Fair Value Measurements

Factors used in determining the fair value of our financial assets and liabilities are summarized into three broad categories:

•
Level 1 – quoted prices in active markets for identical securities as of the reporting date;
•
Level 2 – other significant directly or indirectly observable inputs, including quoted prices for similar securities, interest rates, prepayment speeds and credit risk; and
•
Level 3 – significant inputs that are generally less observable than objective sources, including our own assumptions in determining fair value.

The factors or methodology used for valuing securities are not necessarily an indication of the risk associated with investing in those securities.

The following table summarizes liabilities measured at fair value on a recurring basis (in thousands):

We did not have any assets measured at fair value on a recurring basis at September 30, 2016 or December 31, 2015.

The fair value of our interest rate swaps were based on quarterly statements from the issuing bank. There were no changes to our valuation techniques during the nine months ended September 30, 2016.

We believe the carrying amounts of Cash and cash equivalents, Accounts receivable, Other current assets, Accounts payable, Accrued salaries, wages and payroll taxes, and Other accrued expenses are a reasonable approximation of the fair value of those financial instruments because of the nature of the underlying transactions and the short-term maturities involved.

We had fixed-rate debt outstanding as follows (in thousands):

We calculate the estimated fair value of our fixed-rate debt using a discounted cash flow methodology. Using estimated current interest rates based on a similar risk profile and duration (Level 2), the fixed cash flows are discounted and summed to compute the fair value of the debt.
