Unapproved change orders, amount | $ 79 | $ 40
Unapproved change orders, description | change orders and/or claims that had been included as contract price adjustments on certain contracts that were in the process of being negotiated in the normal course of business. These contract price adjustments represent management's best estimate of additional contract revenues that have earned and that management believes are probable of collection. The amounts ultimately realized upon final acceptance by its customers could be higher or lower than such estimated amounts, which are primarily expected to be billed and collected within one year. |
Deferred financing costs | 9.6 |
Net deferred financing costs | 14.0 | 9.9
Accounting Standards Not Yet Adopted | In July 2013, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2013-11, Income Taxes (Topic 740): Presentation of an Unrecognized Tax Benefit When a Net Operating Loss Carryforward, a Similar Tax Loss, or a Tax Credit Carryforward Exists (a consensus of the FASB Emerging Issues Task Force) (“ASU 2013-11”). ASU 2013-11 provides guidance on the presentation in the financial statements of an unrecognized tax benefit, or a portion of an unrecognized tax benefit, and explains that unrecognized tax benefits should be presented as a reduction to deferred tax assets for net operating loss carryforwards, similar tax losses or tax credit carryforwards. To the extent a net operating loss carryforward, similar tax loss or tax credit carryforward is not available as of the reporting date under the tax law of the applicable jurisdiction, or the tax law of the applicable jurisdiction does not require the entity to use, and the entity does not intend to use, the deferred tax asset for such purpose, the unrecognized tax benefit should be presented in the financial statements as a liability and should not be combined with deferred tax assets. ASU 2013-11 applies to all entities that have unrecognized tax benefits when a net operating loss carryforward, similar tax loss, or tax credit carryforward exists as of the reporting date. ASU 2013-11 is effective prospectively for fiscal years, and interim periods within those years, beginning after December 15, 2013. Retrospective application is permitted. The Company is currently evaluating the potential impact of this ASU on its consolidated financial statements. |
Recently Adopted Accounting Pronouncements | In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income (“ASU 2013-02”). The amendment requires disclosure of information about the amounts reclassified out of accumulated other comprehensive income by component. In addition, disclosure is required, either on the face of the statement where net income is presented, or in the notes, of significant amounts reclassified out of accumulated other comprehensive income by the respective line items of net income, but only if the amount reclassified is required to be reclassified to net income in its entirety in the same reporting period. For other amounts that are not required to be reclassified in their entirety to net income, an entity is required to cross-reference to other disclosures that provide additional detail about those amounts. The new requirements are effective for public companies in interim and annual reporting periods beginning after December 15, 2012. The Company adopted ASU 2013-02 retrospectively as of January 1, 2013. See the Consolidated Statements of Equity and Note 13 - Equity for related disclosures. |

Fair value measurements, significant assumptions | Based on these analyses, the Company estimated the fair values of three of its reporting units using a discounted cash flow methodology, which incorporated management estimates including five-year projections of revenues, operating costs and cash flows considering historical and anticipated future results, general economic and market conditions, as well as the impact of planned business and operational strategies. Management applied a discounted cash flow technique utilizing a terminal value equal to 5.5 times estimated year five EBITDA, which is defined as earnings from continuing operations before interest, taxes, depreciation and amortization. |
