Description Of Business [Abstract]
Description Of Business	1. Description of Business Stereotaxis designs, manufactures and markets the Epoch Solution, which is an advanced remote robotic navigation system for use in a hospital’s interventional surgical suite, or “interventional lab”, that we believe revolutionizes the treatment of arrhythmias and coronary artery disease by enabling enhanced safety, efficiency and efficacy for catheter-based, or interventional, procedures. The Epoch Solution is comprised of the Niobe ES Robotic Magnetic Navigation System (“Niobe ES system”), Odyssey Information Management Solution (“Odyssey Solution”), and the Vdrive Robotic Navigation System (“Vdrive system”). The Niobe ES system is the latest generation of the Niobe Robotic Magnetic Navigation System (“Niobe system”), which is designed to enable physicians to complete more complex interventional procedures by providing image guided delivery of catheters and guidewires through the blood vessels and chambers of the heart to treatment sites. This is achieved using externally applied magnetic fields that govern the motion of the working tip of the catheter or guidewire, resulting in improved navigation, efficient procedures and reduced x-ray exposure. In addition to the Niobe system and its components, Stereotaxis also has developed the Odyssey Solution, which consolidates all lab information enabling doctors to focus on the patient for optimal procedure efficiency. The system also features a remote viewing and recording capability called the Odyssey Cinema solution, which is an innovative solution delivering synchronized content for optimized workflow, advanced care and improved productivity. This tool includes an archiving capability that allows clinicians to store and replay entire procedures or segments of procedures. This information can be accessed from locations throughout the hospital local area network and over the global Odyssey Network providing physicians with a tool for clinical collaboration, remote consultation and training. Our Vdrive system provides navigation and stability for diagnostic and therapeutic devices designed to improve interventional procedures. The Vdrive system complements the Niobe ES system control of therapeutic catheters for fully remote procedures and enables single-operator workflow and is sold as two options, the Vdrive system and the Vdrive Duo system. In addition to the Vdrive system and the Vdrive Duo system, we also manufacture and market various disposable components which can be manipulated by these systems. We promote the full Epoch Solution in a typical hospital implementation, subject to regulatory approvals or clearances. The full Epoch Solution implementation requires a hospital to agree to an upfront capital payment and recurring payments. The upfront capital payment typically includes equipment and installation charges. The recurring payments typically include disposable costs for each procedure, equipment service costs beyond the warranty period, and software licenses. In hospitals where the full Epoch Solution has not been implemented, equipment upgrade or expansion can be implemented upon purchasing of the necessary upgrade or expansion. The core components of Stereotaxis systems have received regulatory clearance in the U.S., European Union, Canada, China, Japan and elsewhere. The V-Sono™ ICE catheter manipulator has received U.S. clearance, and the V-Loop™ variable loop catheter manipulator and V-CAS™ catheter advancement system have been submitted for review by the U.S. Food and Drug Administration. Since our inception, we have generated significant losses. As of June 30, 2014 we had incurred cumulative net losses of approximately $459.5 million. In May 2011, the Company introduced the Niobe ES system and as of June 30, 2014, the Company had an installed base of 113 Niobe ES systems and has received positive feedback from the physicians at these sites. Between 2011 and 2013, the Company implemented a wide ranging plan to rebalance and reduce operating expenses by 15% to 20% on an annual run rate basis. We expect to incur additional losses throughout the remainder of 2014 as we continue the development and commercialization of our products, conduct our research and development activities and advance new products into clinical development from our existing research programs and marketing initiatives. During 2014, we expect operating expenses to be generally consistent with 2013 with additional investment in certain targeted areas. We may be required to raise capital or pursue other financing strategies to continue our operations. Until we can generate significant cash flow from our operations, we expect to continue to fund our operations with cash resources primarily generated from the proceeds of our past and future public offerings, private sales of our equity securities and working capital and equipment financing loans. In the future, we may finance cash needs through the sale of other equity securities or non-core assets, strategic collaboration agreements, debt financings or through distribution rights. We cannot accurately predict the timing and amount of our utilization of capital, which will depend on a number of factors outside of our control. Our existing cash, cash equivalents and borrowing facilities may not be sufficient to fund our operating expenses and capital equipment requirements through the next 12 months, which would require us to obtain additional financing before that time. We cannot assure that additional financing will be available on a timely basis on terms acceptable to us or at all, or that such financing will not be dilutive to our stockholders. If adequate funds are not available to us, we could be required to delay development or commercialization of new products, to license to third parties the rights to commercialize products or technologies that we would otherwise seek to commercialize ourselves or to reduce the sales, marketing, customer support or other resources devoted to our products, any of which could have a material adverse effect on our business, financial condition and results of operations. In addition, we could be required to cease operations.

