Most contracts require payments as the projects progress or, in certain cases, advance payments. The company generally does not require collateral, but in most cases can place liens against the property, plant or equipment constructed or terminate the contract, if a material default occurs. The company evaluates the counterparty credit risk of third parties as part of its project risk review process and in determining the appropriate level of reserves. The company maintains adequate reserves for potential credit losses and generally such losses have been minimal and within management's estimates. However, in the third quarter of 2010, the company recognized a pre-tax charge of $95 million related to a bankruptcy court ruling that adversely impacted the collectability of amounts due the company on a completed infrastructure joint venture project in California. In 2011, $11 million of this amount was recovered in a settlement with the bankrupt client.</font></p> <p style="FONT-FAMILY: times; TEXT-ALIGN: justify"><font size="2">        Cash and marketable securities are deposited with major banks throughout the world. Such deposits are placed with high quality institutions and the amounts invested in any single institution are limited to the extent possible in order to minimize concentration of counterparty credit risk. The company has not incurred any credit risk losses related to these deposits.</font></p> <p style="FONT-FAMILY: times; TEXT-ALIGN: justify"><font size="2">        The company's counterparties for derivative contracts are large financial institutions selected based on profitability, strength of balance sheet, credit ratings and capacity for timely payment of financial commitments, which are unlikely to be adversely affected by foreseeable events. There are no significant concentrations of credit risk with any individual counterparty related to our derivative contracts.</font></p> <p style="FONT-FAMILY: times; TEXT-ALIGN: justify"><font size="2">        The company monitors credit risk by continuously assessing the credit quality of its counterparties.</font></p></div>
