The fair value of our investment in CyrusOne was based on the closing market price of CyrusOne's common stock on March 31, 2013. This fair value measurement is considered Level 1 of the fair value hierarchy.

The fair value of our long-term debt was based on closing or estimated market prices of the Company’s debt at March 31, 2013 and December 31, 2012, which is considered Level 2 of the fair value hierarchy.

On January 24, 2013, upon completion of the IPO of CyrusOne, we removed CyrusOne's other financing arrangements from our consolidated financial statements. As of December 31, 2012, the fair value of other financing arrangements was calculated using a discounted cash flow model that incorporates current borrowing rates for obligations of similar duration, which is considered Level 3 of the fair value hierarchy.
