Non-controlling Interests / Redeemable Non-controlling Interests	Non-controlling Interests / Redeemable Non-controlling Interests Certain of the Company’s consolidated joint ventures have put options which, if exercised by the Company’s joint venture partner, would require the Company to purchase all or a portion of the joint venture partner’s equity interest in the joint venture. The Company has determined that these put options are not derivatives under the guidelines prescribed in Accounting Standards Codification (“ASC”) 815. As such, and in accordance with ASC 480-10-S99, as the potential exercise of the put options is outside the control of the Company, the Company has recorded the portion of the non-controlling interest’s equity that may be put to the Company in mezzanine equity in the Company’s consolidated balance sheets as “redeemable non-controlling interest”. The initial value of the redeemable non-controlling interest represents the fair value of the put option at inception. This amount recorded at inception is accreted, over a period determined by when the put option becomes exercisable, to what the Company would be obligated to pay to the non-controlling interest holder if the put option was exercised. This accretion is recorded as a credit to redeemable non-controlling interest and a debit to retained earnings resulting in an impact to the consolidated balance sheet only. For each reporting period, the Company revisits the estimates used to determine the redemption value of the put option when it becomes exercisable and may adjust the remaining put option value and associated accretion accordingly through redeemable non-controlling interest and retained earnings, as necessary. The terms of each of the outstanding put options are included in the individual discussions of each joint venture, as applicable. For the Company’s consolidated joint ventures that do not have put options, the non-controlling interest is recorded within equity on the Company’s consolidated balance sheet. The Company may enter into joint venture agreements with joint venture partners in which the Company allows the joint venture partner to pay a portion of the purchase price in cash at the time of the formation of the joint venture with the remaining cash consideration paid over a specified period of time following the closing of such transaction. The Company records the amounts due from such joint venture partners as (a) a reduction of non-controlling Interests, net of installment payments, or (b) if installment payments result from the issuance of shares classified as mezzanine equity, as a reduction in Redeemable Non-controlling Interests, net of installment payments (i.e. mezzanine equity), as applicable, in the Company’s consolidated balance sheet accordance with ASC 505-10-45, “Classification of a Receivable from a Shareholder.” The Company accretes the present value discount on these installment payments through interest income on its consolidated statements of operations.

Non-controlling Interests / Redeemable Non-controlling Interests

Certain of the Company’s consolidated joint ventures have put options which, if exercised by the Company’s joint venture partner, would require the Company to purchase all or a portion of the joint venture partner’s equity interest in the joint venture. The Company has determined that these put options are not derivatives under the guidelines prescribed in Accounting Standards Codification (“ASC”) 815. As such, and in accordance with ASC 480-10-S99, as the potential exercise of the put options is outside the control of the Company, the Company has recorded the portion of the non-controlling interest’s equity that may be put to the Company in mezzanine equity in the Company’s consolidated balance sheets as “redeemable non-controlling interest”. The initial value of the redeemable non-controlling interest represents the fair value of the put option at inception. This amount recorded at inception is accreted, over a period determined by when the put option becomes exercisable, to what the Company would be obligated to pay to the non-controlling interest holder if the put option was exercised. This accretion is recorded as a credit to redeemable non-controlling interest and a debit to retained earnings resulting in an impact to the consolidated balance sheet only. For each reporting period, the Company revisits the estimates used to determine the redemption value of the put option when it becomes exercisable and may adjust the remaining put option value and associated accretion accordingly through redeemable non-controlling interest and retained earnings, as necessary. The terms of each of the outstanding put options are included in the individual discussions of each joint venture, as applicable. For the Company’s consolidated joint ventures that do not have put options, the non-controlling interest is recorded within equity on the Company’s consolidated balance sheet.

The Company may enter into joint venture agreements with joint venture partners in which the Company allows the joint venture partner to pay a portion of the purchase price in cash at the time of the formation of the joint venture with the remaining cash consideration paid over a specified period of time following the closing of such transaction.
