Basis of Presentation and Summary of Significant Accounting Policies and Recent Pronouncements [Abstract]
Basis of Presentation	Note 1—Basis of Presentation
	The accompanying unaudited consolidated financial statements of Straight Path Communications Inc. and its subsidiaries (“Straight Path”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information and with the instructions to Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments (consisting of normal recurring accruals) considered necessary for a fair presentation have been included. Operating results for the nine months ended April 30, 2015 are not necessarily indicative of the results that may be expected for the fiscal year ending July 31, 2015. The balance sheet at July 31, 2014 has been derived from Straight Path’s audited financial statements at that date but does not include all of the information and footnotes required by U.S. GAAP for complete financial statements. For further information, please refer to the combined and consolidated financial statements and footnotes thereto included in Straight Path’s Annual Report on Form 10-K for the fiscal year ended July 31, 2014, as filed with the U.S. Securities and Exchange Commission.
	Straight Path was incorporated in April 2013. Straight Path’s businesses consist of an indirect 100% ownership of Straight Path Spectrum, Inc. (“Straight Path Spectrum”), which holds, leases and markets fixed wireless spectrum licenses, and an indirect 84.5% ownership of Straight Path IP Group, Inc. (“Straight Path IP Group”), which holds intellectual property primarily related to communications over the Internet, and the licensing and other businesses related to this intellectual property. In these financial statements “the Company” refers to Straight Path, Straight Path Spectrum and Straight Path IP Group on a consolidated basis. All material intercompany balances and transactions have been eliminated in consolidation.
	The Company was formerly a subsidiary of IDT Corporation (“IDT”). On July 31, 2013, the Company was spun-off by IDT to its stockholders and became an independent public company (the “Spin-Off”). The Company authorized the issuance of two classes of its common stock, Class A (“Class A common stock”) and Class B (“Class B common stock”). The Spin-Off of the Company occurred by way of a pro rata distribution of the Company’s Class A common stock and Class B common stock held by IDT to IDT’s stockholders. On the distribution date, each IDT stockholder received one share of the Company’s Class A common stock for every two shares of IDT Class A common stock and one share of the Company’s Class B common stock for every two shares of IDT Class B common stock held on the record date for the Spin-Off. On July 31, 2013, the Company distributed approximately 787,000 shares of its Class A common stock that were outstanding on the record date and 10.7 million shares of its Class B common stock (based on 21.4 million shares of IDT Class B common stock that were outstanding on the record date).
	The Company’s fiscal year ends on July 31 of each calendar year. Each reference below to a fiscal year refers to the fiscal year ending in the calendar year indicated (e.g., fiscal 2015 refers to the fiscal year ending July 31, 2015).

Basis of Presentation and Summary of Significant Accounting Policies and Recent Pronouncements [Abstract]
Summary of Significant Accounting Policies and Recent Pronouncements	Note 2—Summary of Significant Accounting Policies and Recent Pronouncements
	The Company’s significant accounting policies are described in Note 1 of the Notes to Combined and Consolidated Financial Statements in the Annual Report on Form 10-K for the year ended July 31, 2014.
	In May 2014, ASU No. 2014-09, “Revenue from Contracts with Customers” was issued. The comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services. The guidance will also require that certain contract costs incurred to obtain or fulfill a contract, such as sales commissions, be capitalized as an asset and amortized as revenue is recognized. Adoption of the new rules could affect the timing of both revenue recognition and the incurrence of contract costs for certain transactions. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. As the Company qualifies as an emerging growth company, the new standard is effective for annual reporting periods beginning after December 15, 2017. Early adoption is permitted under certain circumstances. The Company is currently evaluating the impact of adoption and the implementation approach to be used.
	In June 2014, ASU 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period” (“ASU No. 2014-12”) was issued.  ASU No. 2014-12 requires that a performance target that affects vesting and that could be achieved after the requisite service period is treated as a performance condition. An entity should recognize compensation cost in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. ASU 2014-12 becomes effective for interim and annual periods beginning on or after December 15, 2015. Early adoption is permitted.  The Company is currently evaluating the effects of adopting ASU 2014-12 on its consolidated financial statements but the adoption is not expected to have a significant impact on the Company’s consolidated financial statements.
