REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Plan Administrator, Investment Committee and the Audit Committee

Sinclair Broadcast Group, Inc. 401(k) Retirement Savings Plan

We have audited the accompanying statement of net assets available for benefits of Sinclair Broadcast Group 401(k) Retirement Savings Plan (the “Plan”) as of December 31, 2012, and the related statement of changes in net assets available for benefits for the year then ended. These financial statements are the responsibility of the Plan’s management.  Our responsibility is to express an opinion on these financial statements based on our audit.

We conducted our audit in accordance with the standards of the Public Company Accounting Oversight Board (United States).  Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement.  The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting.  Our audit included consideration of internal control over financial reporting as a basis for designing audit procedures that are appropriate in the circumstances, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting.  Accordingly, we express no such opinion.  An audit also includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements, assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audit provides a reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2012 and the changes in net assets available for benefits for the year then ended, in conformity with accounting principles generally accepted in the United States of America.

Our audit was performed for the purpose of forming an opinion on the basic financial statements taken as a whole. The supplemental schedule of assets (held at end of year) as of December 31, 2012, is presented for the purpose of additional analysis and is not a required part of the basic financial statements but is supplementary information required by the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974.  This supplemental schedule is the responsibility of the Plan’s management. The supplemental schedule has been subjected to the auditing procedures applied in the audit of the basic financial statements and, in our opinion, is fairly stated in all material respects in relation to the basic financial statements taken as a whole.

NOTES TO FINANCIAL STATEMENTS

December 31, 2012 and 2011

NOTE 1 - PLAN DESCRIPTION

The following description of Sinclair Broadcast Group, Inc. 401(k) Retirement Savings Plan (the “Plan”) provides only general information.  Participants should refer to the Summary Plan Description for a more complete description of the Plan’s provisions.  Copies of this summary are available from Sinclair Broadcast Group, Inc. (the “Company” or “Employer”), Human Resources Department.

General

The Plan was adopted on January 1, 1988 and was amended and restated effective April 14, 2010 pursuant to a Massachusetts Mutual Life Insurance Company (“Mass Mutual”) Non-standardized 401(k) Profit Sharing Plan Prototype Plan Document.  The Plan is a participatory defined contribution plan covering substantially all of the Company’s employees. Mass Mutual is the trustee and administrator of the Plan and distributes the funds in accordance with the Plan documents.  An employee is eligible to participate in the Plan upon successful completion of the introductory period (90-day evaluation period to which all new employees and re-hires are subject).  Re-hires, if eligible to participate in the Plan on their date of termination, are eligible to enter the Plan on the date of re-hire.  Although employees may participate in the Plan, they will not be eligible to receive the discretionary company match until they have completed one year of service.  An employee will earn a year of service if they work at least 1,000 hours during the 12-month period immediately following their date of hire or if they work at least 1,000 hours during any Plan year beginning after their date of hire.  In addition, once a participant completes a year of service in order to receive the discretionary match, they must also be employed on the last day of the Plan year and complete at least 1,000 hours of service during the Plan year for which the match pertains.  On October 1, 2012, the Plan was amended to implement an auto enrollment process whereby participants are automatically enrolled at a 3% deferral rate upon becoming eligible.  The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”).

December 31, 2012 and 2011

Contributions

Employees contribute to the Plan through payroll deductions, up to a maximum of 98% of their total compensation.  Each participant’s account is credited with the participant’s contribution, matching contribution, and their pro rata share of earnings or losses on invested assets of the trust funds.  The Company’s matching contribution for all participating employees is discretionary and during 2012, was equal to 50% of the employees’ contributions limited to the first 4% of compensation the employee contributed.  Contributions to the Plan are invested in the available investment options in accordance with the participant’s election.  A terminating member of the Plan has the option to maintain their account (if the balance is over $5,000) or be paid the current value of their contributions and any vested employer contributions to the Plan, reduced by any outstanding loan balances.

The terminating member must forfeit the current unvested value of the Employer’s contribution to their account.  In accordance with the terms of the Plan, such forfeitures are first applied to pay administrative expenses of the Plan, if any, and then to reduce future contributions required of the Employer.  Participants are fully vested in their contribution to the Plan and related earnings.  Under the provisions of the Plan, eligible employees become 20% vested in employer contribution amounts credited to their account after two years of service, 40% vested after three years of service, 60% vested after four years of service, 80% vested after five years of service and 100% vested after six years of service.

Unallocated assets which consist of forfeited amounts in the Plan were $79,089 and $56,103 as of December 31, 2012 and 2011, respectively. During 2012, $56,423 of forfeitures were used to fund employer contributions. Unallocated assets are invested in the guaranteed investment contract.

