Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On April 1, 2013, our Convertible Senior Notes became convertible again. See Note 8—Debt for more information. In April 2013, Hertz entered into an Amendment No. 2, or "Amendment No. 2," to the Senior Term Facility, primarily to reduce the interest rate applicable to a portion of the outstanding term loans under the Senior Term Facility. Prior to Amendment No. 2, approximately $1,372.0 million of tranche B term loans, or “Tranche B Term Loans”, under the Senior Term Facility bore interest at a floating rate measured by reference to, at Hertz's option, either (i) an adjusted London inter-bank offered rate not less than 1.00 percent plus a borrowing margin of 2.75 percent per annum or (ii) an alternate base rate plus a borrowing margin of 1.75 percent per annum. Pursuant to Amendment No. 2, certain of the existing lenders under the Senior Term Facility converted their existing Tranche B Term Loans into a new tranche of tranche B-2 term loans, or the “Tranche B-2 Term Loans”, in an aggregate principal amount, along with new loans advanced by certain new lenders, of approximately $1,372.0 million. The proceeds of Tranche B-2 Term Loans advanced by the new lenders were used to prepay in full all of the Tranche B Term Loans that were not converted into Tranche B-2 Term Loans. The Tranche B-2 Term Loans bear interest at a floating rate measured by reference to, at Hertz's option, either (i) an adjusted London inter-bank offered rate not less than 0.75 percent plus a borrowing margin of 2.25 percent per annum or (ii) an alternate base rate plus a borrowing margin of 1.25 percent per annum. The terms and conditions of the new Tranche B-2 Term Loans with respect to maturity, collateral, and covenants are otherwise unchanged compared to the Tranche B Term Loans. On April 15, 2013, Hertz entered into definitive agreements with China Auto Rental Holdings, Inc., or “China Auto,” and related parties pursuant to which Hertz made a strategic investment in China Auto. China Auto is the largest car rental company in China. Pursuant to the transaction, Hertz invested cash and certain of its assets in China and received common stock and convertible notes in return. Upon the closing of the transaction which occurred on April 30, 2013, Hertz owns 10% of China Auto's ordinary shares and has a seat on China Auto's Board. Upon conversion of the notes, Hertz would have 18.64% on a fully diluted basis. This transaction will be accounted for under the equity method of accounting in accordance with GAAP.
