Risks and Uncertainties [Abstract] |
Concentrations | 17. Concentrations Credit Risk—As of January 31, 2016 and 2015, amounts due from customers that exceeded 10% of consolidated accounts receivable amounted to an aggregate of approximately $11.6 million from four customers and $11.3 million from three customers, respectively. The Company maintains deposits and certificates of deposit with banks which may exceed the Federal Deposit Insurance Corporation (“FDIC”) insured limit and money market accounts which are not FDIC insured. In addition, deposits aggregating approximately $3.1 million at January 31, 2016 are held in foreign banks. Management believes the risk of loss in connection with these accounts is minimal. Industry Concentration— The majority of the Company’s revenues are derived from seismic equipment leased and sold to companies providing seismic acquisition services. The seismic industry has historically been subject to cyclical activity and is dependent, in large part, on the expected future prices of oil and natural gas. Should the industry experience a decline in the price of oil and natural gas, the Company could be subject to significantly greater credit risk and declining demand for its products and services. Supplier Concentration—The Company purchases the majority of its seismic equipment for its lease pool from a small number of suppliers, each being an industry leader for its product. The Company believes that two of its suppliers manufacture most of the land-based seismic systems and equipment in use. The Company has satisfactory relationships with its suppliers. However, should those relationships deteriorate, the Company may have difficulty in obtaining new technology requested by its customers and maintaining the existing equipment in accordance with manufacturers’ specifications.
