NOTE: This revised FAA-5100-127 (7 April 2010) reflects data based on definition clarifications in accordance
with generally accepted accounting principles that were approved by the Office of Management and Budget (OMB).
A number of Airports filed before the OMB clarifications went into effect, or submitted their FAA-5100-127 as
definitions were being modified prior to 7 April 2010. Therefore, we caution that data may not be comparable
between airports or in total until after a full 12 months of fiscal year data has been submitted (7 April 2011).
