2. Module 1: FINRA SIE, Series 7 Top-Off & NASAA Series 63/65/66

2.1 Equity Options Strategies: Breakeven, Maximum Gain & Maximum Loss

Every listed equity option contract represents $100\text{ shares}$ of the underlying stock and settles on $\text{T}+1$ (exercise settlement is also $\text{T}+1$).

Strategy & Construction	Breakeven Formula(s)	Maximum Gain Formula	Maximum Loss Formula
Long Call (Buy 1 Call at strike $K$, premium $P$)	$K + P$	Unlimited (as $S_T \to \infty$)	$P$ (premium paid)
Short (Naked) Call (Write 1 Call at strike $K$, premium $P$)	$K + P$	$P$ (premium received)	Unlimited (as $S_T \to \infty$)
Long Put (Buy 1 Put at strike $K$, premium $P$)	$K - P$	$K - P$ (if stock falls to $$0$)	$P$ (premium paid)
Short (Naked) Put (Write 1 Put at strike $K$, premium $P$)	$K - P$	$P$ (premium received)	$K - P$ (if stock falls to $$0$)
Covered Call (Long 100 sh at $S_0$ + Short 1 Call at $K, P$)	$S_0 - P$	$(K - S_0) + P$ (capped at $K$)	$S_0 - P$ (if stock falls to $$0$)
Protective Put (Long 100 sh at $S_0$ + Long 1 Put at $K, P$)	$S_0 + P$	Unlimited ($S_T - S_0 - P$)	$(S_0 - K) + P$ (floor at $K$)
Short Stock + Long Call (Short 100 sh at $S_0$ + Long 1 Call at $K, P$)	$S_0 - P$	$S_0 - P$ (if stock falls to $$0$)	$(K - S_0) + P$ (capped at $K$)
Long Straddle (Long 1 Call + Long 1 Put, same $K$, total debit $TP$)	$K + TP$ and $K - TP$ (dual)	Unlimited on upside; $K - TP$ downside	$TP = P_{\text{call}} + P_{\text{put}}$ (at $S_T = K$)
Short Straddle (Short 1 Call + Short 1 Put, same $K$, total credit $TP$)	$K + TP$ and $K - TP$ (dual)	$TP = P_{\text{call}} + P_{\text{put}}$ (at $S_T = K$)	Unlimited on upside
Vertical Call Spread (Buy $K_L$, Sell $K_H$ or vice versa; net premium $NP$)	$K_L + NP$ ("CAL: Add to Low")	Debit: $(K_H - K_L) - ND$; Credit: $NC$	Debit: $ND$; Credit: $(K_H - K_L) - NC$
Vertical Put Spread (Buy $K_H$, Sell $K_L$ or vice versa; net premium $NP$)	$K_H - NP$ ("PUH: Subtract from High")	Debit: $(K_H - K_L) - ND$; Credit: $NC$	Debit: $ND$; Credit: $(K_H - K_L) - NC$

2.2 Municipal Bonds, Tax-Equivalent Yield & MSRB Rules

1. General Obligation (GO) Bonds vs. Revenue Bonds:
   • GO Bonds: Backed by the taxing power of the issuing state or municipality. Local GOs are backed by ad valorem real property taxes ($\text{Tax} = \text{Assessed Value} \times \text{Millage Rate}$, where $1\text{ mill} = $0.001 = $1\text{ per }$1,000$); state GOs are backed by income and sales taxes. Subject to statutory/constitutional debt limits and voter referendums.
   • Revenue Bonds: Self-supporting bonds backed by user fees, tolls, lease rentals, or special excise taxes under a Trust Indenture. Not subject to statutory debt limits or voter approval. Analyzed via the Debt Service Coverage Ratio: $$\text{DSCR} = \frac{\text{Gross Revenue} - \text{Operating & Maintenance Expenses}}{\text{Annual Principal} + \text{Interest Debt Service}} = \frac{\text{Net Revenue}}{\text{Total Debt Service}}$$
2. Tax-Equivalent Yield (TEY): $$\text{Tax-Equivalent Yield (TEY)} = \frac{\text{Tax-Exempt Municipal Yield}}{1 - \text{Federal Marginal Tax Rate}}, \qquad \text{Tax-Free Equivalent Yield} = \text{Taxable Yield} \times (1 - \text{Marginal Tax Rate})$$
3. IRS Amortization vs. Accretion Rules:
   • Premium Municipal Bond: Must be amortized downward toward par over the remaining life of the bond. Cost basis drops each year so that holding to maturity produces $0 capital loss (preventing a tax-deductible loss on a tax-exempt bond).
   • Original Issue Discount (OID) Municipal Bond: Accretes upward to par as tax-exempt interest income; holding to maturity results in $0 capital gain.
   • Secondary-Market Discount Municipal Bond: Accretion to par at maturity represents realized market appreciation and is taxed as ordinary income at maturity!
4. MSRB Conduct Rules:
   • Rule G-20 (Gifts): Maximum $100 per person per year (excludes normal business entertainment where the host is present and promotional items of nominal value).
   • Rule G-37 (Political Contributions / Pay-to-Play): Prohibits a broker-dealer from engaging in negotiated municipal underwriting business with an issuer for 2 years following a campaign contribution by a Municipal Finance Professional (MFP) to an official of that issuer, unless the MFP is entitled to vote for that official and contributes $\le $250$ per election.

2.3 Regulation T & FINRA Rule 4210 Margin Mechanics

• Initial Margin (Federal Reserve Regulation T): 50% of the transaction price for both long purchases and short sales (FINRA minimum initial equity is $2,000—or 100% of the purchase price if buying less than $2,000 in a long account; a short account always requires at least $2,000 initial equity).
• Minimum Maintenance Margin (FINRA Rule 4210):
  • Long Margin Account: Equity must be at least 25% of Long Market Value ($\text{LMV}$), where $\text{LMV} - \text{Debit Balance (DB)} = \text{Equity}$. $$\text{Long Maintenance Margin Call Trigger LMV} = \frac{\text{Debit Balance}}{1 - 0.25} = \frac{\text{Debit Balance}}{0.75}$$
  • Short Margin Account: Equity must be at least 30% of Short Market Value ($\text{SMV}$), where $\text{Credit Balance (CB)} - \text{SMV} = \text{Equity}$. $$\text{Short Maintenance Margin Call Trigger SMV} = \frac{\text{Credit Balance}}{1 + 0.30} = \frac{\text{Credit Balance}}{1.30}$$
• Special Memorandum Account (SMA): When a long margin account has $\text{Equity} > 50% \times \text{LMV}$, the Excess Equity ($\text{Equity} - 0.50 \times \text{LMV}$) is credited to SMA. Each $$1$ of SMA provides $$1$ of cash withdrawal power (provided withdrawal does not push equity below the 25% maintenance floor) or $$2$ of Reg T buying power.

