  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 laws and transferred to the appropriate state. For value received,
