[1] In 2012, the charges relate to the acquisition and integration of the Pinnacle business and Cooley business. The charges in the three months ended September 30, 2012 primarily consist of expenses incurred in connection with integrating these businesses into the Company's existing operational structure (e.g., accelerated depreciation, employee retention, information technology systems integration costs and other organizational streamlining expenses). The charges in the nine months ended September 30, 2012 impacting "Selling, general, and administrative expense" consist of: transaction-related expenses of $5 million, contract termination expenses of $10 million and integration related expenses of $1 million. Contract termination fees are primarily based on actual settlement agreements, but where a settlement agreement has not been reached, we recorded an estimated liability.

[2] In 2013, the gain (included in "Selling, general, and administrative expense") primarily relates to a $12.2 million decrease in the fair value of estimated contingent consideration for our Skinnygirl ready-to-serve cocktail business based on revised estimated sales levels, which was partially offset by accelerated depreciation expense (included in "Cost of goods sold") incurred in connection with integrating the Pinnacle business into our operations.
