The tax effects of temporary differences that give rise to significant portions of the deferred tax assets and liabilities at January 31, 2013 and 2012 are as follows (in thousands):
|  | January 31, |
|  | 2013 |  |  | 2012 |
Deferred tax assets: |  |  |  |  |  |
Inventory |  |  | 277 |  |  |  | 748 |
Property and equipment, principally due to differing depreciation methods |  |  | 206 |  |  |  | 671 |
Accruals and reserves |  |  | 184 |  |  |  | 300 |
Net research and manufacturer investment credit carryforwards |  |  | 2,563 |  |  |  | 2,576 |
Net operating losses |  |  | 14,322 |  |  |  | 11,894 |
AMT credit carryforwards |  |  | 126 |  |  |  | 126 |
Stock based compensation |  |  | 69 |  |  |  | 796 |
Other |  |  | 2 |  |  |  | 19 |
Total gross deferred tax assets |  |  | 17,749 |  |  |  | 17,130 |
Less: valuation allowance |  |  | (17,749 | ) |  |  | (17,130 | )
Net deferred tax assets |  | $ | — |  |  | $ | — |
We have federal and state research and experimentation credit carryforwards of $1.7 million and $2.1 million, respectively, which expire through 2032. We have a net operating loss carryforward of $37.6 million for federal and $36.2 million for state, which expire through 2032. Based upon a preliminary review, it appears that a Section 382 ownership change may have occurred during fiscal 2014. The effect of this ownership change may limit the utilization of our net operating loss carryforwards and research and experimentation credits to an annual amount of approximately $40,000. In assessing the probability that deferred tax assets will benefit future periods, management considers whether it is more likely than not that some portion or all of the deferred tax assets will not be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income. There was a full valuation allowance for deferred tax assets as of January 31, 2013, an increase of $0.6 million during the fiscal year, based on management’s overall assessment of risks and uncertainties related to our future ability to realize, and hence utilize, the deferred tax assets. A reconciliation of the beginning balance of our unrecognized tax benefits and the ending amount of unrecognized tax benefit is as follows (in thousands):
|  | Unrecognized Tax Benefits |
Balance at February 1, 2012 |  | $ | 760 |
Additions based on tax positions related to the current year |  |  | 17 |
Reductions due to lapses of statute of limitations |  |  | — |
Reductions for tax positions of prior years |  |  | — |
Balance at January 31, 2013 |  | $ | 777 |
The unrecognized tax benefits recorded above, if reversed, would not impact our effective tax rate since we maintain a full valuation allowance against our deferred tax asset. We recognize interest and penalties associated with unrecognized tax benefits in the income tax expense line item of the consolidated statement of operations. We and our subsidiary, CWT, file income tax returns in the U.S. federal jurisdiction and in certain state jurisdictions. With few exceptions, we are no longer subject to U.S. federal examinations or state income tax examinations by tax authorities for years before 2007 in those jurisdictions where returns have been filed.
