Deferred Consideration	11. Deferred Consideration ETFS Capital first acquired Gold Bullion Securities Ltd. (“GBS Issuer”), one of the issuers that the Company acquired as part of the ETFS Acquisition, paying no upfront consideration.

11. Deferred Consideration

ETFS Capital first acquired Gold Bullion Securities Ltd. (“GBS Issuer”), one of the issuers that the Company acquired as part of the ETFS Acquisition, paying no upfront consideration. Instead, the consideration was deferred and contracted to be paid by ETFS Capital in fixed payments of physical gold bullion equating to 9,500 ounces of gold per year through March 31, 2058 and then subsequently reduced to 6,333 ounces of gold continuing into perpetuity (the “Contractual Gold Payments”).

ETFS Capital’s deferred consideration obligation did not terminate upon the Company’s acquisition of ETFS. Instead, a wholly-owned subsidiary of the Company assumed the obligation by entering into a Gold Royalty Agreement with ETFS Capital, which provides for the same Contractual Gold Payments payable to ETFS Capital in order for ETFS Capital to continue to satisfy its deferred consideration obligation. The Contractual Gold Payments are paid from advisory fee income generated by the physically backed gold exchange-traded products issued by GBS Issuer and any other Company sponsored financial product backed by physical gold (the “Gold ETCs”). The Contractual Gold Payments are subject to adjustment and reduction for declines in advisory fee income generated by the Gold ETCs, with any reduction remaining due and payable until paid in full. ETFS Capital’s recourse is limited to such advisory fee income and it has no recourse back to the Company for any unpaid amounts that exceed advisory fees earned. ETFS Capital ultimately has the right to claw back GBS Issuer if the Company fails to remit any amounts due.

The Company determined the present value of the deferred consideration of $172,746 and $156,055 at April 11, 2018 (date of acquisition) and September 30, 2018, respectively, using forward-looking gold prices which were extrapolated from the last observable price (beyond 2024), discounted at a rate of 10.0%. Current and long-term amounts payable at September 30, 2018 were $11,788 and $144,267, respectively.

During the three and nine months ended September 30, 2018, the Company recognized Contractual Gold Payments expense of $2,880 and $5,595, respectively, arising from the fixed payments of physical gold bullion of 2,375 ounces and 4,460 ounces, respectively, (or 9,500 ounces per annum) and the unwinding of the discount (representing the increase in the carrying amount of the deferred consideration for the passage of time). A gain on the revaluation of deferred consideration of $7,732 and $17,630 was recognized during the three and nine months ended September 30, 2018, respectively, due to changes in gold prices.
