Balance sheet and funding
ALM, cash flows and funding costs.
APPLIED RESEARCH · BANKING MANAGEMENT
Banking Management Lab
Connect performance, funding, liquidity and capital before approving a business decision. Explore the management framework, then open the relevant existing tool and review its assumptions and limitations.
Scope and decision framework
Why this laboratory?
A banking decision affects income, funding, liquidity and capital together. This laboratory brings these dimensions together to examine balance-sheet trade-offs and their consequences. It connects quantitative and risk tools with management questions.
Ambition with discipline
The tools present educational scenarios and simplified conventions. A result alone establishes neither profitability, soundness nor compliance of an institution. A real decision needs reconciled data, a defined accounting perimeter and documented funding assumptions.
Performance and capital
Income, capital allocation and liquidity constraints.
Financing structures
Credit, securitisation and Islamic-finance scenarios.

Piloter la banque au-delà du volume commercial
Une activité peut gagner des clients tout en consommant trop de liquidité, de capital ou de capacité opérationnelle. Le pilotage rapproche donc proposition de valeur, économie du bilan et qualité du service. Les cadres ci-dessous sont une synthèse appliquée des ouvrages, sans objectifs chiffrés de performance.
Lire la performance sans masquer le risque
Le produit net bancaire ne suffit pas à apprécier une activité. Le comité suit aussi les charges, le coût du risque, les revenus récurrents et le capital mobilisé. Le coefficient d’exploitation aide à lire l’efficacité, mais sa comparaison exige un périmètre homogène : acquisitions, coûts de transformation et externalisations peuvent modifier sa signification. Une amélioration ponctuelle doit être rapprochée de la qualité du service et des risques différés.
CoEx = charges d’exploitation / produit net bancaire
Application et points de vigilance
Pour une activité de crédit, expliquer séparément l’évolution des volumes, de la marge, des défauts et des coûts. Le tableau de bord nomme un responsable, une fréquence de revue et une action possible pour chaque indicateur. Un ratio isolé ne devient pas automatiquement une cible.
Séparer marge commerciale et transformation
Le taux de cession interne attribue aux métiers un coût ou une rémunération de financement. Il rend visibles les responsabilités de la collecte, de l’octroi et de la trésorerie. La méthode doit être cohérente avec la maturité, la devise, la liquidité et les options contractuelles. Un taux unique peut fausser les comparaisons et les incitations ; la convention retenue doit être documentée et réconciliée avec le résultat consolidé.
Application et points de vigilance
Une collecte stable et un dépôt volatil ne reçoivent pas nécessairement la même rémunération interne. Pour un crédit remboursable par anticipation, expliciter qui porte l’option et son coût ; éviter de facturer deux fois le même risque entre trésorerie et métier.
Organiser le parcours client et la contradiction
La relation client ne se réduit pas à la vente : elle engage la qualité des données, la compréhension du besoin, la continuité du service et le traitement des incidents. Les objectifs commerciaux doivent être accompagnés de contrôles et de responsabilités explicites. Une organisation efficace précise les décisions du métier, les avis indépendants du risque et les validations de conformité, puis traite les désaccords avant l’exécution.
Application et points de vigilance
Lors d’un lancement, réunir métier, opérations, risque et finance autour d’un dossier unique : clientèle visée, économie du produit, exceptions, réclamations et capacité de traitement. Les améliorations sont testées sur des faits observables, sans promettre de gain non mesuré.
Balance-sheet steering: earnings and economic value
Review the same balance sheet through two complementary lenses. Net interest income measures earnings over a planning horizon; economic value measures the present value of asset and liability cash flows. Protecting short-term earnings can leave economic value exposed. An ALCO review should connect repricing buckets, deposit behaviour, basis risk and embedded options to the chosen hedge.
