ITEM 2.02.    DISCLOSURE OF RESULTS OF OPERATIONS AND FINANCIAL CONDITION

On May 5, 2005, the Perrigo Company released earnings for the third quarter of
fiscal year 2005.

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 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 a write-off of in-process research and development,
restructuring costs, acquisition-related expenses, a product recall and a
one-time tax benefit 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.

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.
