Good morning, and welcome to the Spire Second Quarter Fiscal Year 2023 Earnings Conference Call. Alpine. (Operator Instructions) Please also note, this event is being recorded. I would now like to turn the conference over to Scott Dudley, Head of Investor Relations. Please go ahead.
Scott W. Dudley - MD of IR
Good morning, everyone, and welcome to our fiscal 2023 second quarter earnings call. We issued an earnings news release this morning, and you may access it on our website at spireenergy.com under Newsroom. There's also a slide presentation that accompanies our webcast, and you may download that either from our website or from the webcast site. On our site, you'll find it under Investors and then Events and Presentations.
Before we begin, let me cover our safe harbor statement and use of non-GAAP earnings measures. Today's call, including responses to questions, may contain forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Although our forward-looking statements are based on reasonable assumptions, there are various uncertainties and risk factors that may cause future performance or results to be different than those anticipated. These risks and uncertainties are outlined in our quarterly and annual filings with the SEC.
In our comments, we will be discussing net economic earnings and contribution margin, which are both non-GAAP measures used by management when evaluating our performance and results of operations. Explanations and reconciliations of these measures to their GAAP counterparts are contained in both our news release and the slide presentation. On the call today is Suzanne Sitherwood, President and CEO; Steve Lindsey, Executive Vice President and Chief Operating Officer; and Steve Rasche, Executive Vice President and CFO. Also in the room today are Scott Carter, President of Spire Missouri; and Adam Woodard, Vice President and Treasurer and CFO of our gas reserves. With that, I'll turn the call over to Suzanne.
Suzanne Sitherwood - President, CEO & Director
Thank you, Scott, and good morning, everyone. It's a pleasure, once again, to provide our quarterly update on Spire's performance, recent developments and our outlook. First, I'd like to begin with reflections on my plan to retire as President and CEO of Spire at the end of this calendar year. I have to say that leading Spire for the past 12 years has been the privilege of a lifetime and for ever grateful for the opportunity to lead the Laclede Group starting in 2011 and begin what would become a decade of growth. I'm proud to say that as a team, we successfully transformed our company into an industry leader.
We started by establishing our company mission and culture, foundation that keeps us centered, strong. This foundation allows us to develop our growth strategy that ultimately increased the scale of our utility business by investing in organic growth and expanding our portfolio of gas-related businesses. As you know, Spire now includes successful gas utility companies in Alabama, Mississippi and Missouri along with expanding midstream businesses. As our second quarter results demonstrate having a diverse portfolio of natural gas businesses and different geography enhances our ability to consistently create value.
All in all, over the past decade, we grew the company through acquisitions and expansions, ultimately increasing Spire's enterprise value more than sixfold, and we continue to be diligent in executing our strategy and in bringing value to our shareholders, customers and communities. We've done this all this while staying focused on the safety and reliability of our systems, using emissions, advancing innovation to better serve our customers and investing in our employees who are the heart full of our company. For me personally, my retirement represents the culmination of a wonderful career and more than 40 years in the natural gas industry. As you know, based on decades of experience and a global perspective, I believe that natural gas is a vital part of America's energy future, and I'm energized to continue leading Spire through December and continue to represent Spire and our national industry as the Chair of the American Gas Association.
In terms of what's next for fire, our Board has initiated a thorough and comprehensive search, including internal and external candidates. And it include those who will build upon our culture and positions pyrotinued long-term growth and success. Spire is a strong and well-positioned company, a proven growth strategy. We have confidence in that strategy and in the ability of our experienced management team and employees to successfully execute on our plans well to the future. Now I'll pass the call to Steve Lindsey.
Steven L. Lindsey - Executive VP & COO
Thank you, Suzanne. I want to begin by acknowledging the outstanding work of our employees and continue their focus on maintaining safe and reliable gas delivery operations and excellent service to our customers. Your efforts and dedication are especially important and greatly appreciated during the winter heating season. Let me start with an update on capital investment. First half of fiscal 2023, Spire total CapEx was $308 million, 95% going toward our gas utilities. For over a year, our utility spend increased 9% with more than $200 million going towards upgrading our distribution pipeline infrastructure and to connect more homes and businesses to safe, reliable and affordable natural gas service.
