Financial Overview

For the quarter, net sales were $995.6 million, up 7% compared to $928.4 million last year. On a regional basis, first quarter gross sales increased 5% 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 a 2 percentage point unfavorable impact from changes in currency exchange rates. Operating income for the quarter was $65.8 million, compared to prior year’s operating income for the quarter of $28.7 million.

The Company’s debt-to-total-capital ratio of 35.2% is in line with its capital investment framework.

Cash flows used for operating activities were approximately $62 million, compared to approximately $171 million of cash flows from operating activities in 2012. The change is primarily due to higher working capital usage, partially offset by higher net income. Cash flows used for investing activities were approximately $66 million, a decrease of $637 million, driven primarily by the prior year acquisition of HIT Entertainment. Cash flows from financing and other activities were approximately $52 million, compared to cash flows used for financing and other activities of approximately $53 million in 2012. The change was primarily due to the net proceeds received from the issuance of long-term debt, partially offset by repayments of long-term debt and higher dividend payments.

Capital Deployment

The Company announced today that its Board of Directors declared a second quarter cash dividend of $0.36 per share on the Company’s common stock. The dividend will be payable on June 14, 2013 to stockholders of record on May 23, 2013. The dividend is the second of four quarterly dividends the Company expects to pay this year, reflecting an annualized dividend of $1.44 per share, which represents a 16% increase to last year’s total dividends. During the first quarter of 2013, the Company repurchased 240,000 shares of its common stock at a cost of approximately $9 million.
