For IS -related controls that we deem to be ineffectively designed or not operating as intended, we will gather <br />sufficient evidence to support appropriate findings and will provide recommendations to improve internal <br />controls. For those IS controls that we deem to be effectively designed, we will perform testing to determine if <br />they are operating as intended through a combination of procedures, including observation, inquiry, inspection, <br />and re -performance. <br />Phase 4: Testing & Analysis <br />The extent of our substantive testing will be based on results of our internal control tests. It has been our <br />experience that governmental entities, like the City, often have a system of internal controls that, with <br />appropriately designed tests and correlation to account balances, can be used to limit the extent of account <br />balance substantiation testing. <br />Audit sampling will be used only in those situations where it is the most effective method of testing. Before <br />deciding to sample, we will consider all possible approaches and audit techniques. Items where, in our <br />judgment, acceptance of some sampling risk is not justified will be examined 100 percent. These may include <br />unusual items or items for which potential misstatements could individually equal or exceed tolerable error. <br />After identifying individually significant or unusual items, we will decide on the audit approach for the remaining <br />balance of items by considering tolerable error and audit risk. This may include (1) testing a sample of the <br />remaining balance; (2) lowering the previously determined threshold for individually significant items to increase <br />the percent of coverage of the account balance; or (3) applying analytical procedures to the remaining balance. <br />When we elect to sample balances, we will use IDEA to efficiently control and select our samples. <br />Our work papers during this phase will clearly document our work as outlined in our audit programs. We will <br />also provide the City with status reports during the audit fieldwork. As in all phases of the audit, we will be in <br />communication with the City to determine that all identified issues are resolved in a timely manner. We will also <br />hold a final exit conference with the City to summarize the results of our fieldwork and review significant <br />findings. <br />Reports to management will include oral and/or written reports regarding: <br />• Independent auditors' report <br />• Management letter <br />• Written communication to those charged with governance, which includes the following areas: <br />— Our responsibility under auditing standards generally accepted in the United States of America <br />— Changes in significant accounting policies ortheir application <br />— Unusual transactions <br />— Management judgments and accounting estimates <br />— Significant audit adjustments <br />— Other information in documents containing the audited financial statements <br />— Disagreements with the City <br />— The City's consultations with other accountants <br />— Major issues discussed with management prior to retention <br />— Difficulties encountered in performing the audit <br />— Fraud or illegal acts <br />Once the final review of working papers and financial statements are completed — a process that actually starts <br />while the fieldwork is in process — our opinion, the financial statements, and management letter will be issued. <br />