Based on our spend for the first half of the year, we reaffirm our FY '23 capital investment target of $700 million. Our expected CapEx over the next 10 years remains $7 billion, with a focus on investment in our infrastructure to support system safety and liability, customer additions that drive growth and in innovation and technology, enhance customer service and experience, including advanced meters. We have upgraded 375,000 meters across our footprint since we began the program. Turning to the performance of our gas utilities in the second quarter. First and foremost, we delivered for our customers, we continued solid operating performance as we work toward our targets on key metrics for the year.
Our Gas Utilities also delivered improved earnings and cash flow as new rates went into effect both Missouri, Alabama around the end of last calendar year, offset combined headwinds of warm weather and higher costs. We experienced a very warm winter across our gas utilities, which resulted in lower volumes and that impacted margins. Hemertures were approximately 21% warmer than normal and last year. While we do have weather mitigation in our rate designs and largely work in Missouri was much less effective in Alabama experienced one of the warmest winters on record. In fact, temperatures were 26% more than normal for Spire Alabama and 12% warmer than last year. Weather mitigation mechanism uses actual degree days compared to a normal Orlidoes not capture all the usage variation from weather, especially during very warm periods. Reminder that weather mitigation also does not cover commercial and industrial customer usage, so we had some exposure there as well.
Last quarter, we discussed the higher interest in O&M expenses, so let me provide an update on these costs. Interest costs increased in the second quarter, reflecting higher short-term rates combined with higher balances. In fact, short-term rates averaged more than 5% last quarter, up over 450 basis points in the second quarter of last year. Gearing the short-term debt balances carrying are tied to gas costs. We expect to recover current gas costs by the end of the calendar year, and we made progress towards this goal last quarter. On the cost side, we continue to control our O&M expenses to help offset the headwind we experienced in margins. We believe that moderating O&M increases and fully recovering our working capital balances will enable our utility financial performance to further improve fiscal 2020.
Let me provide one additional update on our utilities. So last quarter, Inspire Missouri filed for recovery of system upgrade investments for the October to February period. Missouri Public Service Commission approved $7.7 million in new ISRS revenues effective May 6, 2023. Now let me provide a quick update on our midstream segment. First half of the year, we invested $17 million, reflecting the spend in the first quarter expansion of Spire Storage. Preparations are underway this month to resume construction as spring begins in Wyoming. The project remains on schedule and on budget. I would note that there's already been strong commercial interest in the first phase of this additional capacity is speaks to the increasing demand and market value of storage services. also recently acquired Salt Plains, a small storage facility in Northern Oklahoma, 10 Bcf of working gas capacity. Facility is valuable. In addition to our midstream portfolio, we expect these operations to be accretive to net economic earnings.
Next month, Spire will publish its fifth annual report on sustainability, reflecting continued progress in measuring our performance and impact as we work to become even more sustainable. Let me cover a few highlights for calendar 2022, starting with protecting the environment. The top chart on this slide shows, based on our initial assessment, 2022, our gas utilities achieved a 50% reduction in methane emissions since 2005 and a 4 percentage point improvement over 2021. This reflects the cumulative investments that we made to upgrade our distribution network, focus on lead productions. The metric we track regarding methane emissions reduction leaks per 1,000 system miles.
Please note that in fiscal 2022, we saw another significant reduction. Our sustainability efforts also focus on how we care for people. This includes further strengthening our safety culture for the benefit of our employees and those they serve. Spire safety, as measured by the OSHA DART rate continued to improve in fiscal 2022 with the rate of employee injuries decreasing 55% since 2018. Over the year, Spire has built a reputation for having a strong corporate government -- governance, which helps us enhance last year with our Board assuming oversight for sustainability efforts and disclosures. With that, I'll turn it over to Steve Rasche for a financial review and update. Steve?
