These policies include an evaluation of potential counterparties’ financial condition and an assignment of credit limits. These credit limits are established based on risk and return considerations under terms customarily available in the industry. We grant credit to utility customers and counterparties, substantially all of whom are located in our service territory, which covers most of Southern California and a portion of central California for SoCalGas, and all of San Diego County and an adjacent portion of Orange County for SDG&E. We also grant credit to utility customers and counterparties of our other companies providing natural gas or electric services in Mexico, Chile and Peru.</font></div><div style="line-height:125%;padding-bottom:8px;padding-top:0px;padding-left:0px;text-indent:0px;font-size:10pt;"><font style="font-family:Times New Roman;font-size:10pt;color:#000000;">As they become operational, projects owned or partially owned by Sempra LNG & Midstream, Sempra Renewables, Sempra South American Utilities and Sempra Mexico place significant reliance on the ability of their suppliers, customers and partners to perform under long-term agreements and on our ability to enforce contract terms in the event of nonperformance. We consider many factors, including the negotiation of supplier and customer agreements, when we evaluate and approve development projects.</font></div></div> | |

Although we believe the estimates and assumptions are reasonable, actual amounts ultimately may differ significantly from those estimates.</font></div></div> |