2.4 Securities Regulation, SEC Reg BI, Rule 144 & T+1 Settlement

• SEC Regulation Best Interest (Reg BI — Rule 15l-1): Requires broker-dealers and associated persons making a recommendation of any securities transaction or investment strategy (including account-type and rollover recommendations) to a retail customer to act in the customer's best interest without placing the broker-dealer's financial interest ahead of the customer's, satisfied via four obligations: 1) Disclosure Obligation (including Form CRS), 2) Care Obligation, 3) Conflict of Interest Obligation, and 4) Compliance Obligation.
• SEC Rule 144 (Restricted & Control Securities):
  • Restricted Stock (unregistered private placements): 6-month mandatory holding period for SEC reporting issuers (12 months for non-reporting issuers).
  • Affiliates (Control Persons: Officers, Directors, $>10%$ Shareholders): Must file Form 144 when placing the sell order (if selling $>5,000\text{ shares}$ or $>$50,000$ within any 90-day period) and are capped every 90 days at the GREATER of:
    1. 1% of the total outstanding shares of the same class, OR
    2. The average weekly reported trading volume over the preceding 4 calendar weeks.
• SEC Rule 15c6-1 (T+1 Standard Settlement & Ex-Dividend Date): Regular-way settlement for equities, corporate bonds, municipal bonds, UITs, Treasury securities, and options is $\text{T}+1$ (1 business day after trade date). Consequently, the Ex-Dividend Date is the Record Date itself (an investor must purchase the stock at least 1 business day before the Record Date so that settlement occurs on or before the Record Date). Cash settlement is $\text{T}+0$ (same day), and cash trades trade ex-dividend 1 business day after the Record Date.

3.2 CFA Institute Standards of Professional Conduct (Standards I–VII) & GIPS

1. Standard I(A) Knowledge of the Law: Always follow the strictest applicable law, rule, or regulation. If a colleague or employer engages in illegal or unethical activity, first attempt to stop it through a supervisor or compliance officer and dissociate from the activity (removing your name from reports, stepping off the engagement, or resigning in extreme cases).
2. Standard II(A) Material Nonpublic Information (MNPI) & Mosaic Theory: Combining public material information with nonmaterial nonpublic information (e.g., store channel checks, supplier interviews) is permitted under the Mosaic Theory.
3. Standard III(A) Loyalty, Prudence, and Care (Soft Dollars): Client brokerage commissions belong to the client and may be used exclusively to purchase research and brokerage services that directly assist the manager in the investment decision-making process.
4. Standard VI(B) Priority of Transactions: Client and employer trades must execute ahead of any account in which the Member or Candidate is a beneficial owner (or has a pecuniary interest). Fee-paying family accounts where the Member has no beneficial ownership must be treated on the same footing as all other regular client accounts.
5. Global Investment Performance Standards (GIPS):
   • Compliance may be claimed only on a firm-wide basis.
   • All actual, fee-paying, discretionary portfolios (including terminated portfolios up through their last full measurement period) MUST be included in at least one composite defined by strategy/mandate. Non-discretionary portfolios MUST NEVER be included in composites.

3.3 Quantitative Methods, Macroeconomics & Covered Interest Rate Parity

• Money-Weighted Return (MWRR) vs. Time-Weighted Return (TWRR): $$\text{TWRR} = \left[(1 + \text{HPR}_1)(1 + \text{HPR}_2)\cdots(1 + \text{HPR}_T)\right]^{1/T} - 1$$ Because TWRR eliminates the distorting effect of external client cash inflows and outflows, GIPS mandates time-weighted returns for most liquid investment composites.
• Roy's Safety-First Criterion: Minimizes $P(R_p < R_L)$ by maximizing: $$\text{SFRatio} = \frac{E(R_p) - R_L}{\sigma_p}$$
• Bayes' Formula: $$P(\text{Event} \mid \text{Information}) = \frac{P(\text{Information} \mid \text{Event}) \times P(\text{Event})}{\sum_i P(\text{Information} \mid \text{Event}_i) P(\text{Event}_i)}$$
• Covered Interest Rate Parity (CIRP — Price/Base Currency Quote): $$F_{P/B} = S_{P/B} \times \left[\frac{1 + r_P \left(\frac{\text{Actual}}{360}\right)}{1 + r_B \left(\frac{\text{Actual}}{360}\right)}\right] \implies \frac{F_{P/B} - S_{P/B}}{S_{P/B}} \approx (r_P - r_B)\left(\frac{\text{Actual}}{360}\right)$$ The currency with the higher nominal interest rate always trades at a forward discount.

3.4 Financial Statement Analysis (IFRS vs. US GAAP) & Corporate Issuers

Accounting Topic	US GAAP Treatment	IFRS Treatment	Analytical Formula / Adjustment
Cash Flow Classification	Interest Paid, Interest Received, Dividends Received = CFO; Dividends Paid = CFF	Interest/Dividends Paid = CFO or CFF; Interest/Dividends Received = CFO or CFI	$\text{FCFF} = \text{CFO} + \text{Int}(1-t) - \text{FCInv}$; $\text{FCFE} = \text{CFO} - \text{FCInv} + \text{Net Borrowing}$
Inventory Valuation	FIFO, LIFO, or Weighted Average; Lower of Cost or Market (LIFO/Retail) / Lower of Cost or NRV (FIFO)	FIFO or Weighted Average ONLY (LIFO is prohibited); Lower of Cost or Net Realizable Value (NRV)	$\text{Inv}{\text{FIFO}} = \text{Inv}{\text{LIFO}} + \text{LIFO Reserve}$; $\text{COGS}{\text{FIFO}} = \text{COGS}{\text{LIFO}} - \Delta\text{LIFO Reserve}$
Impairment of PP&E & Intangibles	Two-step test: 1) Carrying Value $>$ Undiscounted Future Cash Flows (recoverability); 2) Write down to Fair Value. Reversal is PROHIBITED for assets held for use	Single-step test (IAS 36): Write down if Carrying Value $>$ Recoverable Amount $=\max(\text{Fair Value less Costs to Sell}, \text{Value in Use})$. Reversal is PERMITTED (except Goodwill)	Reversal under IAS 36 is capped at the depreciated carrying value that would have existed had no impairment occurred
R&D Expenditures	Both Research and Development costs are expensed as incurred (with narrow software exception after technological feasibility)	Research costs are expensed; Development costs are capitalized once commercial/technical feasibility criteria are met	Capitalizing vs. expensing increases Year 1 Net Income, Assets, Equity, and CFO, while decreasing CFI

• 5-Way Extended DuPont Decomposition: $$\text{ROE} = \underbrace{\left(\frac{\text{NI}}{\text{EBT}}\right)}{\text{Tax Burden}} \times \underbrace{\left(\frac{\text{EBT}}{\text{EBIT}}\right)}{\text{Interest Burden}} \times \underbrace{\left(\frac{\text{EBIT}}{\text{Revenue}}\right)}{\text{EBIT Margin}} \times \underbrace{\left(\frac{\text{Revenue}}{\text{Avg Assets}}\right)}{\text{Asset Turnover}} \times \underbrace{\left(\frac{\text{Avg Assets}}{\text{Avg Equity}}\right)}_{\text{Financial Leverage}}$$
• Modigliani-Miller Propositions I & II (With Corporate Taxes $t > 0$, No Distress Costs): $$V_L = V_U + t \cdot D, \qquad r_e = r_0 + (r_0 - r_d)(1 - t)\left(\frac{D}{E}\right), \qquad \text{WACC} = w_e r_e + w_d r_d(1 - t)$$

