From Andrew Mitchel’s International Tax Blog:
In Notice 2011-54, the I.R.S. has provided an additional extension for persons having signature authority over, but no financial interest in, a foreign financial account in 2009 or earlier calendar years for which the reporting deadline was extended by Notice 2009-62 or Notice 2010-23. These persons now have until November 1, 2011, to file FBARs with respect to those accounts. The deadline for reporting signature authority over, or a financial interest in, foreign financial accounts for the 2010 calendar year remains June 30, 2011.
