RSO
The call RSO price is given by
C(S,t,r,σ,δ;α,λ,β,K) = βe⁻ᵟᵗSN(d₁) - λe⁻ᵅᵟᵗYN(d₂)
The put RSO price is given by

where
S is the initial underlying price
t is the time to option expiry in annual units
r is the effective flat continuously compounded interest rate.
σ is the flat lognormal volatility of the price of the option's underlying.
δ is the flat continuously compounded dividend yield of the option's underlying.
d₁ = [(1-α)ln(S/K) - lnλ + lnβ + (1-α)(r-δ+σ²/2)t] / [(1-α)σt¹ᐟ²]
