8-K - OLD SECOND BANCORP INC (0000357173) (Filer)
Notice of Dividend Amount Classification · 100% confidence The document is a Form 8-K filed with the SEC, which is a current report used to announce major events. The key content is the declaration of a cash dividend by the Board of Directors, specifying the dividend amount, record date, and payment date. The document is short (2835 characters) and focuses solely on the dividend declaration event. This matches the definition of a Notice of Dividend Amount (DIV), which announces dividend amounts and payment details to shareholders.
