Commitments And Contingencies Disclosure [Abstract]
Commitments and Contingencies	7. Commitments and Contingencies We are a party to various legal proceedings in the ordinary course of business. Although the ultimate disposition of these proceedings cannot be predicted with certainty, management believes the outcome of any claim that is pending or threatened, either individually or on a combined basis, will not have a material adverse effect on our consolidated financial position, cash flows or results of operations. However, there can be no assurances that future costs related to legal proceedings would not be material to our results of operations or liquidity for a particular period.
