&lt;p style="MARGIN-TOP: 6px; MARGIN-BOTTOM: 0px"&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The effective tax rates were 50.6%
and 34.0% for the three months ended March&amp;#xA0;31, 2010 and 2009.
The increase in the effective tax rate as compared with the prior
year was primarily due to an income tax charge of $150 recorded
during the first quarter of 2010 as a result of the Patient
Protection and Affordable Care Act, as modified by the Health Care
and Education Reconciliation Act of 2010. As a result of this
legislation, beginning in 2013, we will no longer be able to claim
an income tax deduction related to prescription drug benefits
provided to retirees and reimbursed under the Medicare Part D
retiree drug subsidy. The increase in the effective tax rate was
also due to U.S. research and development tax credit benefits that
existed in 2009, but do not exist in 2010. The research and
development tax credit reduced the 2009 tax rate by 3.2% in the
first quarter of 2009.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The research and development credit
expired on December&amp;#xA0;31, 2009. Congress is currently
considering bills that will extend the credit. If the research and
development credit is legislatively extended there will be a
favorable impact on our 2010 effective income tax rate.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;The 1998-2009 tax years are subject
to examination by the Internal Revenue Service (IRS). We are also
subject to examination in major state and international
jurisdictions for the 2001-2009 tax years. We believe appropriate
provisions for all outstanding issues have been made for all
jurisdictions and all open years.&lt;/font&gt;&lt;/p&gt;
&lt;p style="MARGIN-TOP: 12px; MARGIN-BOTTOM: 0px"&gt;&lt;font style="FONT-FAMILY: ARIAL" size="2"&gt;Audit outcomes and the timing of
audit settlements are subject to significant uncertainty. It is
reasonably possible that within the next 12 months we will resolve
some or all of the matters presently under consideration for
1998-2006 with the IRS. Depending on the timing and outcomes of the
audit settlements, unrecognized tax benefits that affect the
effective tax rate could increase earnings by up to $650 based on
current estimates.&lt;/font&gt;&lt;/p&gt;
