Mergers are great when you\u2019re talking about chocolate and peanut butter. But when you\u2019re talking about merging 401(k) plan assets, it\u2019s not always a smooth combination. Plan mergers, whether due to acquisitions, company restructuring, or TPA transitions, can create an administrative nightmare if the details aren\u2019t handled with surgical precision. As a plan provider, you\u2019ll quickly learn that merged assets and sloppy reconciliation are the kind of problems that turn your clean 5500 into a red flag for auditors and regulators.<\/p>\n
The Merged Assets Time Bomb<\/strong><\/p>\n When two or more plans merge, the assumption is simple: assets from Plan A roll into Plan B, participants and balances are consolidated, and life goes on. But ERISA doesn\u2019t reward assumptions\u2014it punishes sloppiness. If the assets don\u2019t reconcile perfectly, if forfeiture accounts or outstanding loans don\u2019t match, or if there are lingering \u201cghost\u201d accounts that never transferred, the result is a mess that compounds every year until someone has to unwind it under pressure.<\/p>\n The problem often begins during the transfer process. Custodians send over assets that don\u2019t line up with participant records. Old plan numbers get confused with new ones. Sometimes, participant-level data arrives incomplete or mislabeled, and no one realizes it until the next plan year\u2019s audit. The financial data might look \u201cclose enough,\u201d but close enough doesn\u2019t satisfy auditors or the Department of Labor.<\/p>\n Reconciliation\u2014The Lost Art<\/strong><\/p>\n Reconciliation isn\u2019t glamorous work, but it\u2019s the backbone of clean plan accounting. Every dollar in the trust should have a name, and every transaction should make sense. After a merger, that means going line by line, making sure every asset transferred matches the participant balances and historical data from the predecessor plan.<\/p>\n Too often, reconciliation is left to chance or rushed because \u201cwe just need to get the plan live.\u201d But the moment you cut corners, you inherit someone else\u2019s problem\u2014and that problem becomes yours once the audit comes around. When the auditor asks why the trust doesn\u2019t reconcile to the participant ledger, or why the forfeiture balance ballooned from $12,000 to $48,000 with no explanation, \u201cit came from the merger\u201d isn\u2019t an answer\u2014it\u2019s an indictment.<\/p>\n Form 5500\u2014Garbage In, Garbage Out<\/strong><\/p>\n If you\u2019ve ever heard the phrase \u201cgarbage in, garbage out,\u201d it applies perfectly to the 5500. When plan data isn\u2019t reconciled before filing, you\u2019re certifying inaccurate information under penalty of perjury. Think of it this way: the 5500 is the plan\u2019s public face, and if it shows inconsistent participant counts, mismatched assets, or unexplained adjustments, it\u2019s like showing up to court in a stained suit and flip-flops. The DOL notices, the IRS notices, and eventually, participants notice.<\/p>\n Merged plans with unclean data often lead to 5500s that don\u2019t tell the full story. One plan might report prior-year assets that don\u2019t match the carryforward from the predecessor plan. Or worse, the audit notes a \u201cqualified opinion\u201d because the records are incomplete. Once that happens, you\u2019re on the DOL\u2019s radar\u2014and that\u2019s a place no one wants to be.<\/p>\n Best Practices\u2014Avoiding the Merged Asset Mayhem<\/strong><\/p>\n 1. Audit Before You Merge: Don\u2019t just merge assets, review them. Reconcile old plan balances before a single dollar moves. Identify missing data, stale loans, or unallocated forfeitures.<\/p>\n 2. Map Provisions Carefully: Make sure every plan feature (eligibility, match, vesting, loans) aligns correctly. A misalignment can lead to operational errors that spiral into disqualification issues.<\/p>\n 3. Communicate Between Teams: HR, payroll, the recordkeeper, and the TPA all need to be on the same page. Merged plans fail when each group assumes someone else has \u201cchecked the math.\u201d<\/p>\n 4. Document the Process: Keep a written record of how the merger was handled\u2014asset transfer confirmations, reconciliation notes, and communication logs. When the auditor asks, \u201cHow do you know these assets were correct?\u201d, documentation saves the day.<\/p>\n 5. Clean Up Before Filing: Never rush a 5500 just to meet the deadline. Extensions exist for a reason. A clean, accurate 5500 a few weeks late is better than a fast one that triggers a DOL letter.<\/p>\n The Takeaway<\/strong><\/p>\n As an ERISA attorney, I\u2019ve seen too many \u201cmerger disasters\u201d where plan sponsors trusted that everything would just work out. Spoiler alert: it rarely does. Merged assets without proper reconciliation are like uncashed checks and forgotten passwords, they create confusion, liability, and unnecessary exposure.<\/p>\n The lesson? Don\u2019t let the merged plan be your problem child. Get reconciliation right, make the 5500 reflect reality, and don\u2019t rely on hope as a compliance strategy. Because in the ERISA world, merged assets that don\u2019t add up eventually make everyone\u2019s numbers look bad.<\/p>\n <\/span><\/p>","protected":false},"excerpt":{"rendered":" Mergers are great when you\u2019re talking about chocolate and peanut butter.
