Institutional Ownership Analyst

The filing reports beneficial ownership of 4,603,853 shares with sole dispositive power and 2,988,929 shares of sole voting power as of the schedule. This aligns with Schedule 13G reporting for large passive investors.

Ownership is held by multiple affiliated entities for account holders; cash-flow treatment and any plans to trade are not stated in the provided excerpt. Subsequent filings would disclose changes in holdings.

Corporate Governance Specialist

Disclosure highlights voting and dispositive authority across affiliates.

The schedule identifies Cohen & Steers, Inc. and affiliated advisors and gives principal addresses and citizenships. It specifies that securities are held "for the benefit of their respective account holders."

Because the filing is a passive Schedule 13G, it signals passive investment reporting rather than an active acquisition strategy; the disclosed percentages and vote counts are the key observable governance metrics.

4 terms

Schedule 13G regulatory

"Item 1. (a) Name of issuer: National Storage Affiliates Trust"

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.

Beneficial ownership regulatory

"Item 4. (a) Amount beneficially owned: 4,603,853"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

Sole dispositive power regulatory

"(iii) Sole power to dispose or to direct the disposition of: 4,603,853"

Sole dispositive power is the exclusive legal authority to decide what happens to a security — for example, whether to sell, transfer, or retain shares — without needing anyone else’s permission. Investors care because it signals who truly controls the economic outcome of an investment: like holding the only key to a safe, the holder can realize gains or losses and may trigger regulatory reporting, insider rules, or influence over corporate ownership.

Sole voting power regulatory

"(i) Sole power to vote or to direct the vote: 2,988,929"

Sole voting power is the exclusive right to cast votes attached to a shareholder’s stock without needing approval from anyone else. Like holding the only remote control for a TV, it lets that holder decide corporate matters such as board members, mergers, and policy changes, making it important to investors because it concentrates control and can strongly influence a company’s strategy and the value of its shares.