	In June 2014, ASU 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU No. 2014-15”) was issued.  Before the issuance of ASU 2014-15, there was no guidance in U.S. GAAP about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern or to provide related footnote disclosures. This guidance is expected to reduce the diversity in the timing and content of footnote disclosures. ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards as specified in the guidance. ASU 2014-15 becomes effective for the annual period ending after December 15, 2016 and for annual and interim periods thereafter. Early adoption is permitted. The Company is currently evaluating the effects of adopting ASU 2014-15 on its consolidated financial statements but the adoption is not expected to have a significant impact on the Company’s consolidated financial statements.
	In January 2015, the FASB issued ASU 2015-01, “Income Statement – Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items” (“ASU 2015-01”). ASU 2015-01 eliminates from GAAP the concept of extraordinary items. ASU 2015-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company anticipates that the adoption of ASU 2015-01 will not have a significant impact on the Company’s consolidated financial statements.
	In February 2015, the FASB issued ASU NO. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis” (“ASU 2015-02”). The amendments in ASU 2015-02 change the analysis that reporting entity must perform to determine whether it should consolidate certain types of legal entities. The amendments in ASU 2015-02 are effective for public business entities for fiscal years beginning after December 15, 2015. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. A reporting entity may apply the amendments in ASU 2015-02 using a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption. A reporting entity also may apply the amendments retrospectively. The adoption of ASU 2015-02 is not expected to have a material impact on the Company’s consolidated financial statements.
	Management does not believe that any other recently issued, but not yet effective, accounting standard if currently adopted would have a material effect on the accompanying financial statements.

	In October 2013, the Board of Directors approved an amendment to the Plan increasing the number of shares of the Company’s Class B common stock available for grant of awards by an additional 350,000 shares. The increase was approved by the stockholders on January 12, 2015 at the Company’s annual stockholder meeting.
	Stock-Based Compensation:
	From time to time, the Company issues Class B common stock and options to purchase Class B common stock to non-employee directors, officers, employees and other service providers. Stock-based compensation is included in selling, general and administrative expense and amounted to $294,794 and $130,375 for the three months ended April 30, 2015 and 2014, respectively, and $1,524,017 and $628,057 for the nine months ended April 30, 2015 and 2014, respectively. Issuances of Class B common stock included in stock-based compensation for the nine months ended April 30, 2015 are as follows:
	On August 1, 2014, the Company granted Davidi Jonas, its Chief Executive Officer, 71,000 restricted shares of Class B common stock and Jonathan Rand, its Chief Financial Officer, 52,000 restricted shares of Class B common stock. One-third of both grants of restricted shares vested on March 30, 2015 and the remaining vest as to approximately one-third of the granted shares on each of February 1, 2016 and 2017. The aggregate fair value of the grant was approximately $1,214,000 which is being charged to expense on a straight-line basis over the vesting period.
	On September 1, 2014, the Company granted Zhouyue (Jerry) Pi, its Chief Technology Officer, 60,000 restricted shares of Class B common stock.

These grants are the annual grants to non-employee directors provided for in the Plan. The shares vested immediately. The aggregate fair value of the grant was approximately $438,000.

