Our Business-An Overview

NeuroMetrix, Inc., or the Company, a Delaware corporation, was founded in June 1996. The Company is a medical device company focused on the neurological complications of diabetes. The Company believes that its substantial experience in developing medical devices to stimulate and measure peripheral nerve function uniquely position it to address unmet medical needs related to diabetic neuropathy. Neuropathy is a common and serious, often painful, complication of diabetes that may lead to foot ulcers and limb amputation. The Company has over a decade of experience in neuropathy detection, starting with approval in 1998 by the United States Food and Drug Administration, or FDA, of the NC-stat System, a point-of-care device for the performance of general purpose nerve conduction studies.

In the first quarter of 2013, the Company completed product development and launched the SENSUS™ Pain Management System, or SENSUS, which is designed for relief of chronic, intractable pain. The Company believes this product will be attractive to pain medicine physicians, neurologists, endocrinologists, podiatrists, primary care physicians, and other physicians that are challenged with trying to manage pain in their patients with painful diabetic neuropathy, or PDN and other forms of neuropathic pain. The Company also markets the NC-stat^® DPNCheck^® device, which is a fast, accurate, and quantitative nerve conduction test that is used to evaluate systemic neuropathies such as diabetic peripheral neuropathy, or DPN. NC-stat DPNCheck is designed to be used by endocrinologists, podiatrists, primary care physicians and other clinicians at the point-of-care to objectively detect, stage, and monitor DPN. Sales efforts for NC-stat DPNCheck are currently targeted at opportunities in the managed care market. The Company’s historical neurodiagnostic business is based on the ADVANCE™ NCS/EMG System, or the ADVANCE System, which is a comprehensive platform for the performance of traditional nerve conduction studies and invasive electromyography procedures and which is primarily used in physician offices and clinics. While the ADVANCE System contributes the majority of the Company’s revenues, the Company is not actively managing the ADVANCE business for growth.

On June 4, 2013, the Company entered into a Securities Purchase Agreement, as amended (the “Purchase Agreement”), providing for the issuance of (i) 248,147 shares of common stock at a price of $2.095 per share, (ii) 1,066.254 shares of Series A-1 convertible preferred stock (the “Series A-1 Preferred Stock”) at a price of $1,000 per share, (iii) 3,370.510 shares of Series A-2 convertible preferred stock (the “Series A-2 Preferred Stock” and together with the Series A-1 Preferred Stock, the “Preferred Stock”) at a price of $1,000 per share, and (iv) five year warrants to purchase up to 2,365,934 shares of common stock with an exercise price of $2.00 per share (the “2013 Offering”). Each share of Preferred Stock is convertible into 477.327 shares of common stock, subject to adjustment, at any time at the option of the holder. The 2013 Offering resulted in approximately $5.0 million in gross proceeds, before deducting placement agent fees and other expenses. Net proceeds from the 2013 Offering were approximately $4.5 million. See Note 10, Stockholders’ Equity, for further details. As of September 30, 2013, 476.064 shares of Series A-1 Preferred Stock had been converted into 227,238 shares of common stock and 219.975 shares of Series A-2 Preferred Stock had been converted into 105,000 shares of common stock.

The Company held cash and cash equivalents of $7.8 million as of September 30, 2013. The Company believes that these resources and the cash to be generated from expected product sales will be sufficient to meet its projected operating requirements into the third quarter of 2014. The Company continues to face significant challenges and uncertainties and, as a result, the Company’s available capital resources may be consumed more rapidly than currently expected due to (a) decreases in sales of the Company’s products and the uncertainty of future revenues from new products; (b) changes the Company may make to the business that affect ongoing operating expenses; (c) changes the Company may make in its business strategy; (d) regulatory developments affecting the Company’s existing products and delays in the FDA approval process for products under development; (e) changes the Company may make in its research and development spending plans; and (f) other items affecting the Company’s forecasted level of expenditures and use of cash resources. Accordingly, the Company will need to raise additional funds to support its operating and capital needs in the third quarter of 2014 and beyond. The Company will attempt to obtain additional funding through public or private financing, collaborative arrangements with strategic partners, or through additional credit lines or other debt financing sources to increase the funds available to fund operations. However, the Company may not be able to secure such financing in a timely manner or on favorable terms, if at all. Furthermore, if the Company issues equity or debt securities to raise additional funds, its existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences and privileges senior to those of the Company’s existing stockholders. If the Company raises additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to its potential products or proprietary technologies, or grant licenses on terms that are not favorable to the Company. Without additional funds, the Company may be forced to delay, scale back or eliminate some of its sales and marketing efforts, research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue its operations. If any of these events occurs, the Company’s ability to achieve its development and commercialization goals would be adversely affected.

At September 30, 2013, one customer accounted for 10.6% of gross accounts receivable. No single customer has accounted for more than 10% of our revenues in the periods presented in this Form 10-Q.

Certain prior period amounts have been adjusted to reflect the Company's 1-for-6 reverse stock split of its common stock completed on February 15, 2013. See Note 11, Reverse Stock Split, for further details.

Unaudited Interim Financial Statements

The accompanying unaudited balance sheet as of September 30, 2013, unaudited statements of operations for the quarters and nine months ended September 30, 2013 and 2012 and the unaudited statements of cash flows for the nine months ended September 30, 2013 and 2012 have been prepared in accordance with accounting principles generally accepted in the United States of America for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by accounting principles generally accepted in the United States of America for complete financial statements. In the opinion of management, the financial statements include all normal and recurring adjustments considered necessary for a fair statement of the Company’s financial position and operating results. Operating results for the quarter and nine months ended September 30, 2013 are not necessarily indicative of the results that may be expected for the year ending December 31, 2013 or any other period. These financial statements and notes should be read in conjunction with the financial statements for the year ended December 31, 2012 included in the Company’s Annual Report on Form 10-K, as filed with the Securities and Exchange Commission, or the SEC, on February 25, 2013 (File No. 001-33351), or the Company’s 2012 Form 10-K. The accompanying balance sheet as of December 31, 2012 has been derived from audited financial statements prepared at that date, but does not include all disclosures required by accounting principles generally accepted in the United States of America.

