# Mesabi Trust skips October distribution, initiates arbitration against Northshore and Cliffs for royalty underpayment

## Summary
- No distribution declared for October 2022; same period last year was $1.42 per unit.
- Northshore operations idle until at least April 2023, prompting trustees to maintain reserves.
- Arbitration filed against Northshore and Cliffs for underpayment of royalties in 2020-2022 using incorrect pricing.
- Trust seeks damages and declaratory relief on documentation and royalty accrual timing.
- Uncertainty also from Cliffs' swing operation plan, increased scrap iron use, and economic factors.
