Being too eager to post the results for the year, some readers were right to point out that the MA cap up to 31 Dec 2019 was $57,200. Revision for MA cap to $60,000 begins on 01 Jan 2020. Therefore, the interests earned for MA account for 2019 would overflow to SA.
I checked back today on the 04 Jan 2020 and yes, the overflow has been rightfully corrected. Thanks for pointing this out!
MA has $2,264.11 more to go towards BHS.
