Alex Bauer
Executive Director of Investor Relations, TriNet

Thank you, operator. Good afternoon, everyone, and welcome to TriNet's 2021 first quarter conference call. Joining me today are Burton M. Goldfield, our President and CEO, and Kelly Tuminelli, our Chief Financial Officer. Our prepared remarks were pre-recorded. Burton will begin with an overview of our first quarter operating performance. Kelly will then review our financial results. We will then open up the call for the Q&A session. Before we begin, please note that today's discussion will include our 2021 second quarter and full year guidance and other statements that are not historical in nature, are predictive in nature, or depend upon or refer to future events or conditions, such as our expectations, estimates, predictions, strategies, beliefs, or other statements that might be considered forward-looking.

These forward-looking statements are based on management's current expectations and assumptions and are inherently subject to risks, uncertainties and changes in circumstances that are difficult to predict and that may cause actual results to differ materially from statements being made today or in the future. Except as may be required by law, we do not undertake to update any of these statements in light of new information, future events, or otherwise. We encourage you to review our most recent public filings with the SEC, including our 10-K and 10-Q filings, for a more detailed discussion of the risks, uncertainties, and changes in circumstances that may affect our future results or the market price for our stock. In addition, our discussion today will include non-GAAP financial measures, including our forward-looking guidance for net insurance margin, adjusted EBITDA margin, and adjusted net income per diluted share.

For reconciliations of our non-GAAP financial measures to our GAAP financial results, please see our earnings release, our 10-Q filing or our 10-K filing for our first quarter of 2021 and full year of 2020 reconciliations respectively, both of which are available on our website or through the SEC website. Reconciliation of our non-GAAP forward-looking guidance to the most directly comparable GAAP measures is also available on our website. With that, I will turn the call over to Burton for his opening remarks. Burton?

Burton M. Goldfield
President and CEO, TriNet

Thank you, Alex. The first quarter of 2021 saw a continuation of many of the positive trends that TriNet experienced throughout 2020. Our strong customer base showed resilience as well as significant growth in the first quarter of 2021. I am proud of the TriNet team and their ability to help our customers navigate the current economic climate. We continued to put our customers at the center of everything we do, and in the first quarter, we were again rewarded with strong operating and financial performance. During the first quarter, we grew GAAP total revenues 1% year-over-year to approximately $1.1 billion. I am especially pleased with this revenue growth as the year-over-year comparison was positive against a pre-pandemic quarter in 2020.

Furthermore, this revenue growth was supported by our installed base of customers who have committed to TriNet at high retention rates and grew with us during the first quarter. Extrapolating off our Q1 trend and the continued reopening of the U.S. economy, I would expect continued outsized hiring in our install base throughout 2021. GAAP earnings per share grew 15% year-over-year to $1.51 per share. Our revenue growth, coupled with the reduced healthcare cost and expense management, drove our first quarter GAAP EPS growth. Finally, we finished the first quarter with approximately 326,000 WSEs, down 3% year-over-year and down 2% sequentially versus the fourth quarter of 2020. These year-over-year and sequential metrics reflect lower churn than what we've seen in a typical January, but also lower contribution from new sales when compared to our pre-pandemic experience.

We are increasingly optimistic as we look out on the balance of 2021. The lower churn or higher retention rate we saw in January was in part driven by our 2020 Recovery Credit program. In fact, we lost less than 1% of the customers who participated in the 2020 Recovery Credit program. Furthermore, the strength and resilience of our customer base was key to our first quarter volume and business performance. Our customer base hired the most new employees during a first quarter in our 30+ year company history. Putting together the higher retention with the strong customer hiring, three of our core verticals, technology, financial services, and life sciences, significantly outperformed our other verticals. This outperformance even includes absorbing an incremental percentage point of uncontrollable attrition from mergers and acquisitions in our technology vertical. This increased M&A activity in technology reflects a vibrant industry already on the rebound.