Summary Of Significant Accounting Policies

2. Summary of Significant Accounting Policies

Basis of Presentation

The accompanying unaudited financial statements of Stereotaxis, Inc. have been prepared in accordance with generally accepted accounting principles for interim financial information and with the instructions to Form 10-Q. Accordingly, they do not include all the disclosures required by U.S. generally accepted accounting principles for complete financial statements. In the opinion of management, they include all adjustments, consisting only of normal recurring adjustments, necessary for a fair presentation of the results for the interim periods presented. Operating results for the six month period ended June 30, 2014 are not necessarily indicative of the results that may be expected for the year ended December 31, 2014 or for future operating periods.

These interim financial statements and the related notes should be read in conjunction with the annual financial statements and notes included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2013 as filed with the Securities and Exchange Commission (SEC) on March 27, 2014.

As described in Note 10, on July 10, 2012, the Company effected a one-for-ten reverse stock split of the Company’s common stock. All information set forth in the financial statements and related notes gives effect to such reverse stock split.

Financial Instruments

The Company measures certain financial assets and liabilities at fair value on a recurring basis, including warrants and debt conversion features. General accounting principles for fair value measurement established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (“Level 1”) and the lowest priority to unobservable inputs (“Level 3”). See Note 11 for additional details.

The following methods and assumptions were used by the Company in estimating its fair value disclosures for other financial instruments as of June 30, 2014 and December 31, 2013.

Cash equivalents, accounts receivable, and accounts payable have carrying values which approximate fair value due to the short maturity or the financial nature of these instruments.

Long and short-term debt fair value estimates are based on estimated borrowing rates to discount the cash flows to their present value. See Note 9 for disclosure of the fair value of debt.

Revenue and Costs of Revenue

The Company accounts for revenue using Accounting Standards Codification Topic 605-25, Multiple-Element Arrangements (“ASC 605-25”).

ASC 605-25 permits management to estimate the selling price of undelivered components of a bundled sale for which it is unable to establish vendor-specific objective evidence (“VSOE”) or third-party evidence (“TPE”). This requires management to record revenue for certain elements of a transaction even though it might not have delivered other elements of the transaction, for which it was unable to meet the requirements for establishing VSOE or TPE. The Company believes that the guidance significantly improves the reporting of these types of transactions to more closely reflect the underlying economic circumstances. This guidance also prohibits the use of the residual method for allocating revenue to the various elements of a transaction and requires that the revenue be allocated proportionally based on the relative estimated selling prices.

Under our revenue recognition policy, a portion of revenue for Niobe systems, Vdrive systems and certain Odyssey systems is recognized upon delivery, provided that title has passed, there are no uncertainties regarding acceptance, persuasive evidence of an arrangement exists, the sales price is fixed and determinable, and collection of the related receivable is reasonably assured. Revenue is recognized for other types of Odyssey systems upon completion of installation, since there are no qualified third party installers. When installation is the responsibility of the customer, revenue from system sales is recognized upon shipment since these arrangements do not include an installation element or right of return privileges. The Company does not recognize revenue in situations in which inventory remains at a Stereotaxis warehouse or in situations in which title and risk of loss have not transferred to the customer. Amounts collected prior to satisfying the above revenue recognition criteria are reflected as deferred revenue. Revenue from services and license fees, whether sold individually or as a separate unit of accounting in a multiple-deliverable arrangement, is deferred and amortized over the service or license fee period, which is typically one year. Revenue from services is derived primarily from the sale of annual product maintenance plans. We recognize revenue from disposable device sales or accessories upon shipment and establish an appropriate reserve for returns. The return reserve, which is applicable only to disposable devices, is estimated based on historical experience which is periodically reviewed and updated as necessary. In the past, changes in estimate have had only a de minimis effect on revenue recognized in the period. We believe that the estimate is not likely to change significantly in the future.

