Even if sales do not recover the variable cost and the avoidable portion of fixed cost the firm still may be better off operating rather than temporarily closing the facility. Closing a facility and subsequently reopening it is a costly process. The shutdown can entail certain maintenance procedures to preserve machinery and buildings during the period of inactivity (such as rust inhibitors, dust covers, and security equipment the shutdown also can entail legal expenditures and employee maintenance pay. During the shutdown period, some employees will probably be lost (those who decide not to wait until the facility is reopened to go back to work), in which case the investment in training those employees will be lost. The morale of other employees, as well as community goodwill, may be adversely affected, and recruiting and training replacement workers when the facility is later reopened will to costs. Although difficult to quantify, the loss of established market share is also a factor to be considered. When a company leaves a market for a while, its customers tend to forget about the company's product. As a consequence, reentering the market at a later time will probably require re-educating consumers about the company's product. These shutdown costs should be weighed against losses from continued operations.
