This article answers the most common questions about how Rho Treasury works, including where your assets are held, how fees are calculated, what tax forms to expect, and how to protect your funds. For step-by-step instructions on setting up and managing your account, see Managing your Rho Treasury account . General Is Treasury a bank account? No. Rho Treasury is an investment account, not a bank account. Your cash is invested in short-duration securities – T-Bills, MULSX, and/or VFSTX / VFSUX – and, if you are enrolled in the money market fund sweep, swept into IJTXX. These holdings are held directly in your company's name at our custodial partner, Apex Clearing Corporation. Treasury assets are not deposits and are not FDIC-insured. Treasury assets held at Apex Clearing Corporation are covered by Securities Investor Protection Corporation (SIPC) insurance up to $500,000 (including a $250,000 limit for cash). What assets can I hold in Rho Treasury? Rho Treasury supports four assets, which you can hold simultaneously in any combination: IJTXX – JPMorgan U.S. Treasury Plus Money Market Fund. A money market fund offered as a cash sweep with same-day liquidity. Best for cash you may need on short notice. Visit our helpful article to learn more about the IJTXX MMF sweep. T-Bills (13-week) – U.S. government-backed securities. Suitable for cash you won't need for at least 3 months. MULSX – Morgan Stanley Ultra-Short Income Fund. Suitable for cash you won't need for 4 to 6 months. VFSTX / VFSUX – Vanguard Short-Term Investment-Grade Fund (Investor or Admiral Shares). Suitable for cash you won't need for at least a year. Closed to new investments. Note: The Vanguard fund is closed to new investments . If your account already holds Vanguard (VFSTX or VFSUX), any change you make to your portfolio caps Vanguard at 35%. If you hold more than 35% today, a change sells the extra shares at the current market price, and this sale can realize a loss. This limit reflects the fund's longer time horizon. It is best suited for cash you won't need for at least 12 months, not operating capital. Contact the Rho team if you need a higher limit or have questions. Why can’t I see VFSUX or the IJTXX MMF sweep? VFSUX and the IJTXX money market fund sweep are available through Apex Ascend, our new custody platform. If you joined Rho Treasury on or after July 23, 2026, your account is on Ascend, and both options are available to you. If you joined before July 23, your account will migrate to Ascend in the coming months. These options will become available once your migration is complete. Please contact us with any questions about the migration. What is VFSUX, and what happens to my VFSTX investment? Note: VFSUX and VFSTX are currently closed to new investments in Rho Treasury. Learn more about why here . VFSUX and VFSTX are share classes of the same Vanguard Short-Term Investment-Grade Fund. They invest in the same underlying portfolio, but VFSUX, the Admiral Shares class, has a lower expense ratio. VFSUX is now the only Vanguard fund available for new allocations. If you already hold VFSTX, you will continue holding it. Here’s what to expect: Your existing VFSTX investment stays as is. We will not sell it automatically, and there is no deadline to move it. New money is invested in VFSUX. You will continue to receive dividends on your VFSTX position. Those dividends, along with new deposits and interest, will be invested in VFSUX rather than VFSTX going forward. Your Vanguard allocation will appear across both funds. You will continue to set one Vanguard target in the ‘Edit Portfolio’ flow. Your ‘Portfolio’ tab will show separate VFSTX and VFSUX positions that together make up your Vanguard allocation. VFSTX is sold before VFSUX. When a withdrawal or rebalance requires us to sell from your Vanguard allocation, we sell shares on a first-in, first-out basis (FIFO). Because your VFSTX shares are older, they are sold first. Over time, your VFSTX balance will decrease while your VFSUX balance grows. VFSTX disappears when its balance reaches $0.00. It will no longer appear in your portfolio, and your full Vanguard allocation will appear as VFSUX. Your previous VFSTX transactions will remain in your Activity history. The 35% limit applies to both funds combined. Your total VFSTX and VFSUX allocation is limited to 35% of your portfolio. Existing allocations above 35% can remain in place. However, before submitting any portfolio changes, you will need to reduce your combined Vanguard target to 35% or less unless we have approved a higher limit for your account. You don’t need to take any action. If you prefer to move your entire VFSTX position to VFSUX now, contact the Rho team. Because the switch requires selling your VFSTX shares, it may result in a taxable gain or loss. Consult your tax advisor about your specific situation. Are my assets pooled with those of other clients? No. Securities are held directly in your business's name and are not pooled with other clients' assets. Who can move funds in and out of my Treasury account? Funds can only be transferred to and from your Rho Checking account by individuals you have authorized in your Rho account settings, or through auto-transfer rules you have configured. Read more on auto-transfer rules here . Eligibility and setup What information is required to