Earnings (Loss) Per Share	9 Months Ended

Earnings (Loss) Per Share [Abstract]
Earnings (Loss) Per Share	Note 4—Earnings (Loss) Per Share
	Basic earnings (loss) per share is computed by dividing net income (loss) attributable to all classes of common stockholders of the Company by the weighted average number of shares of all classes of common stock outstanding during the applicable period. Diluted earnings per share is computed in the same manner as basic earnings per share, except that the number of shares is increased to include restricted stock still subject to risk of forfeiture and to assume exercise of potentially dilutive stock options using the treasury stock method, unless the effect of such increase would be anti-dilutive. The following table summarizes the components of the earnings (loss) per common share calculation:
		Three Months Ended				Nine Months Ended
		April 30,				April 30,
		2015		2014		2015		2014
		(in thousands)
	Basic weighted-average number of shares		11,449		11,339		11,426		10,878
	Effect of dilutive securities:
	Shares underlying stock options		5		7		6		—
	Non-vested restricted Class B common stock		425		303		405		—
	Diluted weighted-average number of shares		11,879		11,649		11,837		10,878
	The following shares were excluded from the diluted earnings (loss) per share computations because their inclusion would have been anti-dilutive:
		Three Months Ended				Nine Months Ended
		April 30,				April 30,
		2015		2014		2015		2014
		(in thousands)
	Stock options		—		—		—		30
	Non-vested restricted Class B common stock		—		—		—		474
	Shares excluded from the calculation of diluted earnings (loss) per share		—		—		—		504
	For the nine months ended April 30, 2014, the diluted loss per share equals basic loss per share because the Company had a net loss and the impact of the assumed exercise of stock options and assumed vesting of restricted stock would have been anti-dilutive.

Related Party Transactions [Abstract]
Related Party Transactions	Note 5—Related Party Transactions
	In connection with the Spin-Off, the Company and IDT entered into a Separation and Distribution Agreement and a Tax Separation Agreement to complete the separation of the Company’s businesses from IDT, to distribute the Company’s common stock to IDT’s stockholders and set forth certain understandings related to the Spin-Off. These agreements govern the relationship between the Company and IDT after the distribution and also provide for the allocation of employee benefits, taxes and other liabilities and obligations attributable to periods prior to the distribution. These agreements reflect terms between affiliated parties established without arms-length negotiation. The Company believes that the terms of these agreements equitably reflect the benefits and costs of the Company’s ongoing relationships with IDT.
	Pursuant to the Separation and Distribution Agreement, the Company has indemnified IDT and IDT has indemnified the Company for losses related to the failure of the other to pay, perform or otherwise discharge, any of the liabilities and obligations set forth in the agreement. The Separation and Distribution Agreement includes, among other things, that IDT is obligated to reimburse the Company for the payment of any liabilities of the Company arising or related to the period prior to the Spin-Off. In the three and nine months ended April 30, 2014, IDT paid approximately $332,000 and $383,000, respectively, pursuant to this obligation, which was recorded as “Income from IDT Corporation payments of liabilities” in the consolidated statement of operations. No payments were received in fiscal 2015.
	At the Spin-Off, the Company entered into a Transition Services Agreement (“TSA”) with IDT, pursuant to which IDT has provided certain services, including, but not limited to information and technology, human resources, payroll, tax, accounts payable, purchasing, treasury, financial systems, investor relations, legal, corporate accounting, internal audit, and facilities for an agreed period following the Spin-Off. As of January 1, 2015, all of these services are being provided by other vendors. The Company and IDT have extended the TSA until July 31, 2015 enabling the Company to seek input from IDT on an ad hoc basis if the Company deems necessary.
	IDT charged the Company for certain transactions and allocates routine expenses based on specific items prior to January 1, 2015. Specifically, IDT allocated payroll, benefits, insurance, facilities and other expenses to the Company, which were included in “Selling, general and administrative expense” in the consolidated statements of operations. In addition, IDT charged the Company for regulatory fees, connectivity charges and legal expenses, which were included in “Direct cost of revenues” in the consolidated statements of operations.
	Following are the amounts that IDT charged the Company pursuant to the TSA or through intercompany charges for periods prior to the Spin-Off:
		Three Months Ended				Nine Months Ended

Income Taxes [Abstract]
Income Taxes	Note 7—Income Taxes
	Because of the way it is structured, Straight Path and its subsidiaries file the following income tax returns.
	Straight Path Spectrum files its own tax returns. There is no provision for Straight Path Spectrum for the nine months ended April 30, 2015 and 2014 as it incurred a taxable loss in both periods. In addition, there is a 100% valuation allowance against the net operating losses generated by Straight Path Spectrum at both April 30, 2015 and 2014.