Revenues

The Company recognizes revenue when the following criteria have been met: persuasive evidence of an arrangement exists, delivery has occurred and risk of loss has passed, the seller’s price to the buyer is fixed or determinable, and collection is reasonably assured.

Revenues associated with the sale of the ADVANCE devices to customers and distributors are recognized upon shipment, provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, product returns are reasonably estimable, and no continuing obligations exist. The revenues from the sale of an ADVANCE communication hub together with access to NeuroMetrix information systems are considered one unit of accounting and deferred and recognized on a straight-line basis over the estimated period of time that the Company provides the service associated with the information systems of three years. The resulting deferred revenue and deferred costs are presented as separate line items on the accompanying balance sheet. Revenues related to extended service agreements for the devices are recognized ratably over the term of the extended service agreement.

Revenues associated with the sale of the SENSUS and NC-stat DPNCheck devices are recognized upon shipment, provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, product returns are reasonably estimable, and no continuing obligations exist.

Revenues also include sales of consumables, including single use nerve specific electrodes and other accessories. These revenues are recognized upon shipment provided that the selling price is fixed or determinable, persuasive evidence of an arrangement exists, collection of receivables is reasonably assured, and product returns are reasonably estimable.

When multiple elements are contained in a single arrangement, the Company allocates revenue between the elements based on their relative selling prices. The Company determines selling price using vendor specific objective evidence, or VSOE, if it is available, third-party evidence, or TPE, if VSOE is not available, and best estimate of selling price, or BESP, if neither VSOE nor TPE are available. The Company generally expects that it will not be able to establish TPE due to the nature of the markets in which it competes, and, as such, it will typically determine selling price using VSOE or if not available, BESP. The objective of BESP is to determine the selling price of a deliverable on a standalone basis. The Company’s determination of BESP involves a weighting of several factors based on the specific facts and circumstances of an arrangement. Specifically, the Company considers the cost to produce the deliverable, the anticipated margin on that deliverable, the selling price and profit margin for similar parts, its ongoing pricing strategy, the value of any enhancements that have been built into the deliverable, and the characteristics of the varying markets in which the deliverable is sold.

Revenue recognition involves judgments, including assessments of expected returns and expected customer relationship periods. The Company analyzes various factors, including a review of specific transactions, its historical returns, average customer relationship periods, customer usage, customer balances, and market and economic conditions. Changes in judgments or estimates on these factors could materially impact the timing and amount of revenues and costs recognized. Should market or economic conditions deteriorate, the Company’s actual return or bad debt experience could exceed its estimate.

Certain product sales are made with a 30-day right of return. Since the Company can reasonably estimate future returns, it recognizes revenues associated with product sales that contain a right of return upon shipment and at the same time it records a sales return reserve, which reduces revenue and accounts receivable by the amount of estimated returns.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make significant estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenue and expenses during reporting periods. Actual results could differ from those estimates.

Recent Accounting Pronouncements

There have been no recent accounting pronouncements or changes in accounting pronouncements since the recent accounting pronouncements described in the Company's 2012 Form 10-K that are of significance to the Company.

For the quarters and nine months ended September 30, 2013 and 2012, the Company had no components of other comprehensive income or loss other than net loss itself.

Basic net loss per common share is computed by dividing net loss applicable to common stockholders by the weighted average number of common shares outstanding during the period. Unvested restricted shares, although legally issued and outstanding, are not considered outstanding for purposes of calculating basic net income per share. Diluted net loss per common share is computed by dividing net loss by the weighted average number of common shares outstanding during the period plus the dilutive effect of the weighted average number of outstanding instruments such as options, warrants, restricted stock, and preferred stock. Because the Company has reported a net loss for all periods presented, diluted loss per common share is the same as basic loss per common share, as the effect of utilizing the fully diluted share count would have reduced the net loss per common share. Therefore, in calculating net loss per share amounts, shares underlying the following potentially dilutive weighted average number of common stock equivalents were excluded from the calculation of diluted net income per common share because their effect was anti-dilutive for each of the periods presented:

The Beneficial Conversion Feature, or BCF, recorded in the 2013 Offering has been recognized as a deemed dividend attributable to the Preferred Stock and is reflected as an adjustment in the calculation of earnings per share. See Note 10, Stockholders’ Equity, for further details.

Net loss per common share applicable to common stockholders, basic and diluted was determined as follows:

On June 4, 2013, the Company entered into a Securities Purchase Agreement, pursuant to which it issued (i) 248,147 shares of common stock at a price of $2.095 per share, (ii) 1,066.254 shares of Series A-1 Preferred Stock at a price of $1,000 per share, (iii) 3,370.510 shares of Series A-2 Preferred Stock at a price of $1,000 per share, and (iv) five year warrants to purchase up to 2,365,934 shares of common stock with an exercise price of $2.00 per share. Additionally, during the quarter ended September 30, 2013, 476.064 shares of Series A-1 Preferred Stock had been converted into 227,238 shares of common stock and 219.975 shares of Series A-2 Preferred Stock had been converted into 105,000 shares of common stock. See Note 10, Stockholders’ Equity, for further details.

