Stock-Based Compensation

2. Stock-Based Compensation

Equity Incentive Plan. Lamar Advertising’s 1996 Equity Incentive Plan, as amended (the “Incentive Plan”) has reserved 15.5 million shares of Class A common stock for issuance to directors and employees, including shares underlying granted options and common stock reserved for issuance under its performance-based incentive program. Options granted under the plan expire ten years from the grant date with vesting terms ranging from three to five years and include 1) options that vest in one-fifth increments beginning on the grant date and continuing on each of the first four anniversaries of the grant date and 2) options that cliff-vest on the fifth anniversary of the grant date. All grants are made at fair market value based on the closing price of our Class A common stock as reported on the NASDAQ Global Select Market on the date of grant.

We use a Black-Scholes-Merton option pricing model to estimate the fair value of share-based awards. The Black-Scholes-Merton option pricing model incorporates various and highly subjective assumptions, including expected term and expected volatility. The Company granted options for an aggregate of 14,000 shares of its Class A common stock during the three months ended March 31, 2014.

Stock Purchase Plan. In 2009 our Board of Directors adopted a new employee stock purchase plan, the 2009 Employee Stock Purchase Plan or 2009 ESPP, which was approved by our shareholders on May 28, 2009. The 2009 ESPP reserved 588,154 shares of Class A common stock for issuance to our employees, which included 88,154 shares of Class A common stock that had been available for issuance under our 2000 Employee Stock Purchase Plan or 2000 ESPP. The 2000 ESPP was terminated following the issuance of all shares that were subject to the offer that commenced under the 2000 ESPP on January 1, 2009 and ended June 30, 2009. The terms of the 2009 ESPP are substantially the same as the 2000 ESPP.

The number of shares of Class A common stock available under the 2009 ESPP was automatically increased by 80,209 shares on January 1, 2014 pursuant to the automatic increase provisions of the 2009 ESPP.

The following is a summary of 2009 ESPP share activity for the period ended March 31, 2014:


	Shares
Available for future purchases, January 1, 2014		327,689
Additional shares reserved under 2009 ESPP		80,209
Purchases		(29,590	)

Available for future purchases, March 31, 2014		378,308

Performance-based compensation. Unrestricted shares of our Class A common stock may be awarded to key officers, employees and directors under our 1996 Equity Incentive Plan. The number of shares to be issued, if any, will be dependent on the level of achievement of performance measures for key officers and employees, as determined by the Company’s Compensation Committee based on our 2014 results. Any shares issued based on the achievement of performance goals will be issued in the first quarter of 2015. The shares subject to these awards can range from a minimum of 0% to a maximum of 100% of the target number of shares depending on the level at which the goals are attained. For the three months ended March 31, 2014, the Company has recorded $1,423 as non-cash compensation expense related to performance based awards. In addition, each non-employee director automatically receives upon election or re-election a restricted stock award of our Class A common stock. The awards vest 50% on grant date and 50% on the last day of each director’s one-year term. The Company recorded $31 as non-cash compensation expense related to these non-employee director awards for the three months ended March 31, 2014.

Summarized Financial Information of Subsidiaries Separate financial statements of each of the Company’s direct or indirect wholly owned subsidiaries that have guaranteed Lamar Media’s obligations with respect to its publicly issued notes (collectively, the “Guarantors”) are not included herein because the Company has no independent assets or operations, the guarantees are full and unconditional and joint and several and the only subsidiaries that are not guarantors are in the aggregate minor. Lamar Media’s ability to make distributions to Lamar Advertising is restricted under both the terms of the indentures relating to Lamar Media’s outstanding notes and by the terms of the senior credit facility. As of March 31, 2014 and December 31, 2013, Lamar Media was permitted under the terms of its outstanding senior subordinated notes to make transfers to Lamar Advertising in the form of cash dividends, loans or advances in amounts up to $2,140,551 and $2,072,542, respectively. Transfers to Lamar Advertising are permitted under Lamar Media’s senior credit facility and as defined therein, unless, after giving effect such distributions, (i) the total debt ratio is equal to or greater than 5.75 to 1 or (ii) the senior debt ratio is equal to or greater than 3.25 to 1. As of March 31, 2014, the total debt ratio was less than 5.75 to 1 and Lamar Media’s senior debt ratio was less than 3.25 to 1; therefore, dividends or distributions to Lamar Advertising were not subject to any additional restrictions under the senior credit facility.

