At September 30, 2015, we had revolving credit agreements with various banks permitting aggregate borrowings of up to $4.35 billion pursuant to a $2.20 billion revolving credit agreement and a $2.15 billion multicurrency revolving credit agreement, both of which expire in May 2019. As of September 30, 2015, there were no borrowings under these revolving credit agreements. The undrawn portions of these revolving credit agreements are also available to serve as backup facilities for the issuance of commercial paper. As of September 30, 2015, our maximum commercial paper borrowing limit was $4.35 billion. We use our commercial paper borrowings for general corporate purposes, including the funding of potential acquisitions, debt refinancing, and repurchases of our common stock. The need for commercial paper borrowings arises when the use of domestic cash for acquisitions, dividends, and share repurchases exceeds the sum of domestic cash generation and foreign cash repatriated to the U.S.

On May 4, 2015, we completed the previously announced optional remarketing of the 1.550% junior subordinated notes, which were originally issued as part of our equity units on June 18, 2012. As a result of the remarketing, these notes were redesignated as our 1.778% junior subordinated notes due May 4, 2018. The 1.778% junior subordinated notes are effectively subordinated to existing or future preferred stock and indebtedness, guarantees and other liabilities, and are not redeemable prior to maturity. On August 3, 2015, we received approximately $1.1 billion from the proceeds of the remarketing, and issued approximately 11.3 million shares of Common Stock to settle the purchase obligation of the holders of the equity units under the purchase contract entered into at the time of the original issuance of the equity units.

On May 1, 2015, we repaid all 4.875% notes due in 2015, representing $1.2 billion in aggregate principal. On June 1, 2015, we repaid all floating rate notes due in 2015, representing $500 million in aggregate principal. On May 4, 2015, we issued $850 million aggregate principal amount of 4.150% notes due May 15, 2045. On May 22, 2015 we issued €750 million aggregate principal amount of 1.250% notes due May 22, 2023. The net proceeds from these debt issuances were used primarily to repay the notes that matured during the quarter ended June 30, 2015.

We have an existing universal shelf registration statement filed with the Securities and Exchange Commission (SEC) for an indeterminate amount of equity and debt securities for future issuance, subject to our internal limitations on the amount of equity and debt to be issued under this shelf registration statement.
