Companies Without Recent 10-K Filings

While compiling the auditor information for S&P 500 companies, it was noted that some companies did not have recent 10-K filings available. As a result, the auditor details for these companies could not be retrieved. The companies in question include Copart (CPRT)GE Vernova (GEV)Smurfit WestRock (SW)Solventum (SOLV), and Supermicro (SMCI)

The Importance of Auditor Choice

The choice of auditor is critical for S&P 500 companies as it impacts investor confidence, regulatory compliance, and overall market perception. Auditors provide an independent assessment of a company’s financial health, ensuring transparency and accuracy in financial reporting.

Extracting Auditor Information from SEC XBRL Filings

In the realm of financial analysis and corporate governance, accessing accurate and up-to-date information is crucial. One effective way to gather such data is by extracting it directly from SEC XBRL filings. In this section, I’ll walk you through the process of how I pulled auditor information for S&P 500 companies using Python.

Why Extract Data from SEC XBRL Filings?

SEC XBRL filings are a treasure trove of financial data, providing detailed insights into a company’s financial health, governance, and compliance. By leveraging these filings, analysts and researchers can obtain precise and reliable information directly from the source.

Python Code to Extract Auditor Details

To extract auditor details from SEC XBRL filings, I used the following Python code. This script utilizes the requests library to fetch the filings, BeautifulSoup to parse the HTML content, and pandas to organize the data into a structured format.

import requests
from bs4 import BeautifulSoup
import pandas as pd
import time

def get_auditor_details(cik, access_number, file_name, debug=False):
    url = f"https://www.sec.gov/Archives/edgar/data/{cik}/{access_number}/{file_name}"
    headers = {
        "User-Agent": "yourname (youremail@email.com)"
    }
    
    try:
        response = requests.get(url, headers=headers)
        response.raise_for_status()  # Check for HTTP errors

        soup = BeautifulSoup(response.content, 'html.parser')
        
        if debug:
            print(f"Fetched URL: {url}")
            print(soup.prettify())

        # Look for the ix:nonnumeric tag with name="dei:AuditorName"
        auditor_name_tag = soup.find('ix:nonnumeric', {'name': 'dei:AuditorName'})
        auditor_location_tag = soup.find('ix:nonnumeric', {'name': 'dei:AuditorLocation'})

        auditor_name = auditor_name_tag.get_text(strip=True) if auditor_name_tag else "Auditor Name not found."
        auditor_location = auditor_location_tag.get_text(strip=True) if auditor_location_tag else "Auditor Location not found."

        # Extract the principal address components
        address_line1 = soup.find('ix:nonnumeric', {'name': 'dei:EntityAddressAddressLine1'})
        city = soup.find('ix:nonnumeric', {'name': 'dei:EntityAddressCityOrTown'})
        state = soup.find('ix:nonnumeric', {'name': 'dei:EntityAddressStateOrProvince'})

        # Construct the full address
        principal_address = ""
        if address_line1:
            principal_address += address_line1.get_text(strip=True) + ", "
        if city:
            principal_address += city.get_text(strip=True) + ", "
        if state:
            principal_address += state.get_text(strip=True)

        # Remove trailing comma and space if necessary
        principal_address = principal_address.rstrip(', ')
        if not principal_address:
            principal_address = "Principal Address not found."

        return auditor_name, auditor_location, principal_address
