Sources & Attestation

Every statement, framework, and example in this handbook derives from publicly available accounting standards, professional project-management bodies of knowledge, regulatory guidance, industry publications, and the author's independent practitioner analysis. No proprietary, confidential, or employer-specific material is included.

📜 Author Attestation

I, Nico Rivera, attest that the content of this handbook reflects publicly available information, generalized industry concepts, and my independent analysis. It does not reproduce, reference, or disclose proprietary information, confidential operating data, internal policies, internal systems documentation, trade secrets, or any materials from any past or present employer. Illustrative numbers, worked journal entries, and example SOX control language are hypothetical and constructed to demonstrate accounting mechanics and control design — not derived from any proprietary dataset.

Public Sources Used

This handbook is built on information drawn exclusively from the following categories of public sources. Every accounting treatment, technical framework, journal entry illustration, SOX control example, vendor assessment, and operational description traces back to one or more of these.

1. US GAAP & Accounting Standards

Content referencing accounting standards is sourced from the FASB Accounting Standards Codification, publicly accessible at asc.fasb.org. Standards referenced include:

  • ASC 606 — Revenue from Contracts with Customers (five-step model, SSP, contract modifications)
  • ASC 450 — Contingencies (loss contingency reserves, operational loss frameworks)
  • ASC 326 — Financial Instruments — Credit Losses (CECL methodology, model governance)
  • ASC 815 — Derivatives and Hedging (commodity and partnership hedge accounting)

  • ASC 340-40 — Contract Costs (incremental costs of obtaining a contract)
  • ASC 805 — Business Combinations (M&A accounting, carve-out financial statements)
  • ASU 2016-13 — CECL transition and adoption guidance

2. Professional Standards & Bodies of Knowledge

Project management, audit, and internal control framework references draw from publicly published professional bodies:

  • PMI® PMBOK® Guide — Project Management Body of Knowledge (Project Management Institute, public distribution)
  • COSO Internal Control — Integrated Framework (2013) — the SOX control framework standard
  • PCAOB Auditing Standards — publicly available at pcaobus.org
  • AICPA technical guidance — publicly published audit and accounting guides
  • IIA IPPF — International Professional Practices Framework for internal audit

3. Regulatory & Government Sources

  • SEC EDGAR public filings (10-K, 10-Q, 8-K) from publicly traded companies across industries
  • SEC Staff Accounting Bulletins (SABs) and interpretive guidance
  • Federal Reserve supervisory guidance (SR letters) relevant to financial institution accounting
  • OCC and FDIC examination manuals and guidance (publicly distributed)
  • Sarbanes-Oxley Act of 2002 and related SEC implementation rules
  • IRS publications on partnership taxation (Form 1065, Schedule K-1 instructions)

4. Industry Publications & Vendor-Published Materials

  • Big 4 public accounting and advisory publications (Deloitte, PwC, EY, KPMG — all publicly distributed)
  • Vendor-published product documentation (SAP, Oracle, Workday, NetSuite, Intacct, FloQast, BlackLine, Anaplan, OneStream, Workiva — public marketing and docs)
  • Gartner, Forrester, IDC public analyst reports (where publicly available)
  • FEI, IMA, and AICPA practitioner publications
  • Academic accounting research published in peer-reviewed journals
  • Public-domain conference proceedings and analyst commentary

5. Author's Independent Practitioner Analysis

Analytical content — including the 17-phase lifecycle model, finance-tiered defect framework (F1–F4), subledger-to-GL design patterns, UAT test case methodology for finance outcomes, the "finance-ready vs. system-ready" distinction, controller sign-off milestone framework, the reference architecture patterns, and the implementation sequence guidance in every playbook — represents the author's independent interpretation and synthesis of public sources and generalized industry practice. Worked journal entries, SOX control wording examples, vendor assessments, and template structures are illustrative — constructed to demonstrate accounting mechanics and governance design. Analysis is offered as general industry reference, not as a prescription for any specific company or project.
