extent to which you feel these deposits are vulnerable to flight
in
an increasing rate environment.

Changes in interest rates... - page 13
3. This risk applies to virtually any bank.  Please specifically
identify any particular risk that the company or bank face in this
regard or indicate that there is no such particular risk.

4. Given the apparent materiality of your two principal deposit
sources, that is, title company and business deposits, please
discuss
each of these.  Consider including the nature of each type, how
you
compete for these deposits, including any special advantage that
you
have, and the risk of flight of these deposits in an increasing
rate
environment.  We note the new, related risk factor at the top of
page
