Cleverrox (and others interested in this issue), re tax rates and valuation losses.
I'll use another familiar stock: MDF
From their last 10Q:
INCOME TAXES
The Company accounts for income taxes pursuant to Statement of Financial Accounting Standards No. 109, “Accounting for Income Taxes” (“SFAS 109”), which requires income taxes to be accounted for under the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based upon differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in earnings in the period that includes the enactment date. A valuation allowance is established when it is more likely than not that some or all of the deferred tax assets will not be realized.
SFAS No. 109 requires a valuation allowance to reduce the deferred tax assets reported if, based on the weight of the evidence, it is more likely than not that some portion or all of the deferred tax assets will not be realized. After consideration of all the evidence, both positive and negative (including, among others, projections of future taxable income, current year net operating loss carryforward utilization and the Company’s profitability in recent years), the Company determined that future realization of its deferred tax assets was more likely than not and, accordingly, eliminated the valuation allowance against its deferred tax assets as of December 31, 2004. In the event it is determined that the Company would not be able to realize all or part of its net deferred tax assets in the future, an adjustment to record a deferred tax asset valuation allowance would be charged to income in the period such determination would be made. Changes in deferred tax assets are reflected in the “Income Taxes” expense line of the Company’s Condensed Consolidated Statements of Operations.

Also, looking at MDF's cash flow statement, it looks like they paid no taxes at all, after reducing the deferred tax asset and using tax benefits assoc with stock option exercises.
