Statement Presentation And Basis Of Consolidation	'
	1. STATEMENT PRESENTATION AND BASIS OF CONSOLIDATION
	The accompanying unaudited condensed financial statements are presented on a consolidated basis. The accompanying financial statements include the accounts of National American University Holdings, Inc. (the “Company”), its subsidiary, Dlorah, Inc. (“Dlorah”), and its divisions, National American University (“NAU” or the “University”), and Fairway Hills. The accompanying unaudited condensed consolidated financial statements have been prepared on a basis substantially consistent with the Company’s audited financial statements and in accordance with the requirements of the Securities and Exchange Commission (“SEC”) for interim financial reporting. As permitted under these rules, certain footnotes and other financial information that are normally required by accounting principles generally accepted in the United States (“U.S. GAAP”) can be condensed or omitted. The information in the condensed balance sheet as of May 31, 2013, was derived from the audited financial statements for the Company for the year then ended. Accordingly, these financial statements should be read in conjunction with the Company’s annual financial statements which were included in the Company’s 10-K filed on August 2, 2013. Furthermore, the results of operations and cash flows for the six month periods ended November 30, 2013 and 2012 are not necessarily indicative of the results that may be expected for the full year. These financial statements include consideration of subsequent events through issuance. All intercompany transactions and balances have been eliminated.
	In the opinion of management, the accompanying condensed consolidated financial statements contain all adjustments necessary for a fair presentation as prescribed by U.S. GAAP.
	Unless the context otherwise requires, the terms “we”, “us”, “our” and the “Company” used throughout this document refer to National American University Holdings, Inc. and its wholly owned subsidiary, Dlorah, Inc., which owns and operates National American University, sometimes referred to as “NAU” or the “University”.
	Estimates — The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts and disclosures reported in the financial statements. On an ongoing basis, the Company evaluates the estimates and assumptions, including those related to bad debts, income taxes and certain accruals. Actual results could differ from those estimates.

	2. NATURE OF OPERATIONS
	The Company’s common stock is listed as NAUH on The NASDAQ Global Market. The Company, through Dlorah, owns and operates National American University. NAU is a regionally accredited, proprietary, multi-campus institution of higher learning, offering associate, bachelors, master’s and doctoral degree programs in business-related disciplines, such as accounting, applied management, business administration and information technology, and in healthcare-related disciplines, such as nursing and healthcare management. In addition, in August 2013, NAU was approved by the Higher Learning Commission to offer an Education Doctorate (Ed.D) in Community College Leadership, which will be offered in Austin, Texas. Courses are offered through educational sites and online. Operations include educational sites (two of which are pending regulatory approvals – Houston, Texas and the Rouche Graduate Center in Austin, Texas) located in Colorado, Indiana, Kansas, Minnesota, Missouri, Nebraska, New Mexico, Oklahoma, Oregon, South Dakota and Texas; distance learning service centers in Indiana and Texas; and distance learning operations and central administration offices in Rapid City, South Dakota. A substantial portion of NAU’s academic income is dependent upon federal student financial aid programs, employer tuition assistance, and contracts to provide online course development, hosting and technical assistance to other educational institutions. To maintain eligibility for financial aid programs, NAU must comply with U.S. Department of Education requirements, including the maintenance of certain financial ratios.
	The Company, through Dlorah’s Fairway Hills real estate division, also manages apartment units and develops and sells multi-family residential real estate in the Rapid City, South Dakota area.
	For the six months ended November 30, 2013 and 2012 91%, of the Company’s total revenues were derived from NAU’s academic revenue.

	3. EARNINGS PER SHARE
	Basic earnings per share (“EPS”) is computed by dividing net income attributable to National American University Holdings, Inc. by the weighted average number of shares of common stock outstanding during the applicable period. Diluted earnings per share reflect the potential dilution that could occur assuming vesting, conversion or exercise of all dilutive unexercised options, warrants and restricted stock.
	The following is a reconciliation of the numerator and denominator for the basic and diluted EPS computations:

	A total of 370,750 shares of common stock subject to issuance upon exercise of stock options for the three and six months ended November 30, 2012, respectively, have been excluded from the calculation of diluted EPS as the effect would have been anti-dilutive.

