The Swiss insurance company said the deal would increase its presence across the United States.
The deal would make it the third-largest vision insurer in the country.
The insurer's profit drop reflected a 13% decline in net investment income and $710 million in net derivative losses.
The SEC says the insurer failed to maintain a sufficient system of internal controls, resulting in an improper release of annuity reserves.
The company agreed to pay $1 million to resolve accusations related to its pension risk transfer business.

The $6 billion deal could be a harbinger of more such asset de-risking moves by other defined-benefit plan sponsors.

The insurer says it underestimated its group annuity reserves because of "a material weakness in internal control over financial reporting.”
The deal comes as insurers are buying pension plans at a record rate.
The sector's increased contribution to systemic risk necessitates a "more macroprudential approach" to regulating it, the IMF says.
MetLife's victory in a legal battle with regulators could encourage other institutions to challenge the "systemically important" designation.
