nawk and regular expression

I have an input file which looks like the example below and I want to format it with 2 columns from the header based on the word "CUSIP" followed by a 9 digit string with first 3 being numeric and in the same line NNN.NN% pattern for the percentage value. (In RED)

I started of with nawk but with my limited knowledge of regex I am stuck any help would help.


input file

Which parts of your solicitor mail file are actually in it? Put them in [code] tags so we can see.

I know which parts you want. I just don't know which of the junk is labels and which is actually in the file -- it's seemingly labelled twice, so at least one of them must be in the file, if not both...

If you use code tags instead of trying to label things ---------------------------like this---------------------- then the bounds of the file will be obvious. And, usefully, color tags like you've already used still work inside [code] tags.
