This ASU provides guidance on financial statement presentation of an unrecognized tax benefit when a net operating loss carryforward, a similar tax loss, or a tax credit carryforward exists. Income tax accounting guidance did not explicitly address how to present unrecognized tax benefits when a company also has net operating losses or tax credit carryforwards. Previously, most companies presented these unrecognized benefits as a liability (i.e., gross presentation), but some presented the liability as a reduction of their net operating losses or tax credit carryforwards (i.e., net presentation). To address this diversity in practice, the FASB issued ASU 2013-11, requiring unrecognized tax benefits to be offset against a deferred tax asset for a net operating loss carryforward, similar tax loss, or tax credit carryforward except when either (1) a net operating loss carryforward, a similar tax loss, or a tax credit carryforward is not available as of the reporting date under the governing tax law to settle taxes that would result from the disallowance of the tax position, or (2) the entity does not intend to use the deferred tax asset for this purpose (provided that the tax law permits a choice). If either of these conditions exists, an entity should present an unrecognized tax benefit in the financial statements as a liability and should not net the unrecognized tax benefit with a deferred tax asset. Synovus adopted the provisions of ASU 2013-11 effective January 1, 2014. However, because prior to adoption Synovus already presented its unrecognized tax benefits as a reduction of its net operating losses, adoption of ASU 2013-11 did not have a significant impact on its consolidated balance sheet.
