we also have a committed corporate credit facility , uncommitted lines of credit and a commercial paper program available to support our operating needs .
we continue to maintain a disciplined approach to managing liquidity , with flexibility over significant uses of cash , including our capital expenditures , cash used for new acquisitions , our common stock repurchase program and our common stock dividends .
from time to time , we evaluate market conditions and financing alternatives for opportunities to raise additional funds or otherwise improve our liquidity profile , enhance our financial flexibility and manage market risk .
our ability to access the capital markets depends on a number of factors , which include those specific to us , such as our credit ratings , and those related to the financial markets , such as the amount or terms of available credit .

additionally , we may be required to make payments to minority shareholders in certain subsidiaries if they exercise their options to sell us their equity interests .

we also paid $ 0.9 in up-front payments and $ 100.8 in deferred payments for prior-year acquisitions as well as ownership increases in our consolidated subsidiaries .
