On October 29, 2012, our Board of Directors approved a $650 million restructuring, related implementation and spin-off transition program (“Restructuring Program”) reflecting primarily severance, asset disposals, other manufacturing-related one-time costs and professional service fees within our finance, legal and information systems functions. The Restructuring Program is part of, and its costs are consistent with, a restructuring program previously announced by our former parent company, Mondelēz International, Inc., prior to our spin-off from Mondelēz International on October 1, 2012. The primary objective of the Restructuring Program activities is to ensure that we are set up to operate efficiently and execute our business strategy as a stand-alone company. Approximately one-half of the total Restructuring Program costs are expected to result in cash expenditures. In addition to approving the Restructuring Program, our Board approved related capital expenditures of $200 million. We expect to complete the Restructuring Program by the end of 2014.

This Item 2.05 contains a number of forward-looking statements. Words, and variations of words, such as “expect,” “intend,” “plan,” “believe,” “will,” and similar expressions are intended to identify our forward-looking statements, including but not limited to, those related to our expected costs, the Restructuring Program and capital expenditures. These forward-looking statements involve risks and uncertainties, many of which are beyond our control, and important factors that could cause actual results to differ materially from those indicated in the forward-looking statements include, but are not limited to, increased competition; continued consumer weakness and weakness in economic conditions; continued volatility and increases in commodity and other input costs; pricing actions; tax law changes; our ability to achieve the benefits we expect to achieve from the spin-off and to do so in a timely and cost-effective manner; and our lack of operating history as an independent, publicly traded company. For additional information on these and other factors that could affect our forward-looking statements, see our risk factors, as they may be amended from time to time, set forth in our filings with the SEC, including our Registration Statement on Form 10. We disclaim and do not undertake any obligation to update or revise any forward-looking statement in this Item 2.05, except as required by applicable law or regulation.
