The services provided by CPA Firms must be responsive to changes in the environment, which is affected by developments in information technology, the increasing complexity of tax laws and regulations, greater demands by the public for new types of information and CPA assurances on such information, the increasing need of many clients for advisory services, and a host of other factors.

If the public accounting profession as a whole, and Rosenbaum, Rollins & Olah, P.C. in particular, are to meet the legitimate and changing needs of clients and the public, arbitrary restrictions on the services provided are not appropriate. However, Rosenbaum, Rollins & Olah, P.C. as a matter of policy, will undertake only engagements that we believe we can perform with competence, that will be useful to our clients or to appropriate third parties, that will not impair our independence in fact or appearance when we also provide review services to the client involved, and that will help attract and retain the personnel we need to provide the knowledge base essential to maintain our ability to serve our clients and the public in a professional manner. In evaluating proposed engagements, as well as the way we inform clients and others of our capabilities, we consider whether such engagements will lessen public confidence in our independence, integrity, and objectivity in the performance of the review function or in our commitment to that function.
