Financial Overview

For the quarter, net sales were $2.21 billion, up 6%, including an unfavorable change in currency exchange rates of 1 percentage point. On a regional basis, third quarter gross sales increased 3% in the North American Region, which consists of the U.S., Canada and American Girl, with no impact from changes in currency exchange rates. For the International Region, gross sales increased 9%, including an unfavorable impact of currency exchange rates of 2 percentage points. Operating income for the quarter was $528.2 million, compared to prior year’s operating income of $487.4 million.

The Company’s debt-to-total-capital ratio was 36.5%. For the first nine months of the year, the Company’s cash and equivalents decreased by approximately $929 million, compared with a decline of approximately $1.09 billion during the same period last year.

For the first nine months of the year, cash flows used for operating activities were approximately $321 million, an increase of $220 million compared to approximately $101 million of cash flows used for operating activities in the same period of 2012. The increase is primarily due to higher working capital usage, partially offset by higher net income. Cash flows used for investing activities were approximately $176 million, a decrease of $657 million, compared to approximately $833 million in 2012, driven primarily by the prior year acquisition of HIT Entertainment. Cash flows used for financing and other activities were approximately $432 million, an increase of $279 million, compared to approximately $153 million in 2012, primarily due to higher share repurchases and repayments of long-term debt, partially offset by net proceeds received from the issuance of long-term debt.

Capital Deployment

The Company announced today that its Board of Directors declared a fourth quarter cash dividend of $0.36 per share on the Company’s common stock. The dividend will be payable on December 13, 2013, to stockholders of record on November 27, 2013. The dividend is the final of four quarterly dividends the Company will have paid this year, reflecting an annualized dividend of $1.44 per share, which represents a 16% increase to last year’s total dividends. During the third quarter of 2013, the Company repurchased 6.1 million shares of its common stock at a cost of approximately $259 million.