Senior Credit Facility

On January 10, 2014, Lamar Media paid in full the outstanding balance of the term loans then outstanding under its senior credit facility.

On February 3, 2014, Lamar Media entered into a Second Restatement Agreement (the “Second Restatement Agreement”) with the Company, certain of Lamar Media’s subsidiaries as Guarantors, JPMorgan Chase Bank, N.A., as Administrative Agent and the Lenders named therein, under which the parties agreed to amend and restate Lamar Media’s existing senior credit facility on the terms set forth in the Second Amended and Restated Credit Agreement attached as Exhibit A to the Second Restatement Agreement (such Second and Amended and Restated Credit Agreement together with the Second Restatement Agreement being herein referred to as the “senior credit facility”). The senior credit facility consists of a $400,000 revolving credit facility and a $500,000 incremental facility. Lamar Media is the borrower under the senior credit facility. We may also from time to time designate wholly-owned subsidiaries as subsidiary borrowers under the incremental loan facility. Incremental loans may be in the form of additional term loan tranches or increases in the revolving credit facility. Our lenders have no obligation to make additional loans to us, or any designated subsidiary borrower, under the incremental facility, but may enter into such commitments in their sole discretion.

As of March 31, 2014, there were no amounts outstanding under the revolving credit facility. Availability under the revolving facility is reduced by the amount of any letters of credit outstanding. Lamar Media had $6,973 letters of credit outstanding as of March 31, 2014 resulting in $393,027 of availability under its revolving facility. Revolving credit loans may be requested under the revolving credit facility at any time prior to its maturity on February 2, 2019, and bear interest, at Lamar Media’s option, at the Adjusted LIBOR Rate or the Adjusted Base Rate plus applicable margins, such margins are set at an initial rate with the possibility of a step down based on Lamar Media’s ratio of debt to trailing four quarters EBITDA, as defined in the senior credit facility.

The terms of Lamar Media’s senior credit facility and the indentures relating to Lamar Media’s outstanding notes restrict, among other things, the ability of Lamar Advertising and Lamar Media to:

•

dispose of assets;

•

incur or repay debt;

•

create liens;

•

make investments; and

•

pay dividends.

The senior credit facility contains provisions that would allow Lamar Media to conduct its affairs in a manner that would allow Lamar Advertising to qualify and remain qualified as a REIT, including by allowing Lamar Media to make distributions to Lamar Advertising required for the Company to qualify and remain qualified for taxation as a REIT, subject to certain restrictions.

Lamar Media’s ability to make distributions to Lamar Advertising is also restricted under the terms of these agreements. Under Lamar Media’s senior credit facility the Company must maintain a specified senior debt ratio at all times and in addition, must satisfy a total debt ratio in order to incur debt, make distributions or make certain investments.

Lamar Advertising and Lamar Media were in compliance with all of the terms of their indentures and the applicable senior credit agreement provisions during the periods presented.

Fair Value of Financial Instruments	9. Fair Value of Financial Instruments At March 31, 2014 and December 31, 2013, the Company’s financial instruments included cash and cash equivalents, marketable securities, accounts receivable, investments, accounts payable and borrowings. The fair values of cash and cash equivalents, accounts receivable, accounts payable and short-term borrowings and current portion of long-term debt approximated carrying values because of the short-term nature of these instruments. Investment contracts are reported at fair values. Fair values for investments held at cost are not readily available, but are estimated to approximate fair value. The estimated fair value of the Company’s long term debt (including current maturities) was $2,011,087 which exceeded the carrying amount of $1,946,761 as of March 31, 2014.

