Description of Business and Summary of Significant Accounting Policies [Abstract]
Description of Business and Summary of Significant Accounting Policies	Note 1—Description of Business and Summary of Significant Accounting Policies Description of Business Straight Path Communications Inc. (“Straight Path”), a Delaware corporation, was incorporated in April 2013. Straight Path owns 100% of Straight Path Spectrum, Inc. (“Straight Path Spectrum”) and Straight Path Ventures, LLC (“Straight Path Ventures”), and 84.5% of Straight Path IP Group, Inc. (“Straight Path IP Group”). In these financial statements, the “Company” refers to Straight Path, Straight Path Spectrum, Straight Path Ventures, and Straight Path IP Group on a consolidated basis. All material intercompany balances and transactions are eliminated in producing our consolidated financial statements. 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”). On May 11, 2017, the Company entered into a merger agreement with Verizon Communications, Inc. (“Verizon”) and a Verizon subsidiary. For a further discussion, see Note 2 – Verizon Merger Agreement On January 11, 2017, the Company entered into a consent decree with the Federal Communications Commission (the “FCC”) settling the FCC’s investigation regarding Straight Path Spectrum’s spectrum licenses (the “Consent Decree”). The Company agreed to pay an initial civil penalty of $15 million (the “Initial Civil Penalty”). For further discussion, see Note 11 – Regulatory Enforcement On March 7, 2017, the Company and lead plaintiff in Zacharia v. Straight Path Communications Inc. et al Shareholder Litigation On April 9, 2017, the Company and IDT entered into a binding term sheet (the “IDT Term Sheet”) to settle potential claims related to certain claims under agreements related to the Spin-Off, and to sell the Company’s interest in Straight Path IP Group to IDT. For further discussion, see Note 3 – Settlement of Claims with IDT and Sale of Straight Path IP Group 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 2017 refers to the fiscal year ending July 31, 2017). Straight Path Spectrum Straight Path Spectrum’s wholly-owned subsidiary, Straight Path Spectrum, LLC, holds a broad collection of exclusively licensed commercial fixed and mobile wireless spectrum licenses. These licenses, granted by the FCC, include 735 licenses in the 39 gigahertz (“GHz”) band and 133 licenses in the local multipoint distribution service (“LMDS”) band. Straight Path Spectrum offers its customers point-to-point and point-to-multipoint wireless broadband digital telecommunications services. The broad geographical reach of the licenses enables Straight Path Spectrum to provide its services throughout the United States. The Consent Decree with the FCC bars the Company from entering into any new leases of its spectrum, which will limit our ability to increase our leasing revenue in the future. In addition, under the merger agreement with Verizon, we are restricted from taking certain actions that would be inconsistent with the intent of the Verizon Merger Agreement as more fully described in that agreement. Accordingly, we currently are not seeking to expand our leasing or other spectrum business operations. For further discussion, see Note 11 – Regulatory Enforcement. In October 2010, Straight Path Spectrum paid an aggregate of $210,000 to renew certain of its 39 GHz spectrum licenses and established a new expiration date of October 18, 2020 for these licenses. The Company included the license renewal costs in other assets, which are being charged to expense on a straight-line basis over the ten-year term of the licenses. Straight Path Ventures Straight Path Ventures, a Delaware limited liability company, develops next generation wireless technology for 39 GHz at its Gigabit Mobility Lab in Plano, Texas. On August 22, 2016, Straight Path Ventures filed a provisional patent application with the United States Patent and Trademark Office (“USPTO”) for new 39 GHz transceiver technology. On October 12, 2016, Straight Path Ventures filed a patent application with the USPTO for new millimeter-wave transceiver technologies. On August 31, 2017, Straight Path Ventures demonstrated its prototype 39 GHz Gigarray ® Straight Path IP Group Straight Path IP Group is a Delaware corporation. The Company believes that many parties are operating by infringing on Straight Path IP Group’s intellectual property, specifically one or more of Straight Path IP Group’s patents related to communications over the Internet. The Company is enforcing its rights and seeking to license its patents in order to generate revenue. Straight Path IP Group’s patent portfolio consists of the NetSpeak and Droplet portfolios. The NetSpeak portfolio includes U.S. Patents Nos. 6,131,121; 6,701,365; 6,513,066; 6,185,184; 6,829,645; 6,687,738; 6,009,469; 6,226,678; 7,149,208 and 6,178,453, and the foreign counterparts to U.S. Patent No. 6,108,704, which are German Patent No. 852868 and Taiwan Patent No. NI-096566. The Droplet portfolio includes U.S. Patents Nos. 6,847,317; 7,844,122; 7,525,463; 8,279,098; 7,436,329; 7,679,649, 8,947,271, 8,896,717, 8,849,964, 8,896,652 and a number of U.S. and foreign patent applications. These patents had finite lives, and all of them have expired. Straight Path IP Group may continue to enforce the patents for patent infringement that occurred before expiration, although we do not anticipate filing additional actions. There is no guarantee that the patents will be adequately exploited or commercialized. We generally pay law firms that represent us in litigation against alleged infringers of our intellectual property rights a percentage of the amounts recovered ranging from 0% to 40% depending on several factors. In addition, beginning on October 2, 2017, Straight Path IP Group will pay one of the law firms $100,000 per month as a non-refundable fee creditable against any contingency payment that may be paid to that firm in the future; there are also other directly related legal expenses, such as expert testimony, travel, filing fees, and others. Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates. Revenue Recognition Straight Path Spectrum lease revenues are recognized on a straight-line basis over the contractual lease period, which generally range from one to five years. Revenues from sale of rights in FCC licenses are recognized upon execution of the agreement by both parties, provided that the amounts are fixed or determinable, there are no significant undelivered obligations and collectability is reasonably assured. Straight Path Spectrum recorded the amounts that the former Chief Executive Officer of Straight Path Spectrum (the “Former SPSI CEO”) was entitled to, related to leases, in “Selling, general and administrative” expense, in the same period the related revenues were recognized. Straight Path Ventures develops next generation wireless technology and has no revenue at this time. Straight Path IP Group licensed its portfolio of patents to companies who used these patents in the provision of their product(s) and/or service(s). The contractual terms of the license agreements entered into in prior periods generally provided for payments over an extended period of time. For the licensing agreements with fixed royalty payments, Straight Path IP Group generally recognized revenue on a straight-line basis over the contractual term of the license, once collectability of the amounts was reasonably assured. For the licensing agreements with variable royalty payments which are based on a percentage of sales, Straight Path IP Group earned royalties at the time that the customers’ sales occurred. Straight Path IP Group’s customers, however, did not report and pay royalties owed for sales in any given period until after the conclusion of that period. As Straight Path IP Group was unable to estimate the customers’ sales in any given period to determine the royalties due to Straight Path IP Group, it recognized royalty revenues when sales and royalties were reported by customers and when other revenue recognition criteria were met. In addition, Straight Path IP Group entered into certain settlements of patent infringement disputes. The amount of consideration received upon any settlement (including but not limited to past royalty payments and future royalty payments) was allocated to each element of the settlement based on the fair value of each element. In addition, revenues related to past royalties were recognized upon execution of the agreement by both parties, provided that the amounts were fixed or determinable, there were no significant undelivered obligations and collectability was reasonably assured. Straight Path IP Group did not recognize any revenues prior to execution of the agreement since there was no reliable basis on which it could estimate the amounts for royalties related to previous periods or assess collectability. Direct Cost of Revenues Direct cost of revenues for Straight Path Spectrum consists primarily of network and connectivity costs. Such costs are charged to expense as incurred. Direct cost of revenues for Straight Path IP Group consisted of legal expenses directly related to revenues from litigation settlements. Cash Equivalents and Concentrations of Credit Risk The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash equivalents consist of money market accounts. The Company maintains principally all cash and cash equivalent balances in various financial institutions, which at times may exceed the amounts insured by the Federal Deposit Insurance Corporation. The exposure to the Company is solely dependent upon daily bank balances and the respective strength of the financial institutions. The Company has not incurred any losses on these accounts. Inventory Inventory, consisting solely of finished goods, is valued at the lower of cost or market determined on the first-in, first-out (FIFO) basis. The Company periodically evaluates inventory items and establishes reserves for obsolescence accordingly. The Company also reserves for excess quantities, slow-moving goods, and for other impairment of value based upon assumptions of future demand and market conditions. No reserve for obsolescence was recorded as of July 31, 2017. Intangible Assets Intangible assets consist primarily of the cost of the wireless spectrum licenses that were transferred to the Company by an entity controlled by the Former SPSI CEO in connection with the June 2013 settlement of all outstanding claims and disputes with the Former SPSI CEO and parties related to the Former SPSI CEO (see Note 11 – Other Commitments and Contingencies No impairment was recorded as of July 31, 2017 and 2016. Income Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in its assessment of a valuation allowance. