ISC CPA Exam: How to Perform Procedures to Identify Subsequent Events That Could Require Disclosure Related to a SOC 1 or SOC 2 Engagement

Introduction

Brief Overview of SOC 1 and SOC 2 Engagements

In this article, we’ll cover how to perform procedures to identify subsequent events that could require disclosure related to a SOC 1 or SOC 2 engagement. SOC 1 and SOC 2 engagements are critical frameworks used by service organizations to demonstrate that their internal controls meet relevant standards. These engagements are performed by CPAs to provide assurance over the design and operational effectiveness of controls.

• SOC 1 Engagements focus on controls related to financial reporting. They are typically used by organizations whose services or systems have a direct impact on their clients’ financial statements. For example, payroll processors, loan servicing companies, and data centers are common candidates for SOC 1 reports. The purpose of a SOC 1 report is to ensure that the service organization’s control environment adequately supports accurate and reliable financial data processing for their clients.
• SOC 2 Engagements, on the other hand, concentrate on controls related to five Trust Service Criteria: security, availability, processing integrity, confidentiality, and privacy. These reports are used by technology companies, cloud service providers, and other IT service organizations to provide assurance to their customers that their data and systems are secure and properly managed. SOC 2 engagements are particularly important for businesses that handle sensitive information or provide critical IT infrastructure.

Importance of Identifying Subsequent Events in SOC Engagements

Subsequent events are events or transactions that occur after the report period but before the issuance of the SOC 1 or SOC 2 report. Identifying and addressing subsequent events is crucial because these events can have a significant impact on the service organization’s control environment and, ultimately, on the assurance provided by the SOC report.

For example, a system breach or a major organizational change after the reporting period could affect the controls under review, raising concerns about their reliability or effectiveness. If these events are not identified and disclosed, it could lead to inaccurate conclusions about the control environment, potentially misleading the report users who rely on SOC reports for decision-making. Therefore, identifying subsequent events helps ensure that stakeholders receive accurate and timely information about the service organization’s control environment.

Purpose of the Article

This article is designed to guide CPAs through the process of identifying subsequent events in SOC 1 and SOC 2 engagements. It provides detailed procedures to recognize, evaluate, and disclose these events, ensuring compliance with auditing standards and enhancing the accuracy of the reports. By understanding how to handle subsequent events effectively, CPAs can help service organizations maintain transparency and build trust with their clients and stakeholders.

Understanding Subsequent Events

Definition of Subsequent Events

Subsequent events refer to events or transactions that occur after the end of the reporting period but before the issuance of a financial report or audit opinion. These events can have significant implications for the accuracy and completeness of the report, especially when they affect the control environment under evaluation in SOC 1 or SOC 2 engagements.

Definition per Auditing Standards (e.g., PCAOB or AICPA Standards)

According to the PCAOB (Public Company Accounting Oversight Board) and AICPA (American Institute of Certified Public Accountants) standards, subsequent events are classified into two main categories:

1. Recognized Subsequent Events: These are events that provide additional evidence about conditions that existed at the end of the reporting period. They are typically recorded in the financial statements because they relate to conditions that were already present but only became fully apparent after the reporting period. An example would be the settlement of a lawsuit that was initiated before the reporting period but was resolved afterward, clarifying the financial obligation.
2. Non-Recognized Subsequent Events: These events occur after the reporting period and do not provide evidence of conditions that existed during the reporting period. Instead, they reflect new events or changes that occurred after the period ended. While these events are not included in the financial statements themselves, they may require disclosure if they are material to the users of the report. An example might be a significant acquisition or sale of assets after the reporting period that could influence users’ decisions.

Impact of Subsequent Events on Financial Reporting

Subsequent events play a critical role in ensuring the integrity of the information provided in SOC 1 and SOC 2 reports. Proper identification and disclosure of these events help maintain the relevance and reliability of the report for its users, whether they are clients relying on the organization’s financial reporting controls (SOC 1) or customers concerned with operational security and compliance (SOC 2).

How They Affect Financial Statements or Reports Under SOC 1

In a SOC 1 engagement, subsequent events are especially important because they can directly impact the financial reporting process. For instance, if a material control failure is discovered after the reporting period, this failure could indicate that the controls in place during the reporting period were inadequate, potentially affecting the accuracy of financial reporting.

