The Company recorded stock-based compensation expense in the following categories on the accompanying consolidated statements of operations (in thousands):

	Fiscal Year Ended
	January 1, 2016		January 2, 2015		January 3, 2014

Research and development		466		938		659
Total stock-based compensation expense		3,304		4,663		4,489
Amounts capitalized as part of inventory		516		306		232
Total stock-based compensation	$	3,820	$	4,969	$	4,721

There was no net income tax benefit recognized in the consolidated statements of operations for stock-based compensation expense for non-qualified stock options, as the Company fully offsets net deferred tax assets with a valuation allowance (see Note 9). The Company does not recognize deferred income taxes for incentive stock option compensation expense, and records a tax deduction only when a disqualified disposition has occurred (see Note 9).

As of January 1, 2016, there was $6.8 million of total unrecognized compensation cost related to non-vested share-based compensation arrangements granted under the Plan ($4.7 million for stock options and $2.1 million for restricted stock and restricted stock units). That cost was expected to be recognized over a weighted-average period of approximately two years. On February 11, 2016, under the Restated Omnibus Equity Incentive Plan, a change in control occurred resulting in the immediate vesting of all unvested equity awards outstanding under the Plan (see Note 18).

Stock Option Plan

The Amended and Restated 2003 Omnibus Equity Incentive Plan (“the Plan”) provides for various forms of stock-based incentives. To date, of the available forms of awards under the Plan, the Company has granted only stock options, restricted stock, unrestricted share grants, and restricted stock units (RSUs). Options under the plan are granted at fair market value on the date of grant, become exercisable generally over a three year period, or as determined by the Board of Directors, and expire over periods not exceeding 10 years from the date of grant. Certain option and share awards provide for accelerated vesting if there is a change in control and pre-established financial metrics are met (as defined in the Plan) (see Note 18). Grants of restricted stock outstanding under the Plan generally vest over periods of one to three years. Grants of RSUs outstanding under the Plan generally vest based on service, performance or a combination of both. As of January 1, 2016, there were 1,072,776 shares authorized and available for grants under the Plan.

Assumptions

The fair value of each option award is estimated on the date of grant using a Black-Scholes option valuation model applying the weighted-average assumptions noted in the following table. Expected volatilities are based on historical volatility of the Company’s stock. The expected term of options granted is derived from the historical exercises and post-vesting cancellations, and represents the period of time that options granted are expected to be outstanding. The Company has calculated a 7% estimated forfeiture rate based on historical forfeiture experience. The risk-free rate is based on the U.S. Treasury yield curve corresponding to the expected term at the time of the grant.

	Fiscal Year Ended
	January 1, 2016			January 2, 2015			January 3, 2014
Expected dividend yield		0	%		0	%		0	%
Expected volatility		57	%		55	%		71	%
Risk-free interest rate		1.59	%		1.29	%		0.73	%
Expected term (in years)		5.57			4.12			4.12
