[SCHEDULE 13G] Western Asset Investment Grade Defined Opportunity Trust Inc. SEC Filing

Rhea-AI Filing Summary

SSR Mining Inc. (SSRM) submitted an amended Form 4 on 07/02/2025 reporting that director Thomas R. Bates Jr. acquired 2,217 Deferred Share Units (DSUs) on 07/01/2025. Each DSU entitles the holder to the cash value of one common share when the director retires from the board. The transaction lifts Bates’s directly held DSU balance to 121,798 units; no dispositions or sales were disclosed. Because DSUs settle in cash rather than shares, the filing highlights additional, albeit modest, equity-aligned compensation for the director. No non-derivative share transactions, option exercises, or 10b5-1 plan indications appear in the filing.

Positive

• Director acquired 2,217 DSUs, increasing direct derivative holdings to 121,798 units and demonstrating continued equity-linked compensation alignment.

Negative

• None.

Insights

Corporate Governance Analyst

TL;DR Small DSU grant to SSRM director; minimal valuation impact but signals continued board-level alignment with shareholders.

The amended Form 4 shows Director Thomas R. Bates Jr. receiving 2,217 DSUs, raising his direct derivative position to 121,798 units. DSUs vest immediately and convert to cash on board departure, creating long-term incentive alignment. However, the dollar value—roughly equal to one share per DSU—represents a negligible fraction of SSR Mining’s market capitalization, so market impact should be minimal. No sales occurred, and ownership remains direct, eliminating complexities around indirect control. Overall, the filing is routine and governance-neutral, with no material implications for earnings, liquidity, or strategy.