Recognized subsequent events in a SOC 1 engagement might include the discovery of errors or control failures related to financial reporting processes that existed during the reporting period. Such events require adjustments to ensure the financial data’s accuracy, as these failures could result in misstatements or discrepancies.

Non-recognized subsequent events in SOC 1 engagements could include significant organizational changes—such as a merger or acquisition—that do not affect past financial reporting but may influence the overall control environment going forward. These events typically require disclosure to inform users of the SOC 1 report about significant changes that could affect their reliance on the service organization’s controls.

How They Affect Compliance and Operational Controls Under SOC 2

In SOC 2 engagements, subsequent events affect the service organization’s operational controls, which are tied to the five Trust Service Criteria: security, availability, processing integrity, confidentiality, and privacy. If a subsequent event compromises one of these criteria, it can significantly alter the report’s conclusions and affect how users view the organization’s ability to meet its obligations.

For example, a security breach discovered after the reporting period might indicate that the controls in place during the reporting period were insufficient. This would require disclosure in the SOC 2 report, as it impacts the trustworthiness of the organization’s operations and could affect customer confidence.

Similarly, non-recognized events such as the implementation of new security protocols or changes to privacy policies may not affect the previous reporting period but should still be disclosed if they materially affect the organization’s control environment. Such disclosures ensure that stakeholders have the full picture of the organization’s ongoing ability to meet its compliance obligations, even if the events occurred after the original reporting period.

Understanding these distinctions is critical for CPAs engaged in SOC 1 and SOC 2 reporting, as failure to properly identify and disclose subsequent events could lead to misleading reports and undermine the credibility of the organization.

Overview of SOC 1 and SOC 2 Engagements

SOC 1 Engagements

Purpose: Addressing Controls Relevant to Financial Reporting

SOC 1 (System and Organization Controls 1) engagements are designed to evaluate the internal controls of service organizations that are relevant to their clients’ financial reporting. The primary objective of a SOC 1 engagement is to provide assurance that a service organization has appropriate controls in place to support its clients in achieving accurate and reliable financial statements. These engagements focus on controls that could impact financial processes such as transaction processing, financial data integrity, and system reliability.

In a SOC 1 report, CPAs evaluate both the design and operational effectiveness of internal controls, offering assurance to the service organization’s clients (often referred to as “user entities”) that their financial information is being handled properly. The SOC 1 report is particularly important for organizations that outsource essential financial processes, as it provides them with a detailed examination of the service provider’s control environment, helping to reduce risks of material misstatements in their own financial reports.

Types of Clients Typically Involved

SOC 1 engagements are commonly performed for service organizations that play a direct role in processing or managing critical financial information for their clients. Some of the most typical clients include:

• Payroll Processors: Organizations that handle payroll functions on behalf of their clients are often subject to SOC 1 engagements. Since payroll processing affects employee wages, tax withholdings, and benefits, these companies must demonstrate that their systems and processes support accurate and compliant financial reporting.
• Data Centers: Data centers that provide hosting or managed services for financial applications and databases may also be the focus of SOC 1 engagements. Since these centers handle the storage and transmission of critical financial data, the security and reliability of their operations are vital to ensuring the accuracy of client financial reporting.
• Loan Servicing Companies: Companies that service loans, such as mortgage servicers or student loan administrators, are often required to undergo SOC 1 engagements. Their role in processing payments, interest calculations, and reporting balances directly impacts the financial statements of their clients.
• Third-Party Billing and Accounts Receivable Providers: Organizations that handle billing, invoicing, and accounts receivable management on behalf of their clients are frequently subject to SOC 1 engagements. These processes are central to a client’s revenue recognition and cash flow reporting, making the accuracy and timeliness of these services critical.

SOC 1 engagements are an essential part of the financial reporting ecosystem for organizations that outsource key financial functions. By obtaining a SOC 1 report, user entities can gain confidence in the service provider’s ability to maintain adequate internal controls and reduce risks related to financial reporting errors or fraud.

SOC 2 Engagements

Purpose: Addressing Controls Relevant to Security, Availability, Processing Integrity, Confidentiality, and Privacy

SOC 2 (System and Organization Controls 2) engagements are designed to assess the internal controls of service organizations related to systems and data, particularly in areas that affect the Trust Service Criteria. These criteria include security, availability, processing integrity, confidentiality, and privacy, all of which are critical for organizations handling sensitive data and operating in industries where information security is paramount.