In March 2013, the Company awarded certain executives an aggregate of 119,370 shares of fully vested common stock with a value of $285,300 in settlement of 2012 incentive compensation obligations. The value of the shares issued reflected the $2.39 closing price of the Company’s common stock as reported on the NASDAQ Capital Market on March 4, 2013.

In March 2012, the Company issued 23,127 shares of its common stock in satisfaction of the Company’s obligation to redeem certain warrants issued by the Company pursuant to Securities Purchase Agreements dated as of September 8, 2009. No cash was paid to redeem the warrants.

On February 13, 2012, the Company completed a public offering of 1,421,735 Units at a price of $6.00 per Unit (the “2012 Offering”). Each Unit consisted of one share of the Company’s common stock and one warrant to purchase one half of a share of the Company’s common stock. The Company issued 1,421,735 shares of common stock and warrants to purchase 781,955 shares of common stock and received proceeds, net of discounts, commissions and expenses, of approximately $7.4 million. See Note 10, Stockholders’ Equity, for further details.

Inventories consist of the following:

Accrued compensation includes $290,305 of unpaid severance incurred in the second and third quarters of 2013. The following table provides a rollforward of the liability balance for severance, of which $382,900 and $136,900 was recorded as sales and marketing expense and research and development expense, respectively, in the Company’s Statement of Operations during the 9 months ended September 30, 2013. The balance as of September 30, 2013 will be paid out by March 31, 2014. There were no severance charges or payments in the nine months ended September 30, 2012. There were no severance charges accrued as of December 31, 2012.

Accrued expenses consist of the following:

Operating Leases

The Company leases office and engineering laboratory space in Waltham, Massachusetts. In June 2013, the lease term was extended through March 31, 2015. Base rent for the period October 2013 through March 2015 is $52,917 per month.

In July 2013, the Company entered into a non-cancelable operating lease for copiers located at its corporate headquarters, expiring in July 2016. Base rent for the period October 2013 through July 2016 is $1,728 per month.  

The Fair Value Measurements and Disclosures topic of the Financial Accounting Standards Board, Accounting Standards Codification (the “Codification”) defines fair value, establishes a framework for measuring fair value in applying generally accepted accounting principles, and expands disclosures about fair value measurements. This Codification topic identifies two kinds of inputs that are used to determine the fair value of assets and liabilities: observable and unobservable. Observable inputs are based on market data or independent sources while unobservable inputs are based on the Company’s own market assumptions. Once inputs have been characterized, this Codification topic requires companies to prioritize the inputs used to measure fair value into one of three broad levels. Fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values identified by Level 2 inputs utilize observable inputs other than Level 1 prices, 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 related assets or liabilities. Fair values identified by Level 3 inputs are unobservable data points and are used to measure fair value to the extent that observable inputs are not available. Unobservable inputs reflect the Company’s own assumptions about the assumptions that market participants would use at pricing the asset or liability.

The following tables present information about the Company’s assets and liabilities that are measured at fair value on a recurring basis for the periods presented and indicates the fair value hierarchy of the valuation techniques it utilized to determine such fair value. In general, fair values determined by Level 1 inputs utilize quoted prices (unadjusted) in active markets for identical assets or liabilities. Fair values determined by Level 2 inputs utilize data points that are observable such as quoted prices, interest rates, and yield curves. Fair values determined by Level 3 inputs are unobservable data points for the asset or liability, and include situations where there is little, if any, market activity for the asset or liability.

Due to the lack of market quotes relating to our common stock warrants, the fair value of the common stock warrants was determined at September 30, 2013 using the Black-Scholes model, which is based on Level 3 inputs. As of September 30, 2013, inputs used in the Black-Scholes model include our stock price as of that date of $1.65, exercise price of $2.00, expected volatility of 67.58%, risk free interest rate of 1.40%, expected term of approximately four years and 8 months, and no dividends. The assumptions used may change as the underlying sources of these assumptions and market conditions change. Based on this calculation, the Company recorded other non-operating income of $0.9 million during the quarter ended September 30, 2013, resulting in a common stock warrants liability of $2.0 million at September 30, 2013. The Company did not have any financial liabilities carried at fair value as of December 31, 2012.

The following table provides a summary of changes in the fair value of the Company's Level 3 financial liabilities for the three and nine month periods ended September 30, 2013:

The Company is party to a Loan and Security Agreement, or the Credit Facility, with a bank. As of September 30, 2013, the Credit Facility permitted the Company to borrow up to $2.5 million on a revolving basis. The amended Credit Facility expires on January 31, 2014. Amounts borrowed under the Credit Facility will bear interest equal to the prime rate plus 0.5%. Any borrowings under the Credit Facility will be collateralized by the Company’s cash, accounts receivable, inventory, and equipment. The Credit Facility includes traditional lending and reporting covenants. These include certain financial covenants applicable to liquidity that are to be maintained by the Company. As of September 30, 2013 and December 31, 2012, the Company was in compliance with these covenants and had not borrowed any funds under the Credit Facility. Of the Credit Facility limit, $225,000 is restricted to support a letter of credit issued in favor of the Company’s landlord in the lease of its facilities in Waltham, Massachusetts. Consequently, the amount available for borrowing under the Credit Facility as of September 30, 2013 was $2,275,000.

On June 4, 2013, the Company entered into a Purchase Agreement providing for the issuance of (i) 248,147 shares of common stock at a price of $2.095 per share, (ii) 1,066.254 shares of Series A-1 Preferred Stock at a price of $1,000 per share, (iii) 3,370.510 shares of Series A-2 Preferred Stock at a price of $1,000 per share, and (iv) five year warrants to purchase up to 2,365,934 shares of common stock with an exercise price of $2.00 per share. The 2013 Offering resulted in approximately $5.0 million in gross proceeds, before deducting placement agent fees and other expenses. Net proceeds from the 2013 Offering were approximately $4.5 million.

