Count Unique Values with Duplicates in Multiple Columns

Greetings everyone!

I want to provide a function which will count the number of applications greater than or equal to 25 days over due date while only considering the most recent individual "Application Type" per "Company No.". By most recent I mean that an "Updates" over rides an "Originals". If an application has multiple "Updates" only consider the days over due date of the most recent "Update".

I have been trying various iterations of the following function: =SUM(IF(FREQUENCY(IF(MATCH(A3:A8,A3:A8,0))))),ROW(A3:A8)-ROW(A3)+1),1)). However, as stated above I am trying to count the most recent application and this function is not quite fitting the bill.

I have attached a sample file which shows the highlighted results I would like the function to count.

Any help is greatly appreciated! Please let me know if anything is unclear.