The primary purpose of a SOC 2 report is to provide assurance to customers and stakeholders that the service organization’s systems are protected against unauthorized access (security), remain available for operation as expected (availability), process data accurately (processing integrity), ensure confidentiality of data (confidentiality), and properly handle personal information in accordance with privacy regulations (privacy). Unlike SOC 1, which focuses on financial reporting, SOC 2 engagements center on operational and compliance controls, making them particularly relevant for organizations providing technology and information services.

Types of Organizations Using SOC 2 Reports

SOC 2 reports are widely used by organizations that offer services involving the storage, processing, or transmission of customer data. These organizations must demonstrate to their customers that they have appropriate controls in place to safeguard sensitive information and ensure the continuity and reliability of their services. Typical organizations that use SOC 2 reports include:

• IT Service Providers: Organizations that provide managed IT services, including infrastructure management, network administration, and IT support, frequently undergo SOC 2 engagements. Since these service providers often have access to client data and systems, their ability to maintain security and data integrity is critical.
• Cloud Service Providers: Cloud computing companies that offer infrastructure, platform, or software services (e.g., IaaS, PaaS, SaaS) are key users of SOC 2 reports. Cloud providers manage large volumes of data and must demonstrate that their systems meet the required standards for security, availability, and privacy to ensure customer trust.
• Data Centers: Data centers that host and manage critical IT infrastructure for clients are responsible for ensuring the continuous availability of systems and the protection of data. SOC 2 reports help these organizations prove their commitment to maintaining secure, reliable, and compliant operations.
• SaaS Providers: Software-as-a-Service companies, which deliver applications over the internet, must ensure that their systems maintain high levels of security and data integrity. A SOC 2 report demonstrates their controls for processing customer transactions and handling confidential data within their platform.
• Healthcare Technology Companies: Organizations in the healthcare industry, particularly those managing electronic medical records (EMR) or health information exchanges, are required to maintain strict confidentiality and privacy controls. SOC 2 reports allow these companies to demonstrate compliance with regulatory frameworks like HIPAA, ensuring that patient data is handled securely and confidentially.
• Financial Technology (FinTech) Companies: FinTech companies often process financial transactions and manage sensitive personal information. Given the high standards for data security and privacy in this industry, SOC 2 reports are crucial for building client confidence and complying with regulatory requirements.

SOC 2 reports are essential for any organization that handles sensitive data or relies on technology infrastructure to deliver services to its customers. They provide transparency into the service provider’s controls related to security, availability, processing integrity, confidentiality, and privacy, offering assurance that the organization can safeguard customer data and meet operational demands effectively.

Identifying Subsequent Events in a SOC 1 or SOC 2 Engagement

Timing and Period of Consideration

Subsequent events in SOC 1 or SOC 2 engagements refer to events that occur after the reporting period end but before the report is issued. These events must be carefully evaluated to determine if they affect the controls or processes reviewed during the engagement. The period of consideration typically extends from the date the control period ends (i.e., the last day of the reporting period) to the report issuance date. During this time, any relevant changes or incidents that could influence the control environment must be identified and addressed.

For SOC 1 and SOC 2 engagements, CPAs are required to assess subsequent events that could either:

• Alter the evaluation of the control environment for the reporting period, requiring modifications to the conclusions or findings in the report.
• Introduce new risks or significant changes that, while not impacting the controls during the reporting period, should still be disclosed to the report’s users for transparency and completeness.

Recognizing and disclosing such events is essential to maintain the reliability and relevance of SOC 1 and SOC 2 reports, as stakeholders rely on these reports for critical decision-making.

