ITEM 2.02.  DISCLOSURE OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION
----------  -----------------------------------------------------------
On August 9, 2006, the Perrigo Company released earnings for the fourth quarter
and fiscal year 2006.

The earnings release contains non-GAAP measures which are defined as a financial
measure of the Company's performance that excludes or includes amounts thereby
differentiating it from the most directly comparable measure presented in the
financial statements that are calculated and presented in accordance with
Generally Accepted Accounting Principles (GAAP). Pursuant to the requirements of
Regulation G, the Company has provided a reconciliation for gross profit,
operating income, net income and earnings per share within its earnings release
to the most directly comparable GAAP measure for these non-GAAP measures.

The Company excludes the items listed below in the applicable fiscal year when
monitoring and evaluating the on-going financial results and trends of its
business due to the non-recurring nature of these items. The Company believes
this information is also useful for investors since excluding these
non-recurring items provides important insight into the Company's on-going
operations.

Items excluded from reported results:

     Fiscal 2006
     -----------
     -    A write-off of the step-up in value of inventory acquired
     -    A gain on the sale of an equity investment
     -    A restructuring charge for asset impairments

     Fiscal 2005
     -----------
     -    A write-off of the step-up in value of inventory acquired
     -    A lawsuit settlement charge
     -    A restructuring charge for organizational improvements and asset
          impairments
     -    A write-off of in-process research and development
     -    A charge for certain acquisition costs

The press release related to Perrigo's earnings is attached as Exhibit 99.

The information in this Report is being furnished and shall not be deemed
"filed" for the purposes of Section 18 of the Securities Exchange Act of 1934,
as amended, or otherwise subject to the liabilities of that Section. The
information in this Report shall not be deemed incorporated by reference into
any filing under the Securities Act of 1933, as amended, except as shall be
expressly set forth by specific reference in such filing.