\begin{aligned}\mathrm{NII}&=I_{\mathrm{income}}-I_{\mathrm{expense}}\\\Delta\mathrm{EVE}&\approx-\frac{D_AA-D_LL}{1+y}\Delta y\end{aligned}
Assumptions, controls and source
The duration approximation assumes a small parallel shift, stable cash flows and a common yield convention. It excludes behavioural changes, convexity and non-parallel movements. Compare NII and EVE scenarios on documented balance-sheet assumptions; neither is a liquidity reserve.
Rose & Hudgins, Bank Management & Financial Services, 9th ed., ch. 7, pp. 226–234, 238–246 (PDF 256–264, 268–276).
Liquidity: forecast, reserve and contingency actions
Build a dated sources-and-uses forecast: deposit flows, credit-line drawdowns, repayments, debt maturities, collateral calls and operating payments. Separate the planned funding requirement from a protective reserve for forecast error. Review idiosyncratic, market-wide and combined scenarios. Each available financing or asset-sale action needs an owner, lead time and execution constraint.
L_t=\mathrm{Inflows}_t-\mathrm{Outflows}_t
Assumptions, controls and source
A projected inflow is not immediately available funding. Separate committed facilities, contingent sources, encumbered assets and sale proceeds subject to haircuts. Do not assume stress-market access or central-bank support. Reserve sizes and escalation triggers require bank-specific approval, not a universal threshold.
Rose & Hudgins, ch. 11, pp. 360–368 (PDF 390–398). BCBS, Principles for Sound Liquidity Risk Management and Supervision (2008), principles 10–12.
Capital allocation: RAROC and economic profit
Use RAROC to compare relative performance and economic profit to measure value in currency terms. Reconcile accounting income to expected net earnings, including risk costs and documented adjustments. Compare activities on a common horizon and economic-capital method. A lower RAROC alone does not justify closing a positive-economic-profit activity; assess feasible alternative uses of released capital.
\mathrm{RAROC}=\frac{\mathbb E[\Pi_{\mathrm{net}}]}{EC},\qquad EP=\mathbb E[\Pi_{\mathrm{net}}]-kEC
Assumptions, controls and source
Economic capital depends on the loss model, horizon, aggregation and allocation convention; it differs from available and regulatory capital. Avoid counting the same capital cost in both net earnings and kEC. RAROC does not describe funding liquidity or tail risk completely.
de Weert, Bank and Insurance Capital Management, ch. 18, pp. 171–175, eq. 18.1 p. 174 (PDF 189–193).
Credit pricing: explain the economics of a quote
Explain a loan quote through funding, operating cost, credit-risk compensation and margin. Document maturity, collateral, borrower quality and the wider relationship. The commercial committee reviews deviations alongside risk and finance. Trace the cost allocation and expected-loss convention before approving a pricing exception.
r_{\mathrm{quote}}=c_{\mathrm{funding}}+c_{\mathrm{operations}}+s_{\mathrm{credit}}+m
Assumptions, controls and source
Cost-plus is a decision aid, not proof that the borrower accepts the quote or that the loan remains profitable under stress. The credit premium is not automatically expected loss. Explain treatment of uncertainty, capital costs and collateral before comparing quotes; avoid duplicate costs across FTP and business margin.
Rose & Hudgins, ch. 17, pp. 577–578 (PDF 607–608).
Strategy–risk–capital: a documented decision cycle
Translate strategy into business objectives and capital allocation; evaluate risk and economic profit, then revise allocation and strategy. Each decision records evidence, a responsible owner, approval and a review date. Operational control supports execution; independent audit assesses the control system.
Committee decision record
For ALCO, record funding assumptions, hedging rationale, treasury execution owner and risk challenge. For credit, record borrower analysis, price deviations and approving authority. For capital allocation, record alternative uses and review economic profit. For operational incidents, name the process owner and verify closure evidence. This is an adaptable responsibility template, not an assertion about a bank’s actual organisation.

