director compensation plan financial

"stock received as compensation for service as a director pursuant to a director compensation plan"

Dividend Reinvestment and Stock Purchase Plan financial

"automatic reinvestment of dividends under the ACNB Corporation Dividend Reinvestment and Stock Purchase Plan"

A dividend reinvestment and stock purchase plan lets investors automatically use cash dividends to buy additional shares and often make extra share purchases directly from the company, usually at low or no commission. Think of it as an automatic savings plan for stock: dividends and optional contributions are turned into more shares, helping ownership grow through compounding and making regular investing simple and low-cost—key for long-term investors.

Section 16 of the Securities Exchange Act of 1934 regulatory

"exempt from the reporting requirements of Section 16 of the Securities Exchange Act of 1934"

A provision of federal securities law that requires company insiders—directors, officers and large shareholders—to publicly report their stock holdings and trades and to surrender any “short-swing” profits from purchases and sales within a six-month window. It acts like a rule that forces leaders to announce their trades and prevents quick buy-sell windfalls, giving investors transparency into insider activity and reducing opportunities for unfair gain.
