某公司属于国有控股企业,最高权力机构是股东大会,执行机构是董事会,另外,还设有职工代表大会以及各职能部门、分公司等。其内部控制制度及业务活动情况如下:
(1)会计出纳分设。财务部经理的妻子担任出纳,并兼任满足行政部门需要的日常业务,亲自办理取款、购买、报销等手续。支票等票据由会计保管,支取款项的印章都由总经理亲自保管。
(2)材料采购等由供应部经理审批、专门采购员实施。根据规定,各项费用由总经理签字都可报销,某日出纳在采购时发现当地主要媒体宣传另一公司A产品正在开展促销活动,称其为高科技产品,可以替代本企业主要原料并能够节约成本30%,促销时间仅仅两天。采购员认为时间过于紧张,来不及请示供应部经理,因此直接电告企业总经理,总经理决定采购10吨,价税合计100万元。出纳当即采购并由仓库验收入库,经总经理签字,办理了货款支付手续。后来生产车间反映,该批材料不适应生产要求,只能折价处理,造成损失 30万元。总经理指示调整成本预算,将30万元损失记入正常材料耗费。
(3)办理销售、发货、收款三项业务的部门分别设立,同时,为考虑到销售部门比较熟悉客户情况,也便于销售部进行业务谈判,确定授权销售部兼任信用管理机构。对大额销售业务,销售部可自主定价、签署销售合同。为逃避银行对公司资金流动的监控,企业在销售业务中尽可能利用各种机会由业务员向客户收取现金,然后交财务部存放在专门的账户上。某月销售业务员甲联系到一个大客户,办理300万元的销售任务,并将款项交财务部入账。次月,该业务员谎称对方要求退货,并自行从其他企业低价购入同类商品要求仓储部门验收入库,仓储部门发现商品商标都丢失,但未进行进一步查验,直接办理了各项手续(但没有出具质检报告)。财务部将退货款项转入业务员提供的银行账号。
要求:分析企业内部会计控制方面存在什么问题,并说明应该如何修正。
