The assets and liabilities for all acquisitions were recorded at their estimated fair values at the dates of the acquisitions and are included in the Company’s financial statements and operating results from the effective dates of the acquisitions. For several of the 2015 acquisitions, certain income tax amounts are pending final evaluation and quantification of any pre-acquisition tax contingencies. In addition, valuation of medical claims liabilities and certain other working capital items relating to several of these acquisitions are pending final quantification.

The following table summarizes the assets acquired and liabilities assumed in the above described transactions and recognized at their acquisition dates at estimated fair values, as well as the estimated fair value of the noncontrolling interests assumed in these transactions:

The weighted-average amortization period for customer relationships was 10 and 17 years for 2014 and 2013, respectively. The weighted-average amortization period for non-compete agreements was 8 years for both 2015 and 2014, and 9 years for 2013. The total amount of goodwill deductible for tax purposes associated with these acquisitions for 2015, 2014, and 2013 was approximately $73,733, $175,247 and $221,454, respectively.

Contingent earn-out obligations

The Company has several contingent earn-out obligations associated with acquisitions that could result in the Company paying the former shareholders of acquired companies a total of up to approximately $129,626 if certain EBITDA, operating income performance targets or quality margins are met over the next one to two years.

Contingent earn-out obligations are remeasured to fair value at each reporting date until the contingencies are resolved with changes in the liability due to the remeasurement recorded in earnings. See Note 24 to the consolidated financial statements for further details. As of December 31, 2015, the Company has estimated the fair value of these contingent earn-out obligations to be $34,135, of which a total of $29,050 is included in other liabilities and the remaining $5,085 is included in other long-term liabilities in the Company’s consolidated balance sheet.

The following is a reconciliation of changes in the contingent earn-out obligations for the year ended December 31, 2015:

Beginning balance, January 1, 2015	$	39,129
Contingent earn-out obligations associated with acquisitions		990
