During the second quarter of 2012, we recorded an out-of-period adjustment which increased earnings by approximately $5 before tax ($3 after tax) which related to prior years and was associated with vendor liabilities in North America. During the second quarter of 2012, we recorded an out-of-period adjustment which decreased earnings by approximately $4 before tax ($4 after tax) which related to prior years and was associated with brochure costs in Poland. In addition to the adjustments previously mentioned, in 2012, we also recorded out-of-period adjustments in the aggregate of approximately $1 before tax ($5 after tax) that related to prior years.2011During the first quarter of 2011, we recorded out-of-period adjustments associated with Discontinued operations, net of tax for prior periods resulting in a charge of approximately $9, which would have decreased Discontinued operations, net of tax during the fourth quarter of 2010 by approximately $13 and increased a prior period by approximately $4.During the fourth quarter of 2011, we recorded adjustments of approximately $25 before tax ($17 after tax) of which approximately $14 before tax ($10 after tax) related to prior quarters of 2011 and was primarily associated with inventory in our Brazil operations. The remaining fourth quarter out-of-period adjustments of approximately $11 before tax ($7 after tax) related to prior years. During the other quarters of 2011, we also recorded out-of-period adjustments in the aggregate of approximately $10 before tax ($7 after tax) that related to prior years.We evaluated the out-of-period adjustments in 2012 and 2011, both individually and in the aggregate, in relation to the quarterly and annual periods in which they originated and the annual period in which they were corrected, and concluded that these adjustments were not material to the consolidated annual financial statements for all impacted periods.
