The NFF Corporation has announced plans to acquire LE Corporation. NFF is trading for $$$$10\mathrm{.}00$ per$$share$,$ and LE is trading for $$$$38\mathrm{.}00$ per$$share$,$ implying a premerger value of LE of approximately $$$$9\mathrm{.}28$ billion. If the projected synergies are $$0\mathrm{.}98$billion$,$ what is the maximum exchange ratio NFF could offer in a stock swap and still generate a positive$$NPV$?$
