Schedule 13G/Aregulatory
"Amendment No. 1 ) NEUBERGER REAL ESTATE SECURITIES INCOME FUND INC"
A Schedule 13G/A is an amended public filing with the U.S. securities regulator that updates a previous Schedule 13G, disclosing when an individual or group holds a substantial (typically over 5%) stake in a company and is claiming a passive, non‑controlling intent. Investors monitor these updates because rising or falling holdings can signal changing confidence, potential future moves, or shifts in voting power — like watching a public ledger where large shareholders quietly adjust their positions.
Rule 13d-4regulatory
"Pursuant to Rule 13d-4 of the Securities Exchange Act of 1934"
beneficial ownershipfinancial
"SIA and SFI may be deemed to be the beneficial owner of such shares"
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.