Turning to new sales during the quarter, we closed some of the sales gap from our pre-pandemic sales performance, but still have an opportunity for improvement. As inferred from our forward-looking guidance found in our earnings release, we expect new sales momentum to build during the year. As we look forward to the second quarter and the balance of 2021, we are encouraged by how the economic reopening and recovery has positively impacted TriNet. Although we do not guide to WSE count, I am confident in the growth of WSEs during the second quarter. We look forward to updating you as the year progresses. For nearly a decade, we targeted our sales and service efforts on our core verticals, including technology, financial services, professional services, life sciences, non-profit, and Main Street.

In doing so, we have built a group of dynamic customers who represent the innovative spirit of America's small and medium-sized businesses. We remain confident in the effectiveness of our vertical strategy. The true value of this customer base revealed itself during the pandemic. While we worked tirelessly in service of our customers, our customers responded by continuing their relationship with TriNet while managing through the economic shock. Beginning in June of 2020, as the pandemic-related lockdowns started to ease, our installed base began to hire workers, a trend that has continued unabated since that date. As noted, the first quarter of 2021 saw TriNet's customers hire the most new employees in any first quarter in TriNet's history. The value proposition remains particularly strong. Prior to the pandemic, our customers experienced fierce competition for talent. TriNet provides them with an advantage through our differentiated service and benefits offering.

As the economy improves throughout 2021 and business reopenings accelerate across America, we expect our installed base to leverage our solution while continuing to hire and compete for scarce talent. In the first quarter, the technology vertical was the hiring growth leader. We also experienced strong hiring from the financial services and life sciences verticals. The economic reopening and recovery has highlighted that TriNet is much more than a vendor to our customers. An example of this relationship is the creation of our 2020 Recovery Credit program. This Recovery Credit program is our effort to share with our customers the excess cost savings we generated from underutilized health services, primarily in April of 2020. Through the first quarter of 2021, we have accrued a total of $140 million for the 2020 Recovery Credit program.

Beginning in the fourth quarter of 2020, we have been busy returning these funds to our customers. In fact, in the first quarter, we returned $27 million to our customer base. As a result of the 2020 Recovery Credit program, well over 50% of our installed base who have renewed with TriNet are now signed to annual contracts. This has the impact of stabilizing our installed base, increasing our predictability, and improving the renewal dialogue with our customers. During the first quarter, we again saw significantly lower health costs. As a result of this performance, we once again put all of our stakeholders first and established a new 2021 credit program. For this program, we accrued an incremental $25 million. The 2021 credit program is structured differently from our Recovery Credit program.

It is our expectation that health costs will rebound over the course of 2021, which has already been captured in our forecast. As such, the amount of the 2021 credit program available to our customers will be contingent upon the full year performance of our health costs. Kelly will provide more details later. Ultimately, we believe the primary long-term outcome for 2021 credit program and the 2020 Recovery Credit program will be measured by greater customer satisfaction and retention. Finally, as the economic reopening and recovery take hold, we expect new sales to continue to improve throughout 2021. As we previously noted, when the pandemic began and the lockdowns proliferated beginning in March of 2020, our new business growth dropped significantly from our pre-pandemic levels.

Our prospects became far more concerned with the front of their business versus the back office of their business, or the survivability of their business rather than their HR services. In response, we had to change our approach to new sales as well as account for social distancing, which became the norm. As we reflect on our first quarter 2021 new sales performance, we finally saw the gap with our pre-pandemic performance begin to shrink. We continue to add customers in our core verticals as we highlighted how being with TriNet is so much more than a vendor relationship. As we look forward to the rest of 2021, we expect to build new sales growth through the balance of the year as business activity re-accelerates. In summary, I am pleased with our financial performance.

Our vertical strategy has once again become validated through the durability of the customer base and our customers' continued record hiring and growth in the first quarter. Our 2020 Recovery Credit program achieved an acceptance rate of well over 50% across the fourth quarter of 2020 and first quarter of 2021, contributing to retention and resulting in a more predictable customer base. New sales are recovering, but we still have opportunities for improvement. Consistent with the guidance outlined in our earnings release, we expect sales to improve throughout the year. Ultimately, TriNet has demonstrated its commitment to our customers throughout the pandemic and beyond, and we believe we can leverage that commitment to drive growth in the future. I will now turn the call over to Kelly for a review of our financial performance. Kelly?

