Capital Stock	Capital Stock Effective upon the closing of our initial public offering ("IPO") in November 2013, our authorized share capital consists of 233.3 million shares of a single class of common shares (the "Common Shares"). The Common Shares have no pre-emptive rights or other rights to subscribe for additional shares, and no rights of redemption, conversion or exchange. Under certain circumstances and subject to the provisions of Bermuda law and our bye-laws, we may be required to make an offer to repurchase shares held by members. The Common Shares rank pari passu with one another in all respects as to rights of payment and distribution. In general, holders of Common Shares will have one vote for each Common Share held by them and will be entitled to vote, on a non-cumulative basis, at all meetings of shareholders. In the event that a shareholder is considered a 9.5% Shareholder under our bye-laws, such shareholder's votes will be reduced by whatever amount is necessary so that after any such reduction the votes of such shareholder will not result in any other person being treated as a 9.5% Shareholder with respect to the vote on such matter. Under these provisions certain shareholders may have their voting rights limited to less than one vote per share, while other shareholders may have voting rights in excess of one vote per share. Prior to the IPO, our authorized share capital consisted of Class A common shares, Class B-1 common shares and Class B-2 common shares. The Class A common shares ranked senior to the Class B-1 common shares and the Class B-2 common shares in all respects as to rights of payment and distribution. The Class B-1 common shares and the Class B-2 common shares ranked junior to the Class A common shares and pari passu with one another in all respects as to rights of payment and distribution. The holders of Class A common shares were entitled to receive cumulative compounding dividends prior and in preference to any declaration or payment of any dividend on any other class of shares in the capital of Essent Group, at the rate of 10% of the Original Class A Issue Price per annum, compounded annually, on each outstanding Class A common share. Any dividend or other distribution declared or paid on any Class B common shares shall have been ratably declared and paid on all of the outstanding Class A common shares (based on "as-if-converted" to Class B-1 common share amounts) at the same time as such dividend is paid on such Class B common shares. Upon the closing of our IPO, all outstanding Class A common shares and Class B-2 common shares that were eligible for vesting under the 2009 Restricted Share Plan were converted into 64.7 million Common Shares after giving effect to a 2 for 3 share split. All of the remaining Class B-2 common shares that were not eligible for vesting under the 2009 Restricted Share Plan were forfeited. In our IPO, we issued and sold approximately 20.0 million Common Shares at a public offering price of $17.00 per share and certain selling shareholders sold approximately 2.7 million Common Shares. We did not receive any proceeds from the sale of shares by the selling shareholders. The total net proceeds from the IPO were $313.7 million after deducting underwriting discounts commissions and other offering expenses. In November 2014, Essent Group completed the sale of 6.0 million Common Shares in a public offering at a price of $22.25 per share and certain selling shareholders sold 7.8 million Common Shares. We did not receive any proceeds from the sale of shares by the selling shareholders. The total net proceeds from this offering were approximately $126.7 million after deducting underwriting discounts, commissions and other offering expenses.