Contract For Deed	'
	5. CONTRACT FOR DEED
	The Company signed a contract for deed on its former Rapid City campus located at 321 Kansas City Street on March 28, 2013 for $4,000. Of this sales price, $20 was received as a down payment. The remaining $3,980 is being financed by the Company for three years at 5% interest. Annual interest payments are due each December 31. No principal payments are required until the expiration of the contract’s three-year term; however, any such payments received may result in removal of the lien on certain buildings included in the campus property.
	Because the buyer’s initial and continuing investment is not adequate in accordance with ASC 360-20-40, and the note receivable is not supported by specific evidence of collectability, the sale has not met the accounting requirements to be considered consummated. As such, the property remains on the condensed consolidated balance sheets and continues to be depreciated because the asset has not met the held for sale criteria, the note receivable has not been recorded, and interest income will be recognized as received. The sale will be recorded at such time the uncertainties surrounding the transaction are removed. For federal income tax purposes, the sale has been recognized. A portion of the taxable gain will be due for the year ended May 31, 2013, and the remaining portion will be payable as cash is received under the installment method.
	As part of the contract for deed, the University is leasing back the Animal Health building for $7 per month under a long-term lease agreement beginning June 1, 2013. The building is not considered a significant portion of the property sold. All rent due to the buyer will offset interest income payments due under the contract for deed.
	On July 8, 2013, the Company received $760 as payment on the contract for deed, to include $10 in interest and $500 toward the release of a lien on the dormitory buildings included in the campus property. As such, the dormitory buildings and land were deemed sold, resulting in a gain of $97. The remaining cash received of $250 is considered a non-refundable deposit at November 30, 2013.

	6. STOCKHOLDERS’ EQUITY
	Stock-Based Compensation
	In December 2009, the Company adopted the 2009 Stock Option and Compensation Plan (the “Plan”) pursuant to which the Company may grant restricted stock awards, restricted stock units and stock options to aid in recruiting and retaining employees, officers, directors and other consultants. Restricted stock awards accrue dividends that are paid when the shares vest. Restricted stock unit awards do not accrue dividends prior to vesting. Grants are issued at prices determined by the compensation committee, generally equal to the closing price of the stock on the date of the grant, vest over various terms (generally three years), and expire ten years from the date of the grant. The Plan allows vesting based upon performance criteria. Certain option and share awards provide for accelerated vesting if there is a change in control of the Company (as defined in the Plan). The fair value of stock options granted is calculated using the Black-Scholes option pricing model. Share options issued under the Plan may be incentive stock options or nonqualified stock options. At November 30, 2013, all stock options issued have been nonqualified stock options. A total of 1,300,000 shares were authorized by the Plan. Shares forfeited or canceled are eligible for reissuance under the Plan. At November 30, 2013, 830,221 shares of common stock remain available for issuance under the Plan.
	In April 2013, the Company’s Board of Directors recommended shareholder approval, and approval was obtained at the October 2013 Shareholder Meeting, to establish the 2013 Restricted Stock Unit Plan (the “2013 Plan”) authorizing the issuance of up to 750,000 shares of the Company’s stock to participants in the 2013 Plan. The Company may grant restricted stock awards or restricted stock units to aid in recruiting and retaining employees, officers, directors and other consultants. Restricted stock awards accrue dividends that are paid when the shares vest. Restricted stock unit awards do not accrue dividends prior to vesting. Restricted stock grants are issued at prices determined by the compensation committee, generally equal to the closing price of the stock on the date of the grant and vest over various terms. Shares forfeited or canceled are eligible for reissuance under the Plan. At November 30, 2013, 88,000 shares of common stock remain available for issuance under the 2013 Plan.
	Restricted stock
	The fair value of restricted stock awards was calculated using the Company’s stock price as of the associated grant date, and the expense is accrued ratably over the vesting period of the award.
	During the quarter ended August 31, 2013, the Company issued 750,000 restricted stock units (“RSUs”) with performance based vesting under the 2013 Plan. Approval of the 2013 Plan was received at the October shareholder meeting. 446,500 RSU’s were issued at a grant date fair value of $3.78 per share. The remaining 303,500 RSUs were issued to certain holders of time based vesting stock options who surrendered a like number of stock options in exchange. The grant date fair value of these modified RSUs was $4.31 per share. This represents the total of the remaining unamortized fair value associated with the options surrendered, $420, plus the incremental fair value at the time of the exchange calculated using the restricted stock fair value, $3.78 per share, and the fair value of the stock options immediately prior to surrender. The incremental fair value was $890. The total fair value of these modified awards, $1,310, will be amortized over the two year service period of the RSUs. The number of shares to be earned will determined by the Company’s profitability during the year ending May 31, 2015 along with attaining certain operating metrics.
	During the quarter ended November 30, 2013 88,000 RSUs granted under the 2013 Plan were cancelled. No additional restricted shares were issued during the quarter ended November 30, 2013.
	Compensation expenses associated with restricted stock awards and restricted stock unit awards, respectively, totaled $20 and $288 for the quarter ended November 30, 2013; year to date compensation expense associated with restricted stock awards and restricted stock unit awards, respectively totaled $32 and $662 for the six month period ended November 30, 2013. For the quarter ended November 30, 2012, compensation expenses associated with restricted stock awards and restricted stock unit awards, respectively, totaled $12 and $60; year to date compensation expense associated with restricted stock awards and restricted stock unit awards, respectively totaled $18 and $77 for the six month period ended November 30, 2012. At November 30, 2013, unamortized compensation cost of restricted stock and restricted stock unit awards totaled $2,079. The unamortized cost is expected to be recognized over a weighted-average period of 1.5 years as of November 30, 2013.

