**Affirmed position.** Dynamic regulation of pituitary mRNAs for bone morphogenetic protein (BMP) 4, BMP receptors, and activin/inhibin subunits in the ewe during the estrous cycle and in cultured pituitary cells. should be assessed against Kaal's source-bound claim that Because policymakers may adopt a suboptimal single trigger design, and because contingent capital has uses at several points in a firm's life cycle, contingent capital securities should be built with sequential triggers rather than one. The current metadata indicates a plausible connection through dynamic regulation, but the defensible response is a qualification until the source text confirms agreement, scope, methods, and limitations.

**Status.** affirmed  **Published.** 2026-07-31

**Holds when.**

- Assumes mandatory issuance of contingent capital securities
- External evidence level: metadata only.
- Mapping review tier: mapping review before claim review.
- The literature-to-claim mapping remains explicitly ambiguous and should not be treated as a settled equivalence.