---

4. Module 3: CFA Level I — Session 2 (Equity, Fixed Income, Derivatives, Alternatives & Portfolio Management)

4.1 Equity Valuation & Enterprise Value

• Gordon Growth Model (GGM) & Justified Leading/Trailing P/E: $$V_0 = \frac{D_0(1 + g)}{r - g} = \frac{D_1}{r - g}, \qquad g = b \times \text{ROE} = (1 - \text{Payout Ratio}) \times \text{ROE}, \qquad \frac{P_0}{E_1} = \frac{1 - b}{r - g}, \qquad \frac{P_0}{E_0} = \frac{(1 - b)(1 + g)}{r - g}$$
• Present Value of Growth Opportunities (PVGO): $$P_0 = \frac{E_1}{r} + \text{PVGO}$$
• Enterprise Value (EV): $$\text{EV} = \text{MV of Common Equity} + \text{MV of Preferred Stock} + \text{MV of Total Debt} + \text{Noncontrolling Interest} - \text{Cash & Short-Term Investments}$$

4.2 Fixed Income: Spot/Forward Rates, Spreads, Duration & Convexity

1. Implied Forward Rate Bootstrapping: $$(1 + z_{t+k})^{t+k} = (1 + z_t)^t (1 + {}{t}f{k})^k \implies {}{1}f{1} = \frac{(1 + z_2)^2}{1 + z_1} - 1$$
2. Z-Spread vs. Option-Adjusted Spread (OAS):
   • Callable Bond: $\text{OAS} = \text{Z-Spread} - \text{Call Option Cost in bps} \implies \text{OAS} < \text{Z-Spread}$.
   • Putable Bond: $\text{OAS} = \text{Z-Spread} + \text{Put Option Benefit in bps} \implies \text{OAS} > \text{Z-Spread}$.
3. Duration, Effective Duration & Convexity Price Approximation: $$\text{ModDur} = \frac{\text{MacDur}}{1 + \text{YTM}/m}, \qquad \text{ApproxModDur / EffDur} = \frac{PV_- - PV_+}{2 \times (\Delta\text{Yield or }\Delta\text{Curve}) \times PV_0}, \qquad \text{ApproxConv} = \frac{PV_- + PV_+ - 2 PV_0}{(\Delta\text{Yield})^2 \times PV_0}$$ $$\frac{\Delta P_{\text{Full}}}{P_{\text{Full}}} \approx -\text{AnnModDur} \times (\Delta\text{Yield}) + \frac{1}{2} \times \text{AnnConvexity} \times (\Delta\text{Yield})^2$$

4.3 Derivatives: Forward Pricing, Put-Call Parity & Binomial Option Valuation

• Cost-of-Carry Forward Pricing & Intermediate Valuation: $$F_0(T) = \left[S_0 - PV_0(I) + PV_0(C)\right](1 + r)^T, \qquad V_t(T) = S_t - PV_t(I) + PV_t(C) - \frac{F_0(T)}{(1 + r)^{T - t}}$$
• European Put-Call Parity & Put-Call-Forward Parity: $$\underbrace{c_0 + \frac{X}{(1 + r)^T}}{\text{Fiduciary Call}} = \underbrace{p_0 + S_0}{\text{Protective Put}} = p_0 + \frac{F_0(T)}{(1 + r)^T}$$
• One-Period Binomial Model (Risk-Neutral Probability $\pi$): $$\pi = \frac{1 + r - d}{u - d}, \qquad V_0 = \frac{\pi V_1^+ + (1 - \pi) V_1^-}{1 + r}$$

4.4 Portfolio Management: CAPM (CML vs. SML) & Risk-Adjusted Performance Ratios

Metric / Line	Mathematical Formula	Risk Denominator	Portfolio / Security Applicability
Capital Market Line (CML)	$E(R_p) = R_f + \left(\frac{E(R_M) - R_f}{\sigma_M}\right)\sigma_p$	Total Risk ($\sigma_p$)	Efficient portfolios ONLY (combinations of $R_f$ and Market Portfolio $M$)
Security Market Line (SML / CAPM)	$E(R_i) = R_f + \beta_i [E(R_M) - R_f]$, where $\beta_i = \rho_{i,M}\frac{\sigma_i}{\sigma_M}$	Systematic Risk ($\beta_i$)	All individual securities and portfolios (plots above SML $\implies \alpha_i > 0 \implies$ Undervalued)
Sharpe Ratio & $M^2$	$\text{Sharpe}_p = \frac{R_p - R_f}{\sigma_p}, \quad M^2 = R_f + \text{Sharpe}_p \cdot \sigma_M$	Total Risk ($\sigma_p$)	Evaluates standalone total portfolios where unsystematic risk is present
Treynor Ratio & Jensen's $\alpha$	$\text{Treynor}_p = \frac{R_p - R_f}{\beta_p}, \quad \alpha_p = R_p - [R_f + \beta_p(R_M - R_f)]$	Systematic Risk ($\beta_p$)	Evaluates well-diversified sub-portfolios inside a broader multi-manager structure
Information Ratio (IR)	$\text{IR} = \frac{R_p - R_B}{\sigma_{R_p - R_B}} = \frac{\text{Active Return}}{\text{Tracking Error}}$	Active Risk ($\sigma_{p-B}$)	Evaluates an active manager's consistency relative to their specific style benchmark $B$

5. Module 4: AICPA CPA Evolution (Core AUD, FAR, REG + BAR, ISC, TCP)

5.1 Financial Accounting & Reporting (FAR & BAR)

1. ASC 606 Revenue from Contracts with Customers:
   • Allocate total transaction price across distinct performance obligations using relative standalone selling prices ($\text{SSP}$).
   • In over-time construction contracts (cost-to-cost input method: $% \text{ Complete} = \frac{\text{Costs Incurred to Date}}{\text{Total Estimated Costs}}$), any expected overall contract loss ($\text{Total Estimated Costs} > \text{Total Contract Price}$) must be recognized 100% immediately in the current period.
2. ASC 842 Leases (Lessee Dual Classification Model — "OWNES"):
   • All leases $> 12\text{ months}$ record a Right-of-Use (ROU) Asset and Lease Liability on the balance sheet at the present value of lease payments.
   • Meeting any of the 5 OWNES criteria (Ownership transfers, Written purchase option reasonably certain to be exercised, NPV $\ge 90%$ of FV, Economic life $\ge 75%$, Specialized asset) creates a Finance Lease (separate Interest Expense + ROU Amortization; principal in CFF, interest in CFO). Failing all 5 creates an Operating Lease (single straight-line Lease Expense; ROU Amortization is the plug $= \text{Lease Expense} - \text{Effective Interest}$; 100% CFO).
3. GASB State & Local Governmental Accounting (GRASPP vs. SE / CIPP):
   • Governmental Funds (GRASPP: General, Special Revenue, Debt Service, Capital Projects, Permanent): Current Financial Resources measurement focus + Modified Accrual basis (revenues recognized when measurable and available within 60 days; no fixed assets or long-term debt on the fund balance sheet; Fund Balance classified as Nonspendable, Restricted, Committed, Assigned, Unassigned—where positive Unassigned can exist only in the General Fund).
   • Proprietary Funds (SE: Internal Service, Enterprise) and Fiduciary Funds (CIPP: Custodial, Investment Trust, Private-Purpose Trust, Pension/OPEB Trust): Economic Resources measurement focus + Full Accrual basis.

