(b) The effective tax rates in 2011, 2010, 2009 and 2007 were impacted by the recording of $10.7 million, $10.5
million, $23.7 million and $34.4 million of tax benefits in each respective year primarily due to decreases in
reserves for uncertain tax positions resulting from the expiration of various federal and state statutes of
limitations.
(c) In the second quarter of 2010, we recorded a $7.1 million loss on early extinguishment of debt as a result of
the redemption of all of our outstanding 3.75% convertible subordinated notes due 2026 (3.75% Notes).
This loss includes a non-cash loss of $3.5 million related to the difference between the net carrying value
and the estimated fair value of the 3.75% Notes calculated as of the date of redemption, the payment of $2.3
million representing the 1.607% redemption premium above par value and a non-cash loss of $1.3 million
from the write-off of the remaining unamortized deferred financing costs related to the 3.75% Notes.
(d) On August 31, 2007, we sold the operating assets of Environmental Professional Associates, Limited, a
Quanta subsidiary. The historical results of operations associated with this business have been presented as a