Kelly Tuminelli
CFO, TriNet

Thank you, Burton. I'll review our first quarter financial results before discussing second quarter and full year 2021 guidance. With respect to our first quarter financial performance, I'm very pleased with our results. We again benefited from our recent trends, strong performance from our installed base, coupled with reduced health costs. During the first quarter, GAAP total revenues increased 1% year-over-year, and professional service revenues were down 2% year-over-year, reflecting the 3% lower ending WSEs. GAAP total revenues came in slightly below our guidance as we accrued $37 million in the first quarter, $12 million for the existing Recovery Credit program started in 2020, and an additional $25 million for our new 2021 credit program. Combined, these items reduced GAAP revenue by 3%. The 2021 credit accrual differs from our 2020 Recovery Credit program. First, this contra revenue accrual is allocated against insurance revenue only.

Second, dispersion of this accrual is contingent upon the full year performance of our health costs. It is our expectation that health costs will rebound in the second half. If costs do rebound greater than what we're currently anticipating, the accrual will be reduced proportionally in line with the excess costs up to $25 million. If costs do not increase greater than what we're forecasting, these funds will be made available to a portion of our customers. In the quarter, average WSEs declined 4% to 321,000 compared to a pre-pandemic first quarter 2020. As Burton discussed, we once again benefited from our customer selection as our installed base continued to hire. We did see some volume headwind of nearly 1% as our technology vertical experienced higher than normal M&A activity. Finally, we believe we have fortified our installed base for 2021 through our 2020 Recovery Credit program.

Net service revenue in the quarter increased 9% year-over-year, largely driven by the outperformance of our net insurance margin. For the first quarter, we delivered a net insurance margin of just over 17% versus our first quarter guided range of 12.5%-14.5%. Net insurance margin outperformed in the quarter as we benefited from larger positive claims development as our fourth quarter reserves were paid during the first quarter. Given the higher paid claims activity in December, we had assumed higher levels of incurred but unpaid health costs. In fact, COVID-19 testing and vaccination costs were slightly higher than our forecast. However, once again, these higher than forecasted COVID-19 related costs were more than offset by reduced overall health services utilization, as we saw the paid claims activity in January and February play out. This underutilization enabled us to set aside $25 million for our 2021 credit program.

In the first quarter, we delivered an adjusted EBITDA margin of 53%, five points above the top end of our guidance. We spent approximately $60 million to repurchase approximately 744,000 shares of stock in the first quarter. In addition, we reshaped our debt structure during the quarter, issuing longer-dated debt at a favorable 3.5% interest rate. Our first quarter effective tax rate was 25%. In the quarter, the rate was lower due to the timing differences from the tax treatment of employee equity compensation. GAAP net income per share increased 15% to $1.51 compared to $1.31 per share in the same quarter last year, exceeding the top end of our guidance range by $0.17. Adjusted net income per share increased 18% to $1.66 compared to $1.41 per share in the same quarter last year, which exceeded the top end of guidance by $0.27.

Overall, we view the first quarter as a really good start to 2021 as our core performance funded both a customer credit and allowed us the ability to lock in longer duration debt. Turning to our 2021 second quarter and full year outlook, I will provide both GAAP and non-GAAP guidance. Please recall that the initial accrual in second quarter of last year for our 2020 Recovery Credit program represented approximately 6% of GAAP total revenues and professional service revenues for the period. For the second quarter of 2021, we expect GAAP revenue growth of 12%-14% year-over-year, and professional service revenue growth to be in the range of 10%-14% year-over-year. Please note that in the second quarter, we expect to accrue just $5 million for our 2020 Recovery Credit program.

The second quarter will be the final quarter where we accrue any meaningful amount for the 2020 Recovery Credit program. As such, the total amount accrued for this program and made available to customers will be $145 million. Regarding net insurance margin, we are forecasting a second quarter margin of between approximately 10% and 11%. In the quarter, we expect COVID-19 related costs to continue, primarily comprised of testing and vaccine administration, as well as the normalization of healthcare utilization. Additionally, please recall that our adjusted EBITDA margin and earnings per share in the second quarter of 2020 benefited significantly from the reduced health costs as health behaviors changed in response to COVID-19 protocols last year. We do not anticipate that recurring. We are forecasting our second quarter 2021 adjusted EBITDA margin to be in the range of 35%- 39%.

