[1] During the fourth quarter of 2011, the Company corrected an immaterial error in its consolidated financial statements. The error related to accounting for operating leases. The correction of $6,035 resulted in an additional charge to selling, general and administrative expense in the Company’s 2011 fourth quarter consolidated statement of operations. The Company believes the correction of this error to be both quantitatively and qualitatively immaterial to its quarterly results for 2011 or to any of its previously issued consolidated financial statements. The correction had no impact on the Company’s cash flows as previously presented.

[2] Amount represents the adjustment to fair value of a redeemable noncontrolling interest in a consolidated subsidiary of the Company.