The shares of Preferred Stock have a stated value of $1,000 and are convertible at the option of the holder into the number of shares of common stock determined by dividing the stated value by the initial conversion price of $2.095, which is subject to adjustment as provided in each Certificate of Designation for the Preferred Stock. The Preferred Stock has no dividend rights, liquidation preference or other preferences over common stock and has no voting rights except as provided in each Certificate of Designation for the Preferred Stock and as required by law. The warrants to purchase 2,365,934 shares of common stock were exercisable immediately, have a five-year term, and a per share exercise price of $2.00.

The terms and conditions of the Preferred Stock were evaluated based on the guidance of the Derivatives and Hedging topic of the Codification to determine if the conversion feature was an embedded derivative requiring bifurcation. It was concluded that bifurcation was not required because the conversion feature was clearly and closely related to the Preferred Stock. The conversion price at which shares of Preferred Stock are convertible into shares of common stock was determined to be lower than the fair value of common stock at the date of the Purchase Agreement. This “in-the-money” beneficial conversion feature, or BCF, required separate recognition and measurement of its intrinsic value (i.e., the amount of the increase in value that holders of Preferred Stock would realize upon conversion based on the value of the conversion shares on the date of the Purchase Agreement). The BCF measurement totaled $766,900, an amount limited by the transaction proceeds which had been allocated to the Preferred Stock. Because there is not a stated redemption date for the shares of Preferred Stock, the BCF was recognized as a deemed dividend attributable to the Preferred Stock and is reflected as an adjustment in the calculation of earnings per share.

The warrants issued in connection with the 2013 Offering are within the scope of the Derivatives and Hedging topic of the Codification. This Codification topic requires issuers to classify as liabilities (or assets under certain circumstances) financial instruments which require an issuer to settle in registered shares. As the warrants are required to be settled in registered shares when exercised, the Company has reflected the warrants as a liability in the balance sheet. The fair value of the warrants at the date of the 2013 Offering was estimated at $4.0 million using a Black-Scholes model with the following assumptions: stock price of $2.60, exercise price of $2.00, expected volatility of 73.6%, risk free interest rate of 1.05%, expected term of five years, and no dividends. The warrants were revalued at June 30, 2013 and September 30, 2013 using the same Black-Scholes model. The warrants liability was reflected in the balance sheet at September 30, 2013 in the amount of $2.0 million, resulting in the recognition of non-operating income of $2.0 million through September 30, 2013. The Company will continue to revalue unexercised warrants at each reporting period over the life of the warrants using the Black-Scholes model and the changes in the fair value of the warrants will be recognized in the Company's statement of operations.

On July 8, 2013, 266.564 shares of Series A-1 Preferred Stock were converted into 127,238 shares of the Company’s common stock and 10.475 shares of Series A-2 Preferred Stock were converted into 5,000 shares of the Company’s common stock. On August 5, 2013, 209.5 shares of Series A-1 Preferred Stock were converted into 100,000 shares of the Company’s common stock and 209.5 shares of Series A-2 Preferred Stock were converted into 100,000 shares of the Company’s common stock. On October 2, 2013, 209.5 shares of Series A-1 Preferred Stock were converted into 100,000 shares of the Company’s common stock and on October 3, 2013, 104.75 shares of Series A-2 Preferred Stock were converted into 50,000 shares of the Company’s common stock.

On July 26, 2013, the Company filed a Registration Statement on Form S-8 to register 386,111 additional shares of the Company’s common stock for issuance under the Company’s 2009 Non-Qualified Inducement Stock Plan (the “2009 Stock Plan”). An aggregate of 13,889 shares of common stock to be issued under the 2009 Stock Plan were previously registered on June 3, 2009. The amount previously registered reflects two 1-for-6 reverse splits of the Company’s common stock completed on September 1, 2011 and February 15, 2013.

On February 13, 2012, the Company completed the 2012 Offering, which included 1,421,735 Units at a price of $6.00 per Unit. Each Unit consisted of one share of the Company’s common stock and one warrant to purchase one half of a share of the Company’s common stock. The Company issued 1,421,735 shares of common stock and warrants to purchase 710,868 shares of common stock and received proceeds, net of discounts, commissions and expenses, of approximately $7.4 million. Each warrant entitles the holder to purchase at any time during the period commencing 180 days after the date of the 2012 Offering until the date five years following the closing date of the 2012 Offering, one half of a share of the Company’s common stock. Two warrants would need to be exercised to acquire one share of the Company’s common stock at an exercise price of $6.90 (115% of the aggregate price of the 2012 Offering for a Unit). In addition, the placement agent for the 2012 Offering was issued warrants to purchase 71,087 shares of common stock (equal to 5.0% of the number of shares of common stock included in the Units sold in the 2012 Offering) at an exercise price of $7.50 per share (125% of the aggregate price for a Unit). The placement agent’s warrants became exercisable one year after the date of issuance and will expire on the fifth anniversary of the effectiveness of the registration statement related to the 2012 Offering.

The fair value of the warrants issued in the 2012 Offering was estimated at $2.4 million using a Black-Scholes model with the following assumptions: expected volatility of 73.5%, risk free interest rate of 0.85%, expected term of five years, and no dividends. The volatility assumption is based on weekly historical volatility during the time period that corresponds to the expected option term, a review of comparable medical device companies, and expected future stock price volatility. The relative fair value of the warrants was recorded as equity.

