(11) Fair Value Measurements

The fair value hierarchy established by ASC 820, Fair Value Measurement, prioritizes the use of inputs used in valuation techniques into the following three levels:

Level 1 inputs are observable quoted prices in active markets for identical assets or liabilities

Level 2 inputs are observable, either directly or indirectly, but are not Level 1 inputs

Level 3 inputs are unobservable

The following table presents, by fair value hierarchy level, the Company’s assets that are measured at fair value on a recurring basis, as of June 30, 2017 and December 31, 2016:



	As of June 30, 2017								As of December 31, 2016

(a)Includes money market funds with original maturity dates of three months or less.

(b)Investments in lieu of customer retainage are included in accounts receivable and are comprised of money market funds and municipal bonds, the majority of which are rated A3 or better. The fair values of the money market funds are measured using quoted market prices; therefore, they are classified as Level 1 assets. The fair values of municipal bonds are measured using readily available pricing sources for comparable instruments; therefore, they are classified as Level 2 assets.

(c)Restricted investments are held as collateral to secure our insurance related contingent obligations. The balances of these investments are held to maturity and are carried at their amortized cost of $9.3 million, which are included in other current assets. These restricted investments are comprised of various corporate bonds and bank notes which are rated A2 or better. The fair values of the corporate bonds and bank notes are measured using readily available sources for comparable instruments; therefore, they are classified as Level 2 assets.

The Company did not have material transfers between Levels 1 and 2 during the six months ended June 30, 2017 or 2016.

The carrying values of receivables, payables and other amounts arising out of normal contract activities, including retainage, which may be settled beyond one year, are estimated to approximate fair value. Of the Company’s long-term debt, the fair value of the 2017 Senior Notes as of June 30, 2017 was $526.3 million. The fair value of the 2010 Senior Notes as of December 31, 2016 was $302.6 million; the 2010 Senior Notes were redeemed in the second quarter of 2017, as discussed in Note 6. The fair value of the Convertible Notes was $238.4 million and $228.4 million as of June 30, 2017 and December 31, 2016, respectively. The fair values of the 2017 Senior Notes, 2010 Senior Notes and Convertible Notes were determined using Level 1 inputs, specifically current observable market prices. The reported value of the Company’s remaining long-term debt at June 30, 2017 and December 31, 2016 approximates fair value.
