For the three and nine months ended September 28, 2014, the Company recorded net reductions to contingent consideration liabilities of $1.5 million and $8.2 million, respectively, and for the three and nine months ended September 29, 2013, the Company recorded reductions to contingent consideration liabilities of $4.4 million and $12.4 million, respectively. These reductions were the result of changes in probabilities associated with certain regulatory and sales milestones. Valuation Techniques The Company’s financial assets valued based upon Level 1 inputs are comprised of investments in marketable securities held in trust, which are available to pay benefits under certain deferred compensation plans and other compensatory arrangements. The investment assets of the trust are valued using quoted market prices. The Company’s financial assets and financial liabilities valued based upon Level 2 inputs are comprised of foreign currency forward contracts. The Company uses foreign currency forward contracts to manage currency transaction exposure. The fair value of the foreign currency forward contracts represents the amount required to enter into offsetting contracts with similar remaining maturities based on quoted market prices. The Company has taken into account the creditworthiness of the counterparties in measuring fair value. The Company’s financial liabilities valued based upon Level 3 inputs are comprised of contingent consideration arrangements pertaining to the Company’s acquisitions. The Company accounts for contingent consideration in accordance with applicable accounting guidance related to business combinations. In connection with several of its acquisitions, the Company agreed to pay contingent consideration upon the achievement of specified objectives, including receipt of regulatory approvals, achievement of sales targets and, in some instances, the passage of time (collectively, “milestone payments”), and therefore recorded contingent consideration liabilities at the time of the acquisitions. The Company is required to reevaluate the fair value of contingent consideration each reporting period based on new developments and record changes in fair value until such consideration is satisfied through payment upon the achievement of the specified objectives or is no longer payable due to failure to achieve the specified objectives. In connection with the Company's contingent consideration arrangements, the Company estimates that it will make payments in 2015 and may make payments until 2018 or later. As of September 28, 2014, the range of undiscounted amounts the Company could be required to pay under contingent consideration arrangements is between zero and $56.5 million. The Company determines the fair value of the liabilities for the contingent consideration based on a probability-weighted discounted cash flow analysis. This fair value measurement is based on significant inputs not observable in the market and thus represents a Level 3 measurement within the fair value hierarchy. The fair value of the contingent consideration liability associated with future payments under contingent consideration arrangements is based on several factors including:
l | estimated cash flows projected from the success of market launches;
l | the estimated time and resources needed to complete the development of acquired technologies;
l | the uncertainty of obtaining regulatory approvals within the required time periods; and
l | the risk adjusted discount rate for fair value measurement.
The following table provides information regarding the valuation techniques and inputs used in determining the fair value of assets or liabilities categorized as Level 3 measurements as of September 28, 2014:
| Valuation Technique |  | Unobservable Input |  | Range (Weighted Average)
Contingent consideration | Discounted cash flow |  | Discount rate |  | 2.3% - 10% (8.6%)
|  |  | Probability of payment |  | 0% - 100% (28.3%)
As of September 28, 2014, of the $12.6 million of total recorded liabilities for contingent consideration, the Company has recorded approximately $3.0 million of contingent consideration as a current liability, and the remaining $9.6 million within other liabilities.
