[1] Net income attributable to Cash America International, Inc. for the third quarter of 2013 did not follow the normal seasonal trend due to the income tax benefit in connection with the Creazione Deduction and the expenses related to the 2013 Litigation Settlement. See Notes 12 and 13.

[2] Net income attributable to Cash America International, Inc. for the third and fourth quarter of 2012 did not follow the normal seasonal trend due to the expenses recognized in connection with the Ohio Reimbursement Program and the Mexico Reorganization. See Notes 13 and 23.

[3] Includes vested and deferred restricted stock units of 307, 287 and 231, as well as shares in the Company's nonqualified deferred compensation plan of 31, 31 and 32 for the years ended December 31, 2013, 2012 and 2011, respectively.

[4] For the years ended December 31, 2013, 2012 and 2011, includes shares related to unvested restricted stock unit awards. For the years ended December 31, 2012 and 2011, also includes shares related to outstanding option awards that were exercisable. Although there were no stock option awards outstanding as of December 31, 2012, the dilutive effect of stock-based compensation is based on weighted amount of outstanding awards during the year; therefore, a portion of the stock option awards outstanding during 2012 are included in this amount.

[5] The sum of the quarterly net income per share amounts may not total to each full year amount presented in the Company's financial statements because these computations are made independently for each quarter and for the full year and take into account the weighted average number of common shares outstanding for each period, including the effect of dilutive securities for that period.

[6] For the years ended December 31, 2013 and 2011, there is an immaterial amount of unvested restricted stock units that are excluded from shares applicable to stock-based compensation because its impact would be anti-dilutive. There were no anti-dilutive shares for the year ended December 31, 2012.
