[1] In conjunction with the adoption of ASC 842 the Company established a right-of-use asset of $3.1 million on January 1, 2019. For more information, please refer to Note

[2] Lease payments include options to extend lease terms that are reasonably certain of being exercised.

[3] Our leases do not provide a readily determinable implicit rate. Therefore, we must estimate our discount rate for such leases to determine the present value of lease payments at the lease commencement date. There were no legally binding minimum lease payments for leases signed but not yet commenced at March 31, 2019.

[4] The weighted average remaining lease term and weighted average discount rate used in calculating our lease liabilities were 2.2 years and 5.2%, respectively at March 31, 2019.
