Debt and Credit Facilities | DEBT AND CREDIT FACILITIES LINES OF CREDIT On January 17, 2018, pursuant to the terms of the Sempra Energy and Sempra Global credit facilities, the amounts available under the lines of credit were increased by $250 million, from $1.0 billion to $1.25 billion, for Sempra Energy and by $850 million, from $2.335 billion to $3.185 billion, for Sempra Global. At March 31, 2018, Sempra Energy Consolidated had an aggregate of approximately $5.4 billion in three primary committed lines of credit for Sempra Energy, Sempra Global and the California Utilities to provide liquidity and to support commercial paper. The principal terms of these committed lines of credit, which expire in October 2020, are described below and in Note 5 of the Notes to Consolidated Financial Statements in the Annual Report. Available unused credit on these lines at March 31, 2018 was approximately $2.2 billion. Our foreign operations have additional general purpose credit facilities aggregating $1.7 billion, with $1.3 billion available unused credit at March 31, 2018.

Sempra Energy, SDG&E and SoCalGas must maintain a ratio of indebtedness to total capitalization (as defined in each of the applicable credit facilities) of no more than 65 percent at the end of each quarter.
