Khud Kisi ko Khabar Nahin: Section 43A aur Share Capital

Main to khud hi confused hoon. Section 43A mein lagta hai ki company ke share capital ke badle mein jo debentures issue kiye jate hain unhone company ko liability ke baare mein bina sharte aur condition ke kisi debt ko pay karne ka vada diya hai, par Section 46 mein vahi sharte aur conditions mention hain jo koi debenture holder apne debentures ke badle mein kisi debt ke liye company se unka vada lene ke liye karega. Ya phir kya hai, main jaanta hi nahi. Koi share capital ke badle diya gaya debt kisi bhi condition ke baare mein nahi hai par kya Section 43A ke maan me woh debt aur kuch aur hai?
