Our marketable securities utilize Level 2 inputs and consist primarily of corporate securities which include commercial paper and corporate debt instruments including notes issued by foreign or domestic corporations which pay in U.S. dollars and carry a rating of A or better. We have evaluated the various types of securities in our investment portfolio to determine an appropriate fair value hierarchy level based upon trading activity and the observability of market inputs. Due to variations in trading volumes and the lack of quoted market prices in active markets, our fixed maturities are classified as Level 2 securities. The fair value of our fixed maturity marketable securities is derived through the use of a third party pricing source using recent reported trades for identical or similar securities, making adjustments through the reporting date based upon available market observable data. The Company used the income approach to value the contingent consideration. The contingent consideration used a discounted cash flow method with probability weighted cash flows for Endeka. The following table presents a reconciliation of the beginning and ending amounts related to the fair value of contingent consideration categorized as Level 3:
Beginning balance, January 1, 2014 |  | $ | 1,942 |
Payment of contingent consideration |  |  | (1,000 | )