Costs of systems revenue include direct product costs, installation labor and other costs, estimated warranty costs, and initial training and product maintenance costs. These costs are recorded at the time of sale. Costs of disposable revenue include direct product costs and estimated warranty costs and are recorded at the time of sale. Cost of revenue from services and license fees are recorded when incurred.

Share-Based Compensation

The Company accounts for its grants of stock options, stock appreciation rights, restricted shares, and restricted stock units and for its employee stock purchase plan in accordance with the provisions of general accounting principles for share-based payments. These accounting principles require the determination of the fair value of the share-based compensation at the grant date and the recognition of the related expense over the period in which the share-based compensation vests.

The Company utilizes the Black-Scholes valuation model to determine the fair value of stock options and stock appreciation rights at the date of grant. The resulting compensation expense is recognized over the requisite service period, which is generally four years. Compensation expense is recognized only for those awards expected to vest, with forfeitures estimated based on the Company’s historical experience and future expectations. Restricted shares granted to employees are valued at the fair market value at the date of grant. The Company amortizes the fair market value to expense over the service period. If the shares are subject to performance objectives, the resulting compensation expense is amortized over the anticipated vesting period and is subject to adjustment based on the actual achievement of objectives.

Net Loss per Common Share (“EPS”)

Basic and diluted net loss per common share (“EPS”) is computed by dividing the net loss for the period by the weighted average number of common shares outstanding during the period.

The following table sets forth the computation of basic and diluted EPS:


	Three months ended June 30,				Six months ended June 30,
	2014		2013		2014		2013
Numerator:
Numerator for basic EPS	$	(1,941,479)	$	(3,006,792)	$	(6,081,326)	$	(7,926,939)
Numerator for diluted EPS	$	(1,941,479)	$	(3,006,792)	$	(6,081,326)	$	(7,926,939)
Denominator:
Denominator for basic EPS—weighted average shares		19,631,469		8,188,837		19,483,603		8,102,087
Denominator for diluted EPS		19,631,469		8,188,837		19,483,603		8,102,087
Basic EPS	$	(0.10)	$	(0.37)	$	(0.31)	$	(0.98)
Diluted EPS	$	(0.10)	$	(0.37)	$	(0.31)	$	(0.98)

In addition, the Company did not include any portion of unearned restricted shares, outstanding options, stock appreciation rights or warrants in the calculation of diluted loss per common share because all such securities are anti-dilutive for all periods presented. The application of the two-class method of computing earnings per share under general accounting principles for participating securities is not applicable during these periods because the Company’s unearned restricted shares do not contractually participate in its losses.

As of June 30, 2014, the Company had 509,955 shares of common stock issuable upon the exercise of outstanding options and stock appreciation rights at a weighted average exercise price of $19.04 per share and 2,197,883 shares of common stock issuable upon the exercise of outstanding warrants at a weighted average exercise price of $6.12 per share. The Company had no unearned restricted shares outstanding for the three and six months ended June 30, 2014.

Recently Issued Accounting Pronouncements

In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update (“ASU” or “Update”) No. 2014-09, "Revenue from Contracts with Customers," which converges the FASB's and the International Accounting Standards Board's current standards on revenue recognition. The standard provides companies with a single model to use in accounting for revenue arising from contracts with customers and supersedes current revenue guidance. The standard is effective for annual and interim periods beginning after December 15, 2016. Early adoption is not permitted. The standard permits companies to either apply the adoption to all periods presented, or apply the requirements in the year of adoption through a cumulative adjustment. We are currently evaluating the impact of adopting this accounting standard update on our financial statements and disclosures.

In February 2013, the FASB issued Update 2013-02, “Comprehensive Income: Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income” which adds new disclosure requirements for items reclassified out of accumulated other comprehensive income (“AOCI”). The update requires that the Company present either in a single note or parenthetically on the face of the financial statements, the effect of significant amounts reclassified from each component of AOCI based on its source and the income statement line items affected by the reclassification. The guidance is effective for interim and annual reporting periods beginning on or after December 15, 2012. As the Company has no items of other comprehensive income, the Company is not required to report accumulated other comprehensive income.

