Note 1. Basis of Presentation

In the opinion of management the accompanying unaudited financial statements contain all adjustments (consisting of only normal recurring adjustments) necessary for a fair presentation of the results for such periods. The results for any interim period are not necessarily indicative of the results to be expected for the full fiscal year. Certain information and footnote disclosures normally included in financial statements prepared in accordance with United States generally accepted accounting principles have been condensed or omitted. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of assets and liabilities. On an ongoing basis, we evaluate our estimates and judgments, including those related to revenue recognition, inventories, income taxes, and stock-based compensation. Management bases its estimates on historical experience and on various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions. These financial statements should be read in conjunction with the Company's most recent audited financial statements included in its report on Form 10-K for the year ended June 30, 2013. Certain reclassifications may have been made to the prior year financial statements to conform to the current year presentation.

Net Income per Share

Note 2. Net Income per Share

Basic net income per share excludes dilution and is computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the potential dilution that could occur if securities or other contracts to issue common stock were exercised or converted into common stock or resulted in the issuance of common stock that then shared in the income of the Company. As Unearned ESOP shares are released or committed-to-be-released the shares become outstanding for earnings-per-share computations.

Stock Based Compensation

Note 3. Stock Based Compensation

The Company follows ASC 718 in establishing standards for the accounting for transactions in which an entity exchanges its equity instruments for goods or services, as well as transactions in which an entity incurs liabilities in exchange for goods or services that are based on the fair value of the entity’s equity instruments or that may be settled by the issuance of those equity instruments. ASC 718 requires that the cost resulting from all share-based payment transactions be recognized in the financial statements based on the fair value of the share-based payment. ASC 718 establishes fair value as the measurement objective in accounting for share-based payment transactions with employees, except for equity instruments held by employee share ownership plans.

Total stock-based compensation expense recognized in the statements of comprehensive income for the three-month period ended December 31, 2013 and 2012, was $25,478 and $27,405, respectively, before income taxes. The related total deferred tax benefit was approximately $2,774 and $3,116 for the three-month period ended December 31, 2013 and 2012, respectively. Total stock-based compensation expense recognized in the statements of comprehensive income for the six-month period ended December 31, 2013 and 2012, was $52,243 and $60,371, respectively, before income taxes. The related total deferred tax benefit was approximately $5,779 and $6,736 for the six-month period ended December 31, 2013 and 2012, respectively. ASC 718 requires the tax benefits resulting from tax deductions in excess of the compensation cost recognized for those options to be classified and reported as both an operating cash outflow and a financing cash inflow.

As of December 31, 2013, there was approximately $107,609 of unrecognized compensation cost related to stock option awards that is expected to be recognized as expense over the next 1.75 years. The total deferred tax benefit related to these awards is approximately $11,477.

The Company has one employee stock option plan under which options may be granted, the 2007 Stock Option and Restricted Stock Plan (the "2007 Plan"). The Board of Directors may grant options to acquire shares of common stock to employees of the Company at the fair market value of the common stock on the date of grant. Generally, options granted have a two-year vesting period based on two years of continuous service and have a ten-year contractual life. Option grants provide for accelerated vesting if there is a change in control. Shares issued upon the exercise of options are from those held in Treasury. The 2007 Plan was approved by the Company's shareholders at the Company's Annual Meeting on November 30, 2007 and supersedes the Company's 2000 Stock Option Plan (the "2000 Plan"). Options covering 400,000 shares were authorized for issuance under the 2007 Plan, of which 190,100 have been granted and 147,000 are outstanding as of December 31, 2013. While no further grants of options may be made under the 2000 Plan, as of December 31, 2013, 32,730 options remain outstanding, vested and exercisable from the 2000 Plan.

ASC 718 requires the use of a valuation model to calculate the fair value of stock-based awards. The Company has elected to use the Black-Scholes option valuation model, which incorporates various assumptions including those for volatility, expected life and interest rates.

The table below outlines the weighted average assumptions that the Company used to calculate the fair value of the option award for the six-months ended December 31, 2013. There were no options awarded for the six-months ended December 31, 2012.

 

    December 31, 2013  
Dividend yield     3.67%
Expected stock price volatility     25.31%
Risk-free interest rate     1.23%
Expected option life (in years)     3.8 yrs  
Weighted average fair value per share of options granted during the period   $ 3.777  

 

The Company pays dividends quarterly and has paid a special cash dividend of $1.00 per share in each of fiscal years 2014 and 2013. Our Board of Directors assesses the Company’s dividend policy periodically and we anticipate that regular quarterly dividends will be paid for the foreseeable future. There is no assurance, however, that the Board of Directors will either maintain the amount of the regular cash dividend or declare a special dividend during any future years. Expected stock price volatility is based on the historical volatility of the Company’s stock. The risk-free interest rate is based on the implied yield available on U.S. Treasury issues with an equivalent term approximating the expected life of the options. The expected option life (in years) represents the estimated period of time until exercise and is based on actual historical experience.