	The operations of Straight Path IP Group are included in the consolidated tax return of Straight Path. There is no provision for Straight Path for the nine months ended April 30, 2015. In February 2015, capital contributions were made to a wholly-owned limited liability company which allowed Straight Path to utilize certain suspended losses. The Company estimates that such suspended losses made available by the capital contributions will fully offset taxable income generated by Straight Path IP Group for the fiscal year. The remaining suspended losses can only be utilized by Straight Path if additional capital contributions are made.
	The provision for income taxes for the nine months ended April 30, 2015 consists solely of certain state income taxes. The provision for income tax benefits for the three months ended April 30, 2015 consists primarily of the reversal of income taxes previously accrued during the first and second quarters for the year ended April 30, 2015 as a result of the use of the suspended losses discussed above.
	The provision for income taxes for the nine and three months ended April 30, 2014 represents the estimated accrual for Straight Path.

Business Segment Information [Abstract]
Business Segment Information	Note 8—Business Segment Information
	The Company has two reportable business segments, Straight Path Spectrum, which holds, leases and markets fixed wireless spectrum, and Straight Path IP, which holds intellectual property primarily related to communications over computer networks, and the licensing and other businesses related to this intellectual property.
	The Company’s reportable segments are distinguished by types of service, customers and methods used to provide their services. The operating results of these business segments are regularly reviewed by the Company’s chief operating decision maker.
	The accounting policies of the segments are the same as the accounting policies of the Company as a whole. The Company evaluates the performance of its business segments based primarily on income (loss) from operations. There are no significant asymmetrical allocations to segments.
	Operating results for the business segments of the Company were as follows:

	Legal Proceedings
	Sipnet Appeal
	On April 11, 2013, Sipnet EU S.R.O., a Czech company, (“Petitioner”) filed a petition for an inter partes review (“IPR”) at the Patent Trial and Appeals Board of the United States Patent and Trademark Office (the “PTAB”) for certain claims of U.S. Patent 6,108,704 (the “’704 Patent”). On October 9, 2014, the PTAB issued an administrative decision that claims 1-7 and 32-42 of the ’704 Patent are unpatentable. We disagree with this finding, and on November 10, 2014, Straight Path IP Group filed a Notice of Appeal at the United States Court of Appeals for the Federal Circuit and at the PTAB (“Sipnet Appeal”). Straight Path IP Group’s opening appellate brief at the Federal Circuit Court of Appeals was filed on March 13, 2015. The parties’ briefing is now complete, and we expect a ruling from the appellate court in the next six to ten months.
	The decision of the PTAB has had a materially adverse impact on our enforcement efforts. During the pendency of the Sipnet Appeal and outstanding IPRs, all litigation related to the relevant patents that was brought by us as plaintiff has been stayed or dismissed without prejudice, and therefore, we are not currently moving forward with actions against Samsung Electronics Company et al (“Samsung”), LG Electronics, Inc. et al (“LG”), Toshiba Corporation et al (“Toshiba”), Vizio, Inc. (“Vizio”), Apple Inc. (“Apple”), Avaya Inc. (“Avaya”), Cisco Systems, Inc. (“Cisco”), or Verizon Communications, Inc. (“Verizon”). While most of the claims found to be unpatentable were not asserted in our enforcement actions, we intend to vigorously defend all of the claims of the ’704 Patent. The PTAB’s decision could lead to challenges to other claims of our patents, particularly if the decision withstands appeal.
	Additional Inter Partes Review
	On August 22, 2014, Samsung filed three petitions with the PTAB for IPR of certain claims of U.S. Patent Nos. 6,108,704, 6,009,469, and 6,131,121. Straight Path IP Group filed the Patent Owner’s Preliminary Statement in each of these proceedings on December 9, 2014. On March 6, 2015, the PTAB instituted the requested IPR of these claims based on Samsung’s petitions, citing certain findings in the Sipnet decision. Cisco, Avaya, and LG, Toshiba, and Vizio have requested to join the instituted Samsung IPRs using joinder provisions provided under PTAB rules, by filing petitions identical to the Samsung petitions, but the PTAB has not ruled on that request. LG, Toshiba, and Vizio have since notified the PTAB that they intend to withdraw their motions to join. On June 8, 2015, Straight Path IP Group filed its Patent Owner’s Response to the institution.