On February 15, 2013, the Company filed a Certificate of Amendment to its Restated Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware, to effect a 1-for-6 reverse stock split of its common stock. This action had previously been approved by the Company’s stockholders at a special meeting of stockholders held on December 7, 2012 and was intended to address the Company’s deficiency in compliance with the minimum bid listing requirements of the NASDAQ Stock Market. As a result of the reverse stock split, every six shares of the Company’s pre-reverse split common stock were combined and reclassified into one share of its common stock. No fractional shares were issued in connection with the reverse stock split. Stockholders who otherwise would have been entitled to receive a fractional share in connection with the reverse stock split received a cash payment in lieu thereof. The par value and other terms of the common stock were not affected by the reverse stock split.

The Company’s shares outstanding immediately prior to the reverse stock split totaled 12,845,228. These were adjusted to 2,140,871 shares outstanding as a result of the reverse stock split. The Company’s common stock began trading at its post-reverse stock split price at the beginning of trading on February 19, 2013. Share, per share, and stock option amounts for all periods presented within this quarterly report on Form 10-Q and the amounts for common stock and additional paid-in capital have been retroactively adjusted to reflect the reverse stock split.

On March 5, 2013, the Company received a letter from The NASDAQ Stock Market indicating that it had regained compliance with the minimum bid price requirement under NASDAQ Listing Rule 5550(a)(2) for continued listing on The NASDAQ Capital Market. The Company’s common stock continues to be listed on The NASDAQ Capital Market.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations

Overview

We are a medical device company focused on the neurological complications of diabetes. People with diabetes do not effectively regulate their blood glucose, or sugar, levels leading to chronically high levels of glucose in the blood, called hyperglycemia, and occasionally bouts of low glucose in the blood, called hypoglycemia. The primary reason that glucose levels are not effectively regulated in people with diabetes is that those with the disease do not produce insulin (Type I diabetes) or are resistant to the normal physiological action of insulin (Type II diabetes). Many Type II diabetics eventually require insulin because production of the hormone by their pancreas decreases with time. Type I diabetes usually affects children and teenagers whereas Type II diabetes has typically been a disease of adults over the age of 50. However, over the past decade, Type II diabetes is occurring in younger adults, which can probably be attributed to higher levels of obesity in this age group.

We believe that there are large and important unmet needs in the treatment of diabetic neuropathies. As a medical device company with both unique and substantial experience in devices to measure and alter peripheral nerve function, we believe we are in the unique position to address these unmet needs through the development of novel proprietary medical devices. Therefore, we are focused on developing and marketing medical devices for the diagnosis and treatment of diabetic neuropathies. We believe that we are the only medical device company with a strategic focus on the diabetic neuropathy market and our goal is to be the dominant player in this field.

Since we shifted our strategic focus to the diabetic neuropathy market in 2011, we have launched two products with the potential to change medical practice. SENSUS, our therapeutic device for relief of chronic, intractable pain, was launched in January 2013. SENSUS is a convenient and wearable non-invasive device that offers physicians and their patients a non-narcotic pain relief option as a complement to medications. The device is lightweight and can be worn during the day while remaining active, or at night while sleeping. The Company believes it is the only transcutaneous electrical nerve stimulator designed specifically for people with diabetes that suffer from chronic pain. We believe this product will be attractive to pain medicine physicians, neurologists, endocrinologists, podiatrists, primary care physicians, and other physicians that are challenged with trying to manage pain in their patients with painful diabetic neuropathy, or PDN and other forms of neuropathic pain. The prevalence of PDN indicates a patient group of 3 - 5 million in the United States alone. In the U.S., SENSUS is a prescription product and our initial challenge will be to obtain broad, national exposure and acceptance among physicians as well as a broad distribution channel to fulfill prescriptions. We are working to create demand in several distinct channels: independent regional and national durable medical equipment, or DME, suppliers that employ sales representatives who detail physicians, large direct sale customers such as orthotic and prosthetic clinics and chronic pain treatment centers, and national diabetes mail order DME’s. We believe there may be future opportunities to expand the SENSUS revenue and gross margin potential by developing a direct sales channel.

NC-stat DPNCheck, our diagnostic test for diabetic peripheral neuropathy, or DPN, has been on the market since launch in late 2011. Revenues were nearly $1.5 million in 2012 and were $761,000 and $1.1 million for the nine months ended September 30, 2013 and 2012, respectively. Our sales efforts in the U.S. market are focused on Medicare Advantage providers. Medicare Advantage providers assume financial responsibility and the associated risks for the health care costs of their patients. For Medicare Advantage providers, we believe that NC-stat DPNCheck presents an attractive clinical case with early detection of neuropathy allowing for earlier clinical intervention to help mitigate the effects of neuropathy on both patient quality of life and cost of care. Also, the diagnosis and documentation of neuropathy provided by NC-stat DPNCheck helps clarify the patient health profile which, in turn, may have a direct, positive effect on the Medicare Advantage premium received by the provider. Changes to the Medicare Advantage patient assessment and premium structure effective for 2014 have narrowed the financial benefits from early diagnosis of DPN. This has reduced the market opportunity and delayed adoption of NC-stat DPNCheck. Accordingly, our sales efforts now encompass corporate-based sales outreach in addition to support to our existing customers. Attractive international market opportunities are developing in Japan, South Korea and Europe. These are led by our local distributors with support from our corporate office.

We are currently involved in seven studies that use NC-stat DPNCheck in the evaluation of neuropathy in persons with diabetes under various study conditions. We anticipate that these studies will expand the clinical foundation for use of NC-stat DPNCheck which, in turn, should support future adoption by customers. We are also developing plans for clinical studies employing SENSUS.

