<font style="FONT-FAMILY: Times New Roman" size="3">In June 2009,
the Financial Accounting Standards Board (FASB) amended its
accounting guidance on the consolidation of variable interest
entities (VIE). Among other things, the new guidance requires a
qualitative rather than a quantitative assessment to determine the
primary beneficiary of a VIE based on whether the entity
(1) has the power to direct matters that most significantly
impact the activities of the VIE and (2) has the obligation to
absorb losses or the right to receive benefits of the VIE that
could potentially be significant to the VIE. In addition, the
amended guidance requires an ongoing reconsideration of the primary
beneficiary. The provisions of this new guidance were effective as
of the beginning of our 2010 fiscal year, and the adoption did not
have a material impact on our financial statements.</font></p>

<font style="FONT-FAMILY: Times New Roman" size="3">In the second
quarter of 2010, the Patient Protection and Affordable Care Act
(PPACA) was signed into law. The PPACA changes the tax treatment
related to an existing retiree drug subsidy (RDS) available to
sponsors of retiree health benefit plans that provide a benefit
that is at least actuarially equivalent to the benefits under
Medicare Part D. As a result of the PPACA, RDS payments will
effectively become taxable in tax years beginning in 2013, by
requiring the amount of the subsidy received to be offset against
our deduction for health care expenses. The provisions of the PPACA
require us to record the effect of this tax law change beginning in
our second quarter of 2010, and consequently we expect to record a
one-time related tax charge of approximately $40 million in the
second quarter of 2010. We are currently evaluating the longer-term
impacts of this new legislation.</font></p>