Common Types of Subsequent Events in SOC 1 and SOC 2 Engagements

Changes in Control Processes Affecting Financial Reporting (SOC 1)

In a SOC 1 engagement, subsequent events that affect the internal controls over financial reporting are of paramount concern. Common events include:

• Failures or weaknesses in financial reporting controls: If an organization experiences a significant control failure after the end of the reporting period but before the report issuance, it may suggest that similar weaknesses existed during the period under review. For example, a breakdown in transaction processing controls that leads to financial inaccuracies could indicate that the controls were not operating effectively during the reporting period.
• Modifications to financial systems or processes: Changes in key financial reporting systems, such as upgrades to an ERP system or major adjustments to accounting software, may introduce new risks or control failures. These changes, if occurring after the reporting period, should be evaluated to determine their impact on the reliability of prior controls.
• Discovery of material financial misstatements: The identification of financial misstatements during a review process that postdates the reporting period could suggest that controls over financial reporting were inadequate. This type of event may necessitate changes to the SOC 1 report or require detailed disclosure.

Changes in Security, Availability, or Privacy Controls (SOC 2)

For SOC 2 engagements, subsequent events often involve the organization’s operational and compliance controls related to the Trust Service Criteria. Common types of subsequent events that could impact SOC 2 engagements include:

• Security breaches: A security breach or cyberattack discovered after the reporting period could signal that the organization’s security controls were insufficient. Even if the breach occurred after the control period ended, it could reveal vulnerabilities that existed during the period and may necessitate revisions or disclosures.
• Outages affecting availability: Service disruptions or significant outages that occur after the reporting period, but before report issuance, may reflect deficiencies in availability controls. If the organization’s systems failed to maintain continuous operation, it might raise concerns about whether those controls were adequate during the reporting period.
• Changes to data privacy protocols: Any adjustments to the organization’s handling of sensitive customer data (e.g., implementing new privacy policies or encountering data handling issues) could materially impact the confidentiality and privacy controls reviewed during a SOC 2 engagement. Even if these changes occurred after the reporting period, they might require disclosure to ensure users are aware of potential risks.

Business Acquisitions, Legal Claims, or Changes in Management That Could Impact Control Environments

Another category of subsequent events that may affect both SOC 1 and SOC 2 engagements involves major organizational changes. These events may not directly relate to the control processes but can still impact the control environment and thus require disclosure:

• Business acquisitions or mergers: An acquisition or merger occurring after the reporting period could introduce new risks or require substantial changes to existing controls. For instance, new systems, processes, or management structures could affect the organization’s ability to maintain effective control environments.
• Legal claims or regulatory investigations: New or emerging legal claims or regulatory issues that arise after the control period might indicate potential compliance risks or previously unrecognized vulnerabilities. These events may necessitate disclosure to ensure users are aware of the potential impact on the organization’s operations.
• Changes in key management personnel: A significant change in leadership or key personnel responsible for maintaining the control environment could signal instability or risks within the organization. If these changes occur after the reporting period, they should be disclosed to provide transparency about the organization’s capacity to maintain effective control processes going forward.

Identifying these types of subsequent events is essential to maintaining the accuracy and completeness of SOC 1 and SOC 2 reports, ensuring stakeholders receive a full picture of the service organization’s control environment.

Procedures to Identify Subsequent Events

Inquiry with Management

One of the most effective procedures for identifying subsequent events is direct inquiry with management. This step involves engaging relevant stakeholders within the organization to gather information about events or transactions that have occurred since the end of the reporting period. By speaking with individuals who have firsthand knowledge of the organization’s operations, auditors can gain valuable insights into potential subsequent events that may require disclosure.

Importance of Discussing Subsequent Events with Relevant Stakeholders

To perform thorough inquiries, auditors should meet with key personnel such as IT directors, CFOs, internal control teams, and legal counsel. Each of these stakeholders plays a critical role in the organization’s control environment, and their insights can help identify material events that might otherwise be overlooked.

• IT Directors can provide information about any system outages, data breaches, or changes to IT infrastructure that could impact controls related to security or availability (especially important for SOC 2).
• CFOs and accounting teams may have knowledge of financial transactions, such as loans, settlements, or other financial matters that could affect controls relevant to financial reporting (crucial for SOC 1).
• Internal control teams are familiar with the day-to-day functioning of control processes and can highlight any weaknesses, failures, or changes in the operation of those controls.
• Legal counsel is vital for identifying potential legal claims, regulatory matters, or significant contracts that might require disclosure.

Inquiring with management helps ensure that auditors have access to up-to-date information and can evaluate whether any new events warrant recognition or disclosure in the SOC 1 or SOC 2 report.

