Portfolio monitoring

Revalue a book on a schedule and track movement over the life of a loan or policy — with confidence reported alongside every value.

A reference that has no position in the price.

Blue Water Index does not list boats, broker transactions, lend or underwrite. For a credit or underwriting file, that separation is the point.

Origination

Value and range

Evidence attached to the credit file.

Renewal

Re-valued on schedule

Agreed-value reviews at each renewal.

Total loss

Traceable evidence

Dated market evidence as it stood.

Portfolio

Monitored over time

Movement tracked across the book.