We continue to manage our historical neurodiagnostics business which is centered on the ADVANCE System. This business generated $6.1 million in revenue during 2012 and $3.0 million and $5.0 million for the nine months ended September 30, 2013 and 2012, respectively. There are few direct cash operating expenses of the business. The neurodiagnostic business has been in decline for several years due to reimbursement challenges. We envision this line of our business will continue to decline as we operate it for cash flow.

On June 4, 2013, we entered into a Securities Purchase Agreement, as amended, or the Purchase Agreement, providing for the issuance of (i) 248,147 shares of common stock at a price of $2.095 per share, (ii) 1,066.254 shares of Series A-1 convertible preferred stock, or the “Series A-1 Preferred Stock”, at a price of $1,000 per share, (iii) 3,370.510 shares of Series A-2 convertible preferred stock, or the Series A-2 Preferred Stock, at a price of $1,000 per share, and (iv) five year warrants to purchase up to 2,365,934 shares of common stock with an exercise price of $2.00 per share, which we collectively refer to as the 2013 Offering. The 2013 Offering resulted in approximately $5.0 million in gross proceeds, before deducting placement agent fees and other expenses. Net proceeds from the 2013 Offering were approximately $4.5 million. As of October 3, 2013, 685.564 shares of Series A-1 Preferred Stock had been converted into 327,238 shares of common stock and 324.725 shares of Series A-2 Preferred Stock had been converted into 155,000 shares of common stock.

Results of Operations

Comparison of Quarters Ended September 30, 2013 and 2012

Revenues

The following table summarizes our revenues:

Revenues include sales from SENSUS, our therapeutic device for relief of chronic, intractable pain launched in January 2013; NC-stat DPNCheck, our diagnostic test for DPN; and our legacy ADVANCE neurodiagnostics business. During the third quarter of 2013, we shipped 557 SENSUS devices and recorded revenue of $73,000. This is the early launch period for the product as we work to develop national distribution in several sales channels, including DME suppliers addressing pain physicians, primary care physicians and endocrinologists, large clinic organizations and direct mail diabetes suppliers. We also recorded NC-stat DPNCheck revenue of $317,000, compared to $306,000 in the third quarter of 2012. ADVANCE revenues totaled $925,000 in comparison with $1.5 million in the third quarter of 2012. The decline in ADVANCE revenue continues the historical trend for this product line which is managed for cash flow.

Cost of Revenues and Gross Profit

The following table summarizes our cost of revenues and gross profit:

Reflecting our decrease in revenues, our cost of revenues decreased to $578,500 in the third quarter of 2013, compared to $794,000 in the third quarter of 2012. However, our gross margin increased to 56.0% in the third quarter of 2013 from 55.0% in the third quarter of 2012. Our 2013 gross margin improvement was primarily attributable to improved pricing on NC-stat DPNCheck consumable biosensors.

Operating Expenses

The following table presents a breakdown of our operating expenses:

Research and Development

Research and development expenses for the quarters ended September 30, 2013 and 2012 were $740,300 and $980,300, respectively. The comparative results largely reflect a $161,600 decrease in personnel costs, resulting from lower headcount and incentive compensation expense, and an $118,400 decrease in the cost of clinical studies and development, partially offset by a $29,600 increase in recruiting costs for a new software engineer.

Sales and Marketing

Sales and marketing expenses decreased to $581,100 for the quarter ended September 30, 2013 from $1.5 million for the quarter ended September 30, 2012. During 2012, we reduced our dependence on field clinical educators to support our neurodiagnostic business and we shifted our NC-stat DPNCheck emphasis toward managed care, allowing us to eliminate our endocrinology/podiatry direct sales representatives. In addition, during 2013 we further reduced our sales staff, largely in support of NC-stat DPNCheck, resulting in severance cost of $90,700 in the third quarter of 2013. As a result, total sales and marketing personnel costs, including compensation and benefits, which includes the $90,700 of incremental severance costs in 2013, were $492,000 lower than in the quarter ended September 30, 2012. Further, travel costs decreased $140,300, trade show costs decreased $57,400, and advertising and promotion costs decreased $36,700. In addition, sales and marketing expenses for 2012 included $57,900 for a write-off on loaner and demonstration systems.

General and Administrative

General and administrative expenses decreased to $1.0 million for the quarter ended September 30, 2013 compared to $1.1 million for the same quarter in 2012. This decrease included $105,500 for consultants and temporary staff, $37,000 for travel costs, $29,600 for personnel costs, and $23,900 for taxes. This was partially offset by adjustments to accounts receivable credit balances of $47,100 recorded in the quarter ended September 30, 2012.

Interest Income

Interest income was approximately $1,400 and $3,500 for the quarters ended September 30, 2013 and 2012, respectively. Interest income was earned from investments in cash equivalents.

Change in fair value of warrant liability

The change in fair value of warrant liability of $881,800 relates to the revaluation of warrants from the fair value of $2.9 million estimated at June 30, 2013 to $2.0 million at September 30, 2013. The Black-Scholes model is utilized in calculating the fair value of the warrant liability. The lower fair value at September 30, 2013 reflects our lower stock price at September 30, 2013 compared to June 30, 2013, as well as the shorter remaining term of the warrants.

