iShares LifePath Retirement ETF (IRTR US) – Portfolio Construction Methodology

The investment strategy driving the actively managed iShares LifePath Retirement ETF allocates across a conservative, globally diversified mix of iShares ETFs spanning U.S. and non-U.S. equities, investment-grade bonds, Treasuries, TIPS, securitized credit and cash equivalents to support retirement-stage outcomes. BlackRock’s multi-asset team sets strategic weights using long-horizon capital-market assumptions and a LifePath glidepath calibrated for investors at or in retirement; eligibility centers on liquid, transparent underlying ETFs with robust tracking and market depth. Portfolio construction targets broad factor and term diversification with volatility and drawdown awareness, using allocation bands and optimizer-aided risk budgeting; derivatives may be used for efficient exposure and liquidity management where permitted. The fund rebalances periodically and in response to market moves to remain within bands and preserve inflation-hedging and equity-risk budgets; trims and reallocations occur when relative expected returns, risk estimates or liquidity conditions shift.
