INSURANCE

We use a combination of insured and self-insurance programs to cover workers’ compensation, general liability, automobile liability, property damage, and other insurable risks. For the majority of these insurance programs, we retain the initial $1.0 million of exposure on a per-occurrence basis, either through deductibles or self-insured retentions. Beyond the retained exposures, we have varying primary policy limits ranging between $1.0 million and $5.0 million per occurrence. To cover general liability and automobile liability losses above these primary limits, we maintain commercial umbrella insurance policies that provide aggregate limits of $200.0 million. Our insurance policies generally cover workers’ compensation losses to the full extent of statutory requirements. Additionally, to cover property damage risks above our retained limits, we maintain policies that provide per occurrence limits of $75.0 million.

The adequacy of our reserves for workers’ compensation, general liability, automobile liability, and property damage insurance claims is based upon known trends and events and the actuarial estimates of required reserves considering the most recently completed actuarial reports. We use all available information to develop our best estimate of insurance claims reserves as information is obtained.

During the three months ended January 31, 2016, an actuarial review was performed for the majority of our casualty insurance programs that indicated unfavorable developments in our estimates of ultimate losses related to certain general liability, workers’ compensation, and automobile liability claims, as described below. This review considered all changes made to claims reserves and claim payment activity for the period commencing May 1, 2015 and ending October 31, 2015 (the “Review Period”). We performed this review for all policy years in which open claims existed.

For our general liability program, claim frequency was generally consistent with our expectations. However, the actuarial review identified adverse developments in prior year claims. The adverse developments can be largely attributed to increases in the projected costs to resolve several high exposure claims within our retained limits. Also contributing to the increase in projected estimates was a higher than expected average incurred cost for our less severe claims observed during the Review Period.

Our workers’ compensation estimate of ultimate losses was negatively impacted by increases in projected costs for a significant number of prior year claims in New York. These claims have been impacted by increases in statutory benefits and a slowing of claims closures observed during the Review Period. In California, we experienced increases in severity of claims and in frequency of claims beyond that previously projected.

For our automobile liability program, the increase in the projected estimates was primarily associated with significant claim reserve adjustments for a small population of high exposure claims within the 2013 policy year. Also contributing to the increase in projected estimates was an increase in claims frequency in the 2015 policy year observed during the Review Period.

As a result of these developments in our casualty insurance programs, we increased our reserves for known claims as well as our estimate of the loss amounts associated with incurred but not reported (“IBNR”) claims. As a result of this actuarial review, we increased our reserves for claims related to prior periods by $6.0 million at January 31, 2016. As we continue to see a similar trend in adverse developments, we increased our reserves by an additional $6.0 million, resulting in a total increase to our reserves for claims related to prior periods of $12.0 million at April 30, 2016.

During the third quarter of 2016, we expect to complete comprehensive actuarial evaluations for our significant insurance programs using recent claims data. We will continue to monitor claims developments, which may result in further adjustments to our reserves.

We are also self-insured for certain employee medical and dental plans. We retain up to $0.4 million of exposure on a per-participant, per-year basis with respect to claims under our medical plan.

At April 30, 2016 and October 31, 2015, we had insurance claim reserves totaling $394.8 million and $387.4 million, respectively, which include $7.5 million and $8.1 million in reserves, respectively, related to our medical and dental self-insured plans. At April 30, 2016 and October 31, 2015, we also had insurance recoverables, which we include in “Other current assets” and “Other noncurrent assets” on the accompanying unaudited consolidated balance sheets, totaling $66.0 million and $65.9 million, respectively.