EVIDENCE AND CONTROLS
Integration: carry the investment thesis into execution
The integration plan should retain the strategic and financial objectives used to approve the investment. Separate business continuity from incremental synergies, while recognising that both rely on shared people, systems and decisions. For each initiative, define its owner, milestone, one-time cost, expected benefit and verification measure. A leadership summary should expose dependencies and risks across functional plans, rather than present a collection of disconnected schedules. Customer retention, operating capability and culture may matter alongside financial savings. Compare delivery with the original baseline, then explain changes in scope or timing. Benefits that were already included in standalone forecasts should not be counted again as synergies. Targets remain plans until supporting results are observed and reconciled.
Scope, limitations and source
Synergy targets remain plans until supported by reconciled delivery evidence. Benefits already included in standalone forecasts must not be counted twice.

DECISION FRAMEWORK
Profit does not settle the liquidity question
Revenue recognition and cash collection can occur in different periods. Read profit together with changes in receivables, inventories, payables and non-cash charges. Then distinguish operating cash from investment and financing flows. For a project or new activity, a dated cash plan should show the financing gap before income becomes cash. Runway is conditional on the assumed collection dates and spending profile; fresh borrowing may extend liquidity without improving operating profitability.
Decision, data and controls
Decision: Match the funding plan to the cash gap. Data: Collection dates, payment dates, opening cash and committed financing. Control: Reconcile profit-to-cash adjustments and separate financing from operations.
Scope, limitations and source
Project-finance reasoning, not a substitute for a bank liquidity framework or a forecast based on live data.
Harvard Business Review (2018), Appendix A, printed pp236-240 / PDF pp246-250, particularly p239 / PDF p249.
EVIDENCE AND CONTROLS
Culture as an integration dependency
Cultural integration becomes concrete when it concerns decision rights, working practices, language and employee expectations. Identify where the two organizations use different routines and where that difference could disrupt customer service or cooperation. Design communication and joint working around those dependencies rather than relying on a statement that the cultures are compatible. Respect for both organizations does not imply that every practice should remain unchanged. The integration plan must connect the desired operating model to responsibilities and observable milestones.
Decision, data and controls
Decision: Decide which routines to retain, adapt or combine. Data: Decision rights, communication routes, working practices and staff feedback. Control: Assign owners and observe operational consequences, not culture labels alone.
Scope, limitations and source
Management mechanism, not a quantified causal estimate of merger success or a staffing/legal instruction.
Moeller and Brady (2007), ch10, printed pp250-253 / PDF pp267-270. Avoid dated case percentages and blanket cultural stereotypes.

ALM : distinguer revenu, valeur et liquidité
Un même choc de taux peut améliorer le revenu à court terme et réduire la valeur économique du bilan. Les pricers ALM se lisent à travers ces deux horizons, avec une troisième question : les flux de trésorerie restent-ils finançables ?
Revenu : le calendrier de révision des taux
L’écart de révision compare les actifs et les passifs dont le taux peut évoluer sur un horizon donné. Une approximation linéaire suppose des révisions simultanées et une transmission comparable du choc. En pratique, les taux des dépôts réagissent partiellement, les courbes se déplacent différemment et les volumes peuvent changer. La projection du revenu net d’intérêts doit donc annoncer ses conventions de bilan constant ou dynamique.
ΔNII ≈ (Ar − Lr) × Δr × H
Application et points de vigilance
Comparer choc parallèle, pente et base, puis faire varier la transmission aux dépôts. Présenter séparément les encours déjà contractés et la nouvelle production. La sensibilité n’est ni une prévision de marché ni un revenu garanti.
Valeur : la duration et ses limites
La valeur économique rapproche la valeur actualisée des actifs et des passifs. La duration modifiée donne une sensibilité locale à un petit choc parallèle ; elle ne décrit pas correctement, seule, les mouvements de pente, la convexité ou les options. Les remboursements anticipés et la stabilité des dépôts nécessitent des hypothèses comportementales, dont les effets doivent être confrontés à plusieurs scénarios.
ΔEVE ≈ −(DAmod A − DLmod L) Δy
Application et points de vigilance
Pour un portefeuille de crédits fixes financé par des dépôts, rapprocher ΔEVE et ΔNII. Tester un allongement ou un raccourcissement de la vie des dépôts et une variation des remboursements anticipés avant de conclure sur la couverture.
Liquidité : financer les échéances réelles
Une banque solvable peut subir une tension de trésorerie. La lecture ALM complète les sensibilités de taux par les échéances de financement, les sorties de dépôts, les appels de marge et la disponibilité des garanties. Les actifs mobilisables ne sont pas équivalents à des liquidités immédiatement disponibles : délais, décotes, devise et contraintes de transfert comptent.
Application et points de vigilance
Un scénario de hausse des taux peut combiner retraits de dépôts et besoins de collatéral. Le comité documente les ressources disponibles, les coûts et les actions déclenchées ; il ne confond pas une sensibilité de prix avec une mesure de survie en liquidité.