	On October 31, 2014, LG, Toshiba, Vizio and Hulu filed three petitions with the PTAB for IPR of certain claims of U.S. Patent Nos. 6,108,704, 6,009,469, and 6,131,121. Straight Path IP Group filed the Patent Owner’s Preliminary Statements for U.S. Patent No. 6,131,121 on February 18, 2015 and U.S. Patent Nos. 6,108,704 and 6,009,469 on February 20, 2015. On May 15, 2015, the PTAB instituted the requested IPR of these claims based on these petitions, citing certain findings in the Sipnet decision.
	Patent Enforcement
	On August 1, 2013, Straight Path IP Group filed complaints in the United States District Court for the Eastern District of Virginia against LG Electronics, Inc., LG Electronics U.S.A., Inc., and LG Electronics Mobilecomm U.S.A., Inc. (collectively “LG”), Toshiba Corporation, Toshiba America Inc., Toshiba America Information Systems, Inc. (collectively “Toshiba”) and Vizio, Inc., alleging infringement of three of its patents (U.S. Patent Nos. 6,108,704, 6,009,469, and 6,131,121), and seeking damages related to such infringement. The actions against LG, Toshiba, and Vizio have been consolidated (“consolidated action”). In October 2014, Hulu, LLC intervened in the action as to Hulu’s streaming functionality in the accused products. In that same month, Amazon.com, Inc. (“Amazon”) moved to intervene, sever, and stay claims related to Amazon’s streaming functionality in the accused products. On October 13, 2014, Amazon filed an action seeking declaratory relief of non-infringement of Straight Path IP Group’s U.S. Patent Nos. 6,009,469, 6,108,704, and 6,131,121 in the U.S. District Court for the Northern District of California based in part on the allegations related to the actions in Virginia. On December 5, 2014, Straight Path IP Group filed a motion to dismiss Amazon’s complaint, or in the alternative, to transfer venue to Virginia. On May 28, 2015, the California court transferred the matter to Virginia, where we expect that it will be consolidated and stayed with the other actions. In November 2014, Straight Path IP Group, defendants, and Hulu jointly moved to stay the consolidated action pending the completion of the defendants’ and Hulu’s IPR petitions of the asserted patents and the completion of the Sipnet Appeal. On November 4, 2014, the court granted the parties’ request and also held the briefing in the Amazon intervention in abeyance.
	On August 23, 2013, Straight Path IP Group filed a complaint in the United States District Court for the Eastern District of Texas against Samsung Electronics Co., Ltd., Samsung Electronics America, Inc. and Samsung Telecommunications America, LLC (collectively “Samsung”) alleging infringement of three of its patents (U.S. Patent Nos. 6,108,704, 6,009,469, and 6,131,121) and seeking damages related to such infringement. In September 2014, Straight Path IP Group and Samsung jointly filed a motion to stay the action. On October 29, 2014, the court granted the motion and stayed the action pending the outcome of the Sipnet Appeal and the IPR petitions filed by Samsung.
	On September 24, 2014, Straight Path IP Group filed complaints against each of Apple, Inc. (“Apple”), Avaya Inc. (“Avaya”), and Cisco Systems, Inc. (“Cisco”) in the United States District Court for the Northern District of California. Straight Path IP Group claims that (a) Apple’s telecommunications products, including FaceTime software, infringe four of its patents (U.S. Patent Nos. 6,108,704, 6,131,121, 6,701,365, and 7,149,208); that (b) Avaya’s IP telephony, video conference and telepresence products such as Defendant’s Aura Platform infringe four of its patents (U.S. Patent Nos. 6,009,469, 6,108,704, 6,131,121, and 6,701,365); and (c) Cisco’s IP telephony, video conference and telepresence products such as the Unified Communications Solutions infringe four of its patents (U.S. Patent Nos. 6,009,469, 6,108,704, 6,131,121, and 6,701,365). On December 24, 2014, Straight Path IP Group dismissed the complaints against Avaya and Cisco without prejudice. On January 5, 2015, Straight Path IP Group dismissed the complaint against Apple without prejudice.
