Our marketable securities are invested in U.S. government treasuries with original maturities ranging in length from 4 months to 12 months. The fair value of our marketable securities are determined using Level 2 inputs (because although these securities are traded, in many cases the market is not active and the year-end valuation is generally based on the last trade of the year, which may be several days prior to December 31).