Steven P. Rasche - Executive VP & CFO
Thanks, Steve. Good morning, everyone, and thank you for joining us today. For our fiscal second quarter, we reported net economic earnings of $199 million, a 10% increase from last year, driven by improved results from all our businesses, offset in part by higher corporate costing. Economic earnings per share of $3.70 were 8% above last year. Walk through the segments. Gas Utility had earnings of $184 million, nearly 9% ahead of last year. As Steve just mentioned, we saw growth from new rates in Missouri and Alabama, which more than offset the headwinds of lower usage and higher interest expenses.
Gas marketing was well positioned to take advantage of market conditions to optimize the storage and transportation positions this quarter, posting earnings of nearly $22 million, up 50% last year. Similarly, our Midstream earnings were ahead of last year as storage was able to optimize its operations and withdraw commitments. As I just mentioned, corporate costs were higher, primarily due to higher interest expense, a portion of which was incurred to finance our non-utility businesses. Slide 9 provides an overview of key variances for the quarter. We've already touched on contribution margin drivers. So here are a couple of other highlights. Gas Utility O&M expenses were up net of pension reclassification by $12 million due to, first, the roughly $6 million in Missouri overhead costs deferred in the prior year but expense this year. Secondly, higher bad debt expenses, $3 million, reflecting principally higher commodity costs. And lastly, higher nonemployee costs, especially third-party contractor expenses as we continue to focus on high customer service levels.
Overall, gas utility O&M cost net of bad debts and Missouri overhead treatment, are expected to trend a bit lower than our 4% inflation marker as we focus on opportunities to control costs for the rest of our fiscal quarter. Spire marketing costs were also higher, representing mostly costs driven by higher margins. And other income was a turnaround from last year, up $8 million after reclassification, driven by unrealized investment returns as well as interest carrying cost credits. We'll take a closer look at our liquidity and interest expense. We have made substantial progress in paying down our short-term debt with the quarter end balances down $665 million from December 31.
This has been one of our focus areas, and we achieved this reduction through a combination of: first, improved operating cash flow, including reduction in deferred gas cost balances. Second, terming out some of our debt needs, including $400 million in Missouri mortgage bonds, essentially advanced funding our pending $250 million maturity later this year and $150 million holding company private placement, remembering that we had a $25 million maturity that we paid off last December. I would note that both offerings were at net interest rates below current short-term rates due to our favorable hedging position coming into the year. I would also note that in April, we paid down $150 million of our term loan, and we anticipate retiring the remaining balance later this quarter.
Looking forward, our interest rate -- our interest expense run rate at the utilities will continue to decline as we collect gas costs in the balance of this calendar year. As a reminder, we do get recovery on most of the utility interest expense, either in rates in Alabama or through the Missouri carry cost credits I just noted in other income. From a holding company standpoint, financing plan I just outlined supports our marketing and midstream businesses and the planned matures at the Spire Inc. level in 2024.
Now turning to our outlook. We remain confident in our long-term net economic earnings per share growth target of 5% to 7%, starting from the midpoint of our initial fiscal year '23 guidance. Our growth is driven by utility rate base investments. And as Steve mentioned, we also reaffirm both our current year, our 10-year CapEx targets. We have narrowed our '23 net economic earnings guidance range to $4.20 to $4.30 per share. As Suzanne mentioned, the benefit of a portfolio of natural gas businesses is the opportunity to create value and offset headwinds across our platform. So while the midpoint of our range remains the same, how we're getting there has shifted a bit due in large part to the results from Winter. Going by segment, we are lowering our gas utility range to reflect the headwinds we discussed earlier, offset in part by cost discipline and a lower effective tax rate, reflecting principally earnings mix and the timing of tax credits.
