Walmart Inc plans to sell dollar-denominated investment-grade bonds in as many as five parts on Monday.

The longest portion of the offering, a 10-year security, may yield 0.7 percentage point more than Treasuries, according to a person with knowledge of the matter. The retailer plans to use the proceeds from the sale for general corporate purposes, potentially including refinancing, said the people, asking not to be identified as the details are private.
