Subsequent Events [Abstract]
SUBSEQUENT EVENTS	18. SUBSEQUENT EVENTS We have adopted the disclosure provisions of Codification Topic 855-10-50-1, Subsequent Events, which provides guidance to establish general standards of accounting for and disclosures of events that occur after the balance sheet date but before financial statements are issued. Entities are required to disclose the date through which subsequent events were evaluated as well as the rationale for why that date was selected. This disclosure should alert all users of financial statements that an entity has not evaluated subsequent events after that date in the set of financial statements being presented. Codification Topic 855-10-50-1 requires additional disclosures only, and therefore did not have an impact on our financial condition, results of operations, earnings per share or cash flows. Public entities must evaluate subsequent events through the date that financial statements are issued. Accordingly, we have evaluated subsequent events through the time of filing on March 25, 2016, the date we have issued this Annual Report on Form 10-K. On January 4, 2016, we acquired certain business assets from DAY 1™ Technology, LLC of Minnesota. The acquired rights and know-how are primarily related to formulating our bovine antibodies into a gel solution for oral delivery to newborn calves via a syringe (or “tube”). This product format offers customers an alternative delivery option to the bolus (the standard delivery format of the bivalent First Defense^®product since first USDA approval and product launch in 1991) and could allow more significant penetration into the beef market. The formulation was developed by DAY 1™ Technology for us and has been sold as a feed product without disease claims since 2012. This purchase also includes certain other related private-label products that could generate approximately $300,000 in annual sales. The estimated fair values of the assets purchased in this transaction included inventory of $113,000, machinery and equipment of $132,000 in addition to certain intellectual property intangibles. The total purchase price was approximately $534,000. Approximately $368,000 of this amount was paid as of the closing date, and the remaining balance will be paid upon successful technology transfer and as a royalty on related product sales made through December 31, 2018. The impact of the acquisition on our proforma prior year operations is not significant. On February 3, 2016, we sold 1,123,810 shares of common stock at a price to the public of $5.25 per share in an underwritten public offering raising gross proceeds of approximately $5,900,000. The net proceeds, (after deducting underwriting discounts and other expenses related to the issuance) of approximately $5,323,000 will be used to construct and equip a facility that will produce Nisin, the active ingredient in Mast Out^®. During January 2016, we signed a commitment letter covering certain credit facilities with TD Bank N.A. aggregating approximately $4.3 million comprised of: (a) a $3.3 million construction loan, drawable over an 18-month period at up to 80% of the cost of equipment installed in the to be constructed commercial-scale production facility for Mast Out^®, during which interest only will be payable at a variable rate equal to the 30-day LIBOR plus 2.25%, which converts to a seven-year term loan facility at the end of construction at the same interest rate with monthly principal and interest payments based on a seven-year amortization schedule and (b) a $1.0 million construction loan, drawable over a 12-month period at up to 75% of the appraised value of the to be constructed commercial-scale production facility for Mast Out^®, during which interest only will be payable at a variable rate equal to the 30-day LIBOR plus 2.25%, which converts to a nine-year term loan facility at the end of construction at the same interest rate with monthly principal and interest payments based on a twenty-year amortization schedule. On March 11, 2016 we signed a revised commitment letter decreasing the equipment loan component to $2.5 million and increasing the mortgage component to $2.0 million. These credit facilities are subject to customary closing conditions and certain financial covenants. During the first quarter of 2016, we paid $20,500 for an option to purchase additional land nearby to our Portland facility that could be used to construct an 8,000 square foot building should we decide to exercise the option before the end of 2016 for an additional $184,500.
