⁽¹⁾	Participating securities consist of shares of unvested restricted stock and unvested time-based restricted stock units.

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 June 30				Nine Months Ended June 30
	2014		2013		2014		2013
	(Dollars in millions)
Calculation of undistributed earnings:
Net income attributable to Cabot Corporation	$	52	$	59	$	168	$	106
Less: Dividends declared on common stock		14		13		40		39
Less: Dividends declared on participating securities		—		—		—		—

Undistributed earnings	$	38	$	46	$	128	$	67

Allocation of undistributed earnings:
Undistributed earnings allocated to common shareholders	$	37	$	45	$	126	$	66
Undistributed earnings allocated to participating shareholders		1		1		2		1

Undistributed earnings	$	38	$	46	$	128	$	67

⁽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 Deferred Compensation and Supplemental Retirement 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, 2014, 142,115 and 203,019 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. 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.
