Earnings Call Transcript 2018-Q3

[Operator]

Good day, ladies and gentlemen, and welcome to the Interactive Brokers Group Third Quarter Financial Results Conference Call.

At this time, all participants are in a listen-only mode. Later, we will conduct a question-and-answer session and instructions will be given at that time. [Operator Instructions] As a reminder today's program maybe recorded.

And now I'd like to introduce your host for today's program, Nancy Stuebe, Director of Investor Relations for Interactive Brokers. Please go ahead.

[Nancy Stuebe, Director of IR]

Good afternoon, everyone. Thank you for joining us to review our 2018 third quarter performance. Once again, Thomas is on the call, but asked me to present his comments on the business. He will handle the Q&A.

As a reminder, today's call may include forward-looking statements, which represent the company's belief regarding future events, which by their nature are not certain and outside of the company's control. Our actual results may -- and financial condition may differ possibly materially from what is indicated in these forward-looking statements. We ask that you refer to the disclaimers in our press release. You should also review a description of risk factors contained in our financial reports filed with the SEC.

This quarter saw several new developments in Interactive Brokers. I will start with our decision to move our primary listing to the IEX exchange. I want to emphasize that our stock continues to trade at all the exchanges it did before, but by moving our primary listing to IEX, we believe investors buying or selling our shares will get better prices.

Typically executions on the IEX are down at the midpoint of the bid ask spread, which is better than where they are done on another exchanges. This is because IEX has a discretionary midpoint peg order that allows traders to post limit orders at the midpoint and give the exchange the discretion to cancel the order for three milliseconds at the time when limit orders at other exchanges are crumbling and then reinstate the order at the new midpoint.

So it is the combination of the exchange at speed bump with their crumbling order software routine that makes us an effective order type with a limit order that gets picked off much less often. Anyone interested, should go to the IEX website and read up on the facility.

IEX's signature feature speed bump of a few milliseconds is better for investors because high frequency traders, the traders who buy retail order flow from other brokers, cannot take advantage of the order.

When there are middlemen involved, as they are another mouth to feed, costs are raised, not reduced. It is our goal to make sure the cost to invest is as low as possible and then to give that benefit to the investor, we do not want that benefit to go to the middlemen who buy order flow and then trade against us. We are pleased to be the first company to list on IEX and we expect many more companies to follow us.

Once again, in this quarter, we set new records in our brokerage business. Our customer equity reached $142.5 billion, up 23%, but we also hit an all-time high in customer accounts up 26% to 576,000.

Margin lending at $30.7 billion outstanding was up 22% from the year ago quarter and was also up sequentially. This growth led to a net revenue increase of 21% in our brokerage business, with its pretax margin reaching 66% for the quarter.

DARTs this quarter was 763,000, up 10% over last year, but they were down from the more active first and second quarters. Market volatility as measured by the VIX slowed to an average of 13 in September and was coming down steadily from its 2018 monthly average high of 22 in February.

Since quarter end, the VIX has risen again. Our DARTs increase comes more consistent account growth and not from the [indiscernible] acquisitions.

We expanded the range of financial services we offer to our customers this quarter. Through our integrated investment management program, we support many different types of transactions from one account. First, our clients are in the best interest rates and their available cash, currently 1.68% on U.S. dollars in qualified account, without having a transfer from one account to another.

Given that many banks and brokers pay only a small fraction of 1%, we see this as a huge opportunity to bring in new customers and new deposits and we keep pushing this message in our advertising.

Customers can now also deposit their paycheck directly into their IBKR account and immediately start to earn those high rates and use our newly introduced Bill Pay function to pay bill. Our debt MasterCard allows our customers to pay expenses or make purchases where they can borrow against their account at our industry-low interest rates and they can do all this as well as investments securities in over 120 market centers worldwide at low cost seamlessly from one account.

The greener grass syndrome is spreading through the industry. JPMorgan is offering free trades by selling their customer's orders to high frequency traders, while we are offering high rates on deposit. We've got more to gain or lose. I like our position. We'll have more to say about zero commissions in our coming advertisements.