We've raised the ranges for both gas marketing and midstream due to strong year-to-date results. Corporate costs moved up $5 million to reflect principally higher holding company interest costs. And a couple of quick observations on financing. With new rates and a clear path of recovery of utility gas costs, we expect continued cash flow growth, supportive of our FFO to debt target of 15% to 16%. We've also updated our long-term financing forecast to reflect actual capital issued this year as well as reduced equity needs overall as a result of recycling the strong earnings from this market.
So in summary, we're on track with this year's plans, perhaps in a little bit different way than we had anticipated 6 months ago. We've pivoted to ensure that we offset the headwinds this year and are well positioned to rebound in 2024 and beyond. With that, let me turn it back over to you, Suzanne.
Suzanne Sitherwood - President, CEO & Director
Thank you, Steve and Steve. And in closing, we're well positioned to continue growing and delivering stronger overall performance for our customers, communities and investors. We look forward to seeing many of you at the upcoming AGA Financial Forum in a few weeks. So then thank you for your continued interest and investment in Spire. We're now ready to take your questions.
Operator
(Operator Instructions) And the first question will be from David Arcaro from Morgan Stanley.
David Keith Arcaro - Executive Director & Lead Analyst of Utilities
Suzanne, congratulations on the upcoming retirement.
Suzanne Sitherwood - President, CEO & Director
Thank you very much, David. Appreciate it.
David Keith Arcaro - Executive Director & Lead Analyst of Utilities
Maybe starting there on the CEO search process. Could you give just a sense of what the timing would be for a potential decision when you would anticipate concluding that? And any thoughts on just the likelihood of an internal versus an external candidate?
Suzanne Sitherwood - President, CEO & Director
I guess, as you know, the announcement was clear that I retired at the end of the year, and the Board has started a process, but I certainly don't want to get over my sees in terms of the timing of all that, but work the process in a very methodical way. They obviously know the vision and strategy of the company, and they'll be consistent in their search for what is best for the company. So again, I don't want to get ahead of them, but just know that I'm retiring at the end of the year.
David Keith Arcaro - Executive Director & Lead Analyst of Utilities
Got it. That makes sense. And then also just curious at a higher level, there have been media articles about several gas utilities potentially coming to the market. I was just wondering what your latest thoughts are on M&A and consolidation more strategically?
Suzanne Sitherwood - President, CEO & Director
I guess it's great that there's so much interest in, I guess, I would say gas assets, but I hate to be the person this morning to say we're not commenting. But as you all know that are on the call, we don't comment on these types of activities in the market. But from somebody who's been in the industry for 42 years, it's always great to see ebbs and flows across those decades. I see a lot of change in this industry from consolidation to deployment of technology to sustainability. And I think it's very healthy for our industry to have these changes in decades by after 42 years, I have the ability to reflect. And I think that's the use that again, we don't comment directly on these types of activities.
David Keith Arcaro - Executive Director & Lead Analyst of Utilities
Yes. Understood. And then maybe one more on the full year guide, Economic earnings was down $15 million or so at the Gas Utility segment. I was wondering how much of an impact was the lower margin at the gas utilities during the winter versus the prior guidance expectation? And then how much was an incremental interest expense drag?
Steven L. Lindsey - Executive VP & COO
David, this is Steve. I'll take a shot at that. We had a fairly full view the interest rate and interest cost exposure coming into the quarter. So I don't think it was much of a surprise, although with the warmer winter, there's always a little bit less pull-through in terms of paying down deferred gas costs so the balances are riding a little bit higher than we had expected. So I would put that as a secondary consideration. It's really the margins, and as Steve mentioned in the prepared remarks, it's really the margins down in Alabama. And both of our utilities are large utilities. We earned a majority of our earnings during the winter heating season and weather mitigation is designed to offset that. And in Missouri, it largely worked in Alabama because of the way in which the weather pulled through it did not. So that was the primary driver behind the rerate that you saw on the utility range.
