Exhibit (a)(15)

General Employee Q&A

1. Can you explain today’s announcement?

These actions will strengthen the company’s ability to deliver future sustainable growth. These changes will enable us to further improve our global operations and efficiency to enhance our position as a leading global healthcare company.

2. How long have you been considering these changes?

With every acquisition and review of our strategy, we always look for opportunities to deliver additional shareholder value. And with our recent global acquisitions we now have the critical mass to effect changes that shared services constructs can address in a meaningful way.

3. Who and what business units will be impacted by today’s announcement?

Today Perrigo announced actions that will strengthen our ability to deliver future sustainable growth. These changes will enable us to further improve our global operations and efficiency to enhance our position as a leading global healthcare company. In summary, these actions will involve a number of strategic steps:

◦ Implementing a number of operational and cost efficiency measures;

◦ Refining our business portfolio, including commencing a sale process for the U.S. Vitamins, Minerals and Supplements (VMS) business;

◦ Undertaking initiatives to capture the benefits of the company’s global platform, consolidating and optimizing its global supply chain, procurement and research and development functions in Ireland; and

◦ Investing in our business by authorizing a $2 billion share repurchase plan.

As a result of these actions, we are confident that Perrigo will emerge from the Mylan tender offer period as a stronger company. Now is the time to take the next step in our strategy to leverage the powerful global platform we have built.

Further, we announced that John Hendrickson, formerly Executive Vice President, Global Operations and Supply Chain, will be promoted to the position of President, effective immediately, reporting to Perrigo Chairman and CEO Joseph Papa.

4. What are John Hendrickson’s new responsibilities?

John’s promotion will streamline the top tier of our organizational structure by allowing Chairman and CEO Joseph Papa to focus on the company’s overall strategy and executing on our M&A priorities. John will focus on the transformational matters of the company with the purpose of supporting the businesses outline in the press release. Details of the structure and specifics of the organization will be forthcoming.

5. Why are these initiatives being taken now?

We are confident that Perrigo will emerge from the Mylan tender offer period as a stronger company. Now is the time to take the next step in our strategy to leverage the powerful global platform we have built.

6. How were these business areas identified?

We have been studying and evaluating various forms of shared services for the last several years. With our recent global acquisitions we now have the critical mass to effect changes that shared services constructs can address in a meaningful way.

7. When will the company communicate further about organizational changes?

We plan to have additional information over the coming weeks.

8. Are you taking these actions because of Mylan’s bid for Perrigo?

We believe Mylan’s bid is a terrible deal for Perrigo. The initiatives we are announcing today demonstrate that we are not a static company, that we have and will continue to seize on opportunities to create a stronger, and better company for you and our shareholders.

9. What impact will this have on the Mylan tender offer?

To repeat: Mylan’s offer is a bad deal. Perrigo is better off on a standalone basis. These actions only make Perrigo stronger.

10. Will there be layoffs in the impacted business areas? How many people will be laid off?

In total, Perrigo will reduce its workforce by approximately 800 employees, or approximately 6 percent of its current global headcount. A large percentage of the 800 are employees of the soon to be divested U.S. Vitamins, Minerals and Supplement (VMS). The remainder will consist of open positions that will not be filled, and selected position eliminations across several areas of the organization.

11. Are there any alternatives to these layoffs?

The workforce reduction was one among a several options considered by the company. However, we are confident that the actions announced today will strengthen our ability to deliver future sustainable growth.