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date of such change. The Company uses a two-step approach for recognizing and measuring tax benefits taken or expected to be taken in a tax return. The Company determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, the Company presumes that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information. Tax positions that meet the more-likely-than-not recognition threshold are measured to determine the amount of tax benefit to recognize in the financial statements. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in one or more of the following: an increase in a liability for income taxes payable, a reduction of an income tax refund receivable, a reduction in a deferred tax asset, or an increase in a deferred tax liability. The Company classifies interest and penalties on income taxes as a component of income tax expense. Contingencies The Company accrues for loss contingencies when both (a) information available prior to issuance of the financial statements indicates that it is probable that a liability had been incurred at the date of the financial statements and (b) the amount of loss can reasonably be estimated. When the Company accrues for loss contingencies and the reasonable estimate of the loss is within a range, the Company records its best estimate within the range. When no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount in the range. The Company discloses an estimated possible loss or a range of loss when it is at least reasonably possible that a loss may have been incurred. Loss per Share Basic loss per share is computed by dividing net income 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 loss per share is computed in the same manner as basic loss 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 and warrants using the treasury stock method, unless the effect of such increase is anti-dilutive. The following table sets forth the number of Class B shares of common stock issuable upon the exercise of stock options and warrants which were excluded from the diluted per share calculation even though the exercise price was less than the average market price of the Class B common shares and non-vested restricted Class B common stock because the effect of including these potential shares was anti-dilutive due to the net loss incurred during that period: Years Ended July 31, 2017 2016 2015 (in thousands) Stock options 29 3 4 Warrants 65 — — Non-vested restricted Class B common stock 251 196 331 Shares excluded from the calculations of diluted loss per share 345 199 335 The following table sets forth the number of stock options to purchase Class B common stock which were excluded from the diluted per share calculation because the exercise price was greater than the average market price of the Class B common shares: Years Ended July 31, 2017 2016 2015 (in thousands) Warrants 7 — — Stock options — 88 — Non-vested restricted Class B common stock — — — Shares excluded from the calculations of diluted loss per share 7 88 — For the years ended July 31, 2017, 2016 and 2015, 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. Stock-Based Compensation The Company accounts for stock-based compensation in accordance with FASB ASC 718, “ Compensation - Stock Compensation The Company accounts for equity instruments issued in exchange for the receipt of goods or services from other than employees in accordance with FASB ASC 505, “ Equity Allowance for Doubtful Accounts The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The allowance is determined based on known troubled accounts, historical experience and other currently available evidence. Doubtful accounts are written-off upon final determination that the trade accounts will not be collected. The change in the allowance for doubtful accounts is as follows: Year ended July 31, Balance at Additions Deductions Balance at 2017 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ — $ 19 $ — $ 19 2016 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ — $ — $ — $ — Inventory Inventory, consisting solely of finished goods, is valued at the lower of cost or market.

Verizon Merger Agreement

Verizon Merger Agreement	12 Months Ended

Verizon Merger Agreement [Abstract]
Verizon Merger Agreement	Note 2—Verizon Merger Agreement On April 9, 2017, the Company signed the Agreement and Plan of Merger with AT&T Inc. and Switchback Merger Sub Inc. (the “AT&T Merger Agreement”). Among the terms, the AT&T Merger Agreement allowed the Company to terminate the AT&T Merger Agreement if the Company received a better offer (as defined). If such an offer was accepted, the Company would be required to pay AT&T a termination fee of $38 million. The Company did receive better offers from Verizon. On May 11, 2017, the Company entered into an Agreement and Plan of Merger (the “Verizon Merger Agreement”) with Verizon, a Delaware corporation, and Waves Merger Sub I, Inc., a Delaware corporation and a direct, wholly-owned subsidiary of Verizon (“Merger Sub”). The Verizon Merger Agreement called for Verizon to pay the $38 million to AT&T on behalf of the Company. Such payment was made by Verizon on May 11, 2017. Per Section 7.3(b) of the Verizon Merger Agreement, “Termination by the Company,” if the Company terminated the Verizon agreement as a result of receiving a Superior Proposal (as defined), before the Requisite Company Vote (as defined) being obtained, then the Company would repay Verizon the $38 million paid to AT&T. This contingency would create a liability to us only if we accepted a Superior Proposal. As of July 31, 2017, the Company did not receive and did not enter into an agreement for a Superior Proposal. The Requisite Company Vote occurred on August 2, 2017, as further noted below. As a result, the Company never owed the termination fee to Verizon. Pursuant to the Verizon Merger Agreement, among other things, Merger Sub will be merged with and into the Company (the “Merger”) with the Company being the surviving corporation of the Merger. At the effective time of the Merger (the “Effective Time”), each share of Class A common stock, par value $0.01 per share, of the Company and each share of Class B common stock, par value $0.01 per share, of the Company (collectively, the “Shares”) issued and outstanding immediately prior to the Effective Time (other than Shares owned by Verizon, Merger Sub or any other direct or indirect subsidiary of Verizon, and Shares owned by the Company or any direct or indirect subsidiary of the Company, and in each case not held on behalf of third parties) will be converted into the right to receive a number of validly issued, fully paid in and nonassessable shares of common stock of Verizon (“Verizon Shares”) equal to the quotient determined by dividing $184.00 by the five (5)-day volume-weighted average per share price ending on the second full trading day prior to the Effective Time, rounded to two decimal points, of Verizon Shares on the New York Stock Exchange (the “Verizon Share Value”) and rounded to the nearest ten-thousandth of a share (collectively and in the aggregate, the “Merger Consideration”). It is the Company’s intention that (i) the Merger shall qualify as a “reorganization” within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended, and the Treasury regulations promulgated thereunder, and (ii) the Verizon Merger Agreement shall constitute a plan of reorganization within the meaning of Treasury Regulation Section 1.368-2(g), as noted in the Verizon Merger Agreement. The board of directors (the “Board”) of the Company has unanimously approved the Verizon Merger Agreement and determined that the Verizon Merger Agreement and the transactions contemplated thereby, including the Merger, are fair to, and in the best interests of, the Company and its stockholders, and has resolved to recommend that the Company’s stockholders adopt the Verizon Merger Agreement. The Company has agreed, subject to certain exceptions with respect to unsolicited proposals, not to directly or indirectly solicit competing acquisition proposals or to participate in any discussions concerning, or provide non-public information in connection with, any unsolicited acquisition proposals. However, the Board may, subject to certain conditions, at any time before the Company’s stockholders vote to adopt the Verizon Merger Agreement, change its recommendation in favor of approval of the Verizon Merger Agreement if, in connection with receipt of a superior proposal or an event occurring after the date of the Verizon Merger Agreement with respect to the Company, it determines in good faith, after consultation with its financial advisors and outside legal counsel, that the failure to take such action would be inconsistent with its fiduciary duties to the Company’s stockholders under applicable law. On August 2, 2017, the Company held a special meeting of its stockholders to vote on a proposal to adopt the Verizon Merger Agreement. At such meeting, the proposal to adopt the Verizon Merger Agreement was approved with 89% of the votes entitled to be cast at the special meeting voting; and of the votes cast, approximately 99% of the votes cast in favor of the proposal to adopt the Verizon Merger Agreement. That approval terminated the Board’s ability to consider unsolicited acquisition proposals, change its recommendation of the Merger and terminate the Verizon Merger Agreement in connection therewith. The completion of the Merger is subject to the satisfaction or waiver of customary closing conditions, including: (i) adoption of the Verizon Merger Agreement by the Company’s stockholders; (ii) receipt of regulatory approvals, including receipt of consent to the Merger from the FCC and the expiration or termination of any waiting period under the Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (“HSR”); (iii) there being no law or injunction prohibiting consummation of the transactions contemplated under the Verizon Merger Agreement; (iv) the