Here's something to put minimums into perspective-
Agreement with University of Arizona
Solterra entered into an exclusive Patent License Agreement with the University of Arizona (“UA”) in July 2009. On March 3, 2017, Solterra entered into an amended license agreement with UA. Pursuant to UA License Agreement, as amended, Solterra is obligated to pay minimum annual royalties of $50,000 by June 30, 2017, $125,000 by September 15, 2017 and $200,000 on each June 30th thereafter, subject to adjustments for increases in the consumer price index. Such minimum royalty payments shall be credited against royalties due in each respective royalty year, July 1 to June 30, following the due date. Royalties based on net sales are 2% of net sales of licensed products for non-display electronic component applications and 2.5% of net sales of licensed products for printed electronic displays. The UA License Agreements and subsequent amendments have been filed on Form 8-K and are incorporated by reference herein. The Company is in the process of renegotiating the minimum royalty commitments and while oral modifications have been agreed to a final amendment has not been finalized. As of March 31, 2019, no royalties have been accrued for this obligation.
