Mess Effect 2 - Upgrades

Due to several gameplay changes, your character's level and abilities will not transfer over to Mass Effect 2. However, the game will acknowledge your character's level and morality and adapt it in ways that map across to the new system as well. The higher the level of the imported character, the greater the bonuses granted upon importing.

A portion of the character's Paragon/Renegade points (up to 190 each, which requires the bar(s) to be 50% full[1]) are transferred over.
Importing a level 1 through level 49 character will grant 1,000 XP (the player starts at level 2), 20,000 credits, and 2,500 of each resource.
Importing a level 50 through level 59 character will grant 2,000 XP (the player starts at level 3), 30,000 credits, and 5,000 of each resource.
Importing a level 60 character will grant 4,000 XP (the player starts at level 5), 50,000 credits, and 10,000 of each resource.
Having the "Rich" achievement from Mass Effect will grant an additional 100,000 credits.
The import bonuses will stack with the Mass Effect 2 completion starting bonuses (200,000 credits and 50,000 of each resource).

Note: In Legendary Edition the player starts Mass Effect 2 with 10% of their credits carried over from Mass Effect in addition to the above level bonuses. This seems to be a replacement for the "Rich" achievement.