The December 31, 2012 and 2011 Employer contributions consist of a receivable that was funded subsequent to the Plan’s year end with the Company’s common stock.  The Company may also make additional discretionary profit sharing contributions each year.  There were no additional discretionary contributions during 2012 and 2011.

Upon enrollment, a participant may direct employee contributions to any of the Plan’s available fund options except the Sinclair Broadcast Group Common Stock Fund.  Employer contributions are invested in the Sinclair Broadcast Group, Inc. Common Stock Fund, but may be redirected by participants to other fund options immediately.

December 31, 2012 and 2011

In 2012, the Company hired employees in connection with the acquisition of television stations, and the execution of shared services agreements with certain third-party owned television stations.  Upon hire, these employees were immediately eligible to participate in the Plan and were credited with service earned while employed by these television station owners.

Excess Contributions Refundable

As of December 31, 2012 and 2011, a refund of contributions plus related investment earnings, totaling $162,323 and $223,531, respectively, has been recorded as a liability to certain employees in order to pass the Actual Deferral Percentage test under Section 401(a) of the Internal Revenue Code (“IRC”).

Payment of Benefits

Participants may elect one of several methods to receive their vested benefits including: (a) a joint and survivor option whereby the employee receives a reduced monthly benefit during his/her lifetime and, upon death, the surviving spouse will receive a monthly benefit for his/her lifetime; (b) the purchase of a life annuity; (c) equal installments over a period of not more than the participant’s assumed life expectancy (or participant’s and participant’s beneficiary’s assumed life expectancy) at the time of distribution; (d) a lump sum distribution; or (e) partial distributions.  In the absence of such election by the participant, the method of distribution shall be determined by the Plan.  Upon termination of employment before normal retirement, a lump sum distribution may also be made.

Participant Notes Receivable

Participants have the option to borrow from the vested portion of their account.  The minimum loan amount is $1,000 and the maximum loan permitted is the lesser of: (1) $50,000; or (2) one-half of their vested balance, and is secured by the balance in the participant’s account with interest charged based on the prime rate at the time of borrowing plus 1%.  The rates charged to participants on current loans outstanding ranged from 4.25% to 10.50% as of both December 31, 2012 and 2011.  Participants may have two loans outstanding at one time.  Generally, the term of the loans may not exceed five years.  Interest income from these loans is treated as income to the Plan.  Principal and interest are paid ratably through monthly payroll deductions.

Plan Termination

Although the Company has not expressed any intent to do so, the Company has the right under the Plan to discontinue contributions at any time and to terminate the Plan subject to the provisions of ERISA.  In the event of Plan termination, participants will become 100% vested in their accounts.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Use of Estimates

The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts in the financial statements and accompanying notes.  Actual results could differ from those estimates.

Basis of Accounting

The accompanying financial statements are presented on the accrual basis of accounting. Certain administrative expenses are borne by Sinclair Broadcast Group, Inc.  The Company has evaluated subsequent events for recognition and disclosure through the date of this filing.

Investment Valuation and Income Recognition

The Plan’s investments are stated at fair value.  For further information see Note 3 Fair Value Measurements.

The Plan is invested in a guaranteed investment contract that qualifies as a fully benefit-responsive investment contract.  As described in the accounting guidance, the investment contracts held by a defined contribution plan are required to be reported at fair value.  However, contract value is the relevant measurement attribute for that portion of the net assets available for benefits for a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan.  As required by accounting guidance, the statements of net assets available for benefits presents the fair value of the investment contracts as well as the adjustment of the fully benefit-responsive investment contracts from fair value to contract value basis.

NOTES TO FINANCIAL STATEMENTS - CONTINUED

December 31, 2012 and 2011

Purchases and sales of securities are recorded on a trade-date basis. The net appreciation of the fair value of investments consists of realized and unrealized gains and losses and dividends.  Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date.

Participant notes receivable

Notes receivable from participants are valued at the outstanding principal balance plus accrued interest, which represents the exit value upon collection, either by repayment or by deemed distribution if not repaid.

Benefit Payments

Benefit payments are recorded when paid.

NOTE 3 – FAIR VALUE MEASUREMENTS

Accounting guidance provides for valuation techniques, such as the market approach (comparable market prices), the income approach (present value of future income or cash flow), and the cost approach (cost to replace the service capacity of an asset or replacement cost).  A fair value hierarchy using three broad levels prioritizes the inputs to valuation techniques used to measure fair value.  The following is a brief description of those three levels:

·Level 1: Observable inputs such as quoted prices (unadjusted) in active markets for identical assets or liabilities;

·Level 2: Inputs other than quoted prices that are observable for the asset or liability, either directly or indirectly. These include quoted prices for similar assets or liabilities in active markets and quoted prices for identical or similar assets or liabilities in markets that are not active; or

·Level 3: Unobservable inputs that reflect the reporting entity’s own assumptions.

