Note 15. Fair Value

The carrying amount of rents and other receivables, restricted cash, escrow deposits, prepaid expenses and other assets, and accounts payable and accrued expenses approximate fair value because of the short maturity of these amounts. The Company's interest rate cap agreement, contingently convertible Series E units liability and preferred shares derivative liability are the only financial instruments recorded at fair value on a recurring basis in the consolidated financial statements.

Inputs to the model used to value the contingently convertible Series E units liability include a risk-free rate corresponding to the assumed timing of the conversion date and a volatility input based on the historical volatilities of selected peer group companies. The starting point for the simulation is the most recent trading price in the Company's Class A common shares, into which the Series E units are ultimately convertible. The timing of such conversion is based on the provisions of the contribution agreement and the Company's best estimate of the events that trigger such conversions.

Valuation of the preferred shares derivative liability considers scenarios in which the preferred shares would be redeemed or converted into Class A common shares by the Company and the subsequent payoffs under those scenarios. The valuation also considers certain variables such as the risk-free rate matching the assumed timing of either redemption or conversion, volatility of the underlying home price appreciation index, dividend payments, conversion rates, the assumed timing of either redemption or conversion and an assumed drift factor in home price appreciation across certain MSAs as outlined in the agreement.

The fair value of our interest rate cap agreement is determined using the market standard methodology of discounting the future expected cash receipts that would occur if variable interest rates rise above the strike rate of the interest rate cap. The variable interest rates used in the calculation of projected receipts on the cap are based on an expectation of future interest rates derived from observable market interest rate curves and volatilities. To comply with the provisions of ASC 820, Fair Value Measurements and Disclosures, the Company incorporates credit valuation adjustments to appropriately reflect the respective counterparty's nonperformance risk in the fair value measurements.

The following tables set forth the fair value of our interest rate cap agreement, the contingently convertible Series E units liability and preferred shares derivative liability as of December 31, 2014 and 2013 (in thousands):
