|Income Tax Disclosure [Text Block]||
No provision for income taxes has been recorded due to the net operating losses incurred from inception to date, for which no benefit has been recorded.
A reconciliation of the U.S. statutory income tax rate to the Company’s effective tax rate is as follows:
The components of the Company’s net deferred tax assets and liabilities are as follows (in thousands):
The Company has recorded a full valuation allowance for its deferred tax assets based on it past losses and the uncertainty regarding the ability to project future taxable income. The valuation allowance increased by approximately
$4,822,000during the years ended
2016,the Company has net operating loss (“NOL”) carryforwards for federal and state income tax purposes of approximately
$24,498,000,respectively, which expire beginning in the year
The Company also has federal and California research and development tax credits of approximately
$454,000,respectively. The federal research credits will begin to expire in
2027and the California research and development credits have no expiration date.
Utilization of the NOL and research and development credit carryforwards
maybe subject to a substantial annual limitation due to ownership changes that have occurred previously or that could occur in the future, as provided by Section
382of the Internal Revenue Code of
1986,as well as similar state provisions. Ownership changes
maylimit the amount of NOL and tax credit carryforwards that can be utilized to offset future taxable income and tax, respectively. In general, an ownership change, as defined by Section
382,results from transactions increasing the ownership of certain shareholders or public groups in the stock of a corporation by more than
50percentage points over a
three-year period. If the Company has experienced a change of control, utilization of its NOL or tax credits carryforwards would be subject to an annual limitation under Section
mayresult in expiration of a portion of the NOL or research and development credit carryforwards before utilization. Subsequent ownership changes could further impact the limitation in future years. Until a Section
382study is completed and any limitation known, no amounts are being presented as an uncertain tax position. A full valuation allowance has been provided against the Company’s NOL carryforwards and research and development credit carryforwards and, if an adjustment is required, this adjustment would be offset by an adjustment to the valuation allowance. Thus, there would be no net impact to the balance sheet or statement of operations if an adjustment were required.

notaccrued any interest or penalties related to uncertain tax positions.

$268,000of unrecognized tax benefits as of
2016were recognized, none of the recognition would affect the income tax rate. The Company does not anticipate any material change in its unrecognized tax benefits over the next
twelvemonths. The unrecognized tax benefits
maychange during the next year for items that arise in the ordinary course of business.
The Company files U.S. federal and state income tax returns with varying statutes of limitations. All tax years since inception remain open to examination due to the carryover of unused net operating losses and tax credits.
