	Following is a discussion regarding the Company’s use of financial instruments:

Hedging Activities – As of March 31, 2018, the notional amount of foreign currency hedge positions was approximately $1.6 billion, and commodity hedge contracts totaled approximately $140 (primarily 53 million pounds of copper and aluminum). All derivatives receiving deferral accounting are cash flow hedges. The majority of hedging gains and losses deferred as of March 31, 2018 are expected to be recognized over the next 12 months as the underlying forecasted transactions occur. Gains and losses on foreign currency derivatives reported in Other deductions, net reflect hedges of balance sheet exposures that do not receive deferral accounting. The following gains and losses are included in earnings and other comprehensive income (OCI) for the three and six months ended March 31, 2018 and 2017:



		Into Earnings									Into OCI
		2nd Quarter					Six Months				2nd Quarter			Six Months
Gains (Losses)	Location	2017			2018		2017		2018		2017	2018		2017	2018
Commodity	Cost of sales	$	4		6		2		11		5	(9	)	15	4
Foreign currency	Sales, cost of sales	(7		)	—		(17	)	—		20	8		22	(4	)
Foreign currency	Other deductions, net	(6		)	(12	)	—		(12	)
Total		$	(9	)	(6	)	(15	)	(1	)	25	(1	)	37	—

Regardless of whether derivatives receive deferral accounting, the Company expects hedging gains or losses to be essentially offset by losses or gains on the related underlying exposures. The amounts ultimately recognized will differ from those presented above for open positions, which remain subject to ongoing market price fluctuations until settlement. Derivatives receiving deferral accounting are highly effective and no amounts were excluded from the assessment of hedge effectiveness. Hedge ineffectiveness was immaterial for the three and six months ended March 31, 2018 and 2017.

Fair Value Measurement – Valuations for all derivatives and the Company's long-term debt fall within Level 2 of the GAAP valuation hierarchy. As of March 31, 2018, the fair value of long-term debt was $4,013, which exceeded the carrying value by $198. At March 31, 2018, the fair values of commodity contracts and foreign currency contracts were reported in other current assets and accrued expenses. Valuations of derivative contract positions are summarized below:



	September 30, 2017				March 31, 2018
	Assets			Liabilities	Assets	Liabilities
Foreign Currency		$	26	18	22	13
Commodity		$	12	—	6	2

Counterparties to derivatives arrangements are companies with investment-grade credit ratings. The Company has bilateral collateral arrangements with counterparties with credit rating-based posting thresholds that vary depending on the arrangement. If credit ratings on the Company's debt fall below pre-established levels, counterparties can require immediate full collateralization of all derivatives in net liability positions. The maximum amount that could potentially have been required was $2. The Company also can demand full collateralization of derivatives in net asset positions should any counterparty credit ratings fall below certain thresholds. No collateral was posted with counterparties and none was held by the Company as of March 31, 2018.
