The Agency’s total revenues amounted to $124,361 for 2010–2011, about the same level as the previous year. Almost all of the Agency’s revenue is derived from two sources: penalties (fines) imposed on air carriers and transportation facilities ($92,909), and determining the net salvage value of railway assets during the discontinuance of a railway line ($30,045). All other levels of revenue were marginal for 2010–11.
