10. Summary Various activities to make a concrete business plan including the telescope optics (M1/M2/M3), instruments, etc. Four 2 nd generation instruments have been proposed. We would like to submit the Construction Budget plan from FY2012 to 2020 (TBD: ~$350M) on June 2011 → Need agreements and negotiation with TMT & partners Activate TMT science symposium and science cases → Invitation of TMT SAC & partner members for such meetings in Japan 10