Debt outstanding consists of the following:


	June 30, 2014		December 31, 2013
	Carrying	Estimated	Carrying	Estimated
	Amount	Fair Value	Amount	Fair Value

Healthcare Royalty Partners debt	18,506,921	18,506,921	18,531,211	18,531,211
Total debt	18,506,921	18,506,921	18,531,211	18,531,211
Less current maturities	—	—	(49,733)	(49,733)
Total long term debt	$ 18,506,921	$ 18,506,921	$ 18,481,478	$ 18,481,478

In accordance with general accounting principles for fair value measurement, the Company’s debt and credit facilities were measured at fair value as of June 30, 2014 and December 31, 2013. Long-term debt fair value estimates are based on estimated borrowing rates to discount the cash flows to their present value (Level 3).

Revolving line of credit

On March 29, 2013, the Company amended its agreement with its primary lender, Silicon Valley Bank, to extend the maturity date of the $13 million working capital line of credit from March 31, 2013 to June 30, 2013. The Company also received from stockholders, who at the time were affiliates of two current and former members of our board of directors (the “Lenders”) and were considered to be related parties, an extension of their commitment to provide $3 million in loan guarantees until June 30, 2013. As a result of this extension, the Company issued the Lenders warrants to purchase 113,636 shares of common stock at $1.98 per share. Under the facility the Company was required to maintain a minimum “tangible net worth” and liquidity ratio as defined in the agreement. Interest on the facility accrued at the rate of prime plus 0.5% subject to a floor of 6% for the amount under guarantee and prime plus 1.75% subject to a floor of 7% for the remaining amounts.

On June 28, 2013, the Company amended its agreement with its primary lender. The amendment extended the maturity date of the working capital line of credit from June 30, 2013 to July 31, 2013, and decreased the amount of available advances from $13 million to $6 million. In addition, the primary lender waived the testing of the tangible net worth and liquidity ratio financial covenants under the Amended Loan Agreement for the period ended June 30, 2013. The Company and the Lenders also agreed to extend until July 31, 2013 the $3 million guarantee. As a result of this extension, the Company issued the Lenders warrants to purchase 48,387 shares of common stock at $1.55 per share.

On July 31, 2013, the Company amended its agreement with its primary lender. The amendment extended the maturity date of the working capital line of credit from July 31, 2013 to August 31, 2013. In addition, the primary lender waived the testing of the liquidity ratio financial covenant under the Amended Loan Agreement for the period ended July 31, 2013. The Company and the Lenders also agreed to extend until August 31, 2013 the $3 million guarantee. As a result of this extension, the Company issued the Lenders warrants to purchase 14,313 shares of common stock at $5.24 per share.

On August 30, 2013, the Company amended its agreement with its primary lender. The amendment extended the maturity date of the working capital line of credit from August 31, 2013 to March 31, 2014. In addition, the Company and the primary lender agreed to a reduction in the revolving credit line from $6.0 million to $3.0 million, the elimination of the $3.0 million sublimit guaranteed by the Lenders, and release of the guarantees by the Lenders in favor of the primary lender. The amendment eliminated the prepayment premium for the prepayment of the term loan and modified the financial covenants to (a) eliminate the minimum tangible net worth covenant, (b) substitute in lieu thereof an EBITDA test, requiring the Company to maintain a minimum EBITDA of no less than (no worse than) (i) negative $4.0 million for the trailing three-month period ending September 30, 2013 and (ii) negative $3.0 million for the trailing three-month period ending December 31, 2013, in each case tested quarterly on a trailing three month basis, and (c) revise the liquidity ratio covenant to require the Company to maintain a liquidity ratio of greater than 2:1, excluding certain short term advances from the calculation.

On March 28, 2014, the Company amended its agreement with its primary lender. The amendment extended the maturity date of the working capital line of credit from March 31, 2014 to March 31, 2015. In addition, the Company and the primary lender agreed to an increase in the revolving credit line from $3.0 million to $10.0 million and modified the financial covenants to (a) eliminate the EBITDA test, (b) substitute in lieu thereof a minimum tangible net worth test, requiring the Company to maintain a minimum tangible net worth of not less than (no worse than) negative $21 million, with such minimum requirement subject to increase under certain circumstances as described in the agreement, and (c) revise the liquidity ratio covenant to require the Company to maintain a liquidity ratio of greater than 1.75:1.00, excluding certain short term advances from the calculation.

As of June 30, 2014, the Company had no outstanding debt under the revolving line of credit. Draws on the line of credit are made based on the borrowing capacity one week in arrears. As of June 30, 2014 the Company had a borrowing capacity of $3.8 million based on the Company’s collateralized assets. As such, the Company had the ability to borrow $3.8 million under the revolving line of credit at June 30, 2014.