apply? Applying for Treasury requires standard KYC information including SSN//TIN/Passport/EIN. You may also be asked to provide formation documents, a business license, a certificate of good standing, and beneficial ownership and authorization forms. How do I know if I’m eligible for an account? If you’re eligible, go to the Treasury tab in your Rho dashboard and follow the steps to apply. The application takes less than 10 minutes, and approval typically takes up to 2 business days. If you don’t see the Treasury page but believe you're eligible, contact our Client Services team. Read more on eligibility requirements here . Can I give my accountant access to my Treasury account? Yes. You can set your accountant up with read-only access to your Treasury account. They will be able to view your monthly statements, trade confirmations, and tax documents. Can I close my Treasury account? Yes, at any time, by contacting Rho. Closing requires liquidating all holdings, which typically takes 2-3 business days. Assets sold during closure are sold at current market prices and may lose value compared to your original investment. Protection and insurance What protection do I have on my Treasury assets? Treasury assets held at Apex Clearing Corporation are covered by Securities Investor Protection Corporation (SIPC) insurance up to $500,000 (including a $250,000 limit for cash). SIPC protects against the loss of assets in the event of a brokerage failure – it does not protect against the decline in value of your securities. Are Treasury assets FDIC-insured? No. Treasury assets are securities, not bank deposits, and are not FDIC-insured. T-Bills are backed by the full faith and credit of the U.S. government. MULSX and VFSTX / VFSUX are mutual funds with variable NAVs, so their share prices move with interest rates and the market. IJTXX is a government money market fund that seeks to hold its share price at $1.00. You could still lose money by investing in it. The fund cannot guarantee it will maintain a $1.00 share price, and an investment in the fund is not insured or guaranteed by the FDIC. For FDIC-insured coverage, see Rho Checking accounts. Yield and fees What does Rho Treasury cost? Rho Treasury charges an annualized management fee of 0.15%–0.60%, billed monthly. Your fee tier is based on your total assets under management (AUM). Learn more about AUM-based fees here . Total AUM Annual fee > $20M 0.15% (15 bps) $10M-$20M 0.25% (25 bps) $5M-$10M 0.35% (35 bps) $2M-$5M 0.45% (45 bps) Under $2M 0.60% (60 bps) Is the yield shown on my dashboard before or after fees? The yield shown on your Treasury dashboard is net of fees. It already reflects the management fee deducted. Hover over the (ℹ) icon to see your annual management fee percentage. Tax and reporting What tax forms will I receive? Depending on your entity type and activity, Apex may generate a 1099 tax form. Absent an extension, Apex is required to deliver these forms to the account holder by the regulatory due date. All tax forms will be emailed to the account holder from rho@tax-docs.com and uploaded to Rho’s document section. Why didn't I receive a 1099? If your activity did not meet IRS reporting thresholds, a 1099 will not be issued. Thresholds are $10 for dividends and interest, $20 for cash in lieu, and $600 for miscellaneous income. Additionally, C corporations are generally exempt from 1099 reporting under IRS broker reporting rules. Not receiving a 1099 does not mean your income is non-taxable. Consult your CPA. Are T-Bill returns subject to state tax? Interest earned on T-Bills is subject to federal income tax but is exempt from state and local income taxes. Fund distributions from IJTXX, MULSX, and VFSTX / VFSUX may include a portion of income exempt from state tax, depending on each fund's government securities holdings. Each fund publishes its own figures after year end. Consult your CPA for details. How do I get my statements for tax purposes? Go to Settings → Account Statements → Treasury Account to download trade confirmations, monthly or quarterly statements, and tax documents. Your CPA can use full-year statements (January 1 – December 31) to prepare your return. When are statements generated? Monthly statements are generated for accounts with deposits, withdrawals, or trades in that month. Dividends and interest payments do not trigger a monthly statement. Accounts without qualifying activity receive a combined quarterly statement instead. How does Rho Treasury affect QSBS eligibility? Rho does not manage accounts for Qualified Small Business Stock (QSBS) eligibility or compliance, and clients should consult with their CPA or tax advisor to ensure all applicable QSBS requirements are properly met. For a deeper dive, read our blog post on QSBS . Custody & account management Where is my money custodied? Your funds are held in your company's name at Apex Clearing Corporation, Rho’s custody provider. Can I transfer my Treasury holdings to another brokerage via ACAT? Yes. ACAT transfers are initiated by the receiving brokerage. Note that once an ACAT transfer is initiated, you will be unable to add or withdraw funds for up to 90 days. Your holdings will continue earning returns during that period. Because transfers are initiated externally, Rho's ability to support issues related to the transfer may be limited.