We expect second quarter GAAP earnings per share to be in the range of $0.59-$0.74 per share, or down versus last year due to last year's significant underutilization of health costs. Finally, we expect second quarter adjusted earnings per share to be in the range of $0.70-$0.86 per share. Turning to our full year guidance, given our very strong first quarter performance, we are making a few changes. As I discussed earlier, we do expect health costs to rebound in the second half of 2021. In light of that, we believe our full year guidance is partly de-risked by the fact that our 2021 credit program will be adjusted downwards by up to $25 million should we experience additional health costs above our current expectations.

Furthermore, the strong hiring and retention of our core verticals has improved our outlook, and we've pulled up the bottom end of our guidance range. We are now forecasting our year-over-year GAAP revenue growth to be 9%-11%, lifting the bottom end of our range by 1 point. Our professional service revenue forecast is now 8%-10% year-over-year growth, an increase of 2 percentage points. The increase in our professional service revenue growth forecast is a result of strong hiring growth, retention in our core verticals, and resilient pricing. We expect our 2021 net insurance margin to remain in the range of 10%-11%, and we will closely be watching the developments and trends given our expected increase in utilization of health services in the second half of the year.

Our full year 2020 adjusted EBITDA margin is now expected to be in the range of 38%-40%, up one point on the bottom end of the range. We now expect GAAP EPS to be in the range of $2.86-$3.31, an increase of $0.07 on the low end of the range, while the high end of the range remains unchanged. This reflects our strong core performance, which is funding the 2021 credit program, as well as covering the increased cost associated with our recently completed debt offering. Adjusted net income per share is now expected to be in the range of $3.42-$3.90, or down 23% to down 12% year-over-year. The new adjusted net income per share guidance reflects a $0.07 increase to the bottom end of the guidance range. With that, I will return the call to Burton for his closing remarks. Burton?

Burton M. Goldfield
President and CEO, TriNet

Thank you, Kelly. In summary, our long-term commitment to our vertical strategy resulted in a vibrant and resilient installed base of customers. Our customers hired new employees at record rates, and we continued our strong financial performance. We once again leveraged our unique business model and financial performance to offer another credit program for the benefit of all our stakeholders. As the vaccination process takes hold and the economy continues to reopen, we will continue executing our vertical strategy and build momentum in our business. We are well-positioned to return to volume growth in 2021. Operator?

We will now begin the question-and-answer session. To ask a question, you may press star then one on your touch-tone phone. If you are using a speakerphone, please pick up your handset before pressing the keys. To withdraw your question, please press star then two. Our first question today comes from Tien-Tsin Huang with JPMorgan.

Tien-Tsin Huang
Analyst, JPMorgan

Thank you. Thanks so much for your remarks. Maybe I'll start, Burton. Hey, good afternoon to you guys. Just, Burton, I want to ask you about new sales. I'm curious if your thinking or your targets for new sales for the calendar year has changed versus 90 days ago. I know the prior outlook assumes some different ranges or outcomes around new sales. Has the rhythm of sales, are you thinking around that changed at all?

Burton M. Goldfield
President and CEO, TriNet

Yeah.

Tien-Tsin Huang
Analyst, JPMorgan

Is insurance still sort of the holdup for the SMBs to make a change here?

Burton M. Goldfield
President and CEO, TriNet

I think about it every day, Tien-Tsin Huang. We started to close that gap from the pre-pandemic quarter, which was very encouraging as far as I can tell. I can't tell you when we return to normal, which includes selling in front of our prospects. I'm very happy with the rollout of the vaccines, and I love the way the model is showing during the pandemic, as reflected by not only closing the gap but retention rates, et cetera. You know me well enough to know I'm pretty impatient, and I'm glad that the gap is shrinking, but I want to be selling more to those right customers in the right verticals at the right price. I'm cautiously optimistic, and I'm highly focused in this area.

Tien-Tsin Huang
Analyst, JPMorgan

Got you. Yeah, we'll keep tracking it.

Burton M. Goldfield
President and CEO, TriNet

Yeah.