Term note

Under the 2010 amendment to the loan agreement, the Company entered into a $10 million term loan maturing on December 31, 2013, with $2 million of principal due in 2011 and $4 million of principal due in each of 2012 and 2013. Interest on the term loan accrued at the rate of the primary lender’s prime plus 3.5% until September 2011, at which point it was adjusted to the lender’s prime plus 5.5%. Under this agreement, the Company provided its primary lender with warrants to purchase 11,111 shares of common stock. The warrants are exercisable at $36.00 per share, beginning on December 17, 2010 and expiring on December 17, 2015. The fair value of these warrants of $228,332, calculated using the Black-Scholes method, was deferred and amortized to interest expense ratably over the life of the term loan. The term note was paid in full in September 2013.

Healthcare Royalty Partners Debt

In November 2011, the Company entered into a loan agreement with Healthcare Royalty Partners. Under the agreement the Company borrowed from Healthcare Royalty Partners $15 million. The Company was permitted to borrow up to an additional $5 million in the aggregate based on the achievement by the Company of certain milestones related to Niobe system sales in 2012. On August 8, 2012, the Company borrowed an additional $2.5 million based upon achievement of a milestone related to Niobe system sales for the three months ended June 30, 2012. On January 31, 2013, the Company borrowed an additional $2.5 million based upon achievement of a milestone related to Niobe system sales for the twelve months ended December 31, 2012. The loan will be repaid through, and secured by, royalties payable to the Company under its Development, Alliance and Supply Agreement with Biosense Webster, Inc. The Biosense Agreement relates to the development and distribution of magnetically enabled catheters used with Stereotaxis' Niobe system in cardiac ablation procedures. Under the terms of the Agreement, Healthcare Royalty Partners will be entitled to receive 100% of all royalties due to the Company under the Biosense Agreement until the loan is repaid. The loan is a full recourse loan, matures on December 31, 2018, and bears interest at an annual rate of 16% payable quarterly with royalties received under the Biosense Agreement. If the payments received by the Company under the Biosense Agreement are insufficient to pay all amounts of interest due on the loan, then such deficiency will increase the outstanding principal amount on the loan. After the loan obligation is repaid, the royalties under the Biosense Agreement will again be paid to the Company. The loan is also secured by certain assets and intellectual property of the Company. The Agreement also contains customary affirmative and negative covenants. The use of payments due to the Company under the Biosense Agreement was approved by our primary lender under the Amended Loan Agreement described above.

Subordinated Convertible Debentures

In May 2012, the Company entered into a securities purchase agreement with certain institutional investors whereby the Company agreed to sell an aggregate of approximately $8.5 million in aggregate principal amount of unsecured, subordinated, convertible debentures (the “Debentures”), which became convertible into shares of the Company’s common stock at a conversion price of $3.361 per share (or approximately 2.5 million shares in the aggregate), on July 10, 2012, the date that the Company received shareholder approval for the transaction. The purchasers of the Debentures also received six-year warrants to purchase an aggregate of approximately 2.5 million shares of the Company’s common stock at an exercise price of $3.361 per share (“Convert Warrants”). The Debentures bore interest at 8% per year and were to mature on May 7, 2014. In addition, the Company had the ability to issue shares of its common stock in lieu of cash interest payments under certain circumstances, and following the registration of the shares for resale, the Company issued shares in lieu of cash interest payments.

The Company recorded the Debentures on the balance sheet net of the debt discount. The debt discount of $7.6 million was due to warrants issued in conjunction with the Debentures and the debt conversion features. Upon issuance of the Debentures, the fair value of the warrants and derivative liability were $4.1 million and $3.5 million, respectively. The debt discount was amortized over the life of the loan using the effective interest method and the warrants and derivative liability were recorded at fair value on each reporting period. Refer to Note 11 for additional discussion of the fair value of the warrants.

