Financial Instruments and Fair Value Measurements

Fair Value of Financial Instruments

The carrying values of the Company's financial instruments approximate the estimated fair values as of June 30, 2012 and December 31, 2011, except for the Company's debt and other financing arrangements.

The carrying value and fair value of the Company’s long-term debt and other financing arrangements are as follows:

	June 30, 2012				December 31, 2011
(dollars in millions)	Carrying Value		Fair Value		Carrying Value		Fair Value
Long-term debt, including current portion	$	2,552.2	$	2,547.7	$	2,533.6	$	2,460.5
Other financing arrangements	48.3		48.5		47.9		47.2

The fair value of debt instruments was based on closing or estimated market prices of the Company’s debt at June 30, 2012 and December 31, 2011, which is considered Level 2 of the fair value hierarchy. 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.

Non-Recurring Fair Value Measurements

Certain long-lived assets, intangibles, and goodwill are required to be measured at fair value on a non-recurring basis subsequent to their initial measurement. These non-recurring fair value measurements generally occur when evidence of impairment has occurred.

As of June 30, 2012, the following assets were measured at fair value:

			Fair Value Measurements Using
(dollars in millions)	June 30, 2012		Quoted Prices in Active Markets for Identical Assets (Level 1)		Significant Other Observable Inputs (Level 2)		Significant Unobservable Inputs (Level 3)		Impairment Losses
Customer relationship intangible	$	—	$	—	$	—	$	—	$	(4.3	)
Property	5.5		—		—		5.5		(8.7		)
Impairment losses									$	(13.0	)

In the second quarter of 2012, the customer relationship intangible obtained in the Gramtel acquisition was deemed impaired. The fair value of this asset was estimated at zero, resulting in an impairment loss of $4.3 million. The fair value of this asset was estimated by management using a third party valuation specialist. The fair value was estimated using the income approach, which discounted the expected future earnings attributable to the acquired customer contracts. This fair value measurement is considered a Level 3 measurement due to the significance of its unobservable inputs.

In addition, leasehold improvements and other property at two data centers were deemed impaired. Prior to recognizing the impairment, these assets had a net book value of $14.2 million as of June 30, 2012. The fair value of the assets was written down to the estimated fair value of $5.5 million, resulting in an impairment loss of $8.7 million. The fair value of these assets was estimated by management using a third party valuation specialist. Fair value was estimated using either a cost approach or the market approach. This fair value measurement is considered a Level 3 measurement due to the significance of its unobservable inputs.
