US meat processor Smithfield Foods has filed a registration statement and preliminary prospectus for a public offering of fixed rate senior unsecured notes.

In a filing with the Securities and Exchange Commission (SEC), Smithfield said it expected the offering to be at least US$500m, and that the proceeds would be used to pay down debt.

The offering is expected to close on Friday (22 June), and is being marketed through Citigroup Corporate and Investment Banking and JP Morgan Securities.