On August 7, 2013, holders of Convert Warrants exercised all of their Convert Warrants for an aggregate of approximately 2.5 million shares of our common stock, resulting in cash proceeds of approximately $8.5 million. In addition, holders of all of the Debentures exchanged the balance of their unconverted Debentures for an aggregate of approximately 2.7 million shares of the Company’s common stock and additional warrants (the “Exchange Warrants”) to purchase approximately 2.5 million shares, having an exercise price of $3.361 per share. On August 8, 2013, certain former holders of the Debentures exercised Exchange Warrants to purchase an aggregate of 1.4 million shares of common stock in cashless net exercises as provided for in the Exchange Warrants, which resulted in the issuance to such funds of an aggregate of 0.8 million shares of common stock, but no net proceeds to the Company. The Company is relying on the exemption from registration afforded by Section 4(a)(2) of the Securities Act of 1933, as amended, based on representations to the Company made by the warrant holders.

Stockholders' Equity [Abstract]

Stockholders' Equity

10. Stockholders’ Equity

The holders of common stock are entitled to one vote for each share held and to receive dividends whenever funds are legally available and when declared by the Board of Directors subject to the prior rights of holders of all classes of stock having priority rights as dividends and the conditions of the Revolving Credit Agreement. No dividends have been declared or paid as of June 30, 2014.

Listing Transfer to NASDAQ Capital Market

On August 15, 2013, the NASDAQ Listing Qualifications Panel (the “Panel”) granted approval of the Company’s request to transfer its listing to The NASDAQ Capital Market® from The NASDAQ Global Market®. The Company’s securities began trading on the NASDAQ Capital Market effective August 19, 2013.

Reverse Stock Split

On July 10, 2012, the Company filed a Certificate of Amendment to our Amended and Restated Certificate of Incorporation to implement a one-for-ten reverse split of our common stock (the “Reverse Stock Split”). The ratio for the Reverse Stock Split was determined by our Board of Directors pursuant to the approval of the stockholders at the Company’s special meeting of stockholders held on July 10, 2012, authorizing the Board to effect a reverse stock split within a range of one-for-four to one-for-ten shares of the Company’s common stock. The Reverse Stock Split was effective as of July 10, 2012, and the Company’s common stock began trading on the NASDAQ Global Market on a post-split basis on July 11, 2012.

As a result of the Reverse Stock Split, each ten shares of the Company’s issued and outstanding common stock were automatically combined and converted into one issued and outstanding share of common stock. The Reverse Stock Split affected all issued and outstanding shares of the Company’s common stock, as well as common stock underlying stock options, stock appreciation rights, restricted stock, restricted stock units, warrants and convertible debentures outstanding immediately prior to the effectiveness of the Reverse Stock Split. The Reverse Stock Split reduced the number of shares of the Company’s common stock outstanding from approximately 78 million to 7.8 million at the time of the Reverse Stock Split. In addition, the Amendment increased the number of authorized shares of the Company’s common stock from 100 million to 300 million. The Reverse Stock Split did not alter the par value of common stock, which remained $0.001 per share, or modify any voting rights or other terms of the Company’s common stock. Unless otherwise indicated, all information set forth herein gives effect to such Reverse Stock Split.

Private Offerings of Common Stock

In May 2012, the Company entered into a Stock and Warrant Purchase Agreement with certain institutional investors whereby it agreed to sell an aggregate of approximately 2.17 million shares of the Company's common stock (the “PIPE Common Stock”) at a price of $3.361 per share, together with six-year warrants at a price of $1.25 per share to purchase an aggregate of approximately 2.17 million shares of common stock having an exercise price of $3.361 per share (the “PIPE Warrants”). Each purchaser received a PIPE Warrant to purchase one share of common stock for every share of PIPE Common Stock purchased. Net proceeds from the sale of the securities were approximately $9.1 million, after placement agent fees and other offering expenses. The Company used the funds to repay $7 million of the revolving credit facility guaranteed by the Lenders and plans to use the balance for working capital and general corporate purposes.

On August 7, 2013, venture funds affiliated with Sanderling Ventures received an aggregate of 183,478 shares of common stock based upon the cashless exercise of warrants to purchase an aggregate of 262,450 shares of common stock. These warrants were comprised of 75,758 warrants with an exercise price of $1.98 per share, 156,204 warrants with an exercise price of $3.361 per share and 30,488 warrants with an exercise price of $4.10 per share. The warrants were issued by the Company in private placements in 2012 and 2013 in connection with the extension of previously disclosed guarantees.

