Leases

9 Months Ended

Sep. 30, 2019

In February 2016, the FASB issued ASC 842, which outlines a comprehensive change to the lease accounting model

and supersedes prior lease guidance ("ASC 840"). The new guidance requires lessees to recognize lease liabilities and corresponding right-of-use assets for all leases with lease terms of greater than 12 months, and also changes the definition of a lease and expands the disclosure requirements of lease arrangements.

The Company adopted this guidance on January 1, 2019 using the modified retrospective transition effective date method. As part of that adoption, we have elected the package of three practical expedients, which includes the following: an entity may elect not to reassess whether expired or existing contracts contain a lease under the revised definition of a lease; an entity may elect not to reassess the lease classification for expired or existing leases; and an entity may elect not to reassess whether previously capitalized initial direct costs would qualify for capitalization. The Company has elected not to utilize the hindsight expedient in determining the lease term, and to not record leases with an initial term of 12 months or less on our balance sheet. Additionally, the Company has elected to account for lease components and non-lease components as a single lease component for all asset classes. Lease expense is recognized over the expected term on a straight-line basis. The adoption did not have a material impact on the Company's condensed consolidated statements of income or cash flows.

The Company enters into operating leases primarily for real estate to support research and development ("R&D") sites and general office space in North America, with additional locations in Europe and Asia. The Company does not currently have any finance leases. Certain of our leases include options to extend the lease at our discretion at the end of the lease term, or terminate the lease early subject to certain conditions and penalties. We do not include any renewal options in our lease terms for calculating our lease liabilities, as the renewal options allow us to maintain operational flexibility and we are not reasonably certain we will exercise these options.

At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the specific facts and circumstances present. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected lease term. The interest rate implicit in lease contracts is typically not readily determinable, and, as such, the Company utilizes its incremental borrowing rate as the discount rate based on information available on the lease commencement date. Our incremental borrowing rate represents the rate we would incur to borrow on a collateralized basis over a similar term for an amount equal to the lease payments in a similar economic environment. We utilized the incremental borrowing rate as of January 1, 2019, our adoption date, for operating leases that commenced prior to that date. Upon our adoption of ASU 2016-02, the Company recorded the following operating lease right-of-use assets and operating lease liabilities as of January 1, 2019. Additionally, the table below includes the balances of operating lease right-of-use assets and operating lease liabilities as of September 30, 2019 (in thousands):

For the three and nine months ended September 30, 2019, sublease income was insignificant. Cash paid for amounts included in the measurement of operating lease liabilities for the three and nine months ended September 30, 2019 was $1.4 million and $3.8 million, respectively, and was included in net cash provided by operating activities in our condensed consolidated statements of cash flows. Operating lease right-of-use assets obtained in exchange for operating lease obligations

totaled $5.5 million during the three and nine months ended September 30, 2019. As of September 30, 2019, the weighted average remaining operating lease term was 5.6 years and the weighted average discount rate used to determine the operating lease liabilities was 6.2%. As of September 30, 2019, the Company had an additional operating lease that had not yet commenced of approximately $10.0 million, which is set to commence in October 2019 and will have a lease term of approximately 10.8 years years.
