Schedule of weighted-average fair value and the assumptions used to measure fair value

	For the fiscal years ended October 31
	2015			2014			2013
Weighted-average fair value(1)		$ 8			$ 7			$ 4
Expected volatility(2)		26.8	%		33.1	%		41.7	%
Risk-free interest rate(3)		1.7	%		1.8	%		1.1	%
Expected dividend yield(4)		1.8	%		2.1	%		3.6	%
Expected term in years(5)		5.9			5.7			5.9

(1)	The weighted-average fair value was based on stock options granted during the period.
(2)	For all awards granted in fiscal 2015 and fiscal 2013, expected volatility was estimated using the implied volatility derived from options traded on HP's common stock. For awards granted in fiscal 2014, expected volatility for awards subject to service-based vesting was estimated using the implied volatility derived from options traded on HP's common stock, whereas for performance- contingent awards, expected volatility was estimated using the historical volatility of HP's common stock.
(3)	The risk-free interest rate was estimated based on the yield on U.S. Treasury zero-coupon issues.
(4)	The expected dividend yield represents a constant dividend yield applied for the duration of the expected term of the award.
(5)	For awards subject to service-based vesting, the expected term was estimated using historical exercise and post-vesting termination patterns; and for performance-contingent awards, the expected term represents an output from the lattice model.