effectiveness of a registration statement on Form S-4 relating to the Merger; (v) subject to specified materiality standards, the continuing accuracy of certain representations and warranties of each party; (vi) continued compliance by each party in all material respects with its covenants; (vii) no event having occurred that has had, or would reasonably be likely to have, a Material Adverse Effect (as defined in the Verizon Merger Agreement) on the Company; (viii) receipt by the Company of an opinion from its tax counsel to the effect that the Merger will qualify as a “reorganization” for United States federal income tax purposes within the meaning of Section 368(a) of the Internal Revenue Code of 1986, as amended; (ix) receipt of approval for listing the Verizon Shares on the New York Stock Exchange and the NASDAQ Global Select Market, subject to official notice of issuance; and (x) the FCC consent referred to in clause (ii) of this paragraph having become a Final Order (as defined in the Verizon Merger Agreement). The Company and Verizon filed notification and report forms under the HSR Act with the Federal Trade Commission and the Antitrust Division of the Department of Justice on May 19, 2017. The HSR Act waiting period expired on June 19, 2017, and the condition for HSR Act clearance was satisfied. On June 1, 2017, the Company and Verizon submitted applications to the FCC seeking consent to transfer control of the Company’s spectrum licenses to Verizon. For further discussion, see Note 11 – Regulatory Enforcement The Company has made customary representations and warranties in the Verizon Merger Agreement. The Verizon Merger Agreement also contains customary covenants and agreements, including covenants and agreements relating to the conduct of the Company’s business between the date of the signing of the Verizon Merger Agreement and the closing of the transactions contemplated under the Verizon Merger Agreement. The representations and warranties made by the Company are qualified by disclosures made in its disclosure schedules and SEC filings. None of the representations and warranties in the Verizon Merger Agreement survive the closing of the transactions contemplated by the Verizon Merger Agreement. The Verizon Merger Agreement contains certain termination rights for both the Company and Verizon including upon (i) an uncured breach by the other party which results in the failure of a closing condition, (ii) the failure to receive the approval of the Verizon Merger Agreement by the Company’s stockholders, and (iii) the Company’s Board changing its recommendation in favor of the Verizon Merger Agreement. The Verizon Merger Agreement further provides that, upon termination of the Verizon Merger Agreement, under certain circumstances following a change in recommendation by the Company in connection with its receipt of a superior proposal or due to an Intervening Event (as defined in the Verizon Merger Agreement), the Company may be required to pay Verizon a termination fee equal to $38 million. The requisite vote of the Company’s stockholders occurred on August 2, 2017. As a result, the Company never owed the termination fee to Verizon. Either the Company or Verizon may terminate the Verizon Merger Agreement if the completion of the Merger has not occurred on or before February 12, 2018 (as it may be extended as provided below, the “Termination Date”); provided, however, that if regulatory approvals have not been obtained and all other conditions to closing have been satisfied or waived, the Termination Date will automatically be extended for an additional one hundred and eighty days. In addition, Verizon is required to pay the Company an aggregate amount equal to $85 million (the “Parent Termination Fee”) in the event that the Merger has not closed by the extended Termination Date, and all conditions to closing other than receipt of FCC consent or HSR approval (or expiration of the waiting period under the HSR) have been satisfied or waived. In the event that the Verizon Merger Agreement is terminated other than as a result of Verizon’s breach or under circumstances in which Verizon is required to pay the Parent Termination Fee, the Company will be required to pay Verizon an amount equal to the AT&T Termination Fee (as defined in the Verizon Merger Agreement) paid by Verizon on the Company’s behalf. The Verizon Merger Agreement was attached as Exhibit 2.1 to the Form 8-K filed by the Company with the SEC on May 11, 2017 to provide investors and security holders with information regarding its terms. It is not intended to provide any other factual information about the Company, Verizon or Merger Sub, or to modify or supplement any factual disclosures about the Company or Verizon in their public reports filed with the SEC. The Verizon Merger Agreement includes representations, warranties and covenants of the Company, Verizon and Merger Sub made solely for purposes of the Verizon Merger Agreement and which may be subject to important qualifications and limitations agreed to by the Company, Verizon and Merger Sub in connection with the negotiated terms of the Verizon Merger Agreement. Moreover, some of those representations and warranties may not be accurate or complete as of any specified date, may be subject to a contractual standard of materiality different from those generally applicable to the Company’s or Verizon’s SEC filings or may have been used for purposes of allocating risk among the Company, Verizon and Merger Sub rather than establishing matters as facts. The foregoing summary of the Verizon Merger Agreement and the transactions contemplated thereby does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Verizon Merger Agreement, which was attached as Exhibit 2.1 to the Form 8-K filed by the Company with the SEC on May 11, 2017. In addition, Howard Jonas, who has the right to vote a majority of the voting power of the Company’s common stock, entered into a voting agreement with Verizon concurrently with the entry into the Verizon Merger Agreement (the “Voting Agreement”). The Voting Agreement provided that Mr. Jonas (holding his Class A shares through a trust) would vote his Class A shares in the Company in favor of the Merger and the other transactions contemplated in the Verizon Merger Agreement, on the terms and subject to the conditions set forth in the Voting Agreement. The Voting Agreement would terminate automatically upon the earliest to occur of (i) the effective time of the Merger, (ii) the valid termination of the Verizon Merger Agreement pursuant to Article VII thereof, (iii) a change of recommendation by the Board in the event of a Superior Proposal or Intervening Event, (iv) any change being made to the terms of the Verizon Merger Agreement that would terminate the Trust’s or Mr. Jonas’s obligation to vote in favor of the Merger (on the terms and subject to the conditions in the Verizon Merger Agreement) or (v) February 12, 2018. The Company is not a party to the Voting Agreement. On May 11, 2017, the AT&T Merger Agreement was terminated in its entirety by the Company. In addition, on May 11, 2017, Verizon paid to AT&T, on behalf of the Company, the $38 million Company Termination Fee (as defined in the AT&T Merger Agreement) concurrently with the termination of the AT&T Merger Agreement pursuant to the terms and conditions thereof. The $38 million fee would be repaid by the Company to Verizon if the Company terminated the Verizon Merger Agreement as the result of the Company receiving a superior offer before the Requisite Company Vote (as defined) being obtained. As of July 31, 2017, the Company did not receive a superior offer and as such, the $38 million fee was not owed to Verizon. On August 2, 2017, the Requisite Company Vote occurred approving the Verizon Merger Agreement, and Howard Jonas voted his shares in favor of the Verizon Merger Agreement. That approval terminated the Board’s ability to consider unsolicited acquisition proposals, change its recommendation of the Merger and terminate the Verizon Merger Agreement in connection therewith. The Company has incurred costs totaling approximately $2,847,000 related to the Verizon Merger Agreement. These costs were included in selling, general and administrative expenses. If the Merger is consummated, the Company estimates that it will incur various fees and expenses, which will be paid by Verizon. These fees and expenses include but are not limited to the following: 1. Payment to the FCC of 20% of the Proceeds (as defined in the FCC Consent Decree) (see Note 11 – Regulatory Enforcement 2. Financial advisor and legal fees - $63.9 million 3. Balance owed to PTPMS Communications, LLC (“PTPMS”) (see Note 11 – PTPMS 4. Balance owed to Former Chief Executive Officer of Straight Path Spectrum (the “Former SPSI CEO”) - $3.0 million (see Note 11 – Other Commitments and Contingencies 5. Severance and retention payments to certain members of management – see below In connection with its entry into the AT&T Merger Agreement and then the Verizon Merger Agreement, the Company approved severance arrangements for Davidi Jonas (“Jonas”), the Company’s Chief Executive Officer and President, Jonathan Rand (“Rand”), the Company’s Chief Financial Officer and treasurer, Zhouyue (Jerry) Pi (“Pi”), the Company’s Chief Technology Officer, and David Breau (“Breau”), the Company’s General Counsel (each an “Executive”, and collectively, the “Executives”). The severance arrangements provide that if, within two years following the consummation of the Merger, the Company terminates an Executive’s employment without “Cause” or an Executive resigns for “Good Reason” (each such term to be defined in the severance agreements to be entered into prior to the consummation of the Merger), the Executive shall be entitled to receive a lump sum payment equal to one and one-half times (1.5x) (two and one-half times (2.5x) for Jonas) the sum of the Executive’s annual base salary and target bonus, subject to the execution of a release of claims. The Company also approved retention bonus payments for Jonas, Rand and Breau in the amounts of $1,800,000, $1,000,000 and $1,000,000, respectively. Subject to continued employment through the consummation of the Merger, such individuals shall be entitled to receive their retention bonus payment in a lump sum within thirty days following the consummation of the Merger.

