Note 4 – Financing

At December 31, 2012, financial instruments arising from our financing transactions with YA Global, an accredited investor, included shares of our Series C preferred stock issued in February 2006, Series D preferred stock issued in January 2010, a series of secured convertible debentures issued between August 2006 and July 2012 and various warrants to purchase shares of our common stock. All of our assets are pledged to secure our obligations under the debt securities. At various times, YA Global has assigned or distributed portions of its holdings of these securities to other holders, including persons who are officers of YA Global and its related entities, as well as to other holders who are investors in YA Global’s funds.

Secured Debentures - The underlying agreements for each of the debentures are very similar in form, except in regard to the interest rate, conversion prices, and the number of warrants that were issued in conjunction with each of the debentures. The debentures are convertible into our common stock, at the option of the holder, at the lower of a fixed conversion price per share or a percentage of the lowest volume-weighted average price (“VWAP”) for a specified number of days prior to the conversion (the “look-back period”). The conversion is limited such that the holder cannot exceed 9.99% ownership of the outstanding common stock, unless the holder waives their right to such limitation. All of the debentures are secured according to the terms of a Security Pledge Agreement dated August 23, 2006, which was entered into in connection with the first convertible debenture issued to YA Global and which provides YA Global with a security interest in substantially all of our assets. The debentures are also secured by a Patent Security Agreement dated July 29, 2008. On August 13, 2010, our wholly owned subsidiary, NeoMedia Europe GmbH, became a guarantor of all outstanding financing transactions between us and YA Global, through pledges of their intellectual property and other movable assets. As security for our obligations to YA Global, all of our Pledged Property, Patent Collateral and other collateral is affirmed through the several successive Ratification Agreements which have been executed in connection with each of the 2010, 2011 and 2012 financings.

All debentures with YA Global contain provisions for acceleration of principal and interest upon default. Certain debentures also contain default interest rates and conversion prices, as reflected in the table below.

We evaluated the financing transactions in accordance with FASB ASC 815, Derivatives and Hedging, and determined that the conversion features of the Series C and Series D preferred stock and the Debentures were not afforded the exemption for conventional convertible instruments due to their variable conversion rates. The contracts have no explicit limit on the number of shares issuable so they did not meet the conditions set forth in current accounting standards for equity classification. Accordingly, either the embedded derivative instruments, including the conversion option, must be bifurcated and accounted for as derivative instrument liabilities or, as permitted by FASB ASC 815-15-25-4, Recognition of Embedded Derivatives, the instruments may be carried in their entirety at fair value.

At inception, we elected to bifurcate the embedded derivatives related to the Series C and Series D preferred stock and certain debentures, while electing the fair value option for the March 2007, August 2007, April 2008, May 2008 and April 2012 Debentures. FASB ASC 825, Financial Instruments, allows us to elect the fair value option for recording financial instruments when they are initially recognized or if there is an event that requires re-measurement of the instruments at fair value, such as a significant modification of the debt.

On May 25, 2012, the terms of the debentures held by YA Global were modified to extend the stated maturity dates to August 1, 2013 and reduce the interest rates to 9.5% per year, with interest being payable on the maturity date in cash or, provided certain equity conditions are satisfied, in shares of our Common Stock at the applicable conversion price. As discussed below, in February 2013, the maturity dates of the debentures held by YA Global was further extended to August 2014. Because the effect of the modifications in 2012 exceeded a significance threshold relative to cash flows prescribed by ASC 470-50, Debt Modifications and Extinguishments, the modifications of the amounts due under these arrangements were accounted for as extinguishments, whereby the existing debentures were considered to be retired and new debentures issued. The existing instruments were first adjusted to fair value as of May 25, 2012 using the interest rate and maturity date prior to the amendment. The fair value of the new instruments was then calculated using the modified interest rate and maturity date to determine the fair value of the instrument subsequent to the amendment. The differences in the fair values before and after the amendment were recorded as an extinguishment loss of approximately $27.5 million in the accompanying 2012 statements of operations. Although the maturity date of the debentures held by YA Global has been extended to August 2014, the liabilities related to the debentures continue to be reflected as current liabilities in the accompanying 2012 consolidated balance sheet because we do not have sufficient authorized shares to permit conversion and, accordingly, could be required to settle the liabilities in cash.

As of the date of the modification, we have elected to carry all modified debentures at the fair value of the hybrid instrument with changes in the fair value of the debentures charged or credited to income each period.