The following table summarizes stock option activity during the six-months ended December 31, 2013:

 

    Employee Stock Options Plan
            Weighted    
    Number of   Weighted   Average    
    Shares   Average   Remaining   Aggregate

Outstanding at December 31, 2013     179,730     $ 22.30       6.49     $ 1,858,401  
Vested or expected to vest at December 31, 2013     171,734     $ 22.12       6.37     $ 1,806,917  
Exercisable at December 31, 2013     118,780     $ 20.28       5.18     $ 1,468,178  

 

The aggregate intrinsic value in the table above represents the total pretax intrinsic value (the difference between the closing sale price of the Company’s common stock as reported on the NYSE MKT on December 31, 2013 and the exercise price, multiplied by the number of in-the-money options) that would have been received by the option holders if all option holders had exercised their options on December 31, 2013. This amount changes based on the fair market value of the Company’s common stock. The total intrinsic values of the options exercised during the six-months ended December 31, 2013 and 2012 was $68,729 and $52,999, respectively.

The following table summarizes changes in non-vested stock options during the three-months ended December 31, 2013:

Note 4. Commitments and Contingencies

The Company at certain times enters into standby letters of credit agreements with financial institutions primarily relating to the guarantee of future performance on certain contracts. Contingent liabilities on outstanding standby letters of credit agreements aggregated to zero at December 31, 2013 and 2012. The Company, as a U.S. Government contractor, is subject to audits, reviews, and investigations by the U.S. government related to its negotiation and performance of government contracts and its accounting for such contracts. Failure to comply with applicable U.S. Government standards by a contractor may result in suspension from eligibility for award of any new government contract and a guilty plea or conviction may result in debarment from eligibility for awards. The government may, in certain cases, also terminate existing contracts, recover damages, and impose other sanctions and penalties. As a result of a pending U.S. government audit the Company had determined a range of possible outcomes none of which the Company believes would have a materially adverse effect on the Company's financial position or results of operations.  In accordance with ASC 450 “Contingencies” the Company has accrued the amount within the range that appears to be its best estimate of a possible outcome.

Note 5. Recently Issued Accounting Standards

In February 2013, the FASB amended Accounting Standards No. 2013-02, “Comprehensive Income (Topic 220): Reporting of Amounts Reclassified Out of Accumulated Other Comprehensive Income,” to improve the transparency of reporting reclassifications out of accumulated other comprehensive income. Other comprehensive income includes gains and losses that are initially excluded from net income for an accounting period. Those gains and losses are later reclassified out of accumulated other comprehensive income into net income.

The amendments in the Update do not change the current requirements for reporting net income or other comprehensive income in financial statements. All of the information that this Update requires already is required to be disclosed elsewhere in the financial statements under U.S. Generally Accepted Accounting Principles.

The new amendments requires presentation of (either on the face of the statement where net income is presented or in the notes) the effects on the line items of net income of significant amounts reclassified out of accumulated other comprehensive income, but only if the item reclassified is required under U.S. GAAP to be reclassified to net income in its entirety in the same reporting period. Furthermore, the new amendments requires a cross-reference to other disclosures currently required under U.S. GAAP for other reclassification items (that are not required under U.S. GAAP) to be reclassified directly to net income in their entirety in the same reporting period. This would be the case when a portion of the amount reclassified out of accumulated other comprehensive income is initially transferred to a balance sheet account (e.g., inventory for pension-related amounts) instead of directly to income or expense. The amendments are effective for reporting periods beginning after December 15, 2012.  The adoption of this guidance did not have a material impact on the Company’s financial statements.

Employee Stock Ownership Plan

Note 6. Employee Stock Ownership Plan

The Company sponsors a leveraged employee stock ownership plan (the "ESOP") that covers all nonunion employees who work 1,000 or more hours per year and are employed on June 30. The Company makes annual contributions to the ESOP equal to the ESOP's debt service less dividends on unallocated shares received by the ESOP. All dividends on unallocated shares received by the ESOP are used to pay debt service. Dividends on allocated ESOP shares are recorded as a reduction of retained earnings. As the debt is repaid, shares are released and allocated to active employees, based on the proportion of debt service paid in the year. The Company accounts for its ESOP in accordance with FASB ASC 718-40. Accordingly, the shares purchased by the ESOP are reported as Unearned ESOP Shares in the statement of financial position. As shares are released or committed-to-be-released, the Company reports compensation expense equal to the current average market price of the shares, and the shares become outstanding for earnings-per-share (EPS) computations. ESOP compensation expense was $153,236 and $132,751 for the three-month periods ended December 31, 2013 and 2012, respectively. ESOP compensation expense was $283,663 and $272,453 for the six-month periods ended December 31, 2013 and 2012, respectively.

The ESOP shares as of December 31, 2013 and 2012 were as follows:

 

    December 31, 2013   December 31, 2012  
Allocated Shares     469,338       453,091

The shares that, although not legally released, will be released by a future scheduled and committed debt service payment and will be allocated to employees for service rendered in the current accounting period. The ESOP documents typically define the period of service to which the shares relate. ESOP shares are released to compensate employees directly, to settle employer liabilities for other employee benefits, and to replace dividends on allocated shares that are used for debt service.  
Unreleased shares 107,083 126,666