How the IJTXX money market fund sweep works in Rho Treasury, including same-day liquidity, dividends, and fund information. Overview Rho Treasury gives you access to four assets: the IJTXX money market fund sweep, T-Bills, MULSX, and VFSUX. Funds allocated to the sweep are held in your company's name at Apex Clearing Corporation and invested in the JPMorgan U.S. Treasury Money Market Fund (IJTXX) , Institutional Share Class. Money market funds are mutual funds that invest in highly liquid, short-term assets that generally carry relatively low risk. Government money market funds invest at least 99.5% of their assets in cash, government securities, or repurchase agreements collateralized by either. IJTXX is a government money market fund that invests only in U.S. Treasury securities and repurchase agreements backed by them. The fund seeks to maintain a stable share price of $1.00. IJTXX is offered as a cash sweep, so you do not buy or sell it directly. Apex automatically moves your allocated cash into the fund at the end of each business day. In your Rho dashboard, IJTXX appears as an asset with its own balance, yield, and allocation. IJTXX is the only Rho Treasury asset with same-day settlement. Fund details View the fund page or summary prospectus for performance, current yield, holdings, and other fund details. You can also find this information on the J.P. Morgan Asset Management website. Why can’t I see VFSUX or the IJTXX MMF sweep? VFSUX and the IJTXX money market fund sweep are available through Apex Ascend, our new custody platform. If you joined Rho Treasury on or after July 23, 2026, your account is on Ascend, and both options are available to you. If you joined before July 23, your account will migrate to Ascend in the coming months. These options will become available once your migration is complete. Please contact us with any questions about the migration. Using the money market fund sweep Enroll in the sweep Before IJTXX is activated, you must accept the sweep terms and choose to invest idle cash in the fund, automatically. New Treasury accounts: accept the sweep term agreement at onboarding. Existing Treasury accounts: accept the one-time prompt in the Treasury dashboard. If you decline, the sweep will remain off and you cannot allocate funds to IJTXX. You can enroll later. We will show the terms again when you add IJTXX in the ‘Edit Portfolio’ flow. To unenroll from the sweep, contact Rho . Once the sweep is turned off, uninvested funds will remain in your Treasury account as cash. Set your allocation IJTXX follows similar allocation rules as the other Rho Treasury assets: Set allocations in 5% increments Make sure your total portfolio allocation equals 100% Allocate at least 5% to IJTXX if you include it Allocate up to 100% to IJTXX Buy or redeem any amount, with no minimum Any cash remaining after portfolio-based asset purchases or sales is swept into IJTXX. Before investing, carefully consider the fund's investment objectives, risks, charges, and expenses. The fund invests in U.S. government securities and repurchase agreements collateralized by those securities. It aims to preserve capital, provide liquidity, and earn yield on idle cash. To set or change your IJTXX allocation, go to Treasury → Edit Portfolio . Access funds same day IJTXX is the only Rho Treasury asset with same-day settlement. When you request a withdrawal When funds arrive Before 3:00 PM ET on a business day Same business day After 3:00 PM ET on a business day 1-2 business days On a weekend or market holiday 1-2 business days Your Treasury dashboard shows available same day balance – the amount you can move to your Rho Checking account that day. It includes your IJTXX balance and any uninvested cash. All other Treasury assets take at least one business day to settle. T-Bills settle the next business day. MULSX and VFSUX settle in one to two business days. Withdrawing The source of your withdrawal depends on the amount you request and your IJTXX balance. If the withdrawal is equal to or less than your IJTXX balance: Rho redeems the full amount from IJTXX. If you request before 3:00 PM ET on a business day, funds arrive in your Rho Checking account that day. If you request after 3:00 PM ET on a business day, funds arrive in your Rho Checking account the next day. If the withdrawal exceeds your IJTXX balance: Rho sells the full amount from your other assets instead. T-Bills, MULSX, and VFSUX are sold proportionally based on your current allocation. Your IJTXX balance remains available for same-day withdrawals. Standard settlement times apply. Rho does not split a withdrawal between IJTXX and your other assets, and you cannot choose which assets to sell. Example: Your portfolio