Note 8 - Commitments and Contingencies	Note 8 – Commitments and Contingencies On September 18, 2017 GB Sciences finalized its agreement with Louisiana State University (“LSU”) AgCenter to be the sole operator of the LSU’s medical marijuana program. The LSU Board of Supervisors entered into a five-year agreement—that has an option to renew for two additional five-year terms—with GB Sciences. The contract includes the Company’s commitment to make a minimum financial contribution to the LSU AgCenter in the amount of $3.4 million, or a 10% commission of gross receipts, in addition to annual research investments of $500,000 to the LSU AgCenter. The $500,000 annual research investment is prepaid annually in September and amortized over a one-year period. The 10% commission on gross receipts will be accrued and paid as the sales are made. The Company’s first sales in Louisiana were made on August 6, 2019. The monetary contributions will be used to conduct research on plant varieties, compounds, extraction techniques and delivery methods that could generate additional revenue through discoveries that are subject to intellectual property rights, which AgCenter would retain 50% of those rights with the other 50% retained by the Company. As of June 30, 2019, GB Sciences has made payments totaling $1,600,000 toward its obligations under the agreement. For the three months ended June 30, 2019, the Company recorded $225,000 in expense related to the agreement. On December 6, 2018, the Company entered into an agreement with SylvaCap Media for business advisory and consulting services. In consideration for the services, the Company issued warrants to purchase 2 million shares of the Company’s common stock at $0.1125 per share. The Company valued the warrants at $244,000 using the Black-Scholes valuation model. The fair value of the warrants was recognized as consulting expense over the term of the agreement. The company recorded $162,667 in expense related to the warrants for the three months ended June 30, 2019. The Company also agreed to pay the consultant a $10,000 monthly fee for 12 months and to issue 4 million restricted shares of the Company’s common stock. The Company issued 2 million shares on the date of the contract, with the remaining 2 million due six months after the date of the agreement. On June 6, 2019, the Company entered into a Cancellation and Settlement with SylvaCap Media and terminated the December 6, 2018 agreement. In consideration for terminating the agreement, the Company will pay $135,000 as a one-time cancellation fee and will not issue the remaining 2 million shares due under the agreement. This amount is accrued in accounts payable as of June 30, 2019. During the year ended March 31, 2019, the Company recorded a $200,000 charge related to seizure of cash by local law enforcement during a routine traffic stop while transporting the cash to one of our subsidiaries. The charge was recorded in other expense as the Company believed it was more likely than not that the cash would not be returned. After appealing the seizure of the cash through the proper channels, the Company received a notice on July 15, 2019, that the government agency determined to return the cash to the Company. Accordingly, we anticipate receiving the $200,000 payment and will record it as other income when received. From time to time, the Company may become involved in certain legal proceedings and claims which arise in the ordinary course of business. In management’s opinion, based on consultations with outside counsel, the results of any of these ordinary course matters, individually and in the aggregate, are not expected to have a material effect on our results of operations, financial condition, or cash flows. As more information becomes available, if management should determine that an unfavorable outcome is probable on such a claim and that the amount of such probable loss that it will incur on that claim is reasonably estimable, the Company would record a reserve for the claim in question. If and when the Company records such a reserve, it could be material and could adversely impact its results of operations, financial condition, and cash flows.
