Please be advised that corrections are required in Table 2.3 of that report.

Therefore, we are enclosing three (3) copies of the revised Table 2.3 as page changes to our previously transmitted Summary Report for your use.
If you have any questions regarding this matter, please contact this office.
Very truly yours h
