Self-Insurance	9 Months Ended
Jul. 31, 2012
Self-Insurance	7. Self-Insurance The Company self-insures certain insurable risks, such as workers’ compensation, general liability, automobile and property damage. The Company periodically performs a thorough review, with the assistance of external professionals, of its estimate of the ultimate cost for self-insurance reserves. As part of this evaluation, the Company reviews the status of existing and new claims and coordinates this review with third-party claims administrators. The Company compares actual trends to expected trends and monitors claims developments. The third-party claims administrators that manage the claims for the Company project their estimates of the ultimate cost for each claim based upon known factors related to the management of the claims, legislative matters, and case law. After reviewing the findings with the Company, the specific case reserves estimated by the third-party claims administrators are provided to an actuary who assists the Company in projecting an actuarial estimate of the overall ultimate cost for self-insurance, which includes the case reserves plus an actuarial estimate of reserves required for additional developments, including “incurred but not reported” claim costs. The independent third-party’s actuarial estimate of the reserves is reviewed by management and forms the basis for management’s best estimate of the reserves, as recorded in the Company’s financial statements. Although the Company engages third-party experts to assist in estimating appropriate self-insurance reserves, the determination of those reserves is dependent upon significant actuarial judgments that have a material impact on the Company’s reserves. The interpretation of trends requires knowledge of many factors, which include, among others, changes in regulatory requirements, safety programs, and/or claims handling practices. If analyses of losses suggest that the frequency or severity of claims incurred has changed, the Company would be required to record increases or decreases in expenses for self-insurance liabilities. Actuarial evaluations completed during the three months ended July 31, 2012, covering certain self-insurance programs of the Company, resulted in an increase in the self-insurance reserve of $9.7 million, substantially all of which pertains to prior year claims. This adjustment was recorded in the Corporate segment. The increase was primarily related to higher than expected losses in general liability and workers’ compensation claims for years prior to fiscal 2012. During the fourth quarter of 2012, actuarial reports are expected to be completed for the Company’s remaining programs using recent claims data and may result in additional adjustments to earnings during that period. At July 31, 2012, the Company had $96.9 million in standby letters of credit (primarily related to its workers’ compensation, general liability, automobile, and property damage programs), $31.7 million in restricted insurance deposits, and $211.1 million in surety bonds (of which $35.1 million supported insurance claim liabilities). At October 31, 2011, the Company had $97.0 million in standby letters of credit, $36.0 million in restricted insurance deposits, and $231.5 million in surety bonds (of which $30.9 million supported insurance claim liabilities).
