Accounting Policies

For a summary of significant accounting policies (which have not changed from December 31, 2013), see the Company’s Annual Report on Form 10-K for the year ended December 31, 2013.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States requires management to make 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 as well as the reported amount of revenues and expenses during the reporting period. Actual results could differ from these estimates.

Intangible Assets

The Company also reviews its identified intangible assets for impairment whenever events or circumstances indicate that the carrying amount of an asset may not be recoverable. The Company assesses recoverability by reference to future cash flows from the products underlying these intangible assets. If these estimates change in the future, the Company may be required to record impairment charges for these assets. As of March 31, 2014, no impairment was recorded.

Debt Discount

Costs incurred with parties who are providing long-term financing, which generally include the value of warrants or the fair value of an embedded derivative conversion feature, are reflected as a debt discount and are amortized over the life of the related debt. The debt discount attributable to the embedded conversion derivative liability during the three months ended March 31, 2014 and 2013 was $0 and $0, respectively. The Company recorded the accretion of debt discount of $381,000 and $450,000 during the three months ended March 31, 2014 and 2013, respectively. The total unaccreted debt discount at March 31, 2014 was $1,267,000, compared to $1,328,000 at December 31, 2013.

Fair Value of Financial Instruments

The carrying value of cash and cash equivalents, accounts receivable, prepaids, deposits, accounts payable and accrued liabilities, common stock payable, and unearned revenue, approximate their fair values because of the short-term nature of these instruments. Management believes the Company is not exposed to significant interest or credit risks arising from these financial instruments.

Fair value is defined as the exchange price that would be received for an asset or paid to transfer a liability (an exit price) in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value maximize the use of observable inputs and minimize the use of unobservable inputs. The Company utilizes a fair value hierarchy based on three levels of inputs, of which the first two are considered observable and the last unobservable.

•

Level 1 — Quoted prices in active markets for identical assets or liabilities. These are typically obtained from real-time quotes for transactions in active exchange markets involving identical assets.

•

Level 2 — Quoted prices for similar assets and liabilities in active markets; quoted prices included for identical or similar assets and liabilities that are not active; and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets. These are typically obtained from readily-available pricing sources for comparable instruments.

•

Level 3 — Unobservable inputs, where there is little or no market activity for the asset or liability. These inputs reflect the reporting entity’s own beliefs about the assumptions that market participants would use in pricing the asset or liability, based on the best information available in the circumstances.

The following table presents the embedded conversion derivative liability, the Company’s only financial liability measured and recorded at fair value on the Company’s consolidated balance sheets on a recurring basis and their level within the fair value hierarchy as of March 31, 2014 (in thousands):

	March 31, 2014		Level 1		Level 2		Level 3

Embedded conversion derivative liability	$	3,621	$	-	$	-	$	3,621

The following table reconciles, for the three months ended March 31, 2014, the beginning and ending balances for financial instruments that are recognized at fair value in the consolidated financial statements (in thousands):

Balance of embedded conversion derivative liability as of December 31, 2013	$	6,968
Fair value of embedded conversion derivative liabilities at issuance		320
Gain on fair value adjustments to embedded conversion derivative liability		(220)
Reductions in fair value do to conversion of convertible debentures into common stock payable		(3,447)
Balance of embedded conversion derivative liability at March 31, 2014	$	3,621

The fair value of the conversion features are calculated at the time of issuance and the Company records a derivative liability for the calculated value using a Black-Scholes option-pricing model. Changes in the fair value of the derivative liability are recorded in other income (expense) in the consolidated statements of operations. Upon conversion of the convertible debt to stock, the Company reclassifies the related embedded conversion derivative liability to paid in capital. Since the fair value of the embedded conversion derivative liability exceeded the carrying value of the convertible debentures on the issuance date, the convertible debentures were recorded at a full discount. The Company recognizes expense for accretion of the convertible debentures discount over the term of the notes. The Company has considered the provisions of ASC 480, Distinguishing Liabilities from Equity, as the conversion feature embedded in each debenture could result in the note principal being converted to a variable number of the Company’s common shares.

Revenue Recognition

The Company’s revenues are currently derived from the sale of medical equipment products, maintenance contracts and service revenues. Revenues from maintenance contracts are recognized over the term of the contract. Service revenues are recognized upon performance of the services. The Company recognizes revenues from the sale of medical equipment products when earned. Specifically, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred (or services have been rendered), the price is fixed or determinable, and collectability is reasonably assured. The Company obtains a signed customer acceptance after installation is complete for the sale of its Attrius® systems.

In multiple-element arrangements, revenue is allocated to each element based on their relative selling prices. Relative selling prices are based first on vendor specific objective evidence (VSOE), then on third-party evidence of selling price (TPE) when VSOE does not exist, and then on estimated selling price (ESP) when VSOE and TPE do not exist. Because the Company has neither VSOE nor TPE for its products, the allocation of revenue has been based on the Company’s ESPs. The objective of ESP is to determine the price at which the Company would transact a sale if the product was sold on a stand-alone basis. The Company determines ESP by considering the facts and circumstances of the product being sold.
