Good day, ladies and gentlemen, and welcome to the Insteel Industries’ Fourth Quarter 2012 Earnings Call. [Operator Instructions] As a reminder, this call may be recorded.
Operator
I’d now like to introduce your host for today’s conference, H. O.
Woltz. Sir, you may begin.
H.O. Waltz
Thank you. Good morning and thank you for your interest in Insteel and welcome to our fourth quarter 2012 conference call, which will be conducted by Mike Gazmarian; our Vice President, CFO and Treasurer and me.
H.O. Waltz
Before we begin, let me remind you that some of the comments made in our presentation are considered to be forward-looking statements which are subject to various risks and uncertainties that could cause actual results to differ materially from those projected. These risk factors are described in our periodic filings with the SEC.
I'll now turn it over to Mike to review our fourth quarter financial results and then I will follow-up to comment more on market conditions and our business outlook.
Michael Gazmarian
Thank you, H. As we reported earlier this morning, Insteel’s net earnings for the fourth quarter ended September 29, remained relatively flat at $0.8 million compared to $0.9 million in the third quarter and $1 million in the same period a year-ago.
Michael Gazmarian
Earnings per diluted share were unchanged from both the third quarter and the prior-year at $0.05. Our fourth quarter results were unfavorably impacted by continued weakness in our construction end markets and further compression and spread similar to what we experienced during the third quarter reflecting the consumption of higher cost inventory under FIFO accounting that was purchased in earlier period, matched against declining selling prices.
Net sales for the fourth quarter were down 1.2% from the prior-year as a 5.1% reduction in average selling prices offset a 4.1% increase in shipments. On a sequential basis, net sales were up 4.6% from Q3 on a 6.8% increase in shipments partially offset by a 2.1% decrease in average selling prices.
Gross profit for the fourth quarter fell to $5.9 million from $7.7 million in the year-ago quarter with gross margins narrowing to 6% in net sales from 7.8% due to the compression in spread which more than offset the favorable impact of higher shipments and lower unit conversion costs. On a sequential basis, gross profit fell $0.5 million from Q3 and gross margins decreased 80 basis points primarily due to further compression in spread.
SG&A expense for the fourth quarter was down $1.4 million from the prior-year primarily due to the relative year-over-year changes in the cash surrender value of life insurance policies, the net gain on the proceeds from the life insurance claim and lower compensation expense. Interest expense for the fourth quarter fell to about half the prior-year level, largely due to the lower borrowing rates in our revolving credit facility relative to the $13.5 million note related to the Ivy acquisition that was outstanding in the prior-year quarter and prepaid in December.
Our effective income tax rates for the fourth quarter dropped to 27.5% from 47.9% a year-ago, primarily due to changes in permanent book versus tax differences which have an amplified impact on the rate at lower levels of pre-tax earnings. Going forward, our effective rate will continue to be subject to fluctuations based upon the level of future earnings, changes in permanent book versus tax differences and adjustments to the other assumptions and estimates entering into our tax provision calculation.
Moving to the cash flow statement and balance sheet, operating activities provided an $11.4 million of cash for the fourth quarter while using $3.2 million in the same period last year primarily due to the year-over-year changes in net working capital, largely related to the current year reduction in inventories.
Accounts receivable rose $1.4 million during the quarter due to the sequential increase in sales and inventories fell $11.6 million from Q3 on an 8.3% decrease in units and a 7.3% decline in average unit values, while accounts payable and accrued expenses fell $2.1 million primarily due to lower raw material purchases in the later part of the quarter.
Our inventory position at the end of the quarter represented a little over 3.5 months of shipments on a forward looking basis, calculated off of our forecasted Q1 shipments and reflected lower unit values than the material that was sold during the fourth quarter under FIFO accounting due to the recent decline in raw material cost.
Capital expenditures came in at $8.1 million for the year versus $7.9 million last year and are expected to total less than $12 million in fiscal 2013, which is consistent with our previous indication that CapEx would not exceed $20 million over the 2012 to 2013 period. We ended the quarter with a $11.5 million outstanding on our revolving credit facility, down $7.1 million from the end of Q3 and $67.2 million of additional borrowing availability.
As we head into fiscal 2013, the latest macro data for the construction sector reflects mixed signals. Total construction spending for August fell to its lowest level in 4 months due to weakening outlays for non-residential construction.
After showing signs of improvement earlier in the year, private non-residential construction has now fallen sequentially for 3 straight months. Public construction was down 3.5% from a year-ago due to ongoing budget pressures at the state and local level and the winding down of federal stimulus spending.
In contrast, the continued improvement in the housing sector has driven private residential construction to its highest level since January 2009. Yesterdays housing reporting for September reflected similar strength with total starts rising to the highest level in over 4 years.
Assuming these favorable trends continue, the improvement in new home construction should begin to favorably impact certain segments of the private non-residential sector.
In August, the Architectural Billings Index, a leading indicator for non-residential construction activity, moved above the 50 growth threshold for the first time in 5 months, improving to 50.2 from 48.7 in the prior month and has now improved sequentially for 3 consecutive months. Considering the high degree of variability in the index over the past year however, it is unclear whether this favorable trend will continue pending more positive signs in the economy and in the job market.
Despite the ongoing uncertainty in our markets as we move into fiscal 2013, we expect that our financial results will be favorably impacted by the anticipated benefits realized from the recently completed reconfiguration of our welded wire reinforcement operations and increasing contribution provided by the Ivy acquisition.
