We have $25,017 of federal and $1,148 of state NOL carry forwards and $650 in research and development and other credits available to offset future taxable income. These federal and state NOLs will expire at various dates through 2034, except for federal NOLs generated in 2018 and subsequent years. Management analyzed its current operating results and future projections and determined that a full valuation allowance was needed due to our cumulative losses in recent years. We have no uncertain tax positions at December 31, 2020. Accordingly, we do not have any accruals for penalties or interest related to our tax returns. Should an examination or audit arise, we would evaluate the need for an accrual and record one, if necessary. Our federal tax returns from the tax years ended December 31, 2017 through December 31, 2019 are open to examination by the IRS.
