The Company’s long‑term investment financial instruments are presented in the table of financial assets and liabilities measured at fair value within this note. Concentrations of Credit Risk of Financial Instruments The Company is potentially subject to concentrations of credit risk related to its cash, cash equivalents, and short‑term investments. The Company reduces credit risk by maintaining its cash deposits primarily in FDIC‑insured accounts and placing its unrestricted short‑term investments primarily in FDIC‑insured certificates of deposit with varying original maturities of ninety‑one days to one year. However, certain cash deposits and certificates of deposit may exceed federally insured limits. At December 31, 2013 and 2012, cash, cash equivalents, and certificates of deposit totaling $49.4 million and $53.8 million, respectively, were not FDIC insured. Fair Value Disclosure of Financial Instruments The fair value of the Company’s Term Loan and notes payable debt obligations (see Note H) approximate the amounts recorded in the consolidated balance sheets as presented in the following table:
| December 31 2013 |  | December 31 2012
| (in thousands)
| Carrying Value |  | Fair Value |  | Carrying Value |  | Fair Value
Term Loan(1) | $ | 83,750 |  |  | $ | 83,750 |  |  | $ | 95,000 |  |  | $ | 95,000 |

| $ | 105,832 |  |  | $ | 105,842 |  |  | $ | 132,756 |  |  | $ | 132,904 |
(1) | The Term Loan, which was entered into on June 15, 2012, carries a variable interest rate based on LIBOR, plus a margin, that is considered to be priced at market for debt instruments having similar terms and collateral requirements (Level 2 of the fair value hierarchy).
(2) | Fair value of the notes payable was determined using a present value income approach based on quoted interest rates from lending institutions with which the Company would enter into similar transactions (Level 2 of the fair value hierarchy).
Financial Assets Measured at Fair Value The following table presents the assets that are measured at fair value on a recurring basis, based upon quoted prices for identical assets in active markets (Level 1 of the fair value hierarchy) as of December 31:
| 2013 |  | 2012
| (in thousands)
Money market funds(1) | $ | 12,101 |  |  | $ | 12,602 |

(1) | Included in cash equivalents at December 31, 2013 and in cash equivalents and restricted cash equivalents at December 31, 2012.
(2) | Nonqualified deferred compensation plan investments consist of U.S. and international equity mutual funds, government and corporate bond mutual funds, and money market funds which are held in a trust with a third‑party brokerage firm. Quoted market prices are used to determine fair values of the investments which are included in other long‑term assets, with a corresponding liability reported within other long‑term liabilities.