I am asked many times how it is that we continue to grow at such high rates and when will it stop? The answer is, it will continue as long as we adhere to our commitment to focus on building automation.

This enables us to continue to compete on price, to offer ever broader account capabilities and geographies, low commissions and low interest rates and margin borrowing, high interest rates on cash and best price execution on trades. Individually and collectively, these capabilities attract perspective clients and contribute to the growth of our business.

Further, many of the market segments we operate in our large, global and growing, potential customers are well aware of the importance of keeping costs down and revenues up especially in an environment where there is downward pressure on the fees.

So the prices we charge versus our competitors and the interest we pay on cash balances along with the international access on technology we offer are important points of differentiation that we talk to many potential customers about worldwide.

To reach them, we advertise on business media and in locations that reach the select customers we target as well as on social media. We also have 40 experienced sales people who are well-versed in our products, a team that we grew over decades.

It takes more than a year to train someone who is experienced in the field and all that our platform can do across multiple customer types in multiple countries, which have different demands and requirements. Our salespeople are located around the world and they do everything from attending conferences and industry events to keeping track of new asset managers launching to maintaining contact with both existing firms who may be looking to make a change and with existing clients who recommend us to friends and colleagues.

About half of our business comes from word-of-mouth. So the bigger we grow and the more people that are on our platform, the more people there are who talk about us and what we can do for a trader or investor.

Pretext profit for the quarter was $276 million, adding back the $23 million for this quarter's unfavorable currency impact net of treasury marked gains gives us $299 million or 65% pretax margin. Brokerage was $291 million of this and achieved a 66% pretax margin.

Now for the breakdown by customer of how our brokerage business is evolving. Once again, in all our customer segments, we saw strong growth in accounts, client equity and commissions. For the third quarter, hedge funds and proprietary trading firms were 4% of our accounts of 11%, 19% of our client equity up 12% and 25% of our commissions up 16%. Our low margin rates and high cash interest continue to attract institutions in the competitive space, which is highly focused and execution price and overall cost. Growth in this area was strong and both developed and developing geographic markets.

Individual customers made up 49% of accounts up 19%, 35% of customer equity up 22% and 50% of commissions up 18%. Customer equity was driven by double-digit strength in all geographic regions, particularly in developed markets internationally as word-of-mouth about our platform has spread.

While market volatility is down sequentially, commissions benefited from higher volatility and account growth versus last year's third quarter. Investors continue to become more aware of the practice of brokers selling their customers orders to high frequency traders, which is now part of the class-action suit. This is a practice that gives investors lower prices on their sell orders and forces them to pay higher prices on their buy and is something we at Interactive Brokers do not do with our customer's orders.

We also see individuals who on global access among cost, not only on commissions and margin financing, but also on FX as a trade internationally, which all plays to our strength.

Registered Investment Advisors represent 17% of our accounts, which is up 16%, 24% of our customer equity up 24% and 17% of our commissions up 16%. The RIA segment is benefiting from our new products, our EDPs account mass upload capability, low commission rates and high interest on cash balances, as well as the important facts that we do not charge an RIA multiple fees to allocated trade among multiple customer account.

We also offer free Customer Relationship Management or CRM software as well as reporting tools that mean an RIA does not have to pay for third-party services. In an environment with downward pressure on fees, our ability to save an advisor money while providing excellent performance reporting and functionality has grown increasingly important.

Finally, Introducing Brokers represent 31% of our customer accounts, up 48%, 21% of our customer equity, up 36% and 9% of our commission income, up 37%. As we discussed last quarter, our Introducing Broker segment continues to benefit from the tailwind of two major trends, the increasing regulatory burden worldwide, which makes outsourcing your back office the best solution and the growth of the new investor class in developing countries many of whom want to trade internationally.

This quarter, we introduced our integrated investment management program, which consolidates the variety of financial transactions you can do from a single interactive brokers account. Without having to transfer funds between account, customers automatically get the best interest rate on both their cash, earning market rate interest on idle balances and on their securities, earning extra income by lending out their fully paid shares.

