Note 4.    Debt

Short-Term Debt

We have a debt financing program of up to $3.0 billion through the issuance of commercial paper. Net proceeds from this program are used for general corporate purposes. At December 31, 2010 and 2011, we had $3.0 billion and $750 million of commercial paper outstanding recorded as short-term debt with weighted-average interest rates of 0.3% and 0.1%. In conjunction with this program, we have a $3.0 billion revolving credit facility expiring in July 2016. The interest rate for the credit facility is determined based on a formula using certain market rates. At December 31, 2010 and 2011, we were in compliance with the financial covenant in the credit facility. No amounts were outstanding under the credit facility at December 31, 2010 and December 31, 2011.

In December 2010, we issued a secured promissory note in the amount of $468 million with an interest rate of 1.0% and a one-year maturity date. Proceeds were used for the acquisition of an office building in New York City. In December 2011, we extended the maturity date of the note to December 2012. As of December 31, 2010 and 2011, the outstanding balance was $468 million.

The estimated fair value of the short-term debt approximated its carrying value at December 31, 2010 and December 31, 2011.

The effective interest yields of the 2014, 2016, and 2021 Notes were 1.258%, 2.241%, and 3.734%, respectively. Interest on the Notes is payable semi-annually in arrears on May 19 and November 19 of each year. We may redeem the Notes at any time in whole or from time to time in part at specified redemption prices. We are not subject to any financial covenants under the Notes. We used the net proceeds from the issuance of the Notes to repay a portion of our outstanding commercial paper and for general corporate purposes. The total estimated fair value of the Notes was approximately $3.2 billion, which is based on quoted prices for our publicly-traded debt as of December 31, 2011.

At December 31, 2011, future principal payments for the Notes were as follows (in millions):
