Brown is the second highest elected official in Houston City Government (the “City”) and its Chief Financial Officer. The Office of the Houston City Controller superintends the fiscal affairs of the City. This includes conducting audits, managing investments and debt, preparing financial statements and providing leadership on policy issues pertaining to the City’s financial health. Controller Brown thus serves as an independently elected “financial watchdog” over City government’s fiscal affairs. The Treasury Division is responsible for managing the City’s $3.5 billion investment portfolio in accordance with state law and the City’s investment policy. Fitch has awarded the City’s general investment its highest portfolio rating, AAA. The Treasury Division is also responsible for overseeing a debt program of approximately $10.2 billion. The City has multiple general obligation commercial paper programs with total authorization of $725 million. The current issuance capacity of the commercial paper programs is $725 million which is supported by credit facilities or lines of credit. Additionally, the City has an appropriation facility supported by a forward bond purchase agreement in the amount of $200 million. The City has seven auction-rate security issues, six series of variable rate demand obligation bonds, two SIFMA indexed notes, and three interest rate swaps with a total notional amount of $902 million and credit agreements totaling $ 2.1 billion. The City’s general obligation debt is rated Aa3 by Moody’s; AA- by Standard and Poor’s; and AA by Fitch Ratings. The Audit Division adheres to recognized professional auditing standards (Government Auditing Standards and International Standards as issued by the Institute of Internal Auditors). During Fiscal Year 2017, the Audit Division engaged in 23 Audits and Special Projects that produced 11 Audit Reports as posted on the Controller’s website. The audits and projects performed focused on risk assessment, contract compliance, performance and efficiency, process reviews, ongoing monitoring, consideration of fraud, waste or abuse, and quality assurance.