BANKING · CONTRACTS AND GOVERNANCE
Islamic finance: contracts, risks and decisions
Read the contract before interpreting the return. This educational section connects financing structures to cash flows, evidence and review responsibilities.
No Sharia ruling, certification, investment recommendation or local legal assessment is provided. Applicability depends on the contract, jurisdiction and competent authorities.
Open the 3D demonstratorsMurabaha · cost and sale price
A sale at disclosed cost plus an agreed margin.
Review questions and proposed work
Proposed review: reconcile purchase, ownership evidence, resale and instalments. Separate the inventory period from the customer receivable. Retain the supplier invoice and agreed price; a margin alone does not establish compliance.
P=C+M
P: agreed sale price; C: disclosed acquisition cost; M: agreed margin. All three amounts use the same currency. This identity is not an annual yield or a pricing model.
Ijara · use and ownership
A lease of an asset’s usufruct for agreed rent.
Review questions and proposed work
Proposed review: document the asset, availability, rental schedule, maintenance responsibilities and any separate transfer undertaking. Build a cash-flow map before discussing valuation; do not equate a lease label with an IFRS classification or a Sharia ruling.
Musharaka · partnership capital
Partners contribute capital; profits follow agreed ratios and losses capital shares.
Review questions and proposed work
Proposed review: reconcile contributions, profit definitions, valuation dates, distributions and exit clauses. Keep investment loss separate from loss attributed to a contractual breach. A projected distribution is not a guaranteed return.
Mudaraba · capital and management
Capital and management come from different parties; profits are shared.
Review questions and proposed work
Ordinary investment loss falls on the capital provider; misconduct, negligence or contractual breach require separate assessment. Proposed review: preserve the profit-sharing agreement, manager reports and attribution of expenses. Distinguish investment accounts from an automatically guaranteed deposit.
Salam and istisna · delivery risk
Salam uses advance payment for future delivery; istisna concerns manufacture or construction.
Review questions and proposed work
Proposed review: specify quality, quantity, delivery dates, acceptance and supplier exposure. Map each parallel contract independently; a matching schedule does not by itself cancel an obligation. Review delay and replacement-cost scenarios, without assuming a regulatory risk weight.
Sukuk · follow rights and recourse
The underlying structure determines the rights represented by the certificates.
Review questions and proposed work
Proposed review: map the issuer, vehicle, assets, distributions, servicing and purchase undertakings. Test ownership and recourse against the documents; do not infer asset-backed protection from the word sukuk. Compare cash-flow scenarios on a common currency and horizon, with a documented valuation method.
Liquidity and ALM · contractual cash flows first
Funding capacity and saleability need their own review.
Review questions and proposed work
Proposed analysis: build contractual and stressed cash-flow ladders, identify withdrawal assumptions, eligible instruments and concentrations. Record any assumed secondary-market access. Existing conventional ALM tools may illustrate arithmetic only; they do not establish Sharia eligibility, a tradable hedge or compliance with a liquidity ratio.
Governance · evidence, responsibilities and review
Separate product economics, Sharia review, accounting and local regulation.
Review questions and proposed work
Proposed deliverable: a responsibility matrix and evidence file covering contract versions, approval, execution checks, exceptions and escalation. Record the competent Sharia authority and the standard actually adopted. AHS proposes analytical and process support; this page claims no Sharia certification, religious ruling or completed client mandate.
ISLAMIC FINANCE · CASH FLOWS AND 3D SCENARIOS
Islamic finance: explore cash flows in 3D
Seven educational demonstrators comparing prices, rents, outcome allocation, ownership and delivery. Surfaces are calculated from entered assumptions, not market observations.
Simplified models, no religious ruling or Sharia certification. Contract terms, ownership rights, jurisdiction and specialist validation require review for any actual transaction. No client outcome or guaranteed return claimed.