Income Taxes [Abstract]
Income Taxes	Note 5—Income Taxes As a result of its corporate structure, 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 years ended July 31, 2017, 2016 and 2015 as it incurred a taxable loss in those years. In addition, there is a 100% valuation allowance against the net operating losses generated by Straight Path Spectrum at both July 31, 2017 and 2016. The operations of Straight Path IP Group are included in the consolidated tax return of Straight Path. There is no provision of current taxes for Straight Path for the years ended July 31, 2017, 2016 and 2015. In Fiscal 2014 and 2015, capital contributions were made to a wholly-owned limited liability company which allowed Straight Path to utilize certain suspended losses. The Company estimated that such suspended losses made available by the capital contributions would 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. In addition, there is a 100% valuation allowance against the net deferred tax assets related to Straight Path at July 31, 2017 (see discussion below). The tax expense in Fiscal 2016 represents state income and franchise taxes. The benefit in Fiscal 2015 represents a federal refund from a prior year net of current state income and franchise taxes. Straight Path Ventures files its own tax returns. There is no provision for Straight Path Ventures for the years ended July 31, 2017, 2016 and 2015 as it incurred a taxable loss in those periods. In addition, since it is a partnership return, its results are passed to its partners, both of which are included in the consolidated tax return of Straight Path. The provision for income taxes for Fiscal 2015 consisted solely of certain state income taxes. The benefit from (provision for) income taxes consists of the following: Year ended July 31, (in thousands) 2017 2016 2015 Current: Federal $ — $ 39 $ — State and local (13 ) (35 ) (34 ) (13 ) 4 (34 ) Deferred: Federal — — (2,211 ) State and local — — (469 ) — — (2,680 ) INCOME TAX BENEFITS (PROVISION FOR INCOME TAXES) $ (13 ) $ 4 $ (2,714 ) Significant components of the Company’s deferred income tax assets and liabilities consist of the following: July 31, 2017 2016 Deferred income tax assets (liabilities): Net operating loss carryforward $ 74,292 $ 57,098 Accrued expenses 3,808 338 Stock based compensation (4,043 ) (464 ) Valuation allowance (74,057 ) (56,972 ) TOTAL NET DEFERRED INCOME TAX ASSETS (LIABILITIES) $ — $ — Because of its losses in the current and previous years, the Company concluded that it does not meet the criteria of more likely than not in order to utilize its deferred income tax assets in the foreseeable future for the Straight Path Spectrum line of business. Accordingly, the Company recorded a 100% valuation allowance against its deferred income tax assets. Straight Path Ventures is treated as a partnership for Federal income tax purposes. Straight Path Ventures has generated material losses that are “suspended” in accordance with section 704(d) of the Internal Revenue Code, and accordingly, are not available to the Company unless the Company causes all or part of the suspension to be reversed. As a consequence of the “suspension,” no deferred tax asset is reflected herein with respect of such net operating losses. If any part of such net operating losses does become available, it is recorded as a tax benefit in the period used. In Fiscal 2014 and 2015, approximately $3.0 million of suspended losses became available to offset taxable income but the Company did not recognize a benefit due to taxable losses incurred. As discussed below, the Internal Revenue Service is in the process of auditing the Fiscal 2015 return and is anticipated to be completed in the near future. The differences between income taxes expected at the federal statutory income tax rate and income taxes provided are as follows: Year ended July 31, (in thousands) 2017 2016 2015 Federal income tax at statutory rate $ 15,524 $ 2,939 $ (262 ) Permanent differences (759 ) (2 ) 1,048 Valuation allowance (17,085 ) (3,394 ) (3,500 ) Other 15 (3 ) — State and local income tax, net of federal benefit 2,292 464 — PROVISION FOR (INCOME TAXES) INCOME TAX BENEFITS $ (13 ) $ 4 $ (2,714 ) At July 31, 2017, the Company had net operating loss carryforwards of approximately $187 million. These net operating losses are split $170 million from Straight Path Spectrum and $17 million from Straight Path IP Group (Straight Path). These carryforward losses are available to offset future taxable income. The net operating loss carryforwards will start to expire in Fiscal 2022, with the loss from Fiscal 2017 expiring in Fiscal 2037. The change in the valuation allowance for deferred income taxes was as follows: Year ended July 31, Balance at Additions Deductions Balance at 2017 Reserves deducted from deferred income taxes, net: Valuation allowance $ 56,972 $ 17,085 $ — $ 74,057 2016 Reserves deducted from deferred income taxes, net: Valuation allowance $ 53,681 $ 3,394 $ (103 ) $ 56,972 2015 Reserves deducted from deferred income taxes, net: Valuation allowance $ 50,191 $ 3,500 $ (10 ) $ 53,681 The table below summarizes the change in the balance of unrecognized income tax benefits: Year ended July 31, (in thousands) 2017 2016 2015 Balance at beginning of period $ 215 $ 210 $ — Additions based on tax positions related to the current period — — — Additions for tax positions of prior periods 6 5 210 Reductions for tax positions of prior periods — — — Settlements — — — Lapses of statutes of limitations — — — Balance at end of period $ 221 $ 215 $ 210 All of the unrecognized income tax benefits at July 31, 2017 and 2016 would have affected the Company’s effective income tax rate if recognized. The Company does not expect the total amount of unrecognized tax benefits to significantly increase or decrease within the next twelve months. In the years ended July 31, 2017, 2016 and 2015, the Company recorded interest on income taxes of $6,000, $5,000 and $0, respectively. As of July 31, 2017 and 2016, there was no accrued interest included in current income taxes payable. The Company’s various federal, state, and local tax returns for Fiscal 2015 through Fiscal 2017 remain subject to examination. The Internal Revenue Service is in the process of auditing the Fiscal 2015 return and is anticipated to be completed in the near future. The Company does not expect any adjustment to have a material impact on the Company’s consolidated financial statements.

