The Company maintains cash balances in several financial institutions that are insured by either the Federal Deposit Insurance Corporation or the National Credit Union Association up to certain federal limitations. At times, the Company’s cash balance exceeds these federal limitations and it maintains significant cash on hand at certain of its locations. The Company has not historically experienced any material loss from carrying cash on hand. The amount in excess of insured limitations was $2.64 million and $4.83 million as of March 31, 2019 and December 31, 2018, respectively.

The Company provides credit in the normal course of business to customers located throughout the U.S. The Company performs ongoing credit evaluations of its customers and maintains allowances for doubtful accounts based on factors surrounding the credit risk of specific customers, historical trends, and other information. There were no customers that comprised more than 10.0% of the Company’s revenue for the three months ended March 31, 2019 and 2018.

The Company sources cannabis products for retail, cultivation and production from various vendors. However, as a result of regulations in the State of California, the Company’s California retail, cultivation and production operations must use vendors licensed by the State. As a result, the Company is dependent upon the licensed vendors in California to supply products. If the Company is unable to enter into a relationship with sufficient members of properly licensed vendors, the Company's sales may be impacted. During the three months ended March 31, 2019, we did not have any concentration of vendors for inventory purchases. However, this may change depending on the number of vendors who receive appropriate licenses to operate in the State of California.
