Fair Value Measurements |
Financial assets and liabilities are recorded at fair value. The carrying amounts of certain of the Company’s financial instruments, including cash and cash equivalents, restricted cash, investments in marketable securities, accounts receivable, accounts payable and other current liabilities approximate their fair value due to their short maturities. Fair value is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The accounting guidance describes a fair value hierarchy based on three levels of inputs that may be used to measure fair value, of which the first two are considered observable and the last is considered unobservable. These levels of inputs are the following: Level 1 — Quoted prices in active markets for identical assets or liabilities. Level 2 — Inputs other than Level 1 that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. Level 3 — Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. The Company’s financial instruments consist of Level 1 and Level 2 assets, and Level 3 liabilities. Where quoted prices are available in an active market, securities are classified as Level 1. Level 1 assets consist of highly liquid money market funds. When quoted market prices are not available for the specific security, then the Company estimates the fair value by using quoted prices for identical or similar instruments in markets that are not active and model-based valuation techniques for which all significant inputs are observable in the market or can be corroborated by observable market data for substantially the full term of the assets. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs obtained from various third party data providers, including but not limited to, benchmark yields, interest rate curves, reported trades, broker/dealer quotes and market reference data. Level 2 assets consist of corporate notes and commercial paper. Level 2 inputs for the valuations are limited to quoted prices for similar assets or liabilities in active markets and inputs other than quoted prices that are observable for the asset or liability. In certain cases where there is limited activity or less transparency around inputs to valuation, securities are classified as Level 3. Level 3 liabilities consist of the contingent consideration. There were no transfers between Level 1, Level 2 and Level 3 during the periods presented. Financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used in such measurements are as follows (in thousands):
Cash equivalents, investments in marketable securities, which are classified as available-for-sale securities, and restricted cash, consisted of the following (in thousands):
As of March 31, 2019, the remaining contractual maturities of available-for-sale securities were less than one year. The average maturity of investments in marketable securities available-for-sale as of March 31, 2019 was approximately three months. The gross realized gains were $112,000 and $82,000 for the three months ended March 31, 2019 and 2018, respectively, and the gross realized losses were $0 for both the three months ended March 31, 2019 and 2018, in the condensed consolidated statement of operations. Contingent Consideration As part of the InteKrin acquisition in February 2014, the Company recognized contingent consideration associated with potential payments to be made to the former InteKrin stockholders upon (i) the first dosing of a human subject in the first Phase 2 Clinical Trial for CHS-131 ("Earn-Out Payment") and (ii) per a compound transaction agreement as defined in the purchase agreement (the “Compound Transaction Payment”). The contingent consideration related to the Earn-Out Payment was settled on March 6, 2015. The fair value measurement of the Compound Transaction Payment uses a probability-weighted discounted cash flow approach based on significant inputs not observable in the market and thus represents a Level 3 measurement within the fair value hierarchy. The compound transaction analysis as of March 31, 2019 applied a 25% risk-adjusted discount rate to measure the present value and also captured an additional 8% credit spread for counterparty credit risk given the cash payment. The expected cash flow is based on estimates provided by the Company’s management including the timing and probability of occurrence. The value of the consideration is tiered based on the value of a license or similar agreement with a third party and the timing of such agreement. Generally, increases or decreases in the probability of occurrence would result in a directionally similar impact in the fair value measurement of the Compound Transaction Payment and it is estimated that a 1% increase (decrease) in the probability of occurrence would result in an immaterial fair value fluctuation. The change in the fair value of the Compound Transaction Payment was recognized in other income (expense), net within the condensed consolidated statement of operations of $4,000 and $208,000 for the three months ended March 31, 2019 and 2018, respectively. The following table sets forth a summary of changes in the estimated fair value of the contingent consideration (in thousands):
Convertible Notes The estimated fair value of the 8.2% Convertible Senior Notes Due 2022, which the Company issued on February 29, 2016 (see Note 7) is based on an income approach. The estimated fair value was approximately $106.9 million (par value $100.0 million) as of March 31, 2019 and represents a Level 3 valuation. When determining the estimated fair value of the Company’s long-term debt, the Company uses a single factor binomial lattice model, which incorporates the terms and conditions of the convertible notes and market based risk measurement that are indirectly observable, such as credit risk. The lattice model produces an estimated fair value based on changes in the price of the underlying common shares price over successive periods of time. An estimated yield based on market data is used to discount straight debt cash flows. |
