The Company considers debt securities with maturities of three months or less from the purchase date to be cash equivalents. Interest is recorded when earned.

As of September 30, 2013, remaining maturities of marketable debt securities ranged from October 2013 to February 2016, with a weighted-average remaining maturity of approximately 14 months.
