Note 6-Warrant Liabilities

On August 26, 2016, Optex Systems Holdings, Inc. issued 4,323,135 warrants to new shareholders and the underwriter, in connection with a public share offering. The warrants entitle the holder to purchase one share of our common stock at an exercise price equal to $1.50 per share at any time on or after August 26, 2016 (the “Initial Exercise Date”) and on or prior to the close of business on August 26, 2021 (the “Termination Date”). The Company determined that these warrants are free standing financial instruments that are legally detachable and separately exercisable from the common stock included in the public share offering. Management also determined that the warrants are puttable for cash upon a fundamental transaction at the option of the holder and as such required classification as a liability pursuant to ASC 480 “Distinguishing Liabilities from Equity”. The Company has no plans to consummate a fundamental transaction and does not believe a fundamental transaction is likely to occur during the remaining term of the outstanding warrants. In accordance with the accounting guidance, the outstanding warrants are recognized as a warrant liability on the balance sheet and are measured at their inception date fair value and subsequently re-measured at each reporting period with changes being recorded as a component of other income in the statements of operations.

Beginning April 1, 2018 the Company reviewed the valuation technique and inputs used to determine the fair value of the outstanding warrants. For each of the prior period measurement dates through period ended December 31, 2017, the Company engaged an outside valuation company to calculate the fair value of warrants based on both the binomial lattice model (“Binomial”) and the Black Scholes-Merton option pricing model (“BSM”). For each of the periods previously presented through period ended December 31, 2017, the Company disclosed the valuation technique as binomial, although the two models yielded comparable results with minimal or no variation in the fair value calculation of the warrants at each of the respective measurement dates. As the BSM model yielded similar results with the Binomial model and can be completed with in-house expertise at a lower cost, effective as of April 1, 2018, the Company determined the BSM model will be used exclusively to value the outstanding warrants throughout the remaining term of the warrants.

The fair value of the warrant liabilities presented below were measured using either a BSM (July 1, 2018 through June 30, 2019) or Binomial (August 26, 2016 and October 1, 2017) valuation model. Significant inputs into the respective model at the inception and reporting period measurement dates are as follows:

(1) Based on the terms provided in the warrant agreement to purchase common stock of Optex Systems Holdings, Inc. dated August 26, 2016.

(2) Based on the trading value of common stock of Optex Systems Holdings, Inc. as of August 26, 2016 and each presented period ended date.

(3) Interest rate for U.S. Treasury Bonds, as of August 26, 2016 and each presented period ended date, as published by the U.S. Federal Reserve.

(4) Based on the historical daily volatility of Optex Systems Holdings, Inc. for the term of the warrants as of August 26, 2016 and October 1, 2017. The original fair value calculations were derived using the Binomial model, however, the yielded results were consistent with fair market valuation using the Black Scholes Merton Option Pricing model for each of the respective periods.

(5) Based on the historical daily volatility of Optex Systems Holdings, Inc. from the consummation of the public raise on August 26, 2016 through the current presented measurement date. As of the period ended July 1, 2018 and the year ended September 30, 2018, the company determined that the historical volatility prior to the August 26, 2016 public offering was not representative of the current market expectations due to the significant change in company capital structure and increase in public float shares (liquidity) arising from the common stock issued during the public offering and concurrent conversions of outstanding preferred shares into common stock and converted to an adjusted historical volatility calculated from the date of the public offering. The fair value calculation was derived using the Black Scholes Merton Option Pricing model. As of June 30, 2019, the historical volatility rate calculation period is consistent with the remaining term of the warrants.

The warrants outstanding and fair values at each of the respective valuation dates are summarized below:

During the three and nine months ended June 30, 2019 or July 1, 2018, 47,504 of the warrants were exercised and 88,081 were repurchased from the holders and cancelled. During the three and nine months ended June 30, 2019 and July 1, 2018, the Company recognized a ($81) thousand gain and a $465 thousand loss, respectively, and a ($4) thousand and ($2,010) thousand gain, respectively on the change in fair value of warrants, respectively.

The warrant liabilities are considered Level 3 liabilities on the fair value hierarchy as the determination of fair value includes various assumptions about future activities and the Company’s stock prices and historical volatility as inputs.