Loan Payable

Loan Payable	12 Months Ended

Loan Payable [Abstract]
Loan Payable	Note 8—Loan Payable On February 6, 2017, the Company entered into a loan agreement (“Loan Agreement”) with a syndicate of investors (the “Lenders”) pursuant to which the Company borrowed $17.5 million (the “Loan Amount”). The loan matures on December 29, 2017. Interest accrued at a rate of 5% per annum until June 30, 2017 and then increased to a rate of 10% per annum. Other significant terms of the Loan Agreement include the following: 1. $15 million of the Loan Amount is be used to pay the Initial Civil Penalty provided for in the Consent Decree in accordance with the payment requirements set forth in the Consent Decree. The remainder of the Loan Amount is being used for general corporate purposes and working capital needs. 2. Upon funding the Loan Amount, the Lenders received warrants to purchase 252,161 shares of the Company’s Class B common stock with an aggregate exercise price equal to $7.5 million based on an exercise price of $34.70 per share. The exercise price was based on the weighted average trading price for the Class B common stock for the five trading days preceding the funding date. The warrants expire at the earlier of December 31, 2018 or a liquidation event (as defined). Warrants to purchase 147,682 shares of Class B common stock were exercised by the holders in the third quarter of Fiscal 2017 (see Note 9 - Equity). 3. From and after June 30, 2017, the Lenders are entitled to receive additional warrants on a monthly basis with an aggregate value equal to 7.5% (the rate was 10% for July 2017 and August 2017) of the then outstanding Loan Amount. The exercise price for such warrants is based on the weighted average trading price for the Class B common stock for the ten trading days preceding the warrant issue date. Under this provision, the Lenders received the following warrants: a. On July 3, 2017, the Lenders received warrants to purchase 6,899 shares of the Company’s Class B common stock with an exercise price of $179.62 per share. b. On August 1, 2017, the Lenders received warrants to purchase 6,911 shares of the Company’s Class B common stock with an exercise price of $179.26 per share. c. On September 1, 2017, the Lenders received warrants to purchase 5,188 shares of the Company’s Class B common stock with an exercise price of $179.18. d. On October 2, 2017, the Lenders received warrants to purchase 5,152 shares of the Company’s Class B common stock with an exercise price of $180.48. 4. To the extent the warrants are held by a Lender at the time of exercise, the exercise price will be paid by the reduction of the outstanding Loan Amount. As of July 31, 2017, the Loan Amount was reduced by $5,125,000 as the result of the exercise of 147,682 warrants received by the Lenders upon making the loan (see Note 9). There were no additional warrant exercises for the period from August 1, 2017 to the date of the filing of this report. 5. The Loan Agreement is secured by a first priority security interest in primarily all of the assets of the Company. The fair value of the warrants at the date of grants was estimated using the Black-Scholes option pricing model with the following assumptions: Risk-free interest rate 1.13 % Dividend yield 0 % Volatility 5% - 96.68 % Expected term (in years) 1.92 Expected volatility is based on historical volatility of the Company’s common stock; the expected term until exercise represents the weighted-average period of time that options granted are expected to be outstanding giving consideration to vesting schedules and the Company’s historical exercise patterns; and the risk-free interest rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. The Company has not paid any dividends since its inception and does not anticipate paying any dividends for the foreseeable future, so the dividend yield is assumed to be zero. The Company also incurred cash costs of $80,000 in connection with the loan. The fair value of the warrants and the cash loan costs are amortized to interest expense over the term of the Loan Agreement. Amortization amounted to $2,286,000 for Fiscal 2017. Interest expense incurred under the Loan Agreement totaled $402,000 for Fiscal 2017. At July 31, 2017, loans payable were $11,274,000 which is net of unamortized debt discounts of $1,101,000.

The dividend to Straight Path of $4,772,004 was not paid as of the filing of this report but is eliminated in producing the Company’s consolidated financial statements. The Company does not anticipate paying any additional dividends on its common stock until it achieves sustainable profitability (after satisfying all of our operational needs, including payments to the Former SPSI CEO) and retains certain minimum cash reserves. Following that time, we will retain sufficient cash to provide for investment in growth opportunities and provide for the creation of long-term stockholder value, particularly through development of the Straight Path Spectrum and Straight Path Ventures businesses and possibly the acquisition of complementary businesses or assets. However, the Company does not intend to retain earnings beyond those needs and beyond what it believes it can effectively deploy, and the Company expects that such additional resources would be returned to stockholders via distributions or other means. The payment of dividends in any specific period will be at the sole discretion of the Company’s Board. Except for any special dividend that may be paid in connection with the transactions contemplated by the IDT Term Sheet discussed in Note 3, the Verizon Merger Agreement does not permit the Company to pay any additional dividends on its common stock.

The weighted-average grant date fair value of stock options granted during Fiscal 2016 was $4.41. There were no grants during Fiscal 2017 and Fiscal 2015. The Company estimated the fair value of options granted in Fiscal 2016 using the Black-Scholes option pricing model with the following assumptions: Risk-free interest rate 0.65 % Dividend yield 0 % Volatility 65.6 % Expected term (in years) 1.8 The expected life is the number of years that the Company estimates, based upon history, that options will be outstanding prior to exercise or forfeiture. Expected life is determined using the “simplified method” permitted by Staff Accounting Bulletin No. 107. The Company did not use the volatility rate of its common stock price. Instead, the volatility rate was based on a blended rate of the stock prices of companies deemed comparable to the Company. The total intrinsic value of options exercised during Fiscal 2017, Fiscal 2016, and Fiscal 2015 was approximately $1,802,000, $46,000 and $204,000, respectively. The aggregate intrinsic value in the table above represents the total intrinsic value, based on the Company’s closing stock price of $179.40 as of July 31, 2017, $18.24 as of July 31, 2016, and $23.57 as of July 31, 2015, which would have been received by the option holders had all option holders exercised their options as of that date.

Commitments and Contingencies [Abstract]
Commitments and Contingencies	Note 11—Commitments and Contingencies Legal Proceedings Regulatory Enforcement On January 11, 2017, the Company entered into the Consent Decree with the FCC settling the FCC’s investigation regarding Straight Path Spectrum’s spectrum licenses on the terms specified therein. Material terms of the Consent Decree include the following: 1. The FCC agreed to terminate its investigation. 2. Straight Path Spectrum agreed to surrender 93 of its 828 39 GHz economic area spectrum licenses to the FCC, as well as 103 rectangular service area licenses that the Company does not believe were material assets of the Company. 3. Straight Path Spectrum keeps all of its 28 GHz spectrum licenses. 4. Straight Path Spectrum is barred from entering into any new leases of its spectrum. 5. The Company agreed to pay the Initial Civil Penalty of $15 million in four installments as follows - $4 million on or before February 11, 2017; $4 million on or before April 11, 2017; $3.5 million on or before July 11, 2017; and $3.5 million on or before October 11, 2017. If the Company sells its remaining spectrum licenses (see below) prior to the due date of any installation payment, any remaining installation payments will become due on the date of such closing. 6. The Company agreed to submit to the FCC an application for approval of a sale of its remaining 39 GHz and 28 GHz spectrum licenses on or before January 11, 2018 and pay the FCC 20% of the proceeds from such the sale(s). 7. If the Company does not submit to the FCC an application for approval of a sale of its remaining spectrum licenses on or before January 11, 2018, the Company will pay an additional penalty of $85 million or surrender its remaining spectrum licenses. The Company recorded the Initial Civil Penalty of $15 million and the associated expense is classified as “civil penalty – FCC consent decree” on the consolidated statement of operations. The first three installments of the Initial Civil Penalty totaling $11.5 million were paid. The remaining liability is classified as “FCC consent decree payable” on the consolidated balance sheet. As of July 31, 2017, FCC consent decree payable was $3.5 million. As discussed in Note 2, the Company entered into the Verizon Merger Agreement. If the Merger is consummated, the fee owed per Item 6 above will be paid by Verizon as part of the Merger. On June 1, 2017, the Company and Verizon submitted applications to the FCC seeking consent to transfer control of the Company’s spectrum licenses to Verizon. The transfer of control applications was referenced on an FCC Public Notice on July 21, 2017, and the FCC established a pleading cycle, allowing interested parties to comment on why the transaction should be approved or denied. Petitions to deny the application were due on August 11, 2017, oppositions to those petitions due on August 18, 2017 and replies to those oppositions were due on August 25, 2017. Three parties – the Competitive Carriers Association, Public Knowledge and New America’s Open Technology Institute, and U.S. Telepacific – filed petitions to deny the transaction, change its recommendation of the Merger and terminate the Verizon Merger Agreement in connection therewith. The petitioning parties argued that approval of the transaction would result in excessive spectrum aggregation in local markets, undermine competition in 5G mobile broadband by precluding others from acquiring 5G spectrum, improperly benefit Straight Path in violation of the FCC Consent Decree, and terminate existing spectrum leases. In response, the Company and Verizon argued that approval of this transaction will advance 5G leadership. The Company and Verizon explained that the transaction will not create any competitive issues, and, once Verizon acquires the spectrum, it will remain below the FCC’s spectrum threshold for competitive review across the vast majority of markets. The Company and Verizon argued that opponents of the transaction cannot use the transaction to challenge the Consent Decree, review of this transaction must be limited to the transaction, and that the terms of the Consent Decree are final and are the result of the FCC’s deliberate and sound policy choices. The Company and Verizon clarified that Verizon will honor the Company’s contractual obligations under existing spectrum leases with third parties. In their replies, the parties opposing the transaction maintained their prior arguments, and also argued that the FCC should auction the Company’s spectrum licenses instead of approving the transaction and that the transaction is not in the public interest. On September 7, 2017, and September 21, 2017, Hammer Fiber Optics filed ex parte letters noting a number of meetings with staff from the FCC’s Wireless Telecommunications Bureau and Office of Engineering and Technology, and meetings with Chairman Ajit Pai’s, Commissioner Mignon Clyburn’s, and Commissioner Brendan Carr’s legal advisors. In the letters, Hammer discussed the relevance of the transaction with respect to the service it is providing, and also stated that it did not object to Verizon’s acquisition of our LMDS spectrum. The Company believes that the submission to the FCC by the Company and Verizon of an application to transfer control of the Company’s spectrum licenses to Verizon satisfies the requirement under the Consent Decree as described in Item 6 above. However, if the Merger is not completed for any reason, there is no guarantee that the FCC would not seek to require the Company to pay the $85 million penalty or seek the forfeiture of the Company’s remaining spectrum licenses. If the penalty is imposed by the FCC, there is no guarantee that the Company will be able to obtain sufficient financing to pay the additional $85 million or repay the remaining amount due of the $17.5 million loan from the Lenders. A failure by the Company to comply with these requirements could lead to a default by the Company under the Consent Decree, loss of the Company’s remaining spectrum licenses, either of which will have a material adverse effect on the Company’s financial condition and results of operations. Shareholder Litigation On July 5, 2017, JDS1 LLC, a putative Straight Path stockholder, filed a class action and derivative complaint in the Delaware Court of Chancery captioned JDS1, LLC v.

