Income Taxes	10. Income Taxes The effective tax rate for the three months ended March 31, 2017 was 0.1%, compared to 0.2% for the same period in 2016. Should we generate taxable income in 2017, we expect that the taxable income will be substantially offset by the utilization of net operating losses or other deferred tax assets. The difference between the consolidated effective income tax rate and the U.S. federal statutory rate is primarily attributable to a change in valuation allowance against net deferred tax assets.
