We have no financing leases and minimum annual rental commitments under non-cancellable operating leases consisted of the following at June 30, 2019 (in thousands):


Years Ending December 31,
2019 (a)	$	824
2020		1,450

2022		1,124
2023		777
Thereafter		1,840
Total lease payments (b)		7,328
Less: Interest (c)		1,195
Present value of lease liabilities (d)	$	6,133

(a)

Remaining payments are for the six-months ending December 31, 2019.

(b)

Lease payments include options to extend lease terms that are reasonably certain of being exercised. There were no legally binding minimum lease payments for leases signed but not yet commenced at June 30, 2019.

(c)

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.

The weighted average remaining lease term and weighted average discount rate used in calculating our lease liabilities were 6.9 years and 4.8%, respectively, at June 30, 2019.
