BENSON – Independent financial and accounting firm Moss Adams conducted its annual comprehensive audit of Arizona Electric Power Cooperative (AEPCO) and Sierra Southwest Cooperative Services (Sierra), and found no issues with their financial reporting for 2019. In the financial industry, that’s known as a “clean audit.”

Together, AEPCO and Sierra form Arizona G&T Cooperatives (AzGT). AzGT employees performed a great deal of behind-the-scenes work throughout 2019 that made the clean audit possible.

“The audit is always in the back our minds, and we’re always preparing for it,” said Arnold Murphy, AzGT manager of accounting and tax, adding that the process benefits AzGT by offering a chance for detailed self-examination.

For example, solar projects receive tax incentives to lower their costs. “We’ve been working to get a property-tax reduction from Cochise County because it incorrectly categorized our Apache Solar Project,” Murphy said. “We realized about a 50-percent reduction in the property tax rate for the solar property. For Sierra, which leases the property, that’s a big chunk of money—about $100,000 for the year.”

Every December, external auditors make a one-week, on-campus visit, followed by another two-week visit in February. During this time, auditors examine AzGT’s accounting methods, ask for hundreds of documents and question many employees.

Pete Scott, chief financial officer for AzGT, thanked Murphy’s team and the many others who provided data and information for the audit. “Kudos to you, Arnold, and to your team for another successful, clean audit,” he said. “The huge amount of work that goes on each year in support of the audit is unseen by many but is greatly appreciated.”
