Investments

At September 30, 2012 and December 31, 2011, the fair value of our non-current investments was $9.0 million and $3.9 million, respectively. Our non-current investments consist of marketable equity securities, which are carried at fair value as they are classified as “available-for-sale.” The cost basis of our non-current investments was approximately $6.8 million and $3.5 million at September 30, 2012 and December 31, 2011, respectively. The increase in the basis of non-current investments is related to an acquisition of $3.3 million of equity securities in August 2012.

At September 30, 2012, total unrealized gain positions of $2.9 million, net of unrealized losses of $0.6 million, for our non-current investments were included in accumulated other comprehensive loss.

Restricted Cash and Investments

Various laws, permits, and covenants require that financial assurances be in place for certain environmental and reclamation obligations and other potential liabilities. These restricted investments are used primarily for reclamation funding or for funding surety bonds, and were $0.9 million at September 30, 2012 and December 31, 2011. Restricted investments primarily represent investments in money market funds and certificates of deposit.

- Definition

The entire footnote disclosure for cash and cash equivalents and investments, including restricted amounts. Cash and equivalents include: (1) currency on hand (2) demand deposits with banks or financial institutions (3) other kinds of accounts that have the general characteristics of demand deposits (4) short-term, highly liquid investments that are both readily convertible to known amounts of cash and so near their maturity that they present insignificant risk of changes in value because of changes in interest rates. Generally, only investments maturing within three months from the date of acquisition qualify. Investments include investments in Certain Debt and Equity Securities (and certain other trading assets) which include all debt and equity securities (other than those equity securities accounted for under the equity or cost methods of accounting) with readily determinable fair values. Other trading assets include assets that are carried on the balance sheet at fair value and held for trading purposes. A debt security represents a creditor relationship with an enterprise that is in the form of a security. Debt securities include, among other items, US Treasury securities, US government securities, municipal securities, corporate bonds, convertible debt, commercial paper, and all securitized debt instruments. An equity security represents an ownership interest in an enterprise or the right to acquire or dispose of an ownership interest in an enterprise at fixed or determinable prices. Equity securities include, among other things, common stock, certain preferred stock, warrant rights, call options, and put options, but do not include convertible debt. An entity may opt to provide the reader with additional narrative text to better understand the nature of investments in debt and equity securities (and other trading assets).
