Renewable Diesel Driving Low Carbon Results

Non-GAAP Disclosures Renewable Diesel Adjusted EBITDA per Gallon Renewable diesel adjusted EBITDA is defined as DGD's operating income adjusted to reflect the blender's tax credit and excluding depreciation and amortization expense. Operating income is adjusted to reflect the blender's tax credit in the proper period. The blender's tax benefit recognized in 2019 is attributable to volumes blended during 2019 and 2018 and was recognized in December 2019 because the U.S legislation authorizing the credit was passed and signed into law in that month. The benefit recognized in 2018 is attributable to volumes blended during 2017 and was recognized in February 2018 because the U.S. legislation authorizing the credit was passed and signed into law in that month. VLO believes adjusting for these items provides improved comparability between periods. Renewable diesel EBITDA per gallon is renewable diesel adjusted EBITDA divided by DGD's renewable diesel sales volume for the period. Sales volumes are calculated by multiplying sales volumes per day by the number of days in the applicable period. Free Cash Flow VLO defines free cash flow as net cash provided by operating activities less capital expenditures, deferred turnaround and catalyst cost expenditures, investments in joint ventures, and changes in current assets and liabilities. VLO believes that the presentation of free cash flow provides useful information to investors in assessing VLO's ability to cover ongoing costs and VLO's ability to generate cash returns to stockholders. The GAAP measures most directly comparable to free cash flow are net cash provided by operating activities and net cash used in investing activities. Adjusted Net Cash Provided by Operating Activities Defined as net cash provided by operating activities excluding the items noted below. VLO believes adjusted net cash provided by operating activities is an important measure of its ongoing financial performance to better assess its ability to generate cash to fund VLO's investing and financing activities. The basis for VLO's belief with respect to each excluded item is provided below. • Changes in current assets and current liabilities - Current assets net of current liabilities represents VLO's operating liquidity. VLO believes that the change in its operating liquidity from period to period does not represent cash generated by VLO's operations that is available to fund VLO's investing and financing activities. DGD's adjusted net cash provided by operating activities attributable to VLO's joint venture partner's ownership interest in DGD - VLO is a 50/50 joint venture partner in DGD and consolidate DGD's financial statements; as a result, all of DGD's net cash provided by operating activities (or operating cash flow) is included in VLO's consolidated net cash provided by operating activities. DGD's partners use DGD's operating cash flow (excluding changes in its current assets and current liabilities) to fund its capital investments rather than distribute all of that cash to themselves. Nevertheless, DGD's operating cash flow is effectively attributable to each partner and only 50 percent of DGD's operating cash flow should be attributed to VLO's net cash provided by operating activities. Therefore, net cash provided by operating activities has been adjusted for the portion of DGD's operating cash flow attributable to VLO's joint venture partner's ownership interest because VLO believes that it more accurately reflects the operating cash flow available to VLO to fund VLO's investing and financing activities.
