At December 31, 2013, we had 100 million shares of common stock authorized and 48.4 million shares issued and outstanding.

On March 6, 2012, we issued 361,446 shares of our common stock and contributed the shares to our primary U.S. pension plan. Sales of these shares by the plan are covered under our shelf registration statement. The common stock was valued for purposes of the contribution at $24.90 per share, or $9 million in the aggregate, which reflected a 2.4% discount from the $25.51 per share closing share price of our common stock on March 5, 2012.

We paid regular quarterly dividends on our common stock during the last three years. On January 16, 2014, the board declared a regular quarterly dividend of 10 cents per share payable on March 3, 2014. The payment of future dividends is at the discretion of the board of directors and is dependent on our future earnings, financial condition, shareholder equity levels, cash flow, business requirements and other factors.

On February 28, 2012, we filed a shelf registration statement under Form S-3ASR with the SEC for $150 million of our common stock. At December 31, 2013, $141.5 million remains available under this shelf registration.

At December 31, 2013, we had the authority to issue up to 2.0 million shares of preferred stock with a par value of $10 per share.

(a) We have deferred compensation plans for directors and certain of our employees. Amounts owed to participants are denominated in common stock units. Each unit represents one share of common stock. The number of shares used to calculate basic earnings per share includes the weighted-average units credited to employees and directors under the deferred compensation plans. Additionally, non-participating restricted stock units are also included in the computation of basic weighted average shares when the requisite service period has been completed. Accordingly, basic and diluted shares include weighted-average units of 0.6 million in 2013, 0.9 million in 2012 and 1.1 million in 2011.