But again, we've got plans in place to offset that weather always reverts back to normal and still in a good spot from a cost standpoint. So I think we're positioned well as we head into '24 and beyond. But the only part I would add to that is, as I've mentioned, is that even with weather mitigation, that does not apply to commercial and industrial market. So when you have winter, it not only affects the residential, but also the others.
Operator
And our next question is from Richard Sunderland from JPMorgan.
Richard Wallace Sunderland - Associate
Circling back on that last question, the O&M, I guess really what's, let's say, the 23 efforts and how you frame that for '24. Could you parse that a little bit more in terms of what you're focusing on? And how much of that is in reaction to the weather headwinds this year versus longer-term efforts really targeted around 24 performance?
Steven L. Lindsey - Executive VP & COO
Well, I can take the second part because you know we have a long history of investing in technology process improvement, et cetera, to offset normal inflation and create headroom in our customer bill because we also acknowledge that we're investing in rate base growth, and we want to be always cognizant of the impact on our customer build. All of those macro plans continue at pace. We've actually looked to push the accelerator or a few of those given the warmer weather. In the longer term, that's always our goal is to offset as much of that discretionary cost if you want to use that term as we can just because we want to make sure that we're being clear with the customer.
In terms of this year, we are continuing to look in every place that we possibly can to upset cost. And that isn't unusual that across the space, as the winter started to unfold, it's been record warm in many areas, including Alabama for us.
Suzanne Sitherwood - President, CEO & Director
To your point, Steve, when the weather is warmer, it gives the operational teams more opportunity to look at some of those efficiencies versus when it's unusually cold weather, the way that Steve Lindsey and the team operate the company out of those conditions is different. And like you said, it's sort of a natural hedge there, if you will here company.
Steven P. Rasche - Executive VP & CFO
And the last piece I'll add is a little bit following up on Steve's comments, we are on common platforms across all of our companies right now, which will allow us to really start to leverage some standardization around workload planning around supply chain, around logistics. So I think we're in a good situation now as we move forward to really drive some strong cost management throughout all of our companies.
Richard Wallace Sunderland - Associate
Okay. Got it. That's helpful color there. Salt Plains, the $37 million investment. Could you outline a little bit more about what's attractive there, how you think about that asset relative to the Spire Storage expansion efforts? And is this indicative of a platform you're looking to grow even further through additional acquisitions?
Steven L. Lindsey - Executive VP & COO
I'll start. As we mentioned, it's a very small asset, but we think it is well positioned, and we think it's going to help some of our other gas businesses in terms of what they can do going forward. I don't think it's directly connected at all with Spire Storage West. They're independent facilities. Relative to the platform, I think as Suzanne Steve and even myself have mentioned, we think having diverse gas businesses, as evidenced this year, create a little bit of a natural hedging effect. So again, I don't know that I would necessarily say it's a platform enabler, but we looked at that opportunity as being something that, at least from our business perspective, made a lot of sense in the near term. And we do expect it to be accretive going forward.
Richard Wallace Sunderland - Associate
Okay. Got it. And is there any further investment with Salt Plains, particularly that you're anticipating at this point?
Steven L. Lindsey - Executive VP & COO
At this point, no, again, we're looking to go in and take advantage of some early opportunities in terms of the way it's being operated and again, looking for some leverage opportunities with our other businesses.
Steven P. Rasche - Executive VP & CFO
And Richard, I would add that put our Spire Storage facility in the same position in 2025. Once we invest the capital, this becomes much more utility-like in terms of dealing with customers. In fact, many of the customers are utilities and pipelines and folks who serve those. And they're on contracts that range in the industry for 3 to 5 years, and this facility is no different. So since we're buying an existing operating facility without a lot of CapEx needs for expansion, it really is just plugging it in and giving our midstream team the opportunity to optimize the operations in that facility just like they are and will as far store-wise.
Operator
And the next question will be from Shahriar Pourreza from Guggenheim.
