Revenue [Text Block]	NOTE 5 . Revenue Service Contracts with Customers Revenue Recognition. The Company recognized revenue of $94,000 from service contracts with customers of in the three months ended September 30, 2019 , the first period in which such revenue has been recorded. Revenue is recognized ratably as the Company provides promised services to its customers in amounts that reflect the consideration that the Company expects to receive for those services. Contract Balances. Accounts receivable related to service contracts with customers was $204,000 as of September 30, 2019. There were no such receivables as of December 31, 2018. There were no contract assets, representing unbilled receivables where revenue has been recognized in advance of customer billings, at either date. Remaining Performance Obligations. Remaining Performance Obligations (“RPO”) comprise deferred revenue plus unbilled contract revenue. As of September 30, 2019, the aggregate amount of RPO was $523,000, comprising $110,000 of deferred revenue, included in other accrued liabilities (see Note 4 ) and $413,000 of unbilled contract revenue which is not recorded on the balance sheet. We expect 100% of these amounts to be recognized as revenue within the next year. Unbilled contract revenue represents non-cancelable contracts under which the Company has an obligation to perform, for which and revenue has not yet been recognized in the financial statements and the fixed amounts billable have not yet been invoiced. Government Contract In September 2015, the Department of Health and Human Services, Office of Biomedical Advanced Research and Development Authority (“HHS BARDA”) awarded the Company a contract to support the advanced development of a more effective and universal influenza vaccine to improve seasonal and pandemic influenza preparedness. On each of May 25 and July 18, 2017, and June 28, 2018, the Company entered into a Modification of Contract with HHS BARDA, the combined effect being to increase the value of the existing $14 million contract by $1.7 million and to extend it through September 30, 2018. The modified contract was a cost-plus-fixed-fee contract, which reimbursed the Company for allowable direct contract costs plus allowable indirect costs and a fixed fee, totaling $15.7 million. The Company recognized revenue of $194,000 and $1,324,000 during the three and nine months ended September 30, 2018, respectively. As of December 31, 2018, the cumulative revenue recorded from inception under the HHS BARDA contract represented the maximum billable under the contract as presently modified, with no further change orders envisaged. Billings under the contract were based on approved provisional indirect billing rates, which permit recovery of fringe benefits, overhead and general and administrative expenses. Indirect rates as well as allowable costs are subject to audit by HHS BARDA on an annual basis. Management believes that revenues recognized to date have been recorded in amounts that are expected to be realized upon final audit and settlement. When the final determination of the allowable costs for any year has been made, revenue and billings may be adjusted accordingly in the period that the adjustments are known and collection is probable. Costs relating to contract acquisition are expensed as incurred. The Company does not consider any of the revenue recorded under this contract in any period to be at risk of reversal. Royalty Agreements Aviragen entered into a royalty-bearing research and license agreement with GlaxoSmithKline, plc (“GSK”) in 1990 for the development and commercialization of zanamivir, a neuraminidase inhibitor marketed by GSK under the name Relenza to treat influenza. All of the Company’s Relenza patents have expired, the last remaining intellectual property related to the Relenza patent portfolio, which is solely owned by the Company and exclusively licensed to GSK, having expired in July 2019 in Japan. The Company recognized royalty revenue related to Relenza of $8,000 in the three months ended September 30, 2019 compared to $87,000 in the three months ended September 30, 2018 . In the nine months ended September 30, 2019 , and in the post-Merger period in the nine months ended September 30, 2018 , the Company recognized royalty revenue related to Relenza of $772,000 and $498,000, respectively, representing 7% of net sales in Japan. The Company also generates royalty revenue from the sale of Inavir in Japan, pursuant to a collaboration and license agreement that Aviragen entered into with Daiichi Sankyo Company, Limited (“Daiichi Sankyo”) in 2009. In September 2010, laninamivir octanoate was approved for sale by the Japanese Ministry of Health and Welfare for the treatment of influenza in adults and children, which Daiichi Sankyo markets as Inavir. Under the agreement, the Company currently receives a 4% royalty on net sales of Inavir in Japan. The last patent related to Inavir is set to expire in December 2029, at which time royalty revenue will cease. The royalty revenue related to Inavir recognized in the nine months ended September 30, 2019 , and in the post-Merger period in the nine months ended September 30, 2018, was $2,964,000 and $552,000, respectively, representing 4% of net sales in Japan. No such revenue was recognized in the three months ended September 30, 2019 , since the sum receivable, net of withholding tax, of $335,000, was payable to Healthcare Royalty Partners III, L.P. (“HCRP”) (see Note 6 ). In the three months ended September 30, 2018 , no non-cash royalty revenue related to the sale of future royalties was earned. Both the royalty revenue and the non-cash royalty revenue related to the sale of future royalties have been subjected to a 5% withholding tax in Japan, for which $17,000 was included in income tax expense in the three months ended September 30, 2019 , and $254,000 and $29,000 was included in income tax expense in the nine months ended September 30, 2019 and 2018 , respectively. The Company’s royalty revenue is seasonal, in line with the flu season. The majority of the Company’s royalty revenue is earned in the first and fourth fiscal quarters.
