CASH FLOW INFORMATION

We consider all highly liquid investments with a maturity of three months or less as of the date of purchase to be cash equivalents unless the investments are legally or contractually restricted for more than three months. We had non-cash investing and financing activities primarily related to increases in property acquired under capital leases of $18.1 million for the nine months ended September 30, 2015, and $11.6 million for the nine months ended September 30, 2014. We also had accrued purchases of property and equipment of $16.5 million at September 30, 2015 and $15.7 million at September 30, 2014. The effect of non-cash transactions is excluded from the accompanying Unaudited Condensed Consolidated Statements of Cash Flows.

We made interest payments, including interest on vehicle inventory financing, of $101.0 million during the nine months ended September 30, 2015, and $99.7 million during the nine months ended September 30, 2014. We made income tax payments, net of income tax refunds, of $218.1 million during the nine months ended September 30, 2015, and $180.4 million during the nine months ended September 30, 2014.