Review of Documentation

Another critical procedure for identifying subsequent events is the review of internal documentation. This involves examining key organizational documents that may contain references to significant events or changes that have occurred since the reporting period ended.

Reviewing Key Internal Documents

To identify potential subsequent events, auditors should review the following types of documents:

• Board Meeting Minutes: Board minutes can provide valuable information about decisions made by senior leadership, such as major strategic changes, mergers, or acquisitions. These events could have a direct impact on the control environment.
• Legal Letters: Reviewing correspondence between the organization and its legal counsel is essential for identifying any new legal claims, regulatory matters, or pending litigation. Such issues may necessitate disclosure, especially if they affect the organization’s compliance obligations or financial standing.
• Incident Reports: For SOC 2 engagements, reviewing incident reports is crucial to identifying breaches in security, service outages, or other operational disruptions. These reports often reveal problems that may not have been fully addressed during the control period but could still affect the validity of the control environment.

By thoroughly reviewing these documents, auditors can uncover subsequent events that may not be immediately apparent but still require disclosure to maintain the accuracy of the report.

Analytical Procedures

Analytical procedures can also be useful for identifying subsequent events, particularly by highlighting unusual trends or changes in key metrics that suggest a material event has occurred.

Identifying Trends or Significant Changes in Metrics

When performing analytical procedures, auditors compare current financial or operational data to historical data or forecasts to identify unusual fluctuations. For example:

• Revenue or expense trends that deviate significantly from expectations may indicate that a financial event, such as a large contract or settlement, has occurred after the reporting period.
• Service uptime metrics in SOC 2 engagements can reveal periods of downtime or service disruption that may suggest control weaknesses related to availability.
• Changes in headcount or personnel costs could indicate significant organizational changes, such as layoffs or restructurings, which may have an impact on internal control operations.

By using analytical procedures to identify unexpected variances, auditors can investigate further to determine whether a subsequent event has occurred that requires disclosure.

Subsequent Testing of Controls

Lastly, auditors may need to conduct subsequent testing of controls to verify that controls have continued to operate effectively after the end of the reporting period.

Performing Testing on Controls Related to SOC 1 or SOC 2 for the Subsequent Period

In some cases, auditors will need to test key controls to ensure that they remain effective during the period between the end of the reporting period and the issuance of the report. This is particularly important if a potential subsequent event has been identified that could impact the operation of these controls.

For SOC 1 engagements, subsequent testing might include:

• Reviewing financial transaction processing to verify that controls over financial reporting, such as reconciliations or approval processes, are still operating as intended.

For SOC 2 engagements, subsequent testing might include:

• Reviewing IT security protocols to confirm that access controls, firewall protections, or other key security measures continue to function effectively.
• Testing system availability controls to ensure that measures designed to maintain continuous system uptime have not been compromised since the end of the reporting period.

By performing additional tests on relevant controls, auditors can assess whether any events or changes since the reporting period have affected the effectiveness of the control environment, thereby ensuring that the SOC report remains accurate and reliable.

These procedures—management inquiry, document review, analytical review, and subsequent control testing—are essential for identifying and disclosing subsequent events that could impact SOC 1 or SOC 2 reports.

Evaluating the Impact of Subsequent Events on SOC Reports

For SOC 1 Reports

In SOC 1 engagements, the focus is on controls related to financial reporting. When a subsequent event occurs, auditors must determine whether it necessitates an adjustment to the control environment or reporting. This evaluation involves assessing how the event impacts the accuracy or reliability of the financial controls under review.

• Adjustments to the Control Environment: If the subsequent event reveals a deficiency in the internal controls over financial reporting that existed during the reporting period, it may indicate that those controls were not functioning as expected. For example, if a financial misstatement is discovered after the period ends but is related to a control failure during the period, the control environment may need to be reevaluated, and the SOC 1 report might need to be revised to reflect the deficiency.
• Adjustments to Reporting: In some cases, the event may not directly affect the control environment but may still require disclosure or adjustment in the report. For instance, if a material change in financial processes occurred after the reporting period, this should be disclosed to provide transparency to users of the SOC 1 report. Auditors must evaluate whether the event compromises the reliability of the controls or introduces new risks that must be communicated.

For SOC 2 Reports

In SOC 2 engagements, auditors focus on the Trust Service Criteria, which include security, availability, processing integrity, confidentiality, and privacy. The occurrence of a subsequent event necessitates evaluating whether it affects any of these criteria.

