| Stock-based Compensation, Equity Grants, and Warrants                         | Stock-based compensation, equity grants, and warrantsStock-based compensation expense All grants of equity are presently made under the 2006 Long Term Incentive Plan.  As of September 30, 2014, 0.9 million shares remained available for grant under the Plan.  Options issued under the Plan are designated as either an incentive stock or a non-statutory stock option.  No option may be granted with a term of more than 10 years from the date of grant.  Option awards may depend on achievement of certain performance measures determined by the Compensation Committee of our Board. Shares issued upon option exercise are newly issued shares.Stock-based compensation expense, shown in the table below, is recorded in general and administrative expenses included in our statement of operations:    (in thousands)   Year Ended Ref September 30,   2014 2013DLH employees $363 $140Non-employee directors(a) 109 54Warrants to consultants(b) — 12Total compensation expense  $472 $206Ref (a): Equity grants of restricted stock to non-employee directors, in accordance with DLH compensation policy for non-employee directors.

The compensation expense for that portion of awards has been based on the grant-date fair value of those awards as calculated for recognition purposes under applicable guidance. For options that vest based on the Company’s common stock achieving and maintaining defined market prices, the Company values the awards with a binomial model that utilizes various probability factors and other criterion in establishing fair value of the grant. The related compensation expense is recognized over the derived service period determined in the valuation. This expense is expected to be recognized over the next 2.8 years, with a weighted average life of 1.2 years.Ref (b):  Unrecognized stock expense related to prior years equity grants of restricted stock to non-employee directors, based on performance criteria, in accordance with DLH compensation policy for non-employee directors.
