A $1.00 increase (decrease) in the assumed initial public offering price of $20.00 per share, which is the midpoint of the range listed on the cover page of this prospectus, would increase (decrease) the pro forma as adjusted amount of each of cash and cash equivalents, additional paid-in capital, total stockholders equity and total capitalization by approximately $6.0 million, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.
Update to Dilution
The disclosure set forth in the fourth paragraph, the table immediately following the fourth paragraph, the fifth paragraph and the sixth paragraph in the section of the Preliminary Prospectus captioned Dilution has been revised as follows:
After giving effect to the sale of 6,500,000 shares of common stock that we are offering at an assumed initial public offering price of $20.00 per share, which is the midpoint of the range listed on the cover page of this prospectus, and after deducting the estimated underwriting discounts and commissions and estimated offering expenses payable by us, our pro forma as adjusted net tangible book value as of September 30, 2014 would have been approximately $180.6 million, or approximately $7.86 per share. This amount represents an immediate increase in pro forma net tangible book value of $4.06 per share to our existing stockholders and an immediate dilution in pro forma net tangible book value of approximately $12.14 per share to new investors purchasing shares of common stock in this offering. We determine dilution by subtracting the pro forma, as adjusted net tangible book value per share after this offering from the amount of cash that a new investor paid for a share of common stock. The following table illustrates this dilution:
Assumed initial public offering price per share |
$ | 20.00 | ||||||
Net tangible book value per share as of September 30, 2014 |
$ | 10.30 | ||||||

A $1.00 increase (decrease) in the assumed initial public offering price of $20.00 per share, which is the midpoint of the range listed on the cover page of this prospectus, would increase (decrease) the pro forma as adjusted net tangible book value per share after this offering by approximately $0.26, and dilution in pro forma net tangible book value per share to new investors by approximately $0.74, assuming that the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting estimated underwriting discounts and commissions and estimated offering expenses payable by us.
If the underwriters exercise their option to purchase additional shares of our common stock in full in this offering, the pro forma as adjusted net tangible book value after the offering would be $8.29 per share, the increase in pro forma net tangible book value per share to existing stockholders would be $4.49 and the dilution to new investors would be $11.71 per share, in each case assuming an initial public offering price of $20.00 per share, which is the midpoint of the range listed on the cover page of this prospectus.