On May 6, 2016, Cisco and Avaya also filed notices of appeal. As discussed above, the CAFC affirmed the PTAB’s decision on June 23, 2017. On October 31, 2014, LG Electronics Inc. et al. (“LG”), Toshiba Corporation et al. (“Toshiba”), Vizio, Inc. (“Vizio”), and Hulu LLC (“Hulu”) filed three petitions with the PTAB for IPR of certain claims of the ‘704, ‘469, and ‘121 Patents.

On November 24, 2015, the PTAB granted related petitions filed by Verizon Services Corp. and Verizon Business Network Services Inc. (the “Verizon affiliates”) to join for the ‘704 and ‘469 Patents. On May 9, 2016, the PTAB issued a final written decision holding that the petitioners failed to show that any claims of the ‘704 Patent were unpatentable. The PTAB also held that the petitioners failed to show that the majority of the claims of the ‘469 and ‘121 Patents were unpatentable. On May 20, 2016, the petitioners filed a notice of appeal to the CAFC, and this appeal was consolidated with the appeal of the Samsung IPR discussed above. As discussed above, the CAFC affirmed the PTAB’s decision on June 23, 2017. On September 28, 2015, Cisco, Avaya, and the Verizon affiliates filed a petition for an IPR with the PTAB for all claims of U.S. Patent No. 6,701,365 (the “‘365 Patent”). On April 6, 2016, the PTAB denied the petition, finding that the petitioners had not demonstrated a reasonable likelihood that any challenged claim was unpatentable. This decision was not appealed to the CAFC. Ex Parte Re-examination On September 13, 2017, Apple, Inc. (“Apple”) filed a request for ex parte Patent Enforcement Following the CAFC’s decision in Sipnet and the PTAB’s decisions in the related IPRs, Straight Path IP Group has taken steps to re-commence its patent enforcement actions in federal district court that had been stayed or dismissed without prejudice during the pendency of the Sipnet Appeal and related IPRs. On August 1, 2013, Straight Path IP Group filed complaints in the United States District Court for the Eastern District of Virginia against LG, Toshiba, and Vizio alleging infringement of the ‘704, ‘469, and ‘121 Patents and seeking damages related to such infringement. The actions were consolidated (the “consolidated action”) and assigned to Judge Anthony J. Trenga. In October 2014, Hulu intervened in the consolidated 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 in the United States District Court for the Northern District of California seeking declaratory relief of non-infringement of the ‘704, ‘469, and ‘121 Patents based in part on the allegations related to the consolidated action in Virginia (the “Amazon action”). On December 5, 2014, Straight Path IP Group filed a motion to dismiss Amazon’s complaint, or in the alternative, to transfer venue to the Eastern District of Virginia. On May 28, 2015, the California court transferred the Amazon action to Virginia, and the Virginia court later formally severed the Amazon action from the consolidated action. The action was stayed during the pendency of the two successive CAFC appeals. On September 13, 2017, the Court held a scheduling conference, and the pretrial conference is set for January 18, 2018. 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 alleging infringement of the ‘704, ‘469, and ‘121 Patents and seeking damages related to such infringement. The action was stayed during the pendency of the two successive CAFC appeals. On September 11, 2017, the Court reopened the case and placed it back on the active docket. On September 24, 2014, Straight Path IP Group filed complaints against each of Apple, Avaya, and 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 Straight Path IP Group’s patents (the ‘704, ‘469, ‘121, ‘208 Patents); (b) Avaya’s IP telephony, video conference, and telepresence products such as its Aura Platform infringe four of the Straight Path IP Group’s patents (the ‘704, ‘469, ‘121, and ‘365 Patents); and (c) Cisco’s IP telephony, video conference, and telepresence products such as the Unified Communications Solutions infringe four of Straight Path IP Group’s patents (the ‘704, ‘469, ‘121, and ‘365 Patents). 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 June 21, 2016, Straight Path IP Group filed new complaints against Avaya and Cisco alleging that certain of their products infringe four of Straight Path IP Group’s patents. On August 5, 2016, Avaya filed its answer, affirmative defenses, and counterclaims for declaratory judgments of noninfringement and invalidity of Straight Path IP Group’s patents, and the parties have commenced discovery. Also on August 5, 2016, Cisco filed its answer and affirmative defenses, and the parties have commenced discovery. On June 24, 2016, Straight Path IP Group filed a new complaint against Apple alleging that its FaceTime product infringes five of Straight Path IP Group’s patents. On August 5, 2016, Apple filed a partial motion to dismiss as well as its answer, affirmative defenses, and counterclaims for declaratory judgments of noninfringement and invalidity of Straight Path IP Group’s patents. Following oral argument, on October 21, 2016, the court granted in part and denied in part Apple’s motion. The court dismissed one claim as to the ‘469 Patent but denied Apple’s motion with respect to the other four patents at issue in the litigation. Expert discovery is underway in the Apple and Cisco actions. On January 19, 2017, Avaya filed voluntary petitions under chapter 11 of the U.S. Bankruptcy Code in the U.S. Bankruptcy Court for the Southern District of New York. On May 2, 2017, Straight Path IP Group filed a proof of claim in the Avaya bankruptcy proceeding. On September 26, 2014, Straight Path IP Group filed a complaint against the Verizon affiliates and Verizon Communications in the United States District Court for the Southern District of New York. Straight Path IP Group claims the defendants’ telephony products such as its Advanced Communications Products, including Unified Communications and Collaboration and VOIP infringe on the ‘704, ‘469, and ‘365 Patents. On November 24, 2014, Straight Path IP Group dismissed the complaint without prejudice subject to a confidential standstill agreement with the defendants. On June 7, 2016, Straight Path IP Group filed a new complaint in the United States District Court for the Southern District of New York against the original Verizon parties as well as Verizon affiliate Cellco Partnership d/b/a Verizon Wireless, alleging that defendants’ IP telephony products such as FIOS Digital Voice, Unified Communications and Collaboration, Verizon Enterprise Solutions VoIP, Virtual Communications Express, Voice over LTE, and related hardware and software infringe the ‘704, ‘469 and ‘365 Patents. On August 5, 2016, Verizon filed its answer and affirmative defenses, and the parties have commenced discovery. On September 13, 2016, Verizon filed a motion to stay the litigation pending a decision from the CAFC in the appeal of the Samsung IPR. On October 18, 2016, the court granted Verizon’s motion and stayed the litigation. On July 5, 2017, the court lifted the stay and set a scheduling conference for September 15, 2017, but on September 11, 2017, the court stayed the case until December 8, 2017 at Straight Path IP Group’s request. 