Fair Value of Financial Instruments | 7. Fair value of financial instruments: For certain of Solitario's financial instruments, including cash and cash equivalents, payables and short-term debt, the carrying amounts approximate fair value due to their short maturities. Solitario's marketable equity securities, including its investment in Kinross common stock, TNR Gold and the First and Second Ely Equity Investments are carried at their estimated fair value primarily based on publicly available quoted market prices. The Kinross Collar and the Ely Warrants are carried at their estimated fair value based on a Black-Scholes option pricing model. Effective January 1, 2008, Solitario adopted ASC 820, "Fair Value Measurements." ASC 820 establishes a framework for measuring fair value and requires enhanced disclosures about fair value measurements. ASC 820 clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants. ASC 820 also requires disclosure about how fair value is determined for assets and liabilities and establishes a hierarchy for which these assets and liabilities must be grouped, based on significant levels of inputs as follows: Level 1: Quoted prices in active markets for identical assets or liabilities; Level 2: Quoted prices in active markets for similar assets and liabilities and inputs that are observable for the asset or liability; or Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to develop its own assumptions. The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that is significant to the fair value measurement. During 2011 Solitario reclassified the shares underlying the Second Ely Equity Investment from Level 2 to Level 1 upon the expiration of statutory holding requirements. During the year ended December 31, 2011 and 2010, there were no other reclassifications in financial assets or liabilities between Level 1, 2 or 3 categories. The following is a listing of Solitario’s financial assets and liabilities required to be measured at fair value on a recurring basis and where they are classified within the hierarchy as of December 31, 2011:
(in thousands) | Level 1 | Level 2 | Level 3 | Total
Assets |  |  |  |
Marketable equity securities | $10,361 | $ - | $ - | $10,361
Other current assets - Ely warrants | - | 74 | - | 74
Other current assets - ILC warrants | - | 4 | - | 4
The following is a listing of Solitario’s financial assets and liabilities required to be measured at fair value on a recurring basis and where they are classified within the hierarchy as of December 31, 2010:
(in thousands) | Level 1 | Level 2 | Level 3 | Total
Assets |  |  |  |
Marketable equity securities | $18,771 | $ - | $ - | $18,771
Marketable equity securities – Ely common stock | 500 | 500 |  | 1,000
Kinross Collar derivative instrument | - | 2 | - | 2
Other assets - Ely warrants |  | 366 |  | 366
Items measured at fair value on a recurring basis: Marketable equity securities: At December 31, 2011 and 2010, the fair value of Solitario’s investment in Kinross, TNR and Ely marketable equity securities is based upon quoted market prices. At December 31, 2010, the Ely shares issued on October 19, 2010 are classified as Level 2, because they were still subject to a hold period, which expired in January 2011. Ely and ILC warrants: The Ely warrants are not traded on any public exchange. Solitario determines the fair value of the Ely warrants using a Black-Scholes pricing model, using inputs, including share price, volatility of Ely common stock and discount rates that include an assessment of performance risk, that are readily available from public markets and for the hold period discussed above, therefore they are classified as Level 2 inputs as of December 31, 2011 and 2010. The ILC warrants are not traded on a public exchange. Solitario estimates the value of the ILC warrants using a Black-Scholes model and inputs that were readily available from public markets, and has classified these as a Level 2 input as of December 31, 2011. Kinross Collar: The Kinross Collar between Solitario and UBS was a contractual hedge that was not traded on any public exchange. Solitario determined the fair value of the Kinross Collar using a Black-Scholes model using inputs, including the price of a share of Kinross common stock and the volatility of the Kinross common stock price that are readily available from public markets, and discount rates that include an assessment of performance risk; therefore, they were classified as Level 2 inputs. See Note 6 “Derivative instruments” above. Items measured at fair value on a nonrecurring basis: Mt. Hamilton long-term debt: In 2010 the long-term debt associated with the Mt. Hamilton claims was discounted using Solitario’s estimate of a market interest rate to obtain similar financing. Solitario did not have access to a readily traded market for similar credit risks and estimated the interest rate based upon what similar interest rates were on publicly held debt instruments issued by mining companies traded on public markets, what Solitario was borrowing money on its short-term margin accounts, and a discussion with an investment banking firm regarding what Solitario may be able to borrow to fund the Mt. Hamilton project. Solitario discounted the $3,750,000 required payments at an interest rate of 7.5%. Accordingly these inputs are classified as Level 3 inputs. Mt. Hamilton property valuation: In 2010 Solitario determined the fair value of the mineral claims making up the Mt. Hamilton project upon its investment in MH-LLC based upon: (i) Solitario’s evaluation of similar non-producing mining properties, without proven and probable reserves based upon Solitario’s experience in these types of transactions; (ii) an analysis of the fair values of the liabilities assumed and the equity interests received upon the formation of MH-LLC; (iii) a review of the funds previously expended and capitalized by Ely in their historical financial statements; and (iv) a review of the stated estimated value of the Mt. Hamilton property transferred to MH-LLC in the transaction documents between DHI-US and Solitario upon the formation of MH-LLC. Accordingly, these inputs are classified as Level 3 inputs. Deconsolidation of PBM: In 2010 upon Anglo earning a 51% interest in PBM, discussed below in Note 11, “Deconsolidation of PBM,” Solitario deconsolidated PBM in accordance with ASC 810-10-40 whereby Solitario performed a valuation using Level 3 inputs of its 49% interest in the assets of PBM on the date of deconsolidation. The fair value analysis examined four valuation techniques and used assumptions of management on future results and included: (i) the present value of future cash flows; (ii) a market valuation analysis of publicly traded entities with exploration exposure to platinum group metals, similar to PBM; (iii) an analysis of the market value based upon sales and joint ventures of similar exploration properties and projects; and (iv) the recent investment by Anglo to earn an additional 21% interest in PBM. During the year ended December 31, 2011, Solitario did not change any of the valuation techniques used to measure its financial assets and liabilities at fair value.
