9. Leases

We account for leases in accordance with ASC Topic 842: Leases.

We enter into lease agreements for the use of real estate space and certain other equipment under operating leases and we have no financing leases. Our leases are included in Right of use assets and Lease liabilities in our Condensed Consolidated Balance Sheet. Our leases have remaining lease terms of one year to seven years, some of which include options to extend. The majority of our leases with options to extend provide for extensions of up to five years with the ability to terminate the lease within one year. Our right of use asset and lease liability was higher on March 31, 2020 compared to December 31, 2019, million, respectively due to the extension of one of our leases. On February 28, 2020, we entered into an amendment to extend the lease on our facility in Ithaca, New York which resulted in recording an additional right of use asset and lease liability of $1.5 million. The lease, which was last amended on January 14, 2016, was scheduled to expire on May 31, 2021. The lease amendment provides for an extension of the lease for four additional years from June 1, 2021 to May 31, 2025. Lease expense is recognized on a straight-line basis over the lease term.

Operating lease expense for the three months ending March 31, 2020 and December 31, 2019 was $251 thousand and $237 thousand, respectively, and was included within Cost of sales, Engineering, design and product development expense, Selling and marketing expense, and General and administrative expense. Operating costs include short-term lease costs which were immaterial during the period.
