When must Schedule 13D be filed after acquiring beneficial ownership of more than 5%?

Schedule 13D must be filed within 10 days of acquiring beneficial ownership of more than 5% of a class of equity securities registered under the Securities Exchange Act of 1934. This requirement is established to ensure timely disclosure of significant ownership positions to the market, allowing other investors and the public to be informed about the potential influence or control an individual or institution may have over the company in which they are investing.

Acquiring more than 5% signifies a substantial interest that could potentially influence corporate governance or strategy, which is why regulators mandate this disclosure within a specific timeframe. This allows the market to maintain transparency and facilitate informed decision-making among investors.

The other choices reflect incorrect timeframes for filing. For instance, the 30-day or immediate requirements do not align with the established regulations, and the 5-day option is also shorter than the mandated timeframe. The 10-day period thus stands as the correct and legally required duration for filing Schedule 13D.
