. LEASES
 
The Company has operating leases for administrative and sales and marketing offices, manufacturing operations and research and development facilities, employee housing units, and certain equipment. The leases have remaining lease terms from
one
to
four
years. Some of the leases include renewal options which can extend the lease term for up to
five
years or on a month-to-month basis. The Company does
not
have finance lease arrangements.
 
As permitted by Topic
842,
the Company does
not
recognize leases with a term of
12
months or less on the Condensed Consolidated Balance Sheets. For all lease arrangements that contain lease and nonlease components, the Company has elected the practical expedient to combine them as single lease components. As of
March 31, 2019,
operating lease ROU assets totaled
$2.8
million and operating lease liabilities totaled
$2.2
million. The Company recognizes operating lease costs on a straight-line basis over the lease term.
 
Because the implicit rate in each lease is
not
readily determinable, the Company uses its incremental borrowing rate to determine the present value of the remaining lease payments. 
 
The following tables summarize certain information related to the leases (in thousands, except years and percentages):