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. Straight Path IP Group recently agreed to amend the retainer agreement with one of these law firms. Among other things, under the amended agreement, beginning on October 2, 2017, Straight Path IP Group will pay one of the law firms a monthly fee of $100,000 that is non-refundable but creditable against any contingency fee payment that may be due to the law firm in the future. Settlement of Claims with IDT and Sale of Straight Path IP Group On April 9, 2017, the Company and IDT entered into the IDT Term Sheet, providing for the settlement and mutual release of potential indemnification claims asserted by each of the Company and IDT in connection with liabilities that may exist or arise relating to the subject matter of the investigation by (including but not limited to fines, fees or penalties imposed by) the FCC (the “Mutual Release”). For further discussion, please see Note 3 - Settlement of Claims with IDT and Sale of Straight Path IP Group PTPMS On May 29, 2012, the Company acquired certain licenses from PTPMS under an asset purchase agreement (the “PTPMS agreement”). Under the terms of that agreement, PTPMS is entitled to a “profit share” of 20% of the net proceeds from any partition, sale, assignment, transfer of control, disaggregation, or lease of, or any other commercial operating arrangement involving any or all of the licenses acquired from PTPMS (the “Profit Share”). For further discussion, see Note 2 – Verizon Merger Agreement PTPMS Communications, LLC v. Straight Path Communications Inc Other Legal In addition to the foregoing, the Company may from time to time be subject to other legal proceedings that arise in the ordinary course of business. Lease Commitments The Company is party to a lease agreement for its corporate headquarters in Glen Allen, Virginia for a term of one year beginning on June 1, 2014 and ending on May 31, 2015 at a monthly rent of $575. The Company extended the lease from May 31, 2015 to May 31, 2017 and again to May 31, 2019. The annual rent under the newest lease is approximately $7,700 per year. In October 2014, the Company entered into a lease agreement for a satellite office in Englewood Cliffs, New Jersey for three years commencing on November 1, 2014 and ending on October 31, 2017 at an annual rent of $37,200. In March 2015, the term of the lease was extended to April 30, 2018. Effective December 1, 2015, the Company began leasing a laboratory in Plano, Texas. The lease term expires on December 31, 2018 and the average annual rental under the lease is approximately $18,000. Effective August 1, 2013, the Company began leasing space on a roof for some of its telecom equipment as part of its spectrum operations. The monthly rental is currently $600. In addition, the Company currently leases space on two additional roofs for some of its telecom equipment as part of its Spectrum operations. The total monthly rental for these two roofs is $500. All three leases continue on a month-to-month basis until terminated by either party with 30 days’ notice. Rental expense under the operating leases was $51,758, $51,543 and $40,685 in Fiscal 2017, Fiscal 2016, and Fiscal 2015, respectively. Future minimum rental commitments of non-cancelable operating leases are as follows as of July 31, 2017: Years ending July 31, 2018 $ 53,456 2019 14,039 $ 67,495 FCC License Renewal Our spectrum licenses in the LMDS and 39 GHz bands have historically been granted for ten-year terms. On April 20, 2016, and based on our submission of a renewal application and substantial service demonstration, the FCC granted our application to renew our LMDS BTA license for the LMDS A1 band (27.5 – 28.35 GHz) that covers parts of the New York City BTA for a ten-year period, until February 1, 2026. We have 15 other LMDS A1 licenses; nine of these licenses currently have a renewal date of August 10, 2018, and six of these licenses have a renewal date of September 21, 2018. However, following the adoption of the Upper Microwave Flexible Use (“UMFU”) Report and Order, we are only required to submit an application for renewal at those deadlines; we are not required to submit a substantial service demonstration for these licenses until the next build-out date specified in the UFMU Report and Order, which is June 1, 2024. It is likely that the FCC will issue new licenses for the LMDS A1 spectrum on the one hand and the A2 and A3 licenses on the other, with separate renewal and substantial service deadlines for each (as noted above, the substantial service demonstration dates for the A1 licenses will be June 1, 2024). Of the 15 BTAs in which we hold LMDS A2 band (29.1 – 29.25 GHz) and A3 band (31.075 – 31.225 GHz) spectrum, nine licenses currently have a renewal and likely substantial service deadline of August 10, 2018 and six of these licenses currently have a renewal and likely substantial service deadline of September 21, 2018. The UMFU Report and Order does not affect the LMDS B band spectrum. Of our 117 LMDS B band (31.0 – 31.075 GHz and 31.225 – 31.300 GHz) spectrum, five licenses currently have a renewal and substantial service deadline of August 10, 2018 and 112 licenses currently have a renewal and substantial service deadline of September 21, 2018. On August 3, 2017, the FCC adopted new rules governing the process by which licensees may seek renewal of their authorizations. However, for the licenses we hold, those rules do not go into effect until January 1, 2023, after all of licenses will be renewed. The UMFU Report and Order substantial service deadline of June 1, 2024 also applies to our 735 39 GHz licenses, which currently have a renewal deadline of October 18, 2020. For further discussion, please see “ Regulatory Enforcement Other Commitments and Contingencies Former SPSI CEO 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 $77,000 was incurred to the Former SPSI CEO for this obligation for Fiscal 2017, approximately $48,000 for Fiscal 2016 and approximately $8,000 for Fiscal 2015.

Business Segment Information [Abstract]
Business Segment Information	Note 14—Business Segment Information Prior to November 1, 2015, the Company had two reportable business segments, Straight Path Spectrum, which holds, leases, and markets fixed and mobile wireless spectrum, and Straight Path IP Group, which holds intellectual property primarily related to communications over computer networks, and the licensing and other businesses related to this intellectual property. Effective November 1, 2015, a third segment, referred to as Straight Path Ventures, was designated. Straight Path Ventures develops next generation wireless technology for 39 GHz at the Company’s Gigabit Mobility Lab in Plano, Texas. 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. The Company allocates all of the corporate general and administrative expenses of Straight Path to Straight Path IP Group, Straight Path Spectrum, and Straight Path Ventures based upon the relative time of management and other corporate resources expended relative to each business as well as the revenues earned by each division. For all periods through January 31, 2016, these were allocated 80% to Straight Path IP Group and 20% to Straight Path Spectrum. No expenses were allocated to Straight Path Ventures because the amount of management’s time and other resources dedicated to Straight Path Ventures were deemed to be immaterial. Commencing on February 1, 2016, these expenses are being allocated 20% to Straight Path IP Group and 80% to Straight Path Spectrum, except for the following: 1. Expenses related to the Gigabit Mobility Lab are being allocated 100% to Straight Path Ventures; 2. Employment expenses of our Chief Technology Officer are being allocated 20% to Straight Path IP Group, 20% to Straight Path Spectrum, and 60% to Straight Path Ventures; 3. Employment expenses related to one employee are being allocated 20% to Straight Path Spectrum and 80% to Straight Path Ventures; 4. Employment expenses related to several other employees are being allocated 100% to Straight Path Spectrum. The changes in allocations were brought about by the expiration of the licensed patents held by Straight Path IP Group and the increase in activities of Straight Path Ventures. Straight Path IP Group recognized revenues over the terms of the settlements and license agreements related to such patents entered into in prior periods. With the expiration of the key patents and the increase in activities of Straight Path Ventures, the Company determined to modify the allocation, and in light of the anticipated level of activity in Straight Path IP Group’s enforcement activities and Straight Path Ventures’ development activities, the Company determined that a general 20% allocation to Straight Path IP Group, subject to the specific allocations listed above, represented the appropriate split in light of all factors. Operating results for the business segments of the Company were as follows: Straight Straight Straight Path Path Path Spectrum IP Group Ventures Total Year Ended July 31, 2017 Revenues $ 658 $ — $ — $ 658 Loss from operations (34,976 ) (6,098 ) (1,937 ) (43,011 ) Year Ended July 31, 2016 Revenues $ 461 $ 1,695 $ — $ 2,156 Loss from operations (5,508 ) (2,688 ) (891 ) (9,087 ) Year Ended July 31, 2015 Revenues $ 426 $ 12,814 $ — $ 13,240 Income (loss) from operations (1,641 ) 1,907 — 266 Total assets for the business segments of the Company were as follows: Straight Straight Straight Path Path Path Spectrum IP Group Ventures Total (in thousands) Total assets July 31, 2017 $ 8,054 $ 2,696 $ 1,100 $ 11,850 July 31, 2016 10,174 2,223 1,100 13,497 None of the Company’s revenues were generated outside of the United States.

