<p><b>New page</b></p><div>📈 '''Equity security''' is an ownership instrument — most commonly a share of stock — that represents a proportional claim on a company's assets and earnings. Within the insurance industry, equity securities appear on both sides of the balance sheet: insurers hold them as part of their [[Definition:Investment portfolio | investment portfolios]], and insurance-focused holding companies issue them to raise [[Definition:Equity capital | equity capital]]. The treatment of equity securities on an insurer's books is governed by [[Definition:Statutory accounting principles (SAP) | statutory accounting principles]], which impose distinct valuation and [[Definition:Admitted asset | admissibility]] rules compared to generally accepted accounting principles.<br />
<br />
🔍 Carriers invest [[Definition:Premium | premium]] float and [[Definition:Surplus | surplus]] in equity securities to generate [[Definition:Investment income | investment income]] and capital appreciation, though regulators limit the proportion of an insurer's portfolio that can be allocated to equities because of their inherent price volatility. Under the [[Definition:National Association of Insurance Commissioners (NAIC) | NAIC]] framework, common stocks held by insurers are typically reported at fair value with unrealized gains and losses flowing through surplus rather than the income statement. [[Definition:Life insurance | Life insurers]] with long-duration liabilities may hold larger equity allocations to match growth expectations, while [[Definition:Property and casualty insurance | property and casualty]] writers often maintain more conservative positions to ensure liquidity for [[Definition:Claims | claims]] payouts.<br />
<br />
🛡️ Proper management of equity security exposure is essential to an insurer's overall [[Definition:Risk management | risk management]] discipline. A sharp market downturn can erode surplus, trigger [[Definition:Rating agency | rating agency]] downgrades, and even threaten compliance with [[Definition:Risk-based capital (RBC) | risk-based capital]] thresholds. For this reason, [[Definition:Chief investment officer | investment teams]] employ diversification limits, hedging strategies, and stress-testing scenarios calibrated to insurance-specific liability profiles. On the other side of the table, when an insurer or [[Definition:Insurtech | insurtech]] issues equity securities to the public or private investors, the terms and governance rights attached to those securities influence everything from strategic direction to [[Definition:Mergers and acquisitions (M&A) | M&A]] activity across the sector.<br />
