Liquidity risk is the risk that suitable sources of funding for the Group may not be available (funding liquidity risk), or that the Group is unable to sell its assets on the market place (asset liquidity risk), making it unable to meet its short-term finance requirements and settle obligations. Such a situation would negatively impact the Group's results as it would result in the Company incurring higher borrowing expenses to meet its obligations or under the worst of conditions the inability of the Company to continue as a going concern. Saipem manages liquidity risk by targeting a capital structure that guarantees a level of liquidity adequate for the Group's needs, optimising the opportunity cost of maintaining liquidity reserves and achieving an optimal profile in terms of maturity and composition of debt, in accordance with management plans and business objectives including prescribed limits in terms of maximum ratio of debt to total equity and minimum ratio of medium and long-term debt to total debt as well as fixed rate medium and long-term debt to total medium-long term debt. In spite of the significant deterioration of market conditions, which during the year led to credit expansion and strong pressure on spreads, Saipem believes it has access to sufficient funding and borrowing facilities to meet currently foreseeable requirements, thanks to a use of credit lines that is both flexible and targeted to meet business needs. The liquidity management policies used - which were being applied even before the worsening of the crisis - have the objective of ensuring both the availability of adequate funding to meet short-term requirements and obligations and a sufficient level of operating flexibility to fund Saipem's development plans, while maintaining an adequate finance structure in terms of debt composition and maturity. At June 30, 2009, Saipem maintained unused borrowing facilities of o1,392 million. These facilities were unde interest rates that reflected market conditions. Fees charged for unused facilities were not significant. The following tables show total contractual payments (including interest payments) and maturities on financial debt and payments and due dates for trade and other payables.