Accounting Changes And Error Corrections [Abstract]
Adjustments to Previously Reported Amounts	10. Adjustments to Previously Reported Amounts Immaterial Correction of an Error. Commencing with the fourth quarter of 2013, the Company revised previously reported amounts due to a change from recognizing revenue on a monthly basis over the term of the advertising contract to recognizing revenue on a daily basis over the term of the advertising contract. In accordance with Staff Accounting Bulletin (“SAB”) No. 99, Materiality, and SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, management evaluated the materiality of the error from qualitative and quantitative perspectives, and concluded the error was immaterial to the current and prior periods. The correction of the immaterial error resulted in a reduction of net revenue and net income of $6,874 and $4,193, respectively, for the three months ended March 31, 2013. The correction also resulted in a decrease of $0.04 in earnings per basic and dilutive share for the three months ended March 31, 2013. The Company revised its historical financial statements as published in our 2013 Combined 10-K for fiscal 2011 and 2012, and the three months ended March 31, 2013 contained therein. The Company will revise the quarters ended June 30, 2013 and September 30, 2013, when they are published in future filings.

On April 18, 2014, Lamar Media entered into Amendment No. 1 to the Second Amended and Restated Credit Agreement (the “Amendment”) with Lamar Advertising, certain of Lamar Media’s subsidiaries as Guarantors, JPMorgan Chase Bank, N.A. as Administrative Agent and the Lenders named therein under which the parties agreed to amend Lamar Media’s existing senior credit facility on the terms set forth in the Amendment. The Amendment created a new $300,000 Term A Loan facility (the “Term A Loans”) and certain other amendments to the senior credit agreement. The Term A Loans are not incremental loans and do not reduce the existing $500,000 Incremental Loan facility. Lamar Media borrowed all $300,000 in Term A Loans on April 18, 2014. The net loan proceeds, together with borrowings under the revolving portion of the senior credit facility and cash on hand, were used to fund the redemption of all $400,000 in aggregate principal amount of Lamar Media’s 7 7/8% Senior Subordinated Notes due 2018 on April 21, 2014.

The Term A Loans mature on February 2, 2019 and will begin amortizing on June 30, 2014 in quarterly installments paid on such date and on each September 30, December 31, March 31 and June 30 thereafter, as follows:


Principal Payment Date	Principal Amount
June 30, 2014-March 31, 2016	$	3,750,000
June 30, 2016- March 31, 2017	$	5,625,000
June 30, 2017-December 31, 2018	$	11,250,000
Term A Loan Maturity Date	$	168,750,000

The Term A Loans bear interest at rates based on the Adjusted LIBO Rate (“Eurodollar Term A Loans”) or the Adjusted Base Rate (“Base Rate Term A Loans”), at Lamar Media’s option. Eurodollar Term A Loans bear interest at a rate per annum equal to the Adjusted LIBO Rate plus 2.00% (or the Adjusted LIBO Rate plus 1.75% at any time the Total Debt Ratio is less than or equal to 3.00 to 1). Base Rate Term A Loans bear interest at a rate per annum equal to the Adjusted Base Rate plus 1.00% (or the Adjusted Base Rate plus 0.75% at any time the Total Debt Ratio is less than or equal to 3.00 to 1). The guarantees, covenants, events of default and other terms of the senior credit facility apply to the Term A Loans.

On April 23, 2014, the Company received its requested private letter ruling from the U.S. Internal Revenue Service (the “IRS”) regarding certain matters relevant to its intended election to be taxed as a real estate investment trust (REIT) under the Internal Revenue Code of 1986, as amended (the “Code”). As previously announced, the Company intends to make an election under §1033(g)(3) of the Code to treat its outdoor advertising displays as real property for tax purposes. The private letter ruling confirms, among other matters, that the Company’s income from renting space on such outdoor advertising displays qualifies as rents from real property for REIT purposes. The Company’s conversion to REIT status is expected to be effective as of January 1, 2014, subject to final approval of the Company’s board of directors.
