City of Lino Lakes, Minnesota Management Report, Page 36 There are inherent limitations that should be recognized in considering the potential effectiveness of any system of internal accounting control. In the parformance of most control procedures, errors can result from misunderstanding of instructions, mistakes of judgment, carelessness, or other personal factors. Control procedures whose effectiveness depends upon segregation of duties can be circumvented by collusion. Similarly, control procedures can be circumvented intentionally by management either with respect to the execution and recording of transactions or with respect to the estimates and judgments required in the pre- - paration of financial statements. Also, projection of any evaluation of the system to future periods is subject to the risk that the procedures may become inadequate because of changes in con- _ ditions and that the degree of compliance with the procedures may deteriorate. Our study and evaluation made for the limited purpose described in the first paragraph would not necessarily disclose all material weaknesses in the system. Accordingly, we do not express an opinion on the system of internal accounting control of the City of Lino Lakes taken as a whole. However, our study and eva- -, luation disclosed that a substantial portion of the accounting processes are per- formed by a single employee. Ideal conditions call for segregation of duties to establish a system of internal testing of procedures performed. Additionally, our evaluation disclosed that the City does not maintain a system of control over INNOIN fixed assets. These conditions are common to cities of this size. Any modifica- tion of internal controls in these areas must be viewed from a cost /benefit perspective. These conditions were considered in determining the nature, timing, and extent of the audit tests to be applied in our examination of the December 31, 1985 financial statements, and this report does not affect our report on the financial statements dated February 3, 1986. This report is intended solely for the use of the City of Lino Lakes and should not be used for any other purpose. Computer System The City has purchased a computer system in 1985. The City is implementing a system for water and sewer customer billings and collections in 1986. The City compared the results of the 4th quarter 1985 computer billing with its manual system and will be using the computerized system for all future utility billings. In 1986 the City will be implementing a computerized payroll system as well as its general ledger system.