• Security and Confidentiality: If a subsequent event involves a data breach or unauthorized access, it directly impacts the security and confidentiality criteria. Auditors need to assess whether the breach was the result of a control failure that existed during the reporting period. Even if the breach occurred after the reporting period, it may still necessitate disclosure if it raises concerns about the adequacy of the organization’s security controls during the evaluated period.
• Availability: For organizations that rely on continuous system uptime, a significant system outage or downtime could compromise the availability criteria. Subsequent events related to outages should be reviewed to determine if they indicate weaknesses in availability controls that existed during the reporting period.
• Processing Integrity and Privacy: Changes in how the organization processes data or handles privacy issues, such as a violation of privacy regulations or errors in data processing, can also trigger the need for adjustments to the SOC 2 report. Auditors must evaluate whether the controls reviewed in the engagement are still valid in light of the event.

Guidance on Assessing Materiality

Assessing the materiality of a subsequent event is crucial in determining whether it requires disclosure. A subsequent event is considered material if it is likely to influence the decisions of users of the SOC report, such as clients or other stakeholders.

• Materiality in SOC 1: In the context of SOC 1, materiality is often tied to the financial impact of the event. For example, if the event could lead to a material misstatement in the client’s financial reports, it is considered significant enough to require adjustment or disclosure.
• Materiality in SOC 2: For SOC 2 engagements, materiality is often determined based on how the event affects the Trust Service Criteria. A material event could be one that compromises the integrity, security, or availability of systems in a way that significantly impacts users’ trust in the service organization. The magnitude of the impact on security, privacy, or other operational aspects guides the assessment of whether the event must be disclosed.

When assessing materiality, auditors must consider both quantitative and qualitative factors, including the size of the event’s financial impact and its broader implications for the organization’s control environment.

Communication with Stakeholders

Effective communication with stakeholders is essential when evaluating subsequent events. Auditors must discuss the implications of the event and the decision to disclose with management and other relevant parties to ensure that all perspectives are considered and that the final decision aligns with regulatory and reporting standards.

• Internal Discussions with Management: The first step is to meet with the service organization’s management to discuss the nature of the event, its potential impact on the control environment, and whether it meets the threshold for disclosure. These discussions should also explore any actions the organization has taken to address the event, such as mitigating risks or improving controls.
• External Communication with Clients or User Entities: If the subsequent event is deemed material, auditors may also need to communicate with clients or user entities to inform them of the event’s implications. This is particularly important in SOC 1 engagements, where financial reporting accuracy is critical for clients’ decision-making. For SOC 2, clients may need to be reassured that controls over security or privacy are being addressed and that any risks arising from the event are being managed.
• Legal and Regulatory Considerations: Depending on the nature of the event, auditors may also need to involve legal counsel to ensure that disclosures are made in compliance with contractual obligations and regulatory requirements. This is especially relevant in cases where privacy laws, such as GDPR or HIPAA, are involved, and data breaches or security incidents must be reported to regulatory bodies.

By maintaining open lines of communication with all stakeholders, auditors can ensure that the impact of subsequent events is properly evaluated and that any necessary disclosures are made in a timely and transparent manner.

Disclosure Requirements for SOC 1 and SOC 2 Reports

When and How to Disclose

The disclosure of subsequent events in SOC 1 and SOC 2 reports is an important part of maintaining transparency and ensuring the accuracy of the reports. The decision to disclose depends on whether the event is recognized or non-recognized, and the specific guidance provided by auditing standards must be followed to determine the proper treatment.

Reporting Standards for Recognized and Non-Recognized Events

• Recognized Subsequent Events: These events provide additional evidence about conditions that existed at the end of the reporting period. For example, if a control failure that occurred during the period only comes to light after the period has ended, it would be considered a recognized subsequent event. In this case, the event should be reflected in the SOC 1 or SOC 2 report as it affects the conclusions about the control environment during the reporting period.
• Non-Recognized Subsequent Events: These events occur after the end of the reporting period and are unrelated to conditions that existed at that time. However, they may still be important to users of the report if they are material or could impact the future control environment. While these events do not require adjustments to the reported controls, they may require disclosure if they are likely to influence the decisions of users. For instance, a security breach occurring after the reporting period might be disclosed in a SOC 2 report to provide transparency about potential risks going forward.

