Note 1. Basis of Presentation

In the opinion of management the accompanyingunaudited financial statements contain all adjustments (consisting of only normal recurring adjustments) necessary for a fair presentationof the results for such periods. The results for any interim period are not necessarily indicative of the results to be expectedfor the full fiscal year. Certain information and footnote disclosures normally included in financial statements prepared in accordancewith United States generally accepted accounting principles have been condensed or omitted. The preparation of these financialstatements 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 thoserelated to revenue recognition, inventories, income taxes, and stock-based compensation. Management bases its estimates on historicalexperience and on various other factors that are believed to be reasonable under the circumstances, the results of which form thebasis 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 beread in conjunction with the Company's most recent audited financial statements included in its report on Form 10-K for the yearended June 30, 2013. Certain reclassifications may have been made to the prior year financial statements to conform to the currentyear presentation.

Net Income per Share

Note 2. Net Income per Share

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

Stock Based Compensation

Note 3. Stock Based Compensation

TheCompany follows ASC 718 in establishing standards for the accounting for transactions in which an entity exchanges its equity instrumentsfor goods or services, as well as transactions in which an entity incurs liabilities in exchange for goods or services that arebased 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 basedon the fair value of the share-based payment. ASC 718 establishes fair value as the measurement objective in accounting for share-basedpayment transactions with employees, except for equity instruments held by employee share ownership plans.

Total stock-based compensation expenserecognized in the Statements of Comprehensive Income for the three-month period ended March 31, 2014 and 2013, was $25,478 and$27,406, respectively, before income taxes. The related total deferred tax benefit was approximately $2,774 and $3,116 for thethree-month period ended March 31, 2014 and 2013, respectively. Total stock-based compensation expense recognized in the Statementsof Comprehensive Income for the nine-month period ended March 31, 2014 and 2013, was $77,721 and $87,777, respectively, beforeincome taxes. The related total deferred tax benefit was approximately $8,553 and $9,852 for the nine-month period ended March31, 2014 and 2013, respectively. ASC 718 requires the tax benefits resulting from tax deductions in excess of the compensationcost recognized for those options to be classified and reported as both an operating cash outflow and a financing cash inflow.

As of March 31, 2014, there was approximately$82,130 of unrecognized compensation cost related to stock option awards that is expected to be recognized as expense over thenext 1.5 years. The total deferred tax benefit related to these awards is approximately $8,703.

The Company has one employee stock optionplan under which options may be granted, the 2007 Stock Option and Restricted Stock Plan (the "2007 Plan"). The Boardof Directors may grant options to acquire shares of common stock to employees of the Company at the fair market value of the commonstock on the date of grant. Generally, options granted have a two-year vesting period based on two years of continuous serviceand have a ten-year contractual life. Option grants provide for accelerated vesting if there is a change in control. Shares issuedupon the exercise of options are from those held in Treasury. The 2007 Plan was approved by the Company's shareholders at the Company'sAnnual Meeting on November 30, 2007 and supersedes the Company's 2000 Stock Option Plan (the "2000 Plan"). Options covering400,000 shares were authorized for issuance under the 2007 Plan, of which 190,100 have been granted and 146,135 are outstandingas of March 31, 2014. While no further grants of options may be made under the 2000 Plan, as of March 31, 2014, 30,730 optionsremain outstanding, vested and exercisable from the 2000 Plan.

ASC 718 requires the use of a valuationmodel 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 weightedaverage assumptions that the Company used to calculate the fair value of each option award for the nine-months ended March 31,2014. There were no options awarded for the nine-months ended March 31, 2013.

   March 31, 2014 
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 quarterlyand has paid a special cash dividend of $1.00 per share in each of fiscal years 2014 and 2013. Our Board of Directors assessesthe Company’s dividend policy periodically. There is no assurance that the Board of Directors will either maintain the amountof the regular cash dividend or declare a special dividend during any future years. Expected stock price volatility is based onthe historical volatility of the Company’s stock. The risk-free interest rate is based on the implied yield available onU.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 stockoption activity during the nine-months ended March 31, 2014:

   Employee Stock Options Plan
         Weighted  
   Number of Weighted Average  
   Shares Average Remaining Aggregate
   Subject Exercise Contractual Intrinsic

Outstanding at March 31, 2014   176,865   $22.35    6.28   $866,596 
Vested or expected to vest at March 31, 2014   168,951   $22.17    6.17   $858,303 
Exercisable at March 31, 2014   116,415   $20.33    4.97   $805,419 

 

The aggregate intrinsic value in thetable above represents the total pretax intrinsic value (the difference between the closing sale price of the company’s commonstock as reported on the NYSE MKT on March 31, 2014 and the exercise price, multiplied by the number of in-the-money options) thatwould have been received by the option holders if all option holders had exercised their options on March 31, 2014. This amountchanges based on the fair market value of the company’s common stock. The total intrinsic values of the options exercisedduring the nine-months ended March 31, 2014 and 2013 was $89,288 and $52,999, respectively.

Note 4. Commitments and Contingencies

The Company at certain times enters intostandby letters of credit agreements with financial institutions primarily relating to the guarantee of future performance on certaincontracts. Contingent liabilities on outstanding standby letters of credit agreements aggregated to zero at March 31, 2014 and2013. The Company, as a U.S. Government contractor, is subject to audits, reviews, and investigations by the U.S. government relatedto its negotiation and performance of government contracts and its accounting for such contracts. Failure to comply with applicableU.S. Government standards by a contractor may result in suspension from eligibility for award of any new government contract anda guilty plea or conviction may result in debarment from eligibility for awards. The government may, in certain cases, also terminateexisting contracts, recover damages, and impose other sanctions and penalties. As a result of a pending U.S. government audit theCompany has determined a range of possible outcomes none of which the Company believes would have a materially adverse effect onthe Company's financial position or results of operations.  In accordance with ASC 450 “Contingencies” the Companyhas accrued the amount within the range that appears to be its best estimate of a possible outcome.

Recently Issued Accounting Standards

Note 5. Recently Issued Accounting Standards

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

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

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

Employee Stock Ownership Plan

Note 6.Employee Stock Ownership Plan

The Company sponsorsa leveraged employee stock ownership plan (the "ESOP") that covers all nonunion employees who work 1,000 or more hoursper year and are employed on June 30. The Company makes annual contributions to the ESOP equal to the ESOP's debt service lessdividends on unallocated shares received by the ESOP. All dividends on unallocated shares received by the ESOP are used to paydebt service. Dividends on allocated ESOP shares are recorded as a reduction of retained earnings. As the debt is repaid, sharesare released and allocated to active employees, based on the proportion of debt service paid in the year. The Company accountsfor its ESOP in accordance with FASB ASC 718-40. Accordingly, the shares purchased by the ESOP are reported as Unearned ESOP Sharesin the statement of financial position. As shares are released or committed-to-be-released, the Company reports compensation expenseequal to the current average market price of the shares, and the shares become outstanding for earnings-per-share (EPS) computations.ESOP compensation expense was $144,323 and $129,101 for the three-month periods ended March 31, 2014 and 2013, respectively. ESOPcompensation expense was $427,987 and $401,554 for the nine-month periods ended March 31, 2014 and 2013, respectively.
