Thank you, Mr. Chair. I guess what I'm trying to get at here is if we set out ahead of time that certain equipment or infrastructure needs upgrading or replacing or maintenance or repair at certain times, it's generally based on our expected costs of what would happen if we didn't do those upgrades or maintenance or repairs, you know, things might start to break down or they don't work efficiently, or. Do we expect any increase costs in repair, maintenance, O and M, from delaying upgrades that NTPC has previously identified that it requires? Thank you, Mr. Chair.