holds 20% in IJTXX ($20,000) and 80% in MULSX ($80,000). Withdrawal request Funded from Funds arrive $15,000 at 11:00 AM ET on Tuesday IJTXX Tuesday $15,000 at 4:00 PM ET on Tuesday IJTXX Wednesday $30,000 at 11:00 AM ET on Tuesday MULSX; IJTXX remains unchanged By Thursday morning If you expect to need cash on short notice, increase your IJTXX allocation in advance. How IJTXX works with auto-transfer rules Auto-transfer rules move funds between your Rho Checking and Treasury accounts automatically, so your operating account stays funded without manual transfers. For rule types and setup steps, see Setting up auto-transfer rules . Transfer rules follow the same withdrawal logic as regular transfers. See above for an example. Replenishing your IJTXX balance Withdrawals reduce your IJTXX balance. Incoming funds replenish IJTXX first. Deposits, T-Bill maturity proceeds, fund dividends, and cash interest bring IJTXX back to its target allocation first. Rho then invests any remaining funds proportionally across your other assets. IJTXX dividends IJTXX dividends accrue daily and are paid monthly. Dividends are paid on the first business day of each month. If the first falls on a weekend or market holiday, payment arrives on the next business day. Your dividend appears in Treasury → Activity on the day it is paid, and is included in the realized P&L value shown in your Treasury overview. Like all Treasury earnings, it is automatically reinvested according to your target allocation, with IJTXX replenished first.

Auto-transfer rules move funds between your Rho Checking and Treasury accounts based on a schedule and/or a balance threshold you define.This article explains the available rule types, how to set them up, and how they work. What are auto-transfer rules? Auto-transfer rules automatically move funds between your Rho Checking and Treasury accounts based on a schedule and/or balance threshold you define. You can create two types of rules: Recurring transfers Move a fixed amount between accounts on a schedule you choose: daily, weekly, monthly, or custom dates. Maintain balance rules Automatically move funds when your account balance crosses a threshold you set. Choose one of the following: Minimum balance – transfer funds into an account when its balance falls below your target Maximum balance – sweep excess funds out of an account when its balance exceeds your target $0 balance – sweep the full available balance out of an account Maintain balance rules can run two ways. Choose Schedule to have funds arrive on dates you select, or Balance change to have Rho check your balance after every transaction and transfer as soon as your threshold is crossed. Set up an auto-transfer rule Go to All Accounts > Auto-transfer rules > Add rule . Choose a rule type. Select your source and destination accounts. Configure the amount or balance threshold, then choose whether the rule runs on a Schedule or on Balance change Click Create rule . Your rule becomes active immediately. After a rule is created, the source and destination accounts can't be changed. To use different accounts, delete the rule and create a new one. You can edit the amount and cadence at any time. How auto-transfer rules work Treasury rules don't run on weekends or market holidays. If a scheduled run falls on one of those days, it runs on the previous applicable business day unless otherwise noted. Recurring transfers Recurring transfers settle on the date you select. That date is the settlement date, not the date the transfer is initiated: Rho initiates the transfer early enough for funds to settle when you need them. Recurring transfers are evaluated at 8:00 a.m. ET. Maintain balance rules Maintain balance rules run in one of two modes, which you choose when creating or editing the rule. Schedule: Rho evaluates your balance at 8:00 a.m. ET on business days. If your balance falls outside the threshold, Rho schedules a transfer to settle on your configured arrival date. As with recurring transfers, the date you select is the settlement date, not the initiation date. Balance change: Rho checks your balance after every settled transaction. When your threshold is crossed, a transfer starts that business day. There is no date to select. Transfers from Treasury still take up to three business days to settle. How transfer dates work Transfer direction Date you select How it works Checking → Checking Settlement date Transfer settles on the selected date. Treasury → Checking Settlement date Rho initiates the transfer 3 business days before settlement and adjusts earlier for weekends and market holidays. The date you select is the settlement date. Rho initiates the transfer in advance so your funds arrive on that date. Maintain