Current question:
and what was this percentage change from 2007 to 2008?

Dialogue history:
[Turn 1] what percentage did the change in the proportional free cash flow from 2008 to 2009 represent in relation to that cash in 2008?
[Turn 2] and what was this percentage change from 2007 to 2008?

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 .
calculation of proportional free cash flow ( in millions ) 2015 2014 2013 2015/2014change 2014/2013 change .

Table:
calculation of proportional free cash flow ( in millions )	2015	2014	2013	2015/2014 change	2014/2013 change
net cash provided by operating activities	$ 2134	$ 1791	$ 2715	$ 343	$ -924 ( 924 )
add : capital expenditures related to service concession assets ( 1 )	165	2014	2014	165	2014
adjusted operating cash flow	2299	1791	2715	508	-924 ( 924 )

proportional adjusted operating cash flow	1741	1432	1881	309	-449 ( 449 )
less : proportional maintenance capital expenditures net of reinsurance proceeds ( 2 )	-449 ( 449 )	-485 ( 485 )	-535 ( 535 )	36	50
less : proportional non-recoverable environmental capital expenditures ( 2 ) ( 4 )	-51 ( 51 )	-56 ( 56 )	-75 ( 75 )	5	19
proportional free cash flow	$ 1241	$ 891	$ 1271	$ 350	$ -380 ( 380 )

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 .
( 4 ) excludes ipl's proportional recoverable environmental capital expenditures of $ 205 million , $ 163 million and $ 110 million for the years december 31 , 2015 , 2014 and 2013 , respectively. .

crude oil prices rose sharply through the first half of 2008 as a result of strong global demand , a declining dollar , ongoing concerns about supplies of crude oil , and geopolitical risk .
later in 2008 , crude oil prices sharply declined as the u.s .

our domestic crude oil production is about 62 percent sour , which means that it contains more sulfur than light sweet wti does .
sour crude oil also tends to be heavier than light sweet crude oil and sells at a discount to light sweet crude oil because of higher refining costs and lower refined product values .
our international crude oil production is relatively sweet and is generally sold in relation to the dated brent crude benchmark .

[Turn 1] between the years of 2008 and 2009, what was the change in the rental expense?

Pre-table text:
the future minimum lease commitments under these leases at december 31 , 2010 are as follows ( in thousands ) : years ending december 31: .

Table:
2011	$ 62465
2012	54236
2013	47860
2014	37660
2015	28622
thereafter	79800
future minimum lease payments	$ 310643

Post-table text:
rental expense for operating leases was approximately $ 66.9 million , $ 57.2 million and $ 49.0 million during the years ended december 31 , 2010 , 2009 and 2008 , respectively .
in connection with the acquisitions of several businesses , we entered into agreements with several sellers of those businesses , some of whom became stockholders as a result of those acquisitions , for the lease of certain properties used in our operations .
typical lease terms under these agreements include an initial term of five years , with three to five five-year renewal options and purchase options at various times throughout the lease periods .
we also maintain the right of first refusal concerning the sale of the leased property .
lease payments to an employee who became an officer of the company after the acquisition of his business were approximately $ 1.0 million , $ 0.9 million and $ 0.9 million during each of the years ended december 31 , 2010 , 2009 and 2008 , respectively .
we guarantee the residual values of the majority of our truck and equipment operating leases .
the residual values decline over the lease terms to a defined percentage of original cost .
in the event the lessor does not realize the residual value when a piece of equipment is sold , we would be responsible for a portion of the shortfall .
similarly , if the lessor realizes more than the residual value when a piece of equipment is sold , we would be paid the amount realized over the residual value .
had we terminated all of our operating leases subject to these guarantees at december 31 , 2010 , the guaranteed residual value would have totaled approximately $ 31.4 million .
we have not recorded a liability for the guaranteed residual value of equipment under operating leases as the recovery on disposition of the equipment under the leases is expected to approximate the guaranteed residual value .
litigation and related contingencies in december 2005 and may 2008 , ford global technologies , llc filed complaints with the international trade commission against us and others alleging that certain aftermarket parts imported into the u.s .
infringed on ford design patents .
the parties settled these matters in april 2009 pursuant to a settlement arrangement that expires in september 2011 .
pursuant to the settlement , we ( and our designees ) became the sole distributor in the u.s .
of aftermarket automotive parts that correspond to ford collision parts that are covered by a u.s .
design patent .
we have paid ford an upfront fee for these rights and will pay a royalty for each such part we sell .
the amortization of the upfront fee and the royalty expenses are reflected in cost of goods sold on the accompanying consolidated statements of income .
we also have certain other contingencies resulting from litigation , claims and other commitments and are subject to a variety of environmental and pollution control laws and regulations incident to the ordinary course of business .
we currently expect that the resolution of such contingencies will not materially affect our financial position , results of operations or cash flows. .
