[solved] Can you identify the major sources of funding used by the company

First here is an explanation: There are 4 main parts to the Statement of Cash Flows: 1. Net cash provided by operating activities. 2. Net cash used in investing activities. 3. Net cash used in financing activities and 4. “NET CHANGE IN CASH AND CASH EQUIVALENTS.” (Yes, it is a bit strange to see all capital letters in this last category.) Cash inflows show as positive numbers. Cash outflows show as negative numbers with parentheses around them.
Cash Flow Net cash provided by operating activities was $3.2 billion in 2015. The majority of that came from $2.2 billion of net income and $1.0 billion of depreciation and amortization. (Note: Depreciation is a non-cash charge. The company has to pay cash soon after it purchased the airplanes and other property.) Net cash used in investing activities was ($1.9) billion. That was essentially the same as the amount of capital expenditures ($2.0) billion. The purchase and sale of short term investments were similar to each other. Net cash used in financing activities was ($1.0) billion. Southwest spent ($1.2) billion on the repurchase of common stock. It borrowed $0.5 billion and had other payments. NET CHANGE was positive $0.3 billion.
So in sum, Southwest Airlines Company had 3 Net cash from operating activities as the primary source of funding. Net income provided the most at $2.2 billion with depreciation next at $1 billion. The company did borrow $0.5 billion.