Integrated Investment Management also includes our debit MasterCard, our new Bill Pay function and payroll direct deposit, giving our customers more reasons to stay on our platforms to transact their financial business.

Our Insured Bank Deposit Suite program, which offers customers up to $2.75 million in SIPC and FDIC insured deposits, continues to grow and reach $1.6 billion this quarter.

Finally, we are looking forward to announcing access to Israel on our platform in the fourth quarter and now Paul Brody will take you through the numbers, Paul?

[Paul Brody, CFO]

Thank you, Nancy. Welcome everyone on the call. Thank you for dialing in. I am going to review our results as usual and then we'll go on to some detail on the drivers behind the numbers and then we'll take questions.

Let me begin by highlighting that our headline numbers for net revenues and pretax income imply a 3% year-over-year increase for both of those measures, but when we remove the effects of non-core operating items, primarily from our currency diversification strategy and the sale of our U.S. marketing business in 2017, those numbers rise to 19% and 29% respectively and I'll get more detail on this in my review of the financials.

So let's turn first to the operating metrics, which reflected strong growth in customer accounts, equity and cash balances, while trading volume was generally in line with market volatility. The volatility is measured by the average of VIX rose to 12.9 this quarter up 18% from 11% in last year's third quarter.

Sequentially however, this quarter's average of VIX declined from 15.4% in the second quarter and from 17.2% in the first quarter after a particularly volatile February and March. The increased volatility over a year ago quarter let to an 8% rise in options trading volume, futures and stock of volume and volumes were off 4% and 20% respectively.

The decline in stock trade volumes was laid -- was due to lighter trading in low priced stocks and an increase in the proportion of trading in higher priced stocks. As a result of this shift of a number of shares traded declined and the dark [ph] and commissions on stocks both rose. Finally, foreign exchange volume was down as well.

Total accounts grew to 576,000 and up 26%, which contributed to customer equity growth of 23% to $142.5 billion. We saw growth in all customer segments, particularly in Introducing Brokers and in Financial Advisors.

With the continued tailwind from new account growth, our quarterly total DARTs were up 10% versus last year. Our overall average cleared commission per DART fell 5% year-on-year to $3.78 on a product mix that featured smaller average trade sizes in stocks options and Forex and slightly higher in futures.

Moving on to net interest margin table, our net interest margin widened to 1.68% from 1.31% in the third quarter last year. The federal reserve rates raised rates again this quarter in late September, making a total of four increases in the fed funds target rate since December 2017.

Due to careful management of our short duration portfolio, we recorded a modest mark-to-market gain of about $1 million on our holdings of U.S. treasuries. As always, we plan to hold these securities to maturity, but as brokers unlike banks GAAP rules require us to mark them to market in our financial reporting.

U.S. rate increases together with increased customer balances generated more net interest income on cash balances. We believe our continued success in asset gathering should lead to larger contributions from interest sensitive assets going forward.

Our FDIC insured bank deposit sweep program introduced late last year, continues to grow and reached $1.6 billion. Margin lending and segregated cash management were the most significant contributors to our net interest margin.

Average margin loan balances grew 22% versus last year, which combined with higher interest rates led to margin interest growth of 72%. Our segregated cash interest income rose 52%, primarily on fed hikes to US interest rates. Two factors caused the yields on our segregated cash to not precisely match the increases in fed funds rate.

First, currently about 15% is held in other currencies, although recently 11% of that is held in currencies that also showed various elevated interest rates during the quarter. And second, given the current average duration of investment in treasuries of slightly under 90 days and given that about 18% of the portfolio is not pick up in new yield until a subsequent quarter, these amounts would not be expected to follow a fed hike immediately.

Year-over-year decline in segregated cash balances is a function of increase in margin loans of cash swept to our FDIC sweep program and of more customer cash being put to work in the securities markets. Starting with the month of September, we began to break out in our metrics the FDIC suite program now 1.6 billion, which for accounting purposes removes funds that would otherwise be included in our segregated cash balances on our balance sheet.

