How are ASX 300 companies selected?

Constituents are selected by a committee from Standard & Poor’s (S&P) and the Australian Securities Exchange (ASX).
All companies listed on the Australian Securities Exchange (ASX) are ranked by market capitalisation. Exchange traded fund (ETFs) and Listed Investment Companies (LICs) are ignored. The top 300 ASX stocks that meet minimum volume and investment benchmarks then become eligible for inclusion in the index.
Rebalances are conducted biannually in March and September. If a significant event occurs (e.g. delisting, merger, etc.) an intra-quarter removal may be conducted. Unlike other indices, a replacement is not added to the index until the next rebalance date.
