Our marketable securities utilize Level 1 and Level 2 inputs and consist primarily of corporate securities, which primarily include commercial paper and debt instruments including notes issued by foreign or domestic industrial and financial corporations and governments 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’s contingent consideration obligation was initially recorded at fair value and the Company will revalue this obligation each reporting period until the related contingencies are resolved. The fair value measurement is estimated using probability-weighted discounted cash flow approaches that are based on significant unobservable inputs related to achievement of estimated annual sales and are reviewed quarterly. Significant changes to estimated annual sales and discount rates would result in corresponding changes in the fair value of this obligation. There were no significant changes to the fair value of our contingent consideration liabilities during the six months ended June 30, 2019. The following table presents a reconciliation of the beginning and ending amounts related to the fair value of contingent consideration categorized as Level 3:
