I MSLMOORE STEPHENS <br /> LOVELACE teas s .ADVISORS <br /> 1 Our auditors use extensive sampling procedures to obtain satisfactory audit evidence. <br /> ISampling procedures routinely include statistical and non-statistical sampling based upon: <br /> • the overall objective of the test • the nature of the sample population <br /> I • the sample size • the nature of the item(s)being examined <br /> • the anticipated outcome of the sample results • the significance of the results <br /> Ordinarily, the significant portions of the sampling expected to be performed are identified at the onset <br /> I of the engagement and are coordinated with the remaining auditing procedures to produce timely and <br /> efficient results. <br /> We currently expect to perform the following types of sampling: <br /> I <br /> Attribute Sampling - To test the rate of deviation from a prescribed internal control procedure to <br /> determine whether planned reliance on that control is appropriate. In addition to tests of compliance <br /> I with prescribed control procedures, attribute sampling will be used for certain substantive procedures <br /> to test for possible unrecorded transactions and for testing existing account balances. <br /> IVariable Sampling-To reach a conclusion about the adequacy or reasonableness of an account balance. <br /> Examples of areas where we will apply sampling strategies include: <br /> I <br /> • The selection of cash receipts postings to test for • The selection of debt payment transactions to <br /> determination of compliance with related test for timeliness of,and completeness of, <br /> statutory requirements and utility rate schedules payments to paying agents for debt costs and <br /> 1 • CRA transactions fiscal agent fees <br /> • The selection of cash disbursements and payroll • The selection of other transactions to <br /> transactions for compliance testing determine compliance with laws and <br /> I • Journal entries regulations <br /> Extent of Use of EDP Software in the Engagement <br /> I To the extent possible, it is our policy to incorporate the use of Computer-Assisted Audit Techniques <br /> (CAATs) in all phases of our audit. Our Firm understands the efficiencies and effectiveness derived <br /> with the proper use of these audit techniques. We have committed significant Firm resources to <br /> I provide your audit team with the tools and training to use these techniques. Our Firm uses IDEA data- <br /> mining software. This software enables us to take virtually any output file format from your financial <br /> reporting package and convert it into a usable data format for our staff to perform CAATs, such as: <br /> I . Comparison of employee and vendor addresses to identify employees who are also <br /> vendors, <br /> • Analyzing numerical sequences from large populations to identify missing or duplicate <br /> I checks or invoices, <br /> • Sorting payments to identify transactions that fall just under financial control or <br /> contract limits, <br /> 1 • Unexpectedtrends in the number of, or amounts of, payments to vendors, and <br /> • Search for false employees by comparing the human resources database with the <br /> payroll system database. <br /> 1 <br /> 311 <br />
