Stockholders' Equity

13. Stockholders’ Equity

2008 Stock Incentive Plan - During 2014, our stockholders approved an amendment to our Incentive Stock Plan (the “2008 Plan”). As amended, the total number of shares of our common stock for which awards may be granted under the 2008 Plan is 1,975,000 shares, subject to adjustment. Under the 2008 Plan, awards may be made to any employee, officer or director of the Company and its affiliated companies. An award may also be granted to any consultant, agent, advisor or independent contractor for bona fide services rendered to the Company or any affiliate (as defined in the 2008 Plan), subject to certain conditions. The 2008 Plan is being administered by the compensation and stock option committee (the “Committee”) of our Board of Directors.

Our Board of Directors or the Committee may amend the 2008 Plan, except that if any applicable statute, rule or regulation requires shareholder approval with respect to any amendment of the 2008 Plan, then to the extent so required, shareholder approval will be obtained. Shareholder approval will also be obtained for any amendment that would increase the number of shares stated as available for issuance under the 2008 Plan. Unless sooner terminated by our Board of Directors, the 2008 Plan expires on June 5, 2018.

The following may be granted by the Committee under the 2008 Plan:

Stock Options - The Committee may grant either incentive stock options or non-qualified stock options. The Committee sets option exercise prices and terms, except that the exercise price of a stock option may be no less than 100% of the fair market value, as defined in the 2008 Plan, of the shares on the date of grant. At the time of grant, the Committee will have sole discretion in determining when stock options are exercisable and when they expire, except that the term of a stock option cannot exceed 10 years.

Stock Appreciation Rights (“SARs”) - The Committee may grant SARs as a right in tandem with the number of shares underlying stock options granted under the 2008 Plan or on a stand-alone basis. SARs are the right to receive payment per share of the SAR exercised in stock or in cash equal to the excess of the share’s fair market value, as defined in the 2008 Plan, on the date of exercise over its fair market value on the date the SAR was granted. Exercise of a SAR issued in tandem with stock options will result in the reduction of the number of shares underlying the related stock option to the extent of the SAR exercise.

Stock Awards, Restricted Stock, Restricted Stock Units, and Other Awards - The Committee may grant awards of restricted stock, restricted stock units, and other stock and cash-based awards, which may include the payment of stock in lieu of cash (including cash payable under other incentive or bonus programs) or the payment of cash (which may or may not be based on the price of our common stock).

Outside Director Stock Option Plan - In addition to the 2008 Plan discussed above, we have an Outside Director Stock Option Plan (the “Outside Director Plan”). The Outside Director Plan authorizes the grant of non-qualified stock options to each member of our Board of Directors who is not an officer or employee of LSB or its subsidiaries.

The Outside Director Plan also provides that each outside director may elect to receive all or any portion of his or her director fee for services rendered as a director of LSB in shares of LSB’s common stock, provided that the outside director elects to receive shares in payment of his or her director fee each calendar quarter.

Stock-Based Compensation - During 2014, the Committee approved the grants under the 2008 Plan of 489,000 shares of stock options (the “2014 Options”) to certain employees. The exercise price of the 2014 Options was equal to the market value of our common stock at the date of grant. The 2014 Options vest at the end of each one-year period at the rate of 16.5% per year for the first five years and the remaining unvested options will vest at the end of the sixth year. The 2014 Options expire in 2024. The fair value for the 2014 Options was estimated, using an option pricing model, as of the date of the grant, which date was also the service inception date. During 2013 and 2012, the Committee did not grant any awards under the 2008 Plan.

The fair value for the 2014 Options was estimated using a Black-Scholes-Merton option pricing model with the following assumptions:

• risk-free interest rate based on an U.S. Treasury zero-coupon issue with a term approximating the estimated expected life as of the grant date;

• a dividend yield based on historical data;

• volatility factors of the expected market price of our common stock based on historical volatility of our common stock primarily over approximately six years from the date of grant; and

• a weighted-average expected life of the options based on the historical exercise behavior of these employees and outside director, if applicable.

The following table summarizes information about these granted stock options:

	2014			2013			2012
Weighted-average risk-free interest rate		1.83	%		N/A			N/A

At December 31, 2014, the total stock-based compensation expense not yet recognized is $9,072,000 relating to non-vested stock options, which we will be amortizing (subject to adjustments for forfeitures) through the respective remaining vesting periods.

Stock Option Plans and Grants - At December 31, 2014, we have options outstanding under a 1998 Stock Option Plan (“1998 Plan”) and the 2008 Plan as discussed above. The 1998 Plan has expired, and accordingly, no additional options may be granted from the 1998 Plan. Options granted prior to the expiration of this plan continue to remain valid thereafter in accordance with their terms. The exercise price of the outstanding options granted under the 1998 and 2008 Plans was equal to the market value of our common stock at the date of grant.

The following information relates to our stock option plans:

	December 31, 2014

In addition to our stock option plans, in 2006 our stockholders approved the grant of 450,000 shares of stock options (the “2006 Options”) to certain Climate Control Business employees. The exercise price of the 2006 Options is $8.01 per share. At December 31, 2014, there were 120,000 options outstanding related to the 2006 Options, of which 30,000 are exercisable.

Preferred Share Rights Plan - On January 5, 2009, a renewed shareholder rights plan became effective upon the expiration of our previous shareholder rights plan. The rights plan will impact a potential acquirer unless the acquirer negotiates with our Board of Directors and the Board of Directors approves the transaction. Pursuant to the renewed plan, one preferred share purchase right (a “Right”) is attached to each currently outstanding or subsequently issued share of our common stock. Prior to becoming exercisable, the Rights trade together with our common stock. In general, if a person or group acquires or announces a tender or exchange offer for 15% or more of our common stock (except for the Golsen Group and certain other limited excluded persons), then the Rights become exercisable. Each Right entitles the holder (other than the person or group that triggers the Rights being exercisable) to purchase from us one one-hundredth of a share of Series 4 Junior Participating Preferred Stock, no par value (the “Preferred Stock”), at an exercise price of $47.75 per one one-hundredth of a share, subject to adjustment. If a person or group acquires 15% or more of our common stock, each Right will entitle the holder (other than the person or group that triggered the Rights being exercisable) to purchase shares of our common stock (or, in certain circumstances, cash or other securities) having a market value of twice the exercise price of a Right at such time. Under certain circumstances, each Right will entitle the holder (other than the person or group that triggered the Rights being exercisable) to purchase the common stock of the acquirer having a market value of twice the exercise price of a Right at such time. In addition, under certain circumstances, our Board of Directors may exchange each Right (other than those held by the acquirer) for one share of our common stock, subject to adjustment. Our Board of Directors may redeem the Rights at a price of $0.01 per Right generally at any time before 10 days after the Rights become exercisable. Our Board of Directors may exchange all or part of the Rights (except to the person or group that triggered the Rights being exercisable) for our common stock at an exchange ratio of one common share per Right until the person triggering the Right becomes the beneficial owner of 50% or more of our common stock.

Other – As of December 31, 2014, we have reserved 1.9 million shares of common stock issuable upon potential conversion of preferred stocks and stock options pursuant to their respective terms.
