Root Operational Bottleneck
Intercompany loan interest is computed in a borrowing schedule whose rate is typed each month, often from a stale benchmark, and posted as a single accrual per note.
Control Hazard & Audit Exposure
Rates that are not arm's length produce a tax penalty, and the two entities' interest income and expense do not reverse on consolidation.

Deterministic Intercompany Ledger & Benchmark Rate Post
Intercompany note ledger that applies a stored benchmark rate class to each note and posts paired interest entries in both currencies.
Continuous Assertion Rule
Rate assertion: interest cannot post unless the note cites a benchmark rate record for the accrual period and the paired entities receive equal-and-opposite amounts.
