q.

Cost of Revenue and Gross Profit: The following table summarizes our cost of revenue and gross profit for the nine months ended September 30, 2015 and 2014, as well as the amount of change and percentage of change (dollars in thousands):

	Nine Months Ended				Nine Months Ended
	September 30,				September 30,				Amount			Percent
	2015				2014				Change			Change
Net revenue	$	33,958	100.0	%	$	34,418	100.0	%	$	(460	)		(1.3	)	%

Gross profit	$	10,292	30.3	%	$	13,063	38.0	%	$	(2,771	)		(21.2	)	%

Gross profit as a percentage of revenue typically fluctuates with product and regional mix, selling prices, material costs and revenue levels. The decrease in gross profit as a percentage of revenue for the nine months ended September 30, 2015, as compared to the nine months ended September 30, 2014 was mainly attributable to increased promotions related to the launch of EPIC X and WaterLase iPlus 2.0 and the impact from the recognition of $708,000 in deferred training service revenues resulting from a change in estimate during Third Quarter 2014.

Operating Expenses: The following table summarizes our operating expenses as a percentage of net revenue for the nine months ended September 30, 2015 and 2014, as well as the amount of change and percentage of change (dollars in thousands):

The period-over-period change in operating expense is explained in the following expense categories:

Sales and Marketing Expense. The increase to sales and marketing expense was primarily a result of increased media and advertising expenses of $521,000 and increased payroll and consulting-related expenses of $1.8 million, partially offset by decreased convention-related expenses of $501,000 and decreased commissions expense of $158,000. The increase to media and advertising expenses are the result of our efforts to enhance customer acquisition, customer retention and global brand awareness. The increase to payroll and consulting-related expenses (i) is attributable to the increased headcount in our sales and marketing team both domestically and internationally, as we continued to expand into new and existing markets and (ii) includes an increase of $117,000 in stock-based compensation primarily attributable to grants to existing and new employees. The decrease in convention-related expenses is as a result of our period-over-period decrease in tradeshow attendance.

General and Administrative Expense. The decrease to general and administrative expense was primarily due to decreased legal expenses of $4.3 million and decreased provision for doubtful accounts of $482,000, partially offset by increased payroll and consulting-related expenses of $1.9 million. The decrease in legal expenses resulted from the atypical defense of the director dispute and resulting shareholder litigation incurred during the nine months ended September 30, 2015. The decrease in provision for doubtful accounts is due to our improvement in the collection process of receivables. The increase in payroll and consulting-related expenses resulted from a higher headcount in certain functions to support growth in our business, including an increase of $1.1 million in stock-based compensation primarily attributable to grants to directors and employees.

Engineering and Development Expense. The increase to engineering and development expense was primarily due to increased payroll, consulting and temporary labor expenses of $1.2 million and increased operating supplies cost of $702,000, resulting from our focused efforts to accelerate innovation of both our existing products and technologies as well as to develop new products and technologies, which we believe will further strengthen our worldwide leadership position. The increase in payroll, consulting and temporary labor expenses resulted from a higher headcount and includes an increase of $120,000 in stock-based compensation primarily attributable to grants to existing and new employees. Our engineering and development expenses fluctuate as our specific programs supporting product development transitions from one development phase to the next. Depending on the stage of completion and level of effort related to each development phase undertaken, we may reflect variations in our engineering and development expense. We expense engineering and development expenses as they are incurred.

Excise Tax Expense. The Patient Protection and Affordable Care Act imposes a 2.3% medical device excise tax on certain product sales to customers located in the U.S. We incurred excise tax expenses of $231,000, or 0.7% of net revenue, for the nine months ended September 30, 2015 as compared to $205,000, or 0.6% of net revenue, for the nine months ended September 30, 2014. The increase of $26,000, or 12.7%, in excise tax expense was primarily due to increased period-over-period laser systems revenue in the United States of approximately $989,000.

Legal Settlement. In April 2012, we filed a patent infringement lawsuit against Fotona Proizvodnja Optoelektronskih Naprav D.D. and Fotona LLC (collectively, “Fotona”) in Düsseldorf District Court alleging infringement with respect to the Fotona Fidelis dental laser system. On March 24, 2015, we entered into a settlement agreement with Fotona. We allocated $731,000 of the settlement amount toward the recovery of our legal expenses related to litigation. For a more detailed discussion of the intellectual property litigation, see Note 9 of the unaudited financial statements contained in this Form 10-Q.

(Loss) Gain on Foreign Currency Transactions. We realized a $97,000 loss on foreign currency transactions for the nine months ended September 30, 2015, compared to a $166,000 loss on foreign currency transactions for the nine months ended September 30, 2014 due to exchange rate fluctuations between the U.S. dollar and other currencies, primarily the Euro.

Interest Income (Expense), Net. Interest income during 2015 represents interest recognized from the discounted present value of the settlement in connection with the Fotona intellectual property litigation. Interest expense in 2015 consists of interest incurred on our capital lease obligations in connection with the lease of information technology equipment. Interest expense for 2014 consisted primarily of interest on our revolving credit facilities and amortization of debt issuance costs and debt discount. Interest income (expense), net totaled approximately $44,000 of income, or 0.1% of net revenue for the nine months ended September 30, 2015, as compared to an interest expense of $452,000 for the same prior year period. The decrease was primarily a result of the Company paying in full all amounts due under the revolving lines of credit with Comerica Bank in July 2014.

