We maintain lease agreements principally for our office spaces and certain equipment. We maintain two sublease agreements with respect to one of our office locations, each of which continues through the initial term of our master lease agreement. Such sublease income and payments, while they reduce our rent expense, are not considered in the value of the right-of-use asset or lease liability. With the exception of two finance leases related to a network server and office equipment, all of our leases are classified as operating leases. In the aggregate, our leases generally have remaining lease terms of four to 30 months, some of which include options to extend the lease for additional periods. Such extension options were not considered in the value of the right-of-use asset or lease liability because it is not probable that we will exercise the options to extend. If applicable, allocations among lease and non-lease components would be achieved using relative standalone selling prices.
