Equity [Abstract]
Stockholders' Equity	Stockholders’ Equity On February 13, 2013, we completed our IPO by issuing 4,666,667 shares of our Class A common stock, par value $0.001 per share, at a price to the public of $14.00 per share of Class A common stock. In addition, we issued 8,666,667 shares of our Class B common stock, of which 8,580,000 shares of Class B common stock were obtained by HPI, and 86,667 shares of Class B common stock were obtained by Health Plan Intermediaries Sub, LLC (“HPIS”), of which HPI is the managing member. In addition, we granted the underwriters of the IPO the right to purchase additional shares of Class A common stock to cover over-allotments (the “over-allotment option”). Our authorized capital stock consists of 100,000,000 shares of Class A common stock, par value $0.001 per share, 20,000,000 shares of Class B common stock, par value $0.001 per share, and 5,000,000 shares of preferred stock, par value $0.001 per share. Class A Common Stock and Class B Common Stock Each share of Class A common stock and Class B common stock entitles its holders to one vote per share on all matters to be voted upon by the stockholders, and holders of each class will vote together as a single class on all such matters. Holders of shares of our Class A common stock and Class B common stock vote together as a single class on all matters presented to our stockholders for their vote or approval, except as otherwise required by applicable law. As of June 30, 2017, the Class A common stockholders had 76.4% of the voting power in HII and the Class B common stockholders had 23.6% of the voting power in HII. Holders of shares of our Class A common stock have 100% of the economic interest in HII. Holders of Class B common stock do not have an economic interest in HII. The determination to pay dividends, if any, to our Class A common stockholders will be made by our Board of Directors. We do not, however, expect to declare or pay any cash or other dividends in the foreseeable future on our Class A common stock, as we intend to reinvest any cash flow generated by operations in our business. We may enter into credit agreements or other borrowing arrangements in the future that prohibit or restrict our ability to declare or pay dividends on our Class A common stock. In the event of liquidation, dissolution, or winding up of HII, the holders of Class A common stock are entitled to share ratably in all assets remaining after payment of liabilities, subject to prior distribution rights of preferred stock, if any, then outstanding. The holders of our Class A common stock have no preemptive or conversion rights or other subscription rights. There are no redemption or sinking fund provisions applicable to the Class A common stock. The rights, preferences and privileges of holders of our common stock will be subject to those of the holders of any shares of our preferred stock we may issue in the future. Class B common stockholders will not be entitled to any dividend payments. In the event of any dissolution, liquidation, or winding up of our affairs, whether voluntary or involuntary, after payment of our debts and other liabilities and making provision for any holders of our preferred stock that have a liquidation preference, our Class B common stockholders will not be entitled to receive any of our assets. In the event of our merger or consolidation with or into another company in connection with which shares of Class A common stock and Class B common stock (together with the related membership interests) are converted into, or become exchangeable for, shares of stock, other securities or property (including cash), each Class B common stockholder will be entitled to receive the same number of shares of stock as is received by Class A common stockholders for each share of Class A common stock, and will not be entitled, for each share of Class B common stock, to receive other securities or property (including cash). No holders of Class B common stock will have preemptive rights to purchase additional shares of Class B common stock. Exchange Agreement On February 13, 2013, we entered into an exchange agreement (the “Exchange Agreement”) with the holders of the Series B Membership Interests of HPIH (“Series B Membership Interests”). All of the Series B Membership Interests are held by Health Plan Intermediaries, LLC (“HPI”) and Health Plan Intermediaries Sub, LLC (“HPIS”), which are two entities owned by Michael Kosloske, the founder and a director of our company. Pursuant to and subject to the terms of the Exchange Agreement and the amended and restated limited liability company agreement of HPIH, holders of Series B Membership Interests, at any time and from time to time, may exchange one or more Series B Membership Interests, together with an equal number of shares of our Class B common stock, for shares of our Class A common stock on a one-for-one basis, subject to equitable adjustments for stock splits, stock dividends and reclassifications. See Note 9 from our December 31, 2016 audited consolidated financial statements included in our Annual Report on Form 10-K for the year ended December 31, 2016 for further information on the Exchange Agreement. On February 1, 2014, a registration statement