Pooled Separate Accounts

The fair value of the participation units owned by the Plan in the pooled separate accounts is based on the net assets of the underlying pool of securities on the last business day of the Plan year as determined by Mass Mutual.

Guaranteed Investment Contract

Investment contracts are presented at fair value.  The fair value of the Plan’s interest in a guaranteed investment contract is based upon the fair value of the fund’s

401(k) Retirement Savings Plan

NOTES TO FINANCIAL STATEMENTS - CONTINUED

December 31, 2012 and 2011

underlying managed group annuity contract, as reported by the insurance company issuer of the contract.  Contract value represents contributions and reinvested income, less any withdrawals, plus accrued interest, because these investments have fully benefit-responsive features.  Under certain conditions, participants may receive less than the contract value of their accounts invested in the investment contracts, as determined by Mass Mutual, the Plan’s administrator.  As of December 31, 2012, there were no reserves against contract values for credit risk of contract issuers or otherwise.  The interest rate was 2.42% and 2.79% as of December 31, 2012 and 2011, respectively.

Common Stock Fund

The Sinclair Broadcast Group, Inc. Common Stock Fund (the “Fund”) is tracked on a unitized basis.  The Fund consists of the Company’s common stock which is valued at its quoted market price and funds held in the Investors Bank and Trust Money Market Fund sufficient to meet the Fund’s daily cash needs.  The Fund is unitized to allow for daily trades.  The value of a unit reflects the combined market value of the Company’s common stock and the cash investments held by the Fund.  As of December 31, 2012, 900,318 units were outstanding with a value of $12.62 per unit.  As of December 31, 2011, 782,572 units were outstanding with a value of $11.33 per unit.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values.  Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

NOTE 4 - INVESTMENTS

During 2012, the Plan’s investments (including investments purchased, sold, as well as held during the year) appreciated in aggregate fair value as follows:

The SF Guaranteed Interest Fund is required to be reported at fair value.  However, contract value is relevant measurement attribute for that portion of net assets available for benefits because contract value is the amount participants would receive if they were to initiate permitted transactions under the terms of the Plan.  See Note 6 for additional information.

NOTE 5 - INCOME TAX STATUS

The underlying non-standardized prototype plan has received an opinion letter from the Internal Revenue Service (“IRS”) dated May 11, 2009 stating that the form of the Plan is qualified under Section 401 of the IRC and, therefore, the related trust is tax-exempt.  In accordance with Revenue Procedure 2002-6 and Announcement 2001-77, the Plan sponsor has determined that it is eligible to, and has chosen to, rely on the current IRS prototype plan opinion letter.  Once qualified, the Plan is required to operate in conformity with the IRC to maintain its qualification.  The Plan administrator believes the Plan is being operated in compliance with the applicable requirements of the IRC and, therefore, believes that the Plan is qualified and the related trust is tax-exempt.

Accounting principles generally accepted in the United States of America require plan management to evaluate tax positions taken by the plan and recognize a tax liability if the plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress. The Plan administrator believes it is no longer subject to income tax examinations for years prior to 2009.

NOTE 6 – FULLY BENEFIT-RESPONSIVE INVESTMENT CONTRACT OF GUARANTEED INVESTMENT CONTRACT

Mass Mutual’s general investment account investment option for defined contribution plans is provided through a group annuity contract which the Plan is invested in.  Under the terms of a group annuity contract, a crediting rate is established for amounts invested in the guaranteed interest account and participants may direct permitted withdrawal and/or transfer transactions of all or a portion of their account balance at contract value. Contract value represents contributions plus credited interest less participant withdrawals and fees.  The Plan considers this investment option to be fully benefit-responsive notwithstanding the liquidation value events under the contract that limit the ability of the Plan to transact at contract value.  The fair value presented in Note 3 represents the estimated liquidation value determined within contract specifications (see the termination provisions stated within the contract).

The average yield earned is calculated by dividing the annual interest credited to the Plan during the Plan year by the average annual fair value. The average interest rate credited to participants is calculated by dividing the annual interest credited to the participants during the Plan year by the average annual fair value. The average yield earned by the Plan and the average interest rate credited to participants is the same, therefore, no adjustment is needed.  The average yield earned by the Plan and average interest rate credited to participants were both 2.42% and 2.79% for 2012 and 2011, respectively.

Certain events may limit the ability of the Plan to transact at contract value. Such events include but may not be limited to the following: (1) temporary absence; (2) change in position or other occurrence qualifying as a temporary break in service under the Plan; (3) transfer or other change of position resulting in employment by an entity controlling, controlled by, or under other common control with the employer; (4) cessation of an employment relationship resulting from a reorganization, merger, layoff or the sale or discontinuance of all or any part of the Plan sponsor’s business; (5) removal from the Plan of one or more groups or classifications of participants; (6) partial or complete Plan termination; or (7) Plan disqualification.
