Convert word document to pdf and copy the column values

Hi,

I have a document library with column A, COLUMN B and column C

Created event receiver to convert word document to pdf using word automation services if column A value is "Completed" and save pdf document back to the same library with same name.

My question is, what would be the best way to copy Column A, B, C values of word document and copy to the columns for PDF document?

Can anybody advise me on this?

Any help would be greatly appreciated.

Thank you,

AA.