	On September 26, 2014, Straight Path IP Group filed a complaint against Verizon Communications Inc., Verizon Services Corp., and Verizon Business Network Services Inc. (collectively “Verizon”) in the United States District Court for the Southern District of New York. Straight Path IP Group claims Verizon’s telephony products such as its Advanced Communications Products, including Unified Communications and Collaboration and VOIP infringe three of its patents (U.S. Patent Nos. 6,108,704, 6,131,121, and 6,701,365). On November 24, 2014, Straight Path IP Group dismissed the complaint without prejudice subject to a confidential Standstill Agreement with Verizon.
	Arbitration with the Former SPIP CEO
	On December 11, 2012, Straight Path IP Group filed a demand for arbitration seeking a declaration that the former Chief Executive Officer of Straight Path IP (the “Former SPIP CEO”) employment was properly terminated for cause and that the Former SPIP CEO is not entitled to severance or certain equity rights under his employment agreement. On March 15, 2013, the Former SPIP CEO filed a response and counterclaims alleging breach of contract and seeking various forms of relief. Specifically, he sought certain declarations related to the termination of his employment, and certain payments and the vesting of options to purchase common stock representing 5% of the outstanding common stock of Straight Path IP Group, damages for unpaid compensation and severance, a sum in excess of $35 million in compensatory damages, and punitive damages in an unspecified amount. The arbitration was held in November 2014. On February 26, 2015, the Arbitrator issued his Final Award. The Arbitrator concluded that the Former SPIP CEO is not entitled to any further compensation and does not have any entitlement to equity interests in Straight Path IP Group. On May 27, 2015, the Former SPIP CEO filed a petition in the Supreme Court of the State of New York, County of New York to vacate the arbitration award. We intend to oppose the petition.
	Other Commitments and Contingencies
	The former Chief Executive Officer of Straight Path Spectrum (the “Former SPSI CEO”) is entitled to receive payments from future revenues generated from the leasing, licensing or sale of rights in certain of Straight Path Spectrum’s wireless spectrum licenses. Those payments are to be made out of 50% of the covered revenue and are in a maximum aggregate amount of $3.25 million. The payments arise under the June 2013 settlement of certain claims and disputes with the Former SPSI CEO and parties related to the Former SPSI CEO. Approximately $3,000 and $44,000 was incurred to the Former SPSI CEO for this obligation for the three and nine months ended April 30, 2015, respectively, and approximately $33,000 and $87,000 for the three and nine months ended April 30, 2014, respectively.
	Straight Path IP Group generally pays law firms that represent it in litigation against alleged infringers of its intellectual property rights a percentage of the amounts recovered ranging from 0% to 40% depending on several factors.
	In March 2015, the Company extended the term of its Englewood Cliffs, New Jersey satellite office from October 31, 2017 to April 30, 2018. The annual rent will continue to be approximately $37,000 per year. In May 2015, the Company extended the lease for its headquarters in Glen Allen, Virginia from May 31, 2015 to May 31, 2017. The annual rent will be approximately $7,000 per year.

Basis of Presentation and Summary of Significant Accounting Policies and Recent Pronouncements [Abstract]
Summary of Significant Accounting Policies and Recent Pronouncements	The Company’s significant accounting policies are described in Note 1 of the Notes to Combined and Consolidated Financial Statements in the Annual Report on Form 10-K for the year ended July 31, 2014.
	In May 2014, ASU No. 2014-09, “Revenue from Contracts with Customers” was issued. The comprehensive new standard will supersede existing revenue recognition guidance and require revenue to be recognized when promised goods or services are transferred to customers in amounts that reflect the consideration to which the Company expects to be entitled in exchange for those goods or services. The guidance will also require that certain contract costs incurred to obtain or fulfill a contract, such as sales commissions, be capitalized as an asset and amortized as revenue is recognized. Adoption of the new rules could affect the timing of both revenue recognition and the incurrence of contract costs for certain transactions. The guidance permits two implementation approaches, one requiring retrospective application of the new standard with restatement of prior years and one requiring prospective application of the new standard with disclosure of results under old standards. As the Company qualifies as an emerging growth company, the new standard is effective for annual reporting periods beginning after December 15, 2017. Early adoption is permitted under certain circumstances. The Company is currently evaluating the impact of adoption and the implementation approach to be used.