5.2 Auditing & Attestation (AUD) and Information Systems & Controls (ISC)

6. Module 5: UK Solicitors Qualifying Examination — SRA SQE1 (FLK1 & FLK2) & SQE2

6.1 FLK1: Contract, Tort, Dispute Resolution (CPR), Business Law & Public Law

1. Contract Law:
   • Varying Existing Duties: Williams v Roffey Bros (factual practical benefit is valid consideration for a promise to pay MORE absent economic duress) vs. Foakes v Beer and Re Selectmove (practical benefit is NOT valid consideration for a promise to accept LESS in full satisfaction of an existing debt; requires a Deed, Pinnel's Case accord and satisfaction, or Promissory Estoppel as a shield under Central London Property Trust v High Trees House).
   • Exemption Clauses: Both UCTA 1977 s.2(1) (B2B) and CRA 2015 s.65 (B2C) render any clause excluding or restricting liability for death or personal injury resulting from negligence automatically VOID.
2. Tort Law:
   • Psychiatric Harm (Alcock & Paul [2024] UKSC 1): A Primary Victim (within the zone of physical danger, Page v Smith) needs only foreseeability of physical harm. A Secondary Victim (not in physical danger) must prove a recognised psychiatric illness induced by sudden shock plus: 1) close tie of love and affection (presumed only for parent/child and spouse/fiancé), 2) proximity in time and space to an external accident or its immediate aftermath (Paul v Royal Wolverhampton NHS Trust), and 3) direct unaided perception.
   • Occupiers' Liability: OLA 1957 (visitors: covers personal injury AND property damage) vs. OLA 1984 (trespassers: covers personal injury ONLY, s.1(8), subject to the s.1(3) three-stage test).
3. Dispute Resolution (Civil Procedure Rules — CPR):
   • Deemed Service: A Claim Form (CPR 6.14) is ALWAYS deemed served on the second business day after completing the relevant step in CPR 7.5(1), regardless of method. Other Documents (CPR 6.26) are deemed served on the same business day if sent by instant method (email/personal delivery) before 4:30 PM on a business day (otherwise next business day), or the second day after posting by first-class post if a business day.
   • 4 Allocation Tracks (CPR 26): Small Claims ($\le \pounds 10,000$), Fast Track ($\pounds 10,000\text{–}\pounds 25,000$, trial $\le 1\text{ day}$), Intermediate Track ($\pounds 25,000\text{–}\pounds 100,000$, trial $\le 3\text{ days}$, $\le 2\text{ oral experts/party}$, Fixed Recoverable Costs), and Multi-Track ($> \pounds 100,000$).
   • Setting Aside Default Judgment & Denton Test: Check CPR 13.2 (mandatory if irregularly entered) first, then CPR 13.3 (discretionary: real prospect of successfully defending OR other good reason + promptness) + the 3-stage Denton v TH White (CPR 3.9) test (1. Seriousness and significance of breach, 2. Why default occurred, 3. All the circumstances of the case).
4. Business Law & Insolvency (CA 2006 & IA 1986):
   • Shareholder Ordinary Resolution ($> 50%$) controls on directors: s.188 (guaranteed service contract $> 2\text{ years}$), s.190 (Substantial Property Transaction $> \pounds 100,000$, or $> 10%$ net assets AND $> \pounds 5,000$), s.197 (loans $> \pounds 10,000$). Written Resolutions (s.288) cannot be used to remove a director (s.168) or auditor (s.510) before expiry of term.
   • Insolvency Clawbacks: s.238 Undervalue (2 years), s.239 Preference (6 months unconnected / 2 years connected; requires subjective desire to prefer, negated by commercial pressure per Re MC Bacon), s.245 Floating Charge (12 months unconnected / 2 years connected). Prescribed Part is capped at $\pounds 800,000$.

8. 20 Fully Worked Exam-Style Practice Problems

Problem 1 — FINRA Series 7: Equity Options (Bull Call Spread vs. Long Straddle)

Question: An investor buys 1 XYZ Oct 50 Call at $$4.80$ and simultaneously writes 1 XYZ Oct 60 Call at $$1.30$ when XYZ stock is at $$51.00$. Calculate the investor's net debit, breakeven stock price, maximum potential gain, and maximum potential loss.

Solution:

1. Identify Strategy: Buying a lower-strike call ($K_L = $50$) and selling a higher-strike call ($K_H = $60$) with the same expiration is a Bull (Debit) Call Spread.
2. Net Debit & Maximum Loss: $\text{Net Debit} = $4.80 - $1.30 = $3.50\text{ per share} \times 100 = \mathbf{$350}$, which is also the Maximum Loss (if XYZ closes $\le $50$ at expiration).
3. Breakeven ("CAL: Add to Low"): $\text{Breakeven} = K_L + \text{Net Debit} = $50.00 + $3.50 = \mathbf{$53.50\text{ per share}}$.
4. Maximum Gain: $\text{Max Gain} = (K_H - K_L) - \text{Net Debit} = ($60.00 - $50.00) - $3.50 = $6.50\text{ per share} \times 100 = \mathbf{$650}$ (achieved at any stock price $\ge $60.00$).

Problem 2 — FINRA Series 7: Municipal Bond Tax-Equivalent Yield & Margin Call Trigger

Question: An investor in the $35%$ federal marginal income tax bracket is comparing a $4.29%$ tax-exempt general obligation municipal bond with a $6.30%$ taxable corporate bond. (a) Which bond provides the higher after-tax return? (b) Separately, if the investor buys $$60,000$ of marginable stock using $50%$ Reg T initial margin, at what Long Market Value (LMV) will a FINRA $25%$ maintenance margin call be triggered?

Solution:

1. Tax-Equivalent Yield (TEY): $$\text{TEY} = \frac{\text{Tax-Exempt Yield}}{1 - \text{Marginal Tax Rate}} = \frac{4.29%}{1 - 0.35} = \frac{4.29%}{0.65} = \mathbf{6.60%}$$ Because the municipal bond's $6.60%$ TEY exceeds the corporate bond's $6.30%$ taxable yield (or equivalently, the corporate bond's after-tax yield is $6.30% \times 0.65 = 4.095% < 4.29%$), the municipal bond provides the higher after-tax return.
2. FINRA 25% Long Maintenance Margin Call Trigger:
   • Initial purchase $= $60,000$; Reg T $50%$ deposit $= $30,000$; Debit Balance (DB) $= $30,000$. $$\text{Margin Call Trigger LMV} = \frac{\text{Debit Balance}}{0.75} = \frac{$30,000}{0.75} = \mathbf{$40,000}$$

Problem 3 — CFA Level I (Session 1): GIPS Composite Construction & Standard VI(B)

Question: Apex Asset Management claims GIPS compliance. The firm manages four portfolios using its US Large-Cap Value mandate: Portfolio A ($$50\text{M}$ discretionary, fee-paying active institutional account), Portfolio B ($$15\text{M}$ discretionary, non-fee-paying charity endowment), Portfolio C ($$25\text{M}$ account where the client must approve every trade in advance), and Portfolio D (a discretionary fee-paying account that terminated on 15 November 2025). Which portfolios MUST be included vs. excluded from the US Large-Cap Value composite for 2025?

