The Consolidated Statements of Operations above reflect the adoption of the new standards related to revenue recognition and retirement benefits, as well as other classification changes described in this Form 8-K. These recast results were derived from unaudited financial statements included in the Quarterly Reports on Form 10-Q during the year ended December 31, 2016.

Operating Expense, adjusted. We adjust for the following items to determine operating expense, adjusted, as described below. Adjusting for these items allows investors to understand and analyze our core operational performance in the periods shown.

Mark-to-Market ("MTM") adjustments and settlements. MTM adjustments are defined as fair value changes recorded in periods other than the settlement period. Such fair value changes are not necessarily indicative of the actual settlement value of the underlying hedge in the contract settlement period. Settlements represent cash received or paid on hedge contracts settled during the period. These items adjust fuel expense to show the economic impact of hedging, including cash received or paid on hedge contracts during the period.

Pilot contract impact, normalized. Delta’s new pilot contract was ratified on December 1, 2016 and was retroactive to January 1, 2016. As a result, Delta recognized $380 million in retroactive wages and other benefits in the December 2016 quarter that related to previous quarters.

The following tables present reconciliations of operating expense, adjusted as previously reported.

Net Income, adjusted. We adjust for MTM adjustments and settlements, for the same reasons described above under the heading operating expense, adjusted, and the following items to determine net income, adjusted:

Investment MTM adjustments. We record our proportionate share of earnings from our equity investments in Virgin Atlantic and Aeroméxico in non-operating expense. We adjust for these MTM adjustments to allow investors to understand and analyze the company’s core financial performance in the periods shown.

Tax reform charge. As a result of the Tax Cuts and Jobs Act of 2017, Delta recognized a one-time charge of $150 million in the December 2017 quarter from the revaluation of its deferred tax assets and liabilities. We adjust for this charge to allow investors to understand and analyze the company's core financial performance in the periods shown.

Pre-Tax Margin, adjusted. We adjust for MTM adjustments and settlements and pilot contract impact, normalized, for the same reasons described above under the heading operating expense, adjusted, and third-party refinery sales and investment MTM adjustments to determine pre-tax margin, adjusted. Adjusting for these items allows investors to understand and analyze our core operational performance in the periods shown.

Third-party refinery sales. Delta's refinery segment provides jet fuel to the airline segment from its own production and from jet fuel obtained through agreements with third parties. Activities of the refinery segment are primarily for the benefit of the airline. However, from time to time, the refinery sells fuel by-products to third parties. These sales are recorded gross within other revenue and other operating expense.

Investment MTM adjustments. We record our proportionate share of earnings from our equity investments in Virgin Atlantic and Aeroméxico in non-operating expense.

Total Revenue Per Available Seat Mile "TRASM", excluding refinery. We adjust TRASM for refinery sales to third parties to determine TRASM, adjusted because these revenues are not related to our airline segment. TRASM, excluding refinery therefore provides a more meaningful comparison of revenue from our airline operations to the rest of the airline industry.

Non-Fuel Unit Cost or Cost per Available Seat Miles, Excluding Profit Sharing ("CASM-Ex"). We adjust CASM for the following items to determine CASM-Ex, excluding profit sharing for the reasons described below:

Aircraft fuel and related taxes. The volatility in fuel prices impacts the comparability of year-over-year financial performance. The adjustment for aircraft fuel and related taxes (including our regional carriers) allows investors to understand and analyze our non-fuel costs and year-over-year financial performance.

Other expenses. Other expenses include aircraft maintenance and staffing services we provide to third parties, our vacation wholesale operations, and refinery cost of sales to third parties. Because these businesses are not related to the generation of a seat mile, we adjust for the costs related to these sales to provide a more meaningful comparison of the costs of our airline operations to the rest of the airline industry.

Pilot contract impact, normalized. Delta’s new pilot contract was ratified on December 1, 2016 and was retroactive to January 1, 2016. As a result, Delta recognized $380 million in retroactive wages and other benefits in the December 2016 quarter that related to previous quarters.

The following tables present reconciliations of CASM-Ex as previously reported.
