The Company measures the above items on a recurring basis at fair value as follows:
 
Money market funds — Classified in Level 1 is excess cash the Company may hold in both taxable and tax-exempt money market funds, and is included in cash and cash equivalents in the accompanying unaudited condensed consolidated balance sheets. The Company records any net unrealized gains and losses for changes in fair value as a component of accumulated other comprehensive income in stockholders’ equity. Realized gains and losses from the sale of marketable securities are based on the specific identification method. The Company’s remaining cash and cash equivalents held at December 31, 2012 and September 30, 2013, approximate fair value and is not disclosed in the above tables because of the short-term nature of the financial instruments.
 
Interest rate swap — The Company has two interest rate swaps with a notional amount of $122.7 million as of September 30, 2013, used to minimize the interest rate exposure and fix the variable interest rate on a portion of the Company’s variable rate debt. The swaps are classified within Level 2 and are valued using readily available pricing sources which utilize market observable inputs including the current variable interest rate for similar types of instruments.
 
Deferred payments — The Company acquired certain assets and entered into a deferred payment arrangement with one of the sellers, which are classified within Level 3 as there is no liquid market for similarly priced instruments.  The deferred payments are valued using a discounted cash flow model that encompassed significant unobservable inputs to estimate the operating results of the acquired assets. The assumptions used to prepare the discounted cash flows include estimates for interest rates, enrollment growth, retention rates and pricing strategies. These assumptions are subject to change as the underlying data sources evolve and the program matures.
 
At September 30, 2013, the carrying value of the Company’s debt, which is variable interest rate debt, was $122.7 million and approximates fair value. Variable interest rates are established by market data and used with other observable inputs to estimate fair value measurements, which are categorized as Level 2 measurements under ASC 820.
 
 
The Company did not change its valuation techniques associated with recurring fair value measurements from prior periods, and no assets or liabilities were transferred between levels of the fair value hierarchy during the nine months ended September 30, 2012 or 2013. Assets measured at fair value on a non-recurring basis as of December 31, 2012 and September 30, 2013, include $6.8 million of goodwill and $1.6 million of other indefinite-lived intangible assets. The changes in the fair value of the Company’s Level 3 liability during the nine months ended September 30, 2013 are as follows (in thousands):