Solution:

1. Portfolio A: Actual, fee-paying, discretionary portfolio $\implies$ MUST be included.
2. Portfolio B: Non-fee-paying discretionary portfolio $\implies$ Optional (may be included in the composite if the firm's policy includes non-fee-paying discretionary accounts and discloses the percentage of composite assets represented by non-fee-paying portfolios, but is not required).
3. Portfolio C: Client pre-approval of trades makes the account non-discretionary $\implies$ MUST BE EXCLUDED (GIPS strictly prohibits including non-discretionary portfolios in any composite).
4. Portfolio D: Terminated actual, fee-paying, discretionary portfolio $\implies$ MUST retain its historical performance in the composite through its last full measurement period (31 October 2025) to prevent survivorship bias.

Problem 4 — CFA Level I (Session 1): Bayes' Formula & Conditional Probability

Question: Based on historical credit data, $10%$ of high-yield bond issuers default within 3 years ($P(D) = 0.10$, $P(ND) = 0.90$). A credit-scoring model flags a 'Distress Warning' for $85%$ of issuers that subsequently default ($P(W \mid D) = 0.85$), but also falsely flags a 'Distress Warning' for $15%$ of issuers that do NOT default ($P(W \mid ND) = 0.15$). If an issuer receives a 'Distress Warning' today, what is the posterior probability $P(D \mid W)$ that it will default?

Solution:

1. Total Probability of a Distress Warning $P(W)$: $$P(W) = P(W \mid D)P(D) + P(W \mid ND)P(ND) = (0.85)(0.10) + (0.15)(0.90) = 0.085 + 0.135 = 0.220$$
2. Bayes' Formula for Posterior Probability $P(D \mid W)$: $$P(D \mid W) = \frac{P(W \mid D)P(D)}{P(W)} = \frac{0.085}{0.220} = \mathbf{0.3864\text{ (or }38.64%\text{)}}$$

Problem 5 — CFA Level I (Session 1): FCFF, FCFE, LIFO-to-FIFO & Diluted EPS

Question: A US GAAP corporation reports Net Income of $$160\text{M}$, Depreciation of $$30\text{M}$, Interest Expense of $$20\text{M}$, a tax rate of $25%$, Capital Expenditures ($\text{FCInv}$) of $$70\text{M}$, Working Capital Investment ($\text{WCInv}$) of $$10\text{M}$, and Net Debt Repayment of $$15\text{M}$ ($\text{Net Borrowing} = -$15\text{M}$). Calculate CFO, FCFF, and FCFE.

Solution:

1. Operating Cash Flow (CFO): $$\text{CFO} = \text{NI} + \text{Depreciation} - \text{WCInv} = $160\text{M} + $30\text{M} - $10\text{M} = \mathbf{$180\text{M}}$$
2. Free Cash Flow to the Firm (FCFF): $$\text{FCFF} = \text{CFO} + \text{Int}(1 - t) - \text{FCInv} = $180\text{M} + $20\text{M}(1 - 0.25) - $70\text{M} = $180\text{M} + $15\text{M} - $70\text{M} = \mathbf{$125\text{M}}$$
3. Free Cash Flow to Equity (FCFE): $$\text{FCFE} = \text{CFO} - \text{FCInv} + \text{Net Borrowing} = $180\text{M} - $70\text{M} + (-$15\text{M}) = \mathbf{$95\text{M}}$$

Problem 6 — CFA Level I (Session 1): Modigliani-Miller Propositions I & II with Taxes

Question: An all-equity firm has an unlevered market value $V_U = $400\text{M}$ and an unlevered cost of capital $r_0 = 9.5%$. It issues $$150\text{M}$ of permanent debt at $r_d = 5.5%$ to repurchase $$150\text{M}$ of equity. If the corporate tax rate is $t = 20%$ and there are no financial distress costs, calculate the levered firm value ($V_L$), the market value of levered equity ($E$), the levered cost of equity ($r_e$), and the post-recapitalization WACC.

Solution:

1. MM Proposition I with Taxes: $$V_L = V_U + t \cdot D = $400\text{M} + 0.20($150\text{M}) = \mathbf{$430\text{M}}$$ Since Debt $D = $150\text{M}$, Levered Equity $E = V_L - D = $430\text{M} - $150\text{M} = \mathbf{$280\text{M}}$ (giving $D/E = 150 / 280 = 0.5357$).
2. MM Proposition II with Taxes: $$r_e = r_0 + (r_0 - r_d)(1 - t)\left(\frac{D}{E}\right) = 9.5% + (9.5% - 5.5%)(1 - 0.20)\left(\frac{150}{280}\right) = 9.5% + (4.0%)(0.80)(0.5357) = \mathbf{11.214%}$$
3. Post-Recapitalization WACC: $$\text{WACC} = \left(\frac{280}{430}\right)(11.214%) + \left(\frac{150}{430}\right)(5.5%)(1 - 0.20) = 7.302% + 1.535% = \mathbf{8.837%}$$

Problem 7 — CFA Level I (Session 2): Bond Duration & Convexity Price Approximation

Question: A bond currently trading at a full price of $$98.50$ has an Annual Modified Duration of $8.20$ and an Annual Convexity of $84.0$. If the bond's Yield to Maturity decreases by $125\text{ bps}$ ($\Delta\text{YTM} = -0.0125$), estimate the percentage change in the bond's full price and the new full price.

Solution:

1. Duration + Convexity Percentage Price Change Formula: $$\frac{\Delta P_{\text{Full}}}{P_{\text{Full}}} \approx -(8.20)(-0.0125) + \frac{1}{2}(84.0)(-0.0125)^2 = +0.10250 + 42.0(0.00015625) = +0.10250 + 0.00656 = \mathbf{+10.906%}$$
2. Estimated New Full Price: $$P_{\text{New}} = $98.50 \times (1 + 0.1090625) = \mathbf{$109.24}$$

---

Problem 8 — CFA Level I (Session 2): European Put-Call Parity & Arbitrage

Question: A non-dividend-paying stock trades at $S_0 = $85.00$. The annual risk-free rate is $r = 6.0%$. A 9-month ($T = 0.75$) European Put option with strike $X = $80.00$ trades at $p_0 = $3.10$. What is the no-arbitrage price of a 9-month European Call option with strike $X = $80.00$ ($c_0$)?

Solution:

1. Present Value of Strike Price $PV(X)$: $$PV(X) = \frac{$80.00}{(1.06)^{0.75}} = \frac{$80.00}{1.04467} = $76.58$$
2. Put-Call Parity ($c_0 + PV(X) = p_0 + S_0$): $$c_0 = p_0 + S_0 - PV(X) = $3.10 + $85.00 - $76.58 = \mathbf{$11.52}$$

---

Problem 9 — CFA Level I (Session 2): CAPM, Jensen's Alpha, Sharpe Ratio & $M^2$

Question: Over the past year, Portfolio Alpha returned $R_p = 15.2%$ with $\sigma_p = 18.0%$ and $\beta_p = 1.20$. The Market Portfolio returned $R_M = 11.5%$ with $\sigma_M = 14.0%$, and the risk-free rate was $R_f = 3.5%$. Calculate Portfolio Alpha's (a) CAPM expected return and Jensen's Alpha, and (b) Sharpe Ratio, Market Sharpe Ratio, and $M^2\text{ Alpha}$.

