Noncontrolling Interests
12. Noncontrolling Interests

We own some of our animal hospitals in partnerships with noncontrolling interest holders. We consolidate our partnerships in our consolidated financial statements because our ownership interest in these partnerships is equal to or greater than 50.1% and we control these entities. We record noncontrolling interest in income of subsidiaries equal to our partners’ percentage ownership of the partnerships’ income. We also record changes in the redemption value of our redeemable noncontrolling interests in net income attributable to noncontrolling interests in our consolidated income statements. Noncontrolling interest in income of subsidiaries was $4.5 million, $3.9 million and $4.2 million in 2011, 2010 and 2009, respectively. In addition, we reflect our noncontrolling partners’ cumulative share in the equity of the respective partnerships as noncontrolling interests in our consolidated balance sheets. At December 31, 2011 and 2010, noncontrolling interest was $10.1 million and $10.6 million, respectively.

a.    Mandatorily Redeemable Noncontrolling Interests

The terms of some of our partnership agreements require us to purchase the partner’s equity in the partnership in the event of the partner’s death. We report these redeemable noncontrolling interests at their estimated redemption value and classify them as liabilities due to the certainty of the related event. We recognize changes in the obligation as an interest cost in the consolidated income statements. At December 31, 2011 and 2010, these liabilities were $3.1 million and $1.7 million, respectively, and are included in other liabilities in our consolidated balance sheets.

b.    Redeemable Noncontrolling Interests

We also enter into partnership agreements whereby the minority partner is issued certain “put” rights. These rights are normally exercisable at the sole discretion of the minority partner. We report these redeemable noncontrolling interests at their estimated redemption value and classify them in temporary equity (mezzanine). We recognize changes in the obligation in net income attributable to noncontrolling interests.
