The individual line items in the Standardized Measure are not comparable with the discounted net cash flow amount (i.e., there is not a linear relationship) due to the application of discounting. The undiscounted cash flows will be spent or received over a 50-year time horizon. As presented in the undiscounted numbers of the Standardized Measure disclosures, cash received or paid in one year has the same value as cash received or paid in 50 years. However, these same cash flows have significantly different values when presented on a discounted basis. Thus, without the appropriate discounting, certain cash flows can appear overweighted or underweighted in a particular line item depending on the timing of those cash flows in relation to others. For example, the vast majority of the future development costs in the Standardized Measure relate to the drilling and completion of proved undeveloped reserves existing as of each measurement date, and the Company must have plans to develop those proved undeveloped reserves within 5 years of their initial recognition. Accordingly, the costs associated with developing these reserves will all be incurred within the 5 years following each measurement date. In addition, these costs may vary significantly from measurement date to measurement date based on the actual timing of the development of our reserves and changes to future development plans. The Company’s abandonment costs, on the other hand, include costs related to all of the Company’s proved reserves and will be incurred over the next 50 years and are relatively stable from period to period as the majority of our proved reserves are already developed. When such amounts are collapsed into a single undiscounted number, as presented in the standardized measure disclosure, it skews the significance of abandonment costs to this line item. We believe a reasonable investor would not view undiscounted cash flows the same way they view discounted cash flows, and that a reasonable investor would consider the timing of when cash is received or paid in utilizing the information included in the individual line items of the Standardized Measure calculation.
Additionally, the future income taxes line item as of December 31, 2020 changes 100% as a result of the corrections to the Standardized Measure. However, this percentage change is misleading, as the total change in income taxes represents less than 2% of the total revised Standardized Measure. Because of net operating loss carryforwards, the Company was estimated to pay an insignificant amount of future income taxes in the original 2020 Standardized Measure calculation. The change in development costs as a result of including abandonment costs brings that expectation to zero, but it does not result in a material change in the Company’s overall estimated future income tax expense.
Standardized Measure Analysis
The changes in the overall Standardized Measure as of December 31, 2019 and 2018 as a result of the error correction are quantitatively immaterial and there are no qualitative factors that would indicate that these errors are material. Including abandonment costs in the Standardized Measure as of December 31, 2020, however, changes the net discounted cash flows by 10%. Although quantitatively more significant as of December 31, 2020, after further analysis the Company has determined that the change in the overall Standardized Measure is also immaterial for the reasons articulated below.
We understand that the Staff has made public comments indicating that one situation in which a quantitatively significant error can be immaterial is when a company has breakeven results. This can occur when events or transactions reduce the denominator used to calculate the percentage impact of an error to an unusually low amount. For example, assume a company historically has reported net income of $1 million but in the current year reports net income of $100 thousand. If there is an error of $10 thousand in the current year it would not necessarily be a material error even though it is 10% of pretax income in the current year. In this situation, it is necessary to evaluate the total mix of information and what a reasonable investor would consider to be material.
The Company believes the impact of its error within the Standardized Measure as of December 31, 2020 is analogous to the break-even results example above. As a result of the abnormally low oil price used to calculate the Standardized Measure as of December 31, 2020, discussed below, the net discounted cash flow amount is 21% and
