MISSING, LOST, STOLEN, OR RECOVERED GOVERNMENT PROPERTY The Navy has long recognized the importance of maintaining statistics to determine where, when, and how Navy property was missing, lost, or stolen. Based on this premise, missing, lost, stolen, or recovered (MLSR)  government  property  reports  must  be submitted to proper authorities within the Department of the Navy (DON). DON’s ultimate goal is to improve the Navy’s physical security program. To ensure the MLSR program’s success, commands must report all MLSR  incidents  and  accurately  describe  the circumstances. The major benefit will be significant improvements in ship and shore physical security programs. The reporting of these incidents by an MLSR report is independent of the Naval Investigative Service’s request for investigative assistance. Details of the MLSR program are given in SECNAVINST 5500.4D. All master and senior chiefs should be familiar with this instruction. It specifically covers the following categories of materials; MLSR reports must be made when items in these categories are missing, lost, stolen, or recovered: All serialized property having a value of 0 or more that is owned, leased, rented, or borrowed by the Navy. All unserialized property having a value of 0 or  more  that  is  owned,  leased,  rented,  or borrowed by the Navy. All unserialized property that is owned, leased, rented, or borrowed by the Navy considered to be sensitive items regardless of the actual or estimated value. Sensitive items for this purpose are considered to be precious metals, highly technical devices, and classified material. All serialized or unserialized property items exceeding 0 (even though a single item does not exceed the 0 minimum) involved in a cumulative loss through the same incident. In addition to MLSR reports, surveys are also required. Specific procedures for conducting surveys are given in supply publications. The basic procedures are described in the following paragraphs. SURVEYS A survey is the procedure required when Navy property (except incoming shipments) is lost, damaged, or destroyed. The purpose of a survey is to determine the responsibility for the lost, damaged, or destroyed property and to determine the actual loss to the government. A true determination can be made only through a thorough research of the facts surrounding the loss or damage. This research should not be limited to simply verifying statements of interested parties. It must be broad enough to ensure the full protection of the interests of the government, as well as the rights of the individual(s) or Navy activities concerned. A review is required to prove or refute statements of interested persons and to place responsibility where it belongs. Preliminary Research Immediately  upon  the  discovery  of  the  loss, damage, or destruction of government property, the 6-18
