The combined company must control its costs to remain profitable.
We base our cost structure on historical and expected levels of demand for our products and services. A decline in the demand for the combined companys products and services may reduce the combined companys revenues without a corresponding decline in its expenses since the combined company may not be able to adjust its cost structure on a timely basis. The combined companys failure to achieve its goals on cost savings may have an adverse impact on the combined companys results of operations.
