Assumptions
  • 20–40 analyst hours per rating pack today; 5–10 hours with an agent, including review
  • 4–20 rating packs a year for one team
  • $150–250 per hour loaded cost
  • Tool or build cost $10,000–40,000 a year (in-house)

How you get thereFour steps from prompting to an agentic workflow; most teams start at step 2.
1 · PromptingAn analyst asks a chat tool about one rating pack.
Needs: an approved AI tool, a confidentiality policy.
Risk: unchecked answers, data pasted outside policy.
2 · WorkflowA fixed pipeline extracts the same fields into your template every time.
Needs: field definitions, a template, document parsing.
Risk: breaks silently when formats change.
Typical starting point
3 · AgentIt watches the inbox or data room, runs the checks and drafts the output.
Needs: inbox/doc-store access, system write-back, logging.
Risk: acting on a misread; needs review gates.
The automated lane above
4 · Agentic workflowSeveral agents work across the deal or book; people approve exceptions.
Needs: shared data model, permissions, audit trail, exception queue.
Risk: errors compound across steps; needs monitoring.

How it works

Full title: The private letter rating pack: assemble what the rating agency and the insurer's regulator will ask for, with every figure sourced

“Rating agency data request: 48 items. 41 filled from the closing set and the model, each cited. 7 need the deal team.”

Scenario

SAMPLE: A loan is being placed partly with an insurance-company buyer that needs a private letter rating. The rating agency sends a data request, and the insurer will need to file the rating rationale with the NAIC.

What the human still decides

The deal team and the rated entity decide what is shared, and the agency decides the rating. What can go wrong: a figure from an early model version goes into the pack, or confidential information goes to the wrong party. Keep one approved source for every figure.

Why it matters

Private letter ratings for private credit held by insurers are under closer review. The NAIC requires Private Rating Letter Rationale Reports to be filed and to 'possess analytical substance', and from 1 January 2026 its staff can challenge filing-exempt and private-letter-rated designations. Clean, consistent rating packs matter more.

What the record shows

Checked 2026-10-15.

The NAIC SVO now has discretion to challenge private letter ratings on filing-exempt securities, so the pack has to stand up to a second reader. DBRS notes fund structures borrowing CLO features, such as sub-line securitizations and senior fee notes, and 18% of its middle-market ratings in CCC (high) to C.

Try it: prompt and data
Map this rating agency data request {request} to {closing_set}, {model}, {credit_agreement}. Fill each item with a cited figure or document. Mark items you cannot source. Flag any figure that differs between documents. Do not characterize credit quality.

Data

Demo uses clearly labeled SAMPLE (fictional) documents. Real deal documents are confidential and often under NDA: run this only inside your firm's approved environment, never in a consumer AI tool.
