Note 8.    Stockholders’ Equity

Share-based Compensation Plans

We periodically grant restricted stock unit awards and/or shares of common stock to our employees and directors. Grants to individual executives upon hiring or retention vest over a defined service period, with cost amortized over that period. We measure compensation cost for restricted stock units and stock grants at the closing price of our stock at the time of grant. Restricted stock unit grants vest after a specified period with compensation cost amortized over that period. Although we have no current plans to issue stock options, we have in the past and may do so in the future.

On March 5, 2015, the Board of Directors granted 911,148 shares of common stock to employees for payment of annual and long-term incentive compensation for the period ended December 31, 2014. The shares were distributed in March 2015, and the $3.0 million in expense related to the stock awards has been recognized as of March 31, 2015.

Stock-based compensation expense recorded in the first three months of both 2015 and 2014 totaled $1.1 million and was related to amortization of restricted stock unit grants to employees in prior periods.

In connection with the vesting of restricted stock units or other issuances of common stock to employees as compensation, employees have in the past, at their election and when permitted by us, chosen to satisfy their tax withholding obligations through net share settlement, pursuant to which the Company withholds the number of shares necessary to satisfy such withholding obligations.  Pursuant to such net settlements, in the first quarter of 2015 we repurchased 284,243 shares for approximately $941,000, or approximately $3.31 per share.

Common Stock Dividends

In September 2011 and February 2012, our Board of Directors adopted a common stock dividend policy that has two components: (1) a dividend that links the amount of dividends on our common stock to our average quarterly realized silver price in the preceding quarter, and (2) a minimum annual dividend of $0.01 per share of common stock, in each case, payable quarterly, when and if declared by the Board. For illustrative purposes only, the table below summarizes potential per share dividend amounts at different quarterly average realized price levels according to the first component of the policy:

Quarterly average realized silver price per ounce	Quarterly dividend per share	Annualized dividend per share
$30	$0.01	$0.04
$35	$0.02	$0.08
$40	$0.03	$0.12
$45	$0.04	$0.16
$50	$0.05	$0.20
$55	$0.06	$0.24
$60	$0.07	$0.28

On May 6, 2015, our Board of Directors declared a dividend on common stock, pursuant to the minimum annual dividend component of the policy described above, of $0.0025 per share, for a total dividend of $0.9 million payable in June 2015. Because the average realized silver price for the first quarter of 2015 was $17.18 per ounce, below the minimum threshold of $30 according to the policy, no silver-price-linked component was declared or paid. The declaration and payment of common stock dividends is at the sole discretion of our Board of Directors.

Common Stock Repurchase Program

On May 8, 2012, we announced that our Board of Directors approved a stock repurchase program.  Under the program, we are authorized to repurchase up to 20 million shares of our outstanding common stock from time to time in open market or privately negotiated transactions, depending on prevailing market conditions and other factors.  The repurchase program may be modified, suspended or discontinued by us at any time. Whether or not to engage in repurchases from time to time may depend on a variety of factors, including not only price and cash resources, but customary black-out restrictions, whether we have any material inside information, limitations on share repurchases or cash usage that may be imposed by our credit agreement or in connection with issuances of securities, alternative uses for cash, applicable law, and other investment opportunities from time to time. As of March 31, 2015, 934,100 shares have been purchased in prior periods at an average price of $3.99 per share, leaving 19.1 million shares that may yet be purchased under the program. The closing price of our common stock at May 5, 2015, was $3.01 per share.
