CERTIFICATION
I, Richard B. West, certify that:
(1) I have reviewed this quarterly report on
Form 10-Q
of Packaging Corporation of America (PCA);
(2) Based on my knowledge, this report does not contain any
untrue statement of a material fact or omit to state a material
fact necessary to make the statements made, in light of the
circumstances under which such statements were made, not
misleading with respect to the period covered by this report;
(3) Based on my knowledge, the financial statements, and
other financial information included in this report, fairly
present in all material respects the financial condition,
results of operations and cash flows of PCA as of, and for, the
periods presented in this report;
(4) PCAs other certifying officer and I are
responsible for establishing and maintaining disclosure controls
and procedures (as defined in Exchange Act
Rules 13a-15(e)
and
15d-15(e))
and internal control over financial reporting (as defined in
Exchange Act
Rules 13a-15(f)
and
15d-15(f))
for PCA and have:
a) designed such disclosure controls and procedures, or
caused such disclosure controls and procedures to be designed
under our supervision, to ensure that material information
relating to PCA, including its consolidated subsidiaries, is
made known to us by others within those entities, particularly
during the period in which this report is being prepared;
b) designed such internal control over financial reporting,
or caused such internal control over financial reporting to be
designed under our supervision, to provide reasonable assurance
regarding the reliability of financial reporting and the
preparation of financial statements for external purposes in
accordance with generally accepted accounting principles;
c) evaluated the effectiveness of PCAs disclosure
controls and procedures and presented in this report our
conclusions about the effectiveness of the disclosure controls
and procedures, as of the end of the period covered by this
report based on such evaluation; and
d) disclosed in this report any change in PCAs
internal control over financial reporting that occurred during
PCAs most recent fiscal quarter (PCAs fourth fiscal
quarter in the case of an annual report) that has materially
affected, or is reasonably likely to materially affect,
PCAs internal control over financial reporting; and
(5) PCAs other certifying officer and I have
disclosed, based on our most recent evaluation of internal
control over financial reporting, to PCAs auditors and the
Audit Committee of PCAs Board of Directors (or persons
performing the equivalent functions):
a) all significant deficiencies and material weaknesses in
the design or operation of internal control over financial
reporting which are reasonably likely to adversely affect
PCAs ability to record, process, summarize and report
financial information; and
b) any fraud, whether or not material, that involves
management or other employees who have a significant role in
PCAs internal control over financial reporting.
