     The total deferred tax asset was $8.3 million and $9.4 million at June 30, 2013 and December 31, 2012, respectively. Although management considers our valuation allowance and loss contingency as of June 30, 2013 and December 31, 2012 adequate, material changes in these amounts may occur in the future based on tax audits and changes in legislation.
