For definite quantity contracts without options, the evaluated bid price is the total bid price, as adjusted for any price-related factors identified in the solicitation.

Options involve the probability of whether and when the options will be exercised. These situations may result in unbalanced bids (see FAR 15.404-1(g)), leading to inaccurate evaluation of the projected cost and award to other than the most advantageous bid. To avoid unbalanced bids, GSA has two preferred methods for evaluating bids for aggregate awards: weight factors and price list.</p>