Shahriar Pourreza - MD and Head of North American Power
Just a quick one on just inflation in O&M. Just I guess about half of your O&M increase in the quarter came from the overhead costs, which you were, of course, deferring last year, which is separate from just inflation in general. I guess, how should we think about the $6 million on a go-forward basis? Any sort of special considerations? Or should we just treat it the same as all the O&M going forward?
Steven P. Rasche - Executive VP & CFO
It's really cost that we'd already incurred that shifted back into -- its shifted into O&M. So you kind of take that out of the inflation calculus for what it's worth.
Shahriar Pourreza - MD and Head of North American Power
Okay. Perfect. That's helpful. And just real quick lastly is just on the higher interest cost, corporate drag was nearly $5 million in the quarter year-over-year. Obviously, you guys have been very clear about your planned equity issuances, you've done mortgage bonds, you've manage short-term debt needs really well, done some private placements. But any thoughts around sort of the cash pay convert market that's formed, could you still see a benefit there?
Adam W. Woodard - Treasurer
Yes, Shahriar. This is Adam. We're always... Yes, we're always interested in different interesting financing techniques. I wouldn't say there's anything on the horizon there, but it's certainly an interesting trend that we've seen here so far this year.
Steven L. Lindsey - Executive VP & COO
Yes. And Shahriar, as you know, there's been a flurry of activity, including this week, and we do watch that closely. We perhaps through our benefit and the credit of Adam and the team, we entered this year at an extremely strong hedge position from an interest rate perspective. So we all understand those in the industry that a convert actually does buy down the current interest rate versus just doing straight debt. I think we got every bit of that benefit, but we did it in the hedge market in prior periods. So we were taking advantage of that this year. So the convert wasn't really as attractive for us, given that we already had a built-in advantage that we wanted to take advantage of.
Shahriar Pourreza - MD and Head of North American Power
Perfect. I appreciate it. And congrats on Phase 2. Appreciate it, guys.
Operator
And the next question is from Paul Zimbardo from Bank of America.
Paul Andrew Zimbardo - VP in Equity Research & Research Analyst
Can you hear me? Look, I suppose a couple of questions here. First off, just coming back to the guidance this year, obviously, reracking things it's had in the composition. Just looking forward to '24 year and some of the knock-on effects you guys coming off confident and kind of getting trued up here, but -- and specifically also reaffirming the 5% to 7% off 23%. Can you talk about maybe some of the puts and takes as you look forward in terms of some of the pressures that you experienced right now?
Steven P. Rasche - Executive VP & CFO
Yes. And Julien, this is Steve. We talked about a lot of those in our prepared remarks in terms of getting back on top of interest rates and especially on the deferred gas balances, which is a phenomenon that we and many of the industry are dealing with, and I think we have a clear line of sight to doing that. We continue to manage O&M cost, as we mentioned a bit earlier. So I think that's another one of the places where I think we're very confident as we go into next year. And the beauty of where we stand right now is that we're not in any regulatory proceedings within our gas utilities. So we don't need a go-get. There's no rate change that's built into our thoughts as we think about '24 because we have nothing on the horizon at this juncture. So those would be some of the clear things in my mind that position us well. And the capital markets activity that we completed this quarter in many ways actually takes some of the interest rate risk off the table going forward.
Steven L. Lindsey - Executive VP & COO
Yes. No, I think we're relatively defensively postured on interest rates going forward from here. Bringing those balances down is certainly key. I think that's no different than most of our peers as well. And so we feel pretty good about that 5% to 7% on a go-forward basis.
Paul Andrew Zimbardo - VP in Equity Research & Research Analyst
Right. So maybe more specifically here, with respect to the O&M, you feel like that's pretty much entirely offset. And when you think about the composition, '23 might have shifted a little bit the '24 composition, if you think about it that way, you're able to get a lot of the OM such that we should in the typical earned ROE trends that we've seen in the utilities?
