EXPLANATORY NOTE

This Registration Statement on Form S-8 is being filed by Interval Leisure Group, Inc., a Delaware corporation (the “Registrant”), to register 567,046 shares of common stock, par value $0.01 per share (“Common Stock”), available for issuance under the terms of the Interval Leisure Group, Inc. 2008 Annual and Stock Incentive Plan, as amended (the “2008 Plan”), and issuance of 100,000 shares of Common Stock under the Interval Leisure Group, Inc. Deferred Compensation Plan for Non-Employee Directors (the “Director Plan”). Prior to December 31, 2015, there were stock options under the 2008 Plan that had been issued to employees of companies that were previously owned by our former parent company, IAC/InterActiveCorp, in connection with our August 2008 spin-off that were not eligible for registration on Form S-8. All currently outstanding awards under the 2008 Plan and the Director Plan are eligible for registration on Form S-8.

PART II

INFORMATION REQUIRED IN THE REGISTRATION STATEMENT

Item 3. Incorporation of Documents by Reference

The following documents previously filed by the Registrant (Commission File No. 001-34062) with the Commission are hereby incorporated by reference in this Registration Statement as of their respective dates and shall be deemed a part hereof:

a) the Registrant’s Annual Report on Form 10-K for the year ended December 31, 2015 filed on February 26, 2016;

b)	the description of the Registrant’s Common Stock contained in its Registration Statement on Form 8-A (File No. 001-34062) filed with the SEC on August 5, 2008, including any amendments or reports filed for the purpose of updating such description; and
c)	the description of our Rights Agreement contained in our registration statement on Form 8-A filed with the SEC on June 11, 2009, including any amendments or reports filed for the purpose of updating such description.

All reports and documents subsequently filed by the Registrant pursuant to Sections 13(a), 13(c), 14 and 15(d) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), after the date of this Registration Statement, but prior to the filing of a post-effective amendment which indicates that all securities offered hereby have been sold or which deregisters all securities then remaining unsold, shall be deemed to be incorporated by reference herein and to be a part hereof from the date of the filing of such documents.

Any statement contained herein or in any document incorporated or deemed to be incorporated by reference herein shall be deemed to be modified or superseded for purposes of this Registration Statement to the extent that a statement contained herein or in any other subsequently filed document which also is or is deemed to be incorporated by reference herein modifies or supersedes such statement. Any statement so modified or superseded shall not be deemed, except as so modified or superseded, to constitute a part of this Registration Statement.

Item 4. Description of Securities

Not applicable.

Item 5. Interests of Named Experts and Counsel

The validity of the Common Stock offered hereby has been passed upon by Victoria J. Kincke, Senior Vice President, General Counsel and Secretary of the Registrant. Ms. Kincke is an employee of the Registrant and as such participates in the Registrant’s employee benefit plans and owns securities of the Registrant, including restricted stock units.

Item 6. Indemnification of Directors and Officers

Section 145 of the Delaware General Corporation Law (“DGCL”) provides that a corporation may indemnify directors and officers as well as other employees and individuals against expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement in connection with any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative, in which such person is made a party by reason of the fact that the person is or was a director, officer, employee or agent of the corporation (other than an action by or in the right of the corporation—a “derivative action”), if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reasonable cause to believe such person’s conduct was unlawful. A similar standard is applicable in the case of derivative actions, except that indemnification only extends to expenses (including attorneys’ fees) incurred in connection with the defense or settlement of such action, and the statute requires court approval before there can be any indemnification where the person seeking indemnification has been found liable to the corporation. The statute provides that it is not exclusive of other indemnification that may be granted by a corporation’s by-laws, disinterested director vote, shareholder vote, agreement or otherwise.

The Registrant’s Amended and Restated Certificate of Incorporation provides that no director shall be liable to the Registrant or its shareholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation on liability is not permitted under the DGCL, as now in effect or as amended. Currently, Section 102(b)(7) of the DGCL requires that liability be imposed for the following:

· any breach of the director’s duty of loyalty to the Registrant or its shareholders;

· any act or omission not in good faith or which involved intentional misconduct or a knowing violation of law;

· unlawful payments of dividends or unlawful stock repurchases or redemptions as provided in Section 174 of the DGCL; and

· any transaction from which the director derived an improper personal benefit.

The Registrant’s Amended and Restated Certificate of Incorporation and Amended and Restated By-laws provide that, to the fullest extent authorized by the DGCL, as now in effect or as amended, we will indemnify any person who was or is a party or is threatened to be made a party to any action, suit or proceeding by reason of the fact that such person, or a person of whom he or she is the legal representative, is or was a director or officer of the Registrant, or by reason of the fact such person, or a person of whom he or she is the legal representative is or was serving, at the Registrant’s request, as a director, officer, or trustee of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans maintained or sponsored by the Registrant. To the extent authorized by the DGCL, the Registrant will indemnify such persons against all expenses, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid or to be paid in settlement) reasonably incurred or suffered by such persons in connection with such service. Any amendment of these provisions will not reduce the indemnification obligations of the Registrant relating to actions taken before such amendment.

The Registrant has obtained policies that insure its directors and officers and those of its subsidiaries against certain liabilities they may incur in their capacity as directors and officers. Under these policies, the insurer, on behalf of the Registrant, also may pay amounts for which the Registrant has granted indemnification to the directors or officers.

Item 9. Undertakings

(a)  The undersigned Registrant hereby undertakes:

(1)     To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i)     to include any prospectus required by Section 10(a)(3) of the Securities Act;

(ii)     to reflect in the prospectus any facts or events arising after the effective date of the Registration Statement (or most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the Registration Statement; and

(iii)     to include any material information with respect to the plan of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration Statement;

provided, however, that paragraphs (a)(1)(i) and (a)(1)(ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed with or furnished to the Commission by the Registrant pursuant to Section 13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement;

(2)     that, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof; and

(3)     to remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(b)     The undersigned Registrant hereby undertakes that, for purposes of determining any liability under the Securities Act, each filing of the Registrant’s annual report pursuant to Section 13(a) or Section 15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(c)     Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the Registrant pursuant to the foregoing provisions, or otherwise, the Registrant has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the Registrant of expenses incurred or paid by a director, officer or controlling person of the Registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the Registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SIGNATURES

Pursuant to the requirements of the Securities Act of 1933, the Registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-8 and has duly caused this Registration Statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Miami, State of Florida, on February 26, 2016.
