FAIR VALUE MEASUREMENTS
FAIR VALUE MEASUREMENTS
We determine estimated fair values for our financial instruments using available information. The fair value amounts discussed in our Condensed Consolidated Financial Statements are not necessarily indicative of either amounts realizable upon disposition of these instruments or our intent or ability to dispose of these assets. The estimated fair value of cash and cash equivalents, accounts receivable, prepaid income taxes, other current assets, accounts payable and accrued liabilities, dividends payable, compensation and benefits payable and income taxes payable approximates their carrying value due to their short-term maturities. The carrying amount of investments designated as “trading” securities, primarily U.S. Government and Government agency obligations, money market funds, Westwood Funds® mutual funds, the UCITS Fund and Westwood Trust common trust fund shares, equals their fair value based on prices quoted in active markets and, with respect to common trust funds, the net asset value of the shares held as reported by each fund. Market values of our money market holdings generally do not fluctuate. Our strategic investment in a private company discussed in Note 4 “Investments” is excluded from the recurring fair value table shown below, as we have elected to apply the measurement alternative for this investment.
ASC 820, Fair Value Measurements, defines fair value, establishes a framework for measuring fair value and requires disclosures regarding certain fair value measurements. ASC 820 establishes a three-tier hierarchy for measuring fair value, as follows:
level 1 – quoted market prices in active markets for identical assets
level 2 – inputs other than quoted prices that are directly or indirectly observable
level 3 – significant unobservable inputs where there is little or no market activity
The following table summarizes the values of our investments measured at fair value on a recurring basis within the fair value hierarchy as of the dates indicated (in thousands):
