Risks And Uncertainties [Abstract] |
Concentrations of Credit Risk | 17. Concentrations of Credit Risk Financial instruments which potentially subject the Company to concentrations of credit risk consist primarily of demand deposits, temporary cash investments and trade receivables. The Company believes it has placed its demand deposits and temporary cash investments with high credit-quality financial institutions. At December 31, 2018 and 2017, the Company’s demand deposits and temporary cash investments consisted of the following (in thousands):
|  | 2018 |  |  | 2017 |
Deposits in FDIC and SIPC-insured institutions under insurance limits |  | $ | 191,457 |  |  | $ | 13,860 |
Deposits in FDIC and SIPC-insured institutions over insurance limits |  |  | 38,425 |  |  |  | 106,849 |
Deposits in foreign banks |  |  | 22,698 |  |  |  | 21,479 |
|  |  | 252,580 |  |  |  | 142,188 |
Less outstanding checks and other reconciling items |  |  | (7,551 | ) |  |  | (99,360 | )
Cash and cash equivalents |  | $ | 245,029 |  |  | $ | 42,828 |
Concentrations of credit risk with respect to trade receivables are primarily focused on companies involved in the exploration and development of oil and natural gas properties. The concentration is somewhat mitigated by the diversification of customers for which the Company provides services. As is general industry practice, the Company typically does not require customers to provide collateral. No significant losses from individual customers were experienced during the years ended December 31, 2018, 2017 or 2016. No expense for bad debts was recognized in 2018, 2017 or 2016.
