		Level 1 –		Quoted prices for identical instruments in active markets.
		Level 2 –		Quoted prices for similar instruments in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations whose inputs are observable or whose significant value drivers are observable.
		Level 3 –		Instruments whose significant drivers are unobservable.

The availability of observable inputs can vary from product to product and is affected by a wide variety of factors, including, for example, the type of product, whether the product is new and not yet established in the marketplace, and other characteristics particular to the transaction. To the extent that valuation is based on models or inputs that are less observable or unobservable in the market, the determination of fair value requires more judgment. Accordingly, the degree of judgment exercised by management in determining fair value is greatest for instruments categorized in Level 3. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, for disclosure purposes, the level in the fair value hierarchy within which the fair value measurement in its entirety falls is determined based on the lowest level input that is significant to the fair value measurement in its entirety.

The tables below summarize the categorization of the Company’s assets and liabilities measured at fair value. During the three and nine months ended September 30, 2019 and 2018 there were no transfers between Levels 1, 2 and 3.

Recurring Fair Value Measurements—Methodology

Cash Equivalents (Note 4)

– These financial assets represent cash invested in highly liquid investments with original maturities of less than 90 days. These investments are valued at par, which approximates fair value, and are considered Level 1.

Securities Owned/Sold but Not Yet Purchased (Note 6)

– Securities owned and sold, but not yet purchased are investments in ETFs. ETFs are generally traded in active, quoted and highly liquid markets and are therefore classified as Level 1 in the fair value hierarchy.

Deferred Consideration

– Deferred consideration represents the present value of an obligation to pay gold into perpetuity and was measured at September 30, 2019 using forward-looking gold prices ranging from $1,467 per ounce to $2,277 per ounce ($1,294 per ounce to $2,621 per ounce at December 31, 2018) which are extrapolated from the last observable price (beyond 2025), discounted at a rate of 10% and includes a perpetual growth rate of 1.5%. This obligation is classified as Level 3 as the discount rate, perpetual growth rate and extrapolated forward-looking gold prices are significant unobservable inputs. An increase in forward-looking gold prices would result in an increase in deferred consideration, whereas an increase in the discount rate would reduce the fair value. See Note 11 for additional information.

The following table presents a reconciliation of beginning and ending balances of recurring fair value measurements classified as Level 3:


	Three Months Ended September 30,						Nine Months Ended September 30,
	2019			2018			2019			2018
Deferred consideration (Note 11)
Beginning balance	$	161,273		$	162,848		$	161,540		$	172,746
Net realized losses (1)		3,502			2,880			9,710			5,595
Net unrealized losses/(gains) (2)		6,306			(7,732	)		5,939			(17,630	)
Settlements		(3,441	)		(1,941	)		(9,549	)		(4,656	)

Ending balance	$	167,640		$	156,055		$	167,640		$	156,055