Income Tax Provision. Our provision for income taxes was $127,000 for the nine months ended September 30, 2015, compared to a provision of $81,000 for the nine months ended September 30, 2014. The increase of $46,000, or 56.8%, in income tax provision was primarily due to increased international sales revenue, which accounted for $14.0 million of net revenue in 2015 and $13.0 million of net revenue in 2014.

Net Loss. Our net loss for the nine months ended September 30, 2015 totaled approximately $17.8 million compared to a net loss of $14.8 million for the nine months ended September 30, 2014. The period-over-period increase in net loss of approximately $3.0 million, or 20.2%, was primarily due to a decrease in gross profit of $2.8 million and an increase in total operating expenses of $747,000, partially offset by a decrease in total non-operating net income of $565,000.

At September 30, 2015, we had approximately $15.4 million in cash and restricted cash equivalent. Management defines cash and cash equivalents as highly liquid deposits with original maturities of 90 days or less when purchased. The decrease in our cash and cash equivalents by $16.4 million at September 30, 2015 as compared to December 31, 2014, was primarily driven by cash used in operating activities of $15.0 million, cash used in investing activities of $1.2 million, cash used in financing activities of $22,000 and effect of exchange rate changes of $162,000.

The following table summarizes our change in cash and cash equivalents (in thousands):

Net cash used in operating activities consists of our net loss, adjusted for our non-cash charges, plus or minus working capital changes. Cash used in operating activities for the nine months ended September 30, 2015, totaled $15.0 million and was primarily comprised of our net loss of $17.8 million, partially offset by non-cash adjustments for stock-based compensation expense of $2.3 million, provision for bad debts of $207,000, provision for sales allowance of $100,000, deferred income taxes of $46,000, net interest income of $44,000 and depreciation and amortization expenses of $589,000. The $294,000 net decrease in our operating assets and liabilities was primarily due to a buildup of inventories of $1.6 million, an increase in accounts receivable of $500,000 related to the timing of our collections, an increase in restricted cash of $200,000 and an increase in prepaid expenses and other assets of $277,000 related to a legal settlement with a competitor during the first quarter of 2015, partially offset by an increase in accounts payable and accrued liabilities of $1.6 million related to the timing of our payments, a decrease in customer deposits of $7,000 and an increase in deferred revenue of $661,000 related to our Practice Growth Guaranteed program and a legal settlement with a competitor in the first quarter of 2015.

Cash used in investing activities for the nine months ended September 30, 2015 consisted primarily of $1.3 million of capital expenditures, partially offset by proceeds from disposal of property, plant, and equipment of $25,000. The period-over-period increase is primarily due to increased capital expenditures in 2015 for operating equipment and information technology equipment. For fiscal 2015, we expect capital expenditures to total approximately $2.0 million and we expect depreciation and amortization to total approximately $800,000.

Net cash used by financing activities for the nine months ended September 30, 2015 of $22,000 resulted from our deposit on capital lease of $42,000 and payments on our capital lease obligations of $24,000, partially offset by net proceeds received from stock options exercised of $44,000. In February 2014 and July 2014, we entered into two private placement transactions with investors providing net proceeds of approximately $4.8 million and $11.5 million, respectively. We did not enter into any private placements in 2015.

The $162,000 decrease in effect of exchange rate on cash was primarily due to a recognized $97,000 loss on foreign currency transactions due to a stronger U.S. dollar in 2015 than it was in 2014.

As of September 30, 2015, we had working capital of approximately $22.0 million. Our principal sources of liquidity at September 30, 2015 consisted of approximately $15.4 million in cash and restricted cash equivalent and $9.2 million of net accounts receivable.

In September 2015, we streamlined operations and reduced payroll, payroll-related and consulting-related expenses by approximately $2.4 million, net, on an annualized basis. Total expenses related to this restructuring during Third Quarter 2015 totaled approximately $246,000. We will begin to realize the impact of these cost saving measures in the fourth quarter of 2015 and throughout 2016.

In order for us to continue operations and be able to discharge our liabilities and commitments in the normal course of business, we must increase sales of our products directly to end-users and through distributors, establish profitable operations through the combination of increased sales and decreased expenses, and generate cash from operations or obtain additional funds when needed. We cannot guarantee that we will be able to increase sales, reduce expenses, or obtain additional funds if needed. If we are unable to increase sales, reduce expenses, or raise sufficient additional capital, we may be unable to continue to fund our operations, develop our products, or realize value from our assets and discharge our liabilities in the normal course of business.

Additional capital requirements may depend on many factors, including, among other things, the rate at which our business grows, demands for working capital, manufacturing capacity, and any acquisitions that we may pursue. From time to time, we could be required, or may otherwise attempt, to raise capital through either equity or debt offerings or by entering into a line of credit facility. We cannot provide assurance that we will enter into any such equity or debt financings in the future or that the required capital would be available on acceptable terms, if at all, or that any such financing activity would not be dilutive to our stockholders.
