DineEquity, Inc. on Wednesday said it plans to offer up to $825 million in its senior unsecured notes.

The Glendale owner of Applebee’s Neighborhood Grill & Bar and IHOP Restaurants chains said the notes will be due in 2018 and guaranteed by DineEquity’s current and future domestic subsidiaries.

DineEquity, which owns or operates more than 3,450 Applebee’s and IHOP restaurants, said it intends to use the net proceeds, along with net proceeds from secured debt financing, to pay for previously announced tender offers of old debt issues and to pay financing costs. The company has been working to improve its finances and lower debt from its 2007 acquisition of the Applebee’s chain by selling restaurants to franchisees.

Shares were down 80 cents, or 2 percent, to $40.28 in midday trading on the New York Stock Exchange.
