Explain investment of bank for illiquidity premium

Question

When my company is not listed, therefore the investment banks apply an illiquidity premium. In fact, they say this is an illiquidity premium but then they call this a small cap premium. Only one of the banks, apparently based upon Titman y Martin (2007), that added the given small cap premiums as: “0.91 percent if the capitalization is situated among $1,167 and $4,794 million; 1.70 percent if the capitalization is among $331 and $1,167 million; 4.01% if this is lower than $331 million”. The other bank adds 2% since historically the return of small companies was smaller than those big companies. Which one is more suitable?
