14. Leases

The Company’s lease portfolio is comprised of operating leases for office space and equipment and finance leases for equipment. Equipment leases are comprised of vehicles and office equipment. The majority of the Company’s leases include both lease and non-lease components. Non-lease components primarily include maintenance, insurance, taxes and other utilities. The Company has decided to combine fixed payments for non-lease components with its lease payments and account for them as a single lease component, which increases its ROU assets and lease liabilities. Some of the leases include one or more options to renew or terminate the lease at the Company’s discretion. Generally, the renewal and termination options are not included in the ROU assets and lease liabilities as they are not reasonably certain of exercise. The Company has elected not to recognize a ROU asset or lease liability for leases with an initial term of 12 months or less.

As most of the Company’s leases do not provide an implicit rate, the Company uses its incremental borrowing rate based on the information available at commencement date in determining the present value of the future minimum lease payments. The Company applies the portfolio approach when determining the incremental borrowing rate since it has a centrally managed treasury function. The Company’s incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments in a similar economic environment.

Operating leases contain both office and equipment leases and have remaining terms that range from less than one year to 10 years, some of which also include options to extend or terminate the lease. Finance leases are comprised of equipment leases and have remaining terms that range from less than one year to 5 years. Finance lease assets are included in property and equipment, net while finance lease liabilities are included in other accrued liabilities and other liabilities.