Securities lending interest income is lower this quarter as there were fewer of the highest rate hard to borrow lending opportunities in the market than in prior periods Now for our estimate of the impact of the next 25 basis point increase in rates with the continued growth in our customer assets, the investment opportunities available to us and new product introductions that were well positioned to maximize our net interest income and expectations to further rate increases are typically already reflected in the yields of the instruments in which we invest.

Therefore in our calculation, we attempt to isolate the impact of an unexpected rise in rates, separate from the impact of rate hikes that have already been baked into the prices of these instruments. With that assumption, we would expect the next 25 basis point unanticipated rise in rates to produce an additional $19.5 million in net income on customer balances over the next four quarters and $21.4 million as the yearly run rate. That run rate includes a reinvestment of all of our present holdings at the new higher rate.

Turning to the segments, Electronic Brokerage turned in a solid performance with gains in both commissions and net interest income. Net revenues were $444 million for the quarter up 21%. Pretax income was $292 million up 30% for a 66% pretax margin and treasury marks at $1 million were not material to segment results.

We received a $3 million clearing fee rebate this quarter versus $1.5 million in the year ago quarter are accounted for decreases in execution and clearing expense that it rebates the execution and clearing expenses would have been up about 1%. Fixed expenses in brokerage were $99 million up 14%.

The primary reason for this increase were that previously disclosed migration of expenses related to the winding down of market making also to increased legal and compliance expenses and also contributions to reserves.

Customer bad debt expense was a small gain this quarter reflecting immaterial new debts and our successful efforts to collect on some debts from prior periods. This is a demonstration of a continued effectiveness of our risk management systems and limiting customer defaults.

Market making continues to consist of customer facilitation activities and options market making in a small number of profitable markets outside the US at which we will operate for the time being as we continue to evaluate them.

Net revenues were $16 million of which $7 million were trading gains and the bulk of the remainder was net interest income. Market making pretax income was $7 million. We remain at about 95% of absorption of the $40 million of expenses that were projected to migrate to brokerage and we expect to reach full absorption in the fourth quarter.

The corporate segment reflects the effects of our currency diversification strategy. We carry our equity in proportion to a basket of 14 currencies we call it global to best reflect the international scope of our business. As the US dollar strengthened against most other major currencies this quarter, we incurred an overall loss from our strategy of $27 million of which $3 million is reported as other comprehensive income or OCI and $24 million is included in the earnings.

We estimate the total decrease in comprehensive earnings per share from these currency effects to be $0.06 with $0.05 reported in other income and $0.01 as OCI.

Turning to the income statement, net revenues of $439 million up 3% over the year ago quarter and adding back the $24 million loss on our currency strategy net of the $1 million gain from marking our treasury portfolio to market, results in adjusted net revenues of $462 million for the quarter, up 19% over last year's $388 million after adjusting for these items and also adjusting an $11 million gain on the sale of our U.S. market making business last year.

Commission revenue rose 2% on higher volume and options and as I mentioned before, higher DARTs and stocks partially offset by lower average trade sizes in most product categories.

As we noted earlier, the decline of our overall average cleared commission per DART to $2.78 reflected this mix. Of the $244 million net interest income, brokerage produced $235 million market making $7 and corporate the remainder.

Other income, which includes our global currency strategy, treasury marks and other fees and income we received was $21 million. Aside from the decline in the global in the absence of last year's one-time gain on the transfer of our US market making business, nearly all areas of other income showed increases.

Noninterest expenses were $163 million for the quarter, up 3% from last year and primary drivers were $10 million higher general administration expenses -- administrative expenses, largely stemming from legal and compliance costs and reserves. As a note, G&A expenses in the year ago quarter, contained a $3 million recovery of a tax reserve. So the increase would have been $7 million or 39% otherwise.

G&A increase was partially offset by lower execution and clearing expenses aided partly by the higher clearing fee rebate mentioned earlier as well as discontinuation of our US options market making business. Also acting to offset the increase were lower employee compensation and benefits expenses, which include regular adjustments to year-to-date budgeting for bonus accruals.