a minimum balance in Checking by transferring from Treasury This is the most common rule for customers using Treasury. It helps keep your Checking account funded for payroll, vendor payments, and day-to-day operations. On a schedule Treasury liquidations can take up to three business days to settle, so this rule uses preset cadences with configurable dates. Select the cadence and dates that best fit your payroll and operating schedule. Cadence Settlement date Common use case Weekly Choose one day per week (Monday - Friday) for funds to settle Weekly operations Twice monthly Preset to 11th and 25th settlement Bi-monthly payroll Monthly Choose one date per month Monthly payroll When applicable, Rho checks your Checking balance at 8 a.m. ET on business days. If your balance falls below your minimum, Rho initiates a Treasury liquidation so the funds settle on your next scheduled date. Why these cadences? Treasury → Checking transfers can take up to 3 business days to settle. These cadences are designed to help ensure funds are available in Checking when you need them, while keeping more of your excess cash working in Treasury. For additional flexibility between settlement dates, we recommend keeping about 3 months of operating cash in Checking. On balance change Choose balance monitoring if you'd rather not wait for a scheduled date. See the section below. Using balance monitoring Balance monitoring shortens the wait between transfers. Instead of checking once a day and settling funds on a date you pick, Rho checks your balance after every transaction and initiates a transfer once your threshold is crossed. Balance monitoring is available for all maintain balance rules — minimum, maximum, and $0 — across Treasury → Checking and Checking ↔ Checking. What triggers a transfer Rule Trigger Minimum balance Your balance falls below your minimum Maximum balance Your balance rises above your maximum $0 balance Any funds arrive in the account How much moves Rho transfers only what's needed to bring your account back to your threshold, and accounts for any transfer already on its way. If a transfer is already in progress, Rho subtracts it before calculating the next one, so we’re never over-transferring while funds are settling. Timing Treasury → Checking – one transfer per business day. If your balance crosses the threshold again the same day, Rho waits until the next business day to initiate a transfer. Transfers triggered outside market hours, on weekends, or on market holidays initiate next business day. Funds take up to three business days to settle. Checking ↔ Checking – transfers start immediately each time your threshold is crossed, with no daily limit. Funds settle the same day. What balance monitoring does and doesn't change Balance monitoring changes when a transfer starts , not how long it takes to arrive. A Treasury → Checking transfer still takes up to three business days to settle. If your balance drops the day before payroll, balance monitoring starts the transfer immediately, but the funds may not arrive in time. For obligations you can't miss, keep your minimum high enough to cover them. Switching between modes You can switch an existing rule between Schedule and Balance change at any time. The change takes effect immediately, and any transfer already in progress completes as planned. Rule limits You can have up to 5 active auto-transfer rules per organization. Each source and destination account pair can have only one rule . Rules that would create a circular flow of funds are blocked. For example, you can't create both a Operating → Payroll minimum balance rule and a Payroll → Operating maximum balance rule between the same accounts. Common scenarios My Treasury account doesn't have enough funds The transfer won't be completed, and you'll receive a notification. The rule ran, but no transfer happened Your account already met the balance requirement when the rule was evaluated, so no transfer was needed. My execution date falls on a weekend or market holiday The transfer runs on the prior business day. My balance dropped twice in one day For Treasury → Checking rules using balance monitoring, Rho transfers once per business day. The second drop is recorded and evaluated again the next business day. Checking ↔ Checking rules have no daily limit. My balance dropped after hours or over the weekend Rho evaluates your balance right away and initiates the Treasury withdrawal on the next business day, when markets reopen. Checking ↔ Checking transfers aren't affected and run as usual. A transfer failed or was rejected Rho removes it from the pending total and re-evaluates your balance right away, so a replacement transfer can start. Existing rule migration