Future Regulatory Developments Future regulatory developments and actions could affect operations and increase operating costs for the airline industry, including our airline subsidiaries.
See Part I, Item 1A.
Risk Factors - " If we are unable to obtain and maintain adequate facilities and infrastructure throughout our system and, at some airports, adequate Slots, we may be unable to operate our existing flight schedule and to expand or change our route network in the future, which may have a material adverse impact on our operations," "Our business is subject to extensive government regulation, which may result in increases in our costs, disruptions to our operations, limits on our operating flexibility, reductions in the demand for air travel, and competitive disadvantages" and "We are subject to many forms of environmental regulation and may incur substantial costs as a result" for additional information.

In 2013, salaries, wages, and benefits were one of our largest expenses and represented approximately 22% of our operating expenses.

Under the terms of the Plan, employees can choose each year to have up to 20% of their annual compensation specified to purchase the Company's common stock.
Share purchases in any calendar year are limited to the lesser of 1,000 shares or shares with a market value of $25,000.
The purchase price of the stock is 85% of the market price on the day prior to the purchase date.
Under the Plan the Company sold approximately 444,000, 379,000 and 493,000 shares to employees during the years ended September 30, 2007, September 30, 2006 and September 30, 2005, respectively.

Stock Bonus Plan The Company's 2007 Stock Bonus Plan authorizes the Company to issue up to 3,000,000 restricted shares to officers and certain other employees in lieu of cash for 10% to 20% of annual bonus amounts in excess of $250,000.
The 2007 Plan was established to replace, on substantially the same terms and conditions, the 1999 Plan.
The determination of the number of shares to be granted may encompass a discount from market value at the discretion of the Compensation Committee of the Board of Directors.
Under the plan the shares are generally restricted for a three year period, during which time the shares are forfeitable in the event of voluntary termination other than for death, disability or retirement.
The compensation cost is recognized over the three-year vesting period based on the market value of the shares on the date of grant.
