Employee Stock Purchase Plan

Under the Company’s amended and restated Qualified Employee Stock Purchase Plan, a total of 10,000,000 shares of common stock are available for issuance. As currently administered by the Company’s compensation committee, all full-time employees may use a portion of their salary to acquire shares of LTS common stock under this purchase plan at a 5% discount from the market price of LTS’ common stock at the end of each option period. Option periods have been set at three month periods and commence on January 1, April 1, July 1, and October 1 of each year and end on March 31, June 30, September 30 and December 31 of each year. The plan is intended to qualify as an “employee stock purchase plan” under Section 423 of the Internal Revenue Code. During 2015, 192,978 shares of LTS common stock were issued to employees under this plan, at prices ranging from $2.00 to $3.67; during 2014, 89,581 shares of LTS common stock were issued to employees under this plan, at prices ranging from $2.87 to $4.03; and during 2013, 112,646 shares of LTS common stock were issued to employees under this plan, at prices ranging from $1.57 to $2.97. These share issuances resulted in a capital contribution of $545, $291 and $201 for 2015, 2014 and 2013, respectively.

Amended and Restated 1999 Performance Equity Plan and 2009 Incentive Compensation Plan

In 1999, the Company adopted the 1999 Performance Equity Plan (as amended and restated, the “1999 Plan”) and in 2009 the Company adopted the 2009 Incentive Compensation Plan (the “2009 Plan”), which provide for the grant of stock options and other awards to designated employees, officers and directors and certain other persons performing services for the Company and its subsidiaries, as designated by the board of directors. The 1999 Plan provides for the granting of up to 25,000,000 awards with an annual limit on grants to any individual of 1,500,000. In 2014, the 2009 Plan was amended to provide for the granting of up to 45,000,000 awards with an annual limit on grants to any individual of 1,500,000. Awards under the plans include stock options, stock appreciation rights, restricted stock, deferred stock, stock reload options and/or other stock-based awards. The compensation committee of the Company’s board of directors administers the plans. Stock options granted under the 2009 Plan may be incentive stock options and non-qualified stock options. An incentive stock option may be granted only through August 27, 2019 under the 2009 Plan and may only be exercised within ten years of the date of grant (or five years in the case of an incentive stock option granted to an optionee who at the time of the grant possesses more than 10% of the total combined voting power of all classes of stock of LTS (“10% Shareholder”)). Incentive stock options may no longer be granted under the 1999 Plan. The exercise price of both incentive and non-qualified options may not be less than 100% of the fair market value of LTS’ common stock at the date of grant, provided, that the exercise price of an incentive stock option granted to a 10% Shareholder shall not be less than 110% of the fair market value of LTS’ common stock at the date of grant. As of December 31, 2015, 20,009,745 and 1,244,354 shares of common stock were available for issuance under the 2009 Plan and the 1999 Plan, respectively.

Non-Plan Options

The Company has granted stock options to newly-hired employees in conjunction with their employment agreements or in connection with acquisitions, which are outside of the option plans. A summary of the status of these options at December 31, 2015 and changes during the year ended December 31, 2015 are presented below:



	Shares	Weighted- Average Exercise Price		Weighted- Average Remaining Contractual Term (Years)	Aggregate Intrinsic Value
Options outstanding, December 31, 2014	4,415,000	$	1.63
Exercised	—	—
Options outstanding, December 31, 2015	4,415,000	$	1.63	1.45	$	4,970
Vested or expected to vest, December 31, 2015	4,415,000	$	1.63	1.45	$	4,970
Options exercisable, December 31, 2015	4,415,000	$	1.63	1.45	$	4,970

The weighted-average grant date fair value of employee and director options granted during the years ended December 31, 2015, 2014 and 2013 was $2.79, $1.85 and $0.74, respectively. The fair value of each option award was estimated on the date of grant using the Black-Scholes option pricing model using the following weighted-average assumptions:



	Year Ended December 31,
	2015		2014		2013
Dividend yield	—	%	—	%	—	%
Expected volatility	61.10	%	64.94	%	65.66	%
Risk-free interest rate	1.63	%	2.02	%	1.17	%
Expected life (in years)	6.15		6.4		6.2

The weighted average expected life for the 2015, 2014 and 2013 grants to employees and directors reflects the alternative simplified method permitted by authoritative guidance, which defines the expected life as the average of the contractual term of the options and the weighted-average vesting period for all option tranches. The Company estimates the expected term for stock options awarded to independent financial advisors using the contractual term. Expected volatility for the 2015 option grants is based on the historical volatility of the common stock of the Company over the same number of years as the expected life, prior to the option grant date. Expected volatility in 2014 and 2013 was based on blended volatility comprised of the historical volatility of the common stock of the Company and its peers over the same number of years as the expected life, prior to the option grant date.

Restricted Stock Awards

A summary of the restricted stock awards at December 31, 2015 and changes during the years ended December 31, 2015 and 2014 are presented below:



	Restricted Stock		Weighted-Average Grant Date Fair Value Per Share
Nonvested at December 31, 2012 and 2013	—		$	—
Issued during 2014	14,409		3.44
Nonvested at December 31, 2014	14,409		3.44
Issued during 2015	1,206,081		3.92
Vested during 2015	(11,948	)	3.48
Nonvested at December 31, 2015	1,208,542		3.91

Restricted stock awards issued in 2015 vest in four equal annual installments.

As of December 31, 2015, there was $9,632 of total unrecognized compensation cost related to non-vested share-based compensation arrangements. This cost is expected to be recognized over the vesting periods of the options and restricted stock, which on a weighted-average basis is approximately 1.97 years.

The total intrinsic value of options exercised during the years ended December 31, 2015, 2014 and 2013 amounted to $2,595,$4,640 and $957, respectively. The fair value of restricted stock vested in 2015 was $42.

Non-cash compensation expense relating to stock options was calculated using the Black-Scholes option pricing model, amortizing the value calculated over the vesting period and applying a forfeiture percentage as estimated by the Company’s management, using historical information. The Company has elected to recognize compensation cost for option awards that have graded vesting schedules on a straight line basis over the requisite service period for the entire award.

For the years ended December 31, 2015, 2014 and 2013, non-cash compensation expense relating to share-based awards granted to employees, consultants and advisors amounted to $8,759, $10,541 and $6,766, respectively.
