Honorable Mayor and Members of the City Council City of Lino Lakes, Minnesota Page 2 Qualitative aspects of accounting practices (Continued) Accounting estimates Accounting estimates are an integral part of the financial statements prepared by management and are based on management's knowledge and experience about past and current events and assumptions about future events. Certain accounting estimates are particularly sensitive because of their significance to the financial statements and because of the possibility that future events affecting them may differ significantly from those expected. The most sensitive estimates affecting the financial statements were: • Management's estimate of the useful lives of capital assets is based on authoritative guidance and past experience. We evaluated the key factors and assumptions used to develop the useful lives of capital assets in determining that it is reasonable in relation to the financial statements taken as a whole. • Management's estimate of the allowance for doubtful accounts is based on collection history of ambulance billings and an analysis of the collectability of individual accounts. • Management's estimate of the amount of the year -end compensated absences payable to employees is based on historical trends and anticipated leave time activity. • Management's estimate of the investments at fair value is based on published market values at December 31, 2012. Financial statement disclosures Certain financial statement disclosures are particularly sensitive because of their significance to financial statement users. There were no particularly sensitive financial statement disclosures. The financial statement disclosures are neutral, consistent, and clear. Difficulties encountered in performing the audit We encountered no significant difficulties in dealing with management in performing and completing our audit. Uncorrected misstatements Professional standards require us to accumulate all misstatements identified during the audit, other than those that are clearly trivial, and communicate them to the appropriate level of management. Management did not identify and we did not notify them of any uncorrected financial statement misstatements. Disagreements with management For purposes of this letter, a disagreement with management is a financial accounting, reporting, or auditing matter, whether or not resolved to our satisfaction, that could be significant to the financial statements or the auditors' report. No such disagreements arose during our audit. Management representations We have requested certain representations from management that are included in the management representation letter dated May 22, 2013.
