Note

Operating

Leases

We lease office and manufacturing space and certain office equipment under noncancelable operating leases. We determine whether an arrangement is or contains a lease at its inception. We recognize lease liabilities based on the present value of the minimum lease payments

not

yet paid, by using the lease term and discount rate determined at lease commencement. As our leases do

not

provide an implicit rate, we use our incremental borrowing rate of

9.5%

commensurate with the underlying lease terms to determine the present value of our lease payments. Rental payments are recognized as rent expense on a straight-line basis over the term of the lease and for the

three

and

nine

months ended

September 30, 2019,

we recognized rent expense in the amount of

$0.6

million and

$1.7

million, respectively. Our leases have remaining lease terms of

one

year to

years,

one

of which includes an option to extend the lease for

five

years. For the

three

and

nine

months ended

September 30, 2019,

cash payments against operating lease liabilities totaled

$0.5

million and

$1.5

million, respectively.
