Note 4 - Stock-based Compensation

In accordance with ASC Topic 718, stock-based compensation cost is estimated at the grant date, based on the estimated fair value of the awards, and recognized as expense ratably over the requisite service period of the award for awards expected to vest.

Stock Incentive Plans

Under the Broadcast International, Inc. 2004 Long-Term Incentive Plan (the "2004 Plan"), the board of directors may issue incentive stock options to employees and directors and non-qualified stock options to consultants of the company. Options generally may not be exercised until twelve months after the date granted and expire ten years after being granted. Options granted vest in accordance with the vesting schedule determined by the board of directors, usually ratably over a three-year vesting schedule upon anniversary date of the grant. Should an employee terminate before the vesting period is completed, the unvested portion of each grant is forfeited. We have used the Black-Scholes valuation model to estimate fair value of our stock-based awards, which requires various judgmental assumptions including estimated stock price volatility, forfeiture rates, and expected life. Our computation of expected volatility is based on a combination of historical and market-based implied volatility. The number of unissued stock options authorized under the 2004 Plan at June 30, 2011 was 2,463,251.

The Broadcast International, Inc. 2008 Equity Incentive Plan (the "2008 Plan") has become our primary plan for providing stock-based incentive compensation to our eligible employees and non-employee directors and consultants of the company. The provisions of the 2008 Plan are similar to the 2004 Plan except that the 2008 Plan allows for the grant of share equivalents such as restricted stock awards, stock bonus awards, performance shares and restricted stock units in addition to non-qualified and incentive stock options. We continue to maintain and grant awards under our 2004 Plan which will remain in effect until it expires by its terms. The number of unissued shares of common stock reserved for issuance under the 2008 Plan was 1,365,000 at June 30, 2011.

Stock Options

We estimate the fair value of stock option awards granted beginning January 1, 2006 using the Black-Scholes option-pricing model. We then amortize the fair value of awards expected to vest on a straight-line basis over the requisite service periods of the awards, which is generally the period from the grant date to the end of the vesting period. The Black-Scholes valuation model requires various judgmental assumptions including the estimated volatility, risk-free interest rate and expected option term. Our computation of expected volatility is based on a combination of historical and market-based implied volatility. The risk-free interest rate was based on the yield curve of a zero-coupon U.S. Treasury bond on the date the stock option award was granted with a maturity equal to the expected term of the stock option award. The expected option term is derived from an analysis of historical experience of similar awards combined with expected future exercise patterns based on several factors including the strike price in relation to the current and expected stock price, the minimum vest period and the remaining contractual period.

The fair values for the options granted for the six months ended June 30, 2011 and 2010 were estimated at the date of grant using the Black-Scholes option-pricing model with the following weighted average assumptions:


	Six Months Ended June 30, 2011	Six Months Ended June 30, 2010
Risk free interest rate	1.91%	3.14%
Expected life (in years)	5.54	7.5
Expected volatility	82.03%	80.71%
Expected dividend yield	0.00%	0.00%

The weighted average fair value of options granted during the six months ended June 30, 2011 and 2010 was $0.69 and $0.80, respectively.

Warrants

We estimate the fair value of issued warrants on the date of issuance as determined using a Black-Scholes pricing model. We amortize the fair value of issued warrants using a vesting schedule based on the terms and conditions of each associated underling contract, as earned. The Black-Scholes valuation model requires various judgmental assumptions including the estimated volatility, risk-free interest rate and warrant expected exercise term. Our computation of expected volatility is based on a combination of historical and market-based implied volatility. The risk-free interest rate was based on the yield curve of a zero-coupon U.S. Treasury bond on the date the warrant was issued with a maturity equal to the expected term of the warrant.

The fair values for the warrants issued for the six months ended June 30, 2011 and 2010 estimated at the date of issuance using the Black-Scholes option-pricing model with the following weighted average assumptions:


	Six Months Ended June 30, 2011	Six Months Ended June 30, 2010
Risk free interest rate	2.04%	1.60%
Expected life (in years)	5.00	2.96
Expected volatility	85.82%	89.03%
Expected dividend yield	0.00%	0.00%

The weighted average fair value of warrants issued during the six months ended June 30, 2011 and 2010 was $0.79 and $0.63, respectively.

Net loss for the six months ended June 30, 2011 and 2010 includes $1,786,873 and $695,004, respectively, of non-cash stock-based compensation expense. Restricted stock units and options issued to directors vest immediately. All other restricted stock units, options and warrants are subject to applicable vesting schedules. Expense is recognized proportionally as each award or grant vests.

Included in the $1,786,873 net loss for the six months ended June 30, 2011 are (i) $1,544,000 for 1,400,000 restricted stock units issued to all 5 members of the board of directors, (ii) $167,566 for 600,000 options issued to one individual and one corporation for consulting services, (iii) $14,433 for 426,700 options granted to 31 employees, (iv) $4,263 for 8,700 options granted to 15 of our non-employee installation technicians and (iv) $56,611 resulting from the vesting of unexpired options and warrants issued prior to January 1, 2011.

Included in the $695,004 net loss for the six months ended June 30, 2010 are (i) $80,000 for 100,000 options granted to a member of the board of directors, (ii) $28,500 for 50,000 warrants issued to a new member of our advisory board, (iii) $104,075 for 210,000 warrants issued to five individuals for consulting services, (iv) $388,429 resulting from the vesting of unexpired options and warrants issued prior to January 1, 2010 and (v) $94,000 for 100,000 restricted stock units issued to a member of the board of directors. Additionally, 183,824 warrants were issued to a former member of the board of directors in exchange for the return and cancellation of 125,000 shares of our common stock.

The impact on our results of operations for recording stock-based compensation for the three and six months ended June 30, 2011 and 2010 is as follows:
