Undistributed earnings are the earnings which remain after dividends declared during the period are assumed to be distributed to the common and participating shareholders. Undistributed earnings are allocated to common and participating shareholders on the same basis as dividend distributions. The calculation of undistributed earnings is as follows:


	Three months ended				Nine months ended
	June 30				June 30
	2013		2012		2013		2012
	(Dollars in millions)				(Dollars in millions)
Calculation of undistributed earnings:
Net income attributable to Cabot Corporation	$	59	$	66	$	106	$	352
Less: Dividends declared on common stock		13		12		39		36
Less: Dividends declared on participating securities		—		—		—		—

Undistributed earnings	$	46	$	54	$	67	$	316

Allocation of undistributed earnings:
Undistributed earnings allocated to common shareholders	$	45	$	54	$	66	$	313
Undistributed earnings allocated to participating shareholders		1		—		1		3

Undistributed earnings	$	46	$	54	$	67	$	316

⁽²⁾	Undistributed earnings are adjusted for the assumed distribution of dividends to the dilutive securities, which are described in (3) below, and then reallocated to participating securities.

⁽³⁾

Represents incremental shares of common stock from the (i) assumed exercise of stock options issued under Cabot’s equity incentive plans; (ii) assumed issuance of shares to employees pursuant to the Company’s Supplemental Retirement Savings Plan; and (iii) assumed issuance of shares under outstanding performance-based restricted stock unit awards issued under Cabot’s equity incentive plans. For the three and nine months ended June 30, 2013, 308,000 incremental shares of common stock were not included in the calculation of diluted earnings per share because the inclusion of these shares would have been antidilutive. For the three and nine months ended June 30, 2012, 236,000 and 392,000 incremental shares of common stock, respectively, were not included in the calculation of diluted earnings per share because the inclusion of these shares would have been antidilutive.