If your Treasury rule was on a weekly Thursday schedule, it has been moved to balance monitoring. Rho now checks your Checking balance after every transaction and initiates a transfer when it falls below your minimum, rather than waiting for Thursday. Before: If your Checking balance falls below $250,000, Rho initiates a Treasury sale in advance so funds settle in your Checking account every Thursday. Now: Whenever your Checking balance falls below $250,000, Rho initiates a Treasury sale for the amount needed to restore your minimum – up to once per business day. Your minimum balance and account settings remain the same. You can review your rule at any time from the Auto-transfer rules page, or switch back to a fixed schedule if you'd prefer funds to arrive on set dates. Frequently asked questions Is balance monitoring available for all rule types? Yes. Balance monitoring works with minimum, maximum, and $0 balance rules, for both Treasury → Checking and Checking ↔ Checking. Will balance monitoring get my funds there faster? It starts the transfer sooner, but settlement time is unchanged. Treasury → Checking still takes up to three business days; Checking ↔ Checking settles same-day. Are the preset Treasury schedules only for customers who were migrated from sweep rules? No. The preset schedules apply to all Treasury → Checking maintain minimum balance rules using Schedule mode. Custom schedules are available for Checking ↔ Checking transfers. Why is weekly the most frequent scheduled option for Treasury → Checking rules? Treasury → Checking transfers can take up to three business days to settle. These cadences help ensure funds are available when you need them, while keeping more of your excess cash working in Treasury. If you want funds to move more often than weekly, use balance monitoring instead. Can I create rules in both directions between the same two accounts? Can I use the same source account for two rules? No. Each account pair supports only one rule in one direction, and each account can only be the source of one rule. For example, if you have an Operating → Payroll rule and a Treasury → Operating rule: You can't also create a Payroll → Operating rule for that same account pair You can't create another rule with Treasury as the source (such as Treasury → Payroll), since Treasury is already a source elsewhere Can one Treasury account fund multiple Checking accounts? No, only one Checking account can be funded by Treasury. What happened to the top-up amount from the previous sweep feature? Auto-transfer rules now transfer only the amount needed to restore your account to its minimum balance. To maintain additional cash in your Checking account, set a higher minimum balance threshold or recurring transfer amount. Need help?

For quick answers, reference our Understanding Rho Treasury article. Rho Treasury is the trade name of RBB Treasury LLC, an SEC-registered investment adviser and a subsidiary of Rho. RBB Treasury LLC gives investment advice and manages your portfolio. Apex Clearing Corp. and Interactive Brokers LLC hold your assets, run your trades, and produce your statements. Understanding the Rho Treasury dashboard Navigate to the Treasury tab in Rho. Rho Treasury has two overview tiles at the top of the dashboard, and the rest is organized into two tabs, Activity and Portfolio. Overview Balance is the total market value of your portfolio as of the last market close, including cash, invested assets, and yield earned, net of fees. Pending transfers are not included. Available same day is the amount you can transfer from Treasury to your Rho Checking account that day. It includes your IJTXX balance and any uninvested cash. Submit the transfer by 3:00 PM ET on a business day to use funds the same day. Realized P&L includes interest earned on T-Bills at maturity or sale, fund dividends paid, and proceeds from completed asset sales. The portfolio section shows you the target allocation of your Treasury portfolio across the four asset classes. If you still hold VFSTX, it appears as a separate position alongside VFSUX. Together they make up your Vanguard allocation. Net yield is the weighted average yield across your portfolio: Σ (target allocation % × current asset yield) - management fees This is net of Rho's management fee and updates automatically as underlying yields change. Activity A chronological log of all activity including deposits, withdrawals, asset purchases, sales, and maturities, fund dividends, cash interest, management fee charges, market value adjustments, and ACATs. Market value adjustments are daily revaluations of your Treasury holdings to reflect current NAV. These are unrealized. No money moves until you sell. Portfolio Treasury