As of March 31, 2013, $1.7 million remained available under these grants. In October 2010, we entered into a platform development funding agreement with Vulcan Inc. and its affiliate, which we refer to collectively as Vulcan, pursuant to which we received $20.0 million for our G protein-coupled receptor, or GPCR, program. Of the funds received from Vulcan, we recorded $10.8 million as a reduction of the cost of the intellectual property assets we purchased from Patobios Limited, or Patobios, $994,000 was recorded in equity for the fair value of warrants issued to Vulcan, and the remaining $8.2 million was recorded as deferred revenue.

Also in October 2010, we entered into an agreement with the Life Sciences Discovery Fund Authority, a granting agency of the State of Washington, or LSDF, under which we received a $5.0 million grant award from LSDF that was paid to reimburse us for expenses we incurred and equipment purchases related to our GPCR program. For the three months ended March 31, 2013 and 2012, we have recorded reductions to the Vulcan deferred revenue balance of $970,000 and $712,000, respectively, which has been recognized as revenue on our accompanying consolidated statements of operations and comprehensive loss. As of March 31, 2013, all amounts pertaining to the Vulcan agreement previously recorded as deferred revenue in the accompanying consolidated balance sheets have been recognized as revenue. We recognized all remaining revenue of $624,000 under the LSDF agreement during the first quarter of 2012.
