4. ACQUISITIONS AND REVALUATIONS OF NON-CONTROLLING INTERESTS

In four separate transactions during the six months ended June 30, 2014, the Company purchased interests in two partnerships which were previously classified as redeemable non-controlling interest. The interests in the partnerships purchased ranged from 10.0% to 35.0%. The aggregate of the purchase prices paid was $4.9 million, which included $3.0 million of net book value. The remaining purchase price of $1.9 million, less future tax benefits of $0.8 million, was recognized as an adjustment to additional paid-in capital.

For the six months ended June 30, 2014, the following table details the changes in the carrying amount of redeemable non-controlling interest:

	Six Months
	Ended
	June 30, 2014
Beginning balance	$	4,104
Increase due to revaluation and operating results of redeemable non-controlling interests		1,869
Purchases of redeemable non-controlling interests		(4,887	)
Ending balance	$	1,086

The non-controlling interests that are reflected as redeemable non-controlling interests in the consolidated financial statements consist of those owners who have certain redemption rights that are currently exercisable, and that, if exercised, require that the Company purchase the non-controlling interest of those owners. The redeemable non-controlling interests are adjusted to the fair value in the reporting period in which the Company deems it probable that the limited partner will assert the redemption rights and it will be adjusted each reporting period thereafter. The adjustments are charged to additional paid-in capital and are not reflected in the statement of net income. Although the adjustments are not reflected in the statement of net income, current accounting rules require that the Company reflect the charge in the earnings per share calculation.