On August 13, 2013, venture funds affiliated with Sanderling Ventures exercised PIPE Warrants to purchase an aggregate of 650,619 shares of common stock in a cashless net exercise as provided for in the PIPE Warrants, which resulted in the issuance to such funds of an aggregate of 308,194 shares of common stock. As a result, there were no net proceeds to the Company.

On August 16, 2013, certain affiliates of Franklin Templeton exercised PIPE Warrants to purchase an aggregate of 650,618 shares of common stock for cash. The Company received an aggregate of $2,186,727 gross proceeds from the sale.

On August 16, 2013, Alafi Capital Company exercised PIPE Warrants to purchase an aggregate of 261,241 shares of common stock for cash. The Company received an aggregate of $878,031 gross proceeds from the sale.

On November 27, 2013, the Company announced the results of its previously announced offering of subscription rights to purchase shares of its common stock, par value $0.001 per share. Pursuant to the rights offering, subscription rights to purchase approximately 3.4 million shares of common stock were exercised, resulting in gross proceeds to Stereotaxis of approximately $10.2 million.

Controlled Equity Offering

In May 2014, the Company entered into a Controlled Equity OfferingSM sales agreement (the “Sales Agreement”), with Cantor Fitzgerald & Co. (“Cantor”), as agent and/or principal, pursuant to which the Company could issue and sell, from time to time, shares of its common stock having an aggregate gross sales price of up to $18.0 million. The Company will pay Cantor a commission of 3.0% of the gross proceeds from any common stock sold through the Sales Agreement.

During the three months ended June 30, 2014, the Company sold an aggregate of 711,959 shares of common stock under the Sales Agreement, at an average price of approximately $3.62 per share for gross proceeds of $2.6 million and net proceeds of $2.5 million, after deducting Cantor’s commission. As of June 30, 2014, $15.4 million of common stock remained available to be sold under this facility, subject to certain conditions as specified in the Sales Agreement.

Stock Award Plans

The Company has various stock plans that permit the Company to provide incentives to employees and directors of the Company in the form of equity compensation. In August 2012, the Board of Directors adopted a stock incentive plan (the 2012 Stock Incentive Plan) which was subsequently approved by the Company’s stockholders. This plan replaces the 2002 Stock Incentive Plan which expired on March 25, 2012. On June 10, 2014, the shareholders approved an amendment to the Stereotaxis, Inc. 2012 Stock Incentive Plan (“Plan”), which was previously approved and adopted by the Compensation Committee of the Board of Directors of the Company on March 27, 2014. The amendment increased the number of shares authorized for issuance under the Plan by one million shares. At June 30, 2014, the Company had 1,303,300 remaining shares of the Company’s common stock to provide for current and future grants under its various equity plans.

At June 30, 2014, the total compensation cost related to options, stock appreciation rights and non-vested stock granted to employees under the Company’s stock award plans but not yet recognized was approximately $2.2 million, net of estimated forfeitures of approximately $2.0 million. This cost will be amortized over a period of up to four years over the underlying estimated service periods and will be adjusted for subsequent changes in estimated forfeitures and anticipated vesting periods.

Fair Value Measurements [Abstract]

Fair Value Measurements

11. Fair Value Measurements

The Company measures certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents and warrants. General accounting principles for fair value measurement established a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets and liabilities (“Level 1”) and the lowest priority to unobservable inputs (“Level 3”). The three levels of the fair value hierarchy are described below:

Level 1: Values are based on unadjusted quoted prices in active markets that are accessible at the measurement date for identical, unrestricted assets or liabilities.

Level 2: Values are based on quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, or other model-based valuation techniques for which all significant assumptions are observable in the market.

Level 3: Values are generated from model-based techniques that use significant assumptions not observable in the market.

The following table sets forth the Company’s assets and liabilities measured at fair value on a recurring basis by level within the fair value hierarchy. As required by the Fair Value Measurements and Disclosures topic of the Accounting Standards Codification, assets and liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value measurement.

The Company’s financial assets consist of cash equivalents invested in money market funds in the amount of $7,313,366 and $11,995,481 at June 30, 2014 and December 31, 2013, respectively. These assets are classified as Level 1 as described above and total interest income recorded for these investments was insignificant during both the six month periods ended June 30, 2014, and June 30, 2013. There were no transfers in or out of Level 1 during the period ended June 30, 2014.

Level 2

The Company does not have any financial assets or liabilities classified as Level 2.

