Due to the variability of annual mine amortization related to the timing of pit openings, amortization is adjusted for a normalized mine amortization based on a 5-year average. Internally, we review the results of operations without the impact of these costs and adjustments in order to assess the profitability from ongoing operations. Debt-to-capitalization is our total debt divided by net cash (debt) plus shareholders’ equity. Net cash (debt) is a non-GAAP financial measure calculated by A-11 subtracting total outstanding debt from our cash & cash equivalents. We are providing this information because we believe it is more indicative of our overall financial position. It is also a measure our management uses to assess financing and other decisions.
