Adjusted EBITDA, as we define it, is operating income adjusted for depreciation, depletion, amortization, basis of real estate sold, unallocated pension service costs and special items. Adjusted EBITDA excludes results from joint ventures. Adjusted EBITDA should not be considered in isolation from, and is not intended to represent an alternative to, our GAAP results. (2) Net earnings for 2017, 2018, 2019 and 2020 include net charges of $52 million, $122 million, $354 million and $285 million, respectively, of after-tax non-operating special items which are reported in non-operating pension and other post-employment benefit costs, interest income and other, interest expense, net, and income taxes.

(1) Adjusted EBITDA is a non-GAAP measure that management uses to evaluate the performance of the company. Adjusted EBITDA, as we define it, is operating income adjusted for depreciation, depletion, amortization, basis of real estate sold and special items. Adjusted EBITDA should not be considered in isolation from, and is not intended to represent an alternative to, our GAAP results. We have not provided a reconciliation of forecasted Adjusted EBITDA related to Natural Climate Solutions to the most comparable GAAP measure because Adjusted EBITDA excludes the impact of certain items described in the definition above and management cannot estimate the impact these items will have on Adjusted EBITDA without unreasonable effort. We believe that the probable significance of providing these forward-looking non-GAAP financial measures without a reconciliation to operating income is that investors and analysts will have certain information that we believe is useful and meaningful regarding our Natural Climate Solutions business, but they will not have that information on a GAAP basis. As a result, investors and analysts may be unable to accurately compare the expected impact to our historical results or the results or expected results of other companies that may have treated such matters differently. Management believes that, given the inherent uncertainty of forward-looking statements, investors and analysts will be able to understand and appropriately take into account the limitations in the information we have provided. Investors are cautioned that we cannot predict the occurrence, timing or amount of all non-GAAP items that we exclude from Adjusted EBITDA. Accordingly, the actual effect of these items, when determined, could potentially be significant to the calculation of Adjusted EBITDA over the medium-term.
