Attestation Roster · Public

The credentialed actuaries who have attested to this methodology.

An attestation is a credentialed actuary's signed statement that they have read the methodology document at the published version, applied their professional judgment, and find the document defensible. Attestations are version-pinned; a methodology version bump requires re-attestation. Compensation arrangements, where any exist, are disclosed publicly alongside each entry.

Attested v1.0 Date 2026 Compensation Demonstration entry — no live engagement

This entry is the demonstration signing actuary used on the published Sample Workforce Exposure Forecast (/sample-workforce-exposure-forecast.pdf). The signer name is illustrative; the methodology v1.0 to which the Sample is pinned is the same v1.0 document any live signing actuary would attest to. Live attestations appear immediately above this entry as they are submitted and verified.

Additional v1.0 attestations are being accepted now. Credentialed actuaries (ASA, FSA, MAAA, FCAS, ACAS) interested in attesting may submit per the protocol below.
Methodology version v1.1 Planned — Pending Commissioned Review
v1.1 will publish following an external commissioned actuarial review of v1.0. Refinements will include per-marker Bühlmann constants from production data, per-marker lag haircuts from claim-experience linkage, coefficient-uncertainty propagation in the bootstrap, and a piecewise or saturating trajectory model. v1.0 attesters will be notified to review and re-attest when v1.1 publishes.

Submitting an attestation

Credentialed actuaries (ASA, FSA, MAAA, FCAS, ACAS) may submit an attestation by reading the published v1.0 document and contacting Metra at care@usemetra.com with subject line “Methodology Attestation — v1.0”. The submission carries name, credential, firm, credential number, optional firm letterhead document, and a statement of attestation. Compensation arrangements (where any exist) are disclosed publicly on this roster alongside the entry.

Critiques and counter-derivations on v1.0 are equally welcomed and are logged into the v1.1 drafting input. Subject line “Methodology Review — v1.0”.
