Discontinued Operations | Discontinued Operations On October 29, 2016, we entered into a Membership Interest Purchase Agreement (the Agreement) with CenterPoint Energy Services, Inc., a subsidiary of CenterPoint Energy, Inc. (CES) to sell all of the equity interests of AEM. The transaction closed on January 3, 2017, with an effective date of January 1, 2017. CES paid a cash purchase price of $38.3 million plus working capital of $109.0 million for total cash consideration of $147.3 million. Of this amount, $7.0 million was placed into escrow, to be paid to the Company within 24 months, net of any indemnification claims agreed upon between the two companies. In January 2018, $3.0 million of this escrowed amount was released and received by the Company. In January 2019, the remaining $4.0 million of this escrowed amount was released and received by the Company. We recognized a net gain of $0.03 per diluted share on the sale in the second quarter of fiscal 2017 and completed the working capital true–up during the third quarter of fiscal 2017. The operating results of our natural gas marketing reportable segment have been reported on the consolidated statements of comprehensive income as income from discontinued operations, net of income tax for the year ended September 30, 2017. Accordingly, expenses related to allocable general corporate overhead and interest expense are not included in these results. The decision to report this segment as a discontinued operation was predicated, in part, on the following qualitative and quantitative factors: 1) the disposal resulted in the company becoming a fully regulated entity; 2) the fact that an entire reportable segment was disposed and 3) the fact the disposed segment represented in excess of 30 percent of consolidated revenues over the last five fiscal years. The tables below set forth selected financial information related to discontinued operations. Operating expenses include operation and maintenance expense, provision for doubtful accounts, depreciation and amortization expense and taxes, other than income. The following table presents statement of comprehensive income data related to discontinued operations.
The following table presents statement of cash flow data related to discontinued operations.
Significant Accounting Policies Related to Discontinued Operations Except as noted below, AEM adhered to the same Significant Accounting Policies as described in Note 2. Revenue recognition — We adopted ASC 606 using the modified retrospective approach so AEM's revenue recognition was not impacted by the adoption of the new standard. Operating revenues for our natural gas marketing segment were recognized in the period in which actual volumes were transported and storage services were provided. Operating revenues for our natural gas marketing segment and the associated carrying value of natural gas inventory (inclusive of storage costs) were recognized when we sold the gas and physically delivered it to our customers. Operating revenues include realized gains and losses arising from the settlement of financial instruments used in our natural gas marketing activities. Gas stored underground — Gas stored underground was comprised of natural gas injected into storage to conduct the operations of the natural gas marketing segment. Our natural gas marketing segment utilized the average cost method; however, most of this inventory was hedged and was therefore reported at fair value at the end of each month. Property, plant and equipment — Natural gas marketing property, plant and equipment was stated at cost. Depreciation was generally computed on the straight-line method for financial reporting purposes based upon estimated useful lives ranging from 3 to 30 years. Financial instruments and hedging activities — In our natural gas marketing segment, we previously designated most of the natural gas inventory held by this operating segment as the hedged item in a fair-value hedge. This inventory was marked to market at the end of each month based on the Gas Daily index, with changes in fair value recognized as unrealized gains or losses in purchased gas cost, which is reflected in income from discontinued operations in the period of change. The financial instruments associated with this natural gas inventory were designated as fair-value hedges and were marked to market each month based upon the NYMEX price with changes in fair value recognized as unrealized gains or losses in purchased gas cost in the period of change. We elected to exclude this spot/forward differential for purposes of assessing the effectiveness of these fair-value hedges. Additionally, we previously elected to treat fixed-price forward contracts used in our natural gas marketing segment to deliver natural gas as normal purchases and normal sales. As such, these deliveries were recorded on an accrual basis in accordance with our revenue recognition policy. Financial instruments used to mitigate the commodity price risk associated with these contracts were designated as cash flow hedges of anticipated purchases and sales at indexed prices. Accordingly, unrealized gains and losses on these open financial instruments were recorded as a component of accumulated other comprehensive income, and were recognized in earnings as a component of purchased gas cost which is reflected in income from discontinued operations when the hedged volumes were sold. Gains and losses from hedge ineffectiveness were recognized in the statement of comprehensive income. Fair value and cash flow hedge ineffectiveness arising from natural gas market price differences between the locations of the hedged inventory and the delivery location specified in the financial instruments is referred to as basis ineffectiveness. Ineffectiveness arising from changes in the fair value of the fair value hedges due to changes in the difference between the spot price and the futures price, as well as the difference between the timing of the settlement of the futures and the valuation of the underlying physical commodity is referred to as timing ineffectiveness. Hedge