Define operating cash flow.

Operating cash flow specifically refers to the cash generated by a company’s normal business operations. This figure is crucial because it reflects the company’s ability to generate cash from its core activities, which is a fundamental aspect of a business's financial health. It excludes cash flows from investment and financing activities, focusing solely on the cash transformation from operations such as selling products or services, and managing working capital.

By isolating these operational activities, operating cash flow provides a clear insight into how well a company can sustain its operations in the long term, cover its operating expenses, and generate profit. This is particularly valuable for stakeholders who seek to understand the efficiency and profitability of a company's routine business activities.

In contrast to the other options, which refer to broader financial metrics or different aspects of cash flow considerations—such as total revenue, overall cash availability after various expenses, or long-term total cash flow—operating cash flow remains specifically tied to the cash created through day-to-day operations. This makes option B the most accurate definition regarding operating cash flow.