The following table summarizes the significant terms of each of the debentures for which the entire hybrid instrument is recorded at fair value as of December 31, 2012:

Total	$	28,887

At December 31, 2012, $25,717 of the face value of debentures was held by YA Global and $3,170 was held by other investors.

For the portion of the debentures held by investors other than YA Global (which debentures were not modified on May 25, 2012) and for the Series C and Series D preferred stock, the election to carry the instruments at fair value in their entirety is not available. Accordingly, we continue to bifurcate the compound embedded derivatives related to the Series C and Series D preferred stock and these debentures and carry these financial instruments as liabilities in the accompanying balance sheet. Significant components of the compound embedded derivative include (i) the embedded conversion feature, (ii) down-round anti-dilution protection features and (iii) default, non-delivery and buy-in puts, all of which were combined into one compound instrument that is carried at fair value as a derivative liability. Changes in the fair value of the compound derivative liability are charged or credited to income each period.

The table below summarizes the significant terms of the debentures that are carried at their amortized cost and for which the compound embedded derivative is bifurcated and accounted for as a derivative liability as of December 31, 2012:

						Conversion Price – Lower of Fixed Price or Percentage of VWAP for Look-back Period

Conversions and Repayments–Our preferred stock and convertible debentures are convertible into shares of our common stock. Upon conversion of any of the convertible financial instruments in which the compound embedded derivative is bifurcated, the carrying amount of the debt, including any unamortized premium or discount, and the related derivative instrument liability are credited to the capital accounts upon conversion to reflect the stock issued and no gain or loss is recognized. For instruments that are recorded in their entirety at the fair value of the hybrid instrument, the fair value of the hybrid instrument converted is credited to the capital accounts upon conversion to reflect the stock issued and no gain or loss is recognized.

The following table provides a summary of the preferred stock conversions that have occurred since inception and the number of common shares issued upon conversion.

			Preferred		Preferred		Common
	Preferred shares		shares		shares		shares
	issued		converted		remaining		issued
	(in thousands)
Series C preferred stock		22		17		5		273,382
Series D preferred stock		25		22		3		245,162

During the fourth quarter of 2012, we repaid $450,000 in outstanding principal and approximately $31,000 in accrued interest which resulted in a decrease of approximately $694,000 in the overall fair value of the hybrid instruments.

The outstanding principal and accrued interest for the debentures as of December 31, 2012 is reflected in the following table in addition to the principal and interest converted since inception and the number of common shares issued upon conversion.

Warrants - YA Global holds warrants to purchase shares of our common stock that were issued in connection with the convertible debentures and the Series C and Series D preferred stock. The warrants are exercisable at a fixed exercise price which, from time to time, has been reduced due to anti-dilution provisions when the Company has entered into subsequent financing arrangements with a lower price. The exercise prices may be reset again in the future if we subsequently issue stock or enter into a financing arrangement with a lower price. In addition, upon each adjustment in the exercise price, the number of warrant shares issuable is adjusted to the number of shares determined by multiplying the warrant exercise price in effect prior to the adjustment by the number of warrant shares issuable prior to the adjustment divided by the warrant exercise price resulting from the adjustment.

The warrants issued to YA Global do not meet all of the established criteria for equity classification in FASB ASC 815-40, Derivatives and Hedging – Contracts in Entity’s Own Equity, and accordingly, are recorded as derivative liabilities at fair value. Changes in the fair value of the warrants are charged or credited to income each period.

2012 Financing Transactions – During 2012, we entered into Agreements to issue and sell six debentures to YA Global in the aggregate principal amount of $2,650,000. The debentures are convertible, at the option of the holder, at a conversion price equal to the lesser of (i) $0.10 or (ii) 95% of the lowest closing bid price of our common stock for the 60 trading days preceding the date of conversion. Except for the June 1, 2012 and July 20, 2012 debentures, at inception, all the debentures had an interest rate of 14% per year and had a maturity date of July 29, 2012. Subsequent to the May 25, 2012 modification, all the debentures bear interest at 9.5% and mature on August 1, 2013. We have the right to redeem a portion or all amounts outstanding under the debentures at a redemption premium of 10%, plus accrued interest. We also issued warrants to YA Global in conjunction with the debentures. The warrants were issued with an initial fixed exercise price of $0.15 per share; however, as a result of the anti-dilution protection in these warrants, the issuance of subsequent debentures for a lower price resets the fixed exercise price of the warrants to the lower price and adjusts the number of warrant shares issuable. All warrants issued during 2012 have a term of five years.

The following table provides a summary of the allocation of the components of the new debentures and warrants issued during the year ended December 31, 2012. The hybrid debt instruments were valued using a Monte Carlo Simulation valuation method and the warrants were valued using a binomial lattice option valuation method. Significant assumptions used to value the hybrid debt instruments and warrants as of inception of the financings are also provided in the table below.

Fair value disclosures

Bifurcated Embedded Derivative Instruments – Series C and Series D preferred stock and Convertible Debentures held by investors other than YA Global - For financings in which the embedded derivative instruments are bifurcated and recorded separately, the compound embedded derivative instruments are valued using a Monte Carlo Simulation methodology because that model embodies certain relevant assumptions (including, but not limited to, interest rate risk, credit risk, and conversion/redemption privileges) that are necessary to value these complex derivatives.

The conversion price in each of the convertible debentures is subject to adjustment for down-round, anti-dilution protection. Accordingly, if we sell common stock or common share indexed financial instruments below the stated or variable conversion price of the debenture, the conversion price adjusts to that lower amount.

The assumptions included in the calculations are highly subjective and subject to interpretation. Assumptions used as of December 31, 2012 included exercise estimates/behaviors and the following other significant estimates: (i) Preferred Stock: remaining term of 0.58 years, equivalent volatility of 91%, equivalent interest rate of 8%, equivalent credit-risk adjusted rate of 6.9% and anti-dilution adjusted conversion price of $0.002037, (ii) Convertible Debentures: Anti-dilution adjusted conversion price of $0.001995. Equivalent amounts reflect the net results of multiple modeling simulations that the Monte Carlo Simulation methodology applies to underlying assumptions.

Due to the variability of the conversion prices, fluctuations in the trading market price of our common stock may result in significant variations to the calculated conversion price. For each debenture, we analyze the ratio of the conversion price (as calculated based on the percentage of VWAP for the appropriate look-back period) to the trading market price for a period of time equal to the term of the debenture to determine the average ratio for the term of the note. Each quarter, the ratio in effect on the date of the valuation is compared with the average ratio over the term of the debenture to determine if the calculated conversion price is representative of past trends or if it is considered unrepresentative due to a large fluctuation in the Common Stock price over a short period of time. If the calculated conversion price results in a ratio that deviates significantly from the average ratio over the term of the agreement, the average ratio of the conversion price to the trading market price is then multiplied by the current trading market price to determine the variable conversion price for use in the fair value calculations. This variable conversion price is then compared with the fixed conversion price and, as required by the terms of the debentures, the lower of the two amounts is used as the conversion price in the Monte Carlo Simulation model used for valuation purposes. On December 31, 2012, the fixed conversion price for each of the debentures was equal to or higher than the calculated variable conversion price. Accordingly, the variable conversion price was used in the Monte Carlo Simulation model. This analysis is performed each quarter to determine if the calculated conversion price is reasonable for purposes of determining the fair value of the embedded conversion features (for instruments recorded under FASB ASC 815-15-25-1) or the fair value of the hybrid instrument (for instruments recorded under FASB ASC 815-15-25-4).

The following table reflects the face value of the instruments, their amortized carrying value and the fair value of the separately-recognized compound embedded derivative, as well the number of common shares into which the instruments are convertible as of December 31, 2012 and 2011.

The terms of the embedded conversion features in the convertible instruments presented above provide for variable conversion rates that are indexed to our quoted common stock price. As a result, the number of indexed shares is subject to continuous fluctuation. For presentation purposes, the number of shares of common stock into which the embedded conversion feature of the Series C and Series D preferred stock was convertible as of December 31, 2012 and 2011 was calculated as face value plus assumed dividends (if declared), divided by the lesser of the fixed rate or the calculated variable conversion price using the 125 day look-back period. The number of shares of common stock into which the embedded conversion feature in the convertible debentures was convertible as of December 31, 2012 and 2011 was calculated as the face value of each instrument divided by the variable conversion price using the appropriate look-back period.

As discussed above, on May 25, 2012, the terms of the debentures held by YA Global were modified to extend the stated maturity dates to August 1, 2013 and those debentures are now accounted for as hybrid instruments and are carried in their entirety at fair value. The debentures outstanding at December 31, 2012 of $53,000 shown above represent a portion of the debentures issued to YA Global which had previously been transferred by YA Global to other parties. These debentures were not modified and continued to mature on July 29, 2012. At December 31, 2012 the debentures had not yet been converted or repaid.