on Form S-3 became effective under which we registered 8,566,667 shares of our Class A common stock for resale from time to time by HPI and HPIS, of which all such shares are issuable upon the exchange of an equivalent number of Series B Membership Interests (together with an equal number of shares of our Class B common stock). On March 13, 2017, HPI and HPIS (the “Selling Stockholders”) completed a secondary underwritten public offering of 3,000,000 shares of our Class A common stock under the above-described Form S-3 registration statement. In connection with the offering, on March 8, 2017, we entered into an underwriting agreement with Canaccord Genuity Inc., Cantor Fitzgerald & Co., Northland Securities, Inc., and Lake Street Capital Markets, LLC, collectively as the underwriters, and the Selling Stockholders. Immediately prior to the completion of the offering, we issued 3,000,000 shares of Class A common stock to the Selling Stockholders. In exchange for the issuance of the shares, we immediately acquired 3,000,000 Series B Membership Interests, together with an equal number of shares of our Class B common stock from the Selling Stockholders. These Series B Membership Interests were immediately recapitalized into Series A Membership Interests in HPIH. The Selling Stockholders agreed to immediately after the exchange sell to the underwriter for resale all 3,000,000 shares of Class A common stock at a public offering price of $14.00 per share ($13.16 per share, net of underwriting discounts), for net proceeds of $39.5 million. No shares were sold by the Company in this offering. The acquisition of the Series B Membership Interests resulted in a decrease in noncontrolling interests with an offsetting increase in stockholders’ equity as of March 31, 2017 to reflect the decrease in the noncontrolling interest’s investment in HPIH. See Note 9 for further discussion on the tax receivable agreement we entered into with holders of Series B Membership Interests. Preferred Stock Our board of directors has the authority to issue shares of preferred stock in one or more series and to fix the rights, preferences, privileges and restrictions thereof, including dividend rights, dividend rates, conversion rights, voting rights, terms of redemption, redemption prices, liquidation preferences and the number of shares constituting any series or the designation of such series, without further vote or action by the stockholders. The issuance of preferred stock may have the effect of delaying, deferring or preventing a change in control of HII without further action by the stockholders and may adversely affect the voting and other rights of the holders of Class A common stock. At present, we have no plans to issue any preferred stock. Treasury Stock Treasury stock is recorded at cost. As of June 30, 2017 and December 31, 2016, we held 131,171 and 119,544 shares of treasury stock, respectively, recorded at a cost of $1.3 million and $1.1 million, respectively. Tax Obligation Settlements and Treasury Stock Transactions Treasury stock is recorded pursuant to the surrender of shares by certain employees to satisfy statutory tax withholding obligations on vested restricted stock awards. In addition, certain forfeited stock-based awards are transferred to and recorded as treasury stock, and certain restricted stock awards have been granted from shares in Treasury, and certain forfeited awards. During the six months ended June 30, 2017, 11,627 shares were transferred to Treasury as a result of surrendered shares of vested restricted stock awards. No shares were transferred to Treasury during the three months ended June 30, 2017 as a result of forfeitures of restricted stock awards. There was no other Treasury activity during the six months ended June 30, 2017. During the three and six months ended June 30, 2016, 2,399 and 6,531 shares, respectively, were transferred to Treasury as a result of surrendered shares of vested restricted stock awards and 1,623 and 15,280 options, respectively, were exercised and converted to Class A common stock out of treasury. During both the three and six months ended June 30, 2016, 3,200 shares, respectively, were transferred to Treasury as a result of forfeitures of restricted stock awards. Registration Statement on Form S-3 On May 5, 2017 the Company filed a registration statement on Form S-3, effective May 19, 2017, to offer and sell, from time to time, up to $150 million of any combination of debt securities, Class A Common Stock, preferred stock, warrants, subscription rights, units, or purchase contracts as described in the related prospectus. Securities may be sold in one or more classes or series and in amounts, at prices and on terms that we will determine at the times of the offerings and we may offer the securities independently or together in any combination for sale directly to purchasers or through underwriters, dealers or agents to be designated at a future date. We intend to use the net proceeds from the sale of the securities for general corporate purposes, including potentially expanding existing businesses, acquiring businesses and investing in other business opportunities. At June 30, 2017, the Company had not sold any securities under this Registration Statement.
