I know that there are sometimes booklets or fliers that describe a company's benefits, but what you are describing is not something I am familiar with.
The amount of money you can receive when you retire is called a pension. I think the procedures for administrating pension plans are different from country to country. In the U.S. there is no book or notebook associated with pensions as far as I know. The "statement of benefits" is the only thing I can think of that comes close to what you are describing. Sorry!
