foreign currency rates we are subject to translation and transaction risks related to changes in foreign currency exchange rates .
since we report revenues and expenses in u.s .
dollars , changes in exchange rates may either positively or negatively affect our consolidated revenues and expenses ( as expressed in u.s .
dollars ) from foreign operations .
the primary foreign currencies that impacted our results during 2015 included the australian dollar , brazilian real , british pound sterling and euro .
based on 2015 exchange rates and operating results , if the u.s .
dollar were to strengthen or weaken by 10% ( 10 % ) , we currently estimate operating income would decrease or increase approximately 4% ( 4 % ) , assuming that all currencies are impacted in the same manner and our international revenue and expenses remain constant at 2015 levels .
the functional currency of our foreign operations is generally their respective local currency .
assets and liabilities are translated at the exchange rates in effect at the balance sheet date , and revenues and expenses are translated at the average exchange rates during the period presented .
the resulting translation adjustments are recorded as a component of accumulated other comprehensive loss , net of tax , in the stockholders 2019 equity section of our consolidated balance sheets .
our foreign subsidiaries generally collect revenues and pay expenses in their functional currency , mitigating transaction risk .
however , certain subsidiaries may enter into transactions in currencies other than their functional currency .
assets and liabilities denominated in currencies other than the functional currency are susceptible to movements in foreign currency until final settlement .
currency transaction gains or losses primarily arising from transactions in currencies other than the functional currency are included in office and general expenses .
we regularly review our foreign exchange exposures that may have a material impact on our business and from time to time use foreign currency forward exchange contracts or other derivative financial instruments to hedge the effects of potential adverse fluctuations in foreign currency exchange rates arising from these exposures .
we do not enter into foreign exchange contracts or other derivatives for speculative purposes. .

Current question:
what is the proportional recoverable environmental capital expenditures in 2015?

Dialogue history:
[Turn 1] what is the proportional recoverable environmental capital expenditures in 2015?

Pre-table text:
proportional free cash flow ( a non-gaap measure ) we define proportional free cash flow as cash flows from operating activities less maintenance capital expenditures ( including non-recoverable environmental capital expenditures ) , adjusted for the estimated impact of noncontrolling interests .
the proportionate share of cash flows and related adjustments attributable to noncontrolling interests in our subsidiaries comprise the proportional adjustment factor presented in the reconciliation below .
upon the company's adoption of the accounting guidance for service concession arrangements effective january 1 , 2015 , capital expenditures related to service concession assets that would have been classified as investing activities on the consolidated statement of cash flows are now classified as operating activities .
see note 1 2014general and summary of significant accounting policies of this form 10-k for further information on the adoption of this guidance .
beginning in the quarter ended march 31 , 2015 , the company changed the definition of proportional free cash flow to exclude the cash flows for capital expenditures related to service concession assets that are now classified within net cash provided by operating activities on the consolidated statement of cash flows .
the proportional adjustment factor for these capital expenditures is presented in the reconciliation below .
we also exclude environmental capital expenditures that are expected to be recovered through regulatory , contractual or other mechanisms .
an example of recoverable environmental capital expenditures is ipl's investment in mats-related environmental upgrades that are recovered through a tracker .
see item 1 . 2014us sbu 2014ipl 2014environmental matters for details of these investments .
the gaap measure most comparable to proportional free cash flow is cash flows from operating activities .
we believe that proportional free cash flow better reflects the underlying business performance of the company , as it measures the cash generated by the business , after the funding of maintenance capital expenditures , that may be available for investing or repaying debt or other purposes .
factors in this determination include the impact of noncontrolling interests , where aes consolidates the results of a subsidiary that is not wholly-owned by the company .
the presentation of free cash flow has material limitations .
proportional free cash flow should not be construed as an alternative to cash from operating activities , which is determined in accordance with gaap .
proportional free cash flow does not represent our cash flow available for discretionary payments because it excludes certain payments that are required or to which we have committed , such as debt service requirements and dividend payments .
our definition of proportional free cash flow may not be comparable to similarly titled measures presented by other companies .

Post-table text:
( 1 ) service concession asset expenditures excluded from proportional free cash flow non-gaap metric .
( 2 ) the proportional adjustment factor , proportional maintenance capital expenditures ( net of reinsurance proceeds ) and proportional non-recoverable environmental capital expenditures are calculated by multiplying the percentage owned by noncontrolling interests for each entity by its corresponding consolidated cash flow metric and are totaled to the resulting figures .
for example , parent company a owns 20% ( 20 % ) of subsidiary company b , a consolidated subsidiary .
thus , subsidiary company b has an 80% ( 80 % ) noncontrolling interest .
assuming a consolidated net cash flow from operating activities of $ 100 from subsidiary b , the proportional adjustment factor for subsidiary b would equal $ 80 ( or $ 100 x 80% ( 80 % ) ) .
the company calculates the proportional adjustment factor for each consolidated business in this manner and then sums these amounts to determine the total proportional adjustment factor used in the reconciliation .
the proportional adjustment factor may differ from the proportion of income attributable to noncontrolling interests as a result of ( a ) non-cash items which impact income but not cash and ( b ) aes' ownership interest in the subsidiary where such items occur .
( 3 ) includes proportional adjustment amount for service concession asset expenditures of $ 84 million for the year ended december 31 , 2015 .
the company adopted service concession accounting effective january 1 , 2015 .