I’ll now turn the call back over to H.
H.O. Waltz
Thank you, Mike. Our Q4 results reflect the continuation of weak market conditions we’ve reported to you over the last several quarters.
Our expectation going into 2013 is for only a modest increase in shipments, pending a broader based economic recovery that would spur more robust job creation and construction activity. In view of these trends, we continue to focus on further cost reduction opportunities in our operations, and additional investments that broaden our product offering, reduce our operating costs, and enhance our ability to capitalize on an eventual recovery in demand.
H.O. Waltz
As Mike mentioned, our ESM expansion products remain on track, which entail the commissioning during our second fiscal quarter of new production lines at the North Carolina and Texas facilities, and the relocation of a third line to the Missouri facility. We previously indicated that these projects will enable us to reduce our operating costs, enhance our customer responsiveness and expand the scope of the rebar replacement options that we provide to the market.
Taken together, we expect that they will generate $15 million to $20 million of incremental revenues when fully operational and they should contribute to earnings during the current fiscal year.
Turning to our raw material markets, we continue to experience heightened levels of volatility since our last earnings call. After dropping precipitously in July, steel scrap prices rebounded in August only to fall off significantly again in September and in October.
While these fluctuations have generally translated into corresponding changes in the prices for our primary raw material, hot-rolled steel wire rod, our suppliers are motivated to use scrap market volatility as an opportunity to enhance their metal margins. Their ability to do so however is ultimately determined by the relative supply-demand balance in the marketplace.
The impact of declining wire rod pricing on the profitability of our industry ultimately depends on the competitive dynamics in our markets and ongoing uncertainty precludes us from forecasting margins over the next few months. As we’ve indicated previously we’re focused on providing quality products and exemplary service at competitive prices and maintaining our market leading position.
In summary, conditions in our markets for the first half of 2013 are likely to resemble those we’ve experienced for the last several quarters, characterized by the continuation of weak demand and highly competitive pricing environment. While we expect modest growth in shipments of engineered structural mesh over the next few quarters, the growth expectations for our other product lines are muted pending a broader based economic recovery or until we’re able to consummate an another acquisition.
This concludes our prepared remarks, and we will now take your questions. Sandy [ph], would you please explain the procedure for asking questions?
Operator
[Operator Instructions] Our first question comes from Tyson Bauer of KC Capital.
Tyson Bauer
Couple of quick items, you talked about the recent housing starts being better than what you’ve seen in years past, and that as kind of an early indicator for some of the non-res construction. Given your past cycles or your history here, what kind of time lag is typical and as a different -- disco around because we’re working off such small beginning numbers that even a small percentage increase although favorable, it may take a little longer to trigger some of these non-res construction numbers to improve quicker?
H.O. Waltz
Yes, I think -- I don’t know that -- know the historical relationships or their trends will necessarily repeat themselves this time, just given the magnitude of the downturn that -- that’s occurred. As you said, the housing start growth from a percentage standpoint has been pretty hefty, but that is often an extremely low base, relatively speaking when you go and look at the normal level over a longer period to be in the $1.5 million range or the peak level a few years ago, even with these high percentage increase is going to take an extended period to get back up to those levels.
And I’d say we probably expect the same that to be true for a non-res, that typically lags after housing. Housing is the first sector that turns up and then you gradually see improvement in non-res.
And I think at this point we expect the upturn to be gradual over an extended period.
Tyson Bauer
Is there a displacement that you’re viewing between public spending decline with the private sectors improving. Are we kind of in a rough path right now where those lines aren't matching up so we're ending up with a little bit of a void?
H.O. Waltz
Yes, earlier in the year we were seeing more of an upturn in private non-res and that’s consistent with the macro data. When you look at the spending data, there was a nice run up earlier in the year.
Then over the past few months -- the past 3 months in particular, there has been a drop-off. So at this point it’s difficult to say, I think some of that’s related to the increased uncertainty approaching the end of the year with all these political and economic issues.
So moving into next year we could see -- could be some improvement, but at this point it's unclear. And public -- the public sector spending has continued to decline and the recent extension of the federal highway funding bill should alleviate that and serve to mitigate that decrease.
But you still have budget pressures at the state and local level that are pushing it lower.
Michael Gazmarian
Tyson, one other point that I will make is, despite the fact that we saw some reasonably robust increases in private non-res spending earlier in the year, it really didn’t translate into a noticeable impact on our business which is I’m curious in some respect, but nonetheless a fact.
Tyson Bauer
I was going to -- that’s my last topic, when we did the Ivy transaction and combining 1 and 2 in several of your markets, one of the main tenants that we thought we were going to see is much better pricing power by your firm. We really have not seen that some transaction even now we have taken the cost out of the business.
Any thoughts there on why we haven’t had better pricing controls or ability with such a large market share?
H.O. Waltz
Well, I mean, I’m not so sure that we share that same feeling that we were going to have a whole lot of pricing power in this market. I think that with Insteel operating below 50% capacity is reasonable to expect that many of our competitors are doing the same and that conditions are very difficult.
It’s just a huge scramble in the industry for -- maybe not just market share, but for survival. So I think the difficult conditions have had bred desperate tactics on the part of lot of competitors and it's hard to say, when that changes.
