   3. c) If a holder fails to maintain records required by Section 15-404 of the Act, the administrator may determine the value of property due using a reasonable method of estimation based on all information available to the administrator, including extrapolation and use of statistical sampling when appropriate and necessary, consistent with examination procedures and standards in this Part.
   4. d) Both the records retention period of Section 15-404 of the Act and the statute of limitations in Section 15-610(b) of the Act are 10 years.

[765 ILCS 1026/15-610(b)] If the statute of limitations has been tolled because the holder failed to either report property or provide express notice to the administrator and the holder fails to maintain sufficient records of items that were not reported as unclaimed, to allow examination to determine whether the holder has complied with the Act [765 ILCS 1026/15-404(5)], the administrator may use estimation in an examination of that holder pursuant to Section 15-1006 of the Act and this Part.