Comparison of Nine Months Ended September 30, 2013 and 2012

Revenues

The following table summarizes our revenues:

Revenues include sales from SENSUS, our therapeutic device for relief of chronic, intractable pain launched in January 2013; NC-stat DPNCheck, our diagnostic test for DPN; and our legacy ADVANCE neurodiagnostics business. During the nine months ended September 30, 2013, we shipped 910 SENSUS devices and recorded revenue of $138,000. This is the early launch period for the product as we work to develop national distribution in several sales channels, including DME suppliers addressing pain physicians, primary care physicians and endocrinologists, large clinic organizations and direct mail diabetes suppliers. We also recorded NC-stat DPNCheck revenue of $761,000, down from $1.1 million for the nine months ended September 30, 2012. The 2012 activity included large, initial NC-stat DPNCheck stocking orders from two new customers which accounted for the majority of this variance. ADVANCE revenues totaled $3.0 million in comparison with $5.0 million for the nine months ended September 30, 2012. The decline in ADVANCE revenue continues the historical trend for this product line which is managed for cash flow.

Cost of Revenues and Gross Profit

The following table summarizes our cost of revenues and gross profit:

Corresponding with our decrease in revenues, our cost of revenues decreased to $1.6 million for the first nine months of 2013, compared to $2.9 million for the first nine months of 2012. However, our gross margin increased to 57.5% in the first nine months of 2013 from 51.9% in the first nine months of 2012. Our 2013 gross margin improvement was primarily attributable to improved pricing on NC-stat DPNCheck consumable biosensors. In addition, for the first nine months of 2012, gross margin was depressed by 3.6% due to a net non cash charge, largely related to excess inventory, of $197,900 resulting from our decision to consolidate our neurodiagnostics installed customer base on a single technology platform, the ADVANCE System.

Operating Expenses

The following table presents a breakdown of our operating expenses:

Research and Development

Research and development expenses for the nine months ended September 30, 2013 and 2012 were $2.7 million and $3.0 million, respectively. The comparative results largely reflect a $310,400 decrease in personnel costs, resulting from lower headcount and incentive compensation expense, partially offset by a $29,600 increase in recruiting costs for a new software engineer. Personnel costs for 2013 include $136,900 for severance incurred in the second quarter of 2013.

Sales and Marketing

Sales and marketing expenses decreased to $2.2 million for the nine months ended September 30, 2013 from $4.6 million for the nine months ended September 30, 2012. During 2012, we reduced our dependence on field clinical educators to support our neurodiagnostic business and we shifted our NC-stat DPNCheck emphasis toward managed care, allowing us to eliminate our endocrinology/podiatry direct sales representatives. In addition, in 2013 we have further reduced our sales staff, largely in support of NC-stat DPNCheck, resulting in severance cost of $382,900 for the nine months ended September 30, 2013. As a result, total sales and marketing personnel costs, including compensation and benefits, which includes the $382,900 of incremental severance costs in 2013, were $1.4 million lower than in the nine months ended September 30, 2012. In addition, travel costs decreased $404,900, trade show costs decreased $81,300, advertising and promotion costs decreased $64,000, consulting and outside services costs decreased $58,100, dues decreased $45,400, and depreciation decreased $38,500. Sales and marketing expenses for 2012 included $57,900 for a write-off on loaner and demo systems.

General and Administrative

General and administrative expenses decreased to $3.2 million for the nine months ended September 30, 2013 compared to $3.7 million for the same period in 2012. This decrease included $238,200 for consultants and temporary staff, $97,500 for personnel costs, $77,100 for professional fees, $74,400 for taxes and fees, $71,300 for travel costs, $58,500 for insurance and outside administration, and $46,800 for stock-based compensation. These decreases were partially offset by an increase in bad debt expense of $235,500.

Interest Income

Interest income was approximately $4,600 and $11,800 for the nine months ended September 30, 2013 and 2012, respectively. Interest income was earned from investments in cash equivalents.

Warrants offering costs

Warrants offering costs of $376,300 consists of offering costs allocated to warrants in the 2013 Offering.

Change in fair value of warrant liability

The change in fair value of warrant liability of $2.0 million relates to the revaluation of warrants from the fair value of $4.0 million estimated as of the closing date of the 2013 Offering to $2.0 million at September 30, 2013. The Black-Scholes model is utilized in calculating the fair value of the warrant liability. The lower fair value at September 30, 2013 reflects our lower stock price at September 30, 2013 compared to June 4, 2013, as well as the shorter remaining term of the warrants.

Liquidity and Capital Resources

Our principal source of liquidity is our cash and cash equivalents. As of September 30, 2013, cash and cash equivalents totaled $7.8 million. On June 4, 2013, we entered into a Purchase Agreement providing for the issuance of (i) 248,147 shares of common stock at a price of $2.095 per share, (ii) 1,066.254 shares of Series A-1 Preferred Stock at a price of $1,000 per share, (iii) 3,370.510 shares of Series A-2 Preferred Stock at a price of $1,000 per share, and (iv) five year warrants to purchase up to 2,365,934 shares of common stock with an exercise price of $2.00 per share, which we collectively refer to as the 2013 Offering. The 2013 Offering resulted in approximately $4.5 million net proceeds, after deducting placement agent fees and other expenses. See Note 10, Stockholders’ Equity, of our Notes to Unaudited Financial Statements contained elsewhere in this Quarterly Report on Form 10-Q for further information regarding this transaction. Our ability to generate revenue to generate funds to operate our business will largely depend on the success of our diabetes business initiative and our ability to manage our legacy neurodiagnostics business to optimize cash flow. A low level of market interest in NC-stat DPNCheck or SENSUS, an accelerated decline in our neurodiagnostics consumables sales, or unanticipated increases in our operating costs would have an adverse effect on our liquidity and cash generated from operations.

