 The IRS requires that we report the cost basis of certain shares acquired after January 1, 2011. If your shares were covered by the
legislation and you have sold or transferred the shares and requested a specific cost basis calculation method, we have processed as requested. If you did not specify a cost basis calculation method, we have defaulted to the first in, first out
(FIFO) method. Please visit our website or consult your tax advisor if you need additional information about cost basis. 
If you do not keep in contact with us or
do not have any activity in your account for the time periods specified by state law, your property could become subject to state unclaimed property could become subject to state unclaimed property laws and transferred to the appropriate state.
