Loans Subject to Repurchase Right from Ginnie Mae

Forward loans are sold to Ginnie Mae in conjunction with the issuance of mortgage backed securities. The Company, as the issuer of the mortgage backed securities, has the unilateral right to repurchase any individual loan in a Ginnie Mae securitization pool if that loan meets certain criteria, including being delinquent greater than 90 days. Once the Company has the unilateral right to repurchase a delinquent loan, it has effectively regained control over the loan and recognizes these rights to the loan on its consolidated balance sheets and establishes a corresponding repurchase liability regardless of the Company’s intention to repurchase the loan. The amount as of December 31, 2019 includes $336 attributable to Pacific Union.
