Insights

Financial Analyst

TL;DR: State Street reports a sub-5% position in ON with shared voting/dispositive authority, indicating portfolio management activity, not control.

State Street discloses 19.39 million ON shares (4.6%), with all voting and disposition powers reported as shared. The split between shared voting (12.11 million) and shared dispositive power (19.39 million) suggests passive or client-directed holdings rather than an active control stake. Multiple SSGA entities are listed and classified as IA (investment adviser), consistent with asset-management custodial arrangements.

Corporate Governance Expert

TL;DR: A routine institutional disclosure showing aggregated client positions; not a governance-changing stake.

The Schedule 13G is consistent with passive/investment-adviser reporting: State Street reports shared powers and explicitly certifies holdings are in the ordinary course of business and not intended to influence control. The identification of several State Street Global Advisors subsidiaries as IA entities supports that these positions are managed across client portfolios rather than held for corporate control purposes.