Formatting and Placement of Disclosures in SOC 1 and SOC 2 Reports

When subsequent events require disclosure, it is critical to ensure that the information is presented clearly and is easily accessible to the users of the report. Auditors must follow established formatting and placement guidelines:

• In SOC 1 Reports: Disclosures related to subsequent events typically appear in a separate section of the report, often titled “Subsequent Events” or “Other Matters.” In this section, auditors should describe the event, explain its impact on the control environment, and outline any actions taken by the service organization to address the issue. The placement of this section near the end of the report ensures that users are aware of these events without interrupting the flow of the main control findings.
• In SOC 2 Reports: Similarly, SOC 2 reports include disclosures about subsequent events in a dedicated section, ensuring transparency regarding changes in the control environment or the occurrence of incidents such as security breaches or changes in privacy policies. The disclosure should explain the nature of the event, its potential impact on the relevant Trust Service Criteria (e.g., security or confidentiality), and any remediation efforts by the organization.

Regardless of the report type, disclosures must be written in clear, concise language, focusing on the implications of the subsequent event for the users of the report.

Legal and Compliance Considerations

Ensuring that disclosures comply with relevant standards and contractual obligations is a crucial part of the reporting process. Failure to disclose material subsequent events properly could result in legal repercussions or breach of client agreements, particularly in highly regulated industries.

Ensuring Compliance with Relevant Standards and Contractual Obligations Related to Subsequent Event Disclosures

• Compliance with Auditing Standards: Auditors must adhere to the disclosure requirements outlined by relevant auditing standards, such as those issued by the AICPA or PCAOB. These standards provide detailed guidance on when and how subsequent events should be disclosed, ensuring that the reports remain compliant with professional best practices.
• Regulatory Requirements: In some industries, particularly those dealing with sensitive information such as healthcare, finance, or technology, specific regulatory requirements may dictate how subsequent events should be disclosed. For example, if a security breach affects personally identifiable information (PII), the auditor may need to ensure that the disclosure aligns with data protection regulations such as HIPAA (in the U.S.) or GDPR (in the EU). Failure to comply with these regulations can result in significant penalties or reputational damage.
• Contractual Obligations: Service organizations often have contracts with clients that include specific clauses about the disclosure of incidents or subsequent events. Auditors must review these contracts to ensure that their disclosure practices meet any contractual obligations. For instance, a service agreement may require immediate notification to clients if a security breach or control failure is discovered after the reporting period.
• Engagement Letters: The terms outlined in the engagement letter between the auditor and the service organization may also include specific requirements for handling subsequent events. This document often outlines the auditor’s responsibilities regarding disclosures and should be referenced to ensure compliance.

By following legal and compliance guidelines and carefully adhering to the reporting standards, auditors can help service organizations maintain their credibility and ensure that all material subsequent events are disclosed in a manner that meets professional, regulatory, and contractual standards.

Example Scenario

Practical Example of Identifying a Subsequent Event in a SOC 1 or SOC 2 Engagement

Let’s consider a SOC 2 engagement for a cloud service provider, CloudSecure, which provides data storage and processing services to its clients. The SOC 2 report covers the control period from January 1, 2023, to December 31, 2023, and focuses on the Trust Service Criteria of security and availability. The engagement was completed, and the report is due to be issued on March 15, 2024.

Identifying the Subsequent Event

In February 2024, CloudSecure experiences a significant security breach. An external attacker exploited a vulnerability in the company’s firewall, gaining unauthorized access to sensitive client data. CloudSecure’s IT team promptly identified the breach and initiated corrective actions, including patching the vulnerability, notifying affected clients, and improving the monitoring of network traffic to prevent future breaches.

This breach occurred after the end of the reporting period but before the SOC 2 report was issued.

