For safety and soundness purposes, no later than 90 days after its fiscal year end, each savings bank is required to submit to the Department the results and findings of an independent audit of its financial statements and all correspondence reasonably related to the audit. The audit is to be performed in accordance with generally accepted auditing standards and the provisions of the FDIC set forth in 12 C.F.R. §363.2 and §363.3, with the exception of any matters specifically addressed by this section, the Texas Savings Bank Act, or the rules (regulations) adopted thereunder.
