Supplemental Balance Sheet Information	Note 5 — Supplemental Balance Sheet Information Additional supplemental balance sheet information is provided as follows: As of March 31, 2020, approximately $16.0 million of the $18.6 million of cash is restricted. Other current assets of $0.6 million as of March 31, 2020 include $0.5 million for a tax refund to be received in 2020. Total assets of as of March 31, 2020 include a $14.8 million investment in Arrive LLC (“Arrive”). Historically, we accounted for such investments under the cost method of accounting. The adoption of ASU No. 2016-01 in the first quarter of 2018 effectively eliminated the cost method of accounting, and the carrying value of this investment is written down, or impaired, to fair value when a decline in value is considered to be other-than-temporary. Our strategic investment in equity securities does not have a readily determinable fair value; therefore, the new guidance was adopted prospectively. As of March 31, 2020, there were no indicators of impairment for this investment. The Company will assess the investment for potential impairment, quarterly. Other assets of $1.8 million as of March 31, 2020 include a $0.6 million minimum tax credit.
