Transition from the IEX ATS to Investors Exchange

The ATS will transition to the Exchange using a security-by-security phase-in approach similar to that used by Electronic Communication Networks (“ECNs”) who transitioned to national securities exchanges in the past.

Pre-launch Period: There will be a three-week pre-launch period during which participants will be able to enter test orders on the Exchange using test symbols.

Phase-in Period: Following the launch date, there will be a two-week phase-in period during which securities currently trading on the ATS will be migrated from the ATS to the Exchange. Once a security is migrated from the ATS to the Exchange, it will no longer be available for trading on the ATS and will only be available for trading on the Exchange. Once the Exchange begins trading its first non-test security, it will operate in conjunction with the ATS until all securities are fully transitioned.

The schedule is as follows:

• August 1 – 18 (M – Th): Test symbols transition (CBO, CBX, ZBZX, ZJZZT, ZTEST, ZVV, ZVZZT, ZWZZT, ZXZZT) (Pre-launch Period)
• August 19 – 23 (F – Tu): Two non-test securities (VG, WIN) (“Launch Date”, Phase-in Period begins)
• August 24 – 26 (W – F): Ten non-test securities (VALE.P, VG, VHC, VIAV, VIP, VLY, WIN, XOMA, YINN, ZIOP)
• August 29 – 30 (M – Tu): All symbols starting with ‘Y’ – ‘Z’, VALE.P, VG, VHC, VIAV, VIP, VLY, WIN, XOMA
• August 31 – September 1 (W – Th): All symbols starting with ‘V’ – ‘Z’
• September 2 (F): All symbols (‘A’ – ‘Z’) (Phase-in Period ends, ATS ceases operation)
