(1) | Transferred from other accounts includes employee contributions made to the medical and dental self-insurance plans.
(2) | Deductions represent write-offs, lease termination payments, insurance claim payments during the period and net foreign currency translation adjustments.
(3) | Self-insurance accruals include vehicle liability, workers’ compensation, property damage, cargo and medical and dental, which comprise our self-insurance programs. Amounts charged to earnings include developments in prior years' selected loss development factors which benefited earnings by $9 million in 2017 and charged earnings by $9 million and $4 million in 2016 and 2015, respectively. Prior year presentation of self-insurance accruals has been revised to reflect amounts charged to earnings and deductions consistent with current year presentation.