Solution:

1. CAPM Required Return & Jensen's Alpha: $$E(R_p) = R_f + \beta_p(R_M - R_f) = 3.5% + 1.20(11.5% - 3.5%) = 3.5% + 9.6% = \mathbf{13.10%}$$ $$\alpha_p = R_p - E(R_p) = 15.20% - 13.10% = \mathbf{+2.10%\text{ (+210 bps)}}$$
2. Sharpe Ratio & $M^2\text{ Alpha}$: $$\text{Sharpe}_p = \frac{15.2% - 3.5%}{18.0%} = \mathbf{0.650}, \qquad \text{Sharpe}_M = \frac{11.5% - 3.5%}{14.0%} = \mathbf{0.571}$$ $$M^2 = R_f + \text{Sharpe}_p \times \sigma_M = 3.5% + (0.650)(14.0%) = 3.5% + 9.1% = \mathbf{12.60%} \implies M^2\text{ Alpha} = 12.60% - 11.50% = \mathbf{+1.10%}$$

Problem 10 — AICPA CPA (FAR): ASC 842 Lessee Operating vs. Finance Lease Accounting

Question: On 1 January 2026, Lessee Corp enters into a 4-year equipment lease requiring four annual lease payments of $$30,000$ at the end of each year (31 December). The present value of the 4 payments at Lessee's $6.0%$ incremental borrowing rate is $$103,953$. The equipment has a fair value of $$160,000$, an economic life of 8 years, no purchase option, and no transfer of ownership. (a) Classify the lease under ASC 842. (b) Calculate Lessee Corp's 2026 Lease Expense, 31 December 2026 Lease Liability, and 31 December 2026 ROU Asset balance.

Solution:

1. Lease Classification ("OWNES"): No ownership transfer, no purchase option, $\text{PV}/\text{FV} = $103,953 / $160,000 = 65.0% < 90%$, $\text{Term}/\text{Life} = 4 / 8 = 50.0% < 75%$, non-specialized $\implies$ Operating Lease.
2. 2026 Income Statement & Balance Sheet Calculations:
   • 2026 Straight-Line Lease Expense: $\frac{4 \times $30,000}{4\text{ years}} = \mathbf{$30,000}$ (reported as a single operating expense; $$30,000$ cash paid is 100% CFO).
   • Interest Component on Lease Liability: $$103,953 \times 6.0% = $6,237$; Lease Liability principal reduction $= $30,000 - $6,237 = $23,763 \implies$ Ending Lease Liability $= $103,953 - $23,763 = \mathbf{$80,190}$.
   • ROU Asset Amortization (Plug): $\text{Straight-Line Lease Expense } ($30,000) - \text{Interest Component } ($6,237) = $23,763 \implies$ Ending ROU Asset $= $103,953 - $23,763 = \mathbf{$80,190}$.

Problem 11 — AICPA CPA (FAR / BAR): GASB Governmental Fund Accounting vs. Government-Wide Statements

Question: During fiscal year 2026, a city's General Fund levied $$10,000,000$ in property taxes: $$9,200,000$ was collected during 2026, $$450,000$ was collected in January and February 2027 (within 60 days of year-end), and $$350,000$ is expected to be collected in May 2027. Also during 2026, the General Fund paid $$600,000$ cash for new police patrol cars (5-year useful life, straight-line). How much Property Tax Revenue and Police Vehicle Expense/Expenditure are reported in 2026 on (a) the General Fund Statement of Revenues, Expenditures, and Changes in Fund Balance, and (b) the Government-Wide Statement of Activities?

Solution:

1. (a) General Fund (Current Financial Resources + Modified Accrual — 60-Day Rule):
   • Property Tax Revenue: Collected in 2026 ($$9,200,000$) $+$ collected within 60 days in Jan–Feb 2027 ($$450,000$) $= \mathbf{$9,650,000}$ (the remaining $$350,000$ is recorded as Deferred Inflows of Resources).
   • Capital Outlay Expenditure: $$600,000$ full expenditure in 2026 (no fixed assets or depreciation in GRASPP funds).
2. (b) Government-Wide Statement of Activities (Economic Resources + Full Accrual):
   • Property Tax Revenue: Full $$10,000,000$ levied (assuming $100%$ collectible).
   • Depreciation Expense: The $$600,000$ police cars are capitalized as Capital Assets and depreciated over 5 years $= \mathbf{$120,000}$ expense in 2026 (if purchased on Jan 1).

Problem 12 — AICPA CPA (AUD): Audit Risk Model, Assertions & Modified Opinion Matrix

Question: An auditor is auditing the financial statements of a manufacturing client whose ending inventory represents $45%$ of total assets. Management was hired AFTER year-end and prevented the auditor from observing the year-end physical inventory count, and no alternative audit procedures can satisfy the auditor regarding beginning or ending inventory quantities. Which audit opinion must the auditor express, and how does the Audit Report change?

Solution:

1. Nature of Issue: Inability to obtain sufficient appropriate audit evidence (Scope Limitation), NOT a known GAAP misstatement.
2. Materiality vs. Pervasiveness: Because inventory represents $45%$ of total assets and directly impacts Cost of Goods Sold, Gross Profit, Net Income, Retained Earnings, and Current Assets across multiple financial statements, the possible effects of undetected misstatements are both Material and Pervasive.
3. Required Opinion: Disclaimer of Opinion (the Opinion section is retitled "Disclaimer of Opinion on the Financial Statements" and states that because of the significance of the matter described in the Basis for Disclaimer of Opinion section, the auditor has not been able to obtain sufficient appropriate audit evidence to provide a basis for an audit opinion, and accordingly does not express an opinion on the financial statements).

Problem 13 — AICPA CPA (REG / TCP): C-Corp, S-Corp & Partnership Tax Basis Comparison

Question: Three equal ($1/3$) owners—A, B, and C—each contribute $$40,000$ cash to form a new business entity on 1 January 2026. On the same day, the entity borrows $$120,000$ on a recourse bank loan and incurs a $$210,000$ ordinary business operating loss during 2026. Assuming the at-risk and passive activity rules are met, how much of her $$70,000$ allocable share of the 2026 ordinary loss ($1/3 \times $210,000$) may Owner A deduct on her 2026 personal return if the entity is (a) a General Partnership vs. (b) an S Corporation?

Solution:

1. (a) General Partnership (IRC §§704(d) & 752):
   • Owner A's Outside Basis includes both her $$40,000$ cash contribution AND her $1/3$ share of the partnership's $$120,000$ recourse bank liability ($$40,000$) $= \mathbf{$80,000\text{ Outside Basis}}$.
   • Because $$80,000 \ge $70,000$, Owner A deducts the entire $$70,000$ loss in 2026 (leaving $$10,000$ ending outside basis).
2. (b) S Corporation (IRC §1366(d)):
   • An S Corporation shareholder receives ZERO basis from entity-level bank loans (even if personally guaranteed).
   • Owner A's Stock Basis is strictly her $$40,000$ cash contribution ($+\ $0\text{ Debt Basis}$), so she can deduct only $$40,000$ of the loss in 2026 (reducing her Stock Basis to $$0$, with the remaining $$30,000$ loss suspended and carried forward indefinitely).

Problem 14 — UK SRA SQE1 (FLK1): CPR Service Deadlines, Defence Filing & Part 36 Consequences

Question: A Claimant issues a Part 7 Claim Form (with Particulars of Claim attached) on Monday 2 March 2026 and posts it by first-class post to the Defendant on Tuesday 3 March 2026. (a) What is the date of deemed service of the Claim Form under CPR 6.14? (b) If the Defendant files an Acknowledgment of Service on 12 March 2026, what is the deadline for filing the Defence? (c) On 1 April 2026, the Claimant makes a valid Part 36 offer to settle for $\pounds 80,000$. The Defendant rejects the offer, and at trial the Claimant is awarded $\pounds 80,000$ in damages. What are the Part 36 consequences under CPR 36.17?

