Commitments and Contingencies Disclosure [Abstract]

Contract Performance Contingencies [Policy Text Block]

Contract Performance Contingencies

Contract profit margins may include estimates of revenues not contractually agreed to between the customer and the company for matters such as settlements in the process of negotiation, contract changes, claims and requests for equitable adjustment for previously unanticipated contract costs.

Guarantees of Subsidiary Performance Obligations

Guarantees of Subsidiary Performance Obligations

From time to time, in the ordinary course of business, the company guarantees obligations of its subsidiaries under certain contracts. Generally, the company is liable under such an arrangement only if its subsidiary is unable to perform under its contract. Historically, the company has not incurred any substantial liabilities as a result of these guarantees.

In addition, the company’s subsidiaries may enter into joint ventures, teaming and other business arrangements (collectively, Business Arrangements) to support the company’s products and services in domestic and international markets. The company generally strives to limit its exposure under these arrangements to its subsidiary’s investment in the Business Arrangements, or to the extent of such subsidiary’s obligations under the applicable contract. In some cases, however, the company is required to guarantee the performance of the Business Arrangements and, in such cases, the company generally obtains cross-indemnification from the other members of the Business Arrangements.

U.S. Government Cost Claims

U.S. Government Cost Claims

From time to time, the company is advised of claims by the U.S. government concerning certain potential disallowed costs, plus, at times, penalties and interest. When such findings are presented, the company and the U.S. government representatives engage in discussions to enable the company to evaluate the merits of these claims, as well as to assess the amounts being claimed. Where appropriate, provisions are made to reflect the company’s expected exposure to the matters raised by the U.S. government. Such provisions are reviewed on a quarterly basis for sufficiency based on the most recent information available. The company believes that it has adequately reserved for any disputed amounts and that the outcome of any such matters would not have a material adverse effect on its consolidated financial position as of September 30, 2012, or its annual results of operations or cash flows.

Environmental Matters

Environmental Matters

The estimated cost to complete remediation has been accrued where the company believes, based on the facts and circumstances known to the company, that it is probable that the company will incur costs to address environmental impacts at currently or formerly owned or leased operating facilities, or at sites where it has been named a Potentially Responsible Party by the Environmental Protection Agency, or similarly designated by other environmental agencies.
