Decision brief

Your assignment

Role: Senior accounting analyst supporting Linden Peak's controller, treasury group, valuation specialist, investment committee, and audit committee

Deliverable: A security-level portfolio close with scope and evidence cards, debt amortized-cost and classification bridges, credit and fair-value layers, sale and transfer controls, ordinary-equity schedules, significant-influence memorandum, equity-method basis rollforward, hierarchy assessment, entries, disclosure support, currentness register, exception log, and release recommendation

Evidence basis: fictional

Visible standard

Evaluation criteria

  • technical accuracy (30%): Recomputes interest, amortized cost, credit and fair-value bridges, listed and private equity measurements, equity-method income, basis effects, dividends, OCI, carrying amounts, and entries without netting or double counting.
  • scope and evidence (30%): Preserves instrument rights, classification and influence support, valuation and credit ownership, election evidence, sale and transfer dates, current authority, proposal-stage warnings, and unresolved stop conditions.
  • articulation and controls (20%): Connects custody, quantities, each basis layer, earnings, OCI/AOCI, ledger balances, statements, disclosures, and sign-offs through security-level reconciliations.
  • interpretation and communication (20%): Explains why identical cash flows can report differently and why observability, influence, credit, fair value, dividends, and project status are not interchangeable labels.

Your role and release question

Linden Peak is closing a portfolio that treasury maintains in one spreadsheet. The file sends every unrealized change to OCI, labels a bond HTM because a manager typed “collect,” leaves private shares at cost, records Harbor's dividend as income, and calls every modeled price Level 3. Decide what can be released, what requires correction, and what must remain with an accountable reviewer.

Fictional evidence packet

The packet includes custodial statements; contracts and security identifiers; investment-strategy approvals; HTM, AFS, and trading memoranda; market quotes; yield support; a credit memorandum; sale confirmations; a classification- transfer memorandum; listed-share market data; a private-share election, impairment review, and same-issuer transaction file; Harbor's ownership ledger, board materials, intercompany activity, audited statements, dividend notice, OCI detail, and acquisition-date basis schedule; valuation technique and input inventories; general-ledger detail; draft disclosures; and a standards clock.

Some evidence is deliberately incomplete. The HTM memo omits a recent sale. The AFS credit file lacks final approval. One quoted price is for a similar, not identical, instrument. Private-share rights differ from the observed transaction and lack a comparability conclusion. Harbor's equipment basis life is supplied, but the valuation sign-off is absent. A draft memo cites May and July 2026 proposal-stage materials as current guidance.

Required work

  1. Build one instrument, rights, scope, conclusion, evidence-owner, and exception card per holding.
  2. Reperform the identical-bond amortized-cost row and prove which values remain invariant across classifications.
  3. Reconcile HTM gross amortized cost, allowance, and net reported amount.
  4. Reconcile AFS amortized cost through its separately supplied credit and noncredit OCI layers to fair value; withhold the unapproved credit amount.
  5. Route trading fair-value change to earnings while preserving interest revenue as a separate line.
  6. Update and derecognize the sold security's identified units and all applicable layers; control AOCI and avoid double counting.
  7. Evaluate the supported transfer at its date under current guidance without rewriting earlier history.
  8. Reconcile listed shares at fair value through earnings and private shares under the supplied measurement-alternative election; stop at missing comparable-rights evidence.
  9. Prepare a significant-influence memorandum that weighs ownership and qualitative evidence and distinguishes influence from control.
  10. Reperform Harbor's share of results, assigned basis effects, dividends, OCI, and ending carrying amount; identify the missing valuation approval.
  11. Classify each supplied fair-value measurement by its lowest-level significant input and explain why hierarchy is not an asset-quality grade.
  12. Reconcile custody to ledger to statements, attach disclosure and currency support, and give a release, release with disclosure, withhold, or route decision for each instrument.

Constraints and failure conditions

Use only supplied fictional facts and named authority records. Do not provide legal, tax, investment, or valuation advice. Withhold the package if it:

  • uses one measurement route for all holdings or reverses issuer entries mechanically;
  • infers HTM or influence from a label or percentage;
  • skips effective interest or nets AFS credit with noncredit change;
  • sends Topic 321 listed-share changes to OCI or freezes the measurement alternative at cost;
  • recognizes equity-method dividends as ordinary income or calls all basis excess goodwill;
  • equates Level 3 with poor asset quality; or
  • treats a proposal as current GAAP.
