Other Liabilities Disclosure [Abstract]
DERIVATIVE LIABILITIES	DERIVATIVE LIABILITIES As discussed further in Note 14 - Private Placement Investment, in conjunction with the 2012 private placement investment, the Company issued common stock warrants exercisable for up to 1,200,000 of common stock at an exercise price of $3.99 per share. The warrants were initially classified in stockholders' equity as additional paid-in capital at the allocated amount, net of allocated transaction costs, of $1,425,000. Effective October 31, 2012, upon stockholder approval of anti-dilution provisions that reset the warrant's exercise price if a dilutive issuance occurs, the warrants were reclassified as non-current derivative liabilities. The fair value of the warrants was $4,139,000 at October 31, 2012, with the difference between the fair value and carrying value recorded to additional paid-in capital. Effective as of the reclassification as derivative liabilities, the warrants are re-valued at each reporting date, with changes in fair value recognized in earnings each reporting period as a credit or charge to miscellaneous income (expense). The fair value of the warrants at January 31, 2016 and 2015 was $205,000 and $1,834,000, respectively. The change in fiscal 2015 and 2014 reflects $1,629,000 and $2,283,000, respectively, of miscellaneous income recognized in the consolidated statements of operations as a result of decreases in the fair value of the warrants. The estimated fair value of the warrant liabilities as of January 31, 2016 was computed using the Black-Scholes option pricing model based on the following assumptions: annual volatility of 60.1%; risk-free rate of 0.6%, dividend yield of 0.0% and expected life of two years. The estimated fair value of the warrant liabilities as of January 31, 2015 was computed using Monte-Carlo simulations based on the following assumptions: annual volatility of 55%; risk-free rate of 0.8%, dividend yield of 0.0% and expected life of three years.