Steven P. Rasche - Executive VP & CFO
You broke up a little bit there at the end. But yes, I mean, we feel like we've really -- we definitely are focused on O&M and the pull-through there and as we kind of guided in that 4% range coming in, we're -- I think we have seen the ability to get after that. We have a historical ability to get after that as well and feel good about saying going into next year.
Paul Andrew Zimbardo - VP in Equity Research & Research Analyst
Got it. Excellent. And then just coming back to the balance sheet side of the equation super quickly. I noticed the Alabama point yesterday from Moody's here. Can you talk a little bit more about just your commentary in the prepared remarks, lease alluded to an intact metrics, and you talked about it in the slides. But can you talk a little bit about some of the plan here with respect to the subsidiary and overall financing plan?
Steven L. Lindsey - Executive VP & COO
Yes. No, thanks for noting the Moody's report. We were very pleased to have Missouri come off of a negative outlook and the affirmation of our ratings. They did, as you mentioned, I think we go to a negative outlook on Alabama. It's something that we had discussed with them before was not a surprise. But I think you could take that report also as an affirmation of what our execution on our plan and towards our targets. And it's something that we certainly stay close to both the agencies on that topic. And again, feel we continue -- I think you hear us continually restate those targets and progress towards those targets. And that does get wrapped up into our progress around our equity plans as well, which we continue with. But again, still see that pathway towards our credit metric targets and feel pretty good about it.
Operator
(Operator Instructions) The next question is from Christopher Jeffrey from Mizuho Securities.
Christopher Francis Jeffrey - Associate
Maybe just 2 quick ones on Salt Plains. Just curious as far as the funding mix, I know it's not a huge acquisition, but whether that changed from maybe your typical funding for the expansion, for example? And then also just how much that's contributing to the guidance change for the midstream business for '23?
Steven P. Rasche - Executive VP & CFO
Yes, I can take that, Christopher. We typically guide and I think it's a good benchmark that you can expect a 50-50 cap structure underneath the acquisition, and that was factored in to our updated financing guidance for this year is really the strength of Spire Marketing and the ability to recycle that capital. So that offset that headwind and then some as we look at the balance of this year. And as Adam mentioned, to stay on track to get our metrics to our targets. We do expect Salt Plains to be accretive. It's a small deal, so it does add a little bit to our accretion. But it's typically the case in the Spire world is in the stub year of acquisition. We do not include the earnings for any newly acquired entity, including any transition cost in net economic earnings and then it's fully reflected in the first full year of operations, and we'll deploy the same thought this year. So the short answer is no, it wasn't factored into the range for midstream this year, but you would fully expect it to be reflected in the update when we launched '24.
Christopher Francis Jeffrey - Associate
Great. And then maybe just more generally as far as lower natural gas prices. Just kind of wondering a time line of when and how you expect to see the benefits coming through either on working capital or bad debt expense? Or even if it could maybe shorten the time line on the deferred costs -- deferred gas costs from last year. I don't know if that's possible. But if you could kind of just speak to that.
Scott B. Carter - President & Director
This is Scott Carter. I'll take a first stab at that. But we're already seeing the benefits of that as it works through the dollar cost average our inventory and then our gas cost obviously, we're working through some of the backlog of that with our storm costs that we're recovering over years and then kind of the higher gas costs we saw last year. But it's not in our plan. We're seeing it. Obviously, we're already seeing the impacts of bringing down some of our working capital. But going forward, as we work off those balances, and again, we think we'll get most of that done this year. You'll start seeing that then translate into lower bills. So songline of sight of that, we'll assume the market holds up, we'll start being able to lower our gas cost rates to customers, and then that translates into the bad debt. So you got the complete lineage correct, and we'll see that coming through pretty strongly, we believe, as we head into next calendar.
Christopher Francis Jeffrey - Associate
Congratulations through that.

And ladies and gentlemen, this concludes our question-and-answer session. I would like to turn the conference back over to Scott Dudley for any closing remarks.
Scott W. Dudley - MD of IR
