German Chancellor Angela Merkel signaled that policy makers may review Greece's second bailout after international debt inspectors rule on whether the country is meeting the terms of its current aid package.

Greece's "numbers in September, as it now seems, were again different from what we expected under the program," Merkel told Greek broadcaster NET when asked whether the second bailout agreed by European leaders on July 21 will be revised.

"We must now await what the troika, that is the expert mission, finds out and tells us: do we need to renegotiate or don't we need to renegotiate?" Merkel said, according to a transcript provided by her press office late yesterday. "What we would like the most, of course, is that the numbers stay as we know them. But I can't pre-empt the outcome of the troika."
