Leases [Abstract]

Leases

8. Leases

We have operating leases and subleases for office space, temporary housing, storage and shops. Our leases have remaining lease terms of less than 1 year to 11 years and most include options to extend the lease term, at our discretion, for an additional three to five years. We are not, however, reasonably certain that we will exercise any of the options to extend and as such, they have not been included in the remaining lease terms.