The following table sets forth information relating to our cash and cash equivalents:

In order to supplement our access to capital, we are party to an amended Loan and Security Agreement, with a bank which provides us with a credit facility in the amount of $2.5 million. The amended credit facility expires on January 31, 2014. Amounts borrowed under the credit facility will bear interest equal to the prime rate plus 0.5%. Any borrowings under the credit facility will be collateralized by our cash, accounts receivable, inventory, and equipment. The credit facility includes traditional lending and reporting covenants. These include certain financial covenants applicable to liquidity that are to be maintained by us. As of September 30, 2013, we were in compliance with these covenants and had not borrowed any funds under the credit facility. Of the credit facility limit, $225,000 is restricted to support a letter of credit issued in favor of our landlord in connection with the lease of our facilities in Waltham, Massachusetts. Consequently, the amount available for borrowing under the credit facility as of September 30, 2013 was $2,275,000.

During the first nine months of 2013, our cash and cash equivalents decreased by $863,300 due mainly to net cash used in operating activities of $5.3 million, partially offset by net proceeds of $4.5 million from the 2013 Offering.

In managing our working capital, two of the financial measurements we monitor are days sales outstanding, or DSO, and inventory turnover rate, which are presented in the table below for the quarters ended September 30, 2013 and 2012, and the year ended December 31, 2012:

Payment terms extended to our customers generally require payment within 30 days from invoice date. DSO’s have increased since December 31, 2012 due to the decline in revenues and slower collections. The inventory turnover rate has increased since December 31, 2012 due to decreased inventory.

The following table sets forth information relating to the sources and uses of our cash:

Our operating activities used $5.3 million in the nine months ended September 30, 2013. The primary driver for the use of cash in our operating activities during the first nine months of 2013 was our net loss of $4.3 million, which included a non-cash credit of $2.0 million for the change in fair value of the warrant liability and non-cash charges of $376,300 for offering costs allocated to warrants in the 2013 Offering, $158,900 for stock-based compensation, $116,400 for depreciation and amortization, and $95,200 for inventory charges.

Financing activities for the nine months ended September 30, 2013 included $4.5 million from the net proceeds from the 2013 Offering. Financing activities for the nine months ended September 30, 2012 included $7.5 million from the net proceeds from the 2012 Offering.

We held cash and cash equivalents of $7.8 million as of September 30, 2013. We believe that these resources and the cash to be generated from expected product sales will be sufficient to meet our projected operating requirements into the third quarter of 2014. We continue to face significant challenges and uncertainties and, as a result, our available capital resources may be consumed more rapidly than currently expected due to (a) decreases in sales of our products and the uncertainty of future revenues from new products; (b) changes we may make to the business that affect ongoing operating expenses; (c) changes we may make in our business strategy; (d) regulatory developments affecting our existing products and delays in the FDA approval process for products under development; (e) changes we may make in our research and development spending plans; and (f) other items affecting our forecasted level of expenditures and use of cash resources. Accordingly, we will need to raise additional funds to support our operating and capital needs in the third quarter of 2014 and beyond. We will attempt to obtain additional funding through public or private financing, collaborative arrangements with strategic partners, or through additional credit lines or other debt financing sources to increase the funds available to fund operations. However, we may not be able to secure such financing in a timely manner or on favorable terms, if at all. We maintain a shelf registration statement on Form S-3 with the SEC covering shares of our common stock and other securities for sale, giving us the opportunity to raise funding when needed or otherwise considered appropriate at prices and on terms to be determined at the time of any such offerings. However, pursuant to the instructions to Form S-3, we only have the ability to sell shares under the shelf registration statement, during any 12-month period, in an amount less than or equal to one-third of the aggregate market value of our common stock held by non-affiliates. As a result of the 2013 Offering, we will be limited in the use of this shelf registration statement until June 2014. We have also filed a registration statement for an equity offering on Form S-1, which has not yet been declared effective. If we raise additional funds by issuing equity or debt securities, either through the sale of securities pursuant to a registration statement or by other means, our existing stockholders may experience dilution, and the new equity or debt securities may have rights, preferences and privileges senior to those of our existing stockholders. If we raise additional funds through collaboration, licensing or other similar arrangements, it may be necessary to relinquish valuable rights to our potential products or proprietary technologies, or grant licenses on terms that are not favorable to us. Without additional funds, we may be forced to delay, scale back or eliminate some of our sales and marketing efforts, research and development activities, or other operations and potentially delay product development in an effort to provide sufficient funds to continue our operations. If any of these events occurs, our ability to achieve our development and commercialization goals would be adversely affected.

Off-Balance Sheet Arrangements, Contractual Obligation and Contingent Liabilities and Commitments

As of September 30, 2013, we did not have any off-balance sheet financing arrangements.

See Note 7, Commitments and Contingencies, of our Notes to Unaudited Financial Statements for information regarding commitments and contingencies.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We do not use derivative financial instruments in our investment portfolio and have no foreign exchange contracts. Our financial instruments consist of cash and cash equivalents. We consider investments that, when purchased, have a remaining maturity of 90 days or less to be cash equivalents. The primary objectives of our investment strategy are to preserve principal, maintain proper liquidity to meet operating needs, and maximize yields. To minimize our exposure to an adverse shift in interest rates, we invest mainly in cash equivalents and short-term investments with a maturity of twelve months or less and maintain an average maturity of twelve months or less. We do not believe that a notional or hypothetical 10% change in interest rate percentages would have a material impact on the fair value of our investment portfolio or our interest income.

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures. Our principal executive officer and principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) as of September 30, 2013, have concluded that, based on such evaluation, our disclosure controls and procedures were effective 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 SEC’s rules and forms, and is accumulated and communicated to our management, including our principal executive and principal financial officers, or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

(b) Changes in Internal Controls. There were no changes in our internal control over financial reporting, identified in connection with the evaluation of such internal control that occurred during the quarter ended September 30, 2013 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
