(1) Insurance obligations are primarily comprised of self-insured claim liabilities.

We retain a portion of the accident risk under vehicle liability and workers’ compensation insurance programs. Self-insurance accruals are primarily based on actuarially estimated, undiscounted cost of claims, and include claims incurred but not reported. Such liabilities are based on estimates. Historical loss development factors are utilized to project the future development of incurred losses, and these amounts are adjusted based upon actual claim experience and settlements. While we believe the amounts are adequate, there can be no assurance that changes to our estimates may not occur due to limitations inherent in the estimation process. During 2015, we recognized a charge within earnings from continuing operations of $4 million from development of estimated prior years’ self-insured loss reserves for the reasons noted above as well as a settlement of a customer-extended insurance claim. In 2014 and 2013, we recognized benefits within earnings from continuing operations of $14 million and $5 million, respectively, from development of estimated prior years’ self-insured loss reserves for the reasons noted above.
