Based on management’s evaluation, the total amount of unrecognized tax benefits related to research and development credits as of March 31, 2020 and 2019 was $2.3 million and $2.4 million, respectively. There were no interest or penalties related to unrecognized tax benefits as of March 31, 2020 or March 31, 2019.

The fully reserved recognized federal and state deferred tax assets related to research and development credits balance as of March 31, 2020 and 2019 was $7.6 million and $8.4 million, and $9.7 million and $9.0 million, respectively.
