Update to Dilution
The disclosure set forth in the third, fourth, fifth and sixth paragraphs and the accompanying table section of the Preliminary Prospectus titled Dilution has been updated in its entirety to read as follows:
After giving effect to the sale of 6,000,000 shares of common stock in this offering at an assumed public offering price of $30.48 per share, which is the last reported sale price of our common stock on the NASDAQ Global Market on January 7, 2015, after deducting underwriting discounts and commissions and estimated offering expenses payable by us, our as adjusted net tangible book value as of September 30, 2014, would have been $236.3 million, or $6.42 per share. This represents an immediate increase in as adjusted net tangible book value of $4.31 per share to our existing stockholders and immediate dilution of $24.06 per share to investors purchasing common stock in this offering.
The following table illustrates this dilution on a per share basis to new investors:
Assumed public offering price per share |
$ | 30.48 | ||||||
Historic net tangible book value per share at September 30, 2014 |
$ | 2.11 | ||||||
Increase per share attributable to new investors |

6.42 | |||||||
|
|
|||||||
Dilution in adjusted net tangible book value per share to new investors |
$ | 24.06 | ||||||
|
|
Each $1.00 increase (decrease) in the assumed public offering price of $30.48 would increase (decrease) our as adjusted net tangible book value per share after this offering by $0.15 per share and the dilution to new investors by $0.85 per share, assuming the number of shares offered by us, as set forth on the cover page of this prospectus, remains the same and after deducting underwriting discounts and commissions.
If the underwriters exercise in full their option to purchase 900,000 additional shares from us, the as adjusted net tangible book value per share after giving effect to this offering would be $6.95 per share, representing an immediate increase to existing stockholders of $4.84 per share, and immediate dilution to investors in this offering of $23.53 per share.