At quarter end, our total headcount stood at 1,380 up 15% from last year. We have been hiring most aggressively in the areas of client services, legal and compliance and software development and to this end, we continue to build up our operations in India.

Pretax income of $276 million was up 3% and represented 63% of pretax margin. Adjusted for the non-core items I mentioned previously, pretax income was $299 million up 29% over last year's pretax income of $231 million on an adjusted basis, representing an adjusted pretax margin of 65%.

Diluted earnings per share were $0.51 for the quarter versus $0.43 for the same period in 2017. Comprehensive diluted earnings per share, which includes all currency effects were $0.50 for the quarter versus $0.44 last year. Without the impact from currencies and treasury mark, diluted EPS would have been $0.56, so $0.05 higher than the reported EPS for the quarter.

To help investors better understand our earnings, the split between public shareholders and the non-controlling interest is as follows. First as a preface, the reclassification of one of our foreign entities resulted in additional reported one-time income tax expense $4 million and partially offsetting other income of $3 million.

These entries affect the public company only and they are similar to those we reported at year-end, which were related to the Tax Act. The additional tax is a non-cash item that affect our reported income only and not actual taxes paid.

So starting with income before income taxes of $276 million, we first deduct the $3 million of other income related only to the public company, leaving $273 million of operating companies income. We then deduct $6 million for mostly foreign income taxes paid by our operating companies.

That leads $267 million of which 82% or that $219 million reported on our income statement is attributable to non-controlling interest. The remaining 18% or $48 million is available for the public company shareholders, but as this is a non-GAAP measure, it's not reported on our income statement.

After we add back that $3 million of other income to the $48 million totaling $51 million and deduct the remaining taxes of $12 million, public company's net income available for common stockholders is the $39 million you see reported on our income statement.

The $12 million contains the one-time $4 million tax expense related to the reclassification I mentioned and that is without this item, the public company tax would have been $8 million.

Our income tax expense total of $18 million consists of this $12 million plus the $6 million of taxes paid by the operating companies. Turning to the balance sheet, it consistently remains highly liquid with low leverage or extremely well capitalized from a regulatory standpoint and we continue to deploy our equity capital on our growing brokerage business.

We hold excess capital in order to take advantage of opportunities as well as to emphasize the strength and depth of our balance sheet and we continue to carry no long term debt.

At September 30, margin debits were $30.7 billion, an increase of 22% over last year. Our compelling margin lending rates, which become increasingly noticeable versus our peers as the interest rates rise, plus our customer's willingness to take on leverage and Interactive Brokers capacity to satisfy it, have contributed to this growth.

This figure may show more swings than in past years due to our success in attracting institutional hedge fund customers or more opportunistic in taking on leverage. Our conservative balance sheet management supports a growing margin lending business.

Our consolidated equity capital at September 30, 2018, was $6.9 billion. $5.5 billion was held in brokerage. $1.1 billion in market making and customer facilitation activities and the remainder in corporate.

Now I'd like to turn the call back over to the moderator and we will be happy to take some questions.

[Operator]

[Operator Instructions] Our first question Rich Repetto from Sandler O'Neill. Your question please.

[Rich Repetto, Sandler O'Neill Partners]

Yeah good evening, Thomas. Good evening, Paul. The first question is on the growth rates, Thomas you can still report the highest growth in the industry, but if you look back compared to last year, it has moderated somewhat from the high 30%, 40% in growth year-over-year in equity and margin loan balances etcetera.

I guess I am trying to see is, is that as a growth bench again still tops in the industry, but has it been slowed by in any way Asia and what's going on in the Asian markets or could you attribute it -- what would you attribute to the change?

[Thomas Peterffy, Chairman & CEO]

So last year, the growth was higher because the markets went up and many of our customers were invested. So the assets, the value of their assets has increased. This year up to the end of September, our customer's total profit was only about $1.1 billion. So although this year were due to new assets.

