CASH AND CASH EQUIVALENTS

CASH AND CASH EQUIVALENTS

Short-term investments with an original maturity of three months or less are reported as cash equivalents.

The following is a supplemental disclosure to our statements of cash flows:

	Nine Months Ended September 30
(Millions)	2013			2012
Cash paid for interest	$	22.7		$	20.8
Cash received for income taxes	(2.4		)	(14.2		)

Cash received from income taxes decreased $11.8 million, primarily driven by refunds received in 2012 due to changes in estimated payments made for the prior year.

Construction costs funded through accounts payable totaled $29.5 million at September 30, 2013, and $15.8 million at September 30, 2012. These costs were treated as noncash investing activities.