Changes in the fair value of derivative instrument liabilities related to the bifurcated embedded derivative features of convertible instruments not carried at fair value are reported as “Gain (loss) from change in fair value of derivative liability – Series C and Series D preferred stock and debentures” in the accompanying consolidated statements of operations.

Hybrid Financial Instruments Carried at Fair Value –- Since inception, the March 2007, August 2007, April 2008, May 2008 and April 2012 convertible debentures have been recorded in their entirety at fair value as hybrid instruments in accordance with FASB ASC 815-15-25-4 with subsequent changes in fair value charged or credited to income each period. As of May 25, 2012, we elected the fair value option for all other convertible debentures held by YA Global upon a re-measurement date that was triggered by significant modifications of the financial instruments.

Because these debentures are carried in their entirety at fair value, the value of the embedded conversion feature is embodied in those fair values. At inception, the March 2007, August 2007, April 2008 and May 2008 debentures were valued using the common stock equivalent approach. For the April 26, 2012 debenture and, effective May 25, 2012 for all other debentures, the Company changed its method of estimating the fair value of the hybrid instrument to consider the present value of the cash flows of the instrument, using a risk-adjusted interest rate, enhanced by the value of the conversion option, valued using a Monte Carlo model. This method was considered by our management to be the most appropriate method of encompassing the credit risk and exercise behavior that a market participant would consider when valuing the hybrid financial instrument. Inputs used to value the hybrid instruments as of December 31, 2012 included: (i) present value of future cash flows for the debenture using a risk adjusted interest rate of 6.91%, (ii) remaining term of 0.58 years, (iii) equivalent volatility of 91%, equivalent interest rate of 9.5%, equivalent credit-risk adjusted rate of 6.91% and anti-dilution adjusted conversion prices ranging from $0.00189 - $0.00523.

The following table reflects the face value of the financial instruments, the fair value of the hybrid financial instrument and the number of common shares into which the instruments are convertible as of December 31, 2012 and 2011.

The warrants are valued using a binomial lattice option valuation methodology because that model embodies all of the significant relevant assumptions that address the features underlying these instruments. Significant assumptions used in this model as of December 31, 2012 included an expected life equal to the remaining term of the warrants, an expected dividend yield of zero, estimated volatility ranging from 83% to 181%, and risk-free rates of return of 0.05% to 0.72%. For the risk-free rates of return, we use the published yields on zero-coupon Treasury Securities with maturities consistent with the remaining term of the warrants and volatility is based upon our expected Common Stock price volatility over the remaining term of the warrants. As a result of the anti-dilution provisions, the fixed exercise price of the warrants has been reset equal to the lowest price of any subsequently issued common share indexed instruments with a conversion price below the previously stated exercise price of the warrant.

Changes in the fair value of the warrants are reported as "(Gain) loss from change in fair value of derivative liability - warrants" in the accompanying consolidated statements of operations. The changes in the fair value of the warrants were as follows:

Reconciliation of changes in fair value – Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to their fair value measurement. Our derivative financial instruments that are measured at fair value on a recurring basis are all measured at fair value using Level 3 inputs. Level 3 inputs are unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

The following represents a reconciliation of the changes in fair value of financial instruments measured at fair value using Level 3 inputs and changes in the fair value of hybrid instruments carried at fair value during the year ended December 31, 2012:

Estimating fair values of derivative financial instruments requires the development of significant and subjective estimates that may, and are likely to, change over the duration of the instrument with related changes in internal and external market factors. In addition, valuation techniques are sensitive to changes in the trading market price of our common stock, which has a high estimated historical volatility. Because derivative financial instruments are initially and subsequently carried at fair values, our income will reflect the volatility in these estimate and assumption changes.

Subsequent events

On February 4, 2013, we entered into a Debenture Extension Agreement with YA Global to extend the maturity dates of the secured convertible debentures to August 1, 2014. In addition, effective February 1, 2013, 1.4 billion of the 1.9 billion warrants held by YA Global were cancelled. The exercise price of the remaining 499,990,063 warrants was reduced to $0.0001 per share.

Subsequent to December 31, 2012, holders of convertible debentures have converted $1,445,978 of principal and accrued interest on those debentures into 864,244,887 shares of our common stock.
