Note 9 - Concentration Risk

Cash and cash equivalents.

We maintain deposits in banks in amounts that might exceed the federal deposit insurance available. Management believes the potential risk of loss on these cash and cash equivalents to be minimal. All cash balances as of March 31, 2020 and December 31, 2019, including foreign subsidiaries, without FDIC coverage were $0.6 million and $2.5 million, respectively.

Revenue

A significant portion of our revenue was derived from the Rich Dad brands. For the three months ended March 31, 2020 and 2019, Rich Dad brands provided 69.6% and 84.3% of our revenue. In addition, we have operations in North America, United Kingdom and Other foreign markets (see Note 10 — Segment Information).
