Equity [Abstract]
Common Stock	Note 7 – Common Stock *Capital Stock* At June 30, 2018 and June 30, 2017, Aytu had 1,794,762 and 41,244 common shares outstanding, respectively, and no preferred shares outstanding. The Company has 100 million shares of common stock authorized with a par value of $0.0001 per share and 50 million shares of preferred stock authorized with a par value of $0.0001 per share, of which 500 were designated Series A Convertible Preferred Stock and 161 were designated as Series B Convertible Preferred Stock. Included in the common stock outstanding are 38,738 shares of restricted stock granted to executives, directors, employees and consultants. In July 2016, we entered into a purchase agreement (the “Purchase Agreement”), together with a registration rights agreement (the “Registration Rights Agreement”), with Lincoln Park Capital Fund, LLC (“Lincoln Park”). Upon signing the Purchase Agreement, Lincoln Park agreed to purchase 335 shares of our common stock for $500,000 as an initial purchase under the agreement. We also issued as a commitment fee to Lincoln Park of 131 shares of common stock. Between September 2016 and June 2017, Lincoln Park purchased an additional 500 shares for $240,000, the issuance costs related to these purchases totaled $91,000, resulting in net proceeds of $649,000. We terminated the Purchase Agreement effective August 16, 2017. In July 2016, we issued 2,500 shares of restricted stock as compensation to certain executive officers and directors, which vest in July 2026. This expense is included in sales, general and administrative. For the year ended June 30, 2017, the expense was $725,000. The original fair value of the restricted stock was $3.2 million. As of June 30, 2017, the remaining unrecognized expense is $2.5 million. During fiscal 2017, one of the Company’s executive officers resigned and his restricted stock vested in full upon this event. This resulted in the Company recognizing the remainder of the expense related to this executive’s restricted stock grant of $430,000. In August 2016, we issued an aggregate of 357 shares of common stock as bonuses for performance in 2016 to three executive officers. In November 2016, we raised gross proceeds of approximately $8.6 million through a public offering of 14,338 Units. Offering costs totaled $1.0 million resulting in net cash proceeds of $7.6 million. We also issued underwriter warrants in connection with the offering with a fair value of $293,000, resulting in net proceeds of $7.3 million. Each Unit consisted of one share of Aytu common stock and a warrant to purchase one share of Aytu common stock. The common stock issued had a relative fair value of $3.7 million and a fair value of $4.4 million. The investor warrants have an exercise price of $744.00 per share and will expire five years from the date of issuance. These investor warrants have a relative fair value of $3.5 million and a fair value of $4.2 million. We also granted the underwriters a 45-day option (the Over-Allotment Option) to purchase up to an additional 2,151 shares of common stock and/or warrants. The underwriters purchased 714 of this Over-Allotment Option for the warrants and paid $4.00 per over-allotment warrant. These warrants have the same terms as the warrants sold in the registered offering. These warrants have a relative fair value of $173,000, a fair value of $208,000, and proceeds of $3,000, which was the purchase price per the underwriting agreement. In February 2017, the Company consummated its warrant tender offer to exercise, at a temporarily reduced exercise price of $300.00 per share, (i) outstanding warrants to purchase 4,334 shares of common stock with an exercise price of $2,400.00 per share, which were originally issued to investors in the Company’s May 2016 financing (the “May 2016 Warrants”), and (ii) outstanding warrants to purchase 15,051 shares of common stock with an exercise price of $744.00 per share, which were originally issued to investors in the Company’s October 2016 financing (the “October 2016 Warrants” and together with the May 2016 Warrants, the “Original Warrants”). Original warrants to purchase an aggregate of 7,477 shares of common stock were tendered and exercised in the warrant tender offer, for aggregate gross proceeds to the Company of approximately $2.2 million. Original warrants that were not tendered and exercised remain in effect at the pre-tender offer exercise prices of $2,400.00 per share and $744.00 per share, respectively (see Note 11). In May 2017, we entered into a Merger Agreement with Nuelle, Inc. and its stockholders, pursuant to which Nuelle would become our wholly owned subsidiary (the “Merger”). The Merger closed on May 5, 2017. As part of the Merger, we issued to the Nuelle preferred stockholders an aggregate of 6,250 shares of our common stock. On August 11, 2017, we entered into a Securities Purchase Agreement with various accredited investors pursuant to which, upon closing on August 15, 2017, we sold Class A and Class B equity units for gross proceeds of approximately $11.8 million. Class A units consist of one (1) share of common stock and a warrant to purchase one and one-half (1.5) shares of common stock and were sold at a price of $60.00 per unit. Class B units consist of one (1) share of our newly created Series A Preferred Stock and warrants to purchase one and one-half (1.5) shares of common stock for each share of common stock into which the Series A Preferred Stock is convertible and were sold at a price of $20,000.00 per unit to those purchasers who, together with their affiliates and certain related parties, would beneficially own more than 9.99% of our outstanding common stock following the offering. These Series A Preferred stock were convertible into common shares at $60.00 per common share, or an aggregate of 37,500 shares of common stock. In the offering, we issued an aggregate of 159,834 shares of our common stock, 113 shares of Series A Preferred Stock and warrants to purchase up to an aggregate of 315,755 shares of our common stock, which included 19,749 warrants issued to the placement agents as compensation for the transaction. We incurred certain expenses related to this transaction to attorneys and underwriters inclusive of a 9% cash fee and warrants to purchase 10% of the aggregate number of shares issued in the transaction. In connection with the closing of the financing, we terminated the Purchase Agreement, dated as of July 27, 2016, by and between us and Lincoln Park Capital Fund, LLC. The termination was effective on August 16, 2017. In September 2017, Aytu issued 151 shares of common stock in connection with the Nuelle earn-out (see Note 1).
