Excellent. Well, thank you very much, Walt. So you all heard Walt and Rick talk about the continued success we're having winning clients in spite of somewhat more subdued investor sentiment and engagement; the progress we're making in bringing new solutions to our clients and advancing our strategic priorities; and finally, about the huge opportunity we have to broaden our moat and continue to drive strong organic growth.
In my time today, I want to talk about how our all-weather business model helped us produce results. They were off last year's record level but still quite strong considering the various headwinds we faced. I'll discuss our evolving investment management thinking and how we're positioned to benefit significantly if the Fed hikes rates as expected.
And finally, I'll provide an update on our capital management approach moving forward. The message you should hear is that regardless of how someone might have viewed our recent quarter's financial results, our Through Clients' Eyes strategy is working and our business model is working, producing strong financial performance with the potential for an acceleration of revenue growth in the quarters ahead should the Fed follow through on their tightening cycle.
So let's talk about some of the cross-currents that influenced our financial performance in the first quarter. At our winter business update a few months ago, we highlighted some of the questions that would shape our operating and financial performance in 2022. As Walt talked about, the quarter was a challenging one for our clients and investors in general.
As we look at the quarter from the context of our business model, some of the developments have been helpful: the decline in COVID cases, clearly; the rise in long-term interest rates; and continued robust trading activity. While others have presented challenges, specifically rapidly rising inflation; a Fed funds rate, which, of course, is expected to rise dramatically over the next several quarters, but which remain near 0 for most of the quarter; a decline in equity markets that Walt referenced; and a less exuberant attitude among investors in general and our clients in particular.
Now despite some of those challenging dynamics, we were able to deliver financial performance that was a bit below last year's record level but still quite solid. As we said previously, with the acquisition of Ameritrade, we are more exposed to dynamics that can fluctuate in less predictable ways: trading behavior, margin utilization and securities lending to name a few. In Q1, the risk off sentiment among clients impacted all these drivers and weighed on our results, resulting in revenue that was down 1% from the unprecedented Q1 of 2021. Now we limited growth in adjusted expenses to 4% year-over-year, which produced an adjusted pretax margin close to 45%, a 26% return on tangible common equity and $0.77 of adjusted EPS.
Comparing conditions to the financial scenario we shared in January. The equity market decline has obviously been a negative while the Fed hiked in March consistent with our scenario. Trading activity was a bit higher than the scenario contemplated. But as we'll discuss in a moment, as Walt previewed, the mix of trades was different than what we saw last year, which produced lower revenue per trade.
The scenario seemed consistent securities lending revenue and margin utilization, but both were down from the fourth quarter, 20% in the case of sec lending, which, of course, adversely impacted our net interest margin and revenue. And balance sheet growth tracked a little higher than contemplated in this scenario given the strong asset gathering and somewhat lower net purchase activity by clients.
It's always a little tricky comparing results for a single quarter with a scenario that covers the full year, especially given the assumption in the January scenario for 2 more rate hikes in 2022, which should increase revenue growth and pretax margins in subsequent quarters. But our financial results thus far have been pretty close to what the scenario anticipated for the first quarter.
And on the expense side, our results were very much consistent with our financial plan, meaning that we're sticking with our expectation for full year adjusted expense growth of 6% to 7%, excluding, of course, any variation based on our bonus funding.
I mentioned earlier that even as overall trading activity has remained quite robust. We have seen some changes in the types of trades being made, which on balance have reduced the revenue per trade versus the fourth quarter as we previewed in the commentary attached to our February SMART report.
Our RIA clients are being relatively more active. And while derivatives continue to account for 23% of total trades, we're seeing an increase in futures trades as well as options activity on indices relative to individual equities. We also saw a decline in the size of the average options trade. So all these factors taken together combined to lower revenue per trade by roughly 10% versus the fourth quarter of 2021.
It's too early, of course, to know whether this mix shift is an anomaly or a trend, but we're certainly glad our platform can meet a broad and sometimes varying range of needs across retail and RIA clients, equities, futures and options, small and large trades.
Turning our attention to the balance sheet. Our balance sheet grew another 2% sequentially driven by more than $20 billion increase in bank deposits due to strong asset gathering and our migration of $12 billion or $13 billion in cash out of the IDA.
Within our interest-earning assets, the decline in equity markets prompted a decline in margin utilization. While we're continuing to be very successful in increasing adoption of our compelling bank lending solutions with balances up another $2.5 billion in the quarter and 46% over the last 12 months. We're active on the financing front, issuing $3 billion of debt to supplement parent liquidity and $700 million in preferred to support the balance sheet growth we've experienced.
Stockholders' equity declined due to mark-to-market unrealized losses on our AFS or available-for-sale portfolio due to higher interest rates. This is a good moment to remind you all that we moved approximately $111 billion of securities from AFS to held to maturity at the end of January, insulating from AOCI further changes in their unrealized gain loss. Now the loss at the time of that transition was $2.4 billion, which will amortize as those securities mature. And that negative AOCI does not impact regulatory capital. So our consolidated Tier 1 leverage ratio remained just north of 6%.
As I mentioned earlier, our financial performance was helped only modestly this quarter by the increase in interest rates to start the year. But going forward, that should change with Schwab poised to see tremendous lift should the Fed pursue what is expected to be a dramatic increase in rates. The path of our net interest margin will always depend on how rates ultimately trend as well as how our clients manage their cash, how we manage our investment portfolio and of course the level of the securities lending revenue and margin utilization.
Now as you saw in our earnings release, our net interest margin decreased 6 basis points sequentially from the fourth quarter of 2021 to the first quarter of 2022. That decrease was entirely due to a lower contribution from securities lending and margin utilization as well as an increased allocation of cash, which more than offset a 7 basis point sequential improvement in the yield on our investment portfolio.
