Mattel Inc. has agreed to sell $500 million in senior unsecured notes on Thursday.

The El Segundo toymaker’s notes were sold in two groups, according to IFR, a Thomson Reuters tracking service. One group of notes pays 4.3 percent and matures in 2010. The other pays 6.2 percent and matures in 2040. Moody’s rated both issues Baa2 with a “stable” outlook.

The company has said it plans to use proceeds for general corporate purposes, including paying off some debt due next year. The offering is expected to close by Sept. 28.

Shares closed up 20 cents, or less than a percent, to $23.22.
