Leases [Abstract] |
Leases | 16. Leases The Company leases seismic equipment to customers under operating leases with non-cancelable terms of one year or less. These leases are generally renewable on a month-to-month basis. All taxes (other than income taxes) and assessments are the contractual responsibility of the lessee. To the extent that foreign taxes are not paid by the lessee, the relevant foreign taxing authorities might seek to collect such taxes from the Company. Under the terms of its lease agreements, any amounts paid by the Company to such foreign taxing authorities may be billed and collected from the lessee. If the Company is unable to collect the foreign taxes it paid on behalf of its lessees, the Company may have foreign tax credits in the amounts paid, which could be applied against its U.S. income tax liability subject to certain limitations. The Company is not aware of any foreign tax obligations as of January 31, 2013 and 2012 that are not reflected in the accompanying consolidated financial statements. The Company leases seismic equipment, as well as other equipment from others under operating leases. Lease expense incurred by the Company in connection with such leases amounted to approximately $1,798,000, $1,634,000 and $755,000 for the fiscal years ended January 31, 2013, 2012 and 2011, respectively. The Company leases its office and warehouse facilities in Canada, Australia, Singapore, United Kingdom and Russia under operating leases. Office rental expense for the fiscal years ended January 31, 2013, 2012 and 2011 was approximately $1,528,000, $1,199,000 and $1,007,000, respectively. Aggregate minimum lease payments for non-cancelable operating leases are as follows (in thousands):