Tien-Tsin Huang
Analyst, JPMorgan

Maybe I'll ask my quick follow-up on the net insurance margin outlook here. Q1, like you said, was way better than expected. Full year is unchanged. The recovery, this new credit makes a lot of sense. I'm curious, just the line of sight on healthcare utilization for the rest of the year. Has that thinking changed at all? I know you have some cushion with the credit, but it's another question around visibility on the utilization side. Thank you.

Kelly Tuminelli
CFO, TriNet

Well, good to hear from you, Tien-Tsin. As I'm thinking about utilization and kind of what we saw in the month of March, we did see things like normal doctor visits come back. We did see lower utilization in terms of the flu and respiratory things, probably due to social distancing. We also saw higher utilization, as I mentioned in my prepared remarks, of both testing and vaccines. We're cautious as we're looking forward because we're not sure how big that bounce back will be, and we think our guidance really reflects that level of caution, and it's just prudent this early in the year.

Tien-Tsin Huang
Analyst, JPMorgan

Yeah. Okay. Thank you, Kelly. Thank you, Burton.

Burton M. Goldfield
President and CEO, TriNet

Thank you.

Our next question comes from Kevin McVeigh with Credit Suisse.

Kevin McVeigh
Analyst, Credit Suisse

Great. Thank you so much, and congratulations on the results.

Burton M. Goldfield
President and CEO, TriNet

Thank you, Kevin.

Kevin McVeigh
Analyst, Credit Suisse

You're very welcome, Burton. It's well done for sure. Hey, as you're thinking about the retention of folks that are leveraging the credits versus non, is there any way to maybe think about the brackets of overall retention and then what the experience is for folks that are taking the credit versus not?

Kelly Tuminelli
CFO, TriNet

Kevin, I'll take that.

Kevin McVeigh
Analyst, Credit Suisse

Okay.

Kelly Tuminelli
CFO, TriNet

When I'm looking at people that have participated, for the customers that participated, I think Burton mentioned it in his prepared remarks that over 50% of our renewal base has participated fully in our Recovery Credit program, and less than 1% of those have attrited. We have had a noticeable difference in terms of attrition between those that fully participated in the Recovery Credit and those that didn't. Did that answer your question?

Kevin McVeigh
Analyst, Credit Suisse

It did. I apologize, I missed that. Kelly, as you think about the margins at the lower end, is 10% the floor in terms of as you would think about the progression of the quarters where would it have to be the full year before you reverse any of that? In terms of from a downside perspective, can we think it as 10% for a floor, or would have to see how the full year played out before you'd revisit those accruals?

Kelly Tuminelli
CFO, TriNet

I think we're going to be prudent, and we're going to watch the year as it develops. I appreciate the question, but we did set 10% as the low end of our guidance for sure.

Kevin McVeigh
Analyst, Credit Suisse

Super. Thank you so much.

Burton M. Goldfield
President and CEO, TriNet

Thank you, Kevin.

Our next question comes from Andrew Nicholas with William Blair.

Andrew Nicholas
Analyst, William Blair

Hi, good afternoon.

Burton M. Goldfield
President and CEO, TriNet

Good afternoon.

Andrew Nicholas
Analyst, William Blair

I understand the current environment is a bit unprecedented from a healthcare utilization perspective, but I'm wondering, given you've now instituted a second credit program, do you expect this to become a more permanent aspect of your pricing strategy going forward? If you could kind of walk us through the thought process for why that would or would not make sense, in 2022 and beyond, that'd be really helpful. Certainly seems like the program in its 2021 form will help limit some of the variability you experience on the insurance margin side, which I would imagine would be a positive development for the company going forward. Just your thoughts there would be great.

Burton M. Goldfield
President and CEO, TriNet

Yeah, great question. The transparency and value creation for our customers is a real critical aspect of our model, which as you know, is pretty unique in our industry. You mentioned a couple of the key points, is lack of volatility, et cetera. The bottom line is, our first program, the Recovery Credit program, demonstrated to our customers the depth of our partnership and the foundation for the long-term relationship, and it was expressed in a clear benefit. As Kelly told you, over 50% of our WSEs are employed by customers who have committed to the annual contracts through the program, and of those customers, less than 1% have attrited. It worked out and exceeded my expectations.