Determining Whether the Event Requires Disclosure

The auditing team must now evaluate whether this subsequent event requires disclosure in the SOC 2 report. Several factors will guide the decision-making process:

1. Assessing the Timing and Nature of the Event: Since the breach occurred after the reporting period (i.e., January 1 to December 31, 2023), it is considered a non-recognized subsequent event. This means that it doesn’t affect the control environment during the reporting period itself, but it is a significant new event that occurred after the control period ended.
2. Evaluating the Impact on the Trust Service Criteria: The security breach directly impacts the security Trust Service Criteria because it involved unauthorized access to sensitive client data. Even though the breach occurred in 2024, users of the SOC 2 report will likely want to know about this event to assess CloudSecure’s ability to protect their data in the future.
3. Assessing Materiality: The security breach is a material event because it compromises the security of client data and could lead to reputational and financial harm for both CloudSecure and its clients. Given the significance of the breach, it is essential to disclose the event to provide transparency to report users, especially since data protection is one of the core areas covered by the SOC 2 engagement.

Disclosure Decision

After discussions with CloudSecure’s management and legal counsel, and based on auditing standards, the audit team determines that the security breach does require disclosure. Although it is a non-recognized subsequent event, the breach is material because it affects the Trust Service Criteria of security, which is critical to the SOC 2 report.

Disclosure in the SOC 2 Report

The audit team includes a disclosure about the breach in a dedicated “Subsequent Events” section near the end of the SOC 2 report. The disclosure includes:

• A brief description of the event: An unauthorized external party exploited a vulnerability in CloudSecure’s firewall in February 2024, gaining access to sensitive client data.
• The actions taken by CloudSecure: The company patched the vulnerability, notified affected clients, and implemented additional monitoring controls to prevent future incidents.
• A statement on the impact: While the breach occurred after the control period, the security controls in place during the reporting period were not affected. However, the breach highlights ongoing risks to CloudSecure’s security environment, which the company is actively addressing.

By including this disclosure, CloudSecure ensures transparency about the security breach, and users of the SOC 2 report have the information needed to assess the organization’s security posture moving forward.

This example highlights the importance of identifying and evaluating subsequent events in SOC engagements. Even though the event in this scenario occurred after the control period, its material impact on the security Trust Service Criteria made it necessary to disclose the event. Auditors must carefully assess the timing, nature, and materiality of subsequent events to determine whether they require disclosure, ensuring that users of the SOC report have complete and accurate information.

Conclusion

Recap of Key Points About Identifying and Addressing Subsequent Events

Identifying and addressing subsequent events in SOC 1 and SOC 2 engagements is a critical part of ensuring that reports are accurate, transparent, and reliable. Key points covered in this article include:

• Timing and Nature of Subsequent Events: These events occur after the reporting period but before the issuance of the SOC report. They can be recognized (relating to conditions that existed during the reporting period) or non-recognized (new events that occurred after the reporting period).
• Procedures for Identifying Events: Auditors must perform inquiries with management, review internal documentation, apply analytical procedures, and perform subsequent control testing to identify events that could impact the control environment.
• Evaluating Materiality: Auditors must assess the materiality of subsequent events to determine whether they require disclosure. Events that significantly affect the control environment or the users’ ability to rely on the SOC report must be disclosed.
• Disclosure in SOC Reports: For material subsequent events, auditors should include clear and transparent disclosures, ensuring users understand the event’s impact on the control environment and any actions taken by the organization.

Final Thoughts on the Importance of Monitoring for Subsequent Events Even After Engagement Completion

Monitoring for subsequent events is crucial even after the initial completion of the engagement. Changes in controls, security breaches, operational disruptions, or legal matters can arise at any time before the report is issued. Failing to identify and address these events can lead to incomplete or misleading SOC reports, potentially harming stakeholders’ decision-making processes and the service organization’s reputation.

Auditors and service organizations must remain vigilant during the period between the end of the control evaluation and the report’s issuance. The ability to accurately identify and disclose subsequent events ensures that the SOC report remains a trusted document for all its users.

Encouragement for Thorough Documentation and Communication Throughout the Process

To effectively manage subsequent events, thorough documentation and clear communication are essential. Auditors should:

• Document every inquiry, review, and test performed: This ensures a complete audit trail and helps validate the conclusions reached regarding subsequent events.
• Maintain open lines of communication with management and other stakeholders: This facilitates the timely identification of events and ensures that everyone involved understands the potential impact of these events on the SOC report.

By taking a proactive approach to identifying subsequent events and maintaining a strong documentation process, auditors can help ensure the integrity of the SOC 1 and SOC 2 reports, protecting both the service organization and its clients.
