The Argentine economic decline and government responses (including Argentina's unilateral, retroactive abrogation of utility agreements early in 2002) continue to adversely affect the operations of these Argentine utilities. In 2002, Sempra Pipelines &amp;amp; Storage initiated arbitration proceedings at the International Center for the Settlement of Investment Disputes (ICSID) under the 1994 Bilateral Investment Treaty between the United States and Argentina for recovery of the diminution of the value of its investments that has resulted from Argentine governmental actions. In September 2007, the tribunal officially closed the arbitration proceedings and awarded us compensation of $172 million, which includes interest up to the award date. In January 2008, Argentina filed an action at the ICSID seeking to annul the award. In June 2010, the Annulment Committee granted Argentina's petition for annulment of the award. &lt;/font&gt;&lt;font style="font-family:Times New Roman;font-size:10pt;"&gt;This action did not impact our earnings, as we did not record the original award pending assurance of collectability. We are currently evaluating our options, which include filing a new arbitration claim against the Government of Argentina. &lt;/font&gt;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:6pt'&gt;&amp;#160;&lt;/p&gt;&lt;p style='margin-top:0pt; margin-bottom:0pt'&gt;&amp;#160;&lt;/p&gt;</NonNumbericText>