Level 3

In conjunction with its December 29, 2008 registered direct offering, the Company issued warrants to purchase 179,241 shares of the Company’s common stock that contained a provision that required a reduction of the exercise price if certain equity events occurred. Under the provisions of general accounting principles for derivatives and hedging activities and determining whether an instrument (or embedded feature) is indexed to an entity’s own stock, such a reset provision does not meet the exemptions for equity classification and as such, the Company accounts for these warrants as derivative instruments. The calculated fair value of the warrants is classified as a liability and is periodically remeasured with any changes in value recognized in “Other income (expense)” in the Statement of Operations. General accounting principles for determining whether an instrument (or embedded feature) is indexed to an entity’s own stock became effective for the Company as of January 1, 2009. Accordingly, the fair value of the warrants as of that date was reclassified from stockholders’ equity into current liabilities. This tranche of warrants issued in conjunction with the December 2008 registered direct offering were expired as of June 30, 2014.

In the Company’s May 2012 financing transaction, the Company issued subordinated convertible debentures and warrants. The optional conversion feature of the subordinated convertible debentures was classified as a derivative liability within “Warrants and derivative liabilities” on the Company’s balance sheet. The warrants issued in conjunction with the Debentures and PIPE are also considered a liability. Due to the provisions included in the warrant agreements, the warrants do not meet the exemptions for equity classification and as such, the Company accounts for these warrants as derivative instruments. The warrants and derivative liability are periodically remeasured with any changes in value recognized in “Other income (expense)” in the Statements of Operations.

Per the terms of the Debentures agreement, the Company had the ability to require each holder to convert up to 50% of the Debentures if the common stock closed above $15.00, or 100% of the Debentures if the common stock closed above $20.00 (in each case, as adjusted for stock splits, recapitalizations and similar events) during a 20 consecutive trading day period and the resale registration statement had been declared effective by the SEC and was available for the issuance of the common stock upon conversion of the Debentures. In the event of any forced conversion by the Company, the minimum amount that the Company could force the holders to convert was $2.5 million of Debentures in the aggregate. This mandatory redemption clause was classified as a derivative asset within “Prepaid and other current assets” on the Company’s balance sheet. The derivative asset was periodically remeasured with any changes in value recognized in “Other income (expense)” in the Statement of Operations.

Based on the discussion of the Debentures in Note 10, the Debentures along with their derivative liability and asset, and related warrants were extinguished in the third quarter of 2013.

The initial valuation of Exchange warrants were valued as of August 7, 2013 using the following assumptions: 1) volatility of 111%; 2) risk-free interest rate of 1.46%; and 3) a closing stock price of $8.69.

The remaining Exchange warrants were revalued as of June 30, 2014 using the following assumptions: 1) volatility of 150.16%; 2) risk-free interest rate of 1.62%; and 3) a closing stock price of $3.55.

The remaining PIPE warrants were revalued as of June 30, 2014 using the following assumptions: 1) volatility of 157.74%; 2) risk-free interest rate of 1.62%; and 3) a closing stock price of $3.55.

The significant unobservable input used in the fair value measurement of the Company’s warrants is volatility. Significant increases (decreases) in the volatility in isolation would result in significantly higher (lower) liability fair value measurements.

The following table sets forth a summary of changes in the fair value of the Company’s Level 3 financial liabilities for the six month period ended June 30, 2014:


	Warrants issued December 29, 2008	Warrants issued May 2012	Warrants issued August 2013	Total Liabilities
Balance at beginning of period	$ 16,863	$ 1,915,753	$ 3,712,010	$ 5,644,626

Balance at end of period	$ -	$ 1,906,211	$ 3,633,428	$ 5,539,639

The Company currently does not have derivative instruments to manage its exposure to currency fluctuations or other business risks. The Company evaluates all of its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives. All derivative financial instruments are recognized in the balance sheet at fair value.

Financial Instruments

The following methods and assumptions were used by the Company in estimating its fair value disclosures for other financial instruments as of June 30, 2014 and December 31, 2013.

Cash equivalents, accounts receivable, and accounts payable have carrying values which approximate fair value due to the short maturity or the financial nature of these instruments.

Long and short-term debt fair value estimates are based on estimated borrowing rates to discount the cash flows to their present value. See Note 9 for disclosure of the fair value of debt.
