How JLK Rosenberger Audited 12,750 Pages of Bond Memos With Punchcard Co-audit
JLK Rosenberger is a Top-200 audit and tax firm with deep expertise serving the insurance industry, captive insurance carriers, and high-net-worth clients across the United States and Mexico.
A new procedure that wouldn’t have been attempted
When a new classification standard landed for insurance investment bonds, JLK Rosenberger faced a procedure no firm reasonably runs by hand: read 12,750 pages of offering memoranda across 15 selections, locate the sections that govern classification, and trace each one against an internal flowchart.
Manually, that’s a procedure most firms would scope out. Co-audit made it routine.
Co-audit on the work
Paige Bassoli, an associate at JLK, structured the procedure as a workpaper with testing attributes mapped to the new classification standard and a column for the supporting quote in the offering memo. She wrote the linguistic formula once. Co-audit ran it across all 15 selections, surfaced the relevant sections from each memo, and cited every value back to its page in the source.
From speed to scope
For JLK, the result wasn’t just faster — it was qualitatively different. Co-audit turned a procedure that wouldn’t have been attempted manually into a routine, reviewable, citation-linked workpaper. Speed, in this case, expanded the audit’s scope.
“Co-audit didn’t just make the work faster — it let us do work we wouldn’t have done at all.”
