解释：
Sale of obsolete equipment for $69,000 - cash inflow from investing.
Converted $43,000 of preferred shares to common shares - non-cash transaction.
Received interest of $15,000 - cash inflow from operations.
Paid dividends of $26,000 - cash outflow from financing.
New bonds principle of $20,000 - cash inflow from financing
Withdrawal principal of $36,000 - cash inflow of investing
CFI = 69,000 + 36,000=105,000
CFF = -26,000 + 20,000 = -6,000
Converted $43,000 worth of preferred shares to common shares，优先股转换成普通股不产生现金流，这样理解对么老师？
