Visa Inc shares were down about 0.3% in after-hours trading on Tuesday after the payments processor disclosed in a Form 8-K — a filing used to report major events to investors — that it updated the conversion rates on its class B-1 and B-2 common stock following a $500 million deposit into its U.S. litigation escrow account. Visa said the B-1 conversion rate fell to 1.5491 from 1.5549 and the B-2 rate fell to 1.5108 from 1.5223, cutting the “as-converted” class B-2 share count by about 1.38 million and the class B-1 count by about 27,782; the filing, signed by Chief Financial Officer Chris Suh, said the adjustment has “the same effect on earnings per share as repurchasing” class A shares.