BANQUE · CADRES DE DÉCISION
Capital : relier risque, rendement et capacité de décision
Le capital comptable, le capital réglementaire et le capital économique répondent à des questions différentes. Le pilotage gagne à les rapprocher sans les rendre interchangeables.
Trois lectures du capital
Les fonds propres comptables résultent du référentiel et du périmètre de consolidation. Le capital réglementaire dépend des critères d’éligibilité et des règles applicables. Le capital économique représente une estimation interne de pertes inattendues à un horizon et un niveau de confiance définis. Leur réconciliation doit identifier les déductions, les risques couverts et les contraintes de disponibilité entre entités ; un agrégat groupe ne prouve pas que les ressources sont transférables.
Application et points de vigilance
Pour un groupe banque-assurance, vérifier les participations croisées, les contraintes locales et le double emploi potentiel des ressources. Les développements réglementaires du livre de 2011 sont historiques ; utiliser le texte actuel pour déterminer les exigences effectivement applicables.
RAROC : une convention à expliciter
Un rendement ajusté du risque rapproche le résultat attendu et le capital économique alloué. Le numérateur doit préciser les charges de financement, les coûts opérationnels, les pertes attendues et le traitement fiscal. Le dénominateur dépend du modèle et de l’allocation de diversification. Comparer des métiers sans conventions homogènes peut récompenser une sous-estimation du risque plutôt qu’une création de valeur.
RAROC = résultat net attendu / capital économique
Application et points de vigilance
Dans un arbitrage de portefeuille, présenter le RAROC central et stressé avec les besoins de liquidité et les limites de concentration. Une hausse du ratio obtenue par réduction du capital modélisé appelle une revue indépendante. Aucun seuil universel n’est proposé.
Du stress test à l’action de management
Un stress test utile ne se limite pas à un chiffre de perte. Il explicite le scénario, les interactions entre revenus, défauts, financement et collatéral, puis les décisions possibles. Les actions doivent être faisables dans l’horizon retenu et leurs coûts visibles. La validation examine les hypothèses comportementales, les effets de second tour et les risques de double comptage entre provisions et mesures de capital.
Application et points de vigilance
Pour une activité concentrée, tester conjointement hausse de PD, baisse des recouvrements et refinancement plus coûteux. Le dossier présente l’impact, les incertitudes, le responsable de la décision et les critères de réexamen.

Cadre Bâle et outils existantsComptabilité des instruments financiersEVIDENCE AND CONTROLS
Separate control design from operating effectiveness
A well-written control may still fail if it is not performed at the right time or on the right population. Assess design and execution separately: identify the risk the control addresses, then inspect evidence that it operated as intended. Keep exceptions, root causes and remediation owners linked to the original risk. Set a realistic completion date and an escalation route for overdue actions. A heat-map score supports prioritisation, but an ordinal rating is not a calibrated probability of breach, an expected loss or a capital amount. Re-test the corrected process before closing the finding.
Decision, data and controls
Decision: accept the evidence or reopen remediation. Data: documented design, execution samples, exceptions, due dates and re-test results. Control: distinguish a designed control from a tested control; define score scales before aggregating them.
Scope, limitations and source
Qualitative control ratings are not monetary prices, breach probabilities or regulatory capital. No score-to-loss conversion is added.

BASEL / PRUDENTIAL FRAMEWORK
Basel: connect requirements to balance-sheet management
Capital absorbs losses; liquidity supports payment obligations; governance makes measures controllable. Read these dimensions together, with an explicit perimeter and date.
Pillar 1 · Measure
Identify eligible capital and adjustments, then credit, market and operational RWA. Counterparty exposures and CVA risk have specific treatments. Basic BCBS minima are 4.5% CET1, 6% Tier 1 and 8% total capital; buffers and additional requirements depend on the applicable framework.
Pillar 2 · Assess
Connect material risks, loss-absorbing capacity and capital planning to supervisory review. Stress scenarios, concentration and banking-book interest-rate risk are not reducible to a Pillar 1 ratio. Document decisions and challengeable assumptions.
Pillar 3 · Disclose
Reconcile prudential measures, financial statements and published disclosures. Transparency requires stable definitions, traceable method changes and validated data quality. Comparisons across banks must account for perimeter and method differences.
International standards and European law
BCBS standards are not, by themselves, directly applicable law. In the European Union, CRR3 — Regulation (EU) 2024/1623 — amends CRR; CRD6 — Directive (EU) 2024/1619 — amends CRD and requires national transposition. Operational interpretation must check consolidated versions, transitional provisions, the entity, consolidation level and supervisory decisions.
From rule to control: accountability chain
- Set scope: entity, jurisdiction, consolidation, date and legal version.
- Qualify data: capital eligibility, exposures, collateral, maturities and liquidity aggregates.
- Identify approaches: standardised or authorised models; review assumptions and changes.
- Reconcile: source data → calculations → prudential reports → disclosure; retain an audit trail.
- Assign validation: Finance, Risk, compliance and governance; define escalation and review.
How to read the simulations
Surfaces vary two aggregates while all other inputs remain fixed. The 72.5% floor target is a fully phased scenario. A ratio increase caused by a lower denominator does not alone demonstrate improved resilience: explain it through exposures, methods and possible disposals.
These tools compute relationships using supplied amounts. They are not a full RWA engine, regulatory reporting system or compliance certification.
Basel calculators
Interpret the result before deciding
Compare scenarios using consistent currency, horizon and accounting conventions. Distinguish an illustrative model output from an approved business target. Identify the decision owner, independent review and escalation route; retain the assumptions and evidence supporting the decision.