	In June 2014, ASU 2014-12, “Accounting for Share-Based Payments When the Terms of an Award Provide That a Performance Target Could Be Achieved after the Requisite Service Period” (“ASU No. 2014-12”) was issued.  ASU No. 2014-12 requires that a performance target that affects vesting and that could be achieved after the requisite service period is treated as a performance condition. An entity should recognize compensation cost in the period in which it becomes probable that the performance target will be achieved and should represent the compensation cost attributable to the periods for which the requisite service has already been rendered. If the performance target becomes probable of being achieved before the end of the requisite service period, the remaining unrecognized compensation cost should be recognized prospectively over the remaining requisite service period. The total amount of compensation cost recognized during and after the requisite service period should reflect the number of awards that are expected to vest and should be adjusted to reflect those awards that ultimately vest. ASU 2014-12 becomes effective for interim and annual periods beginning on or after December 15, 2015. Early adoption is permitted.  The Company is currently evaluating the effects of adopting ASU 2014-12 on its consolidated financial statements but the adoption is not expected to have a significant impact on the Company’s consolidated financial statements.
	In June 2014, ASU 2014-15, “Presentation of Financial Statements – Going Concern (Subtopic 205-40): Disclosure of Uncertainties about an Entity’s Ability to Continue as a Going Concern” (“ASU No. 2014-15”) was issued.  Before the issuance of ASU 2014-15, there was no guidance in U.S. GAAP about management’s responsibility to evaluate whether there is substantial doubt about an entity’s ability to continue as a going concern or to provide related footnote disclosures. This guidance is expected to reduce the diversity in the timing and content of footnote disclosures. ASU 2014-15 requires management to assess an entity’s ability to continue as a going concern by incorporating and expanding upon certain principles that are currently in U.S. auditing standards as specified in the guidance. ASU 2014-15 becomes effective for the annual period ending after December 15, 2016 and for annual and interim periods thereafter. Early adoption is permitted. The Company is currently evaluating the effects of adopting ASU 2014-15 on its consolidated financial statements but the adoption is not expected to have a significant impact on the Company’s consolidated financial statements.
	In January 2015, the FASB issued ASU 2015-01, “Income Statement – Extraordinary and Unusual Items (Subtopic 225-20): Simplifying Income Statement Presentation by Eliminating the Concept of Extraordinary Items” (“ASU 2015-01”). ASU 2015-01 eliminates from GAAP the concept of extraordinary items. ASU 2015-01 is effective for fiscal years, and interim periods within those fiscal years, beginning after December 15, 2015. A reporting entity may apply the amendments prospectively. A reporting entity also may apply the amendments retrospectively to all prior periods presented in the financial statements. Early adoption is permitted provided that the guidance is applied from the beginning of the fiscal year of adoption. The Company anticipates that the adoption of ASU 2015-01 will not have a significant impact on the Company’s consolidated financial statements.
	In February 2015, the FASB issued ASU NO. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis” (“ASU 2015-02”). The amendments in ASU 2015-02 change the analysis that reporting entity must perform to determine whether it should consolidate certain types of legal entities. The amendments in ASU 2015-02 are effective for public business entities for fiscal years beginning after December 15, 2015. If an entity early adopts the amendments in an interim period, any adjustments should be reflected as of the beginning of the fiscal year that includes that interim period. A reporting entity may apply the amendments in ASU 2015-02 using a modified retrospective approach by recording a cumulative-effect adjustment to equity as of the beginning of the fiscal year of adoption. A reporting entity also may apply the amendments retrospectively. The adoption of ASU 2015-02 is not expected to have a material impact on the Company’s consolidated financial statements.
	Management does not believe that any other recently issued, but not yet effective, accounting standard if currently adopted would have a material effect on the accompanying financial statements.