As you look at it going forward, this was a way for TriNet stakeholders to benefit from the Recovery Credit program, I am going to continue to look for innovative ways that we can differentiate ourselves by partnering with the customers.

Andrew Nicholas
Analyst, William Blair

Makes sense. Thank you. For my follow-up, changing gears a little bit.

Burton M. Goldfield
President and CEO, TriNet

Sure.

Andrew Nicholas
Analyst, William Blair

I was hoping you could help us get a better sense for how you're thinking about the impact of the past year on the workers' comp book. How much of what I would assume was much lighter claims activity in 2020, how much of that has already been accrued for? If not, when would you expect that to flow through, in the form of prior period adjustments? Thank you.

Kelly Tuminelli
CFO, TriNet

I appreciate the question. We did see favorable performance in workers' comp in 2020. Most certainly, as we're looking forward, I think we priced our workers' comp appropriately given the environment and given our expectation for loss. We will continue to watch the trends and see how it comes out. I think you've noticed, though, a portion of prior period development coming through, maybe a little bit smaller this quarter than we've seen in past years.

Andrew Nicholas
Analyst, William Blair

Great. Thanks again.

Burton M. Goldfield
President and CEO, TriNet

Thank you.

Operator

Again, if you have a question, please press star then one. Our next question will come from Sam England with Berenberg.

Sam England
Analyst, Berenberg

Hi, guys. Thanks for taking the questions. The first one, I was just wondering, as we come out of the pandemic, how you think remote working trends might impact both TriNet and the PEO industry in general. Has it been something that's driven some of the new inquiries that you're seeing?

Burton M. Goldfield
President and CEO, TriNet

A great question. I believe we're emerging from the COVID-19 pandemic in a solid position, and that our customers will continue to hire additional employees to support their business and growth plans. Many of those employees will be remote, and there's tremendous complexity, particularly if you cross state lines as it relates to hiring and retaining those employees. That complexity is suited particularly well for our business model because we can make sure that they're paid right, the taxes are paid right, and they have great benefits in all 50 states. I believe that the combination of the model itself, as well as our long-term commitment to this vertical strategy and the hiring that's occurring, bodes well for the future.

Sam England
Analyst, Berenberg

Great. Thanks. The follow-up, I was just wondering how you're thinking about the M&A environment in 2021 and also longer term. Has the pandemic, do you think, impacted people's willingness to sell businesses? Yeah, some thoughts around that would be great.

Kelly Tuminelli
CFO, TriNet

Yeah. Sam, this is Kelly. I'll take that one. One thing I noted on the M&A front, I think it is still a robust M&A environment. I think Burton in his prepared remarks talked about the M&A for the tech sector and that it had about a 1% impact on our WSE count. Due to a robust M&A market. How we're thinking about M&A specifically, it really hasn't changed. In terms of capital prioritization, first, we're going to look at organic growth. Second, we will look at M&A, but it's got to fit our strategy and the type of business or geography where we want to be. Lastly, we will participate in share repurchase opportunistically and at least to cover our dilution.

Sam England
Analyst, Berenberg

Great. Thanks very much.

Burton M. Goldfield
President and CEO, TriNet

Our next question comes from David Grossman with Stifel.

David Grossman
Analyst, Stifel

Thank you. Good afternoon.

Burton M. Goldfield
President and CEO, TriNet

Hi, Dave.

David Grossman
Analyst, Stifel

Hey, Burton. I was hoping maybe you could shed a little more light on the WSE dynamic. I think Kelly just reiterated what you had said in your prepared remark about a point impact from M&A. If I look at that sequentially, it looks like WSEs were still down sequentially, even after normalizing for that. Maybe you could help us understand just kind of where we are in this dynamic of kind of puts and takes in that WSE base and, with the recovering economic situation, is there some dynamic, and you had really high retention, just wondering why we were still down sequentially. What other factors are at play here?

