Operating Expenses
## Table 3 ##
Operating expenses increased $348 million in 2012 versus 2011.
Depreciation, wage and benefit inflation, higher fuel prices and volumerelated trucking services purchased by our logistics subsidiaries, contributed to higher expenses during the year.
Efficiency gains, volume related fuel savings (2% fewer gallons of fuel consumed) and $38 million of weather related expenses in 2011, which favorably affects the comparison, partially offset the cost increase.
Operating expenses increased $1.8 billion in 2011 versus 2010.
Our fuel price per gallon rose 36% during 2011, accounting for $922 million of the increase.
Wage and benefit inflation, volume-related costs, depreciation, and property taxes also contributed to higher expenses.
Expenses increased $20 million for costs related to the flooding in the Midwest and $18 million due to the impact of severe heat and drought in the South, primarily Texas.
Cost savings from productivity improvements and better resource utilization partially offset these increases.
A $45 million one-time payment relating to a transaction with CSX Intermodal, Inc (CSXI) increased operating expenses during the first quarter of 2010, which favorably affects the comparison of operating expenses in 2011 to those in 2010.
Compensation and Benefits – Compensation and benefits include wages, payroll taxes, health and welfare costs, pension costs, other postretirement benefits, and incentive costs.
Expenses in 2012 were essentially flat versus 2011 as operational improvements and cost reductions offset general wage and benefit inflation and higher pension and other postretirement benefits.
In addition, weather related costs increased these expenses in 2011.
A combination of general wage and benefit inflation, volume-related expenses, higher training costs associated with new hires, additional crew costs due to speed restrictions caused by the Midwest flooding and heat and drought in the South, and higher pension expense drove the increase during 2011 compared to 2010.
Fuel – Fuel includes locomotive fuel and gasoline for highway and non-highway vehicles and heavy equipment.
Higher locomotive diesel fuel prices, which averaged $3.22 per gallon (including taxes and transportation costs) in 2012, compared to $3.12 in 2011, increased expenses by $105 million.
Volume, as measured by gross ton-miles, decreased 2% in 2012 versus 2011, driving expense down.
The fuel consumption rate was flat year-over-year.
Higher locomotive diesel fuel prices, which averaged $3.12 (including taxes and transportation costs) in 2011, compared to $2.29 per gallon in 2010, increased expenses by $922 million.