Looking forward, if the Fed hikes rates to a range of 2.25% to 2.5% by the end of the year, as the market currently expects, we could see our net interest margin climb to the mid-1.80s in Q4. So while our NIM declined in Q1, the upside to higher rates still very much exists.
So now let's talk about some of the factors that influence our NIM trajectory. The most important factor, of course, is what ultimately happens with rates. We talk a lot, both Rick and Walt referenced, our Through Clients' Eyes strategy and we talk about it in the context of our business priorities and approach. But we also adopt a similar lens in our investment approach. And what I mean by that is that we don't change our investment strategy based off our own in-house view of what is going to happen with rates in the future. Instead, we take market expectations as an input and then adjust our investment strategy based on how we think clients might respond, which ultimately influence our liability duration, our liquidity planning to support the client behavior and deposit pricing.
Over time, the amount of cash our clients hold tends to grow with the growth in accounts and the growth in total client assets and how much of that cash sits on our balance sheet, primarily in our bank sweep and broker-dealer free credit products. Well, that varies based off the level of primarily short-term interest rates. When the Fed funds rate increases, solutions like purchase money funds and CDs are able to offer more meaningful yields. So clients tend to move more of their so-called investment cash off our balance sheet into these higher-yielding alternatives. It's what we've called client cash sorting.
Now in 2015 to 2019, the client cash sorting produced a roughly 20% reduction in uninvested or sweep cash balances over a 3-year period once the Fed started tightening until those balances resumed growing again. Now assuming the Fed follows through as expected, we would expect that process to return. The 2015 to 2019 period is a reasonable reference point for our expectations this cycle, but there are a number of different dynamics this time around that could influence that behavior.
At the same time, we'd expect to see continued growth in bank lending, as Rick discussed, as we improve the PAL process, make our lending solutions available to legacy Ameritrade clients and continue to increase awareness of our very competitive mortgage rates. And given the way the LCR, or liquidity coverage ratio, calculation works, we need to maintain stable or even growing free credit balances within the broker-dealers to support our margin book. So any sorting that happens there needs to be replaced by transferring balances out of bank sweep.
Now with higher rates, we'd also expect paydowns to slow. Now we have plenty of liquid assets and borrowing capacity to support outflows. But we'd rather not sell assets potentially at a loss or have to rely on higher-cost FHLB borrowing on a long-term basis. So we need to ensure we have enough liquidity at the banks to enable these client cash allocation changes without selling securities or borrowing from the FHLB.
Our investment portfolio in aggregate looks pretty similar to how it looked 1 year ago with a fixed floating allocation of 90-10 and a duration around 4.7. But those numbers are higher than in 2015, which means that the upside from higher rates is very much still there, though the benefit will accrue to us over a longer period of time than the last rising rate cycle.
We are, however, carrying more cash in the portfolio. 15% or 16% versus our typical 5% to 7% level. This decision to hold more cash wasn't about market timing. Though in hindsight, it was good we didn't deploy the cash earlier in the quarter when rates were much lower than where they are now. But it does give us more flexibility and increases our upside to higher rates.
We're also repositioning the portfolio and targeting our investments to ensure we have a lot of maturities in the next 2 to 3 years. And while the yield curve is quite flat, we are sacrificing some amount of current net interest revenue to maintain this higher level of liquidity. But I emphasize current because this is just a timing difference. If the Fed follows through its plan that the yield trade-off will decrease steadily and this approach obviously increases our asset sensitivity and upside to higher rates.
As we look to the future, we would expect deposit betas to be no higher than they were during the last rising rate cycle. And that is a function of our cash strategy through which we offer our clients access to higher-yielding cash alternatives within their brokerage accounts for their investment cash, allowing us in our flagship bank suite product, which is the repository of what we call transaction cash or cash awaiting investment to offer a yield that is somewhat lower, but still quite compelling relative to the checking account rates offered by the big banks.
And finally, a word or two on capital. With the continued growth on our balance sheet, our consolidated Tier 1 leverage ratio declined slightly to 6.1%, below our operating objective but well above the regulatory minimum. I've read some commentary on our negative AOCI mark and the potential impact that could have on our regulatory capital. As a reminder, for some of you who may be less familiar with the issues involved, mark-to-market gains and losses in our AFS portfolio do not flow through the P&L, but do impact stockholders' equity through a line item called accumulated other comprehensive income, or AOCI.
Now as a Category 3 institution below $700 billion in assets, we have the option, which we have taken, to exclude AOCI from our regulatory capital ratios. As of 3/31, AOCI was negative $11 billion. But again, that doesn't impact our regulatory capital. It will only do so if and when we cross $700 billion in assets and stay there for 4 consecutive quarters. And while we are close to that level today, the client cash sorting that should accompany higher rates will mean a slowing or even reversal of balance sheet growth, which means we may not hit that trigger for some time. At which point that AOCI mark will have amortized down somewhat.
So what that means is higher rates mean that the $700 billion threshold gets pushed out, while lower rates mean that the negative AOCI gets reduced. Either way, we see this as something that is quite manageable.
Let me close with a few thoughts. It's obviously been a turbulent week for the stock, as Walt referenced and frankly, a turbulent start to the year. And we're cognizant of the impact that has on all of you, our owners. At the same time, we continue to focus on the things that we can control. And the measures that we look at as indicators of the value of the business have stayed remarkably consistent: organic growth, whether measured by net new assets or new accounts; our Net Promoter Score or what we call Client Promoter Scores, which have reached new highs despite the market turbulence; our TOA ratio and the wins we see from competitors; and the progress we're making on our strategic agenda. Those are the most important barometers regarding the health of the business and are all giving us confidence that we're on the right track.
With that, Jeff, let me turn it over to you to facilitate our Q&A. Thanks.