Solution:

1. (a) Deemed Service of Claim Form (CPR 6.14): Always the second business day after completion of the relevant step (posting on Tuesday 3 March) $\implies$ Thursday 5 March 2026.
2. (b) Deadline for Filing the Defence (CPR 15.4): Filing a timely Acknowledgment of Service (within 14 days of deemed service of the PoC) extends the Defence deadline to 28 days after deemed service of the Particulars of Claim $\implies 5\text{ March} + 28\text{ days} = \mathbf{\text{Thursday 2 April 2026}}$.
3. (c) Part 36 Consequences (CPR 36.17(1)(b) & (4)): Because the Claimant obtained a judgment ($\pounds 80,000$) at least as advantageous as (equal to or beating) the Claimant's own valid Part 36 offer ($\pounds 80,000$), from the expiry of the 21-day relevant period (22 April 2026) the court must (unless unjust) award the Claimant:
   • Indemnity basis costs from Day 22,
   • Enhanced interest on both the $\pounds 80,000$ damages and on those indemnity costs at up to 10% above base rate, AND
   • An additional monetary sanction of 10% of the damages awarded ($10% \times \pounds 80,000 = \mathbf{\pounds 8,000}$).

Problem 15 — UK SRA SQE1 (FLK1): Companies Act 2006 Directors' Transactions & Insolvency Act 1986

Question: Oakwood Ltd has net assets of $\pounds 600,000$. Its managing director, Sarah, wishes to sell her vintage car to Oakwood Ltd for $\pounds 75,000$. Sarah is also a director of Oakwood Ltd's parent company, Timber Holdings plc. (a) What approvals are required under the Companies Act 2006? (b) Eighteen months later, Oakwood Ltd goes into insolvent liquidation. Twenty months before the onset of insolvency, Oakwood Ltd had repaid an unsecured $\pounds 50,000$ loan to Sarah's husband while leaving trade creditors unpaid. Under which provision of the Insolvency Act 1986 can the liquidator challenge this repayment?

Solution:

1. (a) Substantial Property Transaction (s.190 CA 2006):
   • A non-cash asset acquired from a director is "substantial" if its value exceeds $\pounds 100,000$, OR exceeds $10%$ of the company's net asset value AND is more than $\pounds 5,000$. Here, $10% \times \pounds 600,000 = \pounds 60,000$, and $\pounds 75,000 > \pounds 60,000$, so it is a Substantial Property Transaction!
   • Under s.190, Sarah must first declare her interest to the boards (s.177) and obtain approval by Ordinary Resolution ($> 50%$) of the shareholders of BOTH Oakwood Ltd AND its holding company, Timber Holdings plc!
2. (b) Voidable Preference to a Connected Person (s.239 IA 1986):
   • Because Sarah's husband is an associate of a director (a connected person) under s.249/435 IA 1986, the relevant clawback period for a Preference under s.239 is 2 years (24 months) prior to the onset of insolvency (rather than 6 months for unconnected creditors), and the subjective desire to prefer is presumed under s.239(6) unless rebutted!

Problem 16 — UK SRA SQE1 (FLK2): Registered Land Overriding Interests & Overreaching

Question: Husband (H) and Wife (W) bought a registered freehold house together in 2018, with both contributing to the deposit, but legal title was registered in H's sole name. In 2025, while W is temporarily in hospital for a 10-day operation (with all her furniture, clothes, and family still in the house), H secretly sells and transfers the house to Buyer (B) for $\pounds 450,000$. B inspects the house while W is in hospital, sees women's clothing and family photos, does not ask H about anyone else having rights in the property, pays $\pounds 450,000$ to H alone, and registers the transfer at HM Land Registry. Does B take the house subject to W's equitable beneficial interest?

Solution:

1. Did Overreaching Occur (ss.2 & 27 LPA 1925)? NO. Overreaching requires paying the purchase money to at least two trustees or a trust corporation. Because B paid $\pounds 450,000$ to a single sole trustee (H), W's equitable interest under the constructive/resulting trust was NOT overreached (Williams & Glyn's Bank v Boland).
2. Does W Have an Overriding Interest under LRA 2002 Schedule 3 Paragraph 2? YES.
   • W holds a proprietary equitable interest under a trust of land.
   • Temporary absence in hospital with her belongings in the home and intention to return constitutes continuing actual occupation at the date of completion (Chhokar v Chhokar; Link Lending v Bustard).
   • Her occupation was obvious on a reasonably careful inspection (women's clothing and family photos), so neither Sch 3 Para 2 exception applies. Therefore, B is bound by W's beneficial interest.

Problem 17 — UK SRA SQE1 (FLK2) & SQE2: SRA Accounts Rules Double-Entry & Intestacy Distribution

Question: (a) A law firm holds $\pounds 3,000$ on Client Side for Client M. The firm pays a $\pounds 250$ HM Land Registry registration fee (which attracts no VAT) out of the firm's Business Bank Account because the cashier forgot to use the Client Account. Two days later, the firm sends Client M a bill for $\pounds 1,000$ profit costs plus $\pounds 200$ VAT and the $\pounds 250$ paid disbursement ($\pounds 1,450$ total) and transfers $\pounds 1,450$ from Client Account to Business Account. State the accounting entries. (b) Separately, T dies intestate in 2026 leaving an estate worth $\pounds 522,000$ (excluding $\pounds 15,000$ of personal chattels), survived by his Civil Partner (CP) and one 20-year-old daughter (D). How is T's estate distributed?

Solution:

1. (a) SRA Accounts Rules Entries:
   • Paying the $\pounds 250$ Land Registry fee from Business Account created a paid disbursement: DR Client M Ledger (Business Side) $\pounds 250$ / CR Cash Sheet (Business Account) $\pounds 250$.
   • Note that under Rule 4.3, the firm could actually reimburse the $\pounds 250$ paid disbursement immediately once incurred, and upon delivering the bill for $\pounds 1,000$ profit costs + $\pounds 200$ VAT (DR Client M Business Side $\pounds 1,200$ / CR Profit Costs $\pounds 1,000$ + CR VAT $\pounds 200$), the total Business Side debit balance is $\pounds 1,450$.
   • Transferring $\pounds 1,450$ from Client Account to Business Account: DR Client M Ledger (Client Side) $\pounds 1,450$ / CR Cash Sheet (Client Account) $\pounds 1,450$ AND CR Client M Ledger (Business Side) $\pounds 1,450$ / DR Cash Sheet (Business Account) $\pounds 1,450$ (leaving $\pounds 1,550$ on Client Side and $\pounds 0$ on Business Side).
2. (b) Intestacy Distribution (AEA 1925 s.46 — post-26 July 2023 Statutory Legacy $\pounds 322,000$):
   • Civil Partner (CP) receives: 1) All Personal Chattels ($\pounds 15,000$), 2) the $\pounds 322,000$ Statutory Legacy, and 3) 50% of the residue ($50% \times (\pounds 522,000 - \pounds 322,000) = 50% \times \pounds 200,000 = \pounds 100,000$), totaling $\pounds 422,000$ plus chattels.
   • Daughter (D) (aged $20 \ge 18$, so vested immediately) receives the remaining 50% of the residue $= \mathbf{\pounds 100,000}$.

