("Senju"), due under the Exclusive License Agreement between the Company and Senju, as amended on April 8, 2020 and a Letter Agreement dated August 10, 2020 (the “Senju License Agreement”). The Company had recorded the $4.0 million payment as a deferred license fee until the payment is earned.

The trial data for one of the two products (MicroPine) was fully submitted to Arctic Vision by March 31, 2021. Therefore, one half of the upfront payment, or $2.0 million, has been earned. As a result, the Company will recognize $2.0 million of deferred license fees and recognize $0.8 million of deferred license costs related to the Senju payment as of March 31, 2021.
