Japanese Posting Fee To Be Split Over Two Years

The posting fee of $20 million for Japanese players will be paid in two installments, $13 million the first year and $7 million the second year. Why? You got me, but that's the way it is apparently according to MLB Trade Rumors. The idea was to give teams a more realistic shot at going after the talent but is $7 million really that big of an amount for a team, especially when it doesn't count against the luxury tax or overall payroll? Probably not, something is fishy here.
