(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 based primarily 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 2014, 2013 and 2012, we recorded a benefit within earnings from continuing operations of $14 million, $5 million, and $1 million, respectively, from development in estimated prior years’ self-insured loss reserves for the reasons noted above.