[Rich Repetto, Sandler O'Neill Partners]

And then in the past, you broke -- you haven't quantified it, but you just said the fastest growing area was Asia. Is that still -- does that still hold true now?

[Thomas Peterffy, Chairman & CEO]

Yeah, that is still close to, yes.

[Rich Repetto, Sandler O'Neill Partners]

Okay. Thank you. And then the next question is on the shares per trade, we understand it's lower trading in the low priced stocks and you made up for nicely in proportion, people trading higher price stocks and with the commission, but I guess what we're not seeing is at least from what general text have been is other brokers being impacted in the low price -- trading at low priced stocks or have I got that wrong or…

[Thomas Peterffy, Chairman & CEO]

So if you remember, it was at June conference and I asked Chairman Clayton about whether the SEC is going to issue any clarification on their low price stock campaign. They are basically in strong words telling us that we shouldn't take customers who were being getting low priced stocks and when they sell it through us, unless we jump through several hoops, but they don't tell us what their hoops are.

So I asked him at that time whether they plan to clarify this and he said they are working on it. Why haven't they are saying yet. So we just tightened up on the circumstances under which we allow our customers who trade lower priced stocks.

[Rich Repetto, Sandler O'Neill Partners]

Okay. That I understand. Thank you. That's helpful, Thomas. Thanks. That's all I have.

[Operator]

Thank you. Our next question comes from the line of Kyle Voigt from KBW. Your question please.

[Kyle Voigt, KBW]

Hi. Just a couple questions on margin lending first, first just the sequential increase in the yield on customer margin at 26 basis points I think through the second consecutive quarter really outpaced our expectations. Just wondering if you're seeing some client mix within the margin balances that's been helpful to the overall yields?

I guess in another words, are a larger portion of the margin balance is coming from those lower balance and higher-priced tiers?

[Paul Brody, CFO]

Yeah, there wouldn't be any other explanation for that.

[Kyle Voigt, KBW]

Okay. And just a follow-up there, I know earlier this year you raised pricing on the upper tier margin balances by about five basis points and then in the press release you said at $30 billion as sort of a threshold or benchmark that you were monitoring previously.

Just curious now that margin balances have exceeded that $30 billion mark in September, are you comfortable with the level of customer margin that you have right now or will you continue to make some pricing adjustments?

[Thomas Peterffy, Chairman & CEO]

We are comfortable because credit balances have also risen in parallel.

[Kyle Voigt, KBW]

Okay. All right. Thanks. And last one for me is just on the -- you’ve launched a number of solutions over the past really year or 18 months that really seemed targeted at trying to increase your share of your clients wallet. So there is integrated investment management offering but a debit card in direct deposit.

I am just wondering some fees have been rolled out, do you think that you're having success in increasing that share of wallet and other metrics that you track internally and I guess that that would suggest that you're having success there, thanks?

[Thomas Peterffy, Chairman & CEO]

Well as we say, we have roughly $61 billion of cash, which is more than a third of all of our assets. So I wouldn’t know how to describe it but to the high interest that we are paying.

[Kyle Voigt, KBW]

Okay. All right. Thanks.

[Operator]

Thank you. Our next question comes from the line of Mac Sykes from Gabelli. Your question please.

[Mac Sykes, Gabelli & Co.]

Good afternoon, everyone. I did appreciate Nancy's comments on the free trading and your initiatives there, but maybe you could talk a little bit more about this topic of free trading seems like some of the customer agreements from some of your competitors actually have hidden costs in them. And I just want to get your thoughts on sort of advertising, free trading and whether that's truly the case?

And then secondly, if you’ve gotten any feedback from your customers given that you are low-cost offering in terms of customer feedback around free trading and obviously complaints or just questions around that and what you may be doing about it?

[Thomas Peterffy, Chairman & CEO]

So this is a serious issue for us now that JPMorgan joined Robin Hood offering free trades. We have to take this very seriously as I said. So we are currently working on commercial to explain to people why that is bad for them, but the fact is that if you look at our ACATs for example, we regularly gain customers, two, three, four customers a day from Robin Hood and I've never seen a customer who went from us to Robin Hood.