Kelly Tuminelli
CFO, TriNet

Yeah. Let me take that, then I'll pass it on to Burton to add anything he wants to related to that. As we look at it sequentially, usually first quarter or January rather, is when a lot of people change PEOs. They change it because they want to keep their WSEs with one W2 for the year, possibly. We do see probably the most churn in the month of January. After that, we have seen growth. As I'm thinking about our sectors, we saw hiring in tech, financial services, and life sciences very strong. Even though there was a lot of M&A activity, we still saw very strong net hiring. Hopefully as the vaccine comes out or as more people get fully vaccinated and things open up even more, we'll see other sectors follow on.

Actually, in the first quarter, and then I'll pass it to Burton, for every single vertical except nonprofit, we saw positive hiring, if that helps. Yeah. Burton, you want to add anything?

Burton M. Goldfield
President and CEO, TriNet

Yeah. David, I would point you to Main Street, which has not recovered yet. What I'd point you to is professional services fees were up, and I was pleased with the revenue generated from our PSF, taking out the net insurance margin. For me, it was a strong quarter, and I believe that frankly, Main Street will recovery over time as well. The hiring in the other verticals was great. Main Street has not recovered for us yet, but ultimately, I am very comfortable with where we ended Q1 as a great quarter to start from for the rest of the year.

Kelly Tuminelli
CFO, TriNet

Yeah. One other thing to add to that is, you may not have seen it yet, but if you look at our guidance specifically, we did raise our PSF guidance by about two points. Our guidance really includes our view of WSEs into the future and our perspectives on hiring, sales, attrition. I think it bodes well by being able to raise our PSR guidance by 2%.

David Grossman
Analyst, Stifel

Right. Just kind of rolling all that together, though, is it really the sales dynamic in calendar 2020 that gated the WSE growth in the March quarter, just given, again, retention it sounds like was really good and hiring was pretty good except for maybe Main Street. Is it that dynamic that we're seeing in the first quarter? I mean, of course, you're mathematically into the quarter, you're going to have growth if you hold that for the balance of the year. Just really trying to understand, is it really just the new sales dynamic last year that gated the WSE count in the beginning of the year or at the end of the first quarter here?

Kelly Tuminelli
CFO, TriNet

Yeah. Well, typically we have seen Q1 be down lower sequentially in January. New sales did close some of the gap. It is still lagging pre-pandemic. We were actually a little bit better from an ending WSE perspective than was in our initial guidance.

Got it. Just going to the recovery credit, I just want to make sure I understand the various dynamics there. It sounds like we're setting up a buffer for some of the volatility that we typically would see while continuing to give back and enhance retention. I don't know if there's going to be a new normal, but I think historically we were thinking of what, like 11%-13% net insurance margins in a normalized environment. Is that how you want us to think about the business with the credit coming and going year in and year out? Or do you have a thought on what the more normalized level should be, including kind of the accrual of the recovery credit or a release when appropriate?

Kelly Tuminelli
CFO, TriNet

Yeah. Our guidance for 2021 really is a 10%-11% combined net insurance margin. We don't attempt to make money on health insurance overall, but we do price it to be able to cover our costs and our balance sheet risks. 10%-11% is appropriate for 2021, and we're going to continue to watch trends as we move forward. I'm not going to give a further outlook than that at this point, David.

David Grossman

Got it. Just one last question. Sorry for the third question here.

Burton M. Goldfield
President and CEO, TriNet

No, that's okay.

David Grossman

This is just a cleanup modeling question. Did you say 3.5% interest on the new debt or do you want to just maybe you just can let us know what you think your interest expense will be for the year?

Kelly Tuminelli
CFO, TriNet

Yeah, sure. It was a 3.5% coupon on $500 million of debt that was refinanced. In terms of the guidance that we gave on a year-on-year basis or quarter-on-quarter, I should say, we built in roughly $0.11 incremental associated with interest expense by being able to lengthen out that debt.

David Grossman
Analyst, Stifel

Okay. That's $0.11 year-over-year?

Kelly Tuminelli
CFO, TriNet

Yeah. $0.11 really versus our guidance we gave last quarter. We anticipate it'll hit us by about $0.11. By not raising the top end in effect was raising guidance by $0.11 because we covered off the debt financing cost.

David Grossman
Analyst, Stifel

Got it. Okay, great. Thanks very much.

Burton M. Goldfield
President and CEO, TriNet

Thanks, David.
