Basis of Presentation and Use of Estimates

In the opinion of management, the accompanying unaudited condensed financial statements (“condensed financial statements”) have been prepared on a basis consistent with the Company’s December 31, 2012 audited financial statements, and include all adjustments, consisting of only normal recurring adjustments, necessary to fairly state the information set forth therein. The condensed financial statements have been prepared in accordance with U.S. Securities and Exchange Commission (“SEC”) rules for interim financial information, and, therefore, omit certain information and footnote disclosures necessary to present the statements in accordance with generally accepted accounting principles in the United States (“GAAP”). The preparation of the financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues, expenses, and the related disclosures at the date of the financial statements and during the reporting period. Actual results could materially differ from these estimates. These condensed financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Company’s Annual Report on Form 10-K/A for the year ended December 31, 2012, which was filed with the SEC on August 19, 2013. The accompanying condensed balance sheet as of December 31, 2012 has been derived from the audited financial statements at that date, but does not include all information and footnotes required by GAAP for complete financial statements. The results of operations for the three and nine month periods ended September 30, 2013 may not be indicative of the results to be expected for the entire year or any future periods.

Fair Value Measurements

Carrying amounts of the Company’s cash and cash equivalents, accounts receivable and accounts payable and accrued liabilities approximate their fair values due to their short maturities.

The table below reflects the carrying values and the estimated fair values of the Company’s outstanding notes payable at September 30, 2013:

The difference between the carrying value of the related party Boston Scientific convertible notes payable, which is equal to the face value due to troubled debt restructuring accounting, and the estimated fair value is attributable to the fact that no interest is charged per the terms of the convertible notes payable, which is below market. The difference between the carrying value and the fair value of the junior secured notes payable relates primarily to the unamortized debt discount. This discount resulted from the relative fair value assigned to the junior secured notes payable at the time of issuance, as the notes were issued in connection with a unit offering, with the units consisting of a note payable and shares of the Company’s common stock.

The Company measures certain financial assets and liabilities at fair value on a recurring basis. GAAP provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority, referred to as Level 1, to quoted prices in active markets for identical assets and liabilities. The next priority, referred to as Level 2, is given to quoted prices for similar assets or liabilities in active markets or quoted prices for identical or similar assets or liabilities in markets that are not active, that is, markets in which there are few transactions for the asset or liability. The lowest priority, referred to as Level 3, is given to unobservable inputs. See Note 5 for fair value information related to the Company’s derivative liabilities, which are the only assets or liabilities carried at fair value by the Company on a recurring basis at September 30, 2013. The table below reflects the level of the inputs used in the Company’s fair value calculation for instruments carried at fair value.

Derivative Liability for Warrants to Purchase Common Stock

The derivative liability for warrants represents the fair value of warrants issued in connection with private placements of shares of the Company’s common stock (see Note 5). These warrants are presented as liabilities based on certain exercise price reset and net cash settlement provisions. The liability, which is recorded at fair value on the accompanying balance sheets, is calculated utilizing the Monte Carlo simulation valuation method. The change in fair value of these warrants is recognized as other income or expense in the statements of operations.

Inventory

Inventory is carried at the lower of cost (first-in, first-out method) or net realizable value. All items included in inventory relate to the Company’s ClearPoint system. Software license inventory that is not expected to be utilized within the next twelve months is classified as a non-current asset. The Company periodically reviews its inventory for obsolete items and provides a reserve upon identification of potential obsolete items.

Revenue Recognition

The Company’s revenues arise from: (1) the sale of ClearPoint system reusable components; (2) sales of ClearPoint disposable products; and (3) license, development and other service arrangements. The Company recognizes revenue, in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 605-10-S99, “Revenue Recognition,” when persuasive evidence of an arrangement exists, the selling price or fee is fixed or determinable, collection is probable and risk of loss has transferred to the customer. For all sales, the Company requires either a purchase agreement or a purchase order as evidence of an arrangement.

(1)     Sale of ClearPoint system reusable components – Generally, revenues related to ClearPoint system sales are recognized upon installation of the system and the completion of training of at least one of the customer’s physicians, which typically occurs concurrently with the ClearPoint system installation. ClearPoint system reusable components include software. This software is integral to the utility of the ClearPoint system as a whole, and as such, the provisions of FASB ASC 985-605, “Software Revenue Recognition,” are not applicable. Sales of reusable components that have stand-alone value to the customer are recognized when risk of loss passes to the customer. Sales of reusable components to a distributor that has been trained to perform ClearPoint system installations are recognized at the time risk of loss passes to the distributor.

(2)      Sale of ClearPoint disposable products – Revenues from the sale of ClearPoint disposable products utilized in procedures performed using the ClearPoint system are recognized at the time risk of loss passes to the customer, which is generally at shipping point or upon delivery to the customer’s location, depending upon the specific terms agreed upon with the customer.

(3)     License, development other service arrangements - The Company analyzes revenue recognition on an agreement-by-agreement basis as discussed below.

Net Loss Per Share

The Company calculates net loss per share in accordance with FASB ASC 260, “Earnings per Share.” Basic earnings per share (“EPS”) is calculated by dividing the net income or loss attributable to common stockholders by the weighted average number of common shares outstanding for the period, without giving consideration to common stock equivalents. Diluted EPS is computed by dividing the net income or loss attributable to common stockholders by the weighted average number of common shares outstanding for the period plus the weighted average number of dilutive common stock equivalents outstanding for the period determined using the treasury stock method when net income is reported. For all periods presented, since such periods resulted in net losses, diluted net loss per share is the same as basic net loss per share. The following table sets forth potential shares of common stock that are not included in the calculation of diluted net loss per share because to do so would be anti-dilutive as of the end of each period presented:

New Accounting Pronouncements

In February 2013, the FASB issued guidance that requires an entity to disclose information showing the effect of items reclassified from accumulated other comprehensive income on the line items of net income. The provisions of this new guidance were effective prospectively as of the beginning of the Company’s 2013 fiscal year. The adoption of this standard update did not have an impact on the Company’s financial statements for the three or nine months ended September 30, 2013.
