OUR LINES OF CREDIT

During September 2013, we entered into a new $1 billion 5-year senior unsecured revolving credit facility that expires in September 2018. This replaces a $1 billion revolving credit facility that was set to expire June 2015. As of June 16, 2014, WRECO terminated its participation as a borrower in the facility. There were no changes to our lines of credit during 2015.

Borrowings are at LIBOR plus a spread or at other interest rates mutually agreed upon between the borrower and the lending banks. As of December 31, 2015, there were no borrowings outstanding under the facility and we were in compliance with the credit facility covenants.

OTHER LETTERS OF CREDIT AND SURETY BONDS

The amounts of other letters of credit and surety bonds we have entered into as of the end of our last two years are included in the following table:

DOLLAR AMOUNTS IN MILLIONS
	DECEMBER 31, 2015		DECEMBER 31, 2014
Letters of credit	$	47	$	44
Surety bonds	$	113	$	231

Our compensating balance requirements for our letters of credit were $17 million as of December 31, 2015.
