State Street Corporation's Schedule 13G discloses beneficial ownership of 1,605,211 shares (4%). The filing attributes holdings to multiple State Street advisory subsidiaries, indicating custody/management across funds and separate accounts.

Future disclosures could show portfolio turnover; stakeholder voting alignment depends on how those advisory entities instruct votes. Timing and cash‑flow treatment are not detailed in the excerpt.

Compliance / Corporate Governance Specialist

Filing is a passive 13G disclosure, not an active takeover signal.

The submission follows Schedule 13G reporting conventions and classifies multiple State Street entities (e.g., SSGA Funds Management) under Item 7, consistent with holdings held in advisory capacities. Shared voting/dispositive power figures are provided verbatim.

As a 13G, this indicates passive investment intent at the reporting date; any change in intent would require a different filing.

Schedule 13G regulatory

"Item 1. Name of issuer: NORTHWEST NATURAL HOLDING; form type shown as SCHEDULE 13G"

A Schedule 13G is a formal document that investors file with the government when they acquire a large ownership stake in a company, usually for investment purposes rather than control. It helps keep the public informed about who owns significant parts of a company's shares, which can influence how the company is managed and how investors make decisions. Filing this schedule is important for transparency and understanding the ownership landscape of publicly traded companies.

Shared dispositive power regulatory

Investment adviser (IA) financial

"Item 7. SSGA FUNDS MANAGEMENT, INC. (IA); STATE STREET GLOBAL ADVISORS EUROPE LIMITED (IA)"

An investment adviser (IA) is a person or firm that provides personalized guidance on buying, selling, or holding investments and often manages client portfolios for a fee. Investors should care because an IA has a legal duty to act in the client's best interest—think of them as a navigator who plans and steers your financial journey—so their advice, fee structure and potential conflicts can directly affect returns and financial risk.