	Stock options
	The Company accounts for stock option-based compensation by estimating the fair value of options granted using a Black-Scholes option valuation model. The Company recognizes the expense for grants of stock options on a straight-line basis in the statement of operations as operating expense based on their fair value over the requisite service period.
	There were no stock options issued in the quarter or year to date periods ended November 30, 2013. For stock options issued during the six months ended November 30, 2012, the following assumptions were used to determine fair value:

	Weighted average fair value	$2.01
	The volatilities are based on historic volatilities from the traded shares of the Company over the past two and one-half years. The Company has analyzed the forfeitures of stock and option grants and has deemed the effect to be immaterial and therefore did not include a forfeiture rate in the expense calculation. The expected term of options granted is the safe harbor period. The risk-free interest rate for periods matching the contractual life of the option is based on the U.S. Treasury yield curve in effect at the time of grant. Expected dividend is based on the historic dividend of the Company.

	Following is a summary of the valuation techniques for assets and liabilities recorded in the consolidated condensed balance sheets at fair value on a recurring basis:
	CD’s and money market accounts: Investments which have closing prices readily available from an active market are used as being representative of fair value. The Company classifies these investments as level 1. Market prices for certain CD’s are obtained from quoted prices for similar assets. The Company classifies these investments as level 2.
	U.S. treasury bills and notes: Closing prices are readily available from active markets and are used as being representative of fair value. The Company classifies these investments as level 1.
	Fair value of financial instruments: The Company’s financial instruments include cash and cash equivalents, CD’s and money market accounts, US treasury bills and notes, receivables, payables, and capital lease payables. The carrying values approximated fair values for cash and cash equivalents, receivables, and payables because of the short term nature of these instruments. CD’s and money market accounts, and treasury bills and notes are recorded at fair values as indicated in the preceding disclosures.

	During the quarter ended November 30, 2013, the Company increased its capital lease obligation by $2,000 to account for tenant improvements. The Company initially paid for the improvements; however, the lessor will reimburse the Company under the terms of a $2,000 note receivable. The note receivable requires monthly payments of $14 at 6.0%. Such payments will directly offset the monthly payments to the lessor under the capital lease obligation. Future minimum commitments under the revised capital lease obligation as of November 30, 2013 are as follows:

	Operating segments are defined as business areas or lines of an enterprise about which financial information is available and evaluated on a regular basis by the chief operating decision makers, or decision-making groups, in deciding how to allocate capital and other resources to such lines of business.
	The Company operates two operating and reportable segments: NAU and other. The NAU segment contains the revenues and expenses associated with the University operations and the allocated portion of corporate overhead. The other segment contains primarily real estate. These operating segments are divisions of the Company for which separate financial information is available and evaluated regularly by executive management in deciding how to allocate resources and in assessing performance.
	General administrative costs of the Company are allocated to specific divisions of the Company.
