The LTIP provides for grants of (a)&amp;#160;incentive stock options qualified as such under U.S. federal income tax laws, (b)&amp;#160;stock options that do not qualify as incentive stock options, (c)&amp;#160;stock appreciation rights, (d)&amp;#160;restricted stock awards, (e)&amp;#160;performance awards, (f)&amp;#160;phantom stock, (g)&amp;#160;stock bonuses, (h)&amp;#160;dividend equivalents, and (i)&amp;#160;any combination of such awards. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Stock Options &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On March&amp;#160;23, 2012, the Company granted options to purchase 145,354 shares of the Company's common stock to various employees, including the Company's executive officers. The grant date fair value of these options, using the Black-Scholes-Merton option-pricing model, was approximately $8.42 per share. These options will vest ratably over a three-year period. On January&amp;#160;3, 2012, the Company granted options to purchase 23,734 shares of the Company's common stock to the Company's chief financial officer upon the beginning of his employment with the Company. The grant date fair value of these options, using the Black-Scholes-Merton option-pricing model, was approximately $9.48 per share. These options will vest ratably over a four-year period. The Company issued 6,280 new shares to option holders upon the exercise of vested stock options during the three months ended March&amp;#160;31, 2012. Total intrinsic value of options exercised during the three months ended March&amp;#160;31, 2012 was approximately $0.1&amp;#160;million. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Restricted Stock &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On March&amp;#160;23, 2012, the Company granted restricted stock awards covering 56,980 shares of common stock to various employees, including the Company's executive officers, and 24,024 shares of common stock to eligible members of the Board of Directors. The grant date fair value of the restricted stock was $17.48, which was equal to the closing market price of the Company's common stock on the date of grant. The restricted stock awards granted to employees vest ratably, on an annual basis, over a five-year period with the first tranche vesting on March&amp;#160;23, 2013. The restricted stock awards granted to the eligible members of the Board of Directors vest ratably, on an annual basis, over a three-year period with the first tranche vesting on March&amp;#160;23, 2013. On January&amp;#160;3, 2012, the Company granted restricted stock awards covering 17,562 shares of common stock to two employees, including the Company's chief financial officer. The grant date fair value of the restricted stock was $19.46, which was equal to the closing market price of the Company's common stock on the date of grant. The restricted stock awards vest over a five-year period. On March&amp;#160;24, 2012, a total of 25,248 shares of restricted stock from prior grants became vested and taxable to the individual holder of the restricted stock awards. The Company received 6,186 of those shares as payment for withholding taxes due by holders of the restricted stock awards. The withheld shares were retired. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Performance Awards &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;On March&amp;#160;23, 2012, the Company granted performance stock awards covering 41,755 shares of common stock, at target level, to certain key management personnel, including the Company's executive officers. The grant date fair value of the performance stock awards was $17.48, which was equal to the closing market price of the Company's common stock on the date of grant. The performance stock awards will cliff vest on the third anniversary of the performance period, subject to achievement of certain specified levels of the Company's average return-on-equity ("ROE") over the performance period. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Stock-based Compensation Expense &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company recognizes stock-based compensation expense on a straight-line basis over the vesting period. Stock-based compensation cost is adjusted for changes in estimated and actual forfeitures and also for changes in estimated performance shares that will be earned. The Company recognized stock-based compensation expense of approximately $0.7&amp;#160;million and $0.3&amp;#160;million for the three months ended March&amp;#160;31, 2012 and 2011, respectively, which was included in selling, general and administrative expenses in the accompanying consolidated statements of operations. Stock-based compensation expense for the three months ended March&amp;#160;31, 2011 included a net reduction in expense of $0.2&amp;#160;million for a change in the estimated forfeiture rates for the various awards and a change in the estimated number of performance shares that were expected to be earned. As of March&amp;#160;31, 2012, there was approximately $6.8&amp;#160;million of total unrecognized stock-based compensation cost related to awards granted under the LTIP, net of estimated forfeitures. Total unrecognized compensation cost will be adjusted for any future changes in estimated and actual forfeitures. &lt;/font&gt;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Leases &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company leases real estate, construction equipment and office equipment under operating leases with terms ranging from one to nine years. As of March&amp;#160;31, 2012, future minimum lease payments for operating leases were as follows: $3.5&amp;#160;million for the remainder of 2012, $2.3&amp;#160;million for 2013, $0.9&amp;#160;million for 2014, $0.4&amp;#160;million for 2015, $0.2&amp;#160;million for 2016 and $0.5&amp;#160;million thereafter. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Purchase Commitments for Construction Equipment &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;

&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Insurance and Claims Accruals &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company carries insurance policies, which are subject to certain deductibles, for workers' compensation, general liability, automobile liability and other coverages. The deductible for each line of coverage is between $1.0&amp;#160;million and $1.5&amp;#160;million per claim, depending on whether the claim aggregate has been met. Once a policy's claim aggregate is reached per line of coverage, the deductible for that policy is reduced to $1.0&amp;#160;million per claim. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Certain of the Company's health insurance benefit plans are subject to a $0.1&amp;#160;million deductible for qualified individuals. Losses up to the stop loss amounts are accrued based upon the Company's estimates of the ultimate liability for claims reported and an estimate of claims incurred but not yet reported. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The insurance and claims accruals are based on known facts, actuarial estimates and historical trends. While recorded accruals are based on the ultimate liability, which includes amounts in excess of the stop loss deductible, a corresponding receivable for amounts in excess of the stop loss deductible is included in current assets in the consolidated balance sheets. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Surety Bonds &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In certain circumstances, the Company is required to provide performance bonds in connection with its future performance on contractual commitments. The Company has indemnified its surety for any expenses paid out under these performance bonds. As of March&amp;#160;31, 2012, an aggregate of approximately $899.4&amp;#160;million in original face amount of bonds issued by the surety were outstanding. Our estimated remaining cost to complete these bonded projects was approximately $397.9&amp;#160;million as of March&amp;#160;31, 2012. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Collective Bargaining Agreements &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Many of the Company's subsidiaries' field labor employees are covered by collective bargaining agreements. The agreements require the subsidiaries to pay specified wages, provide certain benefits and contribute certain amounts to multi-employer pension plans. If a subsidiary withdraws from one or more multi-employer pension plans, or if the plans become underfunded, the subsidiary could be assessed liabilities for additional contributions related to the underfunding of these plans. Although the Company has been informed that several of the multi-employer pension plans to which our subsidiaries contribute have been labeled with a "critical" status, the Company is not aware of any potential significant liabilities related to these plans. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Litigation and Other Legal Matters &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company is, from time to time, party to various lawsuits, claims, and other legal proceedings that arise in the ordinary course of business. These actions typically seek, among other things, compensation for alleged personal injury, breach of contract and/or property damages, punitive damages, civil penalties or other losses, or injunctive or declaratory relief. With respect to all such lawsuits, claims and proceedings, the Company records reserves when it is probable that a liability has been incurred and the amount of loss can be reasonably estimated. The Company does not believe that any of these proceedings, separately or in the aggregate, will have a material adverse effect on the Company's financial position, results of operations or cash flows. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company is routinely subject to other civil claims, litigation and arbitration, and regulatory investigations arising in the ordinary course of our present business as well as in respect of our divested businesses. Some of these include claims related to our current services and operations, and asbestos-related claims concerning historic operations of a predecessor affiliate. The Company believes that it has strong defenses to these claims as well as adequate insurance coverage in the event any asbestos-related claim is not resolved in our favor. These claims have not had a material impact on the Company to date and the Company believes that the likelihood that a future material adverse outcome will result from these claims is remote. However, if facts and circumstances change in the future, the Company cannot be certain that an adverse outcome of one or more of these claims would not have a material adverse effect on the Company's financial condition, results of operations, or cash flows. &lt;/font&gt;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company had approximately $0.7&amp;#160;million of total unrecognized tax benefits as of March&amp;#160;31, 2012 and December&amp;#160;31, 2011 which was included in other liabilities in the accompanying consolidated balance sheets. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company's policy is to recognize interest and penalties related to income tax liabilities as a component of income tax expense in the consolidated statements of operations. The amount of interest and penalties charged to income tax expense as a result of the unrecognized tax benefits was less than $0.1&amp;#160;million for each of the three month periods ended March&amp;#160;31, 2012 and 2011. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company is subject to taxation in various jurisdictions. The Company's federal tax returns for 2009 and 2010 are currently under examination by the Internal Revenue Service. The Company's state tax returns remain subject to examination by various state authorities for the years 2007 through 2011. &lt;/font&gt;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;2. Fair Value Measurements &lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company uses the three-tier hierarchy of fair value measurement, which prioritizes the inputs used in measuring fair value based upon their degree of availability in external active markets. These tiers include: Level&amp;#160;1 (the highest priority), defined as observable inputs, such as quoted prices in active markets; Level&amp;#160;2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level&amp;#160;3 (the lowest priority), defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;As of March&amp;#160;31, 2012 and December&amp;#160;31, 2011, the carrying value of the Company's cash and cash equivalents approximated fair value based on Level&amp;#160;1 inputs. The Company determined that the carrying value of revolving borrowings under the credit facility at December&amp;#160;31, 2011, which had short maturities and interest rates that were based upon variable reference rates, approximated fair value based on Level&amp;#160;2 inputs. &lt;/font&gt;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;

&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The Company performs construction services in two business segments: Transmission and Distribution ("T&amp;amp;D"), and Commercial and Industrial ("C&amp;amp;I"). T&amp;amp;D customers include electric utilities, cooperatives and municipalities. The Company provides a broad range of T&amp;amp;D services which includes design, engineering, procurement, construction, upgrade, maintenance and repair services with a particular focus on construction, maintenance and repair throughout the continental United States. The Company also provides C&amp;amp;I electrical contracting services to facility owners and general contractors in the western United States. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Interim Consolidated Financial Information &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The accompanying consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America ("U.S.&amp;#160;GAAP") for interim financial reporting and pursuant to the rules and regulations of the SEC. Certain information and note disclosures typically included in financial statements prepared in accordance with U.S.&amp;#160;GAAP have been omitted in accordance with these rules and regulations. In the opinion of management, the accompanying consolidated financial statements contain all adjustments (consisting of only normal recurring adjustments) necessary to state fairly the financial condition of the Company as of March&amp;#160;31, 2012, and the results of operations, and cash flows for the three months ended March&amp;#160;31, 2012 and 2011. The results of operations for the three months ended March&amp;#160;31, 2012 are not necessarily indicative of the results for the full year or the results for any future periods. The consolidated balance sheet as of December&amp;#160;31, 2011 has been derived from the audited financial statements as of that date. These financial statements should be read in conjunction with the audited financial statements and related notes for the year ended December&amp;#160;31, 2011, included in the Company's annual report on Form&amp;#160;10-K. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Use of Estimates &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;The preparation of financial statements in conformity with U.S.&amp;#160;GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and revenues and expenses during the period reported. Actual results could differ from those estimates. The most significant estimates are related to estimates to complete on contracts, insurance reserves, the accounts receivable reserve, the recoverability of goodwill and intangibles and estimates surrounding stock-based compensation. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Reclassifications &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Certain amounts reported previously have been reclassified to conform to the current year presentation. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Recently Issued Accounting Pronouncements &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;Changes to U.S.&amp;#160;GAAP are typically established by the Financial Accounting Standards Board ("FASB") in the form of accounting standards updates ("ASUs") to the FASB's Accounting Standards Codification ("ASC"). The Company considers the applicability and impact of all ASUs. The Company, based on its assessment, determined that any recent ASUs not listed below are either not applicable to the Company or have minimal impact on our consolidated financial statements. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In December 2011, the FASB issued ASU No.&amp;#160;2011-11, &lt;/font&gt;&lt;font size="2"&gt;&lt;i&gt;Balance Sheet (Topic 210): Disclosures about Offsetting Assets and Liabilities&lt;/i&gt;&lt;/font&gt;&lt;font size="2"&gt;. The update requires entities to disclose information about offsetting and related arrangements of financial instruments and derivative instruments. ASU 2011-11 is effective for annual reporting periods beginning on or after January&amp;#160;1, 2013, and interim periods within those annual periods. The Company currently believes there will be no significant impact of adopting this standard on its consolidated financial statements. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In September 2011, the FASB issued ASU No.&amp;#160;2011-08, &lt;/font&gt;&lt;font size="2"&gt;&lt;i&gt;Intangibles-Goodwill and Other (Topic 350): Testing Goodwill for Impairment.&lt;/i&gt;&lt;/font&gt;&lt;font size="2"&gt; This update was intended to simplify how entities test goodwill for impairment. ASU 2011-08 permits an entity to first assess qualitative factors to determine whether it is "more-likely-than-not" that the fair value of a reporting unit is less than its carrying amount as a basis for determining whether it is necessary to perform the two-step goodwill impairment test described in ASC 350. The "more-likely-than-not" threshold is defined as having a likelihood of more than 50%. ASU 2011-08 was effective for annual and interim goodwill impairment tests performed for reporting periods beginning after December&amp;#160;15, 2011. The Company adopted the provisions of ASU 2011-08 in January 2012 and there was no effect on the Company's financial position, results of operations or cash flows. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In April 2011, the FASB issued ASU No.&amp;#160;2011-04 to ASC 820 which generally converged U.S.&amp;#160;GAAP and International Financial Reporting Standards requirements for fair value measurements and related disclosures. This update became effective for interim and annual reporting periods beginning after December&amp;#160;15, 2011. The adoption of this standard in January 2012 did not have an impact on the Company's consolidated financial statements, and there were no material impacts to the Company's financial statement disclosures. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&lt;b&gt;&lt;i&gt;Proposed Accounting Pronouncements &lt;/i&gt;&lt;/b&gt;&lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In June 2010, the FASB issued an exposure draft, &lt;/font&gt;&lt;font size="2"&gt;&lt;i&gt;Revenue from Contracts with Customers&lt;/i&gt;&lt;/font&gt;&lt;font size="2"&gt;, which would supersede most of the existing guidance on revenue recognition in Accounting Standards Codification ("ASC") Topic 605, &lt;/font&gt;&lt;font size="2"&gt;&lt;i&gt;Revenue Recognition&lt;/i&gt;&lt;/font&gt;&lt;font size="2"&gt;. In November 2011, the FASB re-exposed the draft and the comment period ended in March 2012. As the standard-setting process is still ongoing, the Company is unable to determine the impact this proposed change in accounting will have to our consolidated financial statements at this time. &lt;/font&gt;&lt;/p&gt;
&lt;p style="FONT-FAMILY: times"&gt;&lt;font size="2"&gt;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;&amp;#160;In August 2010, the FASB issued an exposure draft, &lt;/font&gt;&lt;font size="2"&gt;&lt;i&gt;Leases&lt;/i&gt;&lt;/font&gt;&lt;font size="2"&gt;, which would result in significant changes to the accounting requirements for both lessees and lessors in ASC Topic 840, &lt;/font&gt;&lt;font size="2"&gt;&lt;i&gt;Leases&lt;/i&gt;&lt;/font&gt;&lt;font size="2"&gt;. In July 2011, the FASB announced its intention to re-expose the draft which is currently scheduled to re-expose in the first half of 2012. As the standard-setting process is still ongoing, the Company is unable to determine the impact this proposed change in accounting will have in the Company's consolidated financial statements at this time. &lt;/font&gt;&lt;/p&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;&lt;/td&gt;&lt;/tr&gt;&lt;/table&gt;
