AR Securitization

I’m getting confused on the effect of AR securitizations on the balance sheet. According to the example on page 60 of CFAI v. 2, securitizations increase assets and liabilities. According to the solutions to problems 16 and 17 on page 363 of CFAI v. 2, securitization decreases the assets and liabilities. Can someone please clarify this? Thanks.

It really depends on whether you are required to consolidate the SPV that acquires the AR.