Bills (T-Bills) T-Bills are short-term U.S. government debt securities backed by the U.S. Treasury. They are a stable, predictable way to earn yield on idle funds, with maximum principal stability and no NAV variability. Rho exclusively purchases 13-week (90-day) T-Bills in $1,000 increments. If your proportional T-Bill allocation falls below $1,000 for a given deposit, that portion is held as cash and invested at next deposit or rebalance or swept into IJTXX (if enrolled). You can evaluate your holdings details by reviewing the following information in the Portfolio tab. Field What it means Yield Based on the difference between purchase price and face value, and the holding period Shares Quantity of T-Bills held Market value Market value = shares x current price Purchase price Average discounted price paid per bill Current price Yesterday's market price per share Current allocation Shows your actual allocation and drift from your target Maturity date The date the T-Bill term ends and face value is paid T-Bills are purchased at a discount and redeemed at face value at maturity. For example, a T-Bill purchased for $989.96 matures at $1,000.00, the $10.04 difference is your return. At maturity, T-Bill face value is credited as cash and automatically reinvested per your target allocation. If sold before maturity, the T-Bill is sold at current market price which may result in receiving less than your purchase price. Note: T-Bill interest is subject to federal income tax but exempt from state and local income taxes. Mutual Funds Morgan Stanley Ultra-Short Income Fund (MULSX) MULSX invests in high-quality, short-duration money market instruments including commercial paper, corporate debt, and asset-backed securities. NAV is variable but designed to remain highly stable. Vanguard Short-Term Investment-Grade Fund (VFSTX & VFSUX) VFSUX and VFSTX are currently closed to new investments in Rho Treasury. Learn more about why here . VFSUX and VFSTX are share classes of the same Vanguard fund. It invests mainly in investment-grade corporate bonds, with additional exposure to government and securitized debt. NAV moves with changes in interest rates. VFSUX is the Admiral Shares class and has a lower expense ratio. It is the only Vanguard fund available for new allocations. If you hold VFSTX today: your position stays invested and all new money buys VFSUX. You still set a single Vanguard target in the 'Edit Portfolio' flow, but your 'Portfolio' tab will show separate VFSTX and VFSUX positions that together make up that target. When your Vanguard allocation is sold from, shares are sold first-in, first-out, so VFSTX is sold before VFSUX. Once your VFSTX balance reaches $0.00, only VFSUX appears. VFSTX entries remain in your Activity history. Dividends accrue daily and are paid monthly at the start of each calendar month. Dividends appear as realized P&L in your Treasury overview and are reinvested per your target allocation. You can evaluate your holdings by reviewing the following information in the Portfolio tab.

The fund seeks to maintain a stable share price of $1.00. IJTXX works as a cash sweep. Cash allocated to IJTXX remains in your account during the day, Apex Clearing Corp. ("Apex"), an unaffiliated third-party custodian, automatically sweeps the cash into the fund each business day. There are no minimum purchase or redemption amounts. Dividends accrue daily and are paid monthly. IJTXX is the only Rho Treasury investment with same-day access. Submit a withdrawal by 3:00 PM ET on a business day, and funds will land in your Rho Checking account that same day, provided the amount does not exceed your available balance. You must accept the sweep terms before IJTXX becomes active on your account. For more details, see our helpful article . You can evaluate your holdings details by reviewing the following information in the Portfolio tab. Field What it means Yield JPMorgan (IJTXX): 7-Day SEC Yield Shares Quantity of fund shares held Market value Market value = shares x current price Purchase price Average NAV at time of purchase Current price Yesterday's NAV per share Current allocation Shows your actual allocation and drift from your target Distribution date Dividend distribution date Cash Cash in your Treasury portfolio is money waiting to be invested. It comes from deposits, sale and maturity proceeds, dividends, and T-Bill purchase rounding differences. If you are enrolled in the IJTXX sweep, Apex moves idle cash into IJTXX at the end of each business day, so cash rarely sits uninvested overnight. If you are not enrolled, cash earns a small amount of interest and is reinvested across your target assets on the 6th of every month. Cash interest is paid monthly, mid-month.

