Having achieved 1% rebased revenue growth and 5% rebased Adjusted EBITDA growth for the first nine months of 2017, we remain on track to deliver on our full year 2017 outlook post the SFR BeLux acquisition, including our medium-term commitment to deliver 5-7% Adjusted EBITDA growth over the 2015-2018 period.
As in the first half of the year, our rebased revenue growth in the second half of 2017 will continue to be affected by certain regulatory headwinds as we communicated in February this year. At the same time, our mobile business will continue to be impacted by (i) lower out-of-bundle revenue, (ii) structural challenges in the prepaid segment, including the effects of the prepaid registration, (iii) lower interconnection revenue (including roaming) and (iv) lower revenue generated from handset sales. These headwinds will be broadly offset by continued solid growth in our cable subscription and B2B revenue with an increased contribution from our wholesale business driven by the Full MVNO Agreement with Lycamobile.
Having achieved 5% rebased Adjusted EBITDA growth over the first nine months of 2017, we remain on track to achieve mid-single-digit rebased growth for the full year of 2017 despite the fact that Q4 generally delivers the lowest margin contribution in our fiscal year due to end-of-year promotions and the intensely competitive environment.
In the first nine months of 2017, our accrued capital expenditures, excluding the recognition of the Belgian football broadcasting rights, represented around 23% of our revenue. Within the mix of our accrued capital expenditures, we saw a greater proportion of network-related investments on the back of the ongoing upgrade to both our fixed and mobile infrastructures. Moreover, we have also started to invest in the acquired SFR BeLux network to improve the overall customer experience including the start of the "Grote Netwerf" program in Brussels.
Finally, we delivered €345.4 million of Adjusted Free Cash Flow for the first nine months of 2017 with a particular robust performance in Q3 2017 driven by (i) solid growth in our Adjusted EBITDA, (ii) lower cash interest expenses, (iii) the accretive impact from our vendor financing platform and (iv) an improved trend in our working capital. Despite the fact that Q4 generally represents a modest Adjusted Free Cash Flow quarter, we see our Adjusted Free Cash Flow for the full year 2017 at the upper end of our €350.0 - 375.0 million range.
