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

[2] Our leases do not provide a readily determinable implicit rate. Therefore, we utilized our incremental borrowing 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 December 31, 2019.

[3] In conjunction with the adoption of ASC 842, the Company established a $3.5 million lease liability on January 1, 2019. For more information, please refer to Note 1 and Note 11.

[4] The weighted average remaining lease term and weighted average incremental borrowing rate used in calculating our lease liabilities were 1.9 years and 4.4%, respectively, at December 31, 2019.
