Who this service is for

This service is built for companies based in Mexico, Central America, Colombia and across Latin America that are going public in the United States or already file with the SEC, and that want an auditor whose team works in Spanish as naturally as in English. Typical situations:

  • A family-owned or founder-led group preparing its first registration statement.
  • A company combining with a U.S. shell or SPAC (see reverse merger audits).
  • A foreign private issuer already filing Form 20-F that wants a closer working relationship with its auditor.
  • A U.S.-listed holding company whose operations and accounting team are in Latin America.

Choosing the route to the U.S. market

The filing route depends mainly on where the listed entity is incorporated and on whether it qualifies as a foreign private issuer (FPI) under Exchange Act Rule 3b-4 and Securities Act Rule 405. Your securities counsel makes that determination; we plan the audit around it.

Listed entityRegistrationPeriodic reportsFinancial statements
Non-U.S. company that qualifies as an FPIForm F-1Form 20-F and Form 6-KIFRS as issued by the IASB, or U.S. GAAP

U.S.-incorporated holding company with Latin American operationsForm S-1Forms 10-K, 10-Q and 8-KU.S. GAAP

A U.S. holding company is not a foreign issuer, so FPI accommodations do not apply to it, wherever its operations are. Regulation A+ is narrower than many founders expect: Rule 251(b)(1) limits it to entities organized in the United States or Canada and with their principal place of business there. A company organized in Latin America cannot use it directly, and a new U.S. or Canadian parent qualifies only if the principal-place-of-business test is also met.

What is included

PCAOB audits for the registration statement and annual reports

We audit the financial statements required in your F-1 or S-1 and, after listing, in your Form 20-F or Form 10-K, under PCAOB standards, and issue the auditor's consents the registration statement needs. For IPO timing and staleness rules, see our IPO and S-1 audit page.

Local GAAP to IFRS or U.S. GAAP

Most Latin American companies keep their books under local standards or a local version of IFRS (NIIF). An SEC filing needs IFRS as issued by the IASB, stated without reservation, or U.S. GAAP. Before fieldwork we help you understand what the audit will require: first-time adoption under IFRS 1, differences between local NIIF and IASB IFRS, tax-driven accounting, related-party balances, functional currency, and IAS 29 where a subsidiary operates in a hyperinflationary economy.

Note: Independence rules prohibit an auditor from preparing the financial statements it audits. Your finance team or an independent adviser prepares the conversion; we audit it.

Spanish source documents

Contracts, deeds, board minutes, tax filings and bank confirmations can stay in Spanish; our engagement team reads them directly. That avoids paying to translate evidence that only the auditor needs to read. The filing and the audit report are in English, as Regulation S-T Rule 306 requires.

Coordination with local statutory auditors

Your statutory audit under local law usually continues. When another firm performs audit work that we use, we direct and supervise it under PCAOB standards and disclose it on Form AP. A firm that performs the majority of the audit work on a subsidiary representing 20% or more of consolidated assets or revenues, or 20% or more of the engagement hours or fees, plays a "substantial role" under PCAOB Rule 1001(p)(ii) and must itself be PCAOB-registered.

Working in your time zone

Guatemala City is on UTC-6 year-round. Your finance team, U.S. counsel and our engagement team can meet during a shared working day.

Typical timeline for a first engagement

Illustrative only. The number of years audited, the conversion workload and the number of countries change it significantly; your timeline is confirmed in your written proposal.

  1. Weeks 1–2Scoping and acceptance

    Call in Spanish or English with management and counsel, FPI and structure analysis, and independence checks under SEC Rule 2-01 and PCAOB Rule 3520.

  2. Weeks 3–6Framework and planning

    Review of management's conversion plan, opening balances, group structure and component auditors.

  3. Weeks 7–14Fieldwork

    Audit of each required year, testing of the conversion adjustments and review of component work.

  4. Weeks 15–18Completion and report

    Engagement quality review, audit report and consent for the registration statement.

  5. After filingSEC comments

    Support on staff comments that concern the audited financial statements, and Form AP within the PCAOB deadline.

Documents to prepare

  • Articles of incorporation, bylaws and a group structure chart for every entity (Spanish is fine).
  • Trial balances and general ledgers for each year to be audited.
  • Local statutory financial statements and audit reports.
  • Management's IFRS or U.S. GAAP conversion workbook and accounting policy memos.
  • Shareholder register and cap table, to support the FPI analysis.
  • Board and shareholder minutes, material contracts, loan agreements and related-party agreements.
  • Tax returns and correspondence with local tax authorities.
  • Contact details of statutory auditors in each country.
  • Draft registration statement or offering timetable from counsel or the underwriter.

What drives the fee

We agree a fixed fee in writing before fieldwork. The main drivers are:

  • Number of fiscal years to audit and whether they have been audited before.
  • Scope of the IFRS or U.S. GAAP conversion.
  • Number of countries, entities and component auditors.
  • Quality and accessibility of accounting records.
  • Currency and hyperinflation work.
  • Registration statement amendments and SEC comment rounds.

FAQ

Frequently asked questions

Can a company incorporated in Mexico or Colombia use Regulation A+?

Generally no. Rule 251(b)(1) limits Regulation A to entities organized under U.S. or Canadian law with their principal place of business in the United States or Canada. A company organized in Latin America does not qualify. Some groups form a U.S. or Canadian parent, but the principal-place-of-business test also has to be met, and that is a question for securities counsel.

Do we have to convert our financial statements to U.S. GAAP?

Not necessarily. A foreign private issuer may present IFRS as issued by the IASB without a U.S. GAAP reconciliation. U.S. GAAP is required if the registrant is a domestic filer, which includes a U.S.-incorporated holding company and a foreign company that fails the foreign private issuer test. The choice of legal structure therefore drives the accounting framework.

Can SESGLO prepare our IFRS conversion as well as audit it?

No. SEC and PCAOB independence rules prohibit the auditor from preparing the financial statements it audits or keeping the underlying records. Your finance team or an independent adviser prepares the conversion. We can explain what the audit will require, agree the timetable, and audit the result, but the accounting judgments and entries must be management's.

Our local statutory auditor already audits the company. Why do we need another firm?

SEC filings require an audit under PCAOB standards by a PCAOB-registered firm. Many local firms are not registered or do not perform PCAOB audits. The statutory audit under local rules usually continues in parallel, and we coordinate with that firm so that its work and ours do not duplicate requests to your team.

Can we communicate with the audit team entirely in Spanish?

Yes. Meetings, requests, working sessions and audit committee discussions can be held in Spanish. Your source documents can stay in Spanish. Anything that goes to the SEC or the PCAOB, including the audit report, is prepared in English, and we help your team review the English versions for consistency with the Spanish records.

How long does a first audit for a U.S. listing usually take?

It depends on the number of years to be audited, the state of the records, whether an IFRS or U.S. GAAP conversion is needed and how many countries are involved. An illustrative first engagement runs several months from acceptance to report. We give you a week-by-week timeline in the written proposal rather than a generic estimate.
