By contrast, in boom periods the principal concern of steel companies
is with the physical acquisition of iron units in order to produce steel; there is less attention to
cost issues, because any variances in this regard can normally be recovered from the relatively
strong existing markets for finished steel products during such periods. In such an environment,
producers tend to be able to eliminate or at least significantly reduce discounts.
