Credit Facilities

In June 2013, MEHC terminated its $479 million revolving credit facility expiring in July 2013.

In March 2013, PacifiCorp replaced its $630 million unsecured revolving credit facility, which had been set to expire in July 2013 with a $600 million unsecured revolving credit facility expiring in March 2018. The new credit facility, which supports PacifiCorp's commercial paper program, certain series of its tax-exempt bond obligations and provides for the issuance of letters of credit, has a variable interest rate based on the London Interbank Offered Rate ("LIBOR") or a base rate, at PacifiCorp's option, plus a spread that varies based on PacifiCorp's credit ratings for its senior unsecured long-term debt securities. As of June 30, 2013, PacifiCorp had no borrowings outstanding under this credit facility. The credit facility requires that PacifiCorp's ratio of consolidated debt, including current maturities, to total capitalization not exceed 0.65 to 1.0 as of the last day of each quarter. As of June 30, 2013, $270 million of letters of credit were issued under this credit agreement to support variable-rate tax-exempt bond obligations. These letters of credit were previously issued under the credit facility that was replaced.

In March 2013, PacifiCorp obtained $289 million of letters of credit to support variable-rate tax-exempt bond obligations. These letters of credit expire through March 2015 and replaced certain letters of credit previously issued under one of the revolving credit facilities.

As of December 31, 2012, PacifiCorp had $68 million of tax-exempt bond obligations with fixed interest rates, ranging from 3.90% to 4.13%, scheduled to reset to variable or fixed interest rates in June 2013. In June 2013, $17 million of these tax-exempt bond obligations were redeemed and retired prior to their scheduled 2014 maturity date. The interest rates for the remaining $51 million, with maturity dates ranging from 2014 to 2025, were reset to variable interest rates with a weighted average interest rate of 0.25% as of June 30, 2013.
