I need a formula that will show the "Header" that correlates with the first time a value drops by at least 90%. In the example below, in the Yellow column, it should say "Q4 2015".

Please help! This data package is huge. I need a formula to apply or I may spend the next 10 years doing it manually.

Thanks!

Excel Facts

Repeat Last Command
Pressing F4 adds dollar signs when editing a formula. When not editing, F4 repeats last command.
Perhaps this will make more sense as the original table had multiple rows of data
