The IRS requires that the named transfer agent (“we”) report the cost basis of certain shares or units acquired
after January 1, 2011. If your shares or units are covered by the legislation, and you requested to sell or transfer the shares or units using a specific cost basis calculation method, then we have processed as you requested. If you did not specify
a cost basis calculation method, then we have defaulted to the first in, first out (FIFO) method. Please consult your tax advisor if you need additional information about cost basis. 

If you do not keep in contact with the issuer or do not have any activity in your account for the time period specified by
state law, your property may become subject to state unclaimed property laws and transferred to the appropriate state.
