Thanks, Sam. In my remarks, I will focus on FFO. We highlight this metric because we believe it’s a good proxy for cash flow from our operations. I will also focus on AFFO yield which is equal to FFO less maintenance CapEx divided by invested capital. This is a measure of how effectively we deploy our capital.
During the quarter, our FFO was $108 million, an increase of $10 million over the prior year. However, our per unit FFO of $0.58 was $0.0.4 lower than the prior year due to the impact of our October equity issuance, which primarily funded the investment in our railroad. Cash flow from this investment will ramp up over the next 4 quarters.
Our results reflected strong performance from our Transport and energy and Utilities platforms, partially offset by lower contribution from our Timber business. Overall, we generated an AFFO yield of 10% on an invested capital base of $3.6 billion.
Our utility segment generated FFO of $65 million during the quarter compared with $61 million in the prior year. The increase was primarily driven by greater contributions from our regulated terminal and electricity transmission operations, as a result of additions to our rate base and favorable foreign exchange movements.
This was partially offset by a reduction in the contribution from our UK regulated distribution business where we had lower connection revenues compared with an exceptionally strong prior year period. For the quarter, our utility segment generated an FFO yield of 14% compared with 13% in the prior year.
During the first quarter, our transport and energy segment posted a sharp increase in cash flow with $62 million of FFO compared to $45 million in the prior year. The improvement reflects a doubling of FFO from our Australian railroad, supported by consistent results from our energy transmission and distribution and ports businesses.
Three of these 6 expansion projects at our railroad have commenced commercial operations, and we transported an incremental 1.4 million tonnes of iron ore over our network during the quarter. By the end of the second quarter, we expect that -- these 3 customers to be fully ramped-up and shipping at a rate of approximately 2.4 million tonnes per quarter.
In mid-April, steel production resumed at the Teesside Cast Products plant, which is a large customer of our UK port. Although the port’s throughput has been impacted by economic weakness in Europe, we expect EBITDA to increase by between $6 million to $8 million annually, once production at this steel facility reaches capacity.
Finally, this was the first quarter of our ownership of our Chilean toll road. Although it is early days, this investment is off to a strong start with traffic 14% above prior year levels. Overall, our transport and energy segment generated a 12% AFFO yield in the quarter compared to an 8% AFFO yield in the prior year.
Our timber segment posted FFO of $6 million for the quarter compared to $10 million in the prior year. While we continue to benefit from relatively strong export markets, our performance was impacted by reduced demand from China due to slowing growth and high inventories. For the quarter, average prices for our highest margin product, Douglas-fir, declined by 6%, and prices for whitewood declined by 11%, compared with the prior year. This was partially offset by a 6% increase in sales volume.
Our timber segment generated a 5% AFFO yield in the quarter compared to an 8% AFFO yield last year. During the second half of the year, we expect that the excess inventory will be absorbed in the Chinese market. Once improved pricing materializes, we will be in a position to increase production above our long-run sustainable yield.
On the corporate finance front, we are working on several initiatives. The most important of which is the refinancing of our North American gas transmission business. This system is a strong franchise consisting of over 15,000 kilometres of natural gas transmission lines, serving 60% of the Chicago market.
Over the past 2 years, this business has been challenged by a combination of a negative rate settlement as well as declining market fundamentals. Consequently, a decision was made to reduce leverage in this business. Together with our partners, we have agreed to inject equity to retire holding company debt, our share of which is $200 million. We are also undertaking a refinancing at the operating company.
We recently launched a tender offer to buy back the December 2012 maturity of its bonds, and we intend to refinance this debt with a combination of secured loans and bonds. In addition, a portion of the annual cash flow generated by the business will be used to retire additional debt. In time, we expect cash flow from this business will recover significantly, along with its credit profile.
We have also begun to work on a corporate debt issue of approximately $300 million to fund the equity injection into our North American gas transmission business, as well as an upcoming $120 million corporate bond maturity. In that regard, we recently engaged S&P in a rating advisory service role.
We are pleased to report that S&P has initiated coverage of Brookfield Infrastructure with an investment grade rating of BBB+, which we believe will provide us access to low cost debt capital. We expect to complete this financing in the next 2 quarters.
Finally, we continue to proactively advance a number of refinancings to take advantage of the historically low interest rate environment. We executed a NZD$155 million refinancing at our New Zealand regulated distribution company in the bank market with an average life of 4 years and an average spread of 180 basis points over the New Zealand base rate, and we are beginning to focus on a number of 2013 refinancings. We finished the quarter with $1.3 billion of liquidity across the group, including almost $700 million at the corporate level.
Now, I will turn the call back over to Sam to walk through our growth initiatives and outlook.