Click the ‘Documents’ button in the upper-right corner of the Rho Treasury page to open the statements page. Funding your portfolio New funds top up IJTXX first, then go to your other assets. If your IJTXX balance is below its target percentage, incoming funds are allocated to IJTXX until the target is restored. Any remaining money is invested proportionally across T-Bills, MULSX, and VFSTX or VFSUX at your target percentages. If IJTXX is already at target, the full amount is invested proportionally across all four assets. This applies to deposits you make, T-Bill maturity proceeds, fund dividends, and cash interest. IJTXX is refilled first because it is the asset you draw from first. Investments take 1 to 2 business days to settle. IJTXX settles on the same business day. Portfolio allocation You control how your cash is split across assets. Allocations are percentage-based, set in 5% increments, and must total 100%. Four preset strategies are available as starting points, or you can build a custom allocation: Strategy Holding period Allocation Best for Maximum liquidity Same day 100% IJTXX Cash you may need at any time. Capital preservation 3-6 months 50% IJTXX 50% T-Bills Cash you may need within 3 months. Maximum principal stability, low NAV variability. Balanced income 6-12 months 25% IJTXX 50% T-Bills 25% MULSX Cash you won't need for at least 4 months. Adds modest yield while keeping a liquidity buffer. Custom Your choice! Note: The Vanguard fund is closed to new investments . If your account already holds Vanguard (VFSTX or VFSUX), any change you make to your portfolio caps Vanguard at 35%. If you hold more than 35% today, a change sells the extra shares at the current market price, and this sale can realize a loss. This limit reflects the fund's longer time horizon. It is best suited for cash you won't need for at least 12 months, not operating capital. Contact the Rho team if you need a higher limit or have questions. Editing your portfolio Navigate to Treasury → Edit Portfolio Review your current allocation and compare asset options Adjust allocation percentages in 5% increments (must total 100%) Review your updated blended net yield Review & confirm Rho rebalances by selling from over-allocated assets and buying into under-allocated ones. Typically takes 2 to 4 business days to complete. You cannot make changes while a rebalance is in progress. Your funds remain invested during this time. How rebalancing works Your portfolio stays on target through: New money in – every deposit, maturity, dividend, and interest payment is automatically invested according to your target allocation, with IJTXX topped up first. Allocation changes – editing your target triggers an immediate rebalance. Monthly rebalancing – on the 6th of each month, Rho reviews your portfolio. If any holding has drifted more than 5% from its target allocation, we automatically rebalance your portfolio. Withdrawing from your portfolio How your withdrawal is funded depends on the amount you request and your same-day available balance. If your withdrawal is equal to or less than your available balance , the full amount is pulled from IJTXX and cash. Request it before 3:00 PM ET on a business day and Rho wires the funds to your Rho Checking account the same day. Request it after 3:00 PM ET and the funds arrive the next business day. If your withdrawal is more than your available balance , the full amount comes from your other assets instead. Rho sells T-Bills, MULSX, and your Vanguard position proportionally to your current allocation. Your IJTXX balance is left untouched, so your same-day buffer stays intact. These sales settle on the normal timelines below. We do not split a withdrawal across IJTXX and your other assets, and you cannot select which assets are sold. Shares are sold first-in, first-out (FIFO). Example: Your portfolio is 20% IJTXX ($20,000) and 80% MULSX ($80,000). You withdraw $15,000 before 3:00 PM ET. It comes from IJTXX and lands in Checking the same day. You withdraw $30,000. That is more than your $20,000 IJTXX balance, so the full $30,000 is sold from MULSX. Your IJTXX balance stays at $20,000, and the funds arrive in 1 to 2 business days. Settlement timelines Asset Cutoff Allocation IJTXX 3:00 PM ET Same business day T-Bills 5:00 PM ET Next business day MULSX 4:00 PM ET 1 to 2 business days VFSUX / VFSTX 4:00 PM ET 1 to 2 business days Cutoffs apply on business days only. Requests made on weekends and market holidays are processed on the next business day. After a withdrawal, incoming deposits, dividends, and maturity proceeds refill IJTXX first, so your same-day buffer is restored over time.
