Income Tax Disclosure [Abstract] |
Income Taxes | Income Taxes In July 2013, the FASB issued ASU 2013-11, Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists ("ASU 2013-11"), to provide guidance on the presentation of unrecognized tax benefits. ASU 2013-11 requires an entity to present an unrecognized tax benefit, or a portion of an unrecognized tax benefit, as a reduction to a deferred tax asset for a net operating loss carryforward, a similar tax loss, or a tax credit carryforward with certain limited exceptions. ASU 2013-11 was effective for annual reporting periods beginning on or after December 15, 2013 and interim periods within those annual periods. The Company adopted this guidance in the quarter ended December 31, 2014 with no significant impact to our financial statements. In the normal course of business, we are subject to audits by federal and state tax authorities regarding various tax liabilities. Our federal income tax returns for fiscal years 2011 through 2012 were agreed to with the IRS Appeals Office and approved by the Joint Committee on Taxation in the first quarter of fiscal year 2015. Certain state income tax returns for various fiscal years are under routine examination. The statute of limitations for our major tax jurisdictions remains open for examination for our fiscal year 2007 and subsequent years. As of March 31, 2015, it is reasonably possible that up to $3.2 million of our total uncertain tax positions will reverse within the next twelve months, primarily due to the expiration of statutes of limitation in various jurisdictions. As of both March 31, 2015 and September 30, 2014, we had $0.4 million of accrued interest and penalties related to our unrecognized tax benefits. We experienced an “ownership change” as defined in Section 382 of the Internal Revenue Code (Section 382) as of January 12, 2010. Section 382 contains rules that limit the ability of a company that undergoes an “ownership change” to utilize its net operating loss carryforwards (NOLs) and certain built-in losses or deductions recognized during the five-year period after the ownership change to offset future taxable income. Therefore, our ability to utilize our pre-ownership change NOLs and recognize certain built-in losses or deductions is limited by Section 382 to an estimated maximum amount of approximately $11.4 million ($4 million tax-effected) annually. Certain deferred tax assets are not subject to any limitation imposed. Due to the Section 382 limitation and the maximum carryforward period of our NOLs, we will be unable to fully recognize certain deferred tax assets. As future economic conditions unfold, we will be able to confirm that certain deferred tax assets will not provide any future tax benefit. At such time, we will remove any applicable deferred tax asset and corresponding valuation allowance. Accordingly, a portion of our $477.1 million of total gross deferred tax assets, of which a significant amount relates to accrued losses on our inventory, may be unavailable due to the limitation imposed by Section 382. As of March 31, 2015, we estimate that between $7.9 million and $40.9 million may be unavailable due to our Section 382 limitation. As a result, upon the resumption of sustained profitability and reversal of our valuation allowance, we estimate that between $392.7 million and $425.6 million of our net deferred tax assets may be available to us for the reduction of future cash taxes. The actual realization of our deferred tax assets is difficult to predict and will be dependent on future events. Considering the limitation imposed by Section 382, the table below depicts the classifications of our deferred tax assets as of March 31, 2015:
(In thousands) | March 31, 2015
Deferred tax assets: |
Subject to annual limitation | $ | 102,207 |
Generally not subject to annual limitation | 333,959 |
Certain components likely to be subject to annual limitation | 40,905 |
Total deferred tax assets | 477,071 |
Deferred tax liabilities | (43,496 | )
Net deferred tax assets before valuation allowance | 433,575 |
Valuation allowance | (433,529 | )
Net deferred tax assets | $ | 46 |
Based upon an evaluation of all available evidence, we established a valuation allowance for substantially all of our deferred tax assets during our fiscal 2008. As of March 31, 2015, we continued our evaluation of whether the valuation allowance against our deferred tax assets was still required. We considered positive evidence including evidence of recovery in the housing markets where we operate, the prospects of continued profitability and growth, a strong backlog and sufficient balance sheet liquidity to sustain and grow operations. Although the Company’s performance and current positioning is bringing it closer to a conclusion that a valuation allowance is no longer needed, further evidence of sustained profitability is needed to reverse our valuation allowance against our deferred tax assets. Therefore, based upon all available positive and negative evidence, we concluded a valuation allowance is still needed for substantially all of our gross deferred tax assets at March 31, 2015. The Company's deferred tax asset valuation allowance was $433.5 million and $445.2 million as of March 31, 2015 and September 30, 2014, respectively. In future periods, we expect to reduce all or a portion of our valuation allowance, generating a non-cash tax benefit, if sufficient positive evidence is present indicating that it is more likely than not that a portion or all of our deferred tax assets will be realized. Changes in existing tax laws could also affect actual tax results and the valuation of deferred tax assets over time.