[Mac Sykes, Gabelli & Co.]

Okay. And you talked a little bit about market reform on the small cap stocks, but could you just talk about maybe market reform in terms of make or take a model going forward on your partnership with Value [ph] and where you see that may be changing over the next five years or so?

[Thomas Peterffy, Chairman & CEO]

Mac, we have no idea what is going to happen. I really don't know. It's hard to get anything from the SEC and the indication of any -- they must very busy because we are more successful in trying to talk to them about anything.

[Mac Sykes, Gabelli & Co.]

Okay. Thank you for the questions.

[Operator]

Thank you. Our next question comes from the line of Chris Harris from Wells Fargo. Your question please.

[Chris Harris, Wells Fargo]

Thanks. I just wanted to follow back up on the point about industry of the cuts pricing pressures, are you getting inquiries from customers about JPMorgan about Robin Hood and it sounds great that nobody is transferring out…

[Thomas Peterffy, Chairman & CEO]

We have not heard, no one has asked us anything -- we have been more sophisticated customer base. They understand what goes on there. So, I mean -- you know they -- we always tell them how much money, the brokers earn in payments for order flow and they understand where that comes from.

[Chris Harris, Wells Fargo]

Got it. Okay.

[Thomas Peterffy, Chairman & CEO]

I was saying could you do my trades commission free, no that has not happened.

[Chris Harris, Wells Fargo]

Okay. And then you clearly have a well-documented value proposition. It sounds like your customers get it. I just want to clarify that point. Okay another topic in terms of interest earning asset balances. You got the FDIC sweep program now and I am wondering if you guys have thought internally about what the opportunities for that could potentially be?

How many of your customers do you think might want to take advantage of that program? I know its early days, but probably guys get pretty nice economics there? So maybe you could elaborate on that if you could for us?

[Thomas Peterffy, Chairman & CEO]

Paul, we do have that?

[Paul Brody, CFO]

Yeah sure. So we began to roll it out last -- the fourth quarter of last year and we fairly quickly made it available to the various customer groups who would be eligible for it where we haven’t quite covered them all.

We estimate that if we had full participation maybe the balances would be probably little more than double what they are. So we got pretty good take up on it right now. So we're happy with it. Our own earnings are at or maybe a little better than our other investment rates now that other investment rates at banks without taking advantage of the yield curve of course.

So it's operating quite well. We're happy with it at the level of that. We think it grows steadily as customers pick up on it and I think new customers we made efforts to present it to them fairly on their way in. So there's probably a more take up there than it was before and it's a good program.

[Chris Harris, Wells Fargo]

Okay. Great. Thank you very much.

[Operator]

Thank you. Our next question comes from the line of Brian Perry from Reed [ph] Street. Your question please.

[Unidentified Analyst]

Hey. Good afternoon and thanks for taking my questions. First question is a follow-up on Rich's remarks about trading activity and low priced shares. I am wondering if you could give a little more color on what types of operational changes you made to achieve the curtailment of trading in low priced shares among your existing customers and for this quarter just approximately what impact you think that curtailment had on your DARTs? Thank you.

[Thomas Peterffy, Chairman & CEO]

So we have -- our compliance department issued new regulations which we use internally that strictly describes what kind of trades we can and cannot accept, what kind of orders we can accept and what kind of orders we cannot accept.

The upset on the part of customers was substantial. There is nothing that we will do about that and if they don't like it, we are sorry, but we cannot have them -- a number of them have gone to look for other brokers and that's all I can tell you.

So I did not do the work to figure out how many low-priced stock trades we have lost per day for example. Have you Paul? You had some.

[Paul Brody, CFO]

I don't have detail at that level. No.

[Unidentified Analyst]

Got it. I mean the reason I was asking was volatility was up almost 18% year-over-year and your account growth is in mid-20s with DARTs growth of just about 10%. I'm wondering if there's any way to -- it's in effect that you will probably lap in a year I'm guessing and so interest in any way to ballpark that affect that you will presumably lap in, I don't know, nine months or something.