Continue with the six currently published Management notes. The research selection and publication status are unchanged.
RESEARCH NOTE · ORIGINAL SYNTHESIS
Tax, financing and cash-flow dates
Selected readings from the supplied books, connected to reviewable decisions. Historical analysis, model assumptions, author proposals and applicable law are kept distinct.
Educational research, not an entity-specific tax opinion. Local rules, treaties and effective dates require separate specialist review. No client results or tax savings are claimed.
Open seven tax demonstratorsTax payment dates change present value
Can identical nominal taxes have different discounted costs?
Brusov and Filatova make payment frequency and advance versus end-period timing explicit in their capital-structure models. The transferable insight is to date cash flows before discounting them. The demonstrator below isolates that timing effect for a fixed nominal annual tax budget. It is an original finite cash-flow illustration, not an implementation of the book’s perpetual tax-shield or BFO equations.
Proposed application and review limits
Decision and deliverable
Proposed review: reconcile tax accrual, cash payment dates, usable deductions and the discount-rate convention. Compare identical nominal totals; distinguish a payment brought forward from a reduction in tax due.
Assumptions and limits
No freedom to choose statutory due dates is assumed. Timing does not create a deduction or reduce the legal tax liability.

Finite horizon, tax shield and terminal value
Which assumptions allow a financing tax benefit to enter valuation?
The book contrasts finite-horizon BFO formulations with perpetual limits and varies income and payment timing. These are model-dependent results. For a valuation review, make debt policy, taxable capacity, cash-flow risk, horizon and terminal assumptions explicit. Do not add a separately valued tax shield to cash flows already discounted at a rate that includes the same tax benefit.
Proposed application and review limits
Decision and deliverable
Proposed deliverable: assumption bridge between an unlevered value, financing effects and a WACC valuation. Explain any difference before selecting a method; no universal superiority of BFO is claimed.
Assumptions and limits
Constant capital weights, full usability of interest deductions and a single rate are restrictive assumptions. The book’s model results are not an empirical validation for a client.
WACC=w_E k_E+w_D k_D(1-\tau),\quad w_E+w_D=1
w_E,w_D: market-value weights; k_E,k_D: annual required returns as decimals; τ: assumed usable tax rate, dimensionless. WACC is an annual rate; the formula does not estimate its inputs.

Cost of equity is not a dividend instruction
How should a model result inform a distribution decision?
Chapter 22 connects tax burden, leverage, horizon and the modelled cost of equity to dividend-policy discussion. Treat that link as the authors’ analytical framework. A required return is not automatically a cash distribution: retained earnings, investment needs, liquidity, solvency and legal restrictions require separate review. A negative or declining model output needs interpretation, not automatic execution.
Proposed application and review limits
Decision and deliverable
Proposed deliverable: distribution scenarios reconciled with available cash and investment commitments, plus documented decision gates. Keep the financial sensitivity and the legally distributable amount separate.
Assumptions and limits
No dividend entitlement, authorised distribution or local corporate-law test is determined by this note.

Teaching demonstrator: tax payment dates
Compare equal nominal annual payments at different dates. Synthetic monetary units (MU), flat effective annual discount rate, no tax assessment or BFO implementation. Initial values are illustrative.
PV = sum of discounted payments
A: fixed annual tax budget (MU/year); p: payments per year; n: whole years; r: effective annual discount rate (decimal). Each payment A/p occurs at t_j=(j+1)/p at period-end or j/p in advance, j=0,…,np−1. No growth, inflation, default, deduction limit or statutory instalment rule is modelled.
With a positive rate, earlier payment increases the present cost of a fixed tax outflow. This does not imply that tax deductions or an entire financed company have the same sensitivity. The dates are hypothetical; they are not selectable statutory deadlines.
