On May 1, 2013, we announced the pricing of two series of senior unsecured notes for an aggregate principal amount of $1 billion. The notes consist of the following:

• $500 million of 1.00% notes due May 1, 2018

• $500 million of 2.25% notes due May 1, 2023

We expect to use the proceeds of this offering for repayment of debt. The debt offering is expected to close on May 8, 2013.
