All-in Sustaining Costs N Current GAAP measures used in the mining industry, such as cost of goods sold, do not capture all of the expenditures incurred to discover, develop and sustain production. Therefore, Newmont calculates All-In Sustaining Costs ("AISC") based on the definition published by the World Gold Council. The World Gold Council is a market development organization for the gold industry comprised of and funded by gold mining companies around the world and a regulatory organization. AISC is a metric that expands on GAAP measures, such as cost of goods sold, and non-GAAP measures, such as costs applicable to sales per ounce, to provide visibility into the economics of our mining operations related to expenditures, operating performance and the ability to generate cash flow from our continuing operations. We believe that AISC is a non-GAAP measure that provides additional information to management, investors and others that aids in the understanding of the economics of our operations and performance compared to other producers and provides investors visibility by better defining the total costs associated with production. AISC amounts are intended to provide additional information only and do not have any standardized meaning prescribed by GAAP and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with GAAP. The measures are not necessarily indicative of operating profit or cash flow from operations as determined under GAAP. Other companies may calculate these measures differently as a result of differences in the underlying accounting principles, policies applied and in accounting frameworks such as in IFRS, or by reflecting the benefit from selling non-gold metals as a reduction to AISC. Differences may also arise related to definitional differences of sustaining versus development (i.e. non- sustaining) activities based upon each company's internal policies. The following disclosure provides information regarding the adjustments made in determining the All-In Sustaining Costs measure: Costs applicable to sales. Includes all direct and indirect costs related to current production incurred to execute the current mine plan. We exclude certain exceptional or unusual amounts from CAS, such as significant revisions to recovery amounts. CAS includes by-product credits from certain metals obtained during the process of extracting and processing the primary ore-body. CAS is accounted for on an accrual basis and excludes Depreciation and amortization and Reclamation and remediation, which is consistent with our presentation of CAS on the Consolidated Statements of Operations. In determining AISC, only the CAS associated with producing and selling an ounce of gold is included in the measure. Therefore, the amount of gold CAS included in AISC is derived from the CAS presented in the Company's Consolidated Statements of Operations less the amount of CAS attributable to the production of other metals. The other metals' CAS at those mine sites is disclosed in Note 3 of the Consolidated Financial Statements. The allocation of CAS between gold and other metals is based upon the relative sales value of gold and other metals produced during the period. Reclamation costs. Includes accretion expense related to reclamation liabilities and the amortization of the related ARC for the Company's operating properties. Accretion related to the reclamation liabilities and the amortization of the ARC assets for reclamation does not reflect annual cash outflows but are calculated in accordance with GAAP. The accretion and amortization reflect the periodic costs of reclamation associated with current production and are therefore included in the measure. The allocation of these costs to gold and other metals is determined using the same allocation used in the allocation of CAS between gold and other metals. Advanced projects, research and development and exploration. Includes incurred expenses related to projects that are designed to sustain current production and exploration. We note that as current resources are depleted, exploration and advanced projects are necessary for us to replace the depleting reserves or enhance the recovery and processing of the current reserves to sustain production at existing operations. As these costs relate to sustaining our production, and are considered a continuing cost of a mining company, these costs are included in the AISC measure. These costs are derived from the Advanced projects, research and development and Exploration amounts presented in the Consolidated Statements of Operations less incurred expenses related to the development of new operations, or related to major projects at existing operations where these projects will materially benefit the operation in the future. The allocation of these costs to gold and other metals is determined using the same allocation used in the allocation of CAS between gold and other metals. We also allocate these costs incurred at the Other North America, Other Australia and Corporate and Other locations using the proportion of CAS between gold and other metals. General and administrative. Includes costs related to administrative tasks not directly related to current production, but rather related to supporting our corporate structure and fulfilling our obligations to operate as a public company. Including these expenses in the AISC metric provides visibility of the impact that general and administrative activities have on current operations and profitability on a per ounce basis. We allocate these costs to gold and other metals at the Other North America, Other Australia and Corporate and Other locations using the proportion of CAS between gold and other metals. Other expense, net. For Other expense, net we include care and maintenance costs relating to direct operating costs incurred at the mine sites during the period that these sites were temporarily placed into care and maintenance in response to the COVID-19 pandemic and exclude certain exceptional or unusual expenses, such as restructuring, as these are not indicative to sustaining our current operations. Furthermore, this adjustment to Other expense, net is also consistent with the nature of the adjustments made to Net income (loss) attributable to Newmont stockholders as disclosed in the Company's non-GAAP financial measure Adjusted net income (loss). The allocation of these costs to gold and other metals is determined using the same allocation used in the allocation of CAS between gold and other metals. Treatment and refining costs. Includes costs paid to smelters for treatment and refining of our concentrates to produce the salable metal. These costs are presented net as a reduction of Sales on the Consolidated Statements of Operations. The allocation of these costs to gold and other metals is determined using the same allocation used in the allocation of CAS between gold and other metals. Sustaining capital and finance lease payments. We determined sustaining capital and finance lease payments as those capital expenditures and finance lease payments that are necessary to maintain current production and execute the current mine plan. We determined development (i.e. non-sustaining) capital expenditures and finance lease payments to be those payments used to develop new operations or related to projects at existing operations where those projects will materially benefit the operation and are excluded from the calculation of AISC. The classification of sustaining and development capital projects and finance leases is based on a systematic review of our project portfolio in light of the nature of each project. Sustaining capital and finance lease payments are relevant to the AISC metric as these are needed to maintain the Company's current operations and provide improved transparency related to our ability to finance these expenditures from current operations. The allocation of these costs to gold and other metals is determined using the same allocation used in the allocation of CAS between gold and other metals. We also allocate these costs incurred at the Other North America, Other Australia and Corporate and Other locations using the proportion of CAS between gold and other metals.
