COMMITMENTS AND CONTINGENCIES
NOTE 11. COMMITMENTS AND CONTINGENCIES
LITIGATION
     We are involved in litigation or proceedings that have arisen in our ordinary business activities. We insure against these risks to the extent deemed prudent by our management and to the extent insurance is available, but no assurance can be given that the nature and amount of that insurance will be sufficient to fully indemnify us against liabilities arising out of pending and future legal proceedings. Many of these insurance policies contain deductibles or self-insured retentions in amounts we deem prudent and for which we are responsible for payment. In determining the amount of self-insurance, it is our policy to self-insure those losses that are predictable, measurable and recurring in nature, such as claims for automobile liability, general liability and workers compensation. The accruals for losses are calculated by estimating losses for claims using historical claim data, specific loss development factors and other information as necessary.
     We were among several unrelated companies who received a subpoena from the Office of the New York Attorney General, dated June 17, 2011. The subpoena received by the Company seeks information and documents relating to, among other things, natural gas development and hydraulic fracturing. We are reviewing the subpoena and discussing its contents with the New York Attorney General’s office in anticipation of our responding as appropriate.
     In July 2011, the Company settled the previously reported customer claim against BJ Services relating to the move of a stimulation vessel out of the North Sea market. The settlement did not have a material effect on our consolidated condensed financial statements.
OTHER
     In the normal course of business with customers, vendors and others, we have entered into off-balance sheet arrangements, such as surety bonds for performance, letters of credit and other bank issued guarantees, which totaled approximately $1.2 billion at September 30, 2011. None of the off-balance sheet arrangements either has, or is likely to have, a material effect on our consolidated condensed financial statements.
