Income taxes
We are subject to income taxes in the United States, and in several states and 
foreign jurisdictions in which we operate. We account for income taxes according 
to Statement of Financial Accounting Standards No. 109, “Accounting for Income
Taxes” (“SFAS 109”). SFAS 109 requires the recognition of deferred tax assets, net
of applicable reserves, related to net operating loss carryforwards and certain 
temporary differences. The standard requires recognition of a future tax benefit 
to the extent that realization of such benefit is more likely than not. Otherwise, 
a valuation allowance is applied.