Description of Business and Summary of Significant Accounting Policies [Abstract]
Use of Estimates	Use of Estimates The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Actual results may differ from those estimates.
Revenue Recognition	Revenue Recognition Straight Path Spectrum lease revenues are recognized on a straight-line basis over the contractual lease period, which generally range from one to five years. Revenues from sale of rights in FCC licenses are recognized upon execution of the agreement by both parties, provided that the amounts are fixed or determinable, there are no significant undelivered obligations and collectability is reasonably assured. Straight Path Spectrum recorded the amounts that the former Chief Executive Officer of Straight Path Spectrum (the “Former SPSI CEO”) was entitled to, related to leases, in “Selling, general and administrative” expense, in the same period the related revenues were recognized. Straight Path Ventures develops next generation wireless technology and has no revenue at this time. Straight Path IP Group licensed its portfolio of patents to companies who used these patents in the provision of their product(s) and/or service(s). The contractual terms of the license agreements entered into in prior periods generally provided for payments over an extended period of time. For the licensing agreements with fixed royalty payments, Straight Path IP Group generally recognized revenue on a straight-line basis over the contractual term of the license, once collectability of the amounts was reasonably assured. For the licensing agreements with variable royalty payments which are based on a percentage of sales, Straight Path IP Group earned royalties at the time that the customers’ sales occurred. Straight Path IP Group’s customers, however, did not report and pay royalties owed for sales in any given period until after the conclusion of that period. As Straight Path IP Group was unable to estimate the customers’ sales in any given period to determine the royalties due to Straight Path IP Group, it recognized royalty revenues when sales and royalties were reported by customers and when other revenue recognition criteria were met. In addition, Straight Path IP Group entered into certain settlements of patent infringement disputes. The amount of consideration received upon any settlement (including but not limited to past royalty payments and future royalty payments) was allocated to each element of the settlement based on the fair value of each element. In addition, revenues related to past royalties were recognized upon execution of the agreement by both parties, provided that the amounts were fixed or determinable, there were no significant undelivered obligations and collectability was reasonably assured. Straight Path IP Group did not recognize any revenues prior to execution of the agreement since there was no reliable basis on which it could estimate the amounts for royalties related to previous periods or assess collectability.
Direct Cost of Revenues	Direct Cost of Revenues Direct cost of revenues for Straight Path Spectrum consists primarily of network and connectivity costs. Such costs are charged to expense as incurred. Direct cost of revenues for Straight Path IP Group consisted of legal expenses directly related to revenues from litigation settlements.
Cash Equivalents and Concentrations of Credit Risk	Cash Equivalents and Concentrations of Credit Risk The Company considers all highly liquid investments with an original maturity of three months or less when purchased to be cash equivalents. Cash equivalents consist of money market accounts. The Company maintains principally all cash and cash equivalent balances in various financial institutions, which at times may exceed the amounts insured by the Federal Deposit Insurance Corporation. The exposure to the Company is solely dependent upon daily bank balances and the respective strength of the financial institutions. The Company has not incurred any losses on these accounts.
Inventory	Inventory Inventory, consisting solely of finished goods, is valued at the lower of cost or market determined on the first-in, first-out (FIFO) basis. The Company periodically evaluates inventory items and establishes reserves for obsolescence accordingly. The Company also reserves for excess quantities, slow-moving goods, and for other impairment of value based upon assumptions of future demand and market conditions. No reserve for obsolescence was recorded as of July 31, 2017.
Intangible Assets	Intangible Assets Intangible assets consist primarily of the cost of the wireless spectrum licenses that were transferred to the Company by an entity controlled by the Former SPSI CEO in connection with the June 2013 settlement of all outstanding claims and disputes with the Former SPSI CEO and parties related to the Former SPSI CEO (see Note 11 – Other Commitments and Contingencies No impairment was recorded as of July 31, 2017 and 2016.
Income Taxes	Income Taxes The Company recognizes deferred tax assets and liabilities for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of existing assets and liabilities and their respective tax bases. A valuation allowance is provided when it is more likely than not that some portion or all of a deferred tax asset will not be realized. The ultimate realization of deferred tax assets depends on the generation of future taxable income during the period in which related temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future taxable income, and tax planning strategies in its assessment of a valuation allowance. Deferred tax assets and liabilities are measured using the enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date of such change. The Company uses a two-step approach for recognizing and measuring tax benefits taken or expected to be taken in a tax return. The Company determines whether it is more-likely-than-not that a tax position will be sustained upon examination, including resolution of any related appeals or litigation processes, based on the technical merits of the position. In evaluating whether a tax position has met the more-likely-than-not recognition threshold, the Company presumes that the position will be examined by the appropriate taxing authority that has full knowledge of all relevant information. Tax positions that meet the more-likely-than-not recognition threshold are measured to determine the amount of tax benefit to recognize in the financial statements. The tax position is measured at the largest amount of benefit that is greater than 50 percent likely of being realized upon ultimate settlement. Differences between tax positions taken in a tax return and amounts recognized in the financial statements will generally result in one or more of the following: an increase in a liability for income taxes payable, a reduction of an income tax refund receivable, a reduction in a deferred tax asset, or an increase in a deferred tax liability. The Company classifies interest and penalties on income taxes as a component of income tax expense.
Contingencies	Contingencies The Company accrues for loss contingencies when both (a) information available prior to issuance of the financial statements indicates that it is probable that a liability had been incurred at the date of the financial statements and (b) the amount of loss can reasonably be estimated. When the Company accrues for loss contingencies and the reasonable estimate of the loss is within a range, the Company records its best estimate within the range. When no amount within the range is a better estimate than any other amount, the Company accrues the minimum amount in the range. The Company discloses an estimated possible loss or a range of loss when it is at least reasonably possible that a loss may have been incurred.
Loss per Share	Loss per Share Basic loss per share is computed by dividing net income 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 loss per share is computed in the same manner as basic loss 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 and warrants using the treasury stock method, unless the effect of such increase is anti-dilutive. The following table sets forth the number of Class B shares of common stock issuable upon the exercise of stock options and warrants which were excluded from the diluted per share calculation even though the exercise price was less than the average market price of the Class B common shares and non-vested restricted Class B common stock because the effect of including these potential shares was anti-dilutive due to the net loss incurred during that period: Years Ended July 31, 2017 2016 2015 (in thousands) Stock options 29 3 4 Warrants 65 — — Non-vested restricted Class B common stock 251 196 331 Shares excluded from the calculations of diluted loss per share 345 199 335 The following table sets forth the number of stock options to purchase Class B common stock which were excluded from the diluted per share calculation because the exercise price was greater than the average market price of the Class B common shares: Years Ended July 31, 2017 2016 2015 (in thousands) Warrants 7 — — Stock options — 88 — Non-vested restricted Class B common stock — — — Shares excluded from the calculations of diluted loss per share 7 88 — For the years ended July 31, 2017, 2016 and 2015, 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.
Stock-Based Compensation	Stock-Based Compensation The Company accounts for stock-based compensation in accordance with FASB ASC 718, “ Compensation - Stock Compensation The Company accounts for equity instruments issued in exchange for the receipt of goods or services from other than employees in accordance with FASB ASC 505, “ Equity
Allowance for Doubtful Accounts	Allowance for Doubtful Accounts The allowance for doubtful accounts reflects the Company’s best estimate of probable losses inherent in the accounts receivable balance. The allowance is determined based on known troubled accounts, historical experience and other currently available evidence. Doubtful accounts are written-off upon final determination that the trade accounts will not be collected. The change in the allowance for doubtful accounts is as follows: Year ended July 31, Balance at Additions Deductions Balance at 2017 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ — $ 19 $ — $ 19 2016 Reserves deducted from accounts receivable: Allowance for doubtful accounts $ — $ — $ — $ —
