Equity [Abstract] |
Equity | EQUITY: Exchangeable Shares and Series F and Series G Preferred Stock In connection with certain Canadian acquisitions, the former owners of the acquired companies received exchangeable shares of certain Canadian subsidiaries of Quanta, which may be exchanged at the option of the holders for Quanta common stock on a one-for-one basis. The holders of exchangeable shares can make an exchange only once in any calendar quarter and must exchange a minimum of either 50,000 shares or, if less, the total number of remaining exchangeable shares registered in the name of the holder making the request. Additionally, in connection with two of such acquisitions, Quanta issued one share of Quanta Series F preferred stock and one share of Quanta Series G preferred stock (the Preferred Stock) to voting trusts on behalf of the respective holders of the exchangeable shares issued in such acquisitions. Each share of the Preferred Stock provides the holders of such exchangeable shares voting rights in Quanta common stock equivalent to the number of exchangeable shares outstanding. The holders of exchangeable shares associated with the Preferred Stock have rights equivalent to Quanta common stockholders with respect to voting, dividends and other economic rights. The holders of exchangeable shares not associated with the Preferred Stock have rights equivalent to Quanta common stockholders with respect to dividends and other economic rights but do not have voting rights. During the three months ended June 30, 2017 and 2016, no exchangeable shares were exchanged for Quanta common stock. During the six months ended June 30, 2017 and 2016, 2.5 million and no exchangeable shares were exchanged for Quanta common stock. As of June 30, 2017, both shares of the Preferred Stock remained outstanding and 4.0 million exchangeable shares remained outstanding, of which 3.9 million were associated with the Preferred Stock. Treasury Stock Shares withheld for tax withholding obligations Under the stock incentive plans described in Note 9, the tax withholding obligations of employees upon vesting of restricted stock, RSUs and performance units settled in common stock are typically satisfied by Quanta making such tax payments and withholding the number of vested shares having a value on the date of vesting equal to the tax withholding obligation. For the settlement of these employee tax liabilities, Quanta withheld 0.5 million and 0.4 million shares of Quanta common stock during the six months ended June 30, 2017 and 2016, with a total market value of $17.8 million and $7.2 million. These shares and the related costs to acquire them were accounted for as adjustments to the balance of treasury stock. Notional amounts recorded related to deferred compensation plans For RSUs and performance units that vest but the settlement of which are deferred under Quanta’s deferred compensation plans, Quanta records an amount to treasury stock and an offsetting amount to APIC. No shares are recorded as treasury stock at vesting as the shares of Quanta common stock associated with deferred equity awards are not issued. Upon settlement of the deferred equity awards and issuance of the associated Quanta common stock, the original accounting entry is reversed. The net amounts recorded to treasury stock related to the deferred compensation plans during the three months ended June 30, 2017 and 2016 were $0.2 million and $0.4 million, and the net amounts recorded to treasury stock related to the deferred compensation plans during the six months ended June 30, 2017 and 2016 were $3.4 million and $7.8 million. An aggregate of $17.7 million was included in treasury stock for notional amounts related to deferred compensation plans at June 30, 2017. Retirement of Treasury Stock Effective December 1, 2016, Quanta retired 84.8 million shares of treasury stock. These retired shares were restored to the status of authorized and unissued shares as permitted by Delaware law. The retired stock had a carrying value of $1.95 billion. In accordance with Quanta’s policy, Quanta recorded the formal retirement of treasury stock by deducting the par value from common stock and the excess of cost over par value from APIC. Stock repurchases During the second quarter of 2017, Quanta’s board of directors approved a stock repurchase program that authorizes Quanta to purchase, from time to time through June 30, 2020, up to $300.0 million of its outstanding common stock (the 2017 Repurchase Program). Repurchases under the 2017 Repurchase Program can be made in open market and privately negotiated transactions. As of June 30, 2017, Quanta had not repurchased any shares of its common stock under the 2017 Repurchase Program. During the third quarter of 2015, Quanta’s board of directors approved a stock repurchase program that authorized Quanta to purchase, from time to time through February 28, 2017, up to $1.25 billion of its outstanding common stock (the 2015 Repurchase Program). Repurchases under the 2015 Repurchase Program were made in open market and privately negotiated transactions, including pursuant to an accelerated share repurchase arrangement and an issuer repurchase plan. During 2015, Quanta repurchased 19.2 million shares of its common stock at a cost of $449.9 million in the open market under the 2015 Repurchase Program. During the third quarter of 2015, Quanta also entered into an accelerated share repurchase arrangement (the ASR) to repurchase $750.0 million of its common stock under the 2015 Repurchase Program. Under the terms of the ASR, Quanta paid $750.0 million to JPMorgan Chase Bank, National Association, London Branch (JPMorgan) and initially received 25.7 million shares of its common stock. The fair market value of these 25.7 million shares at the time of delivery was $600.0 million, and the repurchased shares and the related cost to acquire them were accounted for as an adjustment to the balance of treasury stock during the third quarter of 2015, reducing the weighted-average number of basic and diluted common shares used to calculate Quanta’s earnings per share. The $150.0 million remaining under the ASR was recorded as an adjustment to APIC during the third quarter of 2015 and was reclassified from APIC to treasury stock upon final settlement of the ASR on April 12, 2016. At final settlement and based on the final volume-weighted average share price during the term of the ASR, minus a discount and subject to other adjustments pursuant to the terms and conditions of the ASR, Quanta received 9.4 million additional shares of its common stock from JPMorgan. The 2015 Repurchase Program ended on February 28, 2017, and Quanta repurchased a total of 54.3 million shares of its common stock at a cost of $1.20 billion under the 2015 Repurchase Program. Other than the shares received at settlement of the ASR in the second quarter of 2016, no common stock was repurchased in the six months ended June 30, 2017 or 2016 under the 2015 Repurchase Program. Other Under Delaware corporate law, treasury stock is not counted for quorum purposes or entitled to vote. Non-controlling Interests Quanta holds investments in several joint ventures that provide infrastructure services under specific customer contracts. Quanta has determined that certain of these joint ventures are VIEs, with Quanta providing the majority of the infrastructure services to the joint venture, which management believes most significantly influences the economic performance of the joint venture. Management has concluded that Quanta is the primary beneficiary of each of the joint ventures determined to be VIEs and has accounted for each on a consolidated basis. The other parties’ equity interests in these joint ventures have been accounted for as “Non-controlling interests” in the accompanying condensed consolidated balance sheets. Net income attributable to the other joint venture members in the amounts of $0.5 million and $0.2 million for the three months ended June 30, 2017 and 2016 and $0.7 million and $0.5 million for the six months ended June 30, 2017 and 2016 has been accounted for as a reduction of net income in deriving “Net income attributable to common stock” in the accompanying condensed consolidated statements of operations. The carrying value of the investments held by Quanta in all of its VIEs was $2.6 million and $3.3 million at June 30, 2017 and December 31, 2016. The carrying value of investments held by the non-controlling interests in these variable interest entities at June 30, 2017 and December 31, 2016 was $2.6 million and $3.3 million. During the three months ended June 30, 2017 and 2016, distributions to non-controlling interests were $0.4 million and none. During the six months ended June 30, 2017 and 2016, distributions to non-controlling interests were $1.4 million and none. There were no other changes in equity as a result of transfers to/from the non-controlling interests during the six months ended June 30, 2017 or 2016. See Note 10 for further disclosures related to Quanta’s joint venture arrangements.
