These factors include, among others, the inherent uncertainty associated with financial projections; restructuring in connection with, and successful close of the acquisition of Warner Chilcott; subsequent integration of the acquisition of Warner Chilcott and the ability to recognize the anticipated synergies and benefits of the acquisition; the receipt of required regulatory approvals for the acquisition of Warner Chilcott (including the approval of antitrust authorities necessary to complete the acquisition); the anticipated size of the markets and continued demand for Actavis' and Warner Chilcott's products; the impact of competitive products and pricing; access to available financing (including financing for the acquisition of Warner Chilcott) on a timely basis; maintaining a position in the Standard & Poor's 500; the risks of fluctuations in foreign currency exchange rates; the risks and uncertainties normally incident to the pharmaceutical industry, including product liability claims and the availability of product liability insurance on reasonable terms; the difficulty of predicting the timing or outcome of pending or future litigation or government investigations; periodic dependence on a small number of products for a material source of net revenue or income; variability of trade buying patterns; changes in generally accepted accounting principles; risks that the carrying values of assets may be negatively impacted by future events and circumstances; the timing and success of product launches; the difficulty of predicting the timing or outcome of product development efforts and regulatory agency approvals or actions, if any; market acceptance of and continued demand for Actavis' and Warner Chilcott's products; costs and efforts to defend or enforce intellectual property rights; difficulties or delays in manufacturing; the availability and pricing of third party sourced products and materials; successful compliance with governmental regulations applicable to Actavis' and Warner Chilcott's facilities, products and/or businesses; changes in the laws and regulations affecting, among other things, pricing and reimbursement of pharmaceutical products; changes in tax laws or interpretations that could increase Actavis' consolidated tax liabilities; the loss of key senior management or scientific staff; and such other risks and uncertainties detailed in Actavis' periodic public filings with the Securities and Exchange Commission, including but not limited to Actavis' Annual Report on form 10-K for the year ended December 31, 2012 and from time to time in Actavis' other investor communications.