ineffectiveness, to the extent incurred, is reported as a component of purchased gas cost reflected in income from discontinued operations for the year ended September 30, 2017. Our natural gas marketing segment also utilized master netting agreements with significant counterparties that allow us to offset gains and losses arising from financial instruments that would be settled in cash with gains and losses arising from financial instruments that could be settled with the physical commodity. Assets and liabilities from risk management activities, as well as accounts receivable and payable, reflect the master netting agreements in place. Additionally, the accounting guidance for master netting arrangements requires us to include the fair value of cash collateral or the obligation to return cash in the amounts that have been netted under master netting agreements used to offset gains and losses arising from financial instruments. Fair Value Measurements — Our discontinued operations used the same fair value measurement policies as described in Note 2 for our continuing operations. Level 1 measurements included primarily exchange-traded financial instruments and gas stored underground that was been designated as the hedged item in a fair value hedge. Within our natural gas marketing operations, we utilized a mid-market pricing convention (the mid-point between the bid and ask prices), as permitted under current accounting standards. Values derived from these sources reflected the market in which transactions involving these financial instruments are executed. Level 2 measurements primarily consisted of non-exchange-traded financial instruments, such as over-the-counter options and swaps. Short-term Debt Related to Discontinued Operations AEM had one uncommitted $25 million 364-day bilateral credit facility that was scheduled to expire on July 31, 2017 and one committed $15 million 364-day bilateral credit facility that was scheduled to expire on September 30, 2017. In connection with the sale of AEM, both facilities were terminated on January 3, 2017. Commodity Risk Management Activities Our discontinued natural gas marketing segment was exposed to risks associated with changes in the market price of natural gas through the purchase, sale and delivery of natural gas to its customers at competitive prices. Through December 31, 2016, we managed our exposure to such risks through a combination of physical storage and financial instruments, including futures, over-the-counter and exchange-traded options and swap contracts with counterparties. Effective January 1, 2017, as a result of the sale of AEM, these activities were discontinued. Due to the sale of AEM, we determined that the cash flows associated with our natural gas marketing commodity cash flow hedges were no longer probable of occurring; therefore, we discontinued hedge accounting as of December 31, 2016. As a result, we reclassified the gain in accumulated other comprehensive income associated with the commodity contracts into earnings as a reduction of purchased gas cost and recognized a pre-tax gain of $10.6 million, which is included in income from discontinued operations on the consolidated statement of comprehensive income for the year ended September 30, 2017. The Company's other risk management activities are discussed in Note 14. Impact of Financial Instruments on the Statement of Comprehensive Income Hedge ineffectiveness for our natural gas marketing segment was recorded as a component of purchased gas cost, which is included in discontinued operations on the consolidated statement of comprehensive income, and primarily results from differences in the location and timing of the derivative instrument and the hedged item. For the years ended September 30, 2017, we recognized a gain arising from fair value and cash flow hedge ineffectiveness of $3.4 million. Additional information regarding ineffectiveness recognized in the statement of comprehensive income is included in the tables below. Fair Value Hedges The impact of our natural gas marketing segment commodity contracts designated as fair value hedges and the related hedged item on the results of discontinued operations on our consolidated statement of comprehensive income for the year ended September 30, 2017 is presented below.
Basis ineffectiveness arises from natural gas market price differences between the locations of the hedged inventory and the delivery location specified in the hedge instruments. Timing ineffectiveness arises due to changes in the difference between the spot price and the futures price, as well as the difference between the timing of the settlement of the futures and the valuation of the underlying physical commodity. As the commodity contract nears the settlement date, spot-to-forward price differences should converge, which should reduce or eliminate the impact of this ineffectiveness on purchased gas cost. Cash Flow Hedges The impact of our natural gas marketing segment cash flow hedges on our consolidated statement of comprehensive income for the year ended September 30, 2017 is presented below. Note that this presentation does not reflect the financial impact arising from the hedged physical transactions. Therefore, this presentation is not indicative of the economic margin we realized when the underlying physical and financial transactions were settled.
Financial Instruments Not Designated as Hedges The impact of financial instruments that have not been designated as hedges on our consolidated statement of comprehensive income for the year ended September 30, 2017 was a decrease in purchased gas cost reflected in income from discontinued operations of $6.8 million, which is included in discontinued operations on the consolidated statements of comprehensive income. Note that this presentation does not reflect the expected gains or losses arising from the underlying physical transactions associated with these financial instruments. Therefore, this presentation is not indicative of the economic margin we realized when the underlying physical and financial transactions were settled.