Problem 18 — NCEES FE CBT: Mechanics of Materials (Mohr's Circle) & Fluid Mechanics (Darcy-Weisbach)

Question: (a) A machine shaft element experiences plane stress with $\sigma_x = +100\text{ MPa}$, $\sigma_y = +20\text{ MPa}$, and $\tau_{xy} = 30\text{ MPa}$. Find the maximum in-plane shear stress ($\tau_{\max}$) and the two principal stresses ($\sigma_1, \sigma_2$). (b) Water ($\nu = 1.0 \times 10^{-6}\text{ m}^2/\text{s}$) flows at $V = 3.0\text{ m/s}$ through a pipe of diameter $D = 0.15\text{ m}$ and length $L = 150\text{ m}$ with friction factor $f = 0.018$. Find the Reynolds number ($\text{Re}$) and head loss ($h_f$, using $g = 9.81\text{ m/s}^2$).

Solution:

1. (a) Mohr's Circle: $$\sigma_{\text{avg}} = \frac{100 + 20}{2} = +60\text{ MPa}, \qquad R = \tau_{\max} = \sqrt{\left(\frac{100 - 20}{2}\right)^2 + 30^2} = \sqrt{40^2 + 30^2} = \mathbf{50\text{ MPa}}$$ $$\sigma_1 = 60 + 50 = \mathbf{+110\text{ MPa}}, \qquad \sigma_2 = 60 - 50 = \mathbf{+10\text{ MPa}}$$
2. (b) Reynolds Number & Darcy-Weisbach Head Loss: $$\text{Re} = \frac{VD}{\nu} = \frac{(3.0)(0.15)}{1.0 \times 10^{-6}} = \mathbf{4.5 \times 10^5\text{ (Turbulent)}}, \qquad h_f = f\left(\frac{L}{D}\right)\left(\frac{V^2}{2g}\right) = 0.018\left(\frac{150}{0.15}\right)\left(\frac{3.0^2}{2 \times 9.81}\right) = 18(0.4587) = \mathbf{8.26\text{ m}}$$

Problem 19 — AACN CCRN: Swan-Ganz Hemodynamic Calculation & Shock Identification

Question: A 64-year-old patient admitted with urosepsis has the following hemodynamic parameters: Blood Pressure $= 78/42\text{ mmHg}$, Heart Rate $= 118\text{ bpm}$, $\text{CVP} = 2\text{ mmHg}$, $\text{PAP} = 22/9\text{ mmHg}$, $\text{PAWP} = 5\text{ mmHg}$, Cardiac Output ($\text{CO}$) $= 7.6\text{ L/min}$, $\text{SvO}_2 = 82%$, and serum lactate $= 4.6\text{ mmol/L}$. Calculate the patient's Mean Arterial Pressure (MAP) and Systemic Vascular Resistance (SVR), identify the exact shock state, and specify the first-line fluid and vasopressor resuscitation protocol.

Solution:

1. Mean Arterial Pressure (MAP): $$\text{MAP} = \frac{\text{SBP} + 2(\text{DBP})}{3} = \frac{78 + 2(42)}{3} = \frac{162}{3} = \mathbf{54\text{ mmHg}}\text{ (critically below }65\text{ mmHg target)}$$
2. Systemic Vascular Resistance (SVR): $$\text{SVR} = 80 \times \left(\frac{\text{MAP} - \text{CVP}}{\text{CO}}\right) = 80 \times \left(\frac{54 - 2}{7.6}\right) = \frac{4,160}{7.6} = \mathbf{547\text{ dyn}\cdot\text{s}\cdot\text{cm}^{-5}}\text{ (markedly below }800\text{–}1,200\text{ normal)}$$
3. Shock Diagnosis & Protocol: Low preload ($\text{CVP } 2, \text{PAWP } 5$), elevated hyperdynamic $\text{CO } (7.6\text{ L/min})$, high $\text{SvO}_2\text{ }(82%\text{ from impaired cellular oxygen extraction})$, and profoundly low $\text{SVR } (547)$ are diagnostic of Hyperdynamic (Warm) Distributive Septic Shock. Administer $30\text{ mL/kg}$ balanced IV crystalloid (Lactated Ringer's), draw blood cultures prior to giving broad-spectrum IV antibiotics within 1 hour, and titrate first-line IV Norepinephrine (Levophed) to maintain $\text{MAP} \ge 65\text{ mmHg}$ (adding fixed-dose Vasopressin $0.03\text{ units/min}$ second-line if needed).

Problem 20 — AANP / ANCC FNP Boards: Cardiorenal Pharmacology & Microcytic Anemia Differential

Question: A 58-year-old man with Type 2 Diabetes ($\text{HbA1c} = 7.9%$), Stage 3a CKD ($\text{eGFR} = 52\text{ mL/min/1.73 m}^2$, urine albumin-to-creatinine ratio $\text{UACR} = 180\text{ mg/g}$), and HFrEF ($\text{LVEF} = 35%$) is currently taking Metformin $1,000\text{ mg BID}$ and Lisinopril $20\text{ mg daily}$. (a) To optimize his HFrEF and diabetic CKD mortality under ACC/AHA and ADA guidelines, his FNP switches Lisinopril to Sacubitril/Valsartan and adds three additional foundational medications. Name the classes/agents and the mandatory transition rule. (b) Routine CBC reveals a new microcytic anemia: $\text{Hb} = 10.2\text{ g/dL}$, $\text{MCV} = 71\text{ fL}$, $\text{RBC} = 3.6 \times 10^6/\mu\text{L}$, $\text{RDW} = 17.8%$, and $\text{Ferritin} = 8\text{ ng/mL}$. What is the diagnosis and mandatory next diagnostic step?

Solution:

1. (a) HFrEF & Diabetic CKD Quadruple GDMT:
   • Mandatory Transition Rule: Hold Lisinopril (ACEi) for a strict 36-hour washout period before initiating Sacubitril/Valsartan (ARNI) to prevent life-threatening bradykinin angioedema.
   • Add the remaining 3 HFrEF GDMT Pillars: 1) an evidence-based Beta-Blocker (Carvedilol, Metoprolol Succinate ER, or Bisoprolol), 2) a Mineralocorticoid Receptor Antagonist (Spironolactone or Eplerenone, monitoring $\text{K}^+$ and $\text{eGFR}$), and 3) an SGLT2 Inhibitor (Dapagliflozin or Empagliflozin)—which simultaneously reduces HFrEF mortality, slows diabetic CKD progression, and lowers HbA1c.
2. (b) Microcytic Anemia in an Adult Male:
   • Low MCV ($71\text{ fL}$), low Ferritin ($8\text{ ng/mL}$), elevated RDW ($17.8%$), and Mentzer Index $= 71 / 3.6 = 19.7 > 13$ confirm Iron Deficiency Anemia (IDA) (not Thalassemia trait).
   • Mandatory Next Step: In any adult male or postmenopausal woman, new-onset Iron Deficiency Anemia is occult gastrointestinal blood loss (colorectal malignancy) until proven otherwise—refer immediately for bidirectional GI endoscopy/colonoscopy alongside oral iron replacement.
