Book Description
This paper investigates how accounting rule reform affects the usage of conditional conservatism in the property-liability (P&L) insurance industry. More specifically, whether the accounting rule changes that strengthen the internal control over financial reporting and improve the financial reporting transparency reduce insurers' incentives for conservatively reserving. The P&L insurance industry is a perfect setting for studying accruals and accounting conservatism because it has specific and detailed firm-year level data about loss accrual development. We develop a new method of assessing conditional conservatism, measuring it as the concavity of an insurer's loss development curve. We study the U.S. domiciled P&L insurance companies from 1995 to 2015. Using a diff-in-diff identification strategy, we find that the level of conditional conservatism is significantly reduced after the enactment of the Sarbanes-Oxley Act (SOX) Section 404 and the Model Audit Rule (MAR), both of which increased board oversight of internal risk management. Our result indicates that complying with additional disclosure requirements reduces P&L insurers' incentives to use conditional conservatism to mitigate regulatory monitoring costs. With fewer reserves, insurers may become less resistant to unexpected or catastrophic losses and face greater insolvency risk. The paper's results also shed light on the question of which should be an appropriate measure of financial reporting quality given a goal of reducing bankruptcy risk: transparency and accuracy or conservatism.
