 Leases  
We have operating and finance leases for offices, terrestrial repeaters, data centers and certain equipment.  Our leases have remaining lease terms of less than 1 year to 18 years, some of which may include options to extend the leases for up to 5 years, and some of which may include options to terminate the leases within 1 year.  We elected the practical expedient to account for the lease and non-lease components as a single component.

The components of lease expense were as follows:
