Final answer:
Preferred dividends declared and paid, a decrease in accounts receivable, and an increase in inventory should be added to net income when computing net cash flows from operating activities using the indirect method. A decrease in accounts payable should be subtracted from net income.
Step-by-step explanation:
In computing net cash flows from operating activities using the indirect method, several adjustments need to be made to net income. One of these adjustments is to add back any non-cash expenses, such as depreciation and amortization. Another adjustment is to add back any loss on the sale of assets and deduct any gain on the sale of assets since these gains and losses do not affect cash flows from operations.
With regards to the given options, preferred dividends declared and paid, a decrease in accounts receivable, and an increase in inventory should all be added to net income when computing net cash flows from operating activities using the indirect method. This is because these changes do not involve the movement of cash and therefore need to be adjusted to reflect the actual cash flows.
On the other hand, a decrease in accounts payable should be subtracted from net income when computing net cash flows from operating activities using the indirect method. This is because a decrease in accounts payable represents a cash outflow since it involves the payment of liabilities.
