DOE regulations for unearned Title IV funds	These funds must be returned in a timely manner, generally within 45 days of the date the school determines that the student has withdrawn. Under DOE regulations, failure to make timely returns of Title IV program funds for 5% or more of students sampled in a school’s annual compliance audit in either of its two most recently completed fiscal years could result in a requirement that the school post a letter of credit in an amount equal to 25% of its prior-year returns of Title IV program funds.
