Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies We are subject to legal proceedings and business disputes involving ordinary routine legal proceedings and claims incidental to our business. The ultimate legal and financial liability with respect to such matters generally cannot be estimated with certainty and requires the use of estimates in recording liabilities for potential litigation settlements or awards against us. Estimates for losses from litigation are made after consultation with outside counsel. If estimates of potential losses increase or the related facts and circumstances change in the future, we may be required to record either more or less litigation expense. We are not involved in any pending or threatened legal proceedings that we believe would reasonably be expected to have a material adverse effect on our financial condition, results of operations or cash flows.
