Diluted net income (loss) per share (1)	$	0.10		$	0.16		$	0.35		$	(0.20	)
Shares excluded from diluted net income (loss) per share computations (2)	—			—			—			9,886,530

(1) Diluted net income (loss) per share is equal to basic net income (loss) per share for the periods presented due to the allocation of earnings to participating securities under the two-class method of calculating basic net income (loss) per share causing basic net income (loss) per share to be lower than diluted net income (loss) per share calculated under the treasury-stock method.

(2) Shares issuable upon conversion of preferred stock and non-vested shares were excluded from the computation of diluted net income (loss) per share because their effect would have been anti-dilutive.