[Thomas Peterffy, Chairman & CEO]

Well I'm sorry. I do not think that -- I think that a greater impact that is coming from the fact that more of our new accounts are introducing broker accounts and those accounts tend to trade less than our original customer base which is the sophisticated traders.

When we started the business, we originally addressed ourselves to floor traders and people who were trading for a living right. So that's why we still have our basic customer -- customary still there, that that's where all of the bulk of our volumes come from, but those people are getting old, as I know.

[Unidentified Analyst]

Yes. I appreciate the color and second question if I could, so customer credits represented about 36% of our customer equity in this quarter and that's inclusive of sweeps. I'm wondering how different that number looks for your new customers for incoming assets?

[Paul Brody, CFO]

I don't we measure it separately for the incoming customers, but you have to understand and perhaps not put too much weight on the credit number itself because as I mentioned before in my talk that we've got a very steady stream of customer money and asset transfers coming in all the time.

But the credit balances are subject to what happens to them after that. So they become invested depending on how are the markets doing and their customers actually become more or less invested in stocks, that's one primary factor.

Certainly on an aggregate basis for us as a broker, we take customer credits and limit it to other customers who are doing secured margin lending and that has certainly gone up quite rapidly. So that leaves us with less to invest on the street, but customer credits are still going up.

So all of these factors contribute to -- obviously lay off work their way into the net interest margin in one way or another, but you have to understand about the customers being invested in the market, which is certainly not under our control.

[Unidentified Analyst]

Got it. And it sound like it's not a number you track or have the ability to track. It’s just the point you made. It's a really important input in projecting what net interest income will grow at over the longer term is just how intense new clients are in terms of their cash balance.

[Thomas Peterffy, Chairman & CEO]

Yeah but you have to remember that these clients, at least the ones that had more $100,000 with us got as it's worth of assets with us are getting paid interest and so we will be airing on these balances is had some.

[Unidentified Analyst]

Yes. I mean it adds up, it's like larger than your commission revenue now. Okay. Thanks for the color. I do appreciate it.

[Operator]

Thank you. [Operator Instructions] Our next question is a follow-up from the line of Mac Sykes from Gabelli. Your question please.

[Mac Sykes, Gabelli & Co.]

Oh hi. Wanted to just dig into if I were to have say $100,000 account at the firm fully invested in S&P securities, how much I would hope to make just on the collateral that could be used for the portfolio.

[Paul Brody, CFO]

So it's interesting that you picked S&P securities because they tend to be what we would call general collateral meaning Blue Chips and fairly uninteresting from a lending standpoint as far as the demand on the street.

If you have picked another index that had more what we call hard to borrow stocks, you know more esoteric as names, more stocks in greater demand, you could certainly see substantial earnings from participating in the fully paid lending program.

And those numbers are all over the lot, and they come and go. That's why the securities lending revenue is very much a function of which -- in which stocks get hot at certain times. We've seen Tesla come and go sort of in terms of its demand for shares on the street as it's one name and our job is as we have built tools to take advantage and optimize the lending when these stocks go into a range where their rates get very high.

[Mac Sykes, Gabelli & Co.]

And just to clarify on GC, what was the yield I guess, are their earnings.

[Thomas Peterffy, Chairman & CEO]

There is no yield on GC.

[Paul Brody, CFO]

Right. We don't even want that GC because it doesn't produce any yield, but if you were a customer, I can tell you that you can look into a report that we would deliver to you that would tell you what the indicated earnings would be on the portfolio that you actually hold in your account to try to interest your feelings getting to see what the value of participating in a program might be.

So we had very good participation in the program because we do a good job of lending shares out.

[Mac Sykes, Gabelli & Co.]

Okay. Great. Thank you.

[Operator]

Thank you. This does conclude the question-and-answer session of today's program. I'd like to hand the program back to Nancy Stuebe for any further remarks